Published 1985Staff ViewISSN: 1469-7610Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicinePsychologyNotes: In this study the prevalence of nocturnal enuresis defined according to the DSM III criteria was determined in a random sample of 2070 children aged from 4 to 16 years. Nocturnal enuresis declines in prevalence with age and is more frequent in boys than in girls. Moreover, the decline in prevalence with age was found to take place earlier in girls than in boys. It is therefore argued that the DSM III age limit for enuresis should be raised to 8 years for boys.Type of Medium: Electronic ResourceURL: -

Published 1988Staff ViewISSN: 1469-7610Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicinePsychologyNotes: Abstract 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.Type of Medium: Electronic ResourceURL: -

Published 2001Staff ViewISSN: 1469-7610Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicinePsychologyNotes: Child Behavior Checklist questionnaires (Achenbach, 1992), filled in separately by mothers and fathers, were collected for an effective sample of 3501 Dutch 3-year-old twin pairs. To disentangle the child's phenotype from that of the rater, two contrasting models were fitted to the data. One model, called a Rater Bias model, is based on the assumption that both parents assess exactly the same behaviors in the child. A weaker alternative of this model, called a Psychometric model, assumes that apart from these common behavioral views, each parent also assesses a unique aspect of the child's behavior. A Psychometric model fitted the data of both Internalizing and Externalizing scales significantly better than a Rater Bias model. This implied that each parent provided unique information from his or her own perspective, apart from the common behavioral view. Using this best fitting model, the etiology of both the Internalizing and Externalizing scales was studied. Common factors (influencing behaviors similarly assessed by both parents) were more important than unique factors (influencing behaviors uniquely assessed by one parent). Common genetic factors explained about 50% of the variance of both scales, indicating a possible inborn vulnerability to childhood psychopathology. Common environmental factors not shared between twins (free of unreliability and error) explained around 14% of both scales, suggesting the importance of pure idiosyncratic experiences even for children as young as 3 years. Common environmental factors shared between twins (unconfounded by rater bias) were only found for the Externalizing scale, explaining 18% of the variance. Rater bias and unreliability, if present in the data, were included in the estimates of the unique factors. Unique genetic, shared, and nonshared environmental factors each explained around 8% of the variance for both scales. These small effects could be detected because of the large sample of twin pairs used.Type of Medium: Electronic ResourceURL: -

Published 1987Staff ViewISSN: 1469-7610Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicinePsychologyNotes: Abstract— Parents' and children's reports of behavioural-emotional problems in 116 children assessed by the Child Assessment Schedule developed by Hodges et al. (Journal of the American Academy of Child Psychiatry, 21, 468–473, 1982) and the Graham & Rutter Parent Interview (British Journal of Psychiatry, 114, 581–592, 1968), both semi-structured interviews, revealed relatively high agreement compared with studies using highly structured assessment procedures. The majority of disagreements could be attributed to higher parents's cores. Only fears were reported more often by children, especially by the better-functioning children, suggesting that children's reports of fears may be related to a higher level of adaptive functioning rather than a higher level of psychopathology. Although the child interview may be crucial to obtain information often not reported by parents such as fears and anxiety, it was found that information from the child contributed only little to overall clinical judgeament based on information already available from the parents.Type of Medium: Electronic ResourceURL: -

