Four-year follow-up of an epidemiological sample.

In this 4-year follow-up of behavioral/emotional problems in an epidemiological sample of 1,200 children originally aged 4 to 12 years assessed with the Achenbach Child Behavior Checklist (CBCL), high stability in the level of CBCL total problem scores was found. Stability of problem behavior was equally substantial for ages 4 to 12 and both sexes. Aggressive and other externalizing behaviors showed the highest stability. Even in children as young as 4 to 5 years, aggressive and attentional problems showed considerable stability. The results of the present study were informative with respect to methodology in indicating clearly that employing a mailing survey for obtaining parent reports on behavioral/emotional problems resulted in the selective exclusion of a group of especially problematic children who were recovered when parents were interviewed at home.

Major life events and changes in the behavioural functioning of children.

The relationship between major life events and changes, across a 2-yr period, in the level of parent-reported behavioural/emotional problems in 1397 children from a general population sample was investigated using a highly modified version of the Coddington Life Events Record and the Achenbach Child Behavior Checklist. The life event questionnaire used in the present study proved to have a satisfactory reliability. The number of life events increased significantly with increasing age of the child, and a higher incidence of such events was found for families with lower socio-economic status. A significant relationship was found between the total score of negative life events across the 2-yr period and changes in the level of behavioural/emotional problems of the children.

[Psychosocial aspects of the so-called short-bowel syndrome in children].

In a retrospective study of 16 patients with (congenital) bowel pathology, aged 2 to 12, attention was paid to the psychosocial aspects of the short bowel syndrome. Parents were interviewed and parents' and teachers' reports of children's behavioural and emotional problems were obtained. Parents as well as children appeared to have reached a reasonable level of adjustment. Parents' emotions concerning the period of hospitalisation still appeared to be strikingly strong. Although most children did not show obvious psychopathology, problems were observed in the areas of behaviour and attention, interfering with optimal school functioning in the case of some children.

Replication of empirically derived syndromes as a basis for taxonomy of child/adolescent psychopathology.

To advance the empirical identification of child/adolescent syndromes, principal components analyses were performed on four sets of parents' ratings of 8,194 6- to 16-year-olds referred to American and Dutch mental health services. The following syndromes replicated well for both sexes at ages 6-16: Aggressive, Anxious/Depressed, Attention Problems, Delinquent, Somatic Complaints, and Withdrawn. For both age ranges, a syndrome designated as Socially Inept replicated well among boys, and one designated as Mean replicated well among girls. Evidence was also found for a Schizoid syndrome in all sex/age groups and a Sex Problems syndrome among girls at ages 6-11. Syndrome scores discriminated well between nationwide normative and clinical samples. The replicated syndromes contribute to the empirical basis for a taxonomy of the kinds of disorders commonly seen between the ages of 6 and 16.

Problems reported for clinically referred American and Dutch children.

Child Behavior Checklists completed by parents of 50 children of each sex at each age from 4 to 16 seen in 28 American and 21 Dutch mental health services (N = 2,600) were examined. Analyses controlling for sex, age, and socioeconomic status showed somewhat higher total problem scores for American than Dutch children, with a mean of 57.27 versus 53.18 on a scale ranging from 0 to 240. This nationality difference accounted for less than 1% of the variance in total scores. American children obtained higher scores on more externalizing items than Dutch children. Small but significant differences in total, externalizing, and internalizing problems found between the two samples may reflect nationality differences in referral patterns. Competence scores were significantly higher for American than Dutch referred children, but did not differ as much as in comparable normative samples. Competence scores may reflect cultural differences more than problem scores do.

Agreement between parents' and teachers' ratings of behavioral/emotional problems of children aged 4-12.

Parents' and teachers' reports of behavioral/emotional problems in 1161 children aged 4-12 from the general population and assessed via the Achenbach Child Behavior Checklist were compared. Low to moderate agreement was found, with parents reporting more problems than teachers. Agreement was higher for externalizing problems than for internalizing problems and higher for children receiving special education than for those receiving regular education. Agreement was slightly higher for older than younger children. Sex of the child did not influence parent-teacher agreement. Teachers scored children higher on problems related to peer relations and on problems interfering with academic functioning, whereas parents scored their children higher on problems associated more strongly with externalizing than with internalizing syndromes.

Mental health in Dutch adolescents: self-reported competencies and problems for ages 11-18.

