    Identification of familial, more homogenous characteristics of obsessive-compulsive disorder (OCD) may help to define relevant subtypes and increase the power of genetic and neurobiological studies of OCD. While factor-analytic studies have found consistent, clinically meaningful OCD symptom dimensions, there have been only limited attempts to evaluate the familiality and potential genetic basis of such dimensions. Four hundred eighteen sibling pairs with OCD were evaluated using the Structured Clinical Interview for DSM-IV and the Yale-Brown Obsessive Compulsive Scale (YBOCS) Symptom Checklist and Severity scales. After controlling for sex, age, and age of onset, robust sib-sib intraclass correlations were found for two of the four YBOCS factors: Factor IV (hoarding obsessions and compulsions (p = .001) and Factor I (aggressive, sexual, and religious obsessions, and checking compulsions; p = .002). Smaller, but still significant, familiality was found for Factor III (contamination/cleaning; p = .02) and Factor II (symmetry/ordering/arranging; p = .04). Limiting the sample to female subjects more than doubled the familiality estimates for Factor II (p = .003). Among potentially relevant comorbid conditions for genetic studies, bipolar I/II and major depressive disorder were strongly associated with Factor I (p sibling pairs with OCD are familial with some gender-dependence, exhibit relatively specific relationships to comorbid psychiatric disorders and thus may be useful as refined phenotypes for molecular genetic studies of OCD.

    Previous studies have explored differences in psychosocial and familial factors between women who develop anorexia nervosa and those who do not. However, these studies have generally used between-group comparisons. This study looks at the environmental factors which may be antecedents of anorexia nervosa looking at sister pairs where one had anorexia nervosa and the other did not. A paired design was used to compare anorexic women with an unaffected sister on a number of background variables, including sibling interaction, parental care, peer group characteristics and other events unique to the individual. The Sibling Inventory of Differential Experience (SIDE) was used to determine non-shared environment. Out of an initial sample of 148 women with past or current anorexia nervosa, 28 were identified who had sisters with no reported history of eating disorders and who also consented to complete the questionnaire. Anorexic sisters perceived more maternal control and reported more antagonism towards and jealousy of their sisters than did unaffected sisters. In addition, anorexic women reported having had fewer friends and boyfriends than their sisters. These results confirm the perceived differences in background environment between women with and women without anorexia nervosa. These issues are discussed in relation to behavioural genetics, family dynamics and psychosexual development.

  4. Bullying in the family: sibling bullying.

    Sibling relationships have a substantial and lasting effect on children's development. Many siblings experience some occasional conflict, however, up to 40% are exposed to sibling bullying every week, a repeated and harmful form of intrafamilial aggression. We review evidence on the precursors, factors relating to peer bullying, and mental health consequences of sibling bullying. Parenting quality and behaviour are the intrafamilial factors most strongly associated with bullying between siblings. Sibling bullying increases the risk of being involved in peer bullying, and is independently associated with concurrent and early adult emotional problems, including distress, depression, and self-harm. The effects appear to be cumulative, with those children bullied by both siblings and peers having highly increased emotional problems compared with those bullied by siblings or peers only, probably because they have no safe place to escape from bullying. The link between sibling and peer bullying suggests interventions need to start at home. Health professionals should ask about sibling bullying and interventions are needed for families to prevent and reduce the health burden associated with sibling bullying.

    Prospective associations among parent-adolescent acceptance and familism values in early and middle adolescence and sibling intimacy in late adolescence and young adulthood were assessed in 246 Mexican-origin families. Older sibling gender and sibling gender constellation were investigated as moderators of these associations. Sibling intimacy was stable over time and younger siblings with older sisters reported higher levels of sibling intimacy than those with older brothers. As predicted, stronger familism values were associated with greater sibling intimacy, but this link was evident only for older sisters and for girl-girl dyads. The links from mother- and father-acceptance to sibling intimacy also depended on the gender constellation of the sibling dyad: Higher levels of maternal warmth were associated with greater sibling intimacy for older sisters and girl-girl sibling pairs but higher levels of paternal warmth were linked to greater sibling intimacy only for older siblings in mixed-gender sibling dyads. Findings are consistent with prior research on the role of gender in family relationships but extend this work to encompass the effects of both parents' and siblings' gender, as well as the role of sociocultural values in parents' socialization influences. © 2015 Family Process Institute.

    The clinical spectrum of cystic fibrosis (CF) is influenced by the cystic fibrosis transmembrane conductance regulator (CFTR) genotype. However, variable courses of the disease were demonstrated among patients with identical genotypes. Since siblings share identical CFTR mutations and environmental factors, they can serve as a model to assess the effect of modifier genes on disease expression, and also to evaluate cross-infection. The aim of this study was to compare disease expression among siblings with CF. All sibling pairs treated at 7 CF centers in Israel were included in the study. Data were collected from patients' medical charts. Fifty families with at least 2 siblings were identified. As expected, the second-born sibling was diagnosed at an earlier age compared to the first-born. The mode of CF presentation at diagnosis showed significant familial concordance. In the families where the first sibling presented with gastrointestinal manifestations, 79% of the second siblings also presented with gastrointestinal manifestations. When gastrointestinal manifestations were absent in the first sibling, only 12% of the second siblings presented with gastrointestinal manifestations (P sibling presented with respiratory symptoms, 60% of the second siblings presented with the similar symptoms. However, when the first sibling presented without respiratory symptoms, only 12% of the second siblings presented with respiratory symptoms (P sibling had MI, 8 (80%) of the subsequent siblings had MI. On the other hand, in the 39 families where the first-born sibling did not have MI, only 2 (5%) subsequent siblings had MI (P siblings. P. aeruginosa grew from sputum in 89% of our study patients. When P. aeruginosa was isolated from the first-born patient, 91% of the second siblings were also positive for P. aeruginosa, whereas when the initial sibling was not a carrier of P. aeruginosa, only 50% of subsequent siblings were positive (P sibling than in the first for the two

    This study examined communication interaction patterns when one sibling had a developmental disability as well as the role of communication skills in sibling relationship quality. Thirty sibling dyads were categorized into one of three communication status groups: emerging, context-dependent, and independent communicators. Independent communicators and their siblings did not differ in terms of syntactic complexity but typically developing siblings dominated the interaction and exhibited greater lexical diversity regardless of communication status. Communication status did not impact the warmth/closeness, rivalry, or conflict in the sibling relationship, but siblings of independent communicators engaged in the greatest amount of helping and managing behaviors. These results represent a first step in understanding the role of communication skills in the sibling relationship for families of children with disabilities.

The paper by Nowak et al. has the evolution of eusociality as its title, but it is mostly about something else. It argues against inclusive fitness theory and offers an alternative modelling approach...... that is claimed to be more fundamental and general, but which, we believe, has no practical biological meaning for the evolution of eusociality. Nowak et al. overlook the robust empirical observation that eusociality has only arisen in clades where mothers are associated with their full-sibling offspring; that is......, in families where the average relatedness of offspring to siblings is as high as to their own offspring, independent of population structure or ploidy. We believe that this omission makes the paper largely irrelevant for understanding the evolution of eusociality....

  14. Saviour siblings and collective family interests.

    Taylor-Sands, Michelle

    2010-09-01

    In this article, I will explore the ethical concerns arising out of the use of preimplantation tissue typing (PTT) to create saviour siblings. There are two main ethical concerns about the welfare of the child to be born as a result of PTT. The first is whether the child to be born is treated as a commodity, as simply a means to save the life of his or her sibling. The second is whether the child to be born will be harmed as a result of PTT, either physically, psychologically or socially. These two ethical concerns reflect an individualistic approach to the welfare of the child, whose interests are treated as largely separate to the interests of other family members. I will argue that the welfare of the child born as a result of PTT should be conceived more broadly to include not only the child's individual interests, but also the collective interests the child shares with his or her family. I base this broader conception of welfare on the notion of human flourishing, which recognises that the welfare of a child is inextricably connected to the welfare of the intimate collective that is his or her family. The collective interests of intimate family members are particularly relevant in the context of PTT, as the members are engaged in a shared journey to save the life of an ill child.

    2017-09-01

    The current study explored whether older sibling mentalization moderated the relationship between familial risk for internalizing symptoms and the development of future internalizing problems in the younger siblings, referred to as target children. Data were collected on 397 older siblings at Time 1 (T1) when target children were newborn and their older siblings were on average 2.61 years old (SD = .75). Target children were on average 1.60 years old at Time 2 (T2). Internalizing problems were assessed via mother and partner reports. Familial risk was operationalized as the average of all older siblings' level of internalizing problems. Older sibling mentalization, indexed by internal state talk and reasoning, was observed and coded during a sibling pretend-play interaction at T2. Results revealed a significant interaction between familial risk of internalizing problems and older siblings' mentalizing abilities, showing that familial risk was related to target children's internalizing problems in the absence of sibling mentalization. Familial risk was not associated with target children's internalizing problems when siblings demonstrated mentalizing abilities. Findings support the need to consider sibling mentalization as a protective factor for children's internalizing problems. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    2017-01-01

    Abstract Introduction: Maternal smoking during pregnancy has been associated with an increased risk for psychiatric morbidity. We further studied this with Finnish siblings to control for genetic/familial factors. Methods: From the Finnish Medical Birth Register, sibling pairs were selected as the first two children born 1987–1995 to the same mother (n = 150 168 pairs), along with information on maternal smoking (no smoking/smoking). Information on the children’s psychiatric diagnoses related to outpatient care visits (1998–2013) and inpatient care (1987–2013), and the mothers’ psychiatric morbidity (1969–2013) was derived from the Finnish Hospital Discharge Register. The first pair analysis compared siblings of mothers who only smoked in the first pregnancy (Quitters, 4.7%) and mothers who smoked in both pregnancies (Smokers, 9.6%); the second analysis included mothers who smoked only in the second pregnancy (Starters, 3.3%) and mothers who did not smoke in either pregnancy (Nonsmokers, 77.5%). Smoking information was missing for 5.0% of pairs. Psychiatric morbidity of the siblings and mother was included in the statistical analyses. Results: The risk of psychiatric diagnoses was significantly lower for the second child of quitters (adjusted OR 0.77, 95% CI 0.72–0.83) compared to the risk among smokers. A higher risk for psychiatric diagnoses was found for the second child of starters (1.39, 1.30–1.49) compared to the risk among nonsmokers. The effect of smoking was more robust for externalizing diagnoses. Conclusions: Maternal smoking was independently associated with a higher risk for psychiatric morbidity in children, even when controlling thoroughly for genetic and familial factors. Implications: Maternal smoking during pregnancy has an independent effect on the risk of psychiatric morbidity in children, even after controlling for non-measurable genetic/familial factors by using a sibling pair design. The effect of maternal smoking was robust

    This paper reviews the evidence on the significance of sibling inclusion in family interventions and support during early psychosis. This narrative review presents the current research related to the importance of family work during early psychosis, the needs and developmental significance of siblings during adolescence and early adulthood, the protective effects of sibling relationships, and the characteristics of early psychosis relevant to the sibling experience. It will also review the evidence of the sibling experience in chronic physical illness and disability, as well as long-term psychotic illness. Despite the evidence that working with families is important during early psychosis, siblings have been largely ignored. Siblings are an important reciprocal relationship of long duration. They play an important role in development during adolescence and early adulthood. These relationships may be an underutilized protective factor due to their inherent benefits and social support. Developmental theories imply that early psychosis could negatively impact the sibling relationship and their quality of life, effecting personality development and health outcomes. The evidence shows that adolescent physical illness or disability has a significantly negative impact on the sibling's quality of life and increases the risk for the onset of mental health issues. Long-term psychotic illness also results in negative experiences for siblings. Current evidence shows that siblings in early psychosis experience psychological distress and changes in functional performance. Further research using standard measures is required to understand the impact early psychosis has on the sibling relationship and their quality of life. © 2013 Wiley Publishing Asia Pty Ltd.

    To examine the association between intrauterine growth and intelligence. Population based birth cohort study of sibling pairs born within a maximum of three years of each other. Mater-University women and children's hospital, Brisbane, Australia. 235 (470 children) sibling pairs. Among one randomly selected sibling from each pair verbal comprehension at age 5, general intelligence at age 14, and reading ability at age 14 increased linearly with increasing gestational age and sex standardised birth weight z scores. With adjustment for maternal age, race, and smoking during pregnancy, birth order, family income, and parental education the associations with verbal comprehension at age 5 and general intelligence at age 14 remained, whereas the association with reading ability at age 14 was attenuated to the null. Within sibling pairs, differences in intrauterine growth were positively associated with differences in verbal comprehension at age 5 (test score difference per one unit difference in birth weight z score = 1.52 (0.11 to 3.26)) and general intelligence at age 14 (1.09 (0.01 to 2.18)), but not with reading ability at age 14. Socioeconomic position or other fixed maternal characteristics do not seem to explain the positive association between intrauterine growth and childhood intelligence.

    The mechanisms underlying the observed association of childhood intelligence with body mass index (BMI) are unclear and few studies of this association have been prospective in design. Prospective study in a birth cohort of 5467 individuals who were born in Aberdeen, Scotland between 1950 and 1956 and who responded to a follow-up survey in 2001. Comparison of associations within sibling pairs of the same family to associations between different families in 643 sibling pairs (1286 individuals) who are participants in the main cohort. Childhood intelligence (age 7 years) and educational attainment were both inversely associated with adult BMI (mean age 48 years): the sex- and age-adjusted mean change in adult BMI per s.d. of intelligence was -0.35 kg/m(2) (95% CI: -0.49, -0.21 kg/m(2)) and per unit increase in educational category (seven categories) was -0.28 kg/m(2) (95% CI: -0.34, -0.22). On adjustment for education the association between childhood intelligence and adult BMI attenuated to the null (-0.03 kg/m(2) (-0.19, 0.13 kg/m(2))); other potential confounding or mediating factors had little or only modest effects on this association. The association between education and adult BMI was not affected by adjustment for childhood intelligence or other potential covariates. The within sibling-pair effect of education on adult BMI (-0.06 kg/m(2) (95% CI: -0.26, 0.14)) was weaker than the effect between different families (-0.37 kg/m(2) (95%CI: -0.58, -0.17)), P-value for difference of within sibling and between family effect=0.03. The association of childhood intelligence with adult BMI is attenuated to the null on adjustment for educational attainment, whereas the association of educational attainment with adult BMI appears to be independent of childhood intelligence and other measured covariates. However, our family analyses suggest that fixed family and neighbourhood factors, which are closely matched in siblings of a similar age, explain much of the association

    2005-12-01

    This 3-wave, 5-year longitudinal study tested the contributions of family contextual factors and sibling relationship qualities to younger siblings' substance use, sexual risk behaviors, pregnancy, and sexually transmitted disease. More than 220 non-White families participated (67% Latino and 33% African American), all of which involved a younger sibling (133 girls and 89 boys; mean age = 13.6 years at Time 1) and an older sister (mean age = 17 years at Time 1). Results from structural equation latent growth curve modeling indicated that qualities of the sibling relationship (high older sister power, low warmth/closeness, and low conflict) mediated effects from several family risks (mothers' single parenting, older sisters' teen parenting, and family's receipt of aid) to younger sibling outcomes. Model results were generally stronger for sister-sister pairs than for sister-brother pairs. Findings add to theoretical models that emphasize the role of family and parenting processes in shaping sibling relationships, which, in turn, influence adolescent outcomes.

    Siblings adjust to having a brother or sister with a disability in diverse ways. This study investigated a range of child, parent and family factors as predictors of sibling adjustment outcomes. Forty-nine siblings (aged 7-16 years) and parents provided information about (1) sibling daily hassles and uplifts; (2) sibling coping; (3) parent stress; (4) parenting; and (5) family resilience. Multiple regression techniques were used. It was found that parent and family factors were stronger predictors of sibling adjustment difficulties than siblings' own experiences of stress and coping. Specifically, socio-economic status, past attendance at a sibling support group, parent stress, family time and routines, family problem-solving and communication, and family hardiness-predicted sibling adjustment difficulties. Finally, siblings' perceived intensity of daily uplifts significantly predicted sibling prosocial behaviour. The results revealed that the family level of risk and resilience factors were better predictors of sibling adjustment than siblings' own experiences of stress and coping resources, highlighting the importance of familial and parental contributions to the sibling adjustment process. The implications of these results for the design of interventions and supports for siblings are discussed.

    1982-01-01

    The sibling pairs from two different endothelial cell cultures were analysed by time-lapse cinematography. It was shown that wounded and regular (low density seeded) cultures differed in the behaviour patterns of their siblings. The cultures differed most significantly in the minimum interdivision time (IDT) which was 27% lower for the wounded culture. In the wounded culture there was a greater correlation of IDT values between sibling pairs. IDT values recorded both for paired and for unpaired cells were shorter for the wounded than for the regular culture. The mean IDT for unpaired cells was longer than the mean IDT for paired cells in the regular culture. Thus paired cells in the regular culture, had shorter IDTs, but not as short as in the wounded culture. It was significant that in the wounded culture the first generation of siblings were very close (less than 150 microns apart) at division. Overall the behaviour differences between the two cultures resulted in a higher rate of increase in cell numbers, and thus faster repair, of the wounded monolayer.

    2015-01-01

    In this article, we explore within-family differences in the closeness of sibling ties in adulthood. Specifically, we consider the sibship as a network and investigate the ways in which perceptions of mothers' differential treatment play a role in within-family variations in sibling closeness in midlife. Data were analyzed from 2,067 adult sibling dyads nested within 216 later life families, collected as part of the Within-Family Differences Study-II. Respondents reported the greatest closeness to siblings whom they perceived as favored by their mothers when they were not favored themselves, whereas respondents were less likely to choose siblings whom they perceived as disfavored by their mothers when they did not perceive themselves as disfavored. Variability in the strength of sibling ties within families suggests that some individuals receive greater benefits from this relationship than do their brothers and sisters. These findings shed new light on such within-family variations in sibling closeness by identifying how specific patterns of maternal differential treatment draw offspring toward some siblings and away from others. © The Author 2014.

    A family systems perspective directs attention to the potentially different experiences and perspectives of family members. This study examined parents' differential treatment (PDT) of siblings, discrepancies between parent and youth reports of PDT, and their links with relationships between adolescents and their mothers and fathers across three years. Participants were first- (Time 1 M age = 15.71, SD = 1.07) and secondborn (Time 1 M age = 13.18, SD = 1.29) siblings from 381, predominately white, working and middle class families. Analyses revealed that siblings' perceptions of being favored predicted less conflict with and greater warmth from both mothers and fathers, primarily for secondborn adolescents. Larger discrepancies between maternal and youth reports of differential affection were linked to more maternal conflict and less warmth for firstborns. These findings may suggest a hierarchy within families: parents may serve as referents for firstborns and firstborns as referents for secondborns.

    Primary familial hemophagocytic lymphohistiocytosis (HLH; or familial erythrophagocytic lymphohistiocytosis [FEL]) is a heterogeneous autosomal recessive disorder more prevalent with parental consanguinity. There is aggressive proliferation of activated macrophages and histiocytes, which phagocytose red blood cells (RBCs), white blood cells (WBCs), and platelets, leading to anemia, neutropenia and thrombocytopenia. The exaggerated response of immune system in familial HLH can occur in the abs...

    Ninety-six multiplex type I diabetic families were typed at the 5' flanking region of the insulin gene by using a PCR assay that better resolves the VNTR into multiple alleles. Affected sibling pairs shared 2, 1, and 0 VNTR alleles - identical by descent - at a frequency of .47, .45, and .08, respectively, a ratio that deviated from the expected 1:2:1 ratio (P<.001). These results confirm linkage of the chromosome 11p15.5 region with type I diabetes mellitus susceptibility. 20 refs., 2 tabs.

    Variability of age at onset (AO) of Alzheimer disease (AD) among members of the same family is important as a biological clue and because of its clinical effects. To evaluate which clinical variables influence the discrepancy in AO among affected relatives with familial AD. Clinical genetic project of Spanish kindred with AD conducted by 4 academic hospitals in Madrid, Spain. Age at onset of AD in 162 families and discrepancy in AO in intragenerational and intergenerational affected pairs were analyzed in relation to age, sex, maternal or paternal transmission, pattern of inheritance, and apolipoprotein E genotype. Maternal transmission of AD was significantly more frequent than paternal transmission (P patient was 65 years old. Discrepancy in AO among siblings was within 5 years in 44% of the families, 6 to 10 years in 29%, and more than 10 years in 27% (range, 0-22). This discrepancy was independent of the sex of the sibling pairs and was significantly lower with maternal transmission of AD (P = .02). Segregation analysis showed no differences in the inheritance pattern between families with low (5 years) AO discrepancy. Age at onset in carriers of the apolipoprotein E epsilon4 allele was slightly younger. However, among siblings, an extra apolipoprotein E epsilon4 allele was not consistently associated with earlier onset of AD. Eighty percent of patients, independent of sex or mode of transmission, were already affected at their parents' reported AO. There is a wide discrepancy in AO in affected siblings that is not clearly explained by a single clinical variable or apolipoprotein E genotype. The interaction of many factors probably determines AO in each affected individual. However, maternal transmission of AD seems to result in a similar AO in offspring, and the risk of developing dementia after the parent's reported AO decreases significantly.

    The identification of genes contributing to complex diseases and quantitative traits requires genetic data of high fidelity, because undetected errors and mutations can profoundly affect linkage information. The recent emphasis on the use of the sibling-pair design eliminates or decreases the likelihood of detection of genotyping errors and marker mutations through apparent Mendelian incompatibilities or close double recombinants. In this article, we describe a hidden Markov method for detect...

    Kirstilä, V; Sewón, L; Laine, J

    1993-06-01

    The periodontal status and treatment of three teenagers in a Finnish family with familial neutropenia is described. The mother was also diagnosed with neutropenia. At initial examination, the 15-year-old male and the 10-year-old female had severe periodontitis, whereas the 13-year-old male had oral ulcerations but no significant periodontal disease. The two siblings with periodontitis were treated and followed approximately 5 years. It was concluded that periodontal therapy including scaling, surgery, and use of antimicrobial agents can be successful in patients with familial neutropenia, and that such patients are not necessarily candidates for full mouth extraction. The role of granulocyte colony-stimulating factor in which was used in the treatment of these patients remains to be established.

    Family-Based Trauma-Focused Cognitive Behavioral Therapy with Three Siblings of a Refugee Family The possibility and relevance of a joint trauma-therapy with siblings has yet received little attention in research and clinical practice. The following case study presents a joint family-based trauma-focused therapy process with a refugee family. All three siblings suffered from post-traumatic stress disorder (PTSD) before treatment. The treatment followed the manual of Trauma Focused Cognitive Behavioral Therapy (TF-CBT; Cohen, Mannarino, Deblinger, 2009). Measures were the short version of the Child and Adolescent Trauma Screen (CATS 7-17), as well as the Teacher's Report Form (TRF). After 18 treatment sessions together with the mother, all three children did no longer meet PTSD criteria. Benefits of the joint therapy were for all three siblings to be sharing and imitating each other's coping strategies. Furthermore, the protective factor of social support after experiencing a traumatic event became evident. The apprehension of the therapist not being sufficiently neutral towards all three siblings was not observed.

    2015-11-01

    Sibling relationships have been described as love-hate relationships by virtue of their emotional intensity, but we know little about how sibling positivity and negativity operate together to affect youth adjustment. Accordingly, this study charted the course of sibling positivity and negativity from age 10 to 18 in African American sibling dyads and tested whether changes in relationship qualities were linked to changes in adolescents' internalizing and externalizing behaviors. Participants were consecutively-born siblings [at Time 1, older siblings averaged 14.03 (SD = 1.80) years of age, 48 % female; younger siblings averaged 10.39 (SD = 1.07) years of age, 52 % female] and two parents from 189 African American families. Data were collected via annual home interviews for 3 years. A series of multi-level models revealed that sibling positivity and sibling negativity declined across adolescence, with no significant differences by sibling dyad gender constellation. Controlling for age-related changes as well as time-varying parent-adolescent relationship qualities, changes in sibling negativity, but not positivity, were positively related to changes in adolescents' depressive symptoms and risky behaviors. Like parent-adolescent relationships, sibling relationships displayed some distancing across adolescence. Nevertheless, sibling negativity remained a uniquely important relational experience for African American adolescents' adjustment.

    The aim of this study was to describe a Neuman Systems Model-guided study of perceptions of family stressors experienced by adult siblings who share caregiving for their parents and the influence of these stressors on adult siblings' relationships. The task of providing informal care for disabled parents is often shared by adult siblings. Family stressors experienced as part of caregiving may affect the sibling relationship. A mixed-method study design was used. Data were collected during 2013-2014 from 84 adult sibling caregivers. Seventy-two caregivers provided quantitative data for the Lifespan Sibling Relationship Scale and the Zarit Burden Scale and 79 provided qualitative data for the open-ended question. Adult siblings experienced mild-to-moderate levels of burden from family stressors when they share parental caregiving. The amount of burden from intra-family stressors was negatively related to the adult sibling relationship. Beneficial and noxious stressors were evident in the participants' responses to an open-ended question. The health of the parents affected the lives of adult siblings in both negative and positive ways. Although the majority of the adult siblings expressed a willingness to care for their parent(s) in an attempt to reciprocate the care, they had received from them, challenges emerged from dealing with family stressors. © 2016 John Wiley & Sons Ltd.

    2009-01-01

    Siblings are important sources of social influence throughout childhood and adolescence. Nevertheless, the processes by which siblings influence one another remain relatively unexplored. We highlight two theories of sibling influence-sibling deidentification and social learning-that offer insights as to how and why siblings develop similar and different attributes, attitudes, and behaviors. Recognizing the need to move past post hoc explanations, we suggest several directions for how these two influence processes can be measured directly in future work. Research on sibling influence also can be improved by integrating these theories and attending to their domains of influence.

    Della Porta, Sandra; Howe, Nina

    2017-06-01

    This study examined sibling behavior during polyadic family conflicts (involving three or more family members) by identifying operational conflict elements (i.e., roles, topic), power strategies, effective influence of power, and social domain argumentation. Polyadic conflict sequences (n = 210) were identified in 35/39 families with two siblings (aged 4 and 6) and their parents observed at home. The dominant conflict topic, siblings' use of power and power strategy executed in relation to social domain argumentation, revealed unique qualities of conflict in the polyadic family context; effective use of power strategies to facilitate favorable outcomes differed by sibling birth order. Our account presents a nuanced view of the intricacies of polyadic family conflict, which provides unique opportunities for children's learning and socialization by siblings and parents. © 2017 Wiley Periodicals, Inc.

    2015-02-01

    The aim of this study was to investigate associations between maternal stress, parenting behavior, and sibling adjustment in relation to child trauma symptoms in families with and without a history of intimate partner violence (IPV). Maternal report was used to measure maternal stress and child trauma symptoms, whereas parenting behavior was assessed through an observational measure. Participants consisted of mothers with 2 school-age siblings recruited from the community. Results indicated that violent families reported higher levels of maternal stress and sibling trauma symptoms than nonviolent families, although no differences were found in parenting behavior. Sibling trauma symptoms and negative maternal behavior toward a sibling were strong predictors of trauma symptoms in younger siblings exposed to IPV but only modest predictors for older siblings. Moderator analyses showed that in IPV-affected families, the trauma symptoms of older siblings were related to the trauma symptoms of younger siblings when maternal stress was high.

  10. Sibling deidentification in the clinic: devil vs. angel.

    Science.gov (United States)

    Schachter, F F

    1985-09-01

    A four-member family structure consisting of two siblings contrasting in personality (sibling deidentification) and each identified with a different parent (split-parent identification) was recently reported (15). In well-functioning families, this tetrad or quadrangle is wide-spread in the first pair of siblings in the family and tends to be more common in same-sex pairs, suggesting that sibling deidentification is designed to mitigate the relatively intense sibling rivalry characteristic of these pairs and hence to maintain family harmony. In this collated case report, deidentification is found to follow the same pattern in 39 clinic first pairs. However, contrasting attributes are varied and nonevaluative in nonclinic pairs but mainly "good-bad" in clinic pairs, with polarization extreme. Results suggest that nonclinic siblings negotiate their identity (being) much as they negotiate about possessions (having) and that negotiations are blocked in clinic pairs, freezing mythic devil or angel identity. Intervention is directed at dislodging this block.

    To investigate the effect of sibling age, gender and dog ownership on children's independent mobility and how this varies according to the destination visited. Parents reported whether their child had an older sibling; if the child and older sibling were of the same gender; the number of older siblings; if they owned a dog; and whether their child was allowed to independently travel to school, friends' or family house, park/oval/sporting field and local shop. Data were analysed for 181 children aged 8-15 years. The strongest significant sibling effect for independently mobility to school, local shop and ≥3 destinations was for having an older sibling of the same gender (p≤0.05). For independent mobility to a friend's house and park, the strongest significant sibling effect was for having one older sibling (p≤0.05). Dog ownership was associated with increased odds of being independently mobile to ≥3 destinations (OR=2.43; 95%CI=1.03-5.74). Parents may be more likely to grant children licence to travel to local places if they are accompanied by an older sibling or the family dog. Understanding the effects of siblings and dog ownership on children's independent mobility will assist in identifying strategies through which independent mobility can be encouraged. © 2016 Public Health Association of Australia.

    2014-10-01

    It is estimated that more than 500 infants with Down syndrome (DS) are born each year in Korea. DS affects not only these individuals, but family members as well. Some siblings deal successfully with the challenges of living with a child with DS and adapt well while others struggle or fail to adapt. The aims of this descriptive study were to explore how Korean mothers of children with DS perceive the adaptation of their typically developing (TD) children aged 4 to 19 and how family variables contribute to sibling adaptation. This descriptive, cross-sectional study was conducted with 105 Korean mothers. Most mothers indicated that their TD children were not experiencing psychological or behavioural problems; however, many described problems in the sibling relationship. It was found that family factors (i.e. condition management effort, condition management ability, child's daily life, parental mutuality, family hardiness and social support) were strong predictors of sibling psychological, behavioural and relational adaptation. Demographic characteristics of the child with DS, the mother and the family appeared to significantly influence sibling adaptation. These findings highlight the importance of familial contexts in understanding sibling adaptation. Knowledge of family factors associated with better adaptation in Korean siblings of child with DS will facilitate the development of culturally appropriate interventions for these children and their families. In addition, an awareness of demographic characteristics associated with sibling adaptation will help health care professionals identify siblings who are at increased risk of experiencing difficulties in adapting. © 2014 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

    Communication within families of children with sickle cell disease is important yet has not been adequately investigated. Focus group interviews were conducted with parents of children with sickle cell disease to explore parent-sibling communication about sickle cell disease. Communication was influenced by attributes and behaviors of the parent, the child with sickle cell disease, and the sibling; extended family, neighbors, friends, and church members or social networks; and available, accessible resources related to the child's health, child's school, and parent employment. Outcomes that influenced and were influenced by factors within and outside the parent-sibling dyad and nuclear family included parent satisfaction, parent roles, family intactness, and status attainment. These findings support previous research with African-American families and expand our views of the importance of educating parents, family members, and others about sickle cell disease. The findings suggest a need to explore sibling perception of this communication, parent and sibling perception of the impact of frequent hospitalizations and clinic visits on the sibling and family, and variations within families of children with sickle cell disease.

    The authors studied sibling relationships of African American youths and family and youth characteristics linked to sibling dynamics. Participants were fathers, mothers, and 2 siblings (M = 14.04 and M = 10.34 years of age) from 172 working-middle class 2-parent families. Cluster analyses of data collected in home interviews revealed 3 sibling relationship types: positive, negative, and distant. Parent education was lower, parent religiosity higher, and parent-child relationships more positive in the positive group; maternal discrimination experiences were higher in the negative group; youth ethnic identity was stronger in the positive group; and youth depression and risky behavior were higher in the negative group. The findings target sociocultural factors to consider in interventions for African American families.

    2001-01-01

    In family therapy, during the last years more and more importance is attached to the dynamics of the sibling subsystem. In the present paper differences between them as well as similarities are discussed from the point of view of family theory. Relevant dimensions like support, attachment, rivalry and envy between brothers and sisters contribute essentially to the family dynamics. In this clinically orientated paper, we describe by means of a case example how the couple's conflicts after their separation is unconsciously repeated in the sibling subsystem. It is shown how the intergenerational dynamics can be interrupted by the initiative of the children and the initiated family therapy.

    Technology-dependent (TD) children require complex care and are dependent on medical technology. Approximately 75% of families, in the United States, who are caring for a TD child, also care for a well child. Well siblings are likely to be affected by the experience of living with a TD sibling as the process of family normalization is described as a family affair. The experiences of well siblings are not well described. The purpose of this qualitative analysis was to describe the experiences of well siblings who are living in a family with a TD child. Mothers were interviewed about the experiences of their well children and were digitally audio recorded. The interviews were transcribed, and content analysis was conducted. Content analysis from the interviews revealed the major themes of well sibling adjustment within the family unit, upside (altruistic, prosocial behaviors) and downside (negative internal and external processing behaviors). These results can be applied to advance the delivery of family nursing care offered to these families.

    2012-06-01

      Although many children grow up with more than one sibling, we do not yet know if sibling dyads within families show similarities to one another on sibling affection and hostility. In the present study the hypotheses were tested that (a) there will be significant between family variation in change in sibling affection and hostility and (b) this between family variation will be explained by maternal affective climate, operationalized as positive and negative ambient parenting, differential parenting and maternal malaise.   A general population sample of families with single and multiple sibling dyads were visited twice, 2 years apart. Up to 2 children in a family acted as informants; 253 relationships were rated in 118 families. A cross-classified, multilevel model was fit to separate between-family and within-family variance in sibling relationships while simultaneously controlling for informant and partner influences.   Thirty-seven percent of the variance in change in sibling affection and 32% of the variance in change in sibling hostility was between family variance. The measured maternal affective climate including, maternal malaise and maternal ambient and differential hostility and affection explained between family differences.   Sibling relationship quality clusters in families and is partly explained by maternal affective climate. © 2011 The Authors.

Within a period of six years, these three siblings (one girl and two boys) were diagnosed with Epstein-Barr virus (EBV)-positive Hodgkin lymphoma (HL). Methods: In......-situ hybridisation for EBV-encoded small nuclear RNAs 1 and 2 (EBER-ISH) was performed by standard non-isotopic technique. Germline mutation analysis was performed on peripheral blood lymphocytes. Results: Two of the siblings were diagnosed at age 12, the other at age 5. All three cases were localised at diagnosis i...... on peripheral blood samples of all family members (the five siblings and their parents) did not reveal germline mutations. None of the children had overt immunodeficiency or autoimmune disease. Conclusions: Genetic factors may be involved in HL. In fact, FHL cases may share HLA haplotypes and siblings...

    M.A. (Counselling Psychology) Sibling interaction is often an overlooked aspect of family functioning. For many years there has been an overemphasis on the importance of parental influences on children, yet common sense dictates that brothers and sisters must have some effect on each other even though this effect may not always be obvious. The sibling relationship is a life-long process, and is therefore highly influential throughout the life cycle ...

    Siblings share the same environment and thus potentially a substantial number of risk factors for child maltreatment. Furthermore, the number of siblings and the sibling constellation itself might pose a risk for child maltreatment. Little is known about the likelihood that more than one child in a family is maltreated and which factors increase the risk. This study sought to investigate similarities and differences in maltreatment in siblings and risk factors associated with the maltreatment of more than one child from the same family. Data on maltreatment during childhood and adolescence, family background, and sibling constellation were collected from 870 pairs of siblings. In the dyadic analyses, siblings reported similar maltreatment experiences, especially when any type of maltreatment was considered. Parents' mental health problems were significant predictors for maltreatment of at least one sibling. Father's mental health problems were predictive of maltreatment of both or only the younger sibling, mother's mental health problems of both or only the older sibling. Closeness in age and same gender of siblings did not emerge as a consistent predictor. The increasing number of siblings was a risk factor for any type of maltreatment of both siblings. The results highlight the need for preventive measures for families with a large number of children and with parents with mental health problems as well as a repeated risk assessment of all siblings in a family when one sibling was maltreated.

    Little is known about the involvement of siblings in family-based treatment (FBT) for anorexia nervosa (AN). To explore the experience of families, adolescents who had completed FBT, their siblings, and parents were interviewed. Siblings reported that involvement in FBT enhanced their understanding of anorexia and that they supported their family in various ways. While siblings often wished they had attended more sessions, there was no consensus among parents and patients regarding sibling attendance and many were concerned about potential negative impacts on siblings. Clinicians should discuss sibling roles and expectations early in FBT and work actively with families to address concerns.

