Evaluation of attention before and after 2 years of growth hormone treatment in intrauterine growth retarded children.

The objective of this study was to assess attention in children with short stature following intrauterine growth retardation (IUGR), at baseline and after 2 years of growth hormone (hGH) treatment. At baseline, all of the children had a birth height and a current height below the third centile. The attention measures (Sonneville Visual Attention Tasks: SVAT) of the IUGR group were compared with those of a comparison sample. In the baseline analyses, 48 children with IUGR and 119 comparison children were included; the 2-year follow-up analyses involved 41 children with IUGR and 68 comparison children. At baseline, children with IUGR showed deficits in divided, focused, and sustained attention. They were less accurate, exhibited more variability in reaction time, and performed more slowly and more impulsively than did the children in the comparison sample. After 2 years of hGH treatment, the IUGR group exhibited deficits in divided and sustained attention. They were still less accurate and showed more variability in reaction time and more impulsiveness. Current head circumference, the type of delivery, and global intelligence of children with IUGR were significantly correlated with attention measures. We hypothesize that short stature following IUGR and attention deficits are related, and that hGH treatment seems to have some beneficial effect on attentional capacity.

Psychosocial functioning of children, adolescents, and adults following hypospadias surgery: a comparative study.

Used standardized questionnaires to compare psychosocial functioning of 116 children and adolescents (9 to 18 years) and 73 adults (18 to 38 years) operated on for hypospadias, a congenital penile anomaly, with that of 88 and 50 age-matched comparison males, respectively, treated for an inguinal hernia. The relationships of coping with penile appearance, subject age, severity of hypospadias, number of operations, age at final surgery, and type of surgical procedure with psychosocial functioning were also investigated. Hypospadias patients did not exhibit a poorer psychosocial functioning and no significant relationships of various medical characteristics with psychosocial functioning could be discerned. Genital/body perception of hypospadias patients ages 9 to 18 years correlated positively with psychosocial functioning, albeit with low values. These findings are important for psychologists and specialists in the counseling process of hypospadias patients and their parents.

Factors associated with child mental health service use in the community.

OBJECTIVE: To determine the association of parent, family, and child factors with mental health services need and utilization. METHOD: Possible determinants of services need and utilization were assessed in a general population sample of 2,227 children aged 4 to 18 years. RESULTS: 3.5% of the total sample had been referred for mental health services within the past year. The most potent factors associated with service need and utilization were the child's problem behaviors (both internalizing and externalizing) and academic problems and family stress. Socioeconomic factors and the child's sex were not in itself associated with help-seeking factors. Parental psychopathology, life events, and family psychopathology lowered the parents' threshold for evaluating the child's behavior as problematic but did not increase the likelihood of referral. CONCLUSION: Referred children are more likely to live in families under stress than are children with the same level of problems who live in well-functioning families. Clinicians and researchers who make inferences from findings in clinical samples should realize, therefore, that children from problem families are overrepresented in their samples.

Comparisons of problems reported by parents of children in 12 cultures: total problems, externalizing, and internalizing.

OBJECTIVE: To compare parent-reported problems for children in 12 cultures. METHOD: Child Behavior Checklists were analyzed for 13,697 children and adolescents, aged 6 through 17 years, from general population samples in Australia, Belgium, China, Germany, Greece, Israel, Jamaica, the Netherlands, Puerto Rico, Sweden, Thailand, and the United States. RESULTS: Comparisons of 12 cultures across ages 6 through 11 and 9 cultures across ages 6 through 17 yielded medium effect sizes for cross-cultural variations in Total Problem, Externalizing, and Internalizing scores. Puerto Rican scores were the highest, while Swedish scores were the lowest. With great cross-cultural consistency, Total and Externalizing scores declined with age, while Internalizing scores increased; boys obtained higher Total and Externalizing scores but lower Internalizing scores than girls. Cross-cultural correlations were high among the mean item scores. CONCLUSIONS: Empirically based assessment provides a robust methodology for assessing and comparing problems reported for children from diverse cultures. Age and gender variations are cross-culturally consistent. Although clinical cutoff points should not necessarily be uniform across all cultures, empirically based assessment offers a cost-effective way to identify problems for which children from diverse cultural backgrounds may need help.

Associations between different diagnostic approaches for child and adolescent psychopathology.

