Differences in Anxiety and Depression Among Migrant and Non-Migrant Primary School Children in The Netherlands.

This is the first Dutch study investigating symptoms of five DSM-IV-classified anxiety disorders and depression in a large sample of pre-adolescent children with and without a migration background, adjusting for socioeconomic position (SEP) and social preference. Both are potential explanatory factors for differences in mental health among migrant children. We measured anxiety and depression scores with the self-report Revised Child Anxiety and Depression Scale (RCADS) in 2063 children (aged 8-13 years, 55% girls) in the Netherlands. Surinamese/Antillean, Turkish, and Moroccan children reported significantly higher anxiety scores than Dutch children. SEP and peer rejection partly explained higher anxiety scores. Surinamese/Antillean and Turkish children reported comparable depression scores to Dutch children, but Moroccan children reported lower depression scores after adjusting for SEP and peer rejection. Girls reported higher anxiety and depression levels across all four subgroups. Although differences between children with or without a migration background were small, these may increase in later life as the prevalence of anxiety and depression increases with age.

Indicated Prevention of Childhood Anxiety and Depression: Results From a Practice-Based Study up to 12 Months After Intervention.

OBJECTIVES: We investigated whether intervention effects of FRIENDS for Life, a school-based prevention program for children with anxiety or depression symptoms, were maintained over a period of 12 months after the intervention in a naturalistic setting. METHODS: We used a quasi-experimental design, with 339 children in the intervention group and 157 in the control group (aged 8-13 years) in schools in Amsterdam, the Netherlands. We collected self-, teacher, and peer reports of anxiety and depression scores before and after intervention, and 6 and 12 months after intervention, from 2010 to 2012. RESULTS: Intervention-group children reported a continuing and significant decrease in anxiety and depression scores compared with the control group. Twelve months after the intervention, participants' anxiety and depression levels were comparable to those of the general population. Girls reported a stronger decrease in anxiety scores than did boys. Teacher reports suggested no effects. Although classmates reported increased internalizing problems in intervention-group children immediately after intervention, these effects disappeared over time. CONCLUSIONS: FRIENDS for Life, an indicated prevention program, yielded long-lasting and continuing reduction in anxiety and depression problems when implemented in daily school practice.

Structure, reliability, and validity of the revised child anxiety and depression scale (RCADS) in a multi-ethnic urban sample of Dutch children.

BACKGROUND: Although anxiety and, to a lesser extent, depression are highly prevalent in children, these problems are, difficult to identify. The Revised Anxiety and Depression Scale (RCADS) assesses self-reported symptoms of anxiety and depression in youth. METHODS: The present study examined the factor structure, internal consistency, short-term stability, and validity including sensitivity to change of the RCADS in a multi-ethnic urban sample of 3636 Dutch children aged 8 to 13 years old. RESULTS: Results indicate that the RCADS is a reliable and valid instrument. The original 6-factor structure was replicated to a fair extent in the present study (RMSEA = 0.048) and internal consistency was good (αs = 0.70-0.96). ICCs for short-term stability were 0.76 to 0.86. Girls and children who indicated wishing to participate in a program targeting anxiety and depression had higher RCADS scores. Sensitivity to change analyses showed that the RCADS can detect changes in anxiety and depression symptoms in children who participated in a preventive intervention. The study showed low agreement between teacher and self-reported internalizing problems, even for children scoring above the 90(th) percentile of the RCADS, indicating a high level of problems, emphasizing the need to also take child reports into account when screening for anxiety and depression in children. CONCLUSION: This study shows that the RCADS can yield reliable data on a diversity of anxiety disorders and depression in urban children aged 8-13 from very diverse ethnic backgrounds.

Validity and reliability of the short Test Anxiety Inventory (TAI-5) in Dutch adolescents.

The present study examined the psychometric properties of the short Test Anxiety Inventory (TAI-5) in a Dutch adolescent sample. The sample consisted of 2063 secondary school students (mean age 13.6 years, 48% girls) who filled out a battery of screening questionnaires for a routine health check. We investigated structural validity with a confirmatory factor analysis, scale reliability with internal consistency coefficients, and construct validity with hypotheses testing and convergent validity. The proposed one-factor structure fitted well in the present sample. However, there was an indication of measurement variance for gender. Scale reliability was high (ω = 0.88), and sufficient positive correlations were found between TAI-5 scores and anxiety, depression, worry, executive functioning, and sleep problems (r ranging from 0.36 to 0.56). Girls had significantly higher test anxiety scores than boys (d = 0.47). The present study provided evidence for the validity and reliability of TAI-5 scores in a general population of Dutch adolescents.

Study design of 'FRIENDS for Life': process and effect evaluation of an indicated school-based prevention programme for childhood anxiety and depression.

BACKGROUND: Anxiety disorders and depression are highly prevalent in children and affect their current and future functioning. 'FRIENDS for Life' is a cognitive-behavioural programme teaching children skills to cope more effectively with feelings of anxiety and depression. Although 'FRIENDS for Life' is increasingly being implemented at Dutch schools, its effectiveness as a preventive intervention in Dutch schools has never been investigated. The aim of the study is to evaluate the effectiveness of 'FRIENDS for Life' as an indicated school-based prevention programme for children with early or mild signs of anxiety or depression. METHODS/DESIGN: This study is a controlled trial with one pre-intervention and three post-intervention measurements (directly after, and 6 and 12 months after the end of the programme). The study sample consists of children aged 10-12 years (grades 6, 7 and 8 of Dutch primary schools), who show symptoms of anxiety or depressive disorder. Data are collected through self-report, teacher report and peer nomination. A process evaluation is conducted to investigate programme integrity (whether the programme has been executed according to protocol) and to evaluate children's and parents' opinions about 'FRIENDS for Life' using online focus groups and interviews. DISCUSSION: The present study will provide insight into the effectiveness of 'FRIENDS for Life' as an indicated school-based prevention programme for children with early or mild signs of anxiety or depression.