    The authors examined siblings' reports of children's depression, anxiety, and aggression, and their reports of the sibling relationship, and compared them with children's self-reports. In two samples, including 169 sibling pairs (age M = 9.98 years, SD = 1.51), no significant differences emerged in the levels of depression and anxiety found in siblings' reports of children's behavior and children's self-reports, although siblings reported children to have significantly higher levels of aggression than the children self-reported. Age, the difference in ages between siblings, sex, and sibling sex were not related to siblings' reports of children's behavior. The relations between children's and siblings' reports of children's behavior were significant, yet moderate (average r = .22). Both siblings' self-reports of internalizing behavior and their perceptions of aspects of the sibling relationship (affection, rivalry, hostility, and satisfaction with the sibling relationship) explained significant, and unique, variance in siblings' reports of children's internalizing behavior. The findings for aggressive behavior were similar, although siblings' perceptions of affection in the sibling relationship were not significantly related to their reports of children's aggression. The potential uses and benefits of sibling reports of children's behavior, and sibling and family relationships, are discussed.

    Jealousy is a social emotion that has received little attention by developmental researchers. The current study examined sibling jealousy and its relations to child and family characteristics in 60 families with a 16-month-old toddler and an older preschool-age sibling. Sibling jealousy was elicited in social triads consisting of a parent (mother or father) and the two siblings. Positive marital relationship quality (i.e., love and relationship maintenance) was a particularly strong predictor of the older siblings' abilities to regulate jealousy reactions in the mother sessions. Younger siblings' jealous affect with mothers was linked to the child's temperament, whereas older siblings' jealous affect with mothers was related to the child's emotional understanding. Younger siblings displayed more behavioral dysregulation in the mother-sibling triads if there was greater sibling rivalry reported by mothers. Session order (i.e., which sibling was challenged first in the jealousy paradigm) had a strong effect on both the affect and behavioral dysregulation displayed by the older and younger siblings. Results are discussed with respect to the need for future research to consider social relationships as developmental contexts for young children's emotion regulation.

    Youth's experiences with romantic relationships during adolescence and young adulthood have far reaching implications for future relationships, health, and well-being; yet, although scholars have examined potential peer and parent influences, we know little about the role of siblings in youth's romantic relationships. Accordingly, this study examined the prospective longitudinal links between Mexican-origin older and younger siblings' romantic relationship experiences and variation by sibling structural and relationship characteristics (i.e., sibling age and gender similarity, younger siblings' modeling) and cultural values (i.e., younger siblings' familism values). Data from 246 Mexican-origin families with older (M = 20.65 years; SD = 1.57; 50 % female) and younger (M = 17.72 years; SD = .57; 51 % female) siblings were used to examine the likelihood of younger siblings' involvement in dating relationships, sexual relations, cohabitation, and engagement/marriage with probit path analyses. Findings revealed older siblings' reports of involvement in a dating relationship, cohabitation, and engagement/marriage predicted younger siblings' relationship experiences over a 2-year period. These links were moderated by sibling age spacing, younger siblings' reports of modeling and familism values. Our findings suggest the significance of social learning dynamics as well as relational and cultural contexts in understanding the links between older and younger siblings' romantic relationship experiences among Mexican-origin youth.

    In order to cope with the diagnosis of mental illness in a family member, siblings may be forced to adjust their roles in the family. Taking into account the crucial role that some siblings play in caregiving for the mentally ill especially when the parents are no longer available, it is imperative to develop awareness of their unique needs and address them. Thirty-three adult siblings of people diagnosed with a mental disorder completed the Role Behaviour Inventory (RBI) and a general questionnaire including open-ended questions regarding the roles they played in their families of origin. Findings from the inventory and general questionnaire suggest that the well siblings score higher on two roles, the Hero and Lost Child, and lower on the Mascot and Scapegoat roles relative to a comparison group (N = 33). Being a sibling caregiver emerged as a risk factor to assume certain dysfunctional roles in the family. Implications for future research and therapy are discussed. © 2013 International Union of Psychological Science.

    2016-01-01

    The following article provides an updated discussion on two Parse grounded exploratory descriptive studies in light to her recently added humanbecoming family model. The comments of the fathers and siblings from the studies reveal that family life is unpredictable and that family relationships are paradoxical evolutional emergences of shifting hopes and dreams. The humanbecoming family model provided a useful way to consider fathering and being a sibling, as unexpected unfoldings of joy-sorrow reveal purposeful new possibilities. It guides health professionals to avoid the imposition of their views on what is best for the family in favor of bearing witness to the suffering and disappointments that unfold in family life. It is important to remain open to families' sources of meaning, courage, and hope in the moment. © The Author(s) 2015.

    Raising a child with a disability (CWD) in the home is increasing across the globe. Because of caregiver burden and the complexity of care, there is growing concern for typically developing sibling (TDS) outcomes. The aim of the study was to examine whether caregiver burden, parenting style, and sibling relationships in families raising a CWD are associated with cooperative and externalizing behaviors in TDS. This correlational study included 189 families raising both a CWD and a TDS. Multilevel modeling was used to identify which variables were most predictive of TDS outcomes and if there were parent gender effects. Authoritative parenting was positively associated with cooperative behaviors. Authoritarian parenting was positively associated with externalizing behaviors. Multilevel modeling revealed caregiver burden was a significant predictor of sibling behaviors in the first model. When parenting style was added as a predictor, it was also significant. When sibling relationships were added as predictors, they were significant predictors for both cooperative and externalizing TDS behaviors; however, caregiver burden was no longer significant. Authoritarian parenting significantly predicted externalizing behaviors, and authoritative parenting was significantly related to cooperative behaviors. In families raising a CWD, positive sibling relationships may help negate the effects of caregiver burden and are more predictive of TDS outcomes than some parenting practices.

    Full Text Available Abstract Background Several family structure-related factors, such as birth order, family size, parental age, and age differences to siblings, have been suggested as risk factors for schizophrenia. We examined how family-structure-related variables modified the risk of schizophrenia in Finnish families with at least one child with schizophrenia born from 1950 to 1976. Methods We used case-sibling design, a variant of the matched case-control design in the analysis. Patients hospitalized for schizophrenia between 1969 and 1996 were identified from the Finnish Hospital Discharge Register, and their families from the Population Register Center. Only families with at least two children (7914 sibships and 21059 individuals were included in the analysis. Conditional logistic regression with sex, birth cohort, maternal schizophrenia status, and several family-related variables as explanatory variables was used in the case-sibling design. The effect of variables with the same value in each sibship was analyzed using ordinary logistic regression. Results Having a sibling who was less than five years older (OR 1.46, 95% CI 1.29–1.66, or being the firstborn (first born vs. second born 1.62, 1.87–1.4 predicted an elevated risk, but having siblings who were more than ten years older predicted a lower risk (0.66, 0.56–0.79. Conclusions Several family-structure-related variables were identified as risk factors for schizophrenia. The underlying causative mechanisms are likely to be variable.

    Siblings of children with disabilities are an important consideration for professionals working in family-centred contexts. Siblings of children with a disability often have unique experiences and insights that can assist understanding within family-centred interactions. In order to understand siblings' complex interactions with others in their lives, 676 contributions to a children's Internet sibling support site were analysed. Three themes arose from the inductive thematic analysis regarding siblings' interactions with strangers, peers, and their family. Identified subthemes (written from the perspective of the siblings) were as follows: Strangers stare and have negative attitudes towards my sibling with a disability; peers don't understand what it's like to be me, use certain words that upset me, say nasty things and tease me about my brother/sister; although my family loves me, they don't have a lot of time for me, our plans are often disrupted, and they give me a lot of responsibility. Within family-centred intervention it is recommended that health and education professionals, and parents assist siblings to build effective strategies for interacting with others others and learn from siblings' insights.

    In family-based treatment (FBT) for adolescent anorexia nervosa, all family members are encouraged to attend sessions with the understanding that absences negatively impact treatment. There are, however, many obstacles to family members' attendance, and there is no research to indicate whether family member attendance improves treatment outcomes. We examined attendance patterns of 198 families who participated in FBT at a specialist pediatric eating disorders program and assessed the extent to which participation by mothers (n = 194), fathers (n = 175), and siblings (n = 165; 50% female) predicted outcome. All mothers attended at least one session, and 74% attended all sessions. By comparison, 95% of fathers and 73% of siblings attended at least one session, and 33% of fathers and 1% of siblings attended all sessions. The mean proportion of sessions attended was 94% for mothers, 72% for fathers, and 20% for siblings. Over 6 months of treatment, the proportion of mothers who attended each session was largely stable; fathers' attendance declined slowly, and siblings' attendance declined more rapidly. Greater attendance by fathers predicted higher weight and lower eating disorder symptoms in adolescents at end of treatment. Remission at end of treatment was associated with higher attendance by fathers (M = 81% vs. M = 69%). Achieving sustained engagement of the whole family system in FBT is a considerable challenge. However, this study demonstrates that implementing processes that encourage and enable family members to attend treatment sessions could have significant benefits for patient outcomes.

    Guided by Bowen theory, we investigated the relationships between parent-child triangulation, parental differential treatment (PDT), sibling warmth, and individual depressive symptoms in a sample of 77 sibling dyads, aged 18-25 years, recruited through undergraduate classes at a U.S. public University. Results of the actor-partner interdependence models suggested that being triangulated into parental conflict was positively related to both siblings' perception of PDT; however, as one sibling felt triangulated, the other perceived reduced levels of PDT. For both siblings, the perception of higher levels of PDT was related to decreased sibling warmth and higher sibling warmth was associated with fewer depressive symptoms. The implications of these findings for research and the treatment of depression in the college-aged population are discussed. © 2016 American Association for Marriage and Family Therapy.

    2014-01-01

    Although the majority of families that experience intimate partner violence (IPV) have more than one child, most research to date has focused upon a single child within these families. A significant body of research has indicated siblings play an important role in children's adjustment and well-being. To address this gap, the three main goals of the present study were to compare the adjustment of older and younger siblings exposed to IPV, to describe and compare the quality of these sibling relationships from multiple perspectives, and to investigate how sibling adjustment and relationship quality influence children's adjustment. Forty-seven sibling pairs and their mothers were recruited from the community. Mothers self-reported on their violent experiences using the Conflict Tactics Scale, and also estimated the length of time their children were exposed to IPV. Mothers and children completed assessments of child adjustment and the quality of sibling relationships. Observers also assessed the quality of sibling interaction. Results indicated that adjustment between siblings was highly inter-related. On average, mothers reported sibling relationships as less positive but also as less hostile than did siblings themselves. Higher levels of sibling hostility, lower levels of sibling warmth and higher levels of disengagement each significantly predicted child adjustment; however, these effects were predicated upon the adjustment of the other sibling. The sibling relationships of children exposed to IPV made a difference in their individual adjustment, and their adjustment issues influenced how they feel about and interacted with their sibling. Sibling hostility played a stronger role in adjustment issues than sibling warmth. The nature of sibling influences and the direction of future research were discussed. Copyright © 2013 Elsevier Ltd.

    The vast variation in the role of childhood conditions for the education-mortality association may help us to further understand the interplay between family background, education, and mortality. The increase in the education gradient in suicide when siblings are compared may point towards individually oriented explanations (‘non-shared environment’, perhaps particularly in mental disorders, while shared family factors primarily seem to play a more important role in diseases in which health behaviors are most significant.

    2005-12-01

    This study investigated the family context of adolescent sibling similarity and differentiation in maladjustment (antisocial behavior and depression) by examining negativity in different subsystems. Two hypotheses were proposed: (1) Parental and sibling negativity tends to diffuse through the family system, especially because of the high level of reciprocity in sibling relationships, leading to sibling similarity; and (2) interparental (coparenting) conflict disrupts cohesive functioning and thereby motivates and facilitates sibling differentiation and niche picking. To control for the effects of similar genes between siblings, the authors used behavioral genetic models with a genetically informed sample of 720 two-parent families, each with at least 2 adolescent siblings. Results for the differences in shared environmental influences across groups high and low in each of the domains of family negativity provided partial support for the hypotheses. The results further understanding of influences on individual differences and support a theory of how parent-child and interparental relationships intersect with sibling relationship dynamics.

    2002-01-01

    In this study, similarities and differences in sibling relationships between children who have experienced family transitions and those who have not are examined. Comparisons are made between children who live in intact families, those whose parents have separated, and those who live in substitute care regarding the quality of their relationships with one of their siblings. More specifically, 4 dimensions describing the quality of sibling relationships are compared: Warmth/Closeness, Conflict, Relative Status/Power, and Rivalry (Furman & Buhrmester, 1985). The sample is made up of 3 groups of children (N = 158) aged between 8 and 12 years old: children living in intact families (n = 101), children who have experienced parental separation (n = 35), and children living in substitute care (n = 22). Results indicate differences on dimensions of Warmth/Closeness, Conflict, and Relative Status/Power. Different patterns of responses between the children who have experienced family transitions and those who have not are observed for the dimensions of Conflict and Power. The significant difference observed between the groups for the dimension of Warmth appears difficult to explain. Discussion of these results emphasizes the importance of the relationship between brothers and sisters experiencing family transition.

    The evolution of family life requires net fitness benefits for offspring, which are commonly assumed to mainly derive from parental care. However, an additional source of benefits for offspring is often overlooked: cooperative interactions among juvenile siblings. In this study, we examined how sibling cooperation and parental care could jointly contribute to the early evolution of family life. Specifically, we tested whether the level of food transferred among siblings (sibling cooperation) in the European earwig Forficula auricularia (1) depends on the level of maternal food provisioning (parental care) and (2) is translated into offspring survival, as well as female investment into future reproduction. We show that higher levels of sibling food transfer were associated with lower levels of maternal food provisioning, possibly reflecting a compensatory relationship between sibling cooperation and maternal care. Furthermore, the level of sibling food transfer did not influence offspring survival, but was associated with negative effects on the production of the second and terminal clutch by the tending mothers. These findings indicate that sibling cooperation could mitigate the detrimental effects on offspring survival that result from being tended by low-quality mothers. More generally, they are in line with the hypothesis that sibling cooperation is an ancestral behaviour that can be retained to compensate for insufficient levels of parental investment. © 2015 European Society For Evolutionary Biology.

    In this study we examined patterns of mothers' and fathers' differential affection and discipline toward 2 adolescent offspring in 243 Mexican-origin families. Grounding our work in a family systems perspective, we used interparental patterns of differential treatment as an index of the coparental alliance and tested their associations with parents' reports of familism values, traditional gender role attitudes, and cultural orientations. We also sought to replicate prior research on European American samples linking interparental patterns of differential treatment to marital qualities (coparenting satisfaction, love, and conflict) and adolescent depressive symptoms and risky behaviors. Three interparental patterns emerged: families in which both mothers and fathers treated their 2 offspring equally, incongruent families in which 1 parent treated both offspring equally while the other parent favored 1 offspring, and congruent families in which both parents favored the same offspring. Most parents reported equal treatment, but others fell into the incongruent affection (30%), incongruent discipline (45%), and congruent discipline (16%) groups. Mixed model analyses of variances revealed that in families in which mothers and fathers both treated their offspring equally, parents reported higher familism values, more traditional gender role attitudes, and relatively stronger orientations to Mexican than Anglo culture. Consistent with previous research, interparental incongruence was associated with less positive marital qualities and more adolescent adjustment problems. Discussion focuses on the role of culture in shaping coparenting and the processes through which these coparenting dynamics are linked to marital and youth adjustment.

    Self-identified lesbian, gay male, and bisexual (LGB) individuals were recruited via convenience sampling, and they in turn recruited their siblings (79% heterosexual, 19% LGB). The resulting sample of 533 heterosexual, 558 lesbian or gay male, and 163 bisexual participants was compared on mental health variables and their use of mental health services. Multilevel modeling analyses revealed that sexual orientation predicted suicidal ideation, suicide attempts, self-injurious behavior, use of psychotherapy, and use of psychiatric medications over and above the effects of family adjustment. Sexual orientation was unrelated to current psychological distress, psychiatric hospitalizations, and self-esteem. This is the 1st study to model family effects on the mental health of LGB participants and their siblings. Copyright (c) 2005 APA, all rights reserved.

    Sibling aggression among maltreated children placed in foster homes is linked to other externalizing problems and placement disruption. The reduction of sibling conflict and aggression may be achieved via a multicomponent ecologically focused intervention for families in the foster care system. The focus of the study is to evaluate the feasibility and short-term effectiveness of a transtheoretical intervention model targeting sibling pairs and their foster parent that integrates family systems, social learning theory, and a conflict mediation perspective. In this pilot study, sibling pairs (N = 22) and their foster parent were randomized into a three-component intervention (n = 13) or a comparison (n = 9) group. Promoting Sibling Bonds (PSB) is an 8-week prevention intervention targeting maltreated sibling pairs ages 5-11 years placed together in a foster home. The siblings, parent, and joint components were delivered in a program package at the foster agency by a trained two-clinician team. Average attendance across program components was 73 %. Outcomes in four areas were gathered at pre- and postintervention: observed sibling interaction quality (positive and negative) including conflict during play, and foster parent reports of mediation strategies and sibling aggression in the foster home. At postintervention, adjusting for baseline scores and child age, intervention pairs showed higher positive (p conflict during play (p conflict mediation strategies than those in the comparison group (p conflict and promote parental mediation, which together may reduce sibling aggression in the foster home.

    2013-07-01

    Previous research suggests adolescent alcohol use is largely influenced by environmental factors, yet little is known about the specific nature of this influence. We hypothesized that peer deviance and alcohol expectancies would be sources of environmental influence because both have been consistently and strongly correlated with adolescent alcohol use. The sample included 206 genetically related and 407 genetically unrelated sibling pairs assessed in mid-to-late adolescence. The heritability of adolescent alcohol use (e.g., frequency, quantity last 12 months) was minimal and not significantly different from zero. The associations among peer deviance, alcohol expectancies, and alcohol use were primarily due to shared environmental factors. Of special note, alcohol expectancies also significantly explained nonshared environmental influence on alcohol use. This study is one of few that have identified specific environmental variants of adolescent alcohol use while controlling for genetic influence.

    The E2F transcription factor family determines whether or not a cell will divide by controlling the expression of key cell-cycle regulators. The individual E2Fs can be divided into distinct subgroups that act in direct opposition to one another to promote either cellular proliferation or cell-cycle exit and terminal differentiation. What is the underlying molecular basis of this 'push-me-pull-you' regulation, and what are its biological consequences?

The authors report a family with two male siblings, 7 and 4 years old, affected by familial hyperchylomicronemia. The oldest was diagnosed at birth during evaluation of jaundice, and the youngest showed asymptomatic hypertriglyceridemia by 6 months of age. Due to high triglyceride levels, Gemfibrozil (a fibric acid derivative was started at diagnosis. Close clinical followup and laboratory monitoring of these children showed no side effects from the drug, and the risk of acute pancreatitis was significantly reduced.

    We characterized developmental outcomes of a large sample of siblings at familial high-risk of autism spectrum disorder (ASD), who themselves did not have ASD (n = 859), and low-risk controls with no family history of ASD (n = 473). We report outcomes at age 3 years using the Mullen Scales of Early Learning, the Autism Diagnostic Observation Schedule (ADOS), the Autism Diagnostic Interview-Revised (ADI-R) and adaptive functioning on the Vineland Adaptive Behavior Scales. Around 11% of high-risk siblings had mild-to-moderate levels of developmental delay, a rate higher than the low-risk controls. The groups did not differ in the proportion of toddlers with mild-to-moderate language delay. Thirty percent of high-risk siblings had elevated scores on the ADOS, double the rate seen in the low-risk controls. High-risk siblings also had higher parent reported levels of ASD symptoms on the ADI-R and lower adaptive functioning on the Vineland. Males were more likely to show higher levels of ASD symptoms and lower levels of developmental ability and adaptive behavior than females across most measures but not mild-to-moderate language delay. Lower maternal education was associated with lower developmental and adaptive behavior outcomes. These findings are evidence for early emerging characteristics related to the "broader autism phenotype" (BAP) previously described in older family members of individuals with ASD. There is a need for ongoing clinical monitoring of high-risk siblings who do not have an ASD by age 3 years, as well as continued follow-up into school age to determine their developmental and behavioral outcomes.

    Intellectual disability (ID) is a common neurodevelopmental disorder affecting 1-3% of the general population. Mutations in more than 10% of all human genes are considered to be involved in this disorder, although the majority of these genes are still unknown. We investigated 19 small non-consanguineous families with two to five affected siblings in order to identify pathogenic gene variants in known, novel and potential ID candidate genes. Non-consanguineous families have been largely ignored in gene identification studies as small family size precludes prior mapping of the genetic defect. Using exome sequencing, we identified pathogenic mutations in three genes, DDHD2, SLC6A8, and SLC9A6, of which the latter two have previously been implicated in X-linked ID phenotypes. In addition, we identified potentially pathogenic mutations in BCORL1 on the X-chromosome and in MCM3AP, PTPRT, SYNE1, and ZNF528 on autosomes. We show that potentially pathogenic gene variants can be identified in small, non-consanguineous families with as few as two affected siblings, thus emphasising their value in the identification of syndromic and non-syndromic ID genes.

    Patients with bipolar disorder from the US have more early-onset illness and a greater familial loading for psychiatric problems than those from the Netherlands or Germany (abbreviated here as Europe). We hypothesized that these regional differences in illness burden would extend to the patients siblings. Outpatients with bipolar disorder gave consent for participation in a treatment outcome network and for filling out detailed questionnaires. This included a family history of unipolar depression, bipolar disorder, suicide attempt, alcohol abuse/dependence, drug abuse/dependence, and "other" illness elicited for the patients' grandparents, parents, spouses, offspring, and siblings. Problems in the siblings were examined as a function of parental and grandparental problems and the patients' adverse illness characteristics or poor prognosis factors (PPFs). Each problem in the siblings was significantly (pUS than in those from Europe. In the US, problems in the parents and grandparents were almost uniformly associated with the same problems in the siblings, and sibling problems were related to the number of PPFs observed in the patients. Family history was based on patient report. Increased familial loading for psychiatric problems extends through 4 generations of patients with bipolar disorder from the US compared to Europe, and appears to "breed true" into the siblings of the patients. In addition to early onset, a variety of PPFs are associated with the burden of psychiatric problems in the patients' siblings and offspring. Greater attention to the multigenerational prevalence of illness in patients from the US is indicated. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available AbstractBackground: The association of attention-deficit/hyperactivity disorder (ADHD and tic disorder (TD is frequent and clinically important. Very few and inconclusive attempts have been made to clarify if and how the combination of ADHD+TD runs in families. Aim: To determine the first time in a large-scale ADHD sample whether ADHD+TD increases the risk of ADHD+TD in siblings and, also the first time, if this is independent of their psychopathological vulnerability in general. Methods: The study is based on the International Multicenter ADHD Genetics (IMAGE study. The present sub-sample of 2815 individuals included ADHD-index patients with co-existing TD (ADHD+TD, n=262 and without TD (ADHD-TD, n=947 as well as their 1606 full siblings (n=358 of the ADHD+TD index patients and n=1248 of the ADHD-TD index patients. We assessed psychopathological symptoms in index patients and siblings by using the strength and difficulties questionnaire (SDQ and the parent and teacher Conners’ long version Rating Scales (CRS. For disorder classification the Parental Account of Childhood Symptoms (PACS-Interview was applied in n = 271 children. Odds ratio with the GENMOD procedure (PROCGENMOD was used to test if the risk for ADHD, TD and ADHD+TD in siblings was associated with the related index patients’ diagnoses. In order to get an estimate for specificity we compared the four groups for general psychopathological symptoms.Results: Co-existing ADHD+TD in index patients increased the risk of both comorbid ADHD+TD and TD in the siblings of these index patients. These effects did not extend to general psychopathology. Interpretation: Co-existence of ADHD+TD may segregate in families. The same holds true for TD (without ADHD. Hence, the segregation of TD (included in both groups seems to be the determining factor, independent of further behavioral problems. This close relationship between ADHD and TD supports the clinical approach to carefully assess ADHD in

    1981-03-01

    Therapists traditionally view brothers and sisters as rivalrous and self-seeking. Under carefully arranged conditions, however, siblings can learn to cooperate with each other to resolve important conflicts in family relationships. This case documents a dramatic change in the relationship between a 29-year-old woman and her father, the outcome of a three-step therapeutic intervention in which sibling dynamics were selectively used by the psychotherapist. As part of her individual therapy, the therapist first aroused the woman's discontent with her status as the neglected "baby of the family." Next, a series of meetings were held with the woman and her three sisters that permitted resolution of their previous anger and misunderstandings, thus helping them to become a more cohesive group of sisters. The third step brought the sisters, now as allies both of the identified patient and of the therapist, into a constructive confrontation with the parents. This resulted in lasting personal change for the identified patient and improved relationships throughout the entire family.

    Parents' differential treatment (PDT) is a common family dynamic that has been linked to youth development and well-being, including adjustment problems and poor sibling relationships. Much less is known, however, about the developmental course of PDT and the conditions under which parents treat their children differently in adolescence and young adulthood. This study examined longitudinal changes in mothers' and fathers' differential warmth and conflict with their two offspring from early adolescence through young adulthood and examined parents' experiences of individual stress (depressive symptoms and role overload) and marital difficulties as time-varying correlates of (changes in) PDT. We also tested crossover effects to determine whether mothers' experiences of individual stress and marital difficulties were linked to fathers' differential treatment, and vice versa. Participants were mothers, fathers, and two siblings from 246 Mexican-origin families who were interviewed in their homes on three occasions over 8 years. Multilevel models revealed that mothers' and fathers' differential conflict with their two children increased until middle adolescence and then declined into young adulthood, but there were no changes over time for parents' differential warmth. In general, both mothers' and fathers' levels of differential treatment were exacerbated by their own experiences of individual stress and marital difficulties and also by the experiences of their spouses. However, in some cases, greater stress than usual was linked to less differential treatment than usual. © 2017 Family Process Institute.

    2014-02-01

    Older and younger siblings occasionally attempt to impersonate parent and child to expedite immigration under US family-based visa policies. The rate with which full siblings escape detection by current relationship tests is unknown. Retrospective study of full-sibling immigrant pairs was undertaken to determine the proportion that show insufficient genetic evidence to exclude parentage. Sibship and parentage indices (SI and PI) were compared/case in unexcluded sibling cases and true parent-child cases. Alleles shared per short-tandem-repeat locus were compared in sibling and parent-child pairs. The proportion of successful parentage fraud by siblings was estimated from the parentage exclusion rate among immigrants and the proportion of sibships without genetic inconsistencies (GIs). When 11 to 25 independent loci were tested per two-sibling case to verify or refute parentage, tests failed to demonstrate any GI in 9% and PI was greater than SI in seven of 10 of these cases. Another 29% of full-sibling pairs demonstrated insufficient evidence (fewer than two GIs) to exclude parentage. Thus, 0.4% of sibling pairs could falsely claim a parent-child relationship and show no GIs. Another 1.4% could make that false claim and not present sufficient evidence to be excluded. At present, with no evidence of parentage exclusion in a full-sibling pair, the relative magnitudes of PI and SI are misleading relationship indicators because too few loci are examined and rates of sharing one and two alleles/locus vary greatly in parentage and sibling pairs. Only evidence of exclusion ascertains false parentage claims by siblings. Nevertheless, the expected rate of successful fraud is quite low. © 2013 American Association of Blood Banks.

    Macaulay, Catrin E; Ford, Ruth M

    2013-10-01

    We evaluated the cognitive development of 48 profoundly deaf children from hearing families (born 1994-2002, mean age M = 8.0 years at time of test, none of whom had received early auditory-verbal therapy) as a function of family socioeconomic status and number of siblings. Overall, the deaf children matched a younger group of 47 hearing controls (M = 4.6 years) on verbal ability, theory of mind, and cognitive inhibition. Partial correlations (controlling for age) revealed positive relations in the hearing group between maternal education and inhibition, between number of younger siblings and references to emotions, and between number of close-in-age siblings and references to desires and false beliefs. In the deaf group, there were positive relations between household income and memory span, between maternal education and references to false beliefs, and between number of younger siblings and nonverbal ability. In contrast, deaf children with a greater number of older siblings aged ≤12 years showed inferior memory span, inhibition, belief understanding, picture-sequencing accuracy, and mental-state language, suggesting that they failed to compete successfully with older siblings for their parents' attention and material resources. We consider the implications of the findings for understanding birth-order effects on deaf and language-impaired children.

    Genetic factors have been found to influence the risk of suicide. It is less clear if this also applies to attempted suicide. We have investigated genetic and familial environmental factors by studying the occurrence of suicide attempts in biological and adoptive siblings of adoptees who attempted suicide compared to siblings of adoptees with no suicide attempts. We used a random sample of 1933 adoptees from the Danish Adoption Register, a register of non-familial adoptions of Danish children, i.e. the adoptive parents are biologically unrelated to the adoptee. Analyses were conducted on incidence rates of attempted suicide in biological and adoptive siblings given occurrence of attempted suicide in the adoptees while also taking into account psychiatric disorders. Information about suicidal attempt and history of psychiatric disorder was based on hospital admissions. The rate of attempted suicide in full siblings of adoptees who attempted suicide before age 60 years was higher than in full siblings of adoptees who had not attempted suicide (incidence rate ratios (IRR)=3.45; 95% confidence interval [CI]=0.94-12.7). After adjustment for history of psychiatric admission of siblings the increased rate was statistically significant (IRR=3.88; 95% CI-1.42-10.6). Information on attempted suicide and psychiatric history was limited to that which involved hospitalisation. Genetic factors influence risk of suicide attempts. © 2013 Published by Elsevier B.V.

    This study builds on the scant research involving siblings of children with severe emotional disturbances (SED) and examines: associations between adversity experiences and adjustment among 5- to 10-year-old siblings, and relations among family resources, community life, and sibling adjustment. Caregivers from 100 families completed standardized indicators of sibling adjustment and scales reflecting multiple contextual variables. Results document negative associations between stress exposure and sibling adjustment. Regression models also indicate positive associations between the caregiver-child relationship and broader family resources on sibling behavioral and emotional strengths, even after accounting for adversity experiences; adversity exposure was the prime correlate in regression models involving sibling oppositional behavior. Analyses also suggest that strain related to parenting a child with SED is associated with sibling adjustment. This work documents the needs of these siblings and their family systems and highlights the relevance of not only core proximal influences (e.g., child-caregiver relationship) but also elements of their broader contexts. Implications and recommendations are described, including the need to support plans of care that involve services, supports, or preventive strategies for these siblings. © 2010 American Orthopsychiatric Association.

    The purpose of this study is to find out if the personalities of siblings are similar or different. Subjects used were Doshisha University students and members of their families, provided those families had only two children. Altogether 29 pairs of boys and their younger brothers, 47 pairs of boys and their younger sisters, 44 pairs of girls and their younger brothers, and 51 pairs of girls and their younger sisters were given the MMPI individually. Sibling status effects were found in many of the MMPI scores according to the type of sibling dyads and birth order, especially for the sibling dyad of elder brother and younger sister. Personality relationships between the first and second child showed that there were significant correlations in many MMPI scales: L, K, Pd, Pa, Pt, Sc, Si, Conflict resolution, Manifest anxiety, Repression-Sensitization, and Hostility. Among the four types of sibling dyad, the pairs of girls and their younger brothers showed the highest correlation in their personality.

    We compared the nature of the sibling relationship in dyads of varying genetic relatedness, employing a behavioural genetic design to estimate the contribution that genes and the environment have on this familial bond. Two samples were used-the Sisters and Brothers Study consisted of 173 families with two target non-twin children (mean ages = 7.42 and 5.22 years respectively); and the Twins, Family and Behaviour study included 234 families with two target twin children (mean age = 4.70 years). Mothers and fathers reported on their children's relationship with each other, via a postal questionnaire (the Sisters and Brothers Study) or a telephone interview (the Twins, Family and Behaviour study). Contrary to expectations, no mean level differences emerged when monozygotic twin pairs, dizygotic twin pairs, and non-twin pairs were compared on their sibling relationship quality. Behavioural genetic analyses also revealed that the sibling bond was modestly to moderately influenced by the genetic propensities of the children within the dyad, and moderately to substantially influenced by the shared environment common to both siblings. In addition, for sibling negativity, we found evidence of twin-specific environmental influence-dizygotic twins showed more reciprocity than did non-twins. Our findings have repercussions for the broader application of results from future twin-based investigations.

  7. Family Complexity and the Stress Process in Prison: How Sibling Living Arrangements of Minor Children Influence Maternal Role Strains

    Full Text Available This paper offers a life-course stress process perspective on maternal role strain as a ‘pain of imprisonment’ by engaging the concept of ‘family complexity’ in the context of mass incarceration I consider how the living arrangements of minor siblings (i.e., those living apart or together during maternal incarceration functions as a form of family complexity. When minor children live apart from their siblings, they may experience more isolation which may further serve as a stressor for incarcerated mothers. A positive association between siblings living apart and maternal role strain would support a process of ‘stress proliferation’ across the prison-family interface. I investigate these connections using survey-based data on mothers with multiple minor children (n = 80 collected in 2011 from a voluntary sample of respondents housed in a federal minimum security prison in the United States. Multivariate logistic regression results indicate that minor siblings living apart during periods of maternal confinement elevates role strain among mothers (odds ratio = 3.66, p < 0.05. This connection is indicative of an ‘inter-institutional strain.’ Finally, children’s age also increases maternal role strain, but this finding is explained by sibling living arrangements during the mother’s incarceration.

    The occurrence of autoimmune hemolytic anemia and immune thrombocytopenia in the absence of a known underlying cause led to the diagnosis of Evans syndrome in a 9 month old male. Subsequently, a similar diagnosis was made in two siblings (a 3 year old boy and a 1 day old girl). The 9 month old had a chronic course with exacerbations. He was treated with steroids, intravenous immunoglobulin and colchiccine with a variable response. He died of congestive heart failure at the age of 8 years. The brother's disease course was one of remission and exacerbation. With time, remissions were prolonged and paralleled an improvement in joint hypermobility. The sister died of sepsis after a chronic course with severe exacerbattions. Only two families with Evans syndrome have been reported in the English medical literature. In one report (in a Saudi Arab family), the disease was associated with hereditary spastic paraplegia. (author)

    Children with siblings coping with chronic illness experience stresses and disruptions in daily life as families work together to care for the affected child. Research suggests that children and adolescents with sickle cell disease (SCD) may be at risk for adjustment problems, impaired psychosocial functioning, and reduced quality of life. These potential stressors affect the child with SCD as well as their caregivers and other family members. This study examined the role of family functioning on the psychosocial functioning of healthy siblings of children with SCD. Participants were 65 healthy African-American siblings of children with SCD with a mean age of 11.19 years (range: 7-16) and their primary caregiver. Caregivers completed questionnaires assessing family functioning and child adjustment including demographic surveys, the Family Relations Scale (FRS), and the Child Behavior Checklist (CBCL). Increased number of emergency room visits (β = -0.28, P Family functioning mediated this effect (β = 0.27; P family expressiveness (total score, r = -0.34; P family conflict (total score, r = 0.41; P family expressiveness, support, and conflict are indicated for this population.

    Insects rely more on chemical signals (semiochemicals) than on any other sensory modality to find, identify, and choose mates. In most insects, pheromone production is typically regulated through biosynthetic pathways, whereas pheromone sensory detection is controlled by the olfactory system. Orchid bees are exceptional in that their semiochemicals are not produced metabolically, but instead male bees collect odoriferous compounds (perfumes) from the environment and store them in specialized hind-leg pockets to subsequently expose during courtship display. Thus, the olfactory sensory system of orchid bees simultaneously controls male perfume traits (sender components) and female preferences (receiver components). This functional linkage increases the opportunities for parallel evolution of male traits and female preferences, particularly in response to genetic changes of chemosensory detection (e.g. Odorant Receptor genes). To identify whether shifts in pheromone composition among related lineages of orchid bees are associated with divergence in chemosensory genes of the olfactory periphery, we searched for patterns of divergent selection across the antennal transcriptomes of two recently diverged sibling species Euglossa dilemma and E. viridissima. We identified 3185 orthologous genes including 94 chemosensory loci from five different gene families (Odorant Receptors, Ionotropic Receptors, Gustatory Receptors, Odorant Binding Proteins, and Chemosensory Proteins). Our results revealed that orthologs with signatures of divergent selection between E. dilemma and E. viridissima were significantly enriched for chemosensory genes. Notably, elevated signals of divergent selection were almost exclusively observed among chemosensory receptors (i.e. Odorant Receptors). Our results suggest that rapid changes in the chemosensory gene family occurred among closely related species of orchid bees. These findings are consistent with the hypothesis that strong divergent selection

    Few studies have examined changes in siblings after the death of a brother or sister, particularly from mother, father, and sibling perspectives within the first year after death. This descriptive study identified and assessed the frequency of changes in siblings after a child's death from cancer. Participants were recruited from cancer registries at 3 hospitals in the United States and Canada 3 to 12 months after the child's death. Thirty-six mothers, 24 fathers, and 39 siblings from 40 families were included. Semistructured interviews using open-ended questions were conducted with each parent and sibling separately in the home. Content analysis identified emerging themes, and the McNemar tests compared frequencies between each paired set of reports (sibling vs mother, sibling vs father, mother vs father). Sixty-nine percent of participants reported personal changes in siblings (eg, changes in personality, school work, goals/life perspective, activities/interests). Forty-seven percent noted changes in siblings' relationships with family members and peers. Only 21% of participants reported no changes attributed to the death. Comparisons of frequencies across informants were not significant. Most siblings experienced changes in multiple areas of their lives after the death of a brother or sister to cancer. Some changes reflected siblings that were positively adapting to the death, whereas other changes reflected difficulties. Our findings offer guidance to improve aftercare for bereaved siblings and their families. Additional research is needed to further delineate the needs of bereaved siblings and to develop strategies to promote adaptation to loss.