OBJECTIVE: To test the convergence between the empirical-quantitative approach of the Child Behavior Checklist (CBCL) and the clinical-diagnostic approach of the DSM. METHOD: The parent version of the NIMH Diagnostic Interview Schedule for Children (DISC), version 2.3, was administered after completion of the CBCL for 231 children and adolescents consecutively referred to an outpatient mental health clinic. RESULTS: Of the subjects with a DSM-III-R diagnosis, 60% scored in the clinical range of the CBCL total problem score. The Withdrawn scale predicted affective and anxiety disorders. The Somatic Complaints scale predicted anxiety and mood disorders and Attention Deficit Hyperactivity Disorder. The Anxious/Depressed scale predicted anxiety and mood disorders and, to a lesser extent, disruptive behavior disorders. The Social Problems scale predicted Oppositional Defiant Disorder. The Attention Problems scale was the only significant predictor of "pure" Attention Deficit Hyperactivity Disorder (ADHD). The Aggressive Behavior scale predicted several disruptive behavior disorders, and Major Depression. The Delinquent Behavior scale was strongly associated with Conduct Disorder. CONCLUSIONS: Empirically based CBCL scale scores and DISC-P based DSM-III-R diagnoses converged. However, both approaches do not converge to a degree that one approach can replace the other. Instead, combining both approaches may be valuable by adding information from one approach that is not captured by the other.

Ten-year time trends of psychopathology in Dutch children and adolescents: no evidence for strong trends.

The 10-year time trends in competencies and problem scores in children and adolescents were assessed. Children and adolescents randomly selected from the Dutch general population in 1983 were assessed with the Child Behavior Checklist and the Teacher's Report Form. Their problem scores and competence scores were compared with those obtained by the same method 10 years later. No significant differences were found between the 1983 and 1993 total problem scores obtained from parents or teachers. On the level of problem items and scales, a few differences indicating an increase in problems were found. However, the magnitude of these differences was very small. Our results did not provide evidence for a clear secular increase in malfunctioning of Dutch children and adolescents.

Parent, teacher and self-reports as predictors of signs of disturbance in adolescents: whose information carries the most weight?

We evaluated the ability of parents, teachers and self-reports to predict signs of maladjustment in 353 11- to 14-year-olds from the general population, over a 4-year time interval. Odds ratios were computed in order to test the ability of problem scales to predict later mental health referral and measures of parents' and children's own perceptions of the existence of major problems. Each informant made its own unique and indispensable contribution to the prediction of signs of maladjustment. Although teachers are often perceived as less able to assess internalizing problems than mothers and the children themselves, the present study showed that teachers' evaluations of internalizing problems are highly relevant if we take their ability to predict the subject's own perceptions of having problems as the criterion.

The prevalence of self-reported problems in young adults from the general population.

This study assessed the prevalence of a wide range of behavioral and emotional problems in 706 19- to 24-year-olds from the Dutch general population using the Young Adult Self-Report (YASR). The prevalence rates found can be used to make comparisons with data from individuals or other samples. Large or medium (variance > 5.9%) sex effects were found for alcohol use, for the items 'Brags' and 'Swears' (males > females), and for the items 'Cries a lot' and 'Fears' (females > males). With respect to socially desirable items, females more often reported attitudes or behaviors pertaining to helping other people, while males more often reported competitive behaviors or attitudes. For YASR syndromes, higher mean scores for females than males were found for the Withdrawn, Somatic Complaints, and Anxious/Depressed syndromes, while mean scores on the Delinquent Behavior syndrome were higher for males than females. No age effects were found, indicating that normative data were similar across the 19- to 24-year age span. Compared to other problem areas, thought problems and delinquent behavior in males, and social problems and delinquent behavior in females were least likely to be associated with other types of problems. Hence, instruments for the assessment of psychopathology in young adults should include these areas to provide a comprehensive picture of behavioral and emotional problems.

Cross-cultural generalizability of the Youth Self-Report and Teacher's Report Form cross-informant syndromes.

Exploratory factor analyses on 569 Youth Self-Reports and 1,221 Teacher's Report Forms of clinically referred Dutch children revealed six and eight factors respectively, very similar to the eight YSR and TRF cross-informant syndromes derived by Achenbach (1991c, 1991d). Mean cross-cultural correlations were .89 for YSR syndromes and .95 for TRF syndromes. In confirmatory factor analyses of the Dutch and American YSR and TRF factor models in cross-validation samples of 570 YSRs and 1,221 TRFs, goodness-of-fit indices were only slightly better for Dutch factor models. The American cross-informant Social Problems and Attention Problems syndromes had the poorest fit. The application of the eight American cross-informant syndromes to Dutch self- and teacher reports was supported.

A genetic study of maternal and paternal ratings of problem behaviors in 3-year-old twins.

