“…Both, however, will result in a difference in trait variance of MZ and DZ twins. Evidence for rater contrast/sibling interaction is found in some studies (for a review, see Garcia, Shaw, Winslow, & Yaggi, 2000).…”

“…For example, the current model assumes that the INT of one twin does not directly affect the other twin's INT. For common childhood psychopathology, claims of cooperation and competition effects have been made (for a review, see Garcia, Shaw, Winslow, & Yaggi, 2000). Sibling interactions may be very hard to distinguish from certain types of rater effects (Eaves et al, 2000;Neale & Stevenson, 1989;Simonoff et al, 1998).…”

Genetically informative data can be used to address fundamental questions concerning the measurement of behavior in children. The authors illustrate this with longitudinal multiplerater data on internalizing problems in twins. Valid information on the behavior of a child is obtained for behavior that multiple raters agree upon and for rater-specific perception of the child's behavior. Rater-disagreement variance 2 (rd) accounted for 35% of the individual differences in internalizing behavior. Up to 17% of this 2 (rd) was accounted for by rater-specific additive genetic variance 2 (A u ). Thus, the disagreement should not be considered only to be bias/error but also as representing the unique feature of the relationships between that parent and the child. The longitudinal extension of this model helps to make a distinction between measurement error and the raters' unique perception of the child's behavior. For internalizing behavior, the results show large stability across time, which is accounted for by common additive genetic and common shared environmental factors. Rater-specific shared environmental factors show substantial influence on stability. This could mean that rater bias may be persistent and affect longitudinal studies. Genetically informative designs can be used to estimate the size of genetic and environmental effects on variation in behavior and other complex traits. It is less well known that these designs also have the potential to shed a unique light on fundamental measurement problems and could be an important addition to the traditional methodological arsenal for studying psychological data. This is illustrated in this article by studying sources of rater (dis)agreement in longitudinal data on internalizing problems in monozygotic (MZ) and dizygotic (DZ) twins rated at ages 3, 7, 10, and 12 years by their parents. Rater (Dis)agreementSelf-and observer ratings of behavior are important sources of information in psychology and psychiatry. It is

“…Our work adds to the limited literature on sibling aggression generally characterized by small, nonrepresentative samples. 8,9 Our nationally representative study also removed the confounding influence of other kinds of victimization exposure and to assess the effects of multiple types of sibling aggression. Thus, we were able to show the damaging effects of several forms of sibling aggression, independent of other co-occurring victimizations.…”

“…6,7 Findings from the few small studies of sibling aggression, which are typically conducted with convenience samples and limited to the assessment of physical assault, also show its occurrence is linked with poorer mental health. 8,9 In the current study, using a national probability sample, we examined whether being a victim of sibling aggression is associated with children' s and adolescents' mental health. In doing so, we provide a comprehensive picture of the links between sibling aggression and mental health through our examination of 3 subtypes of sibling aggression: physical assault, property victimization, and psychological aggression by a sibling.…”

OBJECTIVE: Sibling aggression is common but often dismissed as benign. We examine whether being a victim of various forms of sibling aggression is associated with children’s and adolescents’ mental health distress. We also contrast the consequences of sibling versus peer aggression for children’s and adolescents’ mental health. METHODS: We analyzed a national probability sample (n = 3599) that included telephone interviews about past year victimizations conducted with youth aged 10 to 17 or an adult caregiver concerning children aged 0 to 9. RESULTS: Children ages 0 to 9 and youth ages 10 to 17 who experienced sibling aggression in the past year (ie, psychological, property, mild or severe physical assault), reported greater mental health distress. Children ages 0 to 9 showed greater mental health distress than did youth aged 10 to 17 in the case of mild physical assault, but they did not differ for the other types of sibling aggression. Comparison of sibling versus peer aggression generally showed that sibling and peer aggression independently and uniquely predicted worsened mental health. CONCLUSIONS: The possible importance of sibling aggression for children’s and adolescents’ mental health should not be dismissed. The mobilization to prevent and stop peer victimization and bullying should expand to encompass sibling aggression as well.

“…A common finding is that a warm sibling relationship is associated with positive behavioral adjustment (Modry-Mandell et al, 2007), while a conflicted relationship is associated with poor behavioral outcomes (Garcia et al, 2000). However, whether such associations hold for twin populations is unclear.…”

Do Twins Differ From Single-Born Children on Rates of Behavioral Difficulty in Early Childhood? A Study of Sibling Relationship Risk Factors

et al. 2014

The hypothesis that twinning raises risk for behavioral difficulties in childhood is persistent, yet there is limited and inconsistent empirical evidence. Simple mean comparison without control for confounders provides data on prevalence rates but cannot provide knowledge about risk or etiology. To assess the effect of twin relationship on behavior, comparison of patterns of association with single-born siblings may be informative. Analyses of data from an Australian sample of twins and single-born children (N = 305, mean age 4 years 9 months, and a follow-up 12 months later) were undertaken. The outcome measure was the Strengths and Difficulties Questionnaire. Predictor and control measures were obtained from parent report on the sibling/co-twin relationship behavior, family demographics, and obstetric history. We assessed difference between twins and single-born children in two respects: (a) mean behavioral difficulties, and (b) patterns of association between sibling relationship and behavioral difficulties, controlling for confounders. Results showed no differences in mean levels of behavioral difficulties between twins and single-born siblings identifying the importance of statistical control for family and obstetric adversity. Differences in patterns of association were found; for twin children, conflict in their co-twin relationship predicted externalizing behaviors, while for single-born children conflict predicted internalizing behaviors. The findings of mean differences between twin and single-born children in social background, but not in behavioral difficulties, underscore the necessity of statistical control to identify risk associated with twinning compared with risk associated with family and obstetric background factors.