    Multimorbidity may impose an overwhelming burden on patients with psychosis and is affected by gender and age. Our aim is to study the independent role of familial liability to psychosis as a risk factor for multimorbidity. We performed the study within the framework of the Genetic Risk and Outcome of Psychosis (GROUP) project. Overall, we compared 1024 psychotic patients, 994 unaffected siblings and 566 controls on the prevalence of 125 lifetime diseases, and 19 self-reported somatic complaints. Multimorbidity was defined as the presence of two or more complaints/diseases in the same individual. Generalized linear mixed model (GLMM) were used to investigate the effects of gender, age (adolescent, young, older) and familial liability (patients, siblings, controls) and their interactions on multimorbidity. Familial liability had a significant effect on multimorbidity of either complaints or diseases. Patients had a higher prevalence of multimorbidity of complaints compared to siblings (OR 2.20, 95% CI 1.79-2.69, Psiblings, had significantly higher prevalence than controls. Similar finding were observed for multimorbidity of lifetime diseases, including psychiatric diseases. Significant results were observed for complaints and disease multimorbidity across gender and age groups. Multimorbidity is a common burden, significantly more prevalent in patients and their unaffected siblings. Familial liability to psychosis showed an independent effect on multimorbidity; gender and age are also important factors determining multimorbidity. Copyright © 2017 Elsevier Masson SAS.

    Dyads of siblings in which the younger sibling had an intellectual disability (ID, n  =  25) were videotaped interacting. The ID group was compared with typically developing sibling dyads matched on mental age (n  =  25) and chronological age (n  =  25). We observed the mediation strategies, activation, and antimediation behaviors of older siblings and younger siblings' responsiveness to mediation. Mediation strategies were analyzed by the Observation of Mediation Interaction scale. The ID group scored highest on mediation strategies and lowest on activation and antimediation behaviors. Younger siblings' responsiveness to mediation was highest among the ID group. Mediation for Intentionality and Reciprocity and Meaning were positively associated with the verbal responsiveness of the younger siblings. Activation and antimediation behaviors were negatively associated with the verbal responsiveness.

    Full Text Available Abstract Background Various indicators of childhood socioeconomic position have been related to cardiovascular disease (CVD risk in adulthood. We investigated the impact of shared family factors on the educational gradient in midlife CVD risk factors by assessing within sibling similarities in the gradient using a discordant sibling design. Methods Norwegian health survey data (1980–2003 was linked to educational and generational data. Participants with a full sibling in the health surveys (228,346 individuals in 98,046 sibships were included.

Results Educational gradients in risk factors were attenuated when factors shared by siblings was taken into account: A one category lower educational level was associated with 0.7 (95% confidence interval 0.6 to 0.8 mm Hg higher systolic blood pressure (27% attenuation, 0.4 (0.4 to 0.5 mmHg higher diastolic blood pressure (30%, 1.0 (1.0 to 1.1 more beats per minute higher heart rate (21%, 0.07 (0.06 to 0.07 mmol/l higher serum total cholesterol (32%, 0.2 (0.2 to 0.2 higher smoking level (5 categories (30%, 0.15 (0.13 to 0.17 kg/m2 higher BMI (43%, and 0.2 (0.2 to 0.2 cm lower height (52%.

Conclusion About one third of the educational gradients in modifiable CVD risk factors may be explained by factors that siblings share. This implies that childhood environment is important for the prevention of CVD.

  1. Intergenerational transfers and European families: Does the number of siblings matter?

    2013-08-01

    Full Text Available BACKGROUND Existing research on intergenerational transfers has focused on income and wealth as the predominant determinants of the provision of financial assistance to adult children (Albertini, Kohli, and Vogel 2006; Zissimopoulos and Smith 2010; Albertini and Radl 2012. Yet previous models of intergenerational transfers underestimated the effect of family size due to the effect of birth order and inappropriate research design. OBJECTIVE This paper aims to more accurately describe the relationship between family size and intergenerational financial transfers in Europe. In developing a more appropriate theoretical and empirical understanding of intergenerational behaviour by borrowing findings from other areas of family studies, this paper explores the issues involved in the complex analysis of cross generational issues such as sampling, diverse and complex family forms, and unobserved family- and individual-level heterogeneity. METHODS Using multilevel methods to nest individual children in their extended families, this paper analyses data from the Survey for Health, Ageing and Retirement in Europe, and concludes that family size and birth order are essential for understanding intergenerational transfers. Logit and Tobit models are used to predict transfer occurrence and amount, and therefore avoid bias estimates found with OLS in existing research. RESULTS The analysis suggests that an only child is more than four times as likely to receive financial assistance as someone in a four-child family. This means that the maximum effect of family size is more than twice that of parental income. A separate and independent effect of birth order is also identified, which suggests that the oldest in a four-child family is twice as likely to receive financial assistance as their youngest sibling. CONCLUSIONS The policy implications of this finding are significant in the context of an ageing society and demographic change, suggesting a shift in focus from

    To evaluate the impact of a family-oriented inpatient rehabilitation programme on behavioural and emotional problems in healthy siblings of chronically ill children and to assess the association between these problems and quality of life. A total of 259 healthy children (4-16 years, M = 8.6 years, SD = 3.3) with a chronically ill sibling were enrolled in the study. Parents filled in the Strengths and Difficulties Questionnaire, while the children answered a self-report quality of life instrument (LQ-KID) at the time of admission and discharge from the clinic and at a 6-month follow-up. Comparisons were performed with a matched control group from the German general population (n= 777). Significant behavioural or emotional symptoms were found in 30.5% of the healthy siblings, the relative risk of having elevated scores being 2.2 compared with the control group. Symptoms were inversely correlated with quality of life (r=-0.42). During the inpatient rehabilitation, symptoms decreased significantly to a normal level. Similarly, quality of life significantly improved, except in the dimension family relations. Family-oriented inpatient rehabilitation is a promising approach to improve the mental health of children with a chronically ill sibling.

    To assess the role of oxidized phospholipids (OxPLs) in children with familial hypercholesterolemia (FH) and the effect of pravastatin. Oxidized phospholipids are a major component of oxidized low-density lipoprotein (OxLDL) and are bound to lipoprotein (a) [Lp(a)]. The significance of OxPL markers in children is unknown. Children with FH were randomized to placebo (n = 88) or pravastatin (n = 90) after instruction on American Heart Association step II diet. Unaffected siblings (n = 78) served as controls. The OxPL content on apolipoprotein B-100 (apoB) detected by antibody E06 (OxPL/apoB ratio), immunoglobulin (Ig)G and IgM immune complexes per apoB (IC/apoB) and on all apoB particles (total apoB-IC = IC/apoB multiplied by plasma apoB levels), autoantibodies to malondialdehyde (MDA)-low-density lipoprotein (LDL), Lp(a), and apoB levels were measured at baseline and after two years of treatment. Compared with unaffected siblings, children with FH had significantly lower levels of OxPL/apoB but higher levels of IgG and IgM total apoB-IC and IgM MDA-LDL autoantibodies. From baseline to two-year follow-up, compared with placebo pravastatin treatment resulted in a greater mean percentage change in apoB (-18.7% vs. 0.3%; p = 0.001), total IgG apoB-IC (-31.9% vs. -12.2%; p vs. 13.2%; p = 0.001). Interestingly, pravastatin also resulted in higher OxPL/apoB (48.7% vs. 29.3%; p = 0.028) and Lp(a) levels (21.9% vs. 10.7%; p = 0.044). Compared with unaffected siblings, children with FH are characterized by elevated levels of apoB-IC and IgM MDA-LDL autoantibodies. Compared with placebo, pravastatin led to a greater reduction in apoB-IC but also to a greater increase in OxPL/apoB and Lp(a), which may represent a novel mechanism of mobilization and clearance of OxPL.

    A family of tridiagonal pairs which appear in the context of quantum integrable systems is studied in detail. The corresponding eigenvalue sequences, eigenspaces and the block tridiagonal structure of their matrix realizations with respect the dual eigenbasis are described. The overlap functions between the two dual bases are shown to satisfy a coupled system of recurrence relations and a set of discrete second-order q-difference equations which generalize those associated with the Askey-Wilson orthogonal polynomials with a discrete argument. Normalizing the fundamental solution to unity, the hierarchies of solutions are rational functions of one discrete argument, explicitly derived in some simplest examples. The weight function which ensures the orthogonality of the system of rational functions defined on a discrete real support is given

    There are limited data on the outcome of patients with thalassemia receiving HSCT from non-sibling matched family donors. Of the 341 patients with thalassemia major that underwent donor search at our center from January 2003 to December 2011, 236 (69.2%) had fully matched family donor of which 28 patients (8.2%) had non-sibling matched family donors identified. We report on seven patients with a median age of eight yr (4-21) who underwent myeloablative (n = 4) or RIC (n = 3) HSCT. The median age of the donors was 33 yr (4-47), three were parents, two first cousins, one paternal uncle, and one paternal aunt. All patients achieved primary neutrophil and platelet engraftment at a median of 18 (13-20) and 16 days (11-20), respectively. One patient developed grade II acute GVHD, and two patients developed limited chronic GVHD. One patient experienced secondary GF requiring a second transplant. At a median follow-up of 69 months (7-110), all patients are alive and thalassemia free. Our data emphasize the need for extended family HLA typing for patients with thalassemia major in regions where there is high rate of consanguinity. Transplant from non-sibling matched family donor can result in excellent outcome. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Family-centered burial practices influence cemetery structure and can represent social group composition in both modern and ancient contexts. In ancient sites dental phenotypic data are often used as proxies for underlying genotypes to identify potential biological relatives. Here, we test the performance of deciduous dental morphological traits for differentiating sibling pairs from unrelated individuals from the same population. We collected 46 deciduous morphological traits for 69 sibling pairs from the Burlington Growth Centre's long term Family Study. Deciduous crown features were recorded following published standards. After variable winnowing, inter-individual Euclidean distances were generated using 20 morphological traits. To determine whether sibling pairs are more phenotypically similar than expected by chance we used bootstrap resampling of distances to generate P values. Multidimensional scaling (MDS) plots were used to evaluate the degree of clustering among sibling pairs. Results indicate an average distance between siblings of 0.252, which is significantly less than 9,999 replicated averages of 69 resampled pseudo-distances generated from: 1) a sample of non-relative pairs (P < 0.001), and 2) a sample of relative and non-relative pairs (P < 0.001). MDS plots indicate moderate to strong clustering among siblings; families occupied 3.83% of the multidimensional space on average (versus 63.10% for the total sample). Deciduous crown morphology performed well in identifying related sibling pairs. However, there was considerable variation in the extent to which different families exhibited similarly low levels of phenotypic divergence. © 2015 Wiley Periodicals, Inc.

    Full Text Available Parental differential treatment is an important feature of non-shared family environment which contributes to the development of behavioural differences between siblings growing up in the same family. To investigate the frequency, direction, and patterns of parental differential treatment of siblings in Slovene families, mothers and fathers of 93 sibling-pairs in early/middle childhood provided self-reports in a two-wave longitudinal study. Most of the parents reported on low levels of differential treatment, predominantly expressing somewhat more affection and control towards the older than towards the younger sibling. Over a one-year time period, the average frequency of parental differential treatment did not change significantly, whereas the stability was estimated as moderate for maternal and low for paternal assessments. Maternal and paternal self-ratings were moderately correlated. However, the mothers reported on somewhat higher levels of differential control and (only in wave 1 affection than the fathers. Nearly half of the families were characterized by a congruent pattern of parental differential treatment indicating that both parents showed more affection and control towards the older of the two siblings. A complementary family pattern reflecting an opposite direction of maternal and paternal differential treatment emerged in approximately a quarter of the participating families.

    To evaluate similarities and differences in visual function and ocular structure between siblings with albinism. The medical records of all siblings diagnosed with albinism were retrospectively reviewed. Comparisons were made using examination at oldest age for younger sibling and examination closest to that age for older siblings. A total of 111 patients from 54 families were studied. Mean age was 12.9 years (range, 2 months to 44.2 years). Mean difference in ages between sibling pair examinations was 11.5 months (range, 0-87 months). Of 45 families, best-corrected visual acuity was equal in 9 (20%), within 1/2 octave in 9 (20%), >1/2 but albinism should be counseled with due caution because visual function is often disparate despite similar structural findings.

    Full Text Available This study exploits the sibling structure of the National Longitudinal Survey of Youth data to measure the degree to which family background explains the variance in the propensity to engage in criminal activities and in the intensity and success of crime participation as measured by the level of criminal earnings. A multiple-equation model whose reduced form disturbances are connected by a common unobservable variable having a variance-components structure is developed and estimated. Estimation results indicate a high level of association (net of observable measures of family background between the unobserved factors affecting siblings' propensity to engage in criminal activities in a family, with estimated intra-family correlations ranging from 0.44 to 0.55. Sharing a common family background explains around 25% of the variance of the unconditional criminal income. The results suggest that ignoring family background effects leads to a significant upward bias in the effects of race and education on the propensity to engage in income-generating crime.Este estudo usa dados do National Longitudinal Survey of Youth para medir a extensão pela qual interações sociais de família explicam a variância na probabilidade de participação em crime e na intensidade e sucesso em atividades criminais. A estimação é baseada em um mo-delo de equações múltiplas cujas perturbações são interligadas por uma variável inobservável comum. A virtude do método proposto é usar dados referentes a irmãos - que compartilham as mesmas características maternas e paternas em relação a fatores de família que possivelmente influenciam a sua própria decisão de engajar em atividades ilegais - para estimar o efeito do background familiar na decisão de participar em crime. Os resultados empíricos indicam um alto nível de correlação entre fatores inobserváveis medindo efeitos de família e a propensão de irmãos em participar de atividades criminosas

    Parents are often concerned about repeated conflicts between their daughters and sons. However, there is little empirical research of sibling bullying. To conduct a review of existing studies of sibling bullying. Are there any associations between sibling bullying and peer bullying at school? What are the consequences of sibling bullying? Is there good justification why sibling bullying has been so neglected in research? Studies of sibling relationships were reviewed. Four quantitative studies were identified that report on both sibling and peer bullying. Sibling bullying is frequent with up to 50% involved in sibling bullying every month and between 16% and 20% involved in bullying several times a week. Experience of sibling bullying increases the risk of involvement in bullying in school. Both, bullying between siblings and school bullying make unique contributions to explaining behavioral and emotional problems. There is a clear dose-effect relationship of involvement of bullying at home and at school and behavioral or emotional problems. Those involved in both have up to 14 times increased odds of behavioral or emotional problems compared to those involved in only one context or not at all. The empirical evidence is limited and studies are mostly cross-sectional studies. Nevertheless, the review suggests that for those victimized at home and at school behavioral and emotional problems are highly increased. Sibling relationships appear to be a training ground with implications for individual well-being. Strengthening families and parenting skills and increasing sibling support is likely to reduce bullying and increase well-being.

    Studied here were the links between sibling differences in trajectories of change in the qualities of parent-child relationships and the qualities of sibling relationships across a 2-year period in adolescence. Participants were first- and second-born siblings (M age = 14.94 years for firstborns and M age = 12.46 years for secondborns) from 185 predominantly White, working and middle-class families. In home interviews, siblings reported on their dyadic family relationships. For reports of parent-child warmth but not parent-child conflict, results were consistent with sibling differentiation theory: Increasing differences between siblings over time in parent-child warmth were linked to trajectories of increasing warmth and decreasing conflict in the sibling relationship as reported by firstborns, and increasing warmth in the sibling relationship as reported by secondborns. The findings support the view that sibling differentiation may be a strategy for managing sibling conflict and rivalry.

  16. A family affair: brain abnormalities in siblings of patients with schizophrenia

    Schizophrenia is a severe mental disorder that has a strong genetic basis. Converging evidence suggests that schizophrenia is a progressive neurodevelopmental disorder, with earlier onset cases resulting in more profound brain abnormalities. Siblings of patients with schizophrenia provide an invaluable resource for differentiating between trait and state markers, thus highlighting possible endophenotypes for ongoing research. However, findings from sibling studies have not been systematically put together in a coherent story across the broader age span. We review here the cortical grey matter abnormalities in siblings of patients with schizophrenia from childhood to adulthood, by reviewing sibling studies from both childhood-onset schizophrenia, and the more common adult-onset schizophrenia. When reviewed together, studies suggest that siblings of patients with schizophrenia display significant brain abnormalities that highlight both similarities and differences between the adult and childhood populations, with shared developmental risk patterns, and segregating trajectories. Based on current research it appears that the cortical grey matter abnormalities in siblings are likely to be an age-dependent endophenotype, which normalize by the typical age of onset of schizophrenia unless there has been more genetic or symptom burdening. With increased genetic burdening (e.g. discordant twins of patients) the grey matter abnormalities in (twin) siblings are progressive in adulthood. This synthesis of the literature clarifies the importance of brain plasticity in the pathophysiology of the illness, indicating that probands may lack protective factors critical for healthy development.

    This family study investigated (1) the prevalence of anxiety disorders (ADs) in parents and siblings of children (n = 144) aged 8-18 years with ADs compared to control children (n = 49), and (2) the specificity of relationships between child-mother, child-father, and child-sibling ADs. Clinical interviews were used to assess current DSM-IV-TR ADs in children and siblings, and lifetime and current ADs in parents. Results showed that children with ADs were two to three times more likely to have at least one parent with current and lifetime ADs than the control children (odds ratio (OR) = 2.04 and 3.14). Children with ADs were more likely to have mothers with current ADs (OR = 2.51), fathers with lifetime ADs (OR = 2.84), but not siblings with ADs (OR = 0.75). Specific relationships between mother-child ADs were found for Social Anxiety Disorder (SAD, OR = 3.69) and Generalized Anxiety Disorder (OR = 3.47). Interestingly, all fathers and siblings with SAD came from families of children with SAD. Fathers of children with SAD were more likely to have lifetime ADs themselves (OR = 2.86). Findings indicate that children with ADs more often have parents with ADs, and specifically SAD is more prevalent in families of children with SAD. Influence of parent's (social) ADs should be considered when treating children with ADs.

    Full Text Available We report the case of 3 brothers aged 34, 24, and 22 years, unmarried, who presented to our endocrinology clinic with absence of secondary sexual characters. There was no such history in other siblings, but their maternal uncle had similar complaints. On examination, all 3 had pre-pubertal appearance, voice, and genitalia along with anosmia and bimanual synkinesia. Cryptorchidism was noticed in 2 while third person had small hypoplastic testes. It was also noted that all 3 patients had icthyosis mainly involving trunk, back, and limbs. The hormonal assays were consistent with isolated hypogonadotrophic hypogonadism. IQ testing revealed mental retardation in the 2 patients. Ultrasound showed ectopic right kidney in one patient, atrophic right kidney in the second patient while the third patient had normal kidneys. MRI brain of all the patients showed poorly visualized olfactory tract and bulb. Kallmann syndrome (KS was diagnosed based on hormonal evaluation and MRI results. Of the four types of KS: Synkinesia, renal anomaly, and X-linked pedigree pattern in our patients pointed towards X-linked type 1 KS as the possible cause. But, icthyosis and mental retardation are not usual presentation of type 1 KS. They are usually seen as a result of contiguous gene deletion of KAL1, steroid sulfatase (STS, and mental retardation (MRX gene on X chromosome. Hence, the possible gene defect in our cases is inherited defect in contiguous gene deletion. The contiguous gene deletion as the cause of KS in 3 patients of same family is very rare and worth reporting. Also, the significance of phenotype-genotypic association in Kallmann syndrome is discussed

    In many families, siblings play important roles in shaping each other's outcomes and experiences across development. In adoptive families, siblings may affect adoptees' feelings about adoption and birth family contact. Among "target adoptees" (i.e., 1 participating adopted individual within adoptive families) with siblings who may have also been adopted or the biological children of the adoptive parents, we examined how adoption experiences and individual adjustment from adolescence into emerging adulthood were associated with sibling relationship dynamics. We present 3 studies using longitudinal, mixed method data within the same overarching sample of adoptive families. Study 1 was a follow-up to Berge et al.'s (2006) study of adolescent adoptees and their adopted siblings with birth family contact; we found evidence of changes in the status of contact collectively experienced by 26 adopted sibling pairs when target adoptees were emerging adults. In Study 2, we found that target adoptees (n = 91) with siblings (adopted or not) who were more involved with target adoptees' birth family contact demonstrated more favorable behavioral outcomes than target adoptees who had uninvolved siblings. Finally in Study 3, for target adoptees with siblings who were also adopted (n = 51), results showed that target adoptees felt more positively about their own adoption when siblings expressed similar positive feelings about individual adoption experiences. Implications of our findings are discussed in terms of the enduring contributions of sibling relationships from childhood into adulthood and the unique ways in which adoptive siblings are important in shaping one another's experiences of adoption.

    Understanding the factors that contribute to behavioral traits is a complex task, and partitioning variance into latent genetic and environmental components is a useful beginning, but it should not also be the end. Many constructs are influenced by their contextual milieu, and accounting for background effects (such as gene-environment correlation) is necessary to avoid bias. This study introduces a method for examining the interplay between traits, in a longitudinal design using differential items in sibling pairs. The model is validated via simulation and power analysis, and we conclude with an application to paternal praise and ADHD symptoms in a twin sample. The model can help identify what type of genetic and environmental interplay may contribute to the dynamic relationship between traits using a cross-lagged panel framework. Overall, it presents a way to estimate and explicate the developmental interplay between a set of traits, free from many common sources of bias.

    Although siblings are a fixture of family life, research on sibling relationships lags behind that on other family relationships. To stimulate interest in sibling research and to serve as a guide for future investigations by family scholars, we review four theoretical psychologically oriented perspectives—(a) psychoanalytic-evolutionary, (b) social psychological, (c) social learning, and (d) family-ecological systems—that can inform research on sibling relationships, including perspectives on the nature and influences on developmental, individual, and group differences in sibling relationships. Given that most research on siblings has focused on childhood and adolescence, our review highlights these developmental periods, but we also incorporate the limited research on adult sibling relationships, including in formulating suggestions for future research on this fundamental family relationship.

    2002-02-01

    Full Text Available Abstract Background Family history and twins studies suggest an inherited component to ischemic stroke risk. Candidate gene association studies have been performed but have limited capacity to identify novel risk factor genes. The Siblings With Ischemic Stroke Study (SWISS aims to conduct a genome-wide scan in sibling pairs concordant or discordant for ischemic stroke to identify novel genetic risk factors through linkage analysis. Methods Screening at multiple clinical centers identifies patients (probands with radiographically confirmed ischemic stroke and a family history of at least 1 living full sibling with stroke. After giving informed consent, without violating privacy among other family members, the proband invites siblings concordant and discordant for stroke to participate. Siblings then contact the study coordinating center. The diagnosis of ischemic stroke in potentially concordant siblings is confirmed by systematic centralized review of medical records. The stroke-free status of potentially discordant siblings is confirmed by validated structured telephone interview. Blood samples for DNA analysis are taken from concordant sibling pairs and, if applicable, from 1 discordant sibling. Epstein-Barr virus-transformed lymphoblastoid cell lines are created, and a scan of the human genome is planned. Discussion Conducting adequately powered genomics studies of stroke in humans is challenging because of the heterogeneity of the stroke phenotype and the difficulty of obtaining DNA samples from clinically well-characterized members of a cohort of stroke pedigrees. The multicentered design of this study is intended to efficiently assemble a cohort of ischemic stroke pedigrees without invoking community consent or using cold-calling of pedigree members.

    Project TALENT is a US national longitudinal study of about 377,000 individuals born in 1942-1946, first assessed in 1960. Students in about 1,200 schools participated in a 2-day battery covering aptitudes, abilities, interests, and individual and family characteristics (Flanagan, 1962; www.projectTALENT.org). Follow-up assessments 1, 5, and 11 years later assessed educational and occupational outcomes. The sample includes approximately 92,000 siblings from 40,000 families, including 2,500 twin pairs and 1,200 other siblings of twins. Until recently, almost no behavior genetic research has been conducted with the sample. In the original data collection information was not collected with the intent to link family members. Recently, we developed algorithms using names, addresses, birthdates, and information about family structure to link siblings and identify twins. We are testing several methods to determine zygosity, including use of yearbook photographs. In this paper, we summarize the design and measures in Project TALENT, describe the Twin and Sibling sample, and present our twin-sib-classmate model. In most twin and family designs, the 'shared environment' includes factors specific to the family combined with between-family differences associated with macro-level variables such as socioeconomic status. The school-based sampling design used in Project TALENT provides a unique opportunity to partition the shared environment into variation shared by siblings, specific to twins, and associated with school- and community-level factors. The availability of many measured characteristics on the family, schools, and neighborhoods enhances the ability to study the impact of specific factors on behavioral variation.

  8. Moving beyond the mother-child dyad: exploring the link between maternal sensitivity and siblings' attachment styles.

    Kennedy, Mark; Betts, Lucy R; Underwood, Jean D M

    2014-01-01

    Attachment theory asserts that secure attachment representations are developed through sensitive and consistent caregiving. If sensitive caregiving is a constant characteristic of the parent, then siblings should have concordant attachment classifications. The authors explored maternal attachment quality assessed by the Attachment Q-Set, maternal sensitivity, and specific mother-child interactions between siblings. Hour-long observations took place in the homes of 9 preschool sibling pairs and their immediate caregivers. The interactions were analyzed using a modified version of Bales' Small Group Analysis. The results reveal attachment discordance in a third of sibling pairs. While maternal sensitivity was higher with older siblings and mothers displayed more positive emotions when interacting with their younger siblings, attachment quality was not associated with birth order. Therefore, a shift toward a more contextual, family-based perspective of attachment is recommended to further understand how attachment strategies are created and maintained within the child's everyday context.

    Among typically developing children, having sibling relationships promotes the development of social skills. This is a retrospective study of the effect of having sibling/s on the severity of the clinical presentation of autism spectrum disorder (ASD). The study included 112 children, 99 males and 15 females, mean age 29.6 ± 9.2 months, diagnosed with ASD. The study population was composed of a group of children with ASD who had older typically developing sibling/s (n = 56) pair-matched for age and cognitive level to a group of children with ASD without sibling/s. Each participant underwent a comprehensive assessment using standardized tests. The group with older sibling/s had less severe observed social deficits (Autism Diagnostic Observation Schedule-Social Affect calibrated severity scales [ADOS-SA-CSS]) and fewer reported non-verbal communication impairments (Autism Diagnostic Interview-Revised [ADI-R]). Regression analyses revealed that, for the ADOS-SA-CSS, higher cognitive level and having older sibling/s were associated with less severe observed social affect deficits. This model explained 32.0 % of the variance. For the ADI-R communication scores, older age, higher cognitive level and having older sibling/s were associated with less severe reported non-verbal communication impairments. This model explained 33.0 % of the variance. The main finding in this study is that a familial factor, specifically having older sibling/s, was associated with better social communication abilities in children with ASD, in addition to age and cognitive ability. Having sibling/s may offer opportunities for the child with ASD to experience social interactions with children and to acquire communication skills.

    Sibling relationships are among the most unique social connections, significantly affecting psychosocial adjustment. Previous reviews in the fields of chronic illness and disability have concluded that unaffected siblings of children with long-term conditions are at risk of poorer psychological functioning as a consequence. Much research has investigated the psychosocial impact of CL/P on affected individuals and their parents, yet comparatively little is known about the impact on other close family members.   To gain a better understanding of the experience of unaffected siblings of children born with CL/P, with a view to informing service provision and support.   Individual qualitative interviews conducted over the telephone/Internet with five siblings and eight parents, including five sibling-parent pairs from the same family.   Thematic analysis identified three key themes applicable across both parent and sibling interviews: perceptions of positive and negative impacts, factors affecting the degree of impact, and support for families.   This study provides insight into a population that is often overlooked in the context of cleft care. The analysis identified a number of sibling support and information needs, along with suggestions of how to incorporate support for siblings in practice. The findings suggest that an inclusive approach to health care encompassing all members of the family is essential for optimal familial adjustment.

    We examined how parental characteristics and other aspects of family background were associated with the development of eating disorders (ED) in males and females. We used register data and record linkage to create the prospective, total-population study the Stockholm Youth Cohort. This cohort comprises all children and adolescents who were ever residents in Stockholm County between 2001 and 2007, plus their parents and siblings. Individuals born between 1984 and 1995 (N = 249, 884) were followed up for ED from age 12 to end of 2007. We used Cox regression modeling to investigate how ED incidence was associated with family socioeconomic position, parental age, and family composition. In total, 3,251 cases of ED (2,971 females; 280 males) were recorded. Higher parental education independently predicted a higher rate of ED in females [e.g., adjusted hazard ratio (HR) 1.69 (95% CI: 1.42, 2.02) for degree-level vs. elementary-level maternal education], but not in males [HR 0.73 (95% CI: 0.42, 1.28), p siblings was associated with lower rate of ED [e.g., fully adjusted HR 0.92 (95% CI: 0.88, 0.97) per sibling], whereas an increasing number of half-siblings was associated with a higher rate [HR 1.05 (95% CI: 1.01, 1.09) per sibling]. The effect of parental education on ED rate varies between males and females, whereas the effect of number of siblings varies according to whether they are full or half-siblings. A deeper understanding of these associations and their underlying mechanisms may provide etiological insights and inform the design of preventive interventions.

    Adrian J Lowe

    Full Text Available BACKGROUND: It has been proposed that maternal obesity during pregnancy may increase the risk that the child develops allergic disease and asthma, although the mechanisms underpinning this relationship are currently unclear. We sought to assess if this association may be due to confounding by genetic or environmental risk factors that are common to maternal obesity and childhood asthma, using a sibling pair analysis. METHODS: The study population comprised a Swedish national cohort of term children born between 1992 and 2008 to native Swedish parents. Maternal body mass index (BMI was measured at 8-10 weeks gestation. Unconditional logistic regression models were used to determine if maternal obesity was associated with increased risk of inhaled corticosteroid (ICS in 431,718 first-born children, while adjusting for potential confounders. An age-matched discordant sib-pair analysis was performed, taking into account shared genetic and environmental risk factors. RESULTS: Maternal over-weight and obesity were associated with increased risk that the child would require ICS (for BMI≥35 kg/m(2, aOR = 1.30, 95%CI = 1.10-1.52 compared with normal weight mothers in children aged 6-12 years. Similar effects were seen in younger children, but in children aged 13-16 years, maternal obesity (BMI≥30 was related to increased risk of ICS use in girls (aOR = 1.28, 95%CI = 1.07-1.53 but not boys (OR = 1.05, 95%CI = 0.87-1.26. The sib-pair analysis, which included 2,034 sib-pairs older than six years who were discordant for both ICS use and maternal BMI category, failed to find any evidence that increasing maternal weight was related to increased risk of ICS use. CONCLUSION: Maternal obesity is associated with increased risk of childhood ICS use up to approximately 12 years of age, but only in girls after this age. These effects could not be confirmed in a sib pair analysis, suggesting either limited statistical power, or the effects

    Full Text Available INTRODUCTION: Patients and family members undergo different experiences of suffering from emotional disorders during ICU stay and after ICU discharge. The purpose of this study was to compare the incidence of anxiety, depression and post-traumatic stress disorder (PTSD symptoms in pairs (patient and respective family member, during stay at an open visit ICU and at 30 and 90-days post-ICU discharge. We hypothesized that there was a positive correlation with the severity of symptoms among pairs and different patterns of suffering over time. METHODS: A prospective study was conducted in a 22-bed adult general ICU including patients with >48 hours stay. The Hospital Anxiety and Depression Scale (HADS was completed by the pairs (patients/respective family member. Interviews were made by phone at 30 and 90-days post-ICU discharge using the Impact of Event Scale (IES and the HADS. Multivariate models were constructed to predict IES score at 30 days for patients and family members. RESULTS: Four hundred and seventy one family members and 289 patients were interviewed in the ICU forming 184 pairs for analysis. Regarding HADS score, patients presented less symptoms than family members of patients who survived and who deceased at 30 and 90-days (p<0.001. However, family members of patients who deceased scored higher anxiety and depression symptoms (p = 0.048 at 90-days when compared with family members of patients who survived. Patients and family members at 30-days had a similar IES score, but it was higher in family members at 90-days (p = 0.019. For both family members and patients, age and symptoms of anxiety and depression during ICU were the major determinants for PTSD at 30-days. CONCLUSIONS: Anxiety, depression and PTSD symptoms were higher in family members than in the patients. Furthermore, these symptoms in family members persisted at 3 months, while they decreased in patients.

    Identifying early markers of future obesity risk can help target preventive interventions. Several studies have shown that a heartier appetite in infancy is a risk factor for more rapid weight gain, but to date no investigations have been able to rule out familial confounding. To use a sibling design (data from same-sex, dizygotic twin pairs) to test the hypothesis that sibling differences in infant appetite predicted differential weight gain during childhood. Gemini is a population-based twin cohort among the general United Kingdom population born between March 1, 2007, and December 15, 2007. Growth trajectories were analyzed from birth to age 15 months. Appetite-discordant pairs were selected from 800 nonidentical, same-sex twin pairs. Appetite during the first 3 months of life was assessed with the food responsiveness (FR) and satiety responsiveness (SR) subscales from the Baby Eating Behaviour Questionnaire. Discordance was defined as a within-pair difference of at least 1 SD. A mean of 11.5 weight measurements per child were available between birth and age 15 months. Multilevel models, adjusted for sex and birth weight, compared growth curves for the higher-appetite vs lower-appetite twins. In total, 172 pairs were discordant for SR and 121 pairs for FR. Within-pair analyses showed that those with higher FR and those with lower SR grew faster than their sibling. At age 6 months, those with higher FR were 654 (95% CI, 395-913) g heavier and at age 15 months were 991 (95% CI, 484-1498) g heavier. For sibling pairs discordant for SR, the weight differences between siblings were 637 (95% CI, 438-836) g at age 6 months and 918 (95% CI, 569-1267) g at age 15 months. A heartier appetite (indexed with higher FR or lower SR) in early infancy is prospectively associated with more rapid growth up to age 15 months in a design controlling for potential familial confounding, supporting a causal role for appetite in childhood weight gain. Appetite could be an early marker

    This feasibility study examines whether the theory of planned behavior can predict supportive behavior provided by either parents to their offspring--or adult siblings to their brothers and sisters--with an intellectual disability living in 2 Israeli institutional care facilities. Participants were 67 parents and 63 siblings who were interviewed at baseline regarding their intentions to visit their offspring or sibling in the institutional care facility, to contact the caregiving staff, and to accept visits at home. Parents' and siblings' behavior regarding visitation and supportive behavior was examined after 6 months by caregiving staff. Core findings indicated that subjective norms in siblings and parents predicted frequency of home visits. Perceived behavioral control predicted frequency of contact between siblings and staff. Differences between parents and siblings regarding their supportive behaviors are discussed with respect to social work practice.