Genetic and environmental influences on problem behaviors were studied in 3-year-old twins. Fathers' and mothers' ratings of problem behaviors in twins-236 monozygotic (MZ) girls, 210 MZ boys, 238 dizygotic (DZ) girls, 265 DZ boys, and 409 DZ opposite sex pairs- were obtained with the Child Behavior Checklist for Ages 2-3 (T.M. Achenbach, 1992). Twin correlations and results from a model fitting approach showed that genetic, shared environmental, and nonshared environmental influences accounted on average for about 64%, 9%, and 27% of the variance. Although shared environmental influences were small for most scales, they were important for Total Problems and somewhat larger for Externalizing than for Internalizing behaviors. Significant sex differences in genetic and environmental influences and evidence for sibling contrast effects were found for the Overactive scale.

Self-concept before and after two years of growth hormone treatment in intrauterine growth-retarded children.

The objective of this study was to assess self-concept in children with short stature after intrauterine growth retardation (IUGR), before and after 2 years of growth hormone (hGH) treatment. We assessed 25 children before treatment, and 40 children after a 2-year treatment period. Seventeen of the 25 children of whom we had pretreatment data, were reassessed after 2 years of hGH treatment. All children had a birth length below the 3rd percentile, and did not show catch-up growth (current height < P3). We compared the self-concept measures (Self-Perception Profile for Children; SPPC) of the IUGR group with similar measures of a Dutch school sample. Four of the six SPPC mean scale scores of the IUGR group prior to treatment were significantly lower than mean scores of the school sample. Mean-scale scores of the group children, assessed after 2 years of hGH treatment, did not differ significantly from those of the school sample. In the group of 17 children who were assessed before as well as after 2 years of treatment, the mean scale scores of 'social acceptance' and 'general self-worth' were significantly higher at the second assessment (t = -5.93, p < 0.001 and t = -4.36, p < 0.001, respectively). From the present study we can hypothesize that short stature after IUGR and a low self-concept are related.

Satisfaction with penile appearance after hypospadias surgery: the patient and surgeon view.

PURPOSE: We studied the degree of agreement between hypospadias patient and surgeon satisfaction with the cosmetic surgical result, and the relation between penile length, meatal position and patient satisfaction. MATERIALS AND METHODS: Cosmetic and functional results in 35 boys with hypospadias were assessed, and a standardized questionnaire was completed by patients and surgeon. RESULTS: There was hardly any agreement between patient and surgeon satisfaction with patient penile appearance. Patients were less satisfied than the surgeon. No significant correlation was noted between penile satisfaction and penile length. Patients with a retracted meatus were less satisfied with the meatal position than those with a glanular meatus. Of the 35 patients 4 underwent repeat surgery after our study. CONCLUSIONS: Hypospadias surgeons should explicitly asked if patients are satisfied and they should follow patients through adolescence.

Psychopathology in Dutch young adults: enduring or changeable?

This study reports on stability and change in emotional and behavioral problems in young adults over a 2-year time span. A sample of 528 18- to 22-year-olds from the general population was assessed using the Young Adult Self-Report (YASR) on two occasions. Stability coefficients for the total problem score of the YASR were 0.63 for males and 0.75 for females. Forty-nine percent of the subjects who were initially classified as deviant were still deviant at follow-up. Of all YASR syndromes, the highest stability was for the Anxious/Depressed scale.

Empirically based assessment and taxonomy of psychopathology: cross-cultural applications. A review.

This paper provides an overview of empirically based assessment and taxonomy, as illustrated by cross-cultural research on psychopathology. The empirically based approach uses standardized assessment procedures to score behavioral and emotional problems from which syndromes are derived by multivariate analyses. Items and syndromes are scored quantitatively to reflect the degree to which individuals manifest them, as reported by particular informants. Although the approach to assessing problems and to constructing taxonomic groupings differs from the ICD/DSM approach, there are no inherent contradictions between either their models for disorders nor the criterial features used to define disorders. Cross-cultural comparisons have yielded relatively small differences in problem rates and syndrome structure, plus considerable similarity in associations of problems with sex and SES, as well as similar correlations between reports by different types of informants. Research on variations in problems in relation to culture, sex, age, SES, and type of informant can contribute to improving both the ICD/DSM and empirically based approaches and to a more effective synthesis between them.

Siblings of childhood cancer survivors: how does this "forgotten" group of children adjust after cessation of successful cancer treatment?

Siblings of childhood cancer patients are labelled the "forgotten children" because they experience significant psychosocial distress and are isolated from support systems inside and outside the family. This study investigates the late consequences of the cancer experience for siblings. 60 siblings of cancer survivors were compared with control subjects on measures of psychosocial adjustment. No differences were found between siblings of cancer survivors and controls on emotional and behavioural problems and competence, suggesting that siblings adjust well to the period after cessation of treatment. The effect of demographic, family and disease-related characteristics on the siblings' psychosocial adjustment was limited. Whereas during treatment many psychosocial problems for siblings have been reported, this does not result in a heightened risk of psychological disturbance for siblings as a late effect. The implications for patient care are discussed.
