Super Skills for Life (SSL) is a transdiagnostic prevention program for school-aged children with internalizing problems. The current study aimed to examine the short- and long-term (12-month follow-up) effectiveness of SSL, depending on implementation fidelity. Participants were 123 Spanish-speaking children aged 6-8 years with internalizing symptoms and their parents. High (n = 41) and low fidelity (n = 26) groups were established and compared with a control group (CG) (n = 56). Compared to CG, the high-fidelity group (HFG) achieved better outcomes than the low-fidelity group (LFG) at short and long term, including symptoms of anxiety, depression, and internalizing problems, and also externalizing problems at long-term. The LFG improved key symptoms at short term (depression) and long term (anxiety and depression). Findings suggest that SSL is beneficial even if not delivered at maximum fidelity, although considering the influence of implementation fidelity is critical because the high-fidelity implementation yielded the greatest effects when compared to the CG. This research provides valuable data, analyzing for the first time the influence of fidelity on SSL outcomes in young school-aged children exhibiting internalizing symptoms, while there is still a lack of studies of these characteristics concerning transdiagnostic prevention programs targeting childhood anxiety and depression., (Copyright © 2021.

The present study examined the psychometric properties of the Iranian translation of the Spence Children's Anxiety Scale (SCAS) in a large community sample of adolescents (N = 1984), aged 12-17 years, in Ahvaz City, Iran. In addition to the SCAS, all participants completed the Strengths and Difficulties Questionnaire (SDQ), and the Centre for Epidemiological Studies Depression Scale for Children (CES-DC). The internal consistency (Cronbach Alpha = .92) and the validity of the Iranian translation of the SCAS was excellent. The SCAS total scores correlated significantly with the CES-DC, as well as with the emotional, conduct problems, hyperactivity-inattention, and peer problems subscales of the SDQ. However, Steiger's Z test demonstrated that correlations between the SCAS scores and the SDQ conduct problems or hyperactivity-inattention subscales were significantly lower than the correlations between the SCAS scores and the SDQ emotional symptoms subscale. Confirmatory factor analyses revealed the same 6-factor structure as the original SCAS. The SCAS proved to be a reliable and valid measure of anxiety symptoms among adolescents in Iran., (Copyright © 2012 Elsevier Ltd. All rights reserved.)

The present study evaluated the effectiveness of a universal school-based cognitive behavior prevention program (the FRIENDS program) for childhood anxiety. Participants were 638 children, ages 9 to 12 years, from 14 schools in North Rhine-Westphalia, Germany. All the children completed standardized measures of anxiety and depression, social and adaptive functioning, coping strategies, social skills, and perfectionism before and after the 10-week FRIENDS program and at two follow-up assessments (6 and 12 months) or wait period. Children who participated in the FRIENDS program exhibited significantly fewer anxiety and depressive symptoms, and lower perfectionism scores than children in the control group at 12-month follow-up. Younger children (9-10-year-olds) displayed treatment gains immediately after the intervention, whereas older children (11-12-year-olds) showed anxiety reduction only at 6- and 12-month follow-up. Perfectionism and avoidant coping acted as mediators of pre- to postintervention changes in anxiety scores. This study provides empirical evidence for the utility of the FRIENDS program in reducing anxiety and depressive symptoms among German children., (Copyright © 2011. Published by Elsevier Ltd.)

This study examined the factor structure, reliability, and validity of the original Spence Child Anxiety Scale (SCAS) and its four translations (German, Cypriot Greek, Swedish, Italian). A total of 2558 adolescents from five European countries (Germany = 495; Cyprus = 611; UK = 469; Sweden = 484; Italy = 499), ages 12-17 years, participated in the study. In addition to the SCAS, all participants completed the Strengths and Difficulties Questionnaire, a measure of general difficulties and positive attributes. The internal consistency and validity (convergent and discriminant) of the SCAS were excellent. Multiple group confirmatory factor analysis provided strong support for the generalizability of a 6-factor inter-correlated model across five European countries. Adolescents in the UK had significantly higher anxiety levels than adolescents in four other European countries. Our findings suggest that the SCAS is suitable for assessing anxiety disorder symptoms in adolescents in Germany, the UK, Cyprus, Sweden, and in Italy., (Copyright © 2010 Elsevier Ltd.