  18. Sibling influences on childhood development.

    Science.gov (United States)

    Dunn, J

    1988-03-01

    To summarize the main points concerning sibling influence: 1. That siblings play a causal role in the development of aggressive behavior, in children's style of conflict behavior and in cooperative fantasy play is strongly suggested by recent research. 2. Marked problems in the sibling relationship are indicative of other problems, but a causal role for siblings is not established, other than for aggressive behavior. 3. Family factors are closely involved in the quality of sibling relationships--and thus in sibling influence, namely differential parental behavior, and the emotional climate of the family. That is, it is important not to consider the sibling relationship in isolation from other family relationships. 4. Studies of families under stress indicate heightened importance of these family factors. 5. It is likely, but not yet established, that later-born siblings are influenced by first-born in socio-cognitive development and gender identity. 6. Finally it should be noted that an important theme in current research on siblings is a concern with the question of why siblings develop to be so different from one another. It has been shown that the major source of environmental influence on the development of individual differences is within-family rather than between-family differences in experience (Plomin & Daniels, 1987). The different experiences each sibling may have within their relationship is one potential source of such differential environmental influence. Thus documenting the influence of siblings upon each other takes on added significance: By clarifying the extent and nature of this influence we will gain not only useful clinical information but illumination on a developmental principle of very general significance.

    1999-01-01

    This study examined the influence that residential dislocations have on child behavior problems, depression, peer competence, cognitive competence, and the quality of sibling relations in a sample of 70 Head Start children, aged 32 to 67 months, and their older brothers and sisters, aged 48 to 155 months. This was the first study to investigate the sibling relationship in the context of high residential mobility. Information on child characteristics was obtained from mothers and teachers. Sibling data (warmth/harmony and conflict) were obtained from coding videotaped interactions. Child emotionality was found to be an important moderator of the effects of residential mobility on young, poor children and their siblings; caregiver conflict was a less powerful moderator of these effects. Residential instability seemed to compromise the warmth/harmony of the sibling relationship. It was concluded that the effects of residential instability are complex and cannot be understood without considering child characteristics, such as temperament, and the family context in which the child lives.

    Hughes, Claire; McHarg, Gabrielle; White, Naomi

    2018-04-01

    Sibling relationships are characterized by familiarity and emotional intensity. Alongside frequent shared play, sibling interactions feature complementary interactions (e.g. teaching, caregiving) reflecting age-related asymmetries in socio-cognitive skills. These aspects may underpin sibling influences on prosocial behavior: theoretical accounts of social influences on prosocial behavior highlight emotion sharing, goal alignment, the intrinsically rewarding nature of social interaction, and scaffolding of social norms. Taking a fine-grained approach to prosocial behavior, we examine these processes in relation to sibling influences on children's comforting, sharing, and helping. Emergent themes include: developmental change in the nature of sibling influences on prosocial behavior, the need to consider sibling influences in the wider family context, and the importance of individual differences in the quality of sibling relationships.

    Background: Several factors are involved in determining a child's need for special education (Sweden). Thus, the value of brain magnetic resonance imaging (MRI) for subjects with learning and intellectual disabilities is uncertain. Purpose: To evaluate the usefulness of MRI in the diagnostic process of siblings with learning and intellectual disabilities and need for full-time SE. Material and Methods: Altogether, 119 siblings (mean age 11.9 years) from families in which two or more children attended/had previously attended full-time SE underwent prospective brain MRI. SE grouping included three levels, from specific learning disabilities (level 1) to global intellectual disabilities (level 3). Forty-three controls (level 0, mean age 12.0 years) attended mainstream education groups. Signal intensity and structural abnormalities were analyzed, and areas of the cerebrum, posterior fossa, corpus callosum, vermis and brain stem, and diameters of the corpus callosum were measured. In analyses, all area measurements were calculated in proportion to the total inner skull area. Results: Abnormal finding in MRI was more common for siblings (n=62; 52%) in SE (58% for level 3; 49% for level 2; 35% for level 1) than for controls (n=13; 16%). The siblings showed enlarged supra- (P<0.001) and infratentorial (P=0.015) cerebrospinal fluid (CSF) spaces and mild corpus callosum abnormalities (P=0.003) compared to controls. Siblings in SE had smaller inner skull area than controls (P<0.001). Further, the relative area of the mesencephalon (P=0.027) and the diameter of the body of the corpus callosum (P=0.015) were significantly smaller than in controls. In binary logistic regression analysis, enlarged supratentorial CSF spaces increased the probability of SE (odds ratio 4.2; P=0.023). Conclusion: Subjects with learning and intellectual disabilities commonly have more MRI findings than controls. Enlarged supratentorial CSF spaces were a frequent finding in siblings in full

  12. Are there individual and sibling differences in appraisals of interparental conflict?

    Lucas-Thompson, Rachel G; George, Melissa W

    2017-10-01

    Despite decades of empirical literature documenting the harmful effects of frequent, intense, violent, and unresolved interparental conflict on children's adjustment, there is considerable variability in the extent to which marital conflict contributes to the development of children's emotional and behavioral problems. Past research has documented links between properties of interparental conflict itself (e.g., intensity, frequency), children's appraisals of conflict, and children's outcomes, yet less is known about the role of individual and family characteristics in predicting children's conflict appraisals. Sibling studies may be especially helpful in understanding these individual differences yet are notably lacking in marital conflict research. The current study examines individual- and family-characteristic predictors of adolescents' appraisals of conflict in a study of 153 adolescents as well as sibling similarities in conflict appraisals in a subsample of 50 pairs of siblings. Controlling for parent reports of the frequency, intensity, and resolution of interparental conflict, parent-child relationship quality and stressful life events predicted conflict appraisals. In addition, there was nonindependence of sibling appraisals of conflict properties, but self-blame and threat appraisals appeared independent across siblings. Greater discrepancies in siblings' conflict appraisals were related to more negative marital conflict and discrepancies in parent-child relationship quality, and were found in mixed-sex sibling dyads. Implications for future studies on factors that impact children's appraisals of conflict and in particular making use of sibling studies to examine shared environmental and individual influences on appraisals is highlighted.

    Wallace, Lacey N

    Sibling substance use is a known correlate of adolescent substance use. Yet, not all siblings are equally influential. Sibling influence has been found to vary by age gap, sex, and birth order. Little research, however, has investigated whether siblings' peer context is also a source of variation. The present study tested whether more popular siblings were more influential for adolescent use of cigarettes, alcohol, and marijuana. Data were obtained from sibling pairs in the National Longitudinal Study of Adolescent Health. Findings indicate that older siblings have more influence on younger sibling marijuana use when they have more friends. These findings contribute to prior work examining which siblings are more influential and highlight the need to consider siblings as part of a greater peer context.

    Highlights: ► We deduce a family of integrable differential–difference equations. ► We present a discrete Hamiltonian operator involving two arbitrary real parameters. ► We establish the bi-Hamiltonian structure for obtained integrable family. ► Liouvolle integrability of the obtained family is demonstrated. ► Every equation in obtained family is factored through the binary nonlinearization. - Abstract: A family of integrable differential–difference equations is derived by the method of Lax pairs. A discrete Hamiltonian operator involving two arbitrary real parameters is introduced. When the parameters are suitably selected, a pair of discrete Hamiltonian operators is presented. Bi-Hamiltonian structure of obtained family is established by discrete trace identity. Then, Liouville integrability for the obtained family is proved. Ultimately, through the binary nonlinearization of the Lax pairs and adjoint Lax pairs, every differential–difference equation in obtained family is factored by an integrable symplectic map and a finite-dimensional integrable system in Liouville sense.

    Troyer syndrome (MIM#275900) is an autosomal recessive form of complicated hereditary spastic paraplegia. It is characterized by progressive lower extremity spasticity and weakness, dysarthria, distal amyotrophy, developmental delay, short stature, and subtle skeletal abnormalities. It is caused by deleterious mutations in the SPG20 gene, encoding spartin, on Chromosome 13q13. Until now, six unrelated families with a genetically confirmed diagnosis have been reported. Here we report the clinical findings in three brothers of a consanguineous Moroccan family, aged 24, 17, and 7 yr old, with spastic paraplegia, short stature, motor and cognitive delay, and severe intellectual disability. Targeted exon capture and sequencing showed a homozygous nonsense mutation in the SPG20 gene, c.1369C>T (p.Arg457*), in the three affected boys. © 2017 Dardour et al.; Published by Cold Spring Harbor Laboratory Press.

    2014-04-01

    The p53 family (p53, p63 and p73) is intimately linked with an overwhelming number of cellular processes during normal physiological as well as pathological conditions including cancer. The fact that these proteins are expressed in myriad isoforms, each with unique biochemical properties and distinct effects on tumorigenesis, complicates their study. A case in point is Squamous Cell Carcinoma (SCC) where p53 is often mutated and the ΔNp63 isoform is overexpressed. Given that p53 and p63 can hetero-dimerize, bind to quite similar DNA elements and share common co-factors, any alterations in their individual expression levels, activity and/or mutation can severely disrupt the family equilibrium. The burgeoning genomics data sets and new additions to the experimental toolbox are offering crucial insights into the complex role of the p53 family in SCC, but more mechanistic studies are needed. © 2014 John Wiley & Sons A/S.

    We obtained evidence from a large study in Dutch twins (N = 8387) and siblings (N = 2295) that variation in loneliness has a genetic component. The heritability estimate for loneliness, which was assessed as an ordinal trait, was 40% and did not differ between males and females. There were 682

    High level of caries activity is related to organisms in the dental plaque with high acidogenesis capacity. To test salivary pH in children of the same family and compare it with their caries status. To compare pH levels between children and their parents. To examine the relationship between pH and caries status among children of the same family and their parents. We examined 123 children and adolescents aged 3-18, (73 boys and 50 girls) and 33 adults, (12 men and 21 women), parents of these children. Caries status was examined clinically, using DMF index. Salivary pH measurements were made by a digital pH meter. Among adults, increase in patient age led to increased DMF (p = 0.005). The higher the pH, the lower the DMF (p = 0.037). Among men, DMF was lower by 3 compared to women (p = 0.049). Children's pH correlated with the parents' (p = 0.004). Children's DMF correlated to their pH (p = 0.001). Children's pH was the best predictor of their DMF (R2 = 0.309, p = 0.001). Among children, the higher the pH, the lower the DMFT. Children's pH was the best predictor of their DMF.

    Usher syndrome is a heterogeneous group of disorders of autosomal recessive inheritance characterized by retinitis pigmentosa and congenital sensorineural hearing loss. Two types are accepted clinically: type I is associated with profound congenital deafness with progressive pigmentary retinopathy and total loss of vestibular function. Type II is a milder form, with moderate-to-profound hearing loss and a milder form of retinitis pigmentosa. Vestibular function is preserved. A total of five loci have been identified as accounting for the two distinct phenotypic presentations. We describe a consanguineous family of Pakistani origin whose four children all are affected with Usher syndrome type I. DNA analysis showed non-linkage to any of the loci already identified as tightly linked to the Usher syndrome type I.

    2015-06-01

    To illuminate processes that contribute to the development of sibling differences, this study examined cross-lagged links between parents' beliefs about sibling differences in academic ability and differences between siblings' grade point averages (GPAs), and cross-lagged links between differences in siblings' GPAs and sibling differences in academic interests. Data were collected from mothers, fathers, firstborn youth (M age at Time 1 = 15.71, SD = 1.07), and secondborn youth (M age at Time 1 = 13.18, SD = 1.29) from 388 European American families on 3 annual occasions. Findings revealed that, after controlling for siblings' average grades and prior differences in performance, parents' beliefs about sibling differences in academic ability predicted differences in performance such that youth rated by parents as relatively more competent than their sibling earned relatively higher grades the following year. Siblings' relative school performance, however, did not predict parents' beliefs about differences between siblings' competencies. Further, after controlling for average interests and grades, sibling differences in GPA predicted differences in siblings' interests such that youth who had better grades than their siblings reported relatively stronger academic interests the following year. Differences in interest, however, did not predict sibling differences in GPA. Findings are discussed in terms the role of sibling dynamics in family socialization.

    2014-10-01

    As professionals working in a specialised unit for prepubescent anorexic children, we are very often concerned with the siblings of our young patients who are daily faced with anorexia nervosa. Although it is an undeniable subject of prevention, research on the topic remains scarce. Based on our clinical experience, this article thus proposes to give a few landmarks to health professionals likely to support these siblings in order to prevent anxious and depressive disorders as well as eating disorders. If guided, supported and informed on anorexia nervosa, siblings can adopt adequate coping strategies when confronted to their sibling's anorexic cognitions and behaviours. We also encourage parents to pay close attention to the needs of their other children, especially to remain receptive to the youngest ones or, if unavailable to find adult carers (grandparents, family, friends). We also guide these children, who are eager to help their anorexic sibling, to remain in a brotherly role. Siblings must be informed about anorexia nervosa. Such information enables them to have a better understanding of their sister's thoughts and attitudes. It also leads to a better understanding of the reasons why anorexia has such a significant impact on family routine, among other things by reducing parental availability. Beyond enabling siblings to adopt adequate coping strategies, such provision of support also contributes to the prevention of mental illness and the maintenance of adequate sibling and family relationships.

    Unbalanced translocations involving X and Y chromosomes are rare and associated with a contiguous gene syndrome. The clinical phenotype is heterogeneous including mainly short stature, chondrodysplasia punctata, ichthyosis, hypogonadism, and intellectual disability. Here, we report 2 brothers with peculiar gestalt, short stature, and hearing loss, who harbor an X/Y translocation. Physical examination, brainstem acoustic potential evaluation, bone age, hormonal assessment, and X-ray investigations were performed. Because of their dysmorphic features, karyotyping, FISH, and aCGH were carried out. The probands had short stature, hypertelorism, midface hypoplasia, sensorineural hearing loss, normal intelligence as well as slight radial and ulnar bowing with brachytelephalangy. R-banding identified a derivative X chromosome with an abnormally expanded short arm. The mother was detected as a carrier of the same aberrant X chromosome. aCGH disclosed a 3.1-Mb distal deletion of chromosome region Xp22.33pter. This interval encompasses several genes, especially the short stature homeobox (SHOX) and arylsulfatase (ARSE) genes. The final karyotype of the probands was: 46,Y,der(X),t(X;Y)(p22;q12).ish der(X)(DXYS129-,DXYS153-)mat.arr[hg19] Xp22.33(61091_2689408)×1mat,Xp22.33(2701273_3258404)×0mat,Yq11.222q12 (21412851_59310245)×2. Herein, we describe a Moroccan family with a maternally inherited X/Y translocation and discuss the genotype-phenotype correlations according to the deleted genes. © 2017 S. Karger AG, Basel.

    2008-01-01

    Full Text Available The purpose of the present study was: (a To describe the relationship in sibling's dyads, separated in two groups – G1, with pre-adolescent mentally retarded sibling, and G2, with this adult sibling; (b To compare the performance of both groups in the interactions; and (3 To evaluate differences in the relationships between the groups when family social support is taken into account. Sessions of sibling's interactions were videotaped, and self-report instruments were used. The caretakers answered scales of social support. Results suggested differences concerning the behavior of the helper of the sibling with characteristic development, with highest occurrence in G1. Scales' results indicated statistically significant difference for the Parenting Support from Family/Friends Scale, showing less support for G1. It is possible to suggest that because families from G1 have less support from this level from families and friends, a bigger demand of help is required from the disabled member, which can be compensated by the young siblings with typical development, who perform the helper's role in greater level than the adults.

    2013-02-01

    Siblings play a significant but neglected role in family socialization dynamics, and focusing on the sibling relationship is a non-stigmatizing point of entry into the family for prevention programming. Siblings are Special (SAS) was designed as a universal program that targets both sibling relationship and parenting mediating processes in middle childhood to prevent behavior problems in adolescence. We describe the theoretical framework underlying SAS, the SAS curriculum, and the feasibility of the program based on a study of 128 middle-childhood aged sibling dyads. Data on the quality of program implementation, program fidelity, siblings' engagement, and ratings of impact indicated the SAS program was acceptable to families and schools, that the curriculum could be implemented with high fidelity, that siblings and parents participated at high levels and were highly engaged, and that, from the perspective of group leaders, school administrators and parents, the program had a positive impact on the siblings.

    Two siblings who developed fifth-decade-onset, concurrent progressive sensory ataxia, dysarthria, and ophthalmoparesis were found to be homozygous for the p.A467T mutation of the polymerase gamma (POLG) gene. The clinical course in both subjects was progression to severe disability. The enlarging spectrum of sensory ataxic neuropathies associated with mitochondrial DNA (mtDNA) instability and POLG mutations should be recognized and considered in the differential diagnosis of this unusual presentation.

  17. Considerations of Elder Sibling Closeness in Predicting Younger Sibling Substance Use: Social Learning versus Social Bonding Explanations

    Samek, Diana R.; Rueter, Martha A.

    2011-01-01

    Adolescent siblings are often similar in a variety of adjustment outcomes, yet little is known about the processes that explain sibling influences during adolescence. Two alternative explanations were tested, attachment (based in social bonding theory) and anaclitic identification (based in social learning theory). Hypotheses were tested using a sample of 613 adolescent sibling pairs (206 non-adopted, 407 adopted; elder sibling Mage = 16.1, younger sibling Mage = 13.8) across three sibling contexts (gender composition, age difference, and genetic similarity). Attachment explanations were supported such that the greater the perceived sibling emotional and behavioral closeness, the lower the likelihood of substance use; however, there were considerable moderating effects of sibling gender composition. Anaclitic identification explanations were not supported; closeness and elder sibling substance use did not interact to predict younger sibling substance use. Overall, this research adds to a body of work demonstrating important sibling influences on adolescent substance use. PMID:21988080

  18. Enhancing the prediction of protein pairings between interacting families using orthology information

    2008-01-01

    Full Text Available Abstract Background It has repeatedly been shown that interacting protein families tend to have similar phylogenetic trees. These similarities can be used to predicting the mapping between two families of interacting proteins (i.e. which proteins from one family interact with which members of the other. The correct mapping will be that which maximizes the similarity between the trees. The two families may eventually comprise orthologs and paralogs, if members of the two families are present in more than one organism. This fact can be exploited to restrict the possible mappings, simply by impeding links between proteins of different organisms. We present here an algorithm to predict the mapping between families of interacting proteins which is able to incorporate information regarding orthologues, or any other assignment of proteins to "classes" that may restrict possible mappings. Results For the first time in methods for predicting mappings, we have tested this new approach on a large number of interacting protein domains in order to statistically assess its performance. The method accurately predicts around 80% in the most favourable cases. We also analysed in detail the results of the method for a well defined case of interacting families, the sensor and kinase components of the Ntr-type two-component system, for which up to 98% of the pairings predicted by the method were correct. Conclusion Based on the well established relationship between tree similarity and interactions we developed a method for predicting the mapping between two interacting families using genomic information alone. The program is available through a web interface.

    This study explored psychological adjustment and sibling relationships of siblings of children with life-limiting conditions (LLCs), expanding on previous research by defining LLCs using a systematic classification of these conditions. Thirty-nine siblings participated, aged 3-16 years. Parents completed measures of siblings' emotional and behavioural difficulties, quality of life, sibling relationships and impact on families and siblings. Sibling and family adjustment and relationships were compared with population norms, where available, and to a matched comparison group of siblings of children with autistic spectrum disorder (ASD), as a comparable 'high risk' group. LLC siblings presented significantly higher levels of emotional and behavioural difficulties, and lower quality of life than population norms. Their difficulties were at levels comparable to siblings of children with ASD. A wider impact on the family was confirmed. Family socio-economic position, time since diagnosis, employment and accessing hospice care were factors associated with better psychological adjustment. Using a systematic classification of LLCs, the study supported earlier findings of increased levels of psychological difficulties in siblings of children with a LLC. The evidence is (i) highlighting the need to provide support to these siblings and their families, and (ii) that intervention approaches could be drawn from the ASD field. © 2016 John Wiley & Sons Ltd.

    The peroxisome proliferator activated receptor (PPAR) gamma2 is a transcription factor that has been shown to be involved in adipocyte differentiation, adipogenesis, and insulin sensitivity. To address the role of PPARgamma2 in glucose homeostasis and insulin sensitivity, among many other objectives, we conducted a sibling-controlled association study in a multicenter program - the Stanford Asian-Pacific Program in Hypertension and Insulin Resistance (SAPPHIRe). Approximately 2525 subjects in 734 Chinese and Japanese families have been recruited from six field centers for SAPPHIRe. In total, 1702 subjects including parents and siblings from 449 families have been genotyped for PPARgamma2, of which 328 families were Chinese and 121 Japanese. Only 88 subjects of the 1525 siblings screened for the P12A polymorphism were found to be carriers of the A variant, the most common variant of the PPARgamma2 gene. A variant frequencies of the siblings were 4.27% in Chinese and 2.72% in Japanese. A sibling-controlled association study was performed through genetically discordant sibships (i.e., P/P genotype vs. P/A + A/A genotypes). Specifically, we examined whether there were differences in metabolic variables between the discordant siblings within families. In total, 88 subjects carrying either 1 or 2 A alleles had at least one sibling who was discordant for the P12A polymorphism, yielding a total of 180 individuals from 47 families for analyses, among which 92 siblings were homozygous for wild-type P allele. Siblings with the A variant tended to have lower levels of fasting plasma glucose (OG-10), and lower glucose levels at 60 min following oral glucose loading after adjusting for age, gender, and body mass index. Using a mixed model treating family as a random effect, we found that P12A polymorphism of the PPARgamma2 gene contributes significantly to the variance in fasting plasma glucose, glucose level at 60 min, and insulin-resistance homeostasis model assessment.

    Within the process of political socialization, the family is of particular importance. Apart from parents, however, little is known about the role of other close family members. The present study examined if siblings affect each other's intergroup attitudes (i.e., intolerance towards immigrants, social dominance orientation). Drawing on a sample of 362 sibling dyads (older siblings: M age  = 17.77, 53.6% female; younger siblings: M age  = 13.61, 61.3% female), the results showed that older siblings' intergroup attitudes predicted younger siblings' attitudes, but this effect was moderated by gender. Specifically, older siblings' intolerance and social dominance orientation were only found to affect their younger sisters, yet not their younger brothers. Although younger siblings' intergroup attitudes had no main effect on older siblings, a significant moderation by age indicated that younger siblings affected older siblings' social dominance orientation with increasing age. These moderation effects of age and gender were not mediated by the quality of family relationships. The findings also remained the same when parental intergroup attitudes were taken into account. While siblings were generally identified as an important agent of political socialization in youth, the results also highlight the necessity to further examine the mechanism that either facilitate or hinder sibling effects.

    2017-01-01

    Few large studies have examined the heritability of venous thromboembolism (VTE). Moreover, twin studies have been suggested to overestimate heritability. The aim of the present study was to determine the heritability nationwide in the general Swedish population using full siblings and half-siblings. VTE was defined using the Swedish patient register. Full sibling (FS) and half-sibling (HS) pairs born 1950-1990 were obtained from the Swedish Multi-generation Register. A maximum of 5years age difference was allowed. We also required that the individuals within the pair should reside in the same household for at least 8years or not at all (0years) before the youngest turned 16. Information about sibling pair residence within the same household, small residential area, and municipality was obtained from Statistics Sweden. We assumed three potential sources of liability to VTE: additive genetic (A), shared (or common/familial) environment (C), and unique environment (E) components. Totally 881,206 FS pairs and 95,198 HS pairs were included. The full model predicted heritability for VTE with 47% for males and 40% for females. Environmental factors shared by siblings contributed to 0% of the variance in liability for both sexes, and unique environment (E) components accounted for 53% in males and 60% in females. The high heritability of VTE risk indicates that genetic susceptibility plays a substantial role for VTE in the Swedish general population. Overestimation of heritability from twin studies is not likely. The proportion of the variance attributable to shared familial environment factors is small.

    2003-04-01

    Data from 296 sibling pairs (mean ages 10 and 13 years), their primary caregivers, and census records were used to test the hypothesis that African American children's likelihood of developing conduct problems associated with harsh parenting, a lack of nurturant-involved parenting, and exposure to an older sibling's deviance-prone attitudes and behavior would be amplified among families residing in disadvantaged neighborhoods. A latent construct representing harsh-inconsistent parenting and low levels of nurturant-involved parenting was positively associated with younger siblings' conduct disorder symptoms, as were older siblings' problematic attitudes and behavior. These associations were strongest among families residing in the most disadvantaged neighborhoods. Future research and prevention programs should focus on the specific neighborhood processes associated with increased vulnerability for behavior problems.

    Kippen, Rebecca; Walters, Sarah

    2012-01-01

    Evidence drawn from nineteenth-century Belgian population registers shows that the presence of similarly aged siblings competing for resources within a household increases the probability of death for children younger than five, even when controlling for the preceding birth interval and multiple births. Furthermore, in this period of Belgian history, such mortality tended to cluster in certain families. The findings suggest the importance of segmenting the mortality of siblings younger than five by age group, of considering the presence of siblings as a time-varying covariate, and of factoring mortality clustering into analyses.

    Genetics and mental health professionals increasingly provide education and counseling related to risk for psychiatric illness, but there is insufficient evidence about patient perceptions and needs to guide such interventions. Affected individuals and relatives may perceive increased family risk and have interest in genetic education and counseling. Our objectives were to explore perceptions of family vulnerability, perceived control, and coping strategies related to familial risk and needs from genetic counseling. Our methods included conducting semi-structured interviews (n = 48) with individuals with bipolar disorder (BPD) and unaffected siblings. Content analysis generated descriptive data that provide guidance for clinical interventions and themes to evaluate in future studies. The results showed that participants perceived increased personal and family risk, attributing BPD to genes and family environment. Causal attributions were often uncertain and at times inconsistent. Participants wished to modify psychiatric risk to relatives, but were uncertain how to do so; despite the uncertainty, most parents reported risk-modification efforts. Efforts to cope with family vulnerability included monitoring and cognitive distancing. Participants endorsed the usefulness of education and psychological support, but described more ambivalence about receiving risk assessment. Educational and supportive interventions around family risk for BPD should focus on perceptions of cause and vulnerability, reproductive decision-making, and early intervention and risk modification in young relatives. Psychological support is an important component. Providers should evaluate patient coping strategies, which could facilitate or hinder genetic counseling interventions, and should not assume interest in quantitative risk assessment. 2009 Wiley-Liss, Inc.

    The present study examined the concordance of the Family History Interview for Personality Disorders (FHIPD) with diagnoses based on direct interviews and between pairs of informants. Subjects were 224 probands participating in a series of studies of the familial transmission of mood and personality disorders and their first-degree relatives. Proband informants and relatives provided information about themselves on the Structured Clinical Interview for DSM-III-R (SCID), Personality Disorder Examination (PDE), and Eysenck Personality Questionnaire (EPQ). Information from informants about relatives was collected with the FHIPD. All assessments were made blindly and independently. Using Kappa, concordance between proband informants' family histories and relative direct reports on specific personality disorders was low, ranging from -.01 to .28, with a median of .10. Kappa for a diagnosis of any personality disorder was .16. When two independent informant reports were compared, Kappas for specific Axis II disorders ranged from .10 to .72, with a median of .28. Kappa for a diagnosis of any personality disorder was .36. These data suggest that subjects and informants provide different perspectives on Axis II psychopathology, and support the use of both sources of information whenever possible.

Problems may be related to socioeconomic status; family size; age, sex, and birth order of the sibling; and severity of the handicap. (GDC)

    Parents' differential treatment is a common family dynamic that has been linked to youth's well-being in childhood and adolescence in European American families. Much less is known, however, about this family process in other ethnic groups. The authors examined the longitudinal associations between parents' differential treatment (PDT) and both depressive symptoms and risky behaviors of Mexican-origin sibling pairs from early adolescence through young adulthood. They also tested the moderating roles of cultural orientations as well as youth age, gender and sibling dyad gender constellation in these associations. Participants were mothers, fathers, and 2 siblings from 246 Mexican-origin families who participated in individual home interviews on 3 occasions over 8 years. Multilevel models revealed that, controlling for dyadic parent-child relationship qualities (i.e., absolute levels of warmth and conflict), adolescents who had less favorable treatment by mothers relative to their sibling reported more depressive symptoms and risky behavior, on average. Findings for fathers' PDT emerged at the within-person level indicating that, on occasions when adolescents experienced less favorable treatment by fathers than usual, they reported more depressive symptoms and risky behavior. However, some of these effects were moderated by youth age and cultural socialization. For example, adolescents who experienced relatively less paternal warmth than their siblings also reported poorer adjustment, but this effect did not emerge for young adults; such an effect also was significant for unfavored youth with stronger but not weaker cultural orientations.

    Lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) is an independent risk factor of cardiovascular disease and a target of treatment. Lp-PLA(2) levels in children have not been previously reported. The effect of statin therapy on Lp-PLA(2) mass and activity in children with familial hypercholesterolemia (FH) is also not known. Lp-PLA(2) mass and activity levels were measured at baseline and after 2 years in 178 children with FH randomized to pravastatin or placebo and in 78 unaffected and untreated siblings. At the end of the randomized period, all FH children were then placed on pravastatin for an additional 2 years, and Lp-PLA(2) mass and activity levels were correlated with changes in carotid intima-media thickness during 4 years of follow-up. Baseline levels of Lp-PLA(2) mass and activity were significantly greater in children with FH compared with unaffected siblings (mass: 240.3 ± 41.6 vs 222.1 ± 36.5 ng/mL, P = .002; activity: 205.7 ± 41.6 vs 124.3±23.0 nmol/min/mL, P vs 231.5 ± 34.8 ng/mL, P = .001) and activity (178.8 ± 37.3 vs 206.2 ± 33.5 nmol/min/mL, P children with heterozygous FH compared with unaffected siblings and are significantly reduced by pravastatin therapy.

    This study examined the helpfulness of coping strategies and the relative importance of mental health services in coping with schizophrenia from the perspective of siblings. This article presents selected survey data from a national study of 746 respondents that investigated the impact of schizophrenia on siblings' lives. The authors developed the Friedrich-Lively Instrument to Assess the Impact of Schizophrenia on Siblings (FLIISS), a closed-ended questionnaire that included questions about coping strategies and mental health services. Respondents identified services for the ill sibling, including symptom control, adequate housing, and long-term planning, as more important than direct services for themselves. The top-ranked coping strategies were education about schizophrenia, a supportive family, and seeing the ill sibling suffer less because symptoms were controlled. Understanding that families were not to blame for schizophrenia was the most helpful coping strategy for nearly three-fourths of siblings. Siblings had little contact with providers in the past; yet the majority of siblings wanted providers to be available to answer questions and clarify their role in future care. At the time of the study, respondents provided social support and helped with crises, but few coordinated the total care. Siblings identified multiple ways that providers can support and assist them in coping with the impact of schizophrenia. Education and support for siblings without schizophrenia and services for their ill siblings will become increasingly important for the well-being of siblings as they are faced with the responsibility of being the primary caregivers in the future.

    Investigating the impact of Angelman syndrome on the sibling relationship. This study explored differences in sibling relationships between children with a typically-developing sibling (n = 55) and children with a sibling with Angelman syndrome (n = 44). Sibling relationships were compared on four factors and 16 sub-scales of the Sibling Relationship Questionnaire-Revised. Results showed significant differences in mean scores on each of the four factors (i.e. Warmth/Closeness, Conflict, Rivalry and Dominance/Nurturance) and most of the sub-scales. ANCOVAs showed that demographic variables (number of siblings, living in a two-parent vs single parent household, gender, participant's age, place of residence) did not influence significant differences in sibling relationships between the two groups. Having a brother or sister with Angelman syndrome may influence the way in which the sibling perceives the sibling relationship. This may have important implications for family-centred intervention for this population.

  18. Galaxy halo expansions: a new biorthogonal family of potential-density pairs

    Efficient expansions of the gravitational field of (dark) haloes have two main uses in the modelling of galaxies: first, they provide a compact representation of numerically constructed (or real) cosmological haloes, incorporating the effects of triaxiality, lopsidedness or other distortion. Secondly, they provide the basis functions for self-consistent field expansion algorithms used in the evolution of N-body systems. We present a new family of biorthogonal potential-density pairs constructed using the Hankel transform of the Laguerre polynomials. The lowest order density basis functions are double-power-law profiles cusped like ρ ˜ r-2+1/α at small radii with asymptotic density fall-off like ρ ˜ r-3-1/(2α). Here, α is a parameter satisfying α ≥ 1/2. The family therefore spans the range of inner density cusps found in numerical simulations, but has much shallower - and hence more realistic - outer slopes than the corresponding members of the only previously known family deduced by Zhao and exemplified by Hernquist & Ostriker. When α = 1, the lowest order density profile has an inner density cusp of ρ ˜ r-1 and an outer density slope of ρ ˜ r-3.5, similar to the famous Navarro, Frenk & White (NFW) model. For this reason, we demonstrate that our new expansion provides a more accurate representation of flattened NFW haloes than the competing Hernquist-Ostriker expansion. We utilize our new expansion by analysing a suite of numerically constructed haloes and providing the distributions of the expansion coefficients.

    Full Text Available Two pairs of siblings with myasthenia gravis, belonging to two different families, are reported. This is the only record of familial myasthenia during the past twenty years, in a total of 145 patients seen at the Neurological Clinic of the São Paulo Medical School. In spite of the fact that myasthenia gravis does not show hereditary characteristics, the peculiar features of the four cases justify the present report. The two pairs of siblings were born from non myasthenic nor consanguineous parents. The disease started at birth showing bilateral partial eyelid ptosis in all patients. The course of the illness has been favorable. There was no thymoma.

    O' Brien, Irene; Duffy, Anita; Nicholl, Honor

    Childhood illness can have a significant impact on families, particularly on the ill child's siblings. There is a dearth of published literature focusing on the needs of siblings of ill children. This literature review aims to provide an overview of the current healthcare literature in relation to the impact of childhood chronic illness or disability on siblings. A literature review was undertaken by searching the databases CINAHL, PsycINFO, ProQuest and Cochrane Library for relevant articles in English using the search terms: 'siblings', 'chronic illness', 'disability', 'cancer', 'sibling relations', 'sibling adjustment', 'coping', 'family-centred care', 'sibling interventions', 'camps', 'autism', 'Down's syndrome'. Seventeen research studies in total were reviewed. This review focuses on three sibling groups related to children suffering from autism, cancer and Down's syndrome, and are discussed under the following headings: sibling adjustment; family functioning and sibling's coping resources; and intervention programmes. The literature revealed that siblings of children with Down's syndrome were well adjusted to living with their brother or sister. However, there was conflicting information on the adjustment of siblings of children with cancer and autism. An awareness of the harmful effect that living with childhood illness and disability can have on some siblings is essential to enable healthcare professionals to provide supportive interventions to protect siblings' physical and emotional wellbeing.

    This study examined concordance in the attachment strategies of school-aged siblings with reference to environmental risk in terms of poverty and maltreatment. It also investigated the effect of child maltreatment and maternal mental illness on children's psychosocial functioning in terms of the Dynamic-Maturational Model of Attachment and Adaptation (DMM) including unresolved trauma and the DMM Depressed modifier. The attachment strategies of 30 sibling pairs, aged 5-14 years, were assessed using the School-age Assessment of Attachment (SAA). Unlike most previous studies, this study included siblings from large families of two to six children. The main finding was that as environmental risk increases, the diversity of sibling attachment strategies decreases with greater recourse to the DMM Type A3-6 and A/C strategies. Unlike previous studies, the highest level of concordance was found in sibling pairs with the opposite gender. Boys whose mothers had a history of mental illness were significantly more likely than girls to be assessed with the DMM-depression modifier. As danger increases, children in the same family experience more of the same childhood. Further research should focus on single case, intra-familial studies to build a systemic model of the shared environment. Research should also evaluate the effects of environmental risk compared with size of the sibling group on children's attachment strategies. The clinical implications point to the importance of assessing all children in the family using a model built around functional formulation rather than diagnosing the symptoms of a particular child.

    2006-01-01

    Full Text Available Abstract Background Schizophrenia aggregates in families and accurate diagnoses are essential for genetic studies of schizophrenia. In this study, we investigated whether siblings of patients with schizophrenia can be identified as free of any psychotic disorder using only register information. We also analyzed the emergence of psychotic disorders among siblings of patients with schizophrenia during seven to eleven years of follow-up. Methods A genetically homogenous population isolate in north-eastern Finland having 365 families with 446 patients with a diagnosis of schizophrenia was initially identified in 1991 using four nationwide registers. Between 1998 and 2002, 124 patients and 183 siblings in 110 families were contacted and interviewed using SCID-I, SCID-II and SANS. We also compared the frequency of mental disorders between siblings and a random population comparison group sample. Results Thirty (16% siblings received a diagnosis of psychotic disorder in the interview. 14 siblings had had psychotic symptoms already before 1991, while 16 developed psychotic symptoms during the follow-up. Over half of the siblings (n = 99, 54% had a lifetime diagnosis of any mental disorder in the interview. Conclusion Register information cannot be used to exclude psychotic disorders among siblings of patients with schizophrenia. The high rate of emergence of new psychotic disorders among initially healthy siblings should be taken into account in genetic analysis.

