Interpersonal responses among sibling dyads tested for BRCA1/BRCA2 gene mutations.

OBJECTIVE: The familial context plays an important role in psychosocial responses to genetic testing. The purpose of this study was to compare sibling pairs with different combinations of BRCA1/BRCA2 test results on measures of affect, interpersonal responses, and physiological reactions. DESIGN: Forty-nine sibling dyads with different combinations of BRCA1/BRCA2 test results (i.e., mixed, positive, negative) completed a questionnaire, and 35 of the dyads also participated in a laboratory-based discussion of genetic testing. MAIN OUTCOME MEASURES: The primary outcome variables included participant reports of supportive actions toward their sibling, state anger and anxiety, perceptions of sibling behavior, and electrodermal responses. RESULTS: Compared to positive and negative dyads, mixed pairs reported less friendly general support actions, noted more anger, and perceived their sibling to be less friendly and more dominant during the interactions. In comparisons between same-result (i.e., positive, negative) pairs, positive dyads reported more dominant support behaviors and perceived their sibling to be friendlier during the interactions. CONCLUSION: Data suggest that siblings who have different test results may experience more interpersonal strain than siblings who have the same test result. Future research on genetic testing and family relationships can expand upon these findings.     

Children's perceptions of the sibling relationship in middle childhood: Connections within and between family relationships

Although sibling warmth and hostility have been shown to be statistically independent, they are intertwined in children's everyday experiences. We developed a multidimensional characterization of children's perceptions of their sibling relationships and examined differences in other family relationship measures as a function of different combinations of sibling hostility and warmth. Participants included 91 firstborn children between 10 and 11 years of age with younger siblings between 6 and 10 years of age. Children reported their levels of satisfaction, intimacy, and rivalry in their sibling relationships and their satisfaction with parent-child relationships. Parents rated their marriages. As compared with children in families with “affect-intense” sibling relationships (high hostility/high warmth), children in “hostile” sibling relationships (high hostility/low warmth) rated their sibling and parent-child relationships more negatively, and their parents rated their marriages more negatively. Results are discussed in terms of the role of hostility in sibling experiences and the importance of understanding multidimensional patterns in the sibling relationship.     

Differences in nonshared individual, school, and family variables between delinquent and nondelinquent Hmong adolescents

The purpose of the current study was to determine whether there were differences between Hmong immigrant siblings on multiple nonshared individual, school, and family variables. Participants were 58 sibling pairs (29 delinquent pairs and 29 nondelinquent pairs), who ranged in age from 13 to 21 years. There were 11 pairs of boys, 3 pairs of girls, and 15 pairs of opposite-sex siblings. Results of a multivariate analysis of variance indicated that delinquent and nondelinquent sibling groups were significantly different in participation in organized activities, antisocial attitudes, delinquent behaviors, school truancy, school performance, and parents' labeling. The findings have implications for future research on sibling delinquency in Hmong immigrant families and for program development and delivery.     

School Aged Children’s Experiences 7 and 13 Months Following a Sibling’s Death

This study described 6-year to 12-year-old children’s responses 7 and 13 months after siblings’ NICU/PICU/ED death. Using semi-structured interviews, at 7 months, children were asked about events around their sibling’s death. At both 7 and 13 months, children were asked about their thoughts and feelings about the deceased, concerns or fears, and life changes since the death. Thirty one children (58% female), recruited from four South Florida hospitals and Florida obituaries, participated. Children’s mean age was 8.4 years; 64.5% were Black, 22.5% Hispanic, 13% White. Interviews were analyzed using conventional content analysis. Resulting themes: circumstances of the death, burial events, thinking about and talking to the deceased sibling, fears, and life changes. Most children knew their sibling’s cause of death, attended funeral/memorials, thought about and talked to their deceased sibling, reported changes in family and themselves over the 13 months. Fears (something happening to themselves, parents, other siblings—death, cancer, being snatched away) decreased from 7 to 13 months especially in 7-year to 9-year-olds. Seven-year to 9-year-olds reported the greatest change in themselves from 7 to 13 months. More Black children and girls thought about the deceased and reported more changes in themselves over the 13 months. School aged children thought about and talked with their deceased sibling, reported changes in themselves and their family and their fears decreased over the first 13 months after their sibling’s death     

