ABSTRACT In the current meta-analysis, we investigated the link between child and adolescent sibling relationship quality (warmth, conflict and differential treatment) and internalizing and externalizing problems, and potential moderators of these associations. From 34 studies, we obtained 85 effect sizes, based on 12,257 children and adolescents. Results showed that more sibling warmth, less sibling conflict and less differential treatment were all significantly associated with less internalizing and externalizing problems. Effect sizes for sibling conflict were stronger than for sibling warmth and differential treatment, and associations for internalizing and externalizing problems were similar in strength. Effect sizes were moderated by sibling gender combination (stronger effects for higher percentage brother pairs), age difference between siblings (stronger effects for smaller age differences), and developmental period (stronger effect sizes for children than for adolescents). These results indicate that the sibling context is important when considering psychopathology. In addition to the overwhelming evidence of the impact of parent-child and marital relationships on child and adolescent development, the present meta-analysis is a reminder that the sibling relationship warrants more attention in research as well as in clinical settings.

    ABSTRACT: Being the victim of peer bullying is associated with increased risk of psychopathology, yet it is not known whether similar experiences of bullying increase risk of psychiatric disorder when the perpetrator is a sibling. We tested whether being bullied by a sibling is prospectively associated with depression, anxiety, and self-harm in early adulthood.

    ABSTRACT: The sibling relationship and its potential impact on neurodevelopment and mental health are important areas of neuroscientific research. Validation of the tools assessing the quality of the sibling relationship would be the first essential step for conducting neurobiological and psychosocial studies related to the sibling relationship. However, to the best of our knowledge, no sibling relationship assessment tools have been empirically validated in Korean. We aimed to evaluate the psychometric properties of the Korean version of the Lifespan Sibling Relationship Scale (LSRS), which is one of the most commonly used self-report questionnaires to assess the quality of the sibling relationship. A total of 109 adults completed a series of self-report questionnaires including the LSRS, the mental health subscale of the Medical Outcomes Study-Short Form 36 version 2 (SF36v2), the Satisfaction with Life Scale (SLS), and the Marlowe-Crowne Social Desirability Scale (MC-SDS). The internal consistency, subscale intercorrelations, one-week test-retest reliability, convergent validity, divergent validity, and the construct validity were assessed. All six subscale scores and the total score of the LSRS demonstrated good internal consistency (Cronbach's α=0.85-0.94) and good test-retest reliability (intraclass correlation coefficient=0.77-0.92). Correlations of the LSRS with the SF36v2 mental health score (r=0.32, p=0.01) and with the SLS (r=0.27, p=0.04) supported the good convergent validity. The divergent validity was shown by the non-significant correlation of the LSRS with the MC-SDS (r=0.15, p=0.26). Two factors were extracted through factor analysis, which explained 78.63% of the total variance. The three Adult subscales loaded on the first factor and the three Child subscales loaded on the second factor. Results suggest that the Korean version of the LSRS is a reliable and valid tool for examining the sibling relationship.

    ABSTRACT: OBJECTIVES: The aims of this study were the following: to identify perceptions of patients with anorexia nervosa (AN) and their siblings regarding differential experiences within and external to the family including sibling interactions, parental treatment, relationships with peers and events that are unique to each sibling; (2) to compare how patients and their siblings perceive eating disorder symptoms, parental affection/control, social support and stigma; and (3) to test associations with family functioning for patients with AN and their siblings. METHOD: A total of 26 patients paired with their siblings were recruited from an Eating Disorder Program and administered standardized instruments measuring different experiences within and external to the family, the impact of eating disorder behaviours, stigma, social support and family functioning. RESULTS: Patients rated high on the differential experience of jealousy in contrast to their siblings. Patients scored higher than their siblings on eating symptoms, whereas siblings scored higher on social support. The impact of AN on the family, stigma towards the individual and family, and social support accounted for 37% of the variance in family functioning from the sibling perspective after controlling for age and gender. Of these variables, impact of AN on the family made the largest contribution. DISCUSSION: Family-based and sibling-based interventions that aim to reduce the effects of the illness on the sibling relationship and the family are recommended.