    To compare the risks of admission to hospital for any type of psychiatric disorder and for four specific psychiatric disorders among adults who as children were evacuated to Swedish foster families during the second world war and their non-evacuated siblings, and to evaluate whether these risks differ between the sexes. Cohort study. National child evacuation scheme in Finland during the second world war. Children born in Finland between 1933 and 1944 who were later included in a 10% sample of the 1950 Finnish census ascertained in 1997 (n = 45,463; women: n = 22,021; men: n = 23,442). Evacuees in the sample were identified from war time government records. Adults admitted to hospital for psychiatric disorders recorded between 1971 and 2011 in the Finnish hospital discharge register. We used Cox proportional hazards models to estimate the association between evacuation to temporary foster care in Sweden during the second world war and admission to hospital for a psychiatric disorder between ages 38 and 78 years. Fixed effects methods were employed to control for all unobserved social and genetic characteristics shared among siblings. Among men and women combined, the risk of admission to hospital for a psychiatric disorder did not differ between Finnish adults evacuated to Swedish foster families and their non-evacuated siblings (hazard ratio 0.89, 95% confidence interval 0.64 to 1.26). Evidence suggested a lower risk of admission for any mental disorder (0.67, 0.44 to 1.03) among evacuated men, whereas for women there was no association between evacuation and the overall risk of admission for a psychiatric disorder (1.21, 0.80 to 1.83). When admissions for individual psychiatric disorders were analyzed, evacuated girls were significantly more likely than their non-evacuated sisters to be admitted to hospital for a mood disorder as an adult (2.19, 1.10 to 4.33). The Finnish evacuation policy was not associated with an increased overall risk of admission to hospital

    To evaluate the impact of sodium benzoate and dextromethorphan treatment on patients with the attenuated form of nonketotic hyperglycinemia. Families were recruited with 2 siblings both affected with attenuated nonketotic hyperglycinemia. Genetic mutations were expressed to identify residual activity. The outcome on developmental progress and seizures was compared between the first child diagnosed and treated late with the second child diagnosed at birth and treated aggressively from the newborn period using dextromethorphan and benzoate at dosing sufficient to normalize plasma glycine levels. Both siblings were evaluated with similar standardized neurodevelopmental measures. In each sibling set, the second sibling treated from the neonatal period achieved earlier and more developmental milestones, and had a higher developmental quotient. In 3 of the 4 sibling pairs, the younger sibling had no seizures whereas the first child had a seizure disorder. The adaptive behavior subdomains of socialization and daily living skills improved more than motor skills and communication. Early treatment with dextromethorphan and sodium benzoate sufficient to normalize plasma glycine levels is effective at improving outcome if used in children with attenuated disease with mutations providing residual activity and when started from the neonatal period.

    Higher early-life intelligence is associated with a reduced risk of mortality in adulthood, though this association is apparently hardly attenuated when accounting for early-life socio-economic status (SES). However, the use of proxy measures of SES means that residual confounding may underestimate this attenuation. In the present study, the potential confounding effect of early-life SES was instead accounted for by examining the intelligence-mortality association within families. The association between early-life intelligence and mortality in adulthood was assessed in 727 members of the 6-Day Sample of the Scottish Mental Survey 1947 and, for the first time, 1580 of their younger siblings. These individuals were born between 1936 and 1958, and were followed up into later life, with deaths recorded up to 2015. Cox regression was used to estimate the relative risk of mortality associated with higher IQ scores after adjusting for shared family factors. A standard-deviation advantage in IQ score was associated with a significantly reduced mortality risk [hazard ratio = 0.76, p family factors [hazard ratio = 0.79, p = 0.002, 95% CI (0.68-0.92)]. Although somewhat conservative, adjusting for all variance shared by a family avoids any potential residual confounding of the intelligence-mortality association arising from the use of proxy measures of early-life SES. The present study demonstrates that the longevity associated with higher early-life intelligence cannot be explained by early-life SES or within-family factors. © The Author 2017; Published by Oxford University Press on behalf of the International Epidemiological Association

    2012-05-01

    Psychosocial adjustment in siblings of children with autism whose families were using a home-based, applied behavior analysis (ABA) program was compared to that of siblings in families who were not using any intensive autism intervention. Data gathered from parents, siblings and teachers indicated that siblings in ABA families experienced neither significant drawbacks nor benefits in terms of their behavioral adjustment, sibling relationship quality and self-concept compared to control group siblings, either during or following intervention use. Parents and siblings perceived improvements in sibling interaction since the outset of ABA, with parents somewhat more positive in their views than were siblings. Social support was associated with better sibling outcomes in all groups. Implications for supporting families using ABA are considered.

    Current discussions of offspring begging typically assume either that it is a signal directed at parents or that it represents a form of scramble competition to gain access to them. However, offspring might also display to inform nest mates that they will contest the next food item to be delivered; in other words, begging (possibly in the absence of parents) might serve purely as a form of negotiation among siblings. Here, we develop a game-theoretical model of this possibility. We assume tha...

    Determining the fitness consequences of sibling interactions is pivotal for understanding the evolution of family living, but studies investigating them across lifetime are lacking. We used a large demographic dataset on preindustrial humans from Finland to study the effect of elder siblings on key life-history traits. The presence of elder siblings improved the chances of younger siblings surviving to sexual maturity, suggesting that despite a competition for parental resources, they may help rearing their younger siblings. After reaching sexual maturity however, same-sex elder siblings' presence was associated with reduced reproductive success in the focal individual, indicating the existence of competition among same-sex siblings. Overall, lifetime fitness was reduced by same-sex elder siblings' presence and increased by opposite-sex elder siblings' presence. Our study shows opposite effects of sibling interactions depending on the life-history stage, and highlights the need for using long-term fitness measures to understand the selection pressures acting on sibling interactions.

    As various forms of interpersonal family violence receive more attention in the literature, sibling abuse is still in the background. Despite the increasing knowledge about the prevalence, causes, and effects of sibling abuse, many of us continue to relegate it to a childhood occurrence. Sibling abuse symptoms continue to go unrecognized and its demoralizing effects continue to be ignored (Wiehe, 1990). Minimization and denial of sibling abuse have also contributed to constraining the extent ...

  17. Pairing symmetries of several iron-based superconductor families and some similarities with cuprates and heavy-fermions

    Directory of Open Access Journals (Sweden)

    Das Tanmoy

    2012-03-01

    Full Text Available We show that, by using the unit-cell transformation between 1 Fe per unit cell to 2 Fe per unit cell, one can qualitatively understand the pairing symmetry of several families of iron-based superconductors. In iron-pnictides and iron-chalcogenides, the nodeless s±-pairing and the resulting magnetic resonance mode transform nicely between the two unit cells, while retaining all physical properties unchanged. However, when the electron-pocket disappears from the Fermi surface with complete doping in KFe2As2, we find that the unit-cell invariant requirement prohibits the occurrence of s±-pairing symmetry (caused by inter-hole-pocket nesting. However, the intra-pocket nesting is compatible here, which leads to a nodal d-wave pairing. The corresponding Fermi surface topology and the pairing symmetry are similar to Ce-based heavy-fermion superconductors. Furthermore, when the Fermi surface hosts only electron-pockets in KyFe2-xSe2, the inter-electron-pocket nesting induces a nodeless and isotropic d-wave pairing. This situation is analogous to the electron-doped cuprates, where the strong antiferromagnetic order creates similar disconnected electron-pocket Fermi surface, and hence nodeless d-wave pairing appears. The unit-cell transformation in KyFe2-xSe2 exhibits that the d-wave pairing breaks the translational symmetry of the 2 Fe unit cell, and thus cannot be realized unless a vacancy ordering forms to compensate for it. These results are consistent with the coexistence picture of a competing order and nodeless d-wave superconductivity in both cuprates and KyFe1.6Se2.

    Twin studies have shown that criminal behavior (CB) is influenced by both genetic and shared environmental factors. Could these results be replicated using full-siblings and half-siblings? In 911 009 full-siblings reared together (FSRT), 41 872 half-siblings reared together (HSRT) and 52 590 half-siblings reared apart (HSRA), CB was assessed from the Swedish Crime Register. Modeling, including testing for age differences and rearing status, was performed using the OpenMx package. Five sibling models were fitted examining FSRT and HSRT 0-2 years different in age, and both FSRT and HSRT, and FSRT, HSRT and HSRA 0-10 years different in age with and without a specified shared environment indexing age differences. Heritability estimates for CB ranged from 33 to 55% in females and 39 to 56% in males, similar to those found in our prior twin study on the same population. Estimates for the shared environment varied from 1 to 14% in females and 10 to 23% in males, lower than those estimated in the twin study. The specified shared environment indexed by sibling age differences was significant in all models tested. Heritability estimates for CB from full- and half-siblings closely approximated those found from twins in the same population, validating the twin method. Shared environmental estimates were lower, suggesting the presence of shared environmental factors for CB specific to twins. When rearing status can be assessed, full- and half-siblings offer an additional method for assessing the role of genetic and environmental factors in complex disorders. However, age differences in siblings may need to be included in the models.

    In dementia care, a large number of treatment decisions are made by family carers on behalf of their family member who lacks decisional capacity; advance care planning can support such carers in the decision-making of care goals. However, given the relative importance of advance care planning in dementia care, the prevalence of advance care planning in dementia care is poor. To evaluate the effectiveness of advance care planning with family carers in dementia care homes. Paired cluster randomized controlled trial. The intervention comprised a trained facilitator, family education, family meetings, documentation of advance care planning decisions and intervention orientation for general practitioners and nursing home staff. A total of 24 nursing homes with a dementia nursing category located in Northern Ireland, United Kingdom. Family carers of nursing home residents classified as having dementia and judged as not having decisional capacity to participate in advance care planning discussions. The primary outcome was family carer uncertainty in decision-making about the care of the resident (Decisional Conflict Scale). There was evidence of a reduction in total Decisional Conflict Scale score in the intervention group compared with the usual care group (-10.5, 95% confidence interval: -16.4 to -4.7; p planning was effective in reducing family carer uncertainty in decision-making concerning the care of their family member and improving perceptions of quality of care in nursing homes. Given the global significance of dementia, the implications for clinicians and policy makers include them recognizing the importance of family carer education and improving communication between family carers and formal care providers.

    2012-07-01

    This qualitative study explored the experiences of Latino siblings of children with developmental disabilities. Parents and typically developing siblings from 15 Latino families with a child with a developmental disability participated in separate interviews. Using consensual qualitative research methodology, domains reflecting siblings' relationships, emotional experiences and communication about the disability were identified. The child's need for caregiving was a prominent topic in the sibling and parent narratives. Parents reported concerns about siblings' experience of differential treatment, whereas siblings reported concerns about restricted social activities because of their brother/sister. Including multiple informants revealed commonalities and differences in parents' and siblings' perspectives on the impact of a child's disability. The importance of considering sibling adaptation in sociocultural context is discussed. © 2011 Blackwell Publishing Ltd.

    Research addressing genetic and environmental determinants to antisocial behaviour suggests substantial variability across studies. Likewise, evidence for etiologic gender differences is mixed, and estimates might be biased due to assortative mating. We used longitudinal Swedish total population registers to estimate the heritability of objectively measured violent offending (convictions) in classic twin (N = 36,877 pairs), adoptee-parent (N = 5,068 pairs), adoptee-sibling (N = 10,610 pairs), and sibling designs (N = 1,521,066 pairs). Type and degree of assortative mating were calculated from comparisons between spouses of siblings and half-siblings, and across consecutive spouses. Heritability estimates for the liability of violent offending agreed with previously reported heritability for self-reported antisocial behaviour. While the sibling model yielded estimates similar to the twin model (A ≈ 55%, C ≈ 13%), adoptee-models appeared to underestimate familial effects (A ≈ 20-30%, C ≈ 0%). Assortative mating was moderate to strong (r (spouse) = 0.4), appeared to result from both phenotypic assortment and social homogamy, but had only minor effect on variance components. Finally, we found significant gender differences in the etiology of violent crime.

Foram realizadas sessões de observação de interações, e aplicação de instrumentos de auto-relato; os cuidadores responderam escalas para avaliação do apoio social. Os resultados sugeriram diferença no comportamento de ajudante do irmão com desenvolvimento típico, com taxa de ocorrência maior para G1. Nas escalas, houve diferença estatisticamente significativa na Escala de Apoio à Maternidade/Paternidade, revelando-se menor apoio para G1. Especula-se que, como as famílias do G1 recebem menor apoio deste nível, há maior demanda de ajuda requerida pelo filho deficiente, que pode ser suprida pelos irmãos menores com desenvolvimento típico, que desempenham o papel de ajudante em maior escala que os adultos.The purpose of the present study was: (a To describe the relationship in sibling's dyads, separated in two groups - G1, with pre-adolescent mentally retarded sibling, and G2, with this adult sibling; (b To compare the performance of both groups in the interactions; and (3 To evaluate differences in the relationships between the groups when family social support is taken into account. Sessions of sibling's interactions were videotaped, and self-report instruments were used. The caretakers answered scales of social support. Results suggested differences concerning the behavior of the helper of the sibling with characteristic development, with highest occurrence in G1. Scales' results indicated statistically significant difference for the Parenting Support from Family/Friends Scale, showing less support for G1. It is possible to suggest that because families from G1 have less support

    This study extends research on sibling conflict strategies and outcomes by examining unique and interactive associations with age, relative birth order, sibling relationship quality, and caregivers' interventions into conflict. Each of 62 sibling dyads (older sibling mean age = 8.39 years; younger sibling mean age = 6.06 years) discussed 1 recurring conflict alone (dyadic negotiation) and a 2nd conflict with their primary parental caregiver (triadic negotiation). Negotiations were coded for children's conflict strategies, outcomes, and caregiver interventions; each family member provided ratings of sibling relationship quality. Results revealed that age was associated with siblings' constructive strategies, particularly in the dyadic negotiation. With age controlled, younger siblings referred more frequently to their own perspective. Caregivers' future orientation in the triadic negotiation was associated with children's future orientation in the dyadic negotiation; however, this association was most evident when sibling relationship quality was high. Similarly, caregivers' past orientation was positively associated with dyadic compromise, especially when relationship quality was high. Results reveal the value of simultaneously considering associations among parental, affective, and developmental correlates of sibling conflict strategies.

    This document contains 3 reports. In the first report four siblings are presented who had infantile pyloric stenosis unequivocally demonstrated when pyloromyotomy was performed in the early neonatal period. Their father had symptoms of stenosis as an infant but he was treated medically and it cannot be stated with certainty that he had the disease. Blood groups, determined for the four children and their parents, were not unusual. Chromosome karyotypes, obtained from peripheral blood cultures, were apparently normal. In the second report, a case study of a patient exhibiting side effects due to chloroquine used in the treatment of lupus vulgaris is presented. In the third report, in a survey for hemoglobinopathies in Nagasaki, Japan four members in two generations of a Japanese family were found to have an abnormal hemoglobin, which on detailed chemical analyses was demonstrated to be hemoglobin E. The question of prior introduction of the gene into Japan from Southeast Asia versus independent mutation is briefly discussed. 70 references, 4 figures, 5 tables.

    Full Text Available Rare inherited variations in multiplex families with autism spectrum disorder (ASD are suggested to play a major role in the genetic etiology of ASD. To further investigate the role of rare inherited variations, we performed whole-exome sequencing (WES in two families, each with three affected siblings. We also performed a two-stage follow-up case-control study in a Japanese population. WES of the six affected siblings identified six novel rare missense variations. Among these variations, CLN8 R24H was inherited in one family by three affected siblings from an affected father and thus co-segregated with ASD. In the first stage of the follow-up study, we genotyped the six novel rare missense variations identified by WES in 241 patients and 667 controls (the Niigata sample. Only CLN8 R24H had higher mutant allele frequencies in patients (1/482 compared with controls (1/1334. In the second stage, this variation was further genotyped, yet was not detected in a sample of 309 patients and 350 controls (the Nagoya sample. In the combined Niigata and Nagoya samples, there was no significant association (odds ratio = 1.8, 95% confidence interval = 0.1-29.6. These results suggest that CLN8 R24H plays a role in the genetic etiology of ASD, at least in a subset of ASD patients.

  12. Siblings and children's time use in the United States

    2017-11-01

    Full Text Available Background: Eighty-two percent of children under age 18 live with at least one sibling, and the sibling relationship is typically the longest-lasting family relationship in an individual's life. Nevertheless, siblings remain understudied in the family demography literature. Objective: We ask how having a sibling structures children's time spent with others and in specific activities, and how children's time and activities with siblings vary by social class, gender, and age. Methods: We use time diary data from the US Panel Study of Income Dynamics' Child Development Supplement (PSID-CDS, comparing the time use of children with and without siblings and presenting regression-adjusted descriptive statistics on patterns among those with siblings. Results: Children with siblings spend about half of their discretionary time engaged with siblings. They spend less time alone with parents and more time in unstructured play than those without siblings. Brothers and more closely spaced siblings spend more time together and more time in unstructured play. For example, boys with at least one brother spend five more hours per week with their siblings and over three more hours per week in unstructured play than boys with no brothers. Conclusions: The presence and characteristics of siblings shape children's time use in ways that may have implications for child development. Contribution: This is the first study to use children's time diary data to examine how the presence and characteristics of siblings structure ways in which children spend their time. This contributes to our broader understanding of sibling relationships and family dynamics.

    2006-06-01

    The aim of this study was to examine the experience of the first generation of sibling advocates in Hong Kong. A qualitative approach was adopted and six sibling advocates of people with intellectual disabilities from one non-government organization were interviewed. Data were analyzed using a constant comparative method and content analysis. Findings revealed that the six participants were reactive in the process of taking up the caregiver responsibility and they performed three functions: to advocate for more service provision, to improve service quality, and to facilitate communication between individual service units and family members of people with intellectual disabilities. All of the participants expressed that they needed support from service providers when they tried to function as the sibling advocates. Strategies to promote the involvement of siblings of people with intellectual disabilities as advocates are discussed and it is expected that more siblings of people with intellectual disabilities will be supported to have a higher level of involvement in advocacy.

    Elevated stress perception and depression commonly co-occur, suggesting that they share a common neurobiology. Cortical thickness of the rostral middle frontal gyrus (RMFG), a region critical for executive function, has been associated with depression- and stress-related phenotypes. Here, we examined whether RMFG cortical thickness is associated with these phenotypes in a large family-based community sample. RMFG cortical thickness was estimated using FreeSurfer among participants (n = 879) who completed the ongoing Human Connectome Project. Depression-related phenotypes (i.e. sadness, positive affect) and perceived stress were assessed via self-report. After accounting for sex, age, ethnicity, average whole-brain cortical thickness, twin status and familial structure, RMFG thickness was positively associated with perceived stress and sadness and negatively associated with positive affect at small effect sizes (accounting for 0.2-2.4% of variance; p-fdr: 0.0051-0.1900). Perceived stress was uniquely associated with RMFG thickness after accounting for depression-related phenotypes. Further, among siblings discordant for perceived stress, those reporting higher perceived stress had increased RMFG thickness (P = 4 × 10 -7 ). Lastly, RMFG thickness, perceived stress, depressive symptoms, and positive affect were all significantly heritable, with evidence of shared genetic and environmental contributions between self-report measures. Stress perception and depression share common genetic, environmental, and neural correlates. Variability in RMFG cortical thickness may play a role in stress-related depression, although effects may be small in magnitude. Prospective studies are required to examine whether variability in RMFG thickness may function as a risk factor for stress exposure and/or perception, and/or arises as a consequence of these phenotypes. © 2017 John Wiley & Sons Ltd and International Behavioural and Neural Genetics Society.

    Screening of mutations in the paired box 3 (PAX3) gene in three generations of a Turkish family with Waardenburg syndrome type 1 (WS1). WS1 was diagnosed in a 13-month-old girl according to the WS Consortium criteria. Detailed family history of the proband revealed eight affected members in three generations. Routine clinical and audiological examination and ophthalmologic evaluation were performed on eight affected and five healthy members of the study family. Dystopia canthorum was detected in all affected patients; however, a brilliant blue iris was present in five patients who also had mild retinal hypopigmentation. Genomic DNA was extracted from the peripheral blood of affected and unaffected individuals in the family as well as 50 unrelated healthy volunteers. All coding exons and adjacent intronic regions of PAX3 were sequenced directly. A novel missense heterozygous c.788T>G mutation was identified in eight patients. This nucleotide alteration was not found in unaffected members of the study family or in the 50 unrelated control subjects. The mutation causes V263G amino-acid substitution in the homeodomain of the PAX3 protein, which represents the 45(th) residue of helix 3. We identified a novel missense c.788T>G mutation in PAX3 in a family with Waardenburg syndrome with intrafamilial phenotypic heterogeneity.

    2012-01-01

    This study investigated links between interparental conflict appraisals (specifically threat and self-blame), sibling relationship quality (positive and negative dimensions), and anxiety in sibling pairs comprised of an adolescent and a younger sibling close in age. Sibling relationship quality was measured through behavioral observation. Links between self-blame and anxiety were moderated by sibling relationship quality. In older siblings, positive behavior with a sibling was associated with an attenuated relation between self-blame and anxiety. A paradoxical moderating effect was found for negative interactions; for both younger and older siblings, a relation between self-blame and anxiety was weakened in the presence of sibling negativity. Results offered support for theorized benefits of sibling relationship quality in helping early adolescents adjust to conflict between parents. PMID:24244080

    The nonhomologous end-joining pathway is a major means for repairing double-strand breaks (DSBs) in all mitotic cell types. This repair pathway is also the only efficient means for resolving DSB intermediates in V(D)J recombination, a lymphocyte-specific genome rearrangement required for assembly of antigen receptors. A role for polymerases in end-joining has been well established. They are a major factor in determining the character of repair junctions but, in contrast to 'core' end-joining factors, typically appear to have a subtle impact on the efficiency of end-joining. Recent work implicates several members of the Pol X family in end-joining and suggests surprising complexity in the control of how these different polymerases are employed in this pathway.

    Mutations in the TBC1D24 gene were first reported in an Italian family with a unique epileptic phenotype consisting of drug-responsive, early-onset idiopathic myoclonic seizures. Patients presented with isolated bilateral or focal myoclonia, which could evolve to long-lasting attacks without loss of consciousness, with a peculiar reflex component, and were associated with generalized tonic-clonic seizures. This entity was named "familial infantile myoclonic epilepsy" (FIME). More recently, TBC1D24 mutations have been shown to cause a variable range of disorders, including epilepsy of various seizure types and severity, non-syndromic deafness, and DOORS syndrome. We report on the electro-clinical features of two brothers, born to first-cousin parents, affected with infantile-onset myoclonic epilepsy. The peculiar epileptic presentation prompted us to perform direct sequencing of the TBC1D24 gene. The patients had very early onset of focal myoclonic fits with variable topography, lasting a few minutes to several hours, without loss of consciousness, which frequently evolved to generalized myoclonus or myoclonic status. Reflex myoclonia were noticed in one patient. Neurological outcome was marked by moderate intellectual disability. Despite the high frequency of seizures, repeated EEG recordings showed normal background rhythm and rare interictal spikes and waves. We found a homozygous missense mutation, c.457G>A/p.Glu153Lys, in the two affected brothers. This observation combined with recent data from the literature, suggest that mutations in TBCD24 cause a pathological continuum, with FIME at the "benign" end and severe drug-refractory epileptic encephalopathy on the severe end. Early-onset myoclonic epilepsy with focal and generalized myoclonic seizures is a common characteristic of this continuum. Copyright © 2015 Elsevier B.V. All rights reserved.

    The purpose of this study was to empirically test if siblings of children with disability had higher levels of parent-reported behavioral and emotional functional impairment compared with a peer group of siblings residing with only typically developing children. This was a retrospective secondary analysis of data from the Medical Expenditure Panel Survey. We included only households with at least 2 children to ensure sibling relationships. Two groups of siblings were formed: 245 siblings resided in households with a child with disability and 6564 siblings resided in households with typically developing children. Parents responded to questions from the Columbia Impairment Scale to identify functional impairment in their children. On the basis of parent reports and after adjusting for sibling demographic characteristics and household background, siblings of children with disability were more likely than siblings residing with typically developing children to have problems with interpersonal relationships, psychopathological functioning, functioning at school, and use of leisure time (P siblings of children with disability classified with significant functional impairment was 16.0% at the first measurement period and 24.2% at the second (P siblings of typically developing children there was a smaller percentage increase from 9.5% to 10.3% (P mental health services and, as such, early assessment and interventions to limit increasing severity and short- to long-term consequences need to be addressed. Health care professionals need to consider a family-based health care approach for families raising children with disability.

    2009-12-01

    There is conflicting evidence about the impact of disability upon siblings, and very little research on the siblings of children with epilepsy. There is some evidence that siblings who have less accurate information exhibit more distress. The aim of this study was to assess siblings' response to having a brother or sister with epilepsy and to begin to develop information for them. Parents of children attending paediatric neurology outpatient departments were invited to participate in a pilot study. Parents who consented to take part were asked if they had previously received information for siblings. Parents and siblings participated in a semi-structured interview and siblings were also invited to submit a personal account of living with a brother or sister who had epilepsy. Twenty-five families with a child with epilepsy aged 2.5-15 years initially agreed to take part. None of the families stated that they had ever seen or received any information specifically for siblings. Fourteen siblings from the 25 families, aged 8-25 years, provided a personal account of what it was like living with a brother or sister with epilepsy. Siblings' accounts included both negative and positive feelings, and specifically feelings of care and love for their sibling. This initial study suggests that siblings of children with epilepsy have many positive but also early negative feelings. The results are limited by the size of the study, the fact that most siblings were older sisters, and the mean time since diagnosis was 6 years. Finally, it is hoped that the personal accounts collected in this study will be published for the benefit of other siblings of children with epilepsy.

    Several international jurisdictions allow family exemptions to graduated driver licensing passenger restrictions. The objective of this research was to examine differences in injury risk to US child passengers in crashes involving sibling versus non-sibling teen drivers, and to compare outcomes with crashes involving adult drivers. Insurance claim and telephone survey data were collected on 16 233 child passengers (representing 289 329 children) in 17 US jurisdictions. There was a trend toward higher restraint non-use by child passengers in the non-sibling group than in the sibling group (9.6% vs 4.7%; p = 0.08). Children in the sibling group had a 40% lower risk of injury than those in the non-sibling group (adjusted OR 0.60, 95% CI 0.40 to 0.90); however, injury risk was higher in the sibling group than in children traveling with adults (adjusted OR 1.57, 95% CI 1.09 to 2.26). Child passengers riding with sibling teen drivers may be safer than those riding with non-sibling teens, but not as safe as those riding with adult drivers.

    Using a randomized, intent-to-treat design, this pilot study examined the feasibility and short-term effects of Siblings Are Special ( SIBS ) with a sample of 54 low-income Latino families (91% Mexican-origin). Participants were older (M = 10.8 years; SD = .46) and younger siblings (M = 8.4 years; SD = 1.13), and their parents (94% biological mothers), who were randomly assigned within school to the intervention (n = 28) or no-attention control (n = 26) condition. The intervention condition included 12 weekly afterschool sessions (90 min each) for sibling pairs and 3 family nights for parents and siblings (2 hr each). SIBS was designed to enhance sibling relationships via 2 primary intervention targets: (a) children’s capacities that underlie positive sibling dynamics, including relationship skills, cognitions, and shared activities; and (b) parenting of siblings, specifically, enhancing positive guidance and involvement and discouraging authoritarian control. Pre- and posttest data were gathered from siblings and parents. Recruitment and implementation data revealed high rates of attendance and completion, and high ratings of parent satisfaction with the program. Further, analyses suggested the program had positive effects of small to modest magnitude on posttest measures of sibling and parent–child relationship quality, parenting of siblings, older siblings’ emotional efficacy, and parents’ depressive symptoms and parenting stress, controlling for pretest levels of all outcomes and family background characteristics. Discussion addresses the feasibility of sibling-focused programs with low-income Latino families and makes recommendations for future research.

    Previous studies have shown widespread multisystem degeneration in patients with sporadic amyotrophic lateral sclerosis who develop a total locked-in state and survive under mechanical ventilation for a prolonged period of time. However, the disease progressions reported in these studies were several years after disease onset. There have been no reports of long-term follow-up with brain imaging of patients with familial amyotrophic lateral sclerosis at an advanced stage of the disease. We report the cases of siblings with amyotrophic lateral sclerosis with homozygous deletions of the exon 5 mutation of the gene encoding optineurin, in whom brain computed tomography scans were followed up for more than 20 years. The patients were a Japanese brother and sister. The elder sister was 33 years of age at the onset of disease, which began with muscle weakness of her left lower limb. Two years later she required mechanical ventilation. She became bedridden at the age of 34, and died at the age of 57. A computed tomography scan of her brain at the age of 36 revealed no abnormality. Atrophy of her brain gradually progressed. Ten years after the onset of mechanical ventilation, atrophy of her whole brain, including the cerebral cortex, brain stem and cerebellum, markedly progressed. Her younger brother was 36 years of age at the onset of disease, which presented as muscle weakness of his left upper limb. One year later, he showed dysphagia and dysarthria, and tracheostomy ventilation was performed. He became bedridden at the age of 37 and died at the age of 55. There were no abnormal intracranial findings on brain computed tomography scans obtained at the age of 37 years. At the age of 48 years, computed tomography scans showed marked brain atrophy with ventricular dilatation. Subsequently, atrophy of the whole brain rapidly progressed as in his elder sister. We conclude that a homozygous deletion-type mutation in the optineurin gene may be associated with widespread

    We examined the extent to which three sibling structure variables number of siblings, birth order, and presence of an older sibling at school age are linked to the second language skills of bilingual children. The research questions were tested using an ethnically heterogeneous sample of 1209 bilingual children with German as a second language. Controlling for children’s age, sex, nationality, number of children’s books at home, family language and parental German language skills, hierarchical regression analyses showed an inverse relationship between the number of siblings and second language skills: the more siblings a child had, the lower was his/her second language proficiency. This relationship was mediated by attendance in early education institutions. Moreover, first-born siblings showed better second language skills than later born siblings. The current study revealed that the resource dilution model, i.e., the decrease in resources for every additional sibling, holds for second language acquisition. Moreover, the results indicate that bilingual children from families with several children benefit from access to early education institutions. PMID:26089806

    2001-01-01

    Although sibling relationships can be considered as one of the most durable and intensive relationships, not much research in developmental psychology and family research has been done on this issue. The strong focus on parents, more specifically on mothers, stood in the way of adequate conceptualization and understanding of the function and contribution of siblings to individual development and family interaction. In this contribution a conceptualization of sibling relationships is presented. Siblings as objects of aggressive and sexual feelings as well as the function of siblings in the family system, for example, as parentification and negative identity is emphasized. In addition, the different qualities of sibling relationships, for example, envy, rivalry, similarity, and difference, are emphasized. The function of siblings as love objects is stressed, and the role of siblings as support as well as teaching object is illustrated. Finally, it is emphasized that, similar to relationships between parents and child, the quality of sibling relationships changed over time and leads, for example, to a detachment between sibling relationships during adolescence.

    2013-01-01

    This study examined within-family stability in parents’ differential treatment of siblings from adolescence to young adulthood and the effect of differential treatment in young adulthood on grown siblings’ relationship quality. The author used longitudinal data on parent – child and sibling relations from the sibling sample of the National Longitudinal Study of Adolescent Health (N = 1,470 sibling dyads). Within-dyad fixed effects regression models revealed that the adolescent sibling who was closer to parents went on to be the young adult sibling who was closer to and received more material support from parents. Results from an actor – partner interdependence model revealed that differential parental financial assistance of young adult siblings predicted worse sibling relationship quality. These findings demonstrate the lasting importance of affect between parents and offspring earlier in the family life course and the relevance of within-family inequalities for understanding family relations.

    Full Text Available The aim of the current study is to examine the quality of sibling relationship in families with a sibling with substance misuse (SSU and compare the relationship to families with a sibling with no use (SNU. Thirty-six (36 families participated in the study (17 with SSU and 19 with SNU; N = 144. Semi-structured interviews were conducted with 40 siblings (20 SNU and 20 SSU; 18-31 years old in order to qualitatively investigate the characteristics of the sibling relationship. The siblings were not identified with any psychopathology, according to SCL-90R. Moreover, we considered the family cohesion and adaptability, as identified by the FACES III (administered to the whole sample and the family constellation (including number of children, birth order, gender, family size, family structure, years of substance misuse and socioeconomic level. The results of the thematic analysis seem to support Furman and Buhrmester’s (1985 framework, in the context of SNU families. Nevertheless, when considering families with SSU the framework is enriched with a new axis: Loss/mourning. The substance misuse seems to provoke an overturn of the representation of the sibling relationship: the behavioral changes (i.e. disengagement of the sibling with drug use are experienced as a loss by the sibling non user, thus triggering the psychological process of ‘mourning’. Moreover, in these families, the sibling with no drug use seem to experience differential parenting, they feel neglected, angry and they take up a parental role towards the SSU, whom they experience as “sensitive” and “vulnerable”.

    2018-06-18

    A central issue in visual and spoken word recognition is the lexical representation of complex words-in particular, whether the lexical representation of complex words depends on semantic transparency: Is a complex verb like understand lexically represented as a whole word or via its base stand, given that its meaning is not transparent from the meanings of its parts? To study this issue, a number of stimulus characteristics are of interest that are not yet available in public databases of German. This article provides semantic association ratings, lexical paraphrases, and vector-based similarity measures for German verbs, measuring (a) the semantic transparency between 1,259 complex verbs and their bases, (b) the semantic relatedness between 1,109 verb pairs with 432 different bases, and (c) the vector-based similarity measures of 846 verb pairs. Additionally, we include the verb regularity of all verbs and two counts of verb family size for 184 base verbs, as well as estimates of age of acquisition and age of reading for 200 verbs. Together with lemma and type frequencies from public lexical databases, all measures can be downloaded along with this article. Statistical analyses indicate that verb family size, morphological complexity, frequency, and verb regularity affect the semantic transparency and relatedness ratings as well as the age of acquisition estimates, indicating that these are relevant variables in psycholinguistic experiments. Although lexical paraphrases, vector-based similarity measures, and semantic association ratings may deliver complementary information, the interrater reliability of the semantic association ratings for each verb pair provides valuable information when selecting stimuli for psycholinguistic experiments.

    2017-04-01

    Adult siblings of individuals with intellectual and developmental disabilities (IDD) report struggling to navigate the adult disability service delivery system and collaborate with professionals. To date, though, it is unclear how professionals encourage sibling involvement and, accordingly, the facilitators and challenges in working with siblings. For this study, 290 professionals participated in a national web-based survey; participants answered three open-ended questions about ways to involve siblings, positive experiences with siblings, and challenges in working with siblings. Professionals reported person-level and systems-level supports to encourage sibling involvement. Also, professionals reported enjoying working with cohesive families of individuals with IDD and witnessing the benefits that siblings bring to their brothers and sisters with IDD. Challenges in working with siblings included: lack of sibling involvement, systemic barriers, and caregiving burden. Implications for future research and practice are discussed.

    2014-11-01

    There are few published research studies in which siblings of children with autism spectrum disorder (ASD) provide self-reports about their own behavioural and emotional problems and their sibling relationships. Reliance on parent reports may lead to incomplete conclusions about the experiences of siblings themselves. Siblings 7-17 years and their mothers from 94 families of children with ASD were recruited. Mothers reported on family demographics, the behavioural and emotional problems of their child with ASD, and on their own symptoms of depression. Siblings reported on their relationship with their brother or sister with ASD, and siblings 11+ years of age also self-reported on their behavioural and emotional problems. Compared with normative British data, siblings reported very slightly elevated levels of behavioural and emotional problems. However, none of the mean differences were statistically significant and all group differences were associated with small or very small effect sizes - the largest being for peer problems (effect size = 0.31). Regression analysis was used to explore family systems relationships, with sibling self-reports predicted by the behaviour problems scores for the child with ASD and by maternal depression. Maternal depression did not emerge as a predictor of siblings' self-reported sibling relationships or their behavioural and emotional problems. Higher levels of behaviour problems in the child with ASD predicted decreased warmth/closeness and increased conflict in the sibling relationship. These data support the general findings of recent research in that there was little indication of clinically meaningful elevations in behavioural and emotional problems in siblings of children with ASD. Although further research replication is required, there was some indication that sibling relationships may be at risk where the child with ASD has significant behaviour problems. © 2014 John Wiley & Sons Ltd.