Similar minds in the family: COVID-19 centrality and relationship quality

We examined whether perceived similarity in COVID-19 centrality (i.e., the extent to which one thinks of the pandemic as shaping current and future life) is associated with family relationship quality during the pandemic. Thinking that other family members are similar to oneself regarding the pandemic's centrality may improve the quality of family relationships. We collected data from Turkish family triads (i.e., mother, father, 18–25 years old child) and had 481 participants from 180 families. Participants rated their similarity in COVID-19 centrality with the other two family members and reported the general and daily quality of their relationship with them (relationship satisfaction, closeness, conflict). We analyzed the data using the Social Relations Model. We found that family members who, on average, perceived more similarity in COVID-19 centrality reported higher levels in positive attributes of general relationship quality (i.e., satisfaction and closeness). The effects on conflict and daily relationship quality were less conclusive. This research confirms that family members' reactions during the COVID-19 pandemic are interdependent. Perceiving that other family members are of similar minds about the centrality of the pandemic relates positively to some aspects of relationship quality.     

Relationship Quality as a Moderator of Anxiety in Siblings of Children Diagnosed with Autism Spectrum Disorders or Down Syndrome

The purpose of this study was to examine typically-developing adolescents’ perceived relationship quality with their developmentally-disabled sibling, specifically siblings diagnosed with an autism spectrum disorder (ASD) or Down syndrome (DS). The 119 eleven through seventeen-year-old adolescent participants (M = 13.32, SD = 1.90) completed an online survey that assessed demographics, sibling relationship quality, and anxiety. Results showed that siblings of children with DS have a greater overall sibling relationship quality than do siblings of children with an ASD. Results further indicated that reporting more negative interchanges within the sibling relationship was related to higher levels of anxiety regardless of sibling disability type. Lastly, sibling relationship quality moderated the relation between sibling disability type and anxiety. These findings promote greater understanding of the sibling dynamic in families with children with developmental disabilities and suggest the need for establishing more research and greater clinical evaluation in this area. Furthermore, the current study suggests that therapeutic intervention to address the sibling relationship quality within children diagnosed with ASDs and their typically-developing siblings would be beneficial in order to increase social support within the relationship as well as decrease the amount of negative interchanges within the sibling relationship. Results also suggested that decreasing the amount of negative interchanges within the sibling relationship may decrease the level of anxiety the typically-developing sibling reports.     

Differential perceptions of and feelings about sibling children: implications for research on parenting stress

Parenting stress is influenced by parents' perceptions of their relationships with their children, which can vary widely for each parent depending on which child in the family is being considered. Because this within‐parent variation is rarely studied, we investigated some of the differential perceptions that arise with respect to children's behaviour problems and parent–child negativity/positivity. Participants included a national sample of adoptive parents of 486 pairs of genetically unrelated siblings. Mothers reported different perceptions of their sibling children, and within the family, the child who was rated higher in behaviour problems also was regarded with more negativity and less positivity. Furthermore, the magnitude of the difference was uncorrelated with various indicators of the family and home environment, including parental education and occupational prestige, type of housing and crowding in the home, and progressive versus traditional childrearing attitudes. This pattern of results was consistent with three previously published sibling studies utilizing similar methods. The results point to the importance of examining child effects and within‐parent differences in subjective aspects of the parenting experience. Copyright © 2005 John Wiley & Sons, Ltd.     

Siblings in dyads: relationships among perceptions and behavior

The ways in which middle-childhood siblings perceive themselves as similar or different was assessed with a sample of 40 pairs of 9- to 11-year-old (younger) and 12- to 14-year-old (older) siblings. Each child was interviewed and completed a card sort procedure and a measure of self-competence. Sibling pairs participated in three behavioral tasks coded for cooperation and conflict. Self-ratings, self-perceptions, and sibling behavior were analyzed for their association with the perceived similarity construct. Siblings perceived themselves as being more like one another than did their mothers. Forty-one percent of the variance in their perceived similarity was accounted for by paired self-cooperation ratings, social competence, and behavioral task scores.     

Differential experiences of siblings in the same family as predictors of adolescent sibling personality differences

In the area of personality development, environmental influences operate to make siblings in the same family different rather than similar to each other. The goal of the present study was to determine whether differential experience of siblings can be used to explain the marked personality differences of siblings. The Sibling Inventory of Differential Experience (SIDE) along with personality information (the EAS Temperament Inventory and questions about career expectations) was administered to 50 biological sibling pairs and 98 adoptive sibling pairs in adolescence and young adulthood. The results indicated that differential sibling interaction and differential peer characteristics as self-reported on the SIDE explain 6%-26% of the variance in sibling personality difference scores. For example, the sibling who reports more sociability as compared to his sibling also experiences more sibling closeness and more peer popularity as compared to his sibling. Comparison between adoptive and biological siblings indicates that the SIDE relations are mediated environmentally rather than genetically.     

