[Parental support, parental self-efficacy and borderline personality features in adolescents]. / Ouderlijke steun, opvoedvertrouwen en borderlinekenmerken bij adolescenten.

BACKGROUND: Parenting an adolescent with borderline personality disorder (BPD) features can be challenging due to, for example, emotional dysregulation, impulsivity and/or self-destructive behavior. Parents confronted with challenging behavior of their child, may experience less parental-self-efficacy (PSE). Subsequently this lower PSE might strengthen the relationship between low parental support and BPD features. AIM: To increase our understanding of the association between parenting related factors and features of BPD in adolescents. METHOD: The sample consisted of 81 adolescents, in the age of 13-21, from a clinical population and their parents. Parents completed (online) questionnaires on parental self-efficacy and adolescents reported on parental support and BPD features. RESULTS: Adolescents who experienced lower parental support reported more BPD features. Lower parental self-efficacy was not related to BPD features in adolescence, but (more) self-efficacy was related to (older) age. Subsequently no evidence was found for a combined effect of perceived parental support and parental self-efficacy on adolescent BPD features. CONCLUSION: Adolescents in a clinical population with higher levels of BPD perceived lower levels of parental support. Parental self-efficacy was not related to levels of BPD. This research is a first step in understanding parenting related factors and BPD features. Longitudinal research is needed to gain more insight in transactions between parenting related factors and symptoms of adolescent BPD.

[Borderline personality pathology in young people: complexities in understanding of and relating to others]. / Problemen in het begrijpen van en omgaan met anderen; relaties tussen borderlinepersoonlijkheidsproblemen en psychosociaal functioneren bij adolescenten.

BACKGROUND For a long time there was controversy and reservations with regards to diagnosing borderline personality disorder (BPD) under the age of eighteen. Progress in scientific knowledge has shown that adolescence is a key phase in the understanding of the development of the disorder.
AIM: To contribute to the understanding of the developmental trajectory of BPD by studying associations between BPD and the interpersonal functioning in adolescence.
METHOD: To study associations between personality, cluster B personality pathology and BPD and associations between BPD and interpersonal functioning, specified in social information processing and relationship quality with parents and peers.
RESULTS: Personality dimensions and social information processing, both independently and together, are related to cluster B personality pathology and BPD. Furthermore, the importance of quality of relationships with parents in relation to BPD is confirmed..
CONCLUSION: The role of social environment is complex in the development of BPD. The results underpin the interpersonal nature of BPD in adolescence as a crucial phase within the psychosocial development.

Impulse control and aggressive response generation as predictors of aggressive behaviour in children with mild intellectual disabilities and borderline intelligence.

BACKGROUND: A growing interest exists in mechanisms involved in behaviour problems in children with mild intellectual disabilities and borderline intelligence (MID/BI). Social problem solving difficulties have been found to be an explanatory mechanism for aggressive behaviour in these children. However, recently a discrepancy was found between automatic and reflective responding in social situations. We hypothesise that low impulse control and aggressive social problem solving strategies together may explain mechanisms involved in aggressive behaviour by children with MID/BI. METHOD: In a clinical sample of 130 children with MID/BI receiving intramural treatment, main, moderating and mediating effects of impulse control and aggressive response generation on aggressive behaviour were examined by conducting hierarchical linear multiple regression analyses. RESULTS: Independent main effects of both impulse control and aggressive response generation on aggressive behaviour were found. Results indicated that low impulse control and aggressive response generation each explain unique variance in aggressive behaviour. CONCLUSIONS: As this study is the first that has shown both impulse control and aggressive response generation to be important predictors for aggressive behaviour in children with MID/BI, future research should further examine the nature of relations between low impulse control and social problem solving.

The longitudinal relations between parenting and toddlers' attention problems and aggressive behaviors.

The aim of the present study was to examine the normative developmental trajectories of toddlers' externalizing behaviors and several maternal and paternal parenting dimensions. Latent growth models were used to determine intraindividual changes and interindividual differences in these changes. One hundred and eight boys were followed from 17 months of age to 35 months of age. A significant linear decrease in attention problems and a significant linear increase in aggressive behaviors were found. Additionally, multivariate models were tested that related the developmental trajectories of externalizing behaviors to the trajectories of the parenting dimensions. The results showed meaningful contemporary relations and relations between over-time trajectories of parenting dimensions and children's externalizing behaviors.

Differential family and peer environmental factors are related to severity and comorbidity in children with ADHD.

Behavioral genetic studies imply that salient environmental influences operate within families, making siblings in a family different rather than similar. This study is the first one to examine differential sibling experiences (as measured with the Sibling Inventory of Differential Experience) and its effect on behavioral outcomes within ADHD families. Subjects were 45 Dutch ADHD probands and their unaffected siblings (n = 45) aged 10-18 years. ADHD probands and their unaffected siblings reported differences in sibling interaction, parental treatment, and peer characteristics. These nonshared environmental influences were related to both the severity of ADHD symptoms as well as to comorbid problem behaviors. These findings suggest that environmental influences that operate within ADHD families appear relevant to the severity of problem behaviors of ADHD children and their siblings.

Externalizing behaviors and minor unintentional injuries in toddlers: common risk factors?

OBJECTIVE: To investigate predictors for externalizing behaviors and minor unintentional injuries in toddlers and to examine whether common risk factors can be identified. METHODS: Linear regression models were used to investigate the contributions of predictors belonging to the domains of child characteristics and parental characteristics. Participants were 117 boys (M = 16.9 months) and their parents. RESULTS: Two common risk factors for externalizing behaviors and minor injuries were identified: maternal low conscientiousness and paternal low self-control. In addition, children's inhibitory control and dispositional frustration as well as maternal externalizing symptoms contributed independently to children's externalizing behaviors. CONCLUSIONS: Results supply some evidence for the interrelatedness of negative outcomes and on the existence of common risk factors. Interventions could aim to address these common risk factors in order to pursue a number of goals at the same time, instead of focusing on only one type of negative outcome.