    Objectives To examine whether the association between psychosocial factors at work and incident coronary heart disease (CHD) is explained by pre-employment factors such as family history of CHD, education, paternal social class, number of siblings and height. Methods A prospective cohort study of 6435 of British men aged 35–55 years at phase 1 (1985–1988) and free from prevalent CHD at phase 2 (1989–1990) was conducted. Psychosocial factors at work were assessed at phases 1 and 2 and mean scores across the two phases were used to determine long-term exposure. Selected pre-employment factors were assessed at phase 1. Follow-up for coronary death, first non-fatal myocardial infarction or definite angina between phase 2 and 1999 was based on clinical records (250 events, follow-up 8.7 years). Results Pre-employment factors were associated with risk for CHD: hazard ratio, HRs (95% CI) were 1.33 (1.03 to 1.73) for family history of CHD, 1.18 (1.05–1.32) for each quartile decrease in height, and marginally 1.16 (0.99–1.35) for each category increase in number of siblings. Psychosocial work factors predicted CHD: 1.72 (1.08–2.74) for low job control and 1.72 (1.10–2.67) for low organisational justice. Adjustment for pre-employment factors changed these associations by 4.1% or less. Conclusions In this well-characterised occupational cohort of British men, the association between psychosocial factors at work and CHD was largely independent of family history of CHD, education, paternal education and social class, number of siblings and height.

    2005-01-01

    Sibling relationships may be relevant to the development of anorexia nervosa (AN), yet little research has focused on this aspect of the disorder. A narrative study of four women in various stages of recovery from AN is described and results relevant to sibling relationships are presented, enriched by published anecdotes and case studies. The anorexic interviewees described much antagonism and rivalry and little warmth and intimacy between themselves and their siblings. They seemed to feel they did not belong sufficiently in their families and other social settings despite a strong desire to belong. The sample is small, reports subjective and retrospective and no control group was included. It is suggested that anorexic girls often feel emotionally isolated from and misunderstood by siblings, who may have much to contribute to the process of therapy and recovery.

    Full Text Available The birth of a disabled child is a critical event that places all the members of the family in a condition of great vulnerability. When talking about families with a disabled child, attention is usually focused on the parents. Siblings tend to play a marginal role, as shown in the referred literature, in this specific field of investigation. Communicating diagnosis to siblings means involving them in the process of family change, making them active players rather than “spectators” in their own “existential niche”. Communication of diagnosis is a delicate, continuous process that has to be tackled appropriately, using targeted words and educational actions. Children need help in accepting and welcoming their disabled sibling, with all his/her characteristics (and deficits, through a balanced, pondered approach that includes both the dimension of co-development and the acknowledgement of problematic situations.

    Although sibling interactions play an important role in children’s early development, they are rarely studied in very young children with an older brother or sister with autism spectrum disorder (ASD). This study used a naturalistic, observational method to compare interactions between 18-month-old infants and their older sibling with ASD (n = 22) with a control group of 18-month-old infants and their typically developing (TD) older sibling (n = 29). In addition, role (a)symmetry and the influence of gender were evaluated. Sibling interactions in ASD-dyads were characterized by higher levels of negativity. Although somewhat less pronounced in ASD-dyads, role asymmetry was present in both groups, with the older child taking the dominant position. Finally, siblings pairs with an older sister were characterized by more positive behaviours. Since differences in sibling interactions may alter the developmental trajectories of both siblings, these early relationships should be taken into account in future ASD research and interventions.

    Autism spectrum disorder (ASD) aggregates in families, but the individual risk and to what extent this is caused by genetic factors or shared or nonshared environmental factors remains unresolved. To provide estimates of familial aggregation and heritability of ASD. A population-based cohort including 2,049,973 Swedish children born 1982 through 2006. We identified 37,570 twin pairs, 2,642,064 full sibling pairs, 432,281 maternal and 445,531 paternal half sibling pairs, and 5,799,875 cousin pairs. Diagnoses of ASD to December 31, 2009 were ascertained. The relative recurrence risk (RRR) measures familial aggregation of disease. The RRR is the relative risk of autism in a participant with a sibling or cousin who has the diagnosis (exposed) compared with the risk in a participant with no diagnosed family member (unexposed). We calculated RRR for both ASD and autistic disorder adjusting for age, birth year, sex, parental psychiatric history, and parental age. We estimated how much of the probability of developing ASD can be related to genetic (additive and dominant) and environmental (shared and nonshared) factors. In the sample, 14,516 children were diagnosed with ASD, of whom 5689 had autistic disorder. The RRR and rate per 100,000 person-years for ASD among monozygotic twins was estimated to be 153.0 (95% CI, 56.7-412.8; rate, 6274 for exposed vs 27 for unexposed ); for dizygotic twins, 8.2 (95% CI, 3.7-18.1; rate, 805 for exposed vs 55 for unexposed); for full siblings, 10.3 (95% CI, 9.4-11.3; rate, 829 for exposed vs 49 for unexposed); for maternal half siblings, 3.3 (95% CI, 2.6-4.2; rate, 492 for exposed vs 94 for unexposed); for paternal half siblings, 2.9 (95% CI, 2.2-3.7; rate, 371 for exposed vs 85 for unexposed); and for cousins, 2.0 (95% CI, 1.8-2.2; rate, 155 for exposed vs 49 for unexposed). The RRR pattern was similar for autistic disorder but of slightly higher magnitude.We found support for a disease etiology including only additive genetic and

    A growing body of research indicates that siblings uniquely influence each other's health risk behaviors during adolescence and young adulthood. Mechanisms underlying these associations, however, are largely unknown because they are rarely tested directly. The present study addressed this gap by examining the role of sibling modeling in explaining changes in Mexican-origin youths' deviant and sexual risk behaviors over time. The sample included 380 Mexican-origin siblings (older sibling age: M = 21.18, SD = 1.59; younger sibling age: M = 18.19, SD = .46) from (N = 190) families. Participants provided self-reports of their sibling relationship qualities, including modeling, as well as their engagement in deviant and sexual risk-taking behaviors in two home interviews across a 2-year span. A series of residualized regression models revealed that younger siblings' perceptions of modeling moderated the links between older siblings' deviant and sexual risk behaviors and younger siblings' subsequent behaviors in those same domains. Specifically, high levels of modeling predicted stronger associations between older siblings' earlier and younger siblings' later risk behaviors controlling for younger siblings' earlier behaviors as well as variables that have been used as proxies for social learning in previous research. Social learning mechanisms, especially modeling, are salient processes through which older siblings transmit norms and expectations regarding participation in health risk behaviors. Future research should continue to explore the ways in which siblings influence each other because such processes are emerging targets for intervention and prevention.

    PURPOSE: Cancer and birth defects cluster in families more often than expected by chance, but the reasons are neither well known nor well studied. METHODS: From singletons born alive in Denmark between 1 January 1977 and 31 December 2007, we identified children who had no congenital malformations...... but had a full or half sibling with a congenital malformation (CM) diagnosed in the first year of life; this constituted the exposed group, while children whose siblings had no such condition constituted a reference group. We estimated cancer risks for children who had a full sibling or a half sibling...

    2015-07-01

    The potential of adult siblings to offer long-term support to a brother or sister with autism is rarely realized. To understand this, our study explores the expectations of social care among adult siblings. Using qualitative interviews, we spoke to 21 adult siblings about their family relationships and engagement with service delivery, met with 12 of their siblings with autism and talked to 12 social care staff. Siblings, although reflecting on the difficulties of growing up with someone who had autism, expressed a commitment towards their brother or sister. Most wanted involvement in their care. While some siblings described positive relationships with services, many felt marginalized. Practitioners largely confirmed their perceptions, while offering a justification for why they struggled to engage with adult siblings. By understanding the way relationships between siblings change over time, adult siblings' contribution to the lives of their disabled brother or sister can be better supported. © 2015 John Wiley & Sons Ltd.

    1997-01-01

    Sibling rivalry can be found in many families and frequently creates a stressful and challenging situation for parents. The arrival of a new baby often causes older siblings to feel displaced, frustrated, angry, and even unloved. Age, gender, personality and temperament, and parental behavior are factors that appear to influence the degree to which sibling rivalry occurs. Common reactions of older siblings to the birth of a new baby include aggression toward the newborn, behavioral regression, and attention seeking behavior, as well as independence and maturity. Anticipatory guidance is recommended to help parents adequately prepare their older child for the arrival of a new sibling. Strategies for managing sibling rivalry include open parent-child communication, equal treatment of siblings, non-intervention in sibling conflicts, distraction, and separation. Parents can minimize feelings of jealousy between siblings by providing a supportive, nurturing environment that allows each child to feel secure and loved.

  14. Perceptions of sibling relationships during middle childhood and adolescence.

    Buhrmester, D; Furman, W

    1990-10-01

    Children in grades 3, 6, 9, and 12 were administered the Sibling Relationship Questionnaire. Relationships were rated as progressively more egalitarian across the 4 grade groups, with adolescents reporting less dominance and nurturance by their older siblings than younger participants. Adolescents also reported less companionship, intimacy, and affection with siblings than younger participants reported. Levels of perceived conflict with younger siblings were moderately high across all 4 grades, whereas ratings of conflict with older siblings were progressively lower across the 4 grades. The findings suggested that sibling relationships: (a) become more egalitarian and less asymmetrical with age, (b) become less intense with age, and (c) encompass experiences that are partially determined by the child's standing in the family constellation.

    The purpose of this research project was to understand, primarily from the sibling perspective, the effect of a child's major burn injury on his or her sibling. A mixed method qualitative dominant design was implemented using the life story method for the qualitative portion. Additionally, the Sibling Relationship Questionnaire -Revised (SRQ-R) was used as a structured interview guide and for calculating scoring data to explore sibling relationship factors of warmth/closeness, rivalry, conflict, and relative status/power. Participants from 22 family cases (one or multiple family members) and 40 individuals were interviewed. To capture impact on the family over time, interviews began a minimum of two years post-burn. The central thematic pattern for the sibling relationship in families having a child with a major burn injury was that of normalization. Two components of normalization were described: areas of normalization and the process of adjustment. Areas of normalization were found in play and other activities, in school and work, and in family relations with siblings. The process of adjustment was varied and often gradual, involved school and work re-entry, and in some instances, seemed to change life perspective. Clinical implications in providing family-centered care can focus on promoting normalization by assessing and supporting siblings who may only be occasionally seen in the hospital or clinic.

Male siblings were at increased risk for sub-clinical anxiety problems during middle childhood. P...

  2. Caregiving, perceptions of maternal favoritism, and tension among siblings.

    Science.gov (United States)

    Suitor, J Jill; Gilligan, Megan; Johnson, Kaitlin; Pillemer, Karl

    2014-08-01

    Studies of later-life families have revealed that sibling tension often increases in response to parents' need for care. Both theory and research on within-family differences suggest that when parents' health declines, sibling relations may be affected by which children assume care and whether siblings perceive that the parent favors some offspring over others. In the present study, we explore the ways in which these factors shape sibling tension both independently and in combination during caregiving. In this article, we use data collected from 450 adult children nested within 214 later-life families in which the offspring reported that their mothers needed care within 2 years prior to the interview. Multilevel analyses demonstrated that providing care and perceiving favoritism regarding future caregiving were associated with sibling tension following mothers' major health events. Further, the effects of caregiving on sibling tension were greater when perceptions of favoritism were also present. These findings shed new light on the conditions under which adult children are likely to experience high levels of sibling tension during caregiving. Understanding these processes is important because siblings are typically the individuals to whom caregivers are most likely to turn for support when assuming care of older parents, yet these relationships are often a major source of interpersonal stress. © The Author 2013.

    Kendler, K S; Ohlsson, H; Sundquist, K; Sundquist, J

    2016-05-01

    Although drug abuse (DA) is strongly familial, with important genetic influences, we need to know more about the role of rearing environment in the risk for DA. To address this question, we utilized a high-risk adopted and non-adopted co-sibling control design. High-risk offspring had one or more biological parents registered for DA, alcohol use disorders or criminal behavior. Using Swedish registries, we identified 1161 high-risk full-sibships and 3085 high-risk half-sibships containing at least one member who was adopted-away and one member who was not. Registration for DA was via national criminal, medical and pharmacy registers. In Sweden, adoptive families are screened to provide high-quality rearing environment for adoptees. Controlling for parental age at birth and gender (and, in half-siblings, high-risk status of the other parent), risk for DA was substantially lower in the full- and half-siblings who were adopted v. not adopted [hazard ratios and 95% confidence intervals: 0.55 (0.45-0·69) and 0.55 (95% CI 0.48-0.63), respectively]. The protective effect of adoption on risk for DA was significantly stronger in the full- and half-sibling pairs with very high familial liability (two high-risk parents) and significantly weaker when the adoptive family was broken by death or divorce, or contained a high-risk parent. In both full- and half-sibling pairs, we found replicated evidence that rearing environment strongly impacts on risk for DA. High-quality rearing environments can substantively reduce risk for DA in those at high genetic risk.

  6. Sibling recognition and the development of identity: intersubjective consequences of sibling differentiation in the sister relationship.

    Science.gov (United States)

    Vivona, Jeanine M

    2013-01-01

    Identity is, among other things, a means to adapt to the others around whom one must fit. Psychoanalytic theory has highlighted ways in which the child fits in by emulating important others, especially through identification. Alternately, the child may fit into the family and around important others through differentiation, an unconscious process that involves developing or accentuating qualities and desires in oneself that are expressly different from the perceived qualities of another person and simultaneously suppressing qualities and desires that are perceived as similar. With two clinical vignettes centered on the sister relationship, the author demonstrates that recognition of identity differences that result from sibling differentiation carries special significance in the sibling relationship and simultaneously poses particular intersubjective challenges. To the extent that the spotlight of sibling recognition delimits the lateral space one may occupy, repeatedly frustrated desires for sibling recognition may have enduring consequences for one's sense of self-worth and expectations of relationships with peers and partners.

  8. On the Origins of Entrepreneurship: Evidence from Sibling Correlations

    DEFF Research Database (Denmark)

    Lindquist, Matthew J.; Sol, Joeri; Van Praag, Mirjam

    . We test this assumption and assess the importance of family background and neighborhood effects as determinants of entrepreneurship, by estimating sibling correlations in entrepreneurship. We find that between 20 and 50 percent of the variance in different entrepreneurial outcomes is explained...... by factors that siblings share (i.e., family background and neighborhood effects). The average is 28 percent. Hence, entrepreneurship is far less than fully determined at a young age. Our estimates increase only a little when allowing for differential treatment within families by gender and birth order. We...... then investigate a comprehensive set of mechanisms that explain sibling similarities. Parental entrepreneurship plays a large role in explaining sibling similarities, as do shared genes. We show that neighborhood effects matter, but are rather small, particularly when compared with the overall importance of family...

  9. Double impact: what sibling data can tell us about the long-term negative effects of parental divorce.

    Science.gov (United States)

    Wolfinger, Nicholas H; Kowaleski-Jones, Lori; Smith, Ken R

    2003-01-01

    Most prior research on the adverse consequences of parental divorce has analyzed only one child per family. As a result, it is not known whether the same divorce affects siblings differently. We address this issue by analyzing paired sibling data from the 1994 General Social Survey (GSS) and 1994 Survey of American Families (SAF). Both seemingly unrelated regressions and random effects models are used to study the effect of family background on offspring's educational attainment and marital stability. Parental divorce adversely affects the educational attainment and the probability of divorce of both children within a sibship; in other words, siblings tend to experience the same divorce the same way. However, family structure of origin only accounts for a trivial portion of the shared variance in offspring's educational attainment and marital stability, so parental divorce is only one of many factors determining how offspring fare. These findings were unchanged when controlling for a number of differences both between and within sibships. Also, the negative effects of parental divorce largely do not vary according to respondent characteristics.

    2017-12-01

    Full Text Available Siblings of individuals diagnosed with schizophrenia are an important source of family caregiving. Unfortunately, limited information is available about sibling caregivers because existing studies have focused on other family relationships such as parents, spouses, and children. To fill the knowledge gap, the purpose of this study is to describe Korean sibling caregivers’ experience with individuals diagnosed with schizophrenia. Guided by Colaizzi’s descriptive phenomenological methodology, we conducted in-depth, semi-structured, face-to-face interviews with eight individuals who have a sibling (1 diagnosed with schizophrenia and (2 hospitalized in an inpatient psychiatric unit. We discerned six key themes: sorrow, burnout, shame, different perspectives in life, acceptance, and responsibility. We categorized these themes into three groups: suffering, hope, and responsibility and obligation. Sibling caregivers of individuals with schizophrenia experience a mixture of several emotions. Participants loved their brother or sister with schizophrenia, but at the same time they felt shame and fear. While they were burdened by the responsibilities of caregiving, they remained loyal to their sibling with schizophrenia, continuing to help their siblings reach their full potential. Although participants were confused about the symptoms of schizophrenia, they were committed to learning more about the illness. Because we conducted the current study in Korea, the findings of this study may be unique to Korea culture. Further studies are needed to compare and contrast nuanced differences in sibling caregivers’ experience among different cultural groups.

    Full Text Available Progeria, also known as Hutchinson-Gilford syndrome, is an extremely rare, severe genetic condition wherein symptoms resembling aspects of aging are manifested at an early age. It is an autosomal dominant disorder. It is not seen in siblings of affected children although there are very few case reports of progeria affecting more than one child in a family. Here we are presenting two siblings, a 14-year-old male and a 13-year-old female with features of progeria, suggesting a possible autosomal recessive inheritance.

    To asses self-reported quality of life (QoL) and perception of impact of illness on siblings of children with cystic fibrosis (CF). The Child Health Questionnaire was used to assess QoL. The Sibling Perception Questionnaire was used to assess impact of illness. Siblings of children with CF (n= 39) rated their QoL higher than siblings of healthy children on most QoL domains (e.g. Physical Functioning, Behavior, Mental Health). Siblings older than the child with CF reported a higher impact of CF than younger siblings. Perceived impact of illness was higher when the child with CF had been hospitalized or was intermittent or chronically infected with Pseudomonas aeruginosa. Siblings of children with CF reported a good QoL. QoL and impact of illness were related to indices of CF severity. Insight into sibling-issues helps CF teams to provide family-oriented care. © 2010 Blackwell Publishing Ltd.

    A case of half sibling was determined with multiple genetic markers, which could be potentially applied for determination of half sibling relationship from same father. Half sibling relationship was detected by 39 autosomal STR genetic markers, 23 Y-chromosomal STR genetic markers and 12 X -chromosomal STR genetic markers among ZHAO -1, ZHAO -2, ZHAO -3, ZHAO -4, and ZHAO-5. According to autosomal STR, Y-STR and X-STR genotyping results, it was determined that ZHAO-4 (alleged half sibling) was unrelated with ZHAO-1 and ZHAO-2; however, ZHAO-3 (alleged half sibling), ZHAO-5 (alleged half sibling) shared same genetic profile with ZHAO-1, and ZHAO-2 from same father. It is reliable to use multiple genetic markers and family gene reconstruction to determine half sibling relationship from same father, but it is difficult to determination by calculating half sibling index with ITO and discriminant functions.

    2014-01-01

    Although there is an increasing interest in siblings' experiences of loss and grief there is limited knowledge of adolescent's own perspectives, especially in a unique situation as after stillbirth in a reconstituted family. The authors interviewed 13 bereaved adolescents. They were sad that their family was not the same and expressed feelings of being inside family grief, yet outside, because they did not have full access in their reconstituted family. An implication of present findings is that it is important to include all the members of the family in the grieving process, even half-siblings of the deceased child.

    2014-09-01

    Full Text Available In the present paper published data and new analyses are presented and discussed in order to demonstrate the power of family data (siblings and parents to military conscripts with IQ data in the study of the Flynn effect (FE. In particular, it is shown how studies of the mean intelligence changes in sibships of different sizes and changing proportions of sibship sizes can enhance our understanding how these factors may influence FE. Some new analyses of correlations between intelligence and sibship sizes illustrate how family data can be used to investigate changes in the correlation pattern across generations. It is shown that comparison of the secular trends in the general population and in sibling pairs can be a powerful method in the exploration of the relative influence of between-families and within-families factors in the FE. Surprising connections between the birth order effect on intelligence and the FE are demonstrated.

    We examined profiles of sibling relationship qualities in 246 Mexican-origin families living in the United States using latent profile analyses. Three profiles were identified: Positive, Negative and Affect-Intense. Links between profiles and youths’ familism values and adjustment were assessed using longitudinal data. Siblings in the Positive profile reported the highest familism values, followed by siblings in the Affect-Intense profile and, finally, siblings in the Negative profile. Older siblings in the Positive and Affect-Intense profiles reported fewer depressive symptoms than siblings in the Negative profile. Further, in the Positive and Negative profiles, older siblings reported less involvement in risky behaviors than younger siblings. In the Negative profile, younger siblings reported greater sexual risk behaviors in late adolescence than older siblings; siblings in opposite-sex dyads, as compared to same-sex dyads, engaged in riskier sexual behaviors. Our findings highlight sibling relationship quality as promotive and risky, depending on sibling characteristics and adjustment outcomes. PMID:28239217

    The longitudinal associations of older sibling substance use as well as dyadic sibling conflict and collusion to younger sibling substance use were examined in a community-based sample of 244 same-sex sibling pairs. Indirect effects of older siblings on younger sibling substance use were hypothesized via younger sibling deviant peer affiliation and conflict with friends. Adolescents, parents, friends, and teachers completed measures of substance use, conflict, and deviant peer involvement. Observational data were used for both measures of collusion and conflict. Findings suggest that older sibling substance use has a direct effect on younger sibling use, but relationship dynamics and reinforcement played a significant role as well. Specifically, collusion and conflict in the sibling relationship both had indirect effects through younger siblings' deviant peer affiliation. Findings validate the powerful socializing role of both siblings and peers, and elucidate the complex mechanisms through which socialization occurs. Furthermore, data underscore the importance of considering how multiple dimensions of socialization operate in the elaboration of antisocial behavior.

    Siblings of children with vesicoureteral reflux (VUR) are at elevated risk of VUR. Screening siblings may identify VUR before a clinical illness such as a urinary tract infection (UTI), but the benefit of screening has not been demonstrated. We sought to determine the incidence of UTI among siblings, and we hypothesized that the sibling UTI rate is similar between screened and unscreened siblings. We performed a retrospective cohort analysis using insurance claims data (January 1, 2000, to December 31, 2009). Within each family, we identified the index VUR patient and siblings; we included siblings who were enrolled in the insurance plan from birth for at least 1 year. We identified siblings who were screened for VUR and/or had UTI. We investigated the association of screening and UTI, controlling for patient characteristics and clustering within families. Among 617 siblings (associated with 497 index patients), 317 (51%) were girls. Median insurance enrollment time was 53.0 months, with 424 enrolled ≥3 years. Among those with 1 or 3 years of enrollment, the proportions of siblings who experienced UTI was 8.4% (52 of 617) and 10.4% (44 of 424), respectively. Median age at initial UTI was 32.7 months. A total of 223 siblings (36.0%) underwent sibling screening. There was no significant difference in UTI between screened and unscreened siblings (odds ratio 1.57, 95% confidence interval 0.87-2.85; P = .14). In multivariate analysis, screening was not associated with sibling UTI incidence (odds ratio 1.33, 95% confidence interval 0.68-2.60; P = .40). Although UTI is relatively common among siblings of VUR patients, there was no statistically significant difference in UTI incidence between screened and unscreened siblings.

    Stuttering impacts on the child in a variety of ways, notably in terms of communicative impairment and psychosocial impact. In addition, the stuttering disorder has a holistic impact, affecting those with whom the child who stutters lives. Within the family constellation, the closest person to the individual who stutters is often their sibling. This study investigated the experiences of fluent siblings of children who stutter to examine the impact that stuttering may have on their lives. A mixed methods research design incorporated qualitative semi-structured interviews and quantitative questionnaires. The results of the qualitative investigation revealed four aspects of children's lives that were affected by having a sibling who stuttered: the relationship between siblings, the impact on the fluent sibling, the impact on the parent relationship with both children, and the impact on the sibling's relationship with others. Findings revealed that siblings of children who stutter exhibited strongly negative emotions, and differing levels of responsibility associated with their involvement in the actual stuttering management programme. Furthermore, for the fluent sibling, secondary to having a brother or sister who stuttered, communication with and attention from their parents was variable. The results of the quantitative component of the study revealed children who stutter and their siblings demonstrated significantly greater closeness, and concurrently, increased conflict and status disparity than did the control fluent sibling dyads. The parents of the experimental sibling dyads also demonstrated significantly greater partiality towards a child, namely the child who stuttered, than did the parents of the control sibling dyads. The reader will be able to: (1) identify the themes associated with having a sibling who stutters; (2) identify how the quality of the sibling relationship differs between sibling dyads that do and do not consist of a sibling who stutters; and

    In this study, we demonstrate the complexities of performing a sibling analysis with a re-examination of associations between cell phone exposures and behavioral problems observed previously in the Danish National Birth Cohort. Children (52,680; including 5441 siblings) followed up to age 7 were included. We examined differences in exposures and behavioral problems between siblings and non-siblings and by birth order and birth year. We estimated associations between cell phone exposures and behavioral problems while accounting for the random family effect among siblings. The association of behavioral problems with both prenatal and postnatal exposure differed between siblings (odds ratio (OR): 1.07; 95% confidence interval (CI): 0.69-1.66) and non-siblings (OR: 1.54; 95% CI: 1.36-1.74) and within siblings by birth order; the association was strongest for first-born siblings (OR: 1.72; 95% CI: 0.86-3.42) and negative for later-born siblings (OR: 0.63; 95% CI: 0.31-1.25), which may be because of increases in cell phone use with later birth year. Sibling analysis can be a powerful tool for (partially) accounting for confounding by invariant unmeasured within-family factors, but it cannot account for uncontrolled confounding by varying family-level factors, such as those that vary with time and birth order.

    Children with a physical disability, psychological disorder, or of nonnormative weight are often targets of peer victimization. Sibling victimization, however, is more common than peer victimization, but rarely explored. We investigated linkages between sibling victimization and whether children had a physical disability, psychological disorder (i.e., internalizing disorder, attention deficit disorder/attention-deficit hyperactivity disorder), and were perceived by parents as being thinner than average or overweight. Also, we explored how the extent and kinds of sibling victimization experiences were related to these characteristics in childhood. A US probability sample of adult caregivers of a child aged 0 to 9 (N = 780; 50% women; mean age 4.58) in 2-child households who completed a telephone interview. Controlling for other forms of maltreatment and individual and family characteristics, children with a physical disability and parent-perceived children who are thinner than average and children who are overweight experienced more sibling victimization. Children with an internalizing disorder experienced less sibling victimization. Sibling victimization did not differ for children with and without ADHD. Children perceived to be overweight by parents and children with a physical disability were at increased risk of experiencing more types of sibling victimization. Children with a physical disability had greater odds of being victims of property victimization by a sibling. Children with a physical disability or perceived as different from average weight are at risk for sibling victimization. Using a nationally representative sample, this is the first study to highlight the importance of screening for sibling victimization in families of children with a disability and/or nonnormative weight status.

    It is believed that the main advantage of affected sib-pair tests is that their application requires no information about the underlying genetic mechanism of the disease. However, here it is proved that the mean test, which can be considered the most prominent of the affected sib-pair tests, is equivalent to lod score analysis for an assumed recessive mode of inheritance, irrespective of the true mode of the disease. Further relationships of certain sib-pair tests and lod score analysis under specific assumed genetic modes are investigated.

    This study, the first in Zambia using the Strange Situation Procedure (SSP) to observe attachment relationships and the "very first" observational study of infant-sibling attachment, examined patterns of infant-mother and infant-sibling attachment, and tested their association. We included siblings who were substantially involved in caregiving activities with their younger siblings. We hypothesized that infants would develop attachment relationships to both mothers and siblings; the majority of infants would be classified as securely attached to both caregivers, and infant-mother and infant-sibling attachment would be unrelated. The sample included 88 low-income families in Lusaka, Zambia (average of 3.5 children; SD = 1.5). The SSP distributions (infant-mother) were 59% secure, 24% avoidant and 17% resistant, and 46% secure, 20% avoidant, 5% resistant and 29% disorganized for three- and four-way classifications, respectively. The infant-sibling classifications were 42% secure, 23% avoidant and 35% resistant, and 35% secure, 23% avoidant, 9% resistant and 33% disorganized for three- and four-way classifications, respectively. Infant-mother and infant-sibling attachment relationships were not associated.

    Research has demonstrated that siblings of chronically ill children can experience significant emotional and behavior changes; however, few studies have looked at the specific impact of pediatric hospitalization on the nonhospitalized child. Studies also indicate that children who receive age-appropriate information are better equipped to handle the stress and anxiety often associated with hospitalization.This study explored whether siblings of hospitalized children who received educational interventions had lower anxiety levels compared to siblings who did not receive interventions. A pretest-posttest experimental design was used with 50 subjects, ages 6-17 years, recruited from a children's hospital within a university medical center. Subjects were matched according to age, sex, and race, with 25 siblings each in the experimental and control groups. Siblings assigned to the experimental group received interventions from a standardized educational intervention protocol developed by the researcher. Interventions focused on teaching the sibling about hospitalization, illness or injury, and treatment for the patient, based on cognitive stages of development. All interventions were conducted by child life specialists on staff at the hospital with extensive training and experience in preparation and procedural teaching. Results shows that siblings who received educational interventions had significantly lower anxiety levels after interventions, compared to siblings who did not receive interventions. These findings have significant impact on children's health care and supporting family needs when a child is hospitalized.

    Homologous chromosome pairing and synapsis are prerequisitefor accurate chromosome segregation during meiosis. Here, we show that afamily of four related C2H2 zinc-finger proteins plays a central role inthese events in C. elegans. These proteins are encoded within a tandemgene cluster. In addition to the X-specific HIM-8 protein, threeadditional paralogs collectively mediate the behavior of the fiveautosomes. Each chromosome relies on a specific member of the family topair and synapse with its homolog. These "ZIM" proteins concentrate atspecial regions called meiotic pairing centers on the correspondingchromosomes. These sites are dispersed along the nuclear envelope duringearly meiotic prophase, suggesting a role analogous to thetelomere-mediated meiotic bouquet in other organisms. To gain insightinto the evolution of these components, wecharacterized homologs in C.briggsae and C. remanei, which revealed changes in copy number of thisgene family within the nematode lineage.

    Purpose A growing body of research indicates that siblings uniquely influence each other’s health risk behaviors during adolescence and young adulthood. Mechanisms underlying these associations, however, are largely unknown because they are rarely tested directly. The present study addressed this gap by examining the role of sibling modeling in explaining changes in Mexican-origin youths’ deviant and sexual risk behaviors over time. Methods The sample included 380 Mexican-origin siblings (older sibling age: M = 21.18, SD = 1.59; younger sibling age: M = 18.19, SD = .46) from (N = 190) families. Participants provided self-reports of their sibling relationship qualities, including modeling, as well as their engagement in deviant and sexual risk taking behaviors in two home interviews across a two-year span. Results A series of residualized regression models revealed that younger siblings’ perceptions of modeling moderated the links between older siblings’ deviant and sexual risk behaviors and younger siblings’ subsequent behaviors in those same domains. Specifically, high levels of modeling predicted stronger associations between older siblings’ earlier and younger siblings’ later risk behaviors controlling for younger siblings’ earlier behaviors as well as variables that have been used as proxies for social learning in previous research. Conclusions Social learning mechanisms, especially modeling, are salient processes through which older siblings transmit norms and expectations regarding participation in health risk behaviors. Future research should continue to explore the ways in which siblings influence each other because such processes are emerging targets for intervention and prevention. PMID:24287013

  12. Siblings' personality traits and types of sibling relationship in childhood

    Full Text Available The contribution presents a follow-up study of sibling relationship and personality in 87 sibling dyads in early/middle childhood from parental perspective. At Time 1 all siblings attended pre-school and one year later approximately half of the older siblings entered compulsory school. At both times of measurement siblings' mothers and fathers independently reported on their children's personality characteristics using the Inventory of Child Individual Differences (Halverson et al., 2003; Slovene adaptation, Zupančič & Kavčič, 2009 and on the observed sibling warmth, agonism, and rivalry using the Parental Expectations and Perceptions of Children's Sibling Relationships Questionnaire (Kramer, 2001. The predictive relationship obtained by two sets of cross-rater analyses (between maternal ratings of child personality and paternal reports on sibling relationship, and vice versa suggested that (a personality traits of both siblings and (b the match between siblings' personalities are associated with sibling type (affectionate, involved or average membership. Among personality traits, disagreeableness seems to be an especially significant contributor to sibling relationship quality.

  13. Sibling eating behaviours and differential child feeding practices reported by parents.

    2009-04-01

    The purpose of this study was to investigate the intra-familial relationships between parental reports of feeding practices used with siblings in the same family, and to evaluate whether differences in feeding practices are related to differences in siblings' eating behaviours. Eighty parents of two sibling children completed measures assessing their feeding practices and child eating behaviours. Parents reported using greater restrictive feeding practices with children who were fussier and desired to drink more than their sibling. Parents reported using more pressure to eat with siblings who were slower to eat, were fussier, emotionally under-ate, enjoyed food less, were less responsive to food, and were more responsive to internal satiety cues. Restriction and pressure to eat appear to be part of the non-shared environment which sibling children experience differently. These feeding practices may be used differently for children in the same family in response to child eating behaviours or other specific characteristics.

    We determined the correlation between sibling refractive errors adjusted for shared and unique environmental factors using data from the Collaborative Longitudinal Evaluation of Ethnicity and Refractive Error (CLEERE) Study. Refractive error from subjects' last study visits was used to estimate the intraclass correlation coefficient (ICC) between siblings. The correlation models used environmental factors (diopter-hours and outdoor/sports activity) assessed annually from parents by survey to adjust for shared and unique environmental exposures when estimating the heritability of refractive error (2*ICC). Data from 700 families contributed to the between-sibling correlation for spherical equivalent refractive error. The mean age of the children at the last visit was 13.3 ± 0.90 years. Siblings engaged in similar amounts of near and outdoor activities (correlations ranged from 0.40-0.76). The ICC for spherical equivalent, controlling for age, sex, ethnicity, and site was 0.367 (95% confidence interval [CI] = 0.304, 0.420), with an estimated heritability of no more than 0.733. After controlling for these variables, and near and outdoor/sports activities, the resulting ICC was 0.364 (95% CI = 0.304, 0.420; estimated heritability no more than 0.728, 95% CI = 0.608, 0.850). The ICCs did not differ significantly between male-female and single sex pairs. Adjusting for shared family and unique, child-specific environmental factors only reduced the estimate of refractive error correlation between siblings by 0.5%. Consistent with a lack of association between myopia progression and either near work or outdoor/sports activity, substantial common environmental exposures had little effect on this correlation. Genetic effects appear to have the major role in determining the similarity of refractive error between siblings. Copyright 2014 The Association for Research in Vision and Ophthalmology, Inc.

    Limited research has examined the impact of a child's death from cancer on siblings. Even less is known about how these siblings change over time. This study compared changes in siblings 1 (T1) and 2 (T2) years after the death of a brother or sister from cancer based on bereaved parent and sibling interviews. Participants across 3 institutions represented 27 families and included bereaved mothers (n = 21), fathers (n = 15), and siblings (n = 26) ranging from 8 to 17 years old. Participants completed semistructured interviews. Content analysis identified emerging themes and included frequency counts of participant responses. McNemar tests examined differences in the frequency of responses between T1 and T2 data. Participants reported similar types of changes in bereaved siblings at both time points, including changes in sibling relationships, life perspectives, their personal lives, and school performance. A new theme of "openness" emerged at T2. Frequencies of responses differed according to mother, father, or sibling informant. Overall, participants less frequently reported changes at T2 versus T1. Compared with findings in the first year, participants reported greater sibling maturity at follow-up. Overall changes in bereaved siblings continued over 2 years with less frequency over time, with the exception of increases in maturity and openness. Providers can educate parents regarding the impact of death of a brother or sister over time. Nurses can foster open communication in surviving grieving siblings and parents as potential protective factors in families going through their grief.