Social comparisons with siblings made by adolescents with a learning difficulty

Social comparisons and the family environment are important antecedents of self-esteem. In this study the self-esteem and perceptions of stigma of 50 adolescents with a mild-moderate learning difficulty were measured. The self-esteem and stigma scores were factor-analysed to produce five factors: Positive self; Social competence; Being different; Anxiety; and Work competence. Social comparisons made by the adolescents between themselves and their siblings were also measured. Most adolescents 'preferred' (chose more often and gave high scores to) older same-sex siblings while younger opposite-sex siblings were the least preferred (were chosen less often and derogated). An explanation for these findings is suggested in terms of defensive social comparisons due to the loss of self-esteem in having a younger sibling ‘overtake’ the adolescent on developmental milestones, and in the tendency for non-handicapped pre-pubescent children to derogate the opposite sex during gender identity formation. This explanation is supported by the finding that the adolescents with younger siblings scored higher on the Anxiety factor than those who compared themselves with older siblings. Those with younger same-sex siblings were the most anxious. There was also a tendency for adolescents with siblings to score lower on one of the factors than adolescents with no sibling. The discussion raises the questions of how to deal with social comparisons within the family and how to talk to the child with mild learning difficulties about his or her handicap.     

When feeling bad makes you look good: guilt, shame, and person perception

In two studies, we examined how expressions of guilt and shame affected person perception. In the first study, participants read an autobiographical vignette in which the writer did something wrong and reported feeling either guilt, shame, or no emotion. The participants then rated the writer's motivations, beliefs, and traits, as well as their own feelings toward the writer. The person expressing feelings of guilt or shame was perceived more positively on a number of attributes, including moral motivation and social attunement, than the person who reported feeling no emotion. In the second study, the writer of the vignette reported experiencing (or not experiencing) cognitive and motivational aspects of guilt or shame. Expressing a desire to apologise (guilt) or feelings of worthlessness (private shame) resulted in more positive impressions than did reputational concerns (public shame) or a lack of any of these feelings. Our results indicate that verbal expressions of moral emotions such as guilt and shame influence perception of moral character as well as likeability.     

Longitudinal associations between parents' hostility and siblings' externalizing behavior in the context of marital discord.

This study examined longitudinal associations between parents' hostility and siblings' externalizing behavior in the context of interparental discord. The sample included 116 families (mothers, fathers, 2 siblings) assessed in middle childhood, when siblings were, on average, 8 and 10 years old, and in adolescence, at average ages of 14 and 16 years. Parents reported on their hostility toward each child and on each child's externalizing problems. Raters observed interparental hostility, and parents rated their marital quality. Results indicated both within-family and between-families effects. Specifically, the child who received more parental hostility than his or her sibling showed greater increases in externalizing problems than his or her sibling; this association was moderated by marital discord. In addition, the child who exhibited more behavioral problems than his or her sibling received greater increases in hostile mothering than did his or her sibling. Between-families effects were evident, in that children's externalizing problems were associated with increases in mothers' hostility toward both children in the family. Results support transactional models of development and family systems theory.     

The role of family in adolescents' peer acceptance

The study examined the relative importance of the quality of relationships with parents and grandparents, maternal acceptance and control, the structure of the family, the number of siblings, and adolescents' own attachment style to their perceived peer acceptance. The sample consisted of 300 adolescents (mean age = 15.5) and 300 mothers (mean age = 41.5). Regarding the role of family relationships, the results indicated that only the quality of the mother–child relationship was related to adolescents' peer acceptance. Maternal acceptance and control, however, were unrelated to youth's perceptions of acceptance by peers. Adolescents who had more siblings, lived in a single‐mother family, and were high in anxious attachment reported lower peer acceptance.     

Differential parenting and sibling jealousy: Developmental correlates of young adults’ romantic relationships

Data from a survey of 200 young adults assessed whether the early nonshared environment, specifically parental differential treatment, was associated with romantic relationship distress through its effects on sibling jealousy, attachment styles, and self‐esteem. Individuals who received equal affection from their parents in comparison to their sibling reported equal jealousy between themselves and their sibling, had higher self‐esteem, more secure attachment styles, and less romantic relationship distress. Receiving differential parental affection, regardless of whether the participant or their sibling was favored, was associated with more negative models of self and others, which in turn were associated with greater romantic relationship distress. Results indicate that early within‐family experiences may be particularly relevant for later healthy romantic relationship functioning.     

