Stability and Changes in Problem Behavior during Adolescence: Latent Growth Analysis.

The aim of this study was to examine growth trajectories of externalizing and internalizing problems during adolescence. In addition, we also examined factors that might account for individual differences in the level of problem behavior and in the rate of change: Adolescent gender and the quality of the relationships with parents and peers. The sample consisted of 212 adolescents (mean age 13.4 years at the initial assessment) who were assessed at 3 measurement waves with approximately 1-year intervals. The results showed substantial absolute and relative stability in both types of problem behavior, but also significant individual differences in both initial levels of problem behavior and in the rate of change across the 3 measurement occasions. Adolescent gender and the quality of the parent–adolescent relationship predicted the initial level of both externalizing and internalizing problems. The protective effect of the positive quality of the relationship with peers was found for internalizing but not for externalizing problems. No differences appeared between boys and girls in the effect of the quality of interpersonal relations on the level and on the rate of change in problem behavior, suggesting that the etiology of problem behavior might be similar for boys and girls in spite of gender differences in the prevalence of problem behaviors.

Developmental Patterns in Adolescent Attachment to Mother, Father and Sibling

The aim of this study was to examine the development of quality of attachment of adolescents to their parents and siblings during adolescence and the role that gender differences play in this development, using latent growth curve analysis. In 288 families, adolescents reported on their attachment relationships with their parents and siblings. Quality of attachment changes during adolescence, and these changes are influenced by both gender of the adolescent and gender of the attachment figure. Results showed that change in mean level of quality of attachment to mother appeared to be nonlinear for boys, whereas mean level of attachment of adolescent girls to their mothers showed a linear decline. Results for attachment to father were opposite, with a linear decline in quality for boys, and a nonlinear development for girls. Quality of attachment to sibling showed differential development depending on gender composition of the sibling dyad.

Sibling relationship quality and psychopathology of children and adolescents: A meta-analysis

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.

Attachment in adolescence: A social relations model analysis

A fundamental question in the study of attachment is the explanation for differences in quality of attachment. In the present study, the Social Relations Model (SRM) was used to examine whether these differences in quality of attachment could be explained by (a) characteristics of the person (actor effect), (b) characteristics of the attachment figure (partner effect), (c) characteristics of the specific attachment relationship (relationship effect), or (d) characteristics of the family (family effect). In 288 families, two adolescent children and their parents reported on their attachment relationships with other family members. Results of SRM analyses showed that, in general, characteristics of the person reporting the attachment relationship and characteristics of the attachment relationship are the most important explanations for differences in quality of attachment, but the magnitudeof these effects tendsto vary depending on which family relationshipis considered.

Multiple Perspectives Within the Family Family Relationship Patterns

The first aim of the present study was to examine the extent to which the larger network of family relationships (parent-adolescent, marital, and sibling relations) affect adolescent adjustment. The second aim was to identify distinct patterns of family relationships and to examine whether these different family relationship patterns are associated with adolescent adjustment. The sample consisted of 288 intact families with two adolescent siblings. Each family member provided information on the affective quality of his or her relationship with every other family member (round-robin design). The quality of all family relations was related to the indicators of deviant development (problem behavior) but not to the indicators of normative development (identity formation). Five distinct and theoretically consistent clusters of different constellations of affective family relations were found. Differences in adolescent problem behavior were related to the cluster membership. The usefulness of the family systems perspective for research on adolescent development is discussed.

Sibling relationship quality and adolescent delinquency: a latent growth curve approach.

The present study examined whether level and changes in sibling relationship quality and older sibling delinquency are related to level and changes in younger sibling delinquency, for brother, sister, older brother/younger sister and older sister/younger brother sibling pairs. Questionnaire data were collected from 249 Dutch sibling pairs (11-15 years old) over a period of three years, with annual measurements. Results showed that level and over-time changes in sibling relationship quality and older and younger sibling delinquency were significantly different for the four sibling gender combinations. Results of multivariate growth curve modeling showed that sibling relationship quality was related to delinquency of older siblings (but not younger siblings), and delinquency of older siblings was associated with younger sibling delinquency two years later. We also found differences between the four sibling gender combinations. For example, for brother and sister pairs (but not mixed-sex sibling pairs), over-time changes in older sibling delinquency were related to younger sibling delinquency two years later as well as the change pattern in younger sibling delinquency over time. Strengths, limitations and possible implications for research and intervention of adolescent delinquency are discussed.

Sibling relationship patterns and their associations with child competence and problem behavior.

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.

Attachment stability and change during adolescence: A longitudinal application of the Social Relations Model

An important issue in attachment theory and research is explaining individual differences in attachment quality. In this study, we examined (i) the relative importance of individual, dyadic, and family characteristics in explaining attachment quality differences and (ii) changes in the importance of these characteristics during adolescence. We examined these questions by applying the Social Relations Model to two-wave longitudinal data. Two parents and two adolescents from 210 families reported their attachment relationships with other family members. Results showed that differences in quality of attachment are best explained by the adolescents internal working model (individual) and by relationship-specific (dyadic) characteristics. We found few longitudinal changes, indicating stability in these attachment processes. Implications of these results and important directions for future research are discussed.

Siblings versus Parents and Friends: Longitudinal Linkages to Adolescent Externalizing Problems.

Background: It is well documented that friends’ externalizing problems and negative parent–child interactions predict externalizing problems in adolescence, but relatively little is known about the role of siblings. This four-wave, multi-informant study investigated linkages of siblings’ externalizing problems and sibling–adolescent negative interactions on adolescents’ externalizing problems, while examining and controlling for similar linkages with friends and parents. Methods: Questionnaire data on externalizing problems and negative interactions were annually collected from 497 Dutch adolescents (M = 13.03 years, SD = 0.52, at baseline), as well as their siblings, mothers, fathers, and friends. Results: Cross-lagged panel analyses revealed modest unique longitudinal paths from sibling externalizing problems to adolescent externalizing problems, for male and female adolescents, and for same-sex and mixed-sex sibling dyads, but only from older to younger siblings. Moreover, these paths were above and beyond significant paths from mother–adolescent negative interaction and friend externalizing problems to adolescent externalizing problems, 1 year later. No cross-lagged paths existed between sibling–adolescent negative interaction and adolescent externalizing problems. Conclusions: Taken together, it appears that especially older sibling externalizing problems may be a unique social risk factor for adolescent externalizing problems, equal in strength to significant parents’ and friends’ risk factors.

Factors associated with traumatic symptoms and internalizing problems among adolescents who experienced a traumatic event

Abstract The aim of the present study was to identify factors that are related to the traumatic symptoms and problem behavior among adolescents who experienced the New Years fire in 2001 in Volendam, The Netherlands. Three groups of factors were considered: pre-trauma (personality and coping), trauma-related (physical and emotional proximity to disaster), and post-trauma factors (received social support). Forty-five adolescents completed the questionnaire. Two years after the disaster, these adolescents experienced significant traumatic stress reaction (70% within the clinical range) and showed clinically significant levels of internalizing problems (37%). Pre-trauma, individual factors were identified as the most important predictors of distress, followed by received social support. The indicators of physical and emotional proximity to disaster explained little variance in distress.