    Research on family factors in paediatric pain has primarily focused on parents; the role of siblings has been largely ignored. This study examined whether sibling relationship quality was related to siblings' behaviours during experimental pain, and whether the behaviours of an observing sibling were related to children's pain outcomes. Ninety-two sibling dyads between 8-12 years old completed both observational and questionnaire measures of sibling relationship quality. Children took turns completing the cold pressor task (CPT) in a counterbalanced order with their sibling present. Pain outcomes (intensity, fear, tolerance) were recorded for each sibling, and the behaviour of the observing and participating siblings during the CPT were coded as attending, non-attending, and coping/encouragement. Structural equation modelling, using the actor-partner interdependence model, was conducted to analyse the dyadic data. While participating in the CPT with their sibling present, greater levels of warmth and positivity in the sibling relationship were related to children engaging in more non-attending behaviours and less attending behaviours. Greater levels of attending behaviours by the observing child was related to the sibling having a lower pain tolerance, and greater levels of coping/encouragement behaviours by the observing child was related to the sibling reporting greater pain intensity and fear during the CPT. Children with warmer/positive sibling relationships were more likely to respond to acute pain by shifting the focus away from their pain experience (e.g., through distraction) when a sibling was present. Pain-focused behaviours by an observing sibling are related to greater child pain and fear during experimental pain.

    When there is a child with cancer in the family, the entire family is affected. Childhood cancer is a highly stressful experience that affects the adaptation of family member to psychosocial tasks. Many of the family stresses and changes that accompany childhood cancer have a severe impact on siblings. An understanding of the experiences and needs of such siblings is vital. The aim of this study was to understand the nature of the overall experiences of a child who has a brother or sister with cancer. Searches of CINAHL, MEDLINE/PubMed, Science Direct, Scopus, Eric, and Chinese electronic periodical services identified 10 qualitative studies that were published between 1960 and 2013. An appraisal of the primary studies was carried out using the Joanna Briggs Institute Qualitative Assessment and Review Instrument. Siblings of children with cancer were found to have experienced 4 themes: (1) the disintegration of life, (2) marginalization within their family relationships, (3) self-transcendence during the normalization of family relationships, and (4) maintenance of family integrity and family normality. Siblings of children with cancer experience a great deal of chaos in their family life, and this affects their self-esteem and family intimacy. Being with the sick child may help siblings understand the sick child's suffering and experiences. The findings of this review provide evidence to help health professionals to assess the needs of the siblings to enhance their sense of self within the family. Providing the siblings with suitable resources should result in better adjustment.

    The goals of this study were to examine longitudinal changes in perceived control in adolescents' sibling relationships and to describe the nature and correlates of three distinct control patterns: Firstborn dominant, equal, and secondborn dominant. Firstborn and secondborn adolescents in 184 predominately European-American families participated in home interviews and a series of phone interviews as part of a longitudinal a study of family relationships and adolescent development. Findings revealed changes in control over three years as well as sibling differences. In addition, different patterns of control were linked to qualities of the sibling relationship and to adolescent adjustment. The different roles that firstborn and secondborn siblings assume, and why these roles are linked to relationship experiences and adjustment, are discussed.

    Full Text Available Abstract Background Genomic sequencing of SNPs is increasingly prevalent, though the amount of familial information these data contain has not been quantified. Methods We provide a framework for measuring the risk to siblings of a patient's SNP genotype disclosure, and demonstrate that sibling SNP genotypes can be inferred with substantial accuracy. Results Extending this inference technique, we determine that a very low number of matches at commonly varying SNPs is sufficient to confirm sib-ship, demonstrating that published sequence data can reliably be used to derive sibling identities. Using HapMap trio data, at SNPs where one child is homozygotic major, with a minor allele frequency ≤ 0.20, (N = 452684, 65.1% we achieve 91.9% inference accuracy for sibling genotypes. Conclusion These findings demonstrate that substantial discrimination and privacy risks arise from use of inferred familial genomic data.

    Findings about the psychological adjustment of siblings of children with autism spectrum disorder have been inconsistent in western literature and little is known among non-western societies. This study explored the psychological adjustment of siblings of children with autism spectrum disorder in Hong Kong. A total of 116 families with siblings of children with autism spectrum disorders co-morbid with learning disability were included in the study. Parents completed questionnaires about sibling emotional and behavioural adjustment, and their own mental well-being, quality of life, and family functioning. Siblings completed a questionnaire on their relationship with the autistic proband. Parent ratings did not reveal any significant negative impact on the emotional and behavioural adjustment of the typically developing siblings of children with autism spectrum disorder, but there were concerns about their peer relationships and weak prosocial behaviours. When cut-off scores were used to screen for risk of mental health problems, a quarter of the siblings warranted further assessment. Parents' quality of life and family functioning were significant predictors of sibling adjustment. In managing children with autism spectrum disorder, it is necessary to bear in mind the adjustment of their siblings, especially their peer relationships and prosocial behaviour. Adopting a holistic approach to address the psychosocial needs of the parents can facilitate sibling adjustment.

    This study examined associations between changes in sibling relationships and changes in parental differential treatment and corresponding changes in children's adjustment. One hundred thirty-three families were assessed at 3 time points. Parents rated children's externalizing problems, and children reported on sibling relationship quality, parental differential treatment, and depressive symptoms. On average, older siblings were 10, 12, and 16 years old, and younger siblings were 8, 10, and 14 years old at Waves 1, 2, and 3, respectively. Results from hierarchical linear modeling indicated that as sibling relationships improved over time, children's depressive symptoms decreased over time. In addition, as children were less favored over their siblings over time, children's externalizing problems increased over time. Findings highlight the developmental interplay between the sibling context and children's adjustment. Copyright 2006 APA, all rights reserved).

    Guided by an ecological framework, we explore how siblings' and parents' roles, relationships, and activities are intertwined in everyday life, providing unique and combined contributions to development. In a departure from past research that emphasized the separate contributions of siblings and parents to individual development, we find that examining the conjoint or interactive effects of sibling and parent influences promises to extend our understanding of the role of family in children's and adolescents' social, emotional, and cognitive development. Understood within the context of family and sociocultural characteristics, siblings' unique roles as agents of socialization are illuminated.

    Though it is known that different familial relationships influence one another (e.g., Yu & Gamble, 2008) the influence of outside relationships (i.e., peers) on family dynamics (i.e., sibling relationships) is less clear. Thus, the authors examined the association differential peer experiences had on the conflict frequency, conflict intensity, and relationship quality of the sibling relationship. A 1-year longitudinal design measured first-born siblings in Grades 8, 10, and 12 along with their second-born siblings. In the first year, participants were brought to the university to complete questionnaires and in the following year, siblings again participated by completing online questionnaires at home. Results partially confirmed the study hypotheses that adolescents would show greater sibling conflict and poorer relationship quality with greater peer group differences, revealing that when peer group differences between siblings were greater, the youngest siblings reported more intense sibling conflicts (pe = -.10 p siblings reported greater relationship positivity (pe = .13 p siblings' differential experiences beyond familial influence to focus on outside sources to better understand developmental fluctuations in siblings' relationships.

    Many people with severe mental illness (SMI) have siblings. Siblings are often both natural agents to promote service users' recovery and vulnerable to mental ill health due to the negative impact of psychosis within the family. Despite a wealth of research evidence supporting the effectiveness of psychoeducation for service users with SMI and their family members, in reducing relapse and promoting compliance with treatment, siblings remain relatively invisible in clinical service settings as well as in research studies. If psychoeducational interventions target siblings and improve siblings' knowledge, coping with caring and overall wellbeing, they could potentially provide a cost-effective option for supporting siblings with resulting benefits for service users' outcomes. To assess the effectiveness of psychoeducation compared with usual care or any other intervention in promoting wellbeing and reducing distress of siblings of people affected by SMI.The secondary objective was, if possible, to determine which type of psychoeducation is most effective. We searched the Cochrane Schizophrenia Group Trials Register and screened the reference lists of relevant reports and reviews (12th November 2013). We contacted trial authors for unpublished and specific data on siblings' outcomes. All relevant randomised controlled trials focusing on psychoeducational interventions targeting siblings of all ages (on their own or amongst other family members including service users) of individuals with SMI, using any means and formats of delivery, i.e. individual (family), groups, computer-based. Two review authors independently screened the abstracts and extracted data and two other authors independently checked the screening and extraction process. We contacted authors of trials to ascertain siblings' participation in the trials and seek sibling-specific data in those studies where siblings' data were grouped together with other participants' (most commonly other family members

    A child's disability or acute or chronic illness has an effect on all family members, including siblings of the affected child. Children's books, fiction and non-fiction, can be used to support siblings by providing information, addressing feelings, offering insight, assuring the child that others have had similar problems, and facilitating coping. Nurses can introduce children and their families to useful books by having books or book covers on display that the child can choose from; providing families with lists of books; and/or assessing the child's needs, interests and reading level, and recommending a specific title.

    2011-10-01

    This paper provides a review of the literature related to adult siblings of learning-disabled people. Siblings of learning-disabled people are often looked upon as next of kin when older parents die; however, there is little research regarding sibling views and wishes. A literature review of published peer-reviewed empirical research was undertaken. Electronic databases and citation tracking were used to collate data using key terms such as adult siblings and learning disability. Relevant articles were analysed, compared and contrasted. Six key themes emerged suggesting a varied impact of learning disability upon sibling lives in areas that include life choices, relationships, identity and future plans. Some siblings report a positive impact upon life, others state their lives are comparable with other adults who do not have a learning-disabled sibling and others still report a negative impact. Sibling roles and relationships are varied. Evidence suggests that sibling roles, relationships and experience are affected by life stage. Parents often have a primary care role for the disabled person, whilst siblings perform a more distant role; however, sibling involvement often rises when parents are no longer able to provide previous levels of support. Many factors appear to affect the sibling experience and uptake of roles including gender, life stage and circumstances, level of disability, health status and relationships between family members. Siblings are concerned about the future, particularly when parents are no longer able to provide support, and many appear to have expectations of future responsibilities regarding their disabled sibling. As siblings of people who have a learning disability are often expected by society to provide support, it is important that health and social care practitioners are aware of issues that may impact on this relationship. © 2011 Blackwell Publishing Ltd.

    Siblings of persons with mental illness who assume primary caregiving roles experience substantial and tangible economic impacts associated with this responsibility. This study investigated mailed survey responses collected from 156 adult siblings of persons with mental illness from New York State to examine instrumental costs associated with providing support to siblings with illness. Genders of both siblings, severity of the relatives' mental illness, and number of surviving parents in the family distinguished those occupying primary caregiving responsibility from those not in primary roles. Current caregivers incurred greater instrumental costs in the form of financial expenses, time spent in care activities, and crisis involvement than did those who were not primary care providers. Additional demographic and behavioral factors related to siblings with and without illness were associated with specific dimensions of instrumental expenditure. As siblings become increasingly engaged in caregiving, social service professionals must assume leadership in promoting programs and policies that meaningfully support family involvement for relatives with mental illness.

  17. Harnessing the power of sibling relationships as a tool for optimizing social-emotional development.

    Sibling relationships provide one of the most stable and powerful developmental contexts for the transmission of both prosocial and antisocial behavior. As a source of support and skill development, sibling relationships can build competence in self-regulation and emotional understanding. However, sibling relationships marked by antisocial behavior, substance use, and conflict place children at risk for a host of negative outcomes. Family relationship features, particularly parenting practices and discord, contribute strongly to both the quality of sibling relationships and children's well-being. Our review of intervention strategies reveals that the potential of sibling relationships to promote socioemotional development may be best realized through family-centered approaches that build prosocial sibling interactions, curtail child behavior problems, and strengthen parenting.

  18. Sibling Competition & Growth Tradeoffs. Biological vs. Statistical Significance.

    Early childhood growth has many downstream effects on future health and reproduction and is an important measure of offspring quality. While a tradeoff between family size and child growth outcomes is theoretically predicted in high-fertility societies, empirical evidence is mixed. This is often attributed to phenotypic variation in parental condition. However, inconsistent study results may also arise because family size confounds the potentially differential effects that older and younger siblings can have on young children's growth. Additionally, inconsistent results might reflect that the biological significance associated with different growth trajectories is poorly understood. This paper addresses these concerns by tracking children's monthly gains in height and weight from weaning to age five in a high fertility Maya community. We predict that: 1) as an aggregate measure family size will not have a major impact on child growth during the post weaning period; 2) competition from young siblings will negatively impact child growth during the post weaning period; 3) however because of their economic value, older siblings will have a negligible effect on young children's growth. Accounting for parental condition, we use linear mixed models to evaluate the effects that family size, younger and older siblings have on children's growth. Congruent with our expectations, it is younger siblings who have the most detrimental effect on children's growth. While we find statistical evidence of a quantity/quality tradeoff effect, the biological significance of these results is negligible in early childhood. Our findings help to resolve why quantity/quality studies have had inconsistent results by showing that sibling competition varies with sibling age composition, not just family size, and that biological significance is distinct from statistical significance.

    Siblings of children with chronic illness have unique experiences that can affect their school functioning, such that they may miss ongoing periods of school, experience difficulties with schoolwork or experience changes in their peer and teacher interactions. This review provides an overview of these siblings' school experiences. Six databases (Medline, PsychINFO, CINAHL, ERIC, Embase and The Cochrane Library) were systematically searched for studies examining the school experiences and peer relationships of siblings of children with chronic illness, as well as school-based interventions for these siblings. Studies were included if they were published in or after 2000 and were published in English. We identified 2137 articles upon initial search. From these, we identified 28 eligible studies examining the school experiences of >1470 siblings of children with chronic illness. Three key themes were identified throughout the reviewed articles. The literature described 1) the psychological impact on siblings at school; 2) decreases in school attendance and academic functioning, and; 3) changes or perceived differences in peer and teacher interactions. Siblings value teacher and peer support, and this support may contribute to better sibling school functioning. Many siblings are socially resilient, yet overlooked, members of the family who may present with psychological, academic and peer related difficulties at school following diagnosis of a brother or sister with chronic illness. Future research is needed to further delineate the sibling school experience to better facilitate the development of targeted sibling support interventions within the school environment.

    Sibling unity during family transitions is considered a protective factor for child behavior problems, but there is little empirical support for the widespread child protection policy of placing siblings together in foster care. In a prospective study of 156 maltreated children, siblings were classified in 1 of 3 placement groups: continuously together (n = 110), continuously apart (n = 22), and disrupted placement (siblings placed together were separated; n = 24). Changes in child adjustment as a function of sibling relationship and placement group were examined. Sibling positivity predicted lower child problems at follow-up (about 14 months later), while sibling negativity predicted higher child problems. Placement group did not affect child behavior problems at follow-up; however, compared to siblings in continuous placement (either together or apart), siblings in disrupted placement with high initial behavior problems were rated as having fewer problems at follow-up, while siblings in disrupted placement with low initial behavior problems were rated as having more problems at follow-up. These findings highlight the importance of considering relationships between siblings and the risk that one poses to another before early placement decisions are made.

    Chronic illness of a child puts healthy children of the family at risk of distress. Previous studies have demonstrated that healthy children's psychological symptoms can be reduced when the child knows more about the disease. So far, there is limited evidence of the effectiveness of psychoeducational interventions for healthy children. To compare the effectiveness of an inpatient family-oriented rehabilitation program with vs without additional psychoeducational sessions for healthy children of families with children with cancer. We performed a controlled study in 4 German family-oriented rehabilitation clinics. The outcomes of n = 73 healthy children (mean age: M = 9.55; SD = 3.14; range: 4-18), who participated in 5 additional psychoeducational sessions, were compared with the outcomes of n = 111 healthy children (mean age: M = 8.85; SD = 3.28; range: 4-17), who underwent the usual inpatient rehabilitation program. Primary outcomes were the healthy children's cancer-specific knowledge and their emotional symptoms. Secondary outcomes were family satisfaction and quality of life. Intention-to-treat analyses showed that both groups improved significantly from preintervention to postintervention. Improvements comprised knowledge about cancer (F(1,174) = 11.03, p child with cancer. Additional psycho-educational sessions did not show any substantial additional improvement.

    2008-06-01

    The growth of early intervention in psychosis services (EIPS) has prompted needed research to provide a robust evidence base to underpin practice. The typical service model embraces key psychosocial interventions, including family interventions. A literature review revealed a number of relevant studies that recognized the role of siblings in families affected by severe mental illness or mental impairment, but little was found about the impact of first-episode psychosis on siblings. To address this apparent oversight, we conducted a study to gain an understanding of sibling experiences. Ten siblings (ages 16 to 30) with a brother or sister diagnosed with first-episode psychosis took part in individual semi-structured interviews. The key findings were grouped in regard to emotional impact, relationships in the family, and siblings' roles and coping patterns. The study also revealed that families are able to identify positive gains out of a fundamentally negative experience.

    Family therapists understand that children presenting for treatment are often bearers of symptoms signalling relational problems within the family system. Rather than addressing the children's symptoms in isolation, family therapists typically take those relational problems as their starting point in therapy. This study used the School-aged Assessment of Attachment (SAA) to assess the self-protective (attachment) strategies of the siblings of children presenting for psychiatric evaluation and also of the siblings of control children drawn from the normative population. Siblings of children in the clinical group were much more likely than siblings of control children to use at-risk self-protective strategies and to have markers suggestive of unresolved loss or trauma. School-aged siblings were found to use a broad range of strategies, and the pattern of change from first born to later born involved either a reversal of strategy or a shift to a more complex strategy. The study highlights that siblings of children presenting to mental health services are significantly affected by family relational stress. A family systems approach to assessment, one that enquires about the wellbeing of all family members, will ensure that the emotional needs of siblings are also addressed during the therapy process.

    Sibling relationships are usually lifelong and reciprocal. They can assume particular significance when a brother or sister has a learning disability. Until recently, adult siblings of people with disabilities such as severe autism have been ignored by policy, practice and research. This qualitative study contributes to an emerging literature by exploring how adult siblings, who have a brother or sister with autism (plus learning disability) and living in England, give meaning to their family (and caring) relationships and engage with service delivery. We spoke to 21 adult siblings using semi-structured interviews and met with 12 of their siblings with autism. Our analysis, using a broad narrative approach, demonstrates the continuity of the sibling relationship and an enduring personalised commitment. The nature of this relationship, however, is sensitive to context. How non-disabled adult siblings relate to their childhood experience is fundamental when making sense of this, as is their need to fulfil other social and family obligations, alongside their 'sense of duty' to support their disabled brother or sister. Sibling experience was further mediated by negotiating their 'perceived invisibility' in social care policy and practice. Our work concludes that by understanding the way relationships between siblings have developed over time, adult siblings' contribution to the lives of their brother or sister with autism can be better supported for the benefit of both parties. Such an approach would support current policy developments. © 2013 John Wiley & Sons Ltd.

    Siblings can be seen as a huge resource in caring for adults with a diagnosis of schizophrenia: Many expect to take over the caring role of caring when their parents no longer can, and positive sibling relationships are related to better outcomes for adults with a diagnosis of schizophrenia (Smith, Greenberg and Seltzer, 2007).

    A growing body of research documents the significance of siblings and sibling relationships for development, mental health, and behavioral risk across childhood and adolescence. Nonetheless, few well-designed efforts have been undertaken to promote positive and reduce negative youth outcomes by enhancing sibling relationships. Based on a theoretical model of sibling influences, we conducted a randomized trial of Siblings Are Special (SIBS), a group-format afterschool program for fifth graders with a younger sibling in second through fourth grades, which entailed 12 weekly afterschool sessions and three Family Nights. We tested program efficacy with a pre- and post-test design with 174 families randomly assigned to condition. In home visits at both time points, we collected data via parent questionnaires, child interviews, and observer-rated videotaped interactions and teachers rated children's behavior at school. The program enhanced positive sibling relationships, appropriate strategies for parenting siblings, and child self-control, social competence, and academic performance; program exposure was also associated with reduced maternal depression and child internalizing problems. Results were robust across the sample, not qualified by sibling gender, age, family demographics, or baseline risk. No effects were found for sibling conflict, collusion, or child externalizing problems; we will examine follow-up data to determine if short-term impacts lead to reduced negative behaviors over time. The breadth of the SIBS program's impact is consistent with research suggesting that siblings are an important influence on development and adjustment and supports our argument that a sibling focus should be incorporated into youth and family-oriented prevention programs.

    This study investigates whether parental feeding practices are part of the shared environment or responsive to characteristics of different children from the same family. Thirty-six mothers with two children (4-12 y) of which 10 sibling-pairs were discordant for weight status (healthy weight-overweight), were invited to the lab for a standard meal. Maternal responsive and controlling behaviour was observed and coded. Children's weight status and eating behaviour was assessed. Results indicated that in general, mothers show similar levels of responsiveness and controlling behaviour within families. However, the use of mothers' authoritarian and permissive behaviour and her expressions of involvement at mealtime were consequently related to children's amount of food eaten and their restraining eating style. Thus, the amount of food children eat, both observed and assessed by questionnaire, seems related to more maladaptive parenting practices in mothers. This pleads for more tailor-made guidelines when advising parents of children with eating- and weight problems. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Waardenburg syndrome, an autosomal dominant disorder characterized by sensorineural hearing loss, pigmentary disturbances and other developmental defects, is the most frequent form of congenital deafness in humans. Mutations in the PAX3 gene, a transcription factor expressed during embryonic development, is associated with WS types I and III. Here we report the identification of a novel acceptor splice site mutation (86-2 A-->G) in the paired domain of the human PAX3 gene causing WS type I in a three generation family.

    This study used nationwide hospital records to examine sibling risk of any type of anxiety disorder in Sweden over a 40-year period. This study, carried out between 1 January 1968 and 31 December 2007, of the entire population of Sweden, linked information on family relationships from the nationwide Multi-Generation Register with information from the nationwide Swedish Hospital Discharge Register on first diagnosis of anxiety disorder. A total of 42,602 persons hospitalized for anxiety disorders and 2093 affected siblings were identified. Standardized incidence ratios (SIR) were calculated by comparing risk in siblings of persons hospitalized for anxiety disorders with risk in persons whose siblings had no hospital diagnosis of anxiety disorders. The sibling risk was 2.26, which was independent of sex and age differences between siblings. The SIR was highest in siblings sibling diagnosed with any anxiety disorder resulted in increased risks of a number of disorders; the highest increased risk was of social phobia (SIR 3.68, 95% confidence interval, 1.68-7.69). Risk of panic disorder, generalized anxiety disorder, mixed anxiety and depressive disorder, and obsessive-compulsive disorder was raised in female but not male siblings. Heritable effects likely play an important role in the cause of anxiety disorders, but the extent of their role remains to be established. Important contributions could be made by studies of gene-environment interactions that have sufficient sample sizes to produce reliable results. © 2011 The Authors.

    Although socioemotional competencies have been identified as key components of youths’ positive development, most studies on empathy are cross-sectional, and research on the role of the family has focused almost exclusively on parental socialization. This study examined the developmental course of empathy from age 7 to 14 and the within-person associations between sibling warmth and conflict and youths’ empathy. On three occasions across 2 years, mothers, fathers, and the two eldest siblings from 201 White, working- and middle-class families provided questionnaire data. Multilevel models revealed that, controlling for youths’ pubertal status and parental education, girls’ empathy increased during the transition to adolescence and then leveled off, but boys’ lower levels of empathy remained relatively unchanged. Moreover, controlling for parental responsiveness and marital love, at times when firstborns and second-borns reported more sibling warmth and less sibling conflict than usual, they also reported more empathy than usual. The within-person association between sibling warmth and empathy also became stronger over time. Findings highlight gender differences in empathy development and the unique role of siblings in shaping each other’s socioemotional characteristics during adolescence. PMID:22714744

    Siblings of schizophrenia patients are from the patient's perspective important support providers, but most studies on family burden have focused on the parental role. This study aims to develop a detailed analysis of the psychological aspects of having a sibling with schizophrenia. We did a qualitative study with audiotaped semistructured interviews of 16 siblings. The reliability of the inductive categorization of data was high. A unifying theme appeared to be an emotional sibling bond characterized by feelings of love, sorrow, anger, envy, guilt, and shame. The major categories linked to coping with the situation were avoidance, isolation, normalization, caregiving, and grieving. A third major theme consisted of a fear of possible schizophrenia heredity. The siblings described concerns about the impact of a family history of psychiatric illness, a fear of becoming mentally ill, and reflections about "bad genes." Our findings support earlier findings of coping patterns but complement them by providing a model that includes awareness of genetic vulnerability as an important part of siblings' subjective burden.

    The present study is the first to examine patterns in sibling relationship quality and the associations of these patterns with internalizing and externalizing problem behavior, as well as self-perceived competence, in middle childhood. Self-report questionnaires (e.g., Sibling Relationship Questionnaire, Self-Perception Profile for Children, Youth Self Report) were administered among 1,670 Dutch children (Mage = 11.40 years, SD = .83) attending 51 different Dutch schools. Three sibling relationship clusters were found: a conflictual cluster (low on warmth, high on conflict), an affect-intense cluster (above average on warmth and conflict), and a harmonious cluster (high on warmth, low on conflict). Sister pairs were underrepresented in the conflictual cluster and overrepresented in the harmonious cluster. Children with conflictual sibling relationships reported significantly more internalizing and externalizing problems, and lower academic and social competence and global self-worth, than children with harmonious sibling relationships. Children with affect-intense sibling relationships reported less aggression and better social competence than children with conflictual sibling relationships. Our findings indicate that it is fruitful to combine indices of sibling warmth and conflict to examine sibling relationship types. Relationship types differed significantly concerning internalizing and externalizing problems, but also concerning self-perceived competence. These findings extend our knowledge about sibling relationship types and their impact on different aspects of child adjustment. Whereas harmonious sibling relationships are the most beneficial for adjustment, sibling conflict mainly has a negative effect on adjustment in combination with lack of sibling warmth. Implications and future directions are discussed.

  19. 'Adoption' by maternal siblings in wild chimpanzees.

    Directory of Open Access Journals (Sweden)

    Catherine Hobaiter

    Full Text Available The adoption of unrelated orphaned infants is something chimpanzees and humans have in common. Providing parental care has fitness implications for both the adopter and orphan, and cases of adoption have thus been cited as evidence for a shared origin of an altruistic behaviour. We provide new data on adoptions in the free-living Sonso chimpanzee community in Uganda, together with an analysis of published data from other long-term field sites. As a default pattern, we find that orphan chimpanzees do not become adopted by adult group members but wherever possible associate with each other, usually as maternal sibling pairs. This occurs even if both partners are still immature, with older individuals effectively becoming 'child household heads'. Adoption of orphans by unrelated individuals does occur but usually only if no maternal siblings or other relatives are present and only after significant delays. In conclusion, following the loss of their mother, orphaned chimpanzees preferentially associate along pre-existing social bonds, which are typically strongest amongst maternal siblings.

    Siblings' psychosocial adjustment to childhood cancer is poorly understood. This systematic review summarizes findings and limitations of the sibling literature since 2008, provides clinical recommendations, and offers future research directions. MEDLINE/Pubmed, Cumulative Index to Nursing and Allied Health Literature, and PsycINFO were searched for articles related to siblings, psychosocial functioning, and pediatric cancer. After systematic screening, studies meeting inclusion criteria were rated for scientific merit, and findings were extracted and synthesized. In total, 102 studies were included (63 quantitative, 35 qualitative, 4 mixed-methods). Methodological limitations are common. Mean levels of anxiety, depression, and general adjustment are similar across siblings and comparisons, but symptoms of cancer-related posttraumatic stress are prevalent. School-aged siblings display poorer academic functioning and more absenteeism but similar peer relationships as peers. Quality of life findings are mixed. Adult siblings engage in higher levels of risky health behaviors and may have poorer health outcomes than comparisons. Risk factors for poor sibling adjustment include lower social support, poorer family functioning, lower income, non-White race, and shorter time since diagnosis, but findings are inconsistent. Qualitative themes include siblings' maturity, compassion, and autonomy, but also strong negative emotions, uncertainty, family disruptions, limited parental support, school problems, altered friendships, and unmet needs. Despite methodological limitations, research indicates a strong need for sibling support. Clinical recommendations include identifying at-risk siblings and developing interventions to facilitate family communication and increase siblings' social support, cancer-related knowledge, and treatment involvement. Future longitudinal studies focusing on mechanisms and moderators of siblings' adjustment would inform timing and targets of

    Interpersonal relationships both within and outside the family have been a central part of alcohol and substance use research. Many studies have focused on the role of parents and peers; fewer studies have focused on siblings. This paper examined siblings' roles in ATOD use patterns and trajectories in the context of familial and non-familial factors across time. First, intraclass correlations (ICCs) were used to examine the degree to which older siblings' ATOD use was associated with younger siblings' ATOD use. Second, hierarchical regression analyses were conducted to examine the degree to which individual, parent, sibling and peer factors over time were associated with adolescents' and young adults' ATOD use. It should be noted that developmentally proximal predictors were utilized in these models and within-family replication was also examined. Results demonstrate strong associations between older and younger siblings' ATOD use. Moreover, the developmentally proximal sibling variables were predictive of younger sibling ATOD use in the context of other variables across all substances. Study findings are discussed in terms of identifying promising and potentially malleable points of intervention for future investigators. PMID:25484550

    Although previous research has linked sibling relationship experiences to youth’s social competencies with peers, we know little about the role of siblings in youth’s romantic relationship experiences. Drawing on data from a longitudinal sample of 190 families, this study examined the links between sibling experiences and the development of perceived romantic competence from early adolescence into young adulthood (ages 12 to 20). The data were collected from 373 youth (50.7% female) in home interviews on up to 5 annual occasions. Multi-level models tested the moderating role of sibling gender constellation in romantic competence development and the links between (changes in) sibling intimacy and conflict, and romantic competence. The results revealed that youth with same-sex siblings showed no change in their perceived romantic competence, but those with opposite-sex siblings exhibited increases in romantic competence over time. Controlling for parent-child intimacy, at times when youth reported more sibling intimacy, they also reported greater romantic competence, and youth with higher cross-time average sibling conflict were lower in romantic competence, on average. This study illustrates that sibling experiences remain important in social development into early adulthood and suggests directions for application and future research. PMID:25183625

    Anorexia nervosa (AN) is often first diagnosed in the adolescent years. The treatment with the greatest evidence during this time is family-based treatment (FBT). In FBT, siblings are expected to attend treatment sessions; however, sibling well-being during this time has not been well researched. This study aimed to explore sibling well-being when the ill child was initially diagnosed with AN and after FBT had been completed. Eighty-five parents and 55 siblings of adolescents with AN completed the Strengths and Difficulties Questionnaire at diagnosis. In addition, 88 parents and 46 siblings completed the Strengths and Difficulties Questionnaire after finishing treatment. Mothers and fathers reported siblings to have lower levels of conduct problems in comparison with population norms. Mothers also reported lower levels of prosocial behaviours. Siblings reported higher levels of emotional difficulties and hyperactivity in comparison with their peers. There were no differences in reported psychosocial well-being of siblings between diagnosis and following FBT. Siblings of adolescents with AN have poorer psychosocial adjustment than their peers, both before and after FBT. Clinicians and parents are encouraged to be aware of sibling difficulties and seek additional support if required. Copyright © 2016 John Wiley & Sons, Ltd and Eating Disorders Association.

Data was collected from 1755 siblings of children with ASD whose families participated in the Simons Simplex Collection; siblings ranged in age from 3 to 18 years (M=9 years). Male siblings were at increased risk for sub-clinical anxiety problems during middle childhood. Parental history of anxiety disorders, higher maternal pragmatic language, and more proband behavior problems predicted higher anxiety. While siblings overall did not show elevated anxiety symptoms, higher rates of sub-clinical anxiety problems among males and siblings in middle childhood are cause for concern. PMID:23076507

    To understand the stigma perspective of siblings of children with major burn injury. A mixed method, qualitative-dominant study was conducted. The life story method was used for the qualitative portion. Only narratives from those family members describing the sibling's appearance change were used (N = 18 participants). Stigma experienced by siblings was first described by parents or noninjured siblings; they described how the sibling with changed appearance was stared at, ridiculed, or teased when they entered a new social situation. Only when specifically asked did the children with burn injury talk about their problems, saying, "This always happens when I go somewhere new." Children with changed appearance focused on normalizing their lives in a positive way. Oftentimes, it was a parent or noninjured sibling who would describe manifestations of stigma and ways they tried to protect the child with burn injury. ©2013 The Author(s) ©2013 American Association of Nurse Practitioners.

    Developmental disabilities and severe mental illness are costly to the affected individual and frequently to their family as well. Little studied are their nondisabled siblings. Here we examine major life course outcomes (education, employment, and marriage) of these siblings in adulthood using data from the Wisconsin Longitudinal Study. Our sample comprises 113 individuals with developmental disabilities and 337 of their nondisabled siblings; 97 individuals with mental illness and 235 of their nondisabled siblings; and 17,126 unaffected comparison group members. We find that siblings of individuals with mental illness have less education and less employment than the unaffected comparison group, whereas those who have a sibling with developmental disabilities had normative patterns of education and employment, but less marriage and more divorce. Robustness tests incorporating genetic data do not change the conclusions based on the nongenetic analyses. PMID:24607704

    Siblings of people with intellectual and developmental disabilities (IDD) often assume key roles to support their brothers and sisters. For people with more significant support needs, siblings may undertake additional roles and responsibilities throughout their lives. The purpose of the present study was to identify and describe the roles of adult siblings who have a brother or sister with severe IDD. Seventy-nine adult siblings from 19 to 72 years of age completed an online survey with open-ended questions about the roles they play in their relationships with their brother or sister. Thematic analysis resulted in identification of several roles including caregiver, friend (social partner), advocate, legal representative, sibling (teacher/role model), leisure planner and informal service coordinator. Siblings assume key roles in the lives of people with IDD and need support from family and professionals to perform these roles. © 2017 John Wiley & Sons Ltd.

    The development of gender role qualities (attitudes, personality, leisure activities) from middle childhood to early adolescence was studied to determine whether siblings' gender role qualities predicted those of their sisters and brothers. Participants were 198 firstborn and second-born siblings (Ms = 10 years 9 months and 8 years 3 months, respectively, in Year 1) and their parents. Families were interviewed annually for 3 years. Firstborn siblings' qualities in Year 1 predicted second-born children's qualities in Year 3 when both parent and child qualities in Year 1 were controlled, a pattern consistent with a social learning model of sibling influence. Parental influence was more evident and sibling influence less evident in predicting firstborns' qualities; for firstborns, sibling influences suggested a de-identification process.

    This study utilized actor-partner interdependence modeling to examine the bidirectional effects of younger (M age  = 18 months) and older siblings (M age  = 48 months) on later empathy development in a large (n = 452 families), diverse (42% immigrant) Canadian sample. Controlling for parenting, demographic characteristics, sibling relationship quality, and within-child stability in empathic concern, both younger and older siblings' observed empathic concern uniquely predicted relative increases in the other's empathy over a period of 18 months. The strength of the partner effects did not differ by birth order. Sex composition moderated the younger sibling partner effect, whereas age gap moderated the older sibling partner effect.

    Despite the prevalence of studies showing increased stress among mothers of individuals with autism spectrum disorders, few studies have examined general stress among typically developing siblings. This study used an online survey to compare the levels of self-reported stress between adolescent siblings of individuals with autism spectrum disorder and Down syndrome. Sibling of individuals with autism reported significantly more overall stress than did siblings of individuals with Down syndrome, as well as more stress specifically attributed to the brother/sister with autism. The two groups did not differ on perceived social support from family and friends. In linear regression models, the disability group (autism vs Down syndrome) was significantly related to sibling stress above and beyond target child behavior problems, perceived social support, and demographic factors. These results help shed light on the daily experiences of adolescent siblings of individuals with autism and call for more research into potential interventions to address increased stress levels.

    Sibling programming is an important part of a prevention framework, particularly for youth in foster care. After children are removed from their families and placed into foster care in the aftermath of maltreatment, the sibling relationship is often the most viable ongoing relationship available to the child, and may be critical to a youth's sense of connection, emotional support, and continuity. The promise of dyadic sibling programming in particular rests on the ability of interventions to enhance the quality of sibling relationships; yet little research exists that suggests that sibling interventions can improve relationship quality among foster youth. The primary aim of the current study was to examine the effects of a specific dyadic sibling-focused intervention for older and younger siblings on sibling relationship quality. One hundred sixty four dyads (328 youth) participated in the study, with each dyad consisting of an older sibling between 11 and 15 years of age at baseline and a younger sibling separated in age by less than 4 years. Hierarchical linear models were applied to self-reported, observer-reported and observational data over the 18-month study period. Findings suggest that the sibling intervention holds promise for improving sibling relationship quality among youth in foster care. Implications and future directions for research are discussed.