ISSN: 1433-0474Keywords: Schlüsselwörter Körperliche Beschwerden ; CBCL/4 ; 18 ; Kultur-vergleichend ; Kinder ; Jugendliche ; Key words Somatic complaints ; Cross-cultural ; Children ; AdolescentsSource: Springer Online Journal Archives 1860-2000Topics: MedicineDescription / Table of Contents: Summary Question: What is the frequency of parent-reported somatic complaints of children in Germany and the Netherlands dependent on their age, sex and the education of their parents. Methods: 4876 CBCL (Child Behaviour Checklist) of children aged 4 through 17 years from the general population were analysed. Results: Dutch children were scored higher by their parents than German children. Moreover somatic complaints increased with age and girls were scored higher. The frequencies of somatic complaints varied from 2% for ’problems with eyes’ to 15% for ’headaches’. The presence of one somatic complaint increased the likelihood of concomitant somatic complaints. Conclusion: Somatic complaints of children without any known cause are often seen. Some symptoms are often reported together. More, especially causal studies on the somatic symptoms of children are recommended.Notes: Zusammenfassung Fragestellung: Wie verhält sich die Häufigkeit körperlicher Beschwerden bei Kindern in Deutschland und den Niederlanden nach Laieneinschätzung, gibt es Unterschiede abhängig vom Alter und Geschlecht der Kinder und des Ausbildungsniveaus der Eltern? Methode: 2757 deutsche und 2119 niederländische CBCL (child behavior checklist) über Kinder und Jugendliche im Alter zwischen 4 und 17 Jahren aus repräsentativen Studien wurden mit Hilfe von Varianzanalysen ausgewertet. Ergebnisse: Niederländische Eltern beschrieben mehr körperliche Beschwerden als deutsche. Die Ausprägung auf der Symptomskala stieg mit zunehmendem Alter und zeigte höhere Werte für Mädchen. Die Häufigkeit der Beschwerden variiert von 2% für „Augenbeschwerden” bis zu 15% für „Kopfschmerzen”. Bei Anwesenheit eines körperlichen Symptoms stieg die Frequenz zusätzlicher Beschwerden. Schlußfolgerung: Körperliche Beschwerden bei Kindern treten häufig ohne bekannte Ursache auf, bestimmte Beschwerden werden häufig gleichzeitig beschrieben, wobei die Koinzidenz nicht umkehrbar ist. Weitere, besonders ursächliche Studien auf dem Gebiet der körperlichen Beschwerden bei Kindern sind auch hinsichtlich steigender Kosten im Gesundheitswesen empfehlenswert.Type of Medium: Electronic ResourceURL: -

ISSN: 1433-9285Source: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract Parents' reports of problem behaviors in 2,081 Dutch children, 3,127 Turkish children in Ankara and 833 Turkish immigrant children living in The Netherlands, aged 4–18 years, were compared. Dutch and Turkish versions of the Child Behavior Checklist (CBCL) were used. Immigrant children were scored higher than Dutch children on 6 of the 11 CBCL scales, most markedly on the Anxious/Depressed scale. Immigrant children were scored higher than Ankara children on five CBCL scales. However, these differences were much smaller than those found between immigrant and Dutch children. Furthermore, immigrant children's Total Problem scores did not differ from those for Ankara children. Turkish immigrant children have very similar patterns of parent-reported problem behaviors to children living in Turkey, although both groups of Turkish children showed higher levels of parent-reported problem behaviors than Dutch children. The higher scores for Turkish children on the Anxious/Depressed scale compared with their Dutch peers may be explained by cultural differences in parental perception of children's problem behaviors, as well as the threshold for reporting them, or by cultural differences in the prevalence of problems, for instance as the result of cross-cultural differences in child-rearing practice. More research is needed to test the degree to which Turkish immigrant parents tend to preserve their cultural characteristics and child-rearing practices in Dutch society.Type of Medium: Electronic ResourceURL: -

ISSN: 1433-9285Source: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract This study assessed the prevalence of a wide range of behavioral and emotional problems in 706 10-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.Type of Medium: Electronic ResourceURL: -

ISSN: 1433-9285Source: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract 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.Type of Medium: Electronic ResourceURL: -

ISSN: 1433-9285Source: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract Background: The objective of this study was to examine the relationship between child, parent, family/support, and stress variables and problem behaviors in Turkish immigrant children in the Netherlands. Methods: Parents of 833 children were interviewed and administered a Turkish version of the Child Behavior Checklist for ages 4 through 18 and a Turkish immigrant assessment questionnaire. Results: Increased integration (i.e., children belonging to a second generation of immigrants, older children) generally reduced the risk for problem behaviors, while frequent arguments, divorce, psychological problems, and convictions/incarcerations increased the risk for problem behaviors. Conclusions: Results indicate that problem behaviors are associated with the high level of separation faced by Turkish immigrant families and that more integration leads to lower levels of problem behavior. Additionally, migration history alone does not contribute to problem behavior. Factors in the family (e.g., quarrels, divorce, conviction) associated with problem behaviors in Turkish immigrants are similar to those found in Dutch and American populations. Future studies could examine predictors of problem behaviors in other culturally separated immigrant groups in the Netherlands, and in Turkish immigrant groups in other countries.Type of Medium: Electronic ResourceURL:
