Perceived parental rearing of bipolar offspring.

OBJECTIVE: To explore the impact of growing up with a parent with a bipolar disorder. First, we compared parental rearing behavior perceived by young adult offspring of bipolar parents with parental rearing behavior perceived by same aged young adults from the general population. Secondly, we examined the associations between perceived parental rearing behavior and parental psychopathology and psychopathology in offspring. METHOD: Subjects were 129 offspring of 80 bipolar parents and their spouses and 1122 young adults from the general population. In offspring the Structured Clinical Interview for DSM-IV was used to assess DSM-IV diagnoses and the EMBU was used to assess perceived parental rearing in both groups. RESULTS: In general, offspring growing up in a family with a bipolar parent perceived their mothers as less rejecting, more emotionally warm and less overprotecting and their fathers as less emotionally warm and less overprotecting compared with young adults from the general population. Perceived rejection was related to psychopathology in offspring. CONCLUSION: Overall, parental rearing in families with a parent with a bipolar disorder is not more dysfunctional, as perceived by their offspring, than in families from the general population. Offspring with a bipolar disorder perceive their parents as more rejecting.

Measuring quality of life in children referred for psychiatric problems: psychometric properties of the PedsQL 4.0 generic core scales.

OBJECTIVE: The aim of this study was to assess the psychometric properties of the Dutch translation of the Pediatric Quality of Life Inventory (PedsQL 4.0) generic core scales and assess its usefulness in measuring quality of life (QoL) in a child psychiatric population. METHODS: Reliability and validity of the PedsQL were assessed in 310 referred children (ages 6-18 years) and a comparison group consisting of 74 non-referred children (ages 7-18 years), and the parents in both groups. RESULTS: Confirmatory factor analysis resulted in a four-factor solution. Internal consistency reliability for the PedsQL Total Scale Score (alpha = 0.84 child self-report, alpha = 0.87 parent proxy-report), Psychosocial Health Score (alpha = 0.70 child self-report, alpha = 0.81 parent proxy-report), and most subscale scores were acceptable for group comparisons. Correlations between scores of fathers and mothers were large. Criterion-related validity was demonstrated by significantly lower PedsQL scores for referred vs. non-referred children. Significant correlations between PedsQL scales and measures of psychopathology showed convergent validity. Small correlations between PedsQL scales and intelligence of the child evidenced discriminant validity. CONCLUSION: The PedsQL seems a valid instrument in measuring QoL in children referred for psychiatric problems.

Preschool developmental pathways to preadolescent internalizing and externalizing problems.

The present study investigated longitudinal pathways from specific early preschool behavioral problems (ages 2-3 years) to internalizing and externalizing problems in preadolescence (ages 10-11 years), and the role of social problems at school entry (ages 4-5 years) in such pathways. Path analyses were performed using both parent and teacher reports in a sample of 251 to 346 children from the general population, depending on the availability of parent and teacher data at each time of assessment. Structural equation modeling revealed homotypic internalizing and externalizing pathways, predictions from early preschool externalizing problems to later internalizing problems, and negative predictive paths from early internalizing problems to externalizing problems in preadolescence. Cross-informant predictions spanning 8 years were found between parent-reported aggression and overactivity at ages 2-3 years and teacher-reported externalizing problems at ages 10-11 years. Further, results showed that boys' pathways were more complex and showed greater predictive validity than pathways for girls, and that social problems at school entry played a significant role in pathways to internalizing problems, but only for boys. The results are discussed from a developmental psychopathology perspective.

Zygosity diagnosis in young twins by parental report.

This study reports on zygosity determination in twins of childhood age. Parents responded to questionnaire items dealing with twin similarity in physical characteristics and frequency of mistaking one twin for another by parents, relatives and strangers. The accuracy of zygosity diagnosis was evaluated across twins aged 6, 8, and 10 and across parents. In addition, it was examined whether the use of multiple raters and the use of longitudinal data lead to an improvement of zygosity assignment. Complete data on zygosity questions and on genetic markers or blood profiles were available for 618 twin pairs at the age of 6 years. The method used was predictive discriminant analyses. Agreement between zygosity assigned by the replies to the questions and zygosity determined by DNA markers/blood typing was around 93%. The accuracy of assignment remained constant across age and parents. Analyses of data provided by both parents and collected over multiple ages did not result in better prediction of zygosity. Details on the discriminant function are provided.