    2015-11-01

    Siblings play an important role in relational and individual development throughout adolescence and beyond through several mechanisms. Central to this role and the mechanisms of sibling influence is the notion that siblings provide a constant and meaningful frame of reference for social comparison. This study examined the role of sibling social comparison orientation, or the tendency of siblings to compare themselves to one another, on youths' depressive symptoms and family relationships, both directly and by moderating links with parental differential treatment. Participants included 338 youth (M age = 18.34, SD = 1.03; 52 % female). Using hierarchical ordinary least squares regression, we found that a higher sibling social comparison orientation was linked with more depressive symptoms, warmer sibling relationships, and more sibling conflict. Additionally, sibling social comparison orientation moderated links of parental differential treatment with depressive symptoms and prosocial behavior toward family members such that effects were more salient for those with a high comparison orientation. The discussion focuses on the role of sibling comparison in the ways that siblings influence one another's development.

    Waardenburg syndrome Type I (WS1) is an autosomal dominant disorder that has previously been associated with mutations in the PAX3 gene on the 2q35 region. In this study, we used an Iranian WS1 family with seven affected individuals in three generations. The phenotypic characteristics of the family include sensorineural deafness, dystopia canthorum, hypopigmented skin patches of the upper limbs, congenital white forelock, confluent white eyebrows, nonpigmented iris, poliosis, and hypopigmentation of the retina. Herein, we report a previously unidentified single-base substitution in exon II (C-->T at position 218) that results in a change of serine to leucine (S73L) in this family. This change was not observed in 100 chromosomes of healthy unrelated individuals. This mutation is within the PAX3 paired domain region, a structure that is highly conserved and implicated in DNA binding. This is the first identification of a PAX3 mutation for this phenotype in the Iranian population. This also provides additional confirmation for the involvement of this gene in the etiology of WS1.

    Affect regulation skills develop in the context of the family environment, wherein youths are influenced by their parents', and possibly their siblings', regulatory responses and styles. Regulatory responses to sadness (mood repair) that exacerbate or prolong dysphoria (maladaptive mood repair) may represent one way in which depression is transmitted within families. We examined self-reported adaptive and maladaptive mood repair responses across cognitive, social and behavioural domains in Hungarian 11- to 19-year-old youth and their parents. Offspring included 214 probands with a history of childhood-onset depressive disorder, 200 never depressed siblings and 161 control peers. Probands reported the most problematic mood repair responses, with siblings reporting more modest differences from controls. Mood repair responses of parents and their offspring, as well as within sib-pairs, were related, although results differed as a function of the regulatory response domain. Results demonstrate familiality of maladaptive and adaptive mood repair responses in multiple samples. These familial associations suggest that relationships with parents and siblings within families may impact the development of affect regulation in youth.

    As adults with Down syndrome live increasingly longer lives, their adult siblings will most likely assume caregiving responsibilities. Yet little is known about either the sibling relationship or the general functioning of these adult siblings. Using a national, web-based survey, this study compared adult siblings of individuals with Down syndrome to siblings of individuals with autism in terms of a potential 'Down syndrome advantage' and changes across age of the brother/sister with disabilities. Two groups were examined, siblings of persons with Down syndrome (n = 284) and with autism (n = 176). The Adult Sibling Questionnaire measured the number and length of contacts between siblings and their brothers/sisters with disabilities; the warmth, closeness and positiveness of the sibling relationship; and the sibling's overall levels of perceived health, depression and rewards of being a sibling. Compared with siblings of brothers/sisters with autism, siblings of brothers/sisters with Down syndrome showed closer, warmer sibling relationships, along with slightly better health, lower levels of depressive symptoms and more contacts. Across age groups of the brother/sister with disabilities, both groups showed lessened contacts, with less close sibling relationships occurring when brothers/sisters with disabilities were aged 30-44 years and 45 years and older (in Down syndrome) and 45 years and older (in autism). Within both groups, closer sibling relationships were associated with more frequent and lengthy contacts, brothers/sisters with disabilities who were better at maintaining friendships and had lower levels of behavioural/emotional problems, and siblings who felt themselves more rewarded by being a sibling to a brother/sister with disabilities. In line with earlier work on families of children with disabilities, this study shows an advantage for siblings of adults with Down syndrome, in terms of both sibling relationships and of slightly better health and

    Genealogies contain information on the prevalence of different sibling types that result from past reproductive behavior. Full sibling sets stem from stable monogamy, paternal half siblings primarily indicate male reproductive skew, and maternal half siblings reflect unstable pair bonds. Full and half sibling types are calculated for a total of 61,181 siblings from published genealogies for 80 small-scale societies, including foragers, horticulturalists, agriculturalists, and pastoralists from around the world. Most siblings are full (61%) followed by paternal half siblings (27%) and maternal half siblings (13%). Paternal half siblings are positively correlated with more polygynous marriages, higher at low latitudes, and slightly higher in nonforagers, Maternal half sibling fractions are slightly higher at low latitudes but do not vary with subsistence. Partible paternity societies in Amazonia have more paternal half siblings indicating higher male reproductive skew. Sibling counts from genealogies provide a convenient method to simultaneously investigate the reproductive skew and pair-bond stability dimensions of human mating systems cross-culturally. Am. J.

    To investigate school absenteeism among childhood cancer survivors and their siblings and examine factors related to absenteeism in survivors. A cross-sectional study was conducted among consecutive cancer survivors attending a large pediatric cancer survivor clinic. Absenteeism rates were obtained for survivors and their closest in age sibling from school report cards. Absenteeism was compared with a population control group of 167752 students using 1-sample t tests. The Child Vulnerability Scale, Pediatric Quality of Life Inventory, and Behavior Assessment System for Children were administered to survivors. Univariate and multiple regression analyses assessed variables associated with days absent. One hundred thirty-one survivors (median age at assessment: 13.4 years, range 8.0-19.2; median age at diagnosis: 9.4 years, range 4.3-17.3) and 77 siblings (median age at assessment: 13 years, age range 7-18) participated. Survivors and siblings missed significantly more school days than the population control group (mean ± SD: 9.6 ± 9.2 and 9.9 ± 9.8 vs 5.0 ± 5.6 days, respectively, P sibling pairs (N = 77), there was no difference in absenteeism (9.6 ± 9.2 vs 9.9 ± 9.8 days, P = .85). Absenteeism in survivors was significantly associated with a low Pediatric Quality of Life Inventory Physical Health Summary Score (P = .01). Parents' perception of their child's vulnerability and emotional and social functioning were not associated with absenteeism. Childhood cancer survivors and siblings miss more school than the general population. The only predictor of absenteeism in survivors is poor physical quality of health. More research should be devoted to school attendance and other outcomes in siblings of childhood cancer survivors. Copyright © 2013 Mosby, Inc. All rights reserved.

    Growing Right Onto Wellness (GROW) is a randomized controlled trial that tests the efficacy of a family-centered, community-based, behavioral intervention to prevent childhood obesity among preschool-aged children. Focusing on parent-child pairs, GROW utilizes a multi-level framework, which accounts for macro (i.e., built-environment) and micro (i.e., genetics) level systems that contribute to the childhood obesity epidemic. Six hundred parent-child pairs will be randomized to a 3-year healthy lifestyle intervention or a 3-year school readiness program. Eligible children are enrolled between ages 3 and 5, are from minority communities, and are not obese. The principal site for the GROW intervention is local community recreation centers and libraries. The primary outcome is childhood body mass index (BMI) trajectory at the end of the three-year study period. In addition to other anthropometric measurements, mediators and moderators of growth are considered, including genetics, accelerometry, and diet recall. GROW is a staged intensity intervention, consisting of intensive, maintenance, and sustainability phases. Throughout the study, parents build skills in nutrition, physical activity, and parenting, concurrently forming new social networks. Participants are taught goal-setting, self-monitoring, and problem solving techniques to facilitate sustainable behavior change. The GROW curriculum uses low health literacy communication and social media to communicate key health messages. The control arm is administered to both control and intervention participants. By conducting this trial in public community centers, and by implementing a family-centered approach to sustainable healthy childhood growth, we aim to develop an exportable community-based intervention to address the expanding public health crisis of pediatric obesity. © 2013.

  13. Evidence that meiotic pairing starts at the telomeres: Molecular analysis of recombination in a family with a pericentric X chromosome inversion

    Recent studies in yeast have shown that telomeres rather than centromeres lead in chromosome movement just prior to meiosis and may have a role in recombination. Cytological studies of meiosis in Drosophila and mice have shown that in pericentric inversion heterozygotes there is lack of loop formation, with recobmination seen only outside the inversion. In a family with Duchenne muscular dystrophy (DMD) we recognized that only affected males and carrier females had a pericentric X chromosome inversion (inv X(p11.4;q26)). Since the short arm inversion breakpoint was proximal to the DMD locus, it could not be implicated in the mutational event causing DMD. There was no history of infertility, recurrent miscarriages or liveborn unbalanced females to suggest there was recombination within the inversion. We studied 22 members over three generations to understand the pattern of meiotic recombination between the normal and the inverted X chromosome. In total, 17 meioses involving the inverted X chromosome in females were studied by cytogenetic analysis and 16 CA repeat polymorphisms along the length of the X chromosome. Results: (a) There was complete concordance between the segregation of the DMD mutation and the inverted X chromosome. (b) On DNA analysis, there was complete absence of recombination within the inverted segment. We also found no recombination at the DMD locus. Recombination was seen only at Xp22 and Xq27-28. (c) Recombination was seen in the same individual at both Xp22 and Xq27-28 without recombination otherwise. Conclusions: (1) Pericentric X inversions reduce the genetic map length of the chromosome, with the physical map length being normal. (2) Meiotic X chromosome pairing in this family is initiated at the telomeres. (3) Following telomeric pairing in pericentric X chromosome inversions, there is inhibition of recombination within the inversion and adjacent regions.

    Full Text Available Many individuals with Autism Spectrum Disorder (ASD have unique characteristics and very little is known about how these characteristics may influence the family and the behavioural, social and emotional adjustment of their siblings. The purpose of the current study is to focus on the siblings and to review the literature related to the behavioural, social and emotional adjustment of siblings of individuals with ASD. We have identified and analysed 24 articles to find the relevant results that may help us to understand the needs of these siblings. The findings suggest mixed results but they also bring to light a number of risk factors that could have an impact on the entire family and particularly on the siblings of children with ASD.

    To compare the perinatal outcome of singleton siblings conceived differently. National population-based registry study. Denmark, from 1994 to 2008. Pairs of siblings (13,692 pairs; n = 27,384 children) conceived after IVF, intracytoplasmatic sperm injection (ICSI), frozen embryo replacement (FER), or spontaneous conception subcategorized into five groups according to succession: [1] IVF-ICSI vs. spontaneous conception (n = 7,758), [2] IVF-ICSI vs. FER (n = 716), [3] FER vs. FER (n = 34), [4] IVF-ICSI vs. IVF-ICSI (n = 2,876), and [5] spontaneous conception vs. spontaneous conception (n = 16,000). Observations were obtained from national registries. Birth weight, gestational age, low birth weight (children compared with their spontaneously conceived siblings. FER children were 167 g (95% CI, 90-244] heavier than siblings born after replacement of fresh embryos. The difference in birth weight between firstborn and second born sibling depended on order of conception method. Higher risk of low birth weight with (odds ratio [OR], 1.4; 95%CI, 1.1-1.7] and preterm birth (OR, 1.3; 95% CI, 1.1-1.6] was observed in IVF/ICSI compared with spontaneous conception. When differentiating between order and mode of conception, it seems that assisted reproductive technology plays a role in mean birth weight and risk of low birth weight and preterm birth. Birth weight was higher in siblings born after FER compared with fresh embryos replacement. Copyright © 2011 American Society for Reproductive Medicine. Published by Elsevier Inc.

    Matthews, Nicole L; Goldberg, Wendy A

    2018-04-01

    The two prior studies that have examined associations between the sibling constellation and theory of mind in autism spectrum disorder yielded discrepant findings. Thus, efforts to better understand the sibling-theory of mind link in autism spectrum disorder are necessary. This study examined a sample of prekindergarten- and kindergarten-aged (i.e. 4-6 years) typically developing children ( n = 39) and verbal children with autism spectrum disorder ( n = 61). Sibling presence, number of siblings, and having younger and older siblings were positively associated with theory of mind in typically developing children, but not in the full sample of children with autism spectrum disorder. However, in the subgroup of children with autism spectrum disorder without sibling recurrence, the presence of at least one older sibling was positively associated with theory of mind. Findings expand previous limited research on the sibling-theory of mind link in children with autism spectrum disorder by demonstrating a potential difference in the influence of the sibling constellation between children from simplex and multiplex families.

    O'Brien, Karen; Slaughter, Virginia; Peterson, Candida C

    2011-06-01

    Research indicates that having child siblings is positively associated with theory of mind (ToM) in typically developing children. As ToM is important to everyday social behaviours it is important to extend this research to examine whether there are similar sibling effects for children with autism spectrum disorders (ASD). Theory of mind and executive functioning abilities of 60 children clinically diagnosed with ASD were assessed with batteries of standard tasks. Verbal mental age (VMA) and severity of autism symptoms were also measured together with number of child-aged siblings (1 to 12 years) and position in the sibling constellation. Having older siblings was a significant negative predictor of ToM performance for children with ASD, even after controlling for age, VMA, executive function and autism symptom severity. A weaker ToM benefit of younger siblings was not statistically significant independently of control variables. In sharp contrast to findings for typically developing preschoolers, having an older sibling was a disadvantage for ToM development in children with ASD. Conceivably, older siblings may over-compensate for their younger ASD siblings in social interactions, thereby limiting opportunities for social-cognitive growth. Parental attitudes, family resources, cultural norms and access to educational interventions may also conceivably be relevant and clearly warrant further research. © 2011 The Authors.

    The aim of the present study was to examine whether adolescents of Moroccan and Dutch origin differ concerning sibling relationship quality and to examine whether the associations between quality of the sibling relationship and level and change in externalizing and internalizing problem behavior are comparable for Moroccan and Dutch adolescents. Five annual waves of questionnaire data on sibling support and conflict as well as externalizing problems, anxiety and depression were collected from 159 ethnic Moroccan adolescents (Mage = 13.3 years) and from 159 ethnic Dutch adolescents (Mage = 13.0 years). Our findings demonstrated significant mean level differences between the Moroccan and Dutch sample in sibling relationship quality, externalizing problems, and depression, with Moroccan adolescents reporting higher sibling relationship quality and less problem behavior. However, effects of sibling relationship quality on externalizing problems, anxiety, and depression were similar for the Moroccan and Dutch samples. Sibling support was not related to level of externalizing problems, nor to changes in externalizing problems, anxiety, and depression. Additionally, more sibling conflict was related to a higher starting level of and faster decreases in problem behaviors. Our results support the ethnic equivalence model, which holds that the influence of family relationships is similar for different ethnic groups. Moreover, sibling support and conflict affect both the level and the fluctuations in problem behavior over time in specific ethnic groups similarly. Implications for future studies and interventions are subsequently discussed.

    Although many siblings experience distress after a child's cancer diagnosis, their psychosocial functioning is seldom assessed in clinical oncology settings. One barrier to systematic sibling screening is the lack of a validated, sibling-specific screening instrument. Thus, this study developed sibling-specific screening modules in English and Spanish for the Psychosocial Assessment Tool (PAT), a well-validated screener of family psychosocial risk. A purposive sample of English- and Spanish-speaking parents of children with cancer (N = 29) completed cognitive interviews to provide in-depth feedback on the development of the new PAT sibling modules. Interviews were transcribed verbatim, cleaned, and analyzed using applied thematic analysis. Items were updated iteratively according to participants' feedback. Data collection continued until saturation was reached (i.e., all items were clear and valid). Two sibling modules were developed to assess siblings' psychosocial risk at diagnosis (preexisting risk factors) and several months thereafter (reactions to cancer). Most prior PAT items were retained; however, parents recommended changes to improve screening format (separately assessing each sibling within the family and expanding response options to include "sometimes"), developmental sensitivity (developing or revising items for ages 0-2, 3-4, 5-9, and 10+ years), and content (adding items related to sibling-specific social support, global assessments of sibling risk, emotional/behavioral reactions to cancer, and social ecological factors such as family and school). Psychosocial screening requires sibling-specific screening items that correspond to preexisting risk (at diagnosis) and reactions to cancer (several months after diagnosis). Validated, sibling-specific screeners will facilitate identification of siblings with elevated psychosocial risk.

    2007-06-01

    The authors examined the quality of sibling relationships in childhood as a predictor of major depression in adulthood. Study subjects were 229 men selected for mental and physical health and followed from ages 20 through 50 and beyond as part of a study of adult psychosocial development. Data were obtained from interviews with participants and their parents at intake and from follow-up interviews and self-report questionnaires completed by participants at regular intervals. These data were used to rate the quality of relationships with siblings, the quality of parenting received in childhood, and family history of depression as well as the occurrence, by age 50, of major depression, alcoholism, and use of mood-altering drugs (tranquilizers, sleeping pills, and stimulants). Poorer relationships with siblings prior to age 20 and a family history of depression independently predicted both the occurrence of major depression and the frequency of use of mood-altering drugs by age 50, even after adjustment for the quality of childhood relationships with parents. Poor relationships with parents in childhood did not predict the occurrence of depression by age 50 when family history of depression and the quality of relationships with siblings were taken into account. Quality of sibling relationships and family history of depression did not predict later alcohol abuse or dependence. Poor sibling relationships in childhood may be an important and specific predictor of major depression in adulthood. Further study of links between childhood sibling relationships and adult depression is warranted.

    This pilot study explores the degree of solidarity felt between full and half siblings who are raised in a Mormon Fundamentalist polygamous community. The community under study is unique in that, at the level of official culture, it actively promotes full and half sibling solidarity through an ethos that strives to downplay genetic differences in favor of a harmonious family living together in one household. This community is an ideal cultural setting in which to examine the suitability of inclusive fitness theory for understanding the factors that promote family cohesion, sibling solidarity, and rivalry. Our main question becomes: is the degree of sibling solidarity a manifestation of genetic closeness or a natural byproduct of emotional closeness that arises from being raised together? We found evidence for more solidarity between full siblings than between half siblings. Our data suggest that, despite the force of religious ideals, and notwithstanding the continued close physical proximity of half siblings in the polygamous family, there is a pronounced clustering of feeling and affection in the polygamous family that is consistent with inclusive fitness theory.

    A number of methodological weaknesses have contributed to our relatively poor understanding of the impact on children of having a brother or sister with a disability. These include a focus on poor adjustment, using multidiagnostic groups, inadequate matching, and a failure to consider the perspectives of children and parents together. This study compared the adjustment of 53 siblings of a child with Down syndrome with a comparison group of siblings of children who were developing typically. Children were matched on a case-by-case basis for gender, age and position in family. Families were matched for family size and father's occupation. The age range of the target siblings was 7-14 years. Data were gathered from mothers, fathers and siblings. There were no significant differences between the groups on adjustment measures. These included parent perceptions of externalizing and internalizing behaviours, parent perceptions of sibling competence, and sibling perceptions of their own competence and self-worth. Associations between measures of adjustment and child reports of their contribution to household functioning depended on sex rather than group membership. There was an association between parental reports of externalizing behaviour and sibling relationships with the brother/sister closest in age. Having a brother or sister with Down syndrome does not inevitably lead to poor adjustment. Examination of within-family processes would appear to be more useful in identifying children at risk than merely group membership.

    2009-01-01

    The purpose of this study was to examine the relationships of sexual minority youth and their siblings. The participants were 56 lesbian, gay, bisexual, or transgender individuals ranging in age from 18 to 24 years, who reported information about a total of 107 siblings. Respondents completed a demographic data questionnaire as well as adapted versions of the Sibling Closeness Scale (SCS) and the Sibling Approval of Sexual Behavior Scale (SASBS) to describe their relationship with each of their siblings. Analyses examined birth order and gender in relation to outness to siblings as well as sibling closeness and approval. Results provide information about disclosure of LGBT status to siblings, elements of closeness and acceptance in sibling relationships of sexual minority youth, and the significance of gender and birth order in these sibling relationships.

    Researchers document the emotional impact of epilepsy on the child with seizures. Minimal data are available examining the effects of epilepsy on the siblings of children with seizures. Twenty children whose siblings had either frequent seizures or infrequent seizures were matched by age, gender, and birth order to control subjects with no chronic illness. These three groups were compared. Self-esteem, behavioral and social functioning, and family stress were measured by the Piers-Harris Self-Concept Scale, Child Behavior Checklist, and Family Inventory of Life Events. The siblings of children with epilepsy completed the Sibling Concern About Seizure Scale to define and measure their concerns surrounding epilepsy. There is no statistical difference in self-esteem or social functioning among the three groups. There is a trend toward increased incidence of externalizing behavior in siblings of children with frequent seizures. Data indicate a trend toward siblings of children with frequent seizures having more concerns about epilepsy than siblings of children with infrequent seizures. There is significantly more stress in families of children with frequent seizures compared to families of children with infrequent seizures and families of children with no chronic illness. Although there were no significant differences in the self-esteem, behavior, socialization, and concerns between the siblings in the family when compared to the control group or to each other, there were trends in the results that may be of clinical significance. These issues, along with the level of family stress, should be considered when coordinating and providing care to families of children with intractable epilepsy.

  19. Are there shared environmental influences on adolescent behavior? Evidence from a study of adoptive siblings.

    2009-09-01

    The failure to identify specific non-shared environmental influences on behavior coupled with the belief that shared environmental factors contribute minimally to individual differences in behavior has led to the concern that major environmental determinants of behavior may be idiosyncratic, and therefore undetectable. We used data on adoptive (N = 246) and biologically related (N = 130) same-sex sibling pairs (mean ages = 16.1 years older sibling; 13.8 years younger sibling) from the Sibling Interaction and Behavior Study (SIBS) to determine whether non-idiosyncratic environmental factors shared by siblings contributed to individual differences in a diverse set of behavioral outcomes. Evidence for shared environmental influence was sought for eight composite measures covering a wide array of adolescent functioning: Academic Achievement, Total IQ, Substance Use Disorders, Externalizing Disorders, Internalizing Disorders, Peer Groups, Disinhibited Personality, and Negative Emotionality. For six of eight composites, significant shared environmental effects, accounting for 14-22% of the variance, were observed for these same-sex sibling pairs. These findings support the use of adoptive sibling designs to directly estimate shared environmental effects and implicate the existence of systematic environmental influences on behavior that are potentially detectable.

  20. Land inheritance establishes sibling competition for marriage and reproduction in rural Ethiopia.

    Intergenerational transfer of wealth has been proposed as playing a pivotal role in the evolution of human sibling relationships. Sibling rivalry is assumed to be more marked when offspring compete for limited heritable resources, which are crucial for reproductive success (e.g., land and livestock); whereas in the absence of heritable wealth, related siblings may cooperate. To date, comparative studies undertaken to support this evolutionary assumption have been confounded by other socioecological factors, which vary across populations, e.g., food sharing and intergroup conflict. In this article we explore effects of sibling competition and cooperation for agricultural resources, marriage, and reproduction in one contemporary Ethiopian agropastoralist society. Here recent changes in land tenure policy, altering transfers of land from parents to offspring, present a unique framework to test the importance of intergenerational transfers of wealth in driving sibling competition, while controlling for socioeconomic biases. In households where land is inherited, the number of elder brothers reduces a man's agricultural productivity, marriage, and reproductive success, as resources diminish and competition increases with each additional sibling. Where land is not inherited (for males receiving land directly from the government and all females) older siblings do not have a competitive effect and in some instances may be beneficial. This study has wider implications for the evolution of human family sizes. Recent changes in wealth transfers, which have driven sibling competition, may be contributing to an increased desire for smaller family sizes.

    2006-01-01

    Data from a range of different environments indicate that the incidence of death is not randomly distributed across families but, rather, that there is a clustering of death amongst siblings. A natural explanation of this would be that there are (observed or unobserved) differences across families, for example in genetic frailty, education or living standards. Another hypothesis of considerable interest for both theory and policy is that there is a causal process whereby the death of a child ...

    Feinberg, M E; Neiderhiser, J M; Simmens, S; Reiss, D; Hetherington, E M

    2000-01-01

    This study employs findings from social comparison research to investigate adolescents' comparisons with siblings with regard to parental treatment. The sibling comparison hypothesis was tested on a sample of 516 two-child families by examining whether gender, self-esteem, and emotionality-which have been found in previous research to moderate social comparison-also moderate sibling comparison as reflected by siblings' own evaluations of differential parental treatment. Results supported a moderating effect for self-esteem and emotionality but not gender. The sibling comparison process was further examined by using a structural equation model in which parenting toward each child was associated with the adjustment of that child and of the child's sibling. Evidence of the "sibling barricade" effect-that is, parenting toward one child being linked with opposite results on the child's sibling as on the target child-was found in a limited number of cases and interpreted as reflecting a sibling comparison process. For older siblings, emotionality and self-esteem moderated the sibling barricade effect but in the opposite direction as predicted. Results are discussed in terms of older siblings' increased sensitivity to parenting as well as the report of differential parenting reflecting the child's level of comfort and benign understanding of differential parenting, which buffers the child against environmental vicissitudes evoking sibling comparison processes.

    2015-08-01

    This research aimed to provide new knowledge about the emotional experiences of siblings of children with rare disorders. Qualitative thematic analysis was conducted based on videotapes of 11 support groups for 58 siblings aged 7-17 years (Mage = 11.4 years, SD = 2.4) of children with rare disorders. Participants described contradictory emotions in three main contexts: (1) implications of the disorder (knowledge, medical issues, prognosis); (2) consequences for family life (practical implications, limitations of the child with disorder, perspectives on the sibling relationship); and (3) consequences for social life (reflections about (ab)normality, reactions from others). Passive coping strategies were frequently described relative to active coping strategies. An emerging dilemma for participants was hiding versus sharing emotional experiences. Siblings' emotional experiences are characterized by diverse and contradictory feelings. Interventions to promote emotional health in siblings of children with rare disorder should address this complexity. © The Author 2015.

    2002-12-01

    The detrimental impact of short preceding birth intervals on infant and early childhood mortality is well documented in demographic literature, although the pathways of influence within the relationship remain an area of debate. This paper examines the impact of the length of the preceding birth interval on under-two mortality in India, and examines the pathways through which short preceding birth intervals may lead to an increased risk of mortality. Three mortality periods are examined: neonatal, early post neonatal and late post-neonatal and toddler, using the 1992 Indian National Family Health Survey. A multilevel modelling approach is used to account for the hierarchical nature of the data. The determinants of infants following a short or long birth interval are also examined. The results show that short preceding birth intervals (sibling rivalry is a pathway through which short birth intervals influence mortality, with the death of the previous sibling removing the competition for scarce resources, and resulting in lower risks of mortality than if the previous sibling was still alive. The greatest risks of an infant following a short birth interval are among those whose previous sibling died, high parities, those with young mothers, and those whose previous sibling was breastfed for a short duration.

  9. The time-varying role of the family in student time use and achievement

    Full Text Available Abstract In this paper, I use a unique dataset linking administrative school data with birth records to quantify the importance of time-varying family factors for child achievement and time use. Specifically, I take a model of academic achievement commonly used in the test score literature, and I augment it to include a family-year effect. Identification comes from the large number of sibling pairs observed in the same year. While prior literature has focused on specific shocks, such as job loss, I capture the full set of innovations that are shared across siblings in a given year. The distributions of fixed effects reveal that annual family innovations, relative to what was expected based on the previous year, are more important than teacher assignment for student achievement and also play a substantial role in the time students spend on homework, free reading, and television.

    To study quality of life (QoL) of the siblings of children with chronic neurological disorders. Between 1st August and 30th September, 2013, 50 children aged 12-18 y, whose child sibling was suffering from a chronic neurological disorder, were enrolled (Study group). Fifty age- and sex- matched siblings of apparently non-neurologically affected children were enrolled as controls (Control group). Those with more than one affected child or any affected adult in the family were excluded. QoL was assessed by a validated version of the WHOQOL-BREF in Hindi, and QoL was compared between cases and controls. The disorders in the index cases included cerebral palsy, 18 (15 with epilepsy); autism, 15; mental retardation, 12 and epilepsy, 5. The QoL in all domains was significantly poorer in the study group as compared to the controls. 64% study group children had insufficient knowledge about their sibling's condition. More than 1/4th study subjects faced difficulties in studies, play or work. There was no difference among the groups with regard to number of siblings who had 'dropped from the school'. The QoL of unaffected siblings of children with chronic neurological disorders was significantly impaired. Health-workers may consider including older siblings of neurologically affected children during family-counseling sessions, to provide information and suggest coping strategies. This intervention is likely to improve the functioning of the family unit as a whole.

    2002-03-01

    Associations between sibling conflict in middle childhood and psychological adjustment in early adolescence were studied in a sample of 80 boys and 56 girls. Parents and children provided self-report data about family relationships and children's adjustment. Parents' hostility to children was assessed from videotaped interactions. Results showed that sibling conflict at Time 1 predicted increases in children's anxiety, depressed mood, and delinquent behavior 2 years later. Moreover, earlier sibling conflict at Time 1 accounted for unique variance in young adolescents' Time 2 anxiety, depressed mood, and delinquent behavior above and beyond the variance explained by earlier maternal hostility and marital conflict. Children's adjustment at Time 1 did not predict sibling conflict at Time 2. Results highlight the unique significance of the earlier sibling relationship for young adolescents' psychological adjustment.

    BACKGROUND: Coinfection with hepatitis C virus (HCV) is a poor prognostic factor for human immunodeficiency virus (HIV)-infected patients. We examined whether the increased mortality in these patients is partly explained by a familial excess risk of death. METHODS: Danish HIV-infected patients who...... had had at least 1 HCV test were included (n=3531). In addition, 336,652 population control subjects matched for sex, age, and residency were identified from the Danish Civil Registration System. For both HIV-infected patients and population control subjects, we identified all siblings born after 1951......, with dates of death or emigration. Siblings of HIV-infected patients were classified according to the patients' HCV serostatus. Survival after age 20 years was compared among the groups of siblings. RESULTS: We identified 437 siblings of HIV/HCV-coinfected patients, 1856 siblings of HIV-monoinfected patients...

    We introduce the notion of a Mahonian pair. Consider the set, P^*, of all words having the positive integers as alphabet. Given finite subsets S,T of P^*, we say that (S,T) is a Mahonian pair if the distribution of the major index, maj, over S is the same as the distribution of the inversion number, inv, over T. So the well-known fact that maj and inv are equidistributed over the symmetric group, S_n, can be expressed by saying that (S_n,S_n) is a Mahonian pair. We investigate various Mahonia...

    Greenwell, C M; Brain, P H; Dunn, A L

    2014-04-01

    Metaphyseal osteopathy (MO) was diagnosed in three Australian Kelpie puppies that were presented for veterinary assessment of lameness. The three puppies were siblings. Each was from a different litter by the same breeding pair. The puppy in case one was seen by the authors, and the puppies in cases two and three were patients at other veterinary hospitals. However, the medical records and radiographs were examined and reviewed for this report. Radiographic investigation of the lameness revealed pathognomonic appearance of MO affecting the metaphyseal region of the long bones in all three puppies. The diagnosis was confirmed on histopathology in one patient. MO is considered a disease of large and giant-breed dogs, being rarely reported in non-large-breed dogs, and has not been reported in the Australian Kelpie, which is considered a medium-breed dog. This case series suggests a previously unreported breed predisposition to MO in the Australian Kelpie. © 2014 Australian Veterinary Association.

    Little is known about the impact of cancer on family relationships from the perspective of the pediatric cancer patient and their sibling(s). This study assessed and compared children's experiences of family relationships in patients receiving active cancer therapy, those who have completed therapy, and siblings. A cross-sectional study of children with cancer and their siblings aged 8-17 years old was conducted. Children completed the PROMIS Pediatric Family Relationships short form and the Depressive Symptoms, Anxiety, and Peer Relationships short forms. The Mann-Whitney test assessed differences in Family Relationships scores between therapy groups, while the Wilcoxon signed-rank test assessed differences between patients and siblings. An actor-partner interdependence model (APIM) was used to assess how patient and sibling variables were associated with their own and each others' family relationships. Two hundred and sixty-five children completed the assessments. Siblings of patients on-therapy had worse family relationships than patients on-therapy (P = 0.015). Family relationships of patients off-therapy did not differ from their siblings or the patients on-therapy. Family relationships scores did not differ between the sibling cohorts. The APIM found patient family relationships were impaired when their own peer relationships decreased and when either their own or their siblings had increased depressive symptoms. Sibling family relationships were impaired when their own depression increased, and when the patient counterpart was female, younger age, had less depressive symptoms, more anxiety or a diagnosis of leukemia/lymphoma (compared to solid tumor). Based on these findings, increased psychosocial resources for patients and siblings of children undergoing cancer therapy may be warranted. © 2018 The Authors.

    Although the sibling relationship is a unique one, the effects of the number and type of siblings on mental health among adolescents have not been reported. Japanese children (total, 9276; boys, 4654; girls, 4622), all 12 years old, and from the Japanese Toyama Birth Cohort Study, were followed up until 2002. Subject self-reported mental health was obtained from the Japanese version of the Dartmouth Primary Care Co-operative Project (COOP) charts. The associations between number and type of siblings and self-reported mental health were examined. There was a significant difference in mental health between different sibling pairs, with brother pairs and brother/sister pairs having a positive effect on adolescent mental health, compared with those in sister pairs. Girls with brothers had better self-reported mental health than those without. The adjusted OR of good mental health was 1.44 (95%CI:1.00-2.08) for those with an older brother and 1.67 (95%CI: 1.17-2.38) for those with a younger brother compared with those without. Boys with a younger sister had a higher OR of good self-reported health than those without (OR, 1.62; 95%CI: 1.08-2.43). Children with siblings had better mental health status than those without, which has practical implications for Asian countries and worldwide considering the declining fertility. © 2015 Japan Pediatric Society.

    This study examined the role of sibling and friend characteristics in Mexican-American youth's gender-typed characteristics (i.e., attitudes, interests, and leisure activities) in early versus middle adolescence using a sibling design. Mexican-American 7th graders (M = 12.51 years; SD = .58) and their older siblings (M = 15.48 years; SD = 1.57) from 246 families participated in home interviews and a series of seven nightly phone calls. Results revealed that younger/early adolescent siblings reported more traditional gender role attitudes than their older/middle adolescent siblings and older brothers were more traditional in their attitudes than older sisters. When comparing siblings' gender-typed interests and leisure activities, boys reported more masculine orientations than girls and girls reported more feminine orientations than boys. Older brothers' gender-typed characteristics were associated with the amount of time spent with and gender characteristics of their friendship group, but for younger brothers, sibling characteristics were associated with their gender-typed characteristics. In contrast, both sibling and friendship characteristics were significantly associated with older and younger sisters' gender-typed characteristics. The discussion addressed the different correlates of older and younger sisters' and brothers' gender-typed characteristics.

    Although many studies document an association between attention-deficit/hyperactivity disorder (ADHD) and intellectual disability (ID), little is known about the etiology of this comorbidity and how it should be addressed in clinical settings. We sought to clarify this issue. All individuals born in Sweden between 1987 and 2006 (n = 2,049,587) were identified using the Medical Birth Register (MBR). From this we selected 7 cohorts of relatives: 1,899,654 parent-offspring pairs, 4,180 monozygotic twin pairs, 12,655 dizygotic twin pairs, 914,848 full sibling pairs, 136,962 maternal half-sibling pairs, 134,502 paternal half-sibling pairs, and 2,790,164 full cousin pairs. We used within-individual and within-family analyses to assess the association between ADHD and ID. Individuals with ID were at increased risk for ADHD compared to those without ID, and relatives of participants with ID were at increased risk of ADHD compared with relatives of those without ID. The magnitude of this association was positively associated with the fraction of the genome shared by the relative pair and was lower for severe compared with mild and moderate ID. Model-fitting analyses demonstrated that 91% of the correlation between the liabilities of ADHD and ID was attributable to genetic factors. These data provide evidence that nearly all of the comorbidity between ADHD and ID can be attributed to genetic factors, which has implications for diagnostic practice.

    BACKGROUND: Co-infection with hepatitis C in HIV-infected individuals is associated with 3- to 4-fold higher mortality among these patients' siblings, compared with siblings of mono-infected HIV-patients or population controls. This indicates that risk factors shared by family members partially...... account for the excess mortality of HIV/HCV-co-infected patients. We aimed to explore the causes of death contributing to the excess sibling mortality. METHODOLOGY AND PRINCIPAL FINDINGS: We retrieved causes of death from the Danish National Registry of Deaths and estimated cause-specific excess mortality......-years, compared with siblings of matched population controls. Substance abuse-related deaths contributed most to the elevated mortality among siblings [EMR = 2.25 (1.09-3.40)] followed by unnatural deaths [EMR = 0.67 (-0.05-1.39)]. No siblings of HIV/HCV co-infected patients had a liver-related diagnosis...