This study examined the factor structure, reliability, and validity of the German translation of the Childhood Anxiety Sensitivity Index (CASI). A total of 1292 adolescents participated in the study. Analyses using the Schmid-Leiman solution showed the CASI to have one higher order factor and three orthogonal lower order factors. CASI scores correlated significantly with anxiety symptoms and with general difficulties. Hierarchical multiple regression showed CASI to make a significant contribution in predicting anxiety even after controlling for variance due to general difficulties, thus giving further support to the incremental validity of the CASI. The CASI is a potentially useful measure to include in longitudinal studies that examine the development of childhood and adolescent anxiety disorders.

The author examined the course of somatoform disorders in non-referred adolescents. Somatoform disorders were coded from DSM-IV criteria, using the computerized Munich (Germany) version of the Composite International Diagnostic Interview. About 35.9% of the adolescents with somatoform disorders at the index investigation continued to have the same disorders at the follow-up investigation: 26.7% had anxiety, 17.1% had depression, 22% had substance-use disorders, and 53.7% had no psychiatric disorders. Factors related to the chronicity of somatoform disorders included gender, comorbid depressive disorders, parental psychiatric disorders, and negative life events. Somatoform disorders showed a heterogeneous pattern of course.

The reliability and validity of the Spence Children's Anxiety Scale (SCAS) and the Screen for Child Anxiety Related Emotional Disorders (SCARED) were evaluated in a sample of 556 German primary school children. Both the SCAS (alpha = 0.92) and the SCARED (alpha = 0.91) were demonstrated to have high internal consistency. The validity of the SCAS and the SCARED was supported by a number of findings. First, in agreement with previous studies, girls displayed significantly higher levels of anxiety symptoms than boys. Furthermore, SCAS and SCARED scores were substantially interrelated. Finally, significant correlations were found between these two measures of anxiety symptoms and the Youth Self-Report and the Columbia Impairment Scale. The utility of the SCAS and the SCARED as screening instruments for anxiety symptoms in children is briefly discussed.

The aim of this article was to examine the course and outcome of anxiety disorders in German adolescents. Anxiety and other psychiatric disorders were coded based on DSM-IV criteria using the computerized Munich version of the Composite International Diagnostic Interview. About 22.6% of the adolescents who fulfilled DSM-IV criteria of any current anxiety disorders at the index investigation (T1) continued to have anxiety at the follow-up investigation (T2), 17.7% had depression, 27.4% somatoform, 6.5% substance use disorders, and 41.9% had no disorders. The factors that were significantly associated with the persistence of anxiety disorders included older age, presence of somatoform and substance use disorders, as well as a high number of negative life events at the T1-interview. Adolescents with "chronic" compared to "transient" anxiety disorders and those without any disorders were significantly more impaired in various life domains. Despite these high levels of psychosocial impairment, only a few of them did seek professional help in the last 12 months before the T2-interview.

The frequency, comorbidity, and psychosocial impairment of anxiety disorders among German adolescents was estimated from a survey of 1,035 students aged 12-17 years. The adolescents were randomly selected from 36 schools in the province of Bremen, Germany. Anxiety disorders and other psychiatric disorders were coded based on criteria from the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders, using the computerized Munich version of the Composite International Diagnostic Interview. Anxiety disorders occurred frequently in our sample of adolescents, with a rate of 18.6%. When considering the subtypes of anxiety disorders, phobia was the most common. Posttraumatic stress disorder and obsessive-compulsive disorder occurred less frequently with rates below 2%. Panic disorder and generalized anxiety disorder were the least common, with rates well below 1%. Anxiety disorders were significantly higher in girls than in boys, and that the rates increased with age. Comorbidity occurs quite frequently, both within the anxiety disorders and also with other psychiatric disorders. The most common pattern of comorbidity was that of anxiety and depressive disorders. Although a high number of anxiety cases were psychosocially impaired, at least during the worst episode of their disorders, only a few of them sought treatment for their problems. We conclude by discussing some research priorities in the area of anxiety disorders in children and adolescents.