Brothers and Sisters: Nature and Importance of the Adult Bond

The closeness, importance and nature of adult sibling relationships were examined in a preliminary study. Forty-eight males and 87 females aged 17 to 84 years were subjects. Each completed a questionnaire about themselves and relationships with their siblings. Results indicated that females were closer to their siblings than were males, same-sex sibling pairs were closer than cross-sex pairs, and younger subjects were closer to their siblings than were older subjects. The nature of the relationship between siblings was very positive with few negative feelings reported. Sex, sexual makeup of the sibling pair, and age also affected the nature of the relationship and topics discussed between siblings.     

Mother-Child Relationship in Youths with Attention-Deficit Hyperactivity Disorder and their Siblings

Despite impaired mother-child interactions noted in youth with attention-deficit/hyperactivity disorder (ADHD), there is no such information for their siblings. This study aimed to test whether the affected and unaffected siblings, like youth with ADHD, also encountered impaired mothering and mother-child relationships as compared to typically developing youth (TD). The sample consisted of 122 probands (107 males, 87.7 %), aged 10–16, with DSM-IV ADHD, 44 affected (26 males, 59.1 %) and 78 unaffected (28 males, 35.9 %) siblings, and 122 TD youth. Both participants and their mothers received psychiatric interviews (K-SADS-E) about the participants and reported maternal parenting style, mother-child interactions and child behavioral problems at home. Based on both reports, probands with ADHD and affected siblings (only youth report) had more impaired relationships, more behavioral problems at home, and less perceived family support than unaffected siblings and TD youth. Probands with ADHD had higher maternal authoritarian control than unaffected siblings. The findings suggest that impaired mothering, mother-child interactions, and family support are related to the presence of ADHD diagnosis in both probands and their affected siblings.     

The Forgotten Ones: Siblings of Substance Abusers

Although factors shaping sibling relationships and the developmental dynamics of such consanguinity have been addressed by various scholars, investigations questioning how the risky behaviors of one sibling, specifically substance abuse, may impact brothers versus sisters are few. The current study explored non–substance-abusing siblings’ reports of their mood, attitudes, feelings of social support, and emotions if one of their brothers or sisters was perceived to be a substance abuser. Surprisingly, 22% of a college-aged convenience sample (N = 312) described one or more of their siblings as a substance abuser and reported being exposed to drugs at an earlier age than their non–substance-abusing counterparts, in addition to other differences. Sisters, more than brothers, were also affected. These exploratory findings, although limited by potential sampling bias, highlight potential areas for future research that could clarify and perhaps improve the experience of the “forgotten” siblings in a risky family constellation.     

Implicit orientation toward family and school among bilingual Latino college students

The authors examined the associations that underlie the orientations of bilingual Latino college students toward family and school. Participants completed, in English or Spanish, 3 implicit association tests assessing their attitude toward family vs. school, identifications with these concepts, and self-esteem. Results revealed a more positive attitude toward, and stronger identification with, family than school. Identification with family was stronger among participants who completed the study in English, suggesting self-definition in terms of distinctions from the context. Last, the more participants valued family over school and identified with family rather than school, the higher was their self-esteem. These findings shed light on the subtle, yet crucial, mechanisms by which cultural knowledge is incorporated in the self-concept of bilingual Latino college students.     

Risk perceptions and participation in colorectal cancer screening

Compared individuals at high versus average risk for colorectal cancer (CRC) with respect to factors they cited as affecting their risk of developing CRC. We also examined the relationship of these risk-factor perceptions to perceived susceptibility and participation in a CRC screening test. All individuals in the high-risk group were informed that, as a sibling of someone with CRC, they were more likely to get this cancer themselves. We found minimal differences among siblings with respect to perceived susceptibility. Further, although high-risk siblings were more likely to participate in screening, only 20.2% cited heredity as a risk-increasing factor, and, among these siblings, there was no relationship between screening participation and the citation of any specific risk factors, including heredity. These findings demonstrate the need for more research examining how high-risk individuals process risk-relevant information and the effect of this information on health behavior.     

Differences in Nonshared Individual,School, and Family Variables Between Delinquent and Nondelinquent Hmong Adolescents

The purpose of the current study was to determine whether there were differences between Hmong immigrant siblings on multiple nonshared individual, school, and family variables. Participants were 58 sibling pairs (29 delinquent pairs and 29 nondelinquent pairs), who ranged in age from 13 to 21 years. There were 11 pairs of boys, 3 pairs of girls, and 15 pairs of opposite-sex siblings. Results of a multivariate analysis of variance indicated that delinquent and nondelinquent sibling groups were significantly different in participation in organized activities, antisocial attitudes, delinquent behaviors, school truancy, school performance, and parents' labeling. The findings have implications for future research on sibling delinquency in Hmong immigrant families and for program development and delivery.