Beside parents and teachers, adolescents themselvess may be valuable informants about their own psychological functioning. The present study, which provides prevalence data on behavioral/emotional problems and competencies reported by adolescents aged 11-18 from the general population, was preceded by two studies providing such data for parent and teacher reported problems. The instrument used in the present study is the Youth Self Report (YSR) developed by Achenbach and Edelbrock to obtain adolescents' self-reports on their problems and competencies in a standardized way. YSRs completed by 52 adolescents on two occasions with a time-interval of 3-4 weeks revealed test-retest reliability expressed as intraclass correlation coefficients of 0.87 for total problem scores and 0.69 for total competence scores. The YSR was completed by 941 adolescents aged 11-18 from the general population. For each of the 103 problem items and 17 competence items, the prevalence rates were presented graphically for both genders in two-year age-groups. To identify differences related to sex, age and socio-economic status (SES), ANCOVAs were performed on the scores for each problem and competence item as well as on total problem and total competence scores. Whereas the level of problem scores was the same across the 11-18 years age-span, girls obtained higher total problem scores with increasing age. Younger girls scored lower and older girls scored somewhat higher than boys. Implications of these findings with respect to sex differences in referral rates for children and adults are discussed. The increase with increasing age in self-reports of problems concerning inner feelings and thoughts may reflect the adolescent's change in cognitive, socio-emotional and physical functioning. We could not demonstrate significant SES differences in problem scores. Comparisons of problem scores obtained for referred and nonreferred adolescents revealed a correct classification rate of 73.6%, which seems satisfactory given the fact that parents rather than the adolescent usually initiate referrals. Comparisons of problem item scores in ANCOVAs of referred and nonreferred samples revealed significant referral status effects for 68 of the 103 problem items, with referred adolescents scoring higher than nonreferred adolescents. The largest effect of referral status was found for the item "Nervous". The third largest effect was obtained for the item "Unhappy, sad, depressed", which also showed strong discrimination between parent scores for referred and nonreferred samples. Competence scores showed much weaker discrimination between referred and nonreferred groups.

Childhood depression: problems of definition.

The occurrence of depressive disorders in children is a problematic and confusing issue, and it is uncertain whether such behavior should be regarded as manifestations of depression so regarded in adults. Studies of childhood depression might benefit from approaches considering developmental differences in the patterning of depressive manifestations. Use of adult diagnostic criteria and premature disregard of developmental differences may impede accurate study and diagnoses of childhood depression. Empirical, multivariate approaches could be used to investigate symptom groupings to confirm existing diagnostic criteria, or stimulate adjustment of these criteria to identified developmental differences.

A comparison of syndromes derived from the child behavior checklist for American and Dutch girls aged 6-11 and 12-16.

Child Behavior Checklists completed by parents of 1848 clinically referred American and Dutch girls aged 6-11 and 12-16 were subjected to principal components analyses with varimax rotations. For the 6-11 yr age group, seven of the nine empirically derived syndromes showed cross-national correlations ranging from 0.80 to 0.98. For 12-16-yr-old girls, all eight of the American syndromes were firmly replicated for Dutch girls with correlations ranging from 0.84 to 0.97. Furthermore, cross-national similarities in the distribution of scores for normative samples supported the use of the same syndrome scales by clinicians and researchers in the two countries.

Persistence and change in behavioral/emotional problems reported by parents of children aged 4-14: an epidemiological study.

Crucial to our understanding of psychopathology in children is information on the stability and change of behavioral/emotional problems and competencies across time. Existing studies, reviewed in this article, provide only limited answers due to one or more of the following factors: restriction of the sample to a single locality, the use of selected samples, large sample attrition, the use of different assessment instruments at different times, the small number of specific behavioral/emotional problems or the use of very broad categories of functioning. The present study was designed to test the persistence and change of behavioral/emotional problems and competencies as reported by parents of 1,412 children aged 4-14 over a two-year period in a representative sample of the general population. At both points, standardized parents' reports were obtained using the Achenbach Child Behavior Checklist (CBCL). A recovery rate of 80.2% was obtained. Our study is the only one, as far as we known, to present follow-up data separately for ages covering the preschool period to adolescence, making it possible to compare stabilities in the occurence of behavioral/emotional problems across various developmental levels. Over the two-year follow-up period, there was a significant decrease in problem scores. Although possible, it is unlikely that the mental health of children in our sample increased very much. A decrease in problem scores over time has been demonstrated for clinical as well as general population samples in other studies as well. No satisfactory explanations are available for this phenomenon. It is important, however, that studies employing a retest design take account of this phenomenon. Irrespective of changes in the magnitude of group scores over time, stability coefficients can tell us whether individual children tend to preserve their rank orders. The stability coefficients between Time 1 and Time 2 total problem scores ranged from .62 (girls, aged 4-5) to .71 (boys, aged 6-11). No significant differences between stability coefficients for different age-groups and for both sexes could be demonstrated. The changes in scores across time for individual items were consistent with the cross-sectional data of our earlier study (Verhulst et al. Acta Psychiatrica Scandinavica, 1985, 72, suppl. 323). Stability coefficients for social competence scores at both times of assessment were generally somewhat weaker than those found for problem scores.(ABSTRACT TRUNCATED AT 400 WORDS)
