Background: Given the relatively high prevalence of anxiety problems among young people and their adverse consequences if left untreated, it is important that clinicians and researchers have access to reliable and valid assessment tools to facilitate early detection, case formulation, treatment design and evaluation of outcomes. Method: This paper presents the findings of a pragmatic review of the literature regarding the assessment of anxiety in young people in multiple contexts, including mental health services, school-based screening and research trials. Results: Commonly used diagnostic interviews, questionnaire measures and alternative assessment methods are described, along with psychometric properties and practical issues. The review indicates the complexities of assessing anxiety problems given the high level of comorbidity between anxiety disorders and with depression. It also highlights the different approaches required for assessment across different age groups, the need for multiple informants and issues relating to the lack of agreement between reporters. There is a strong evidence-base for several diagnostic instruments and anxiety scales, although the accuracy of youth and parent report scales in forming clinical diagnoses is not sufficiently strong to justify their use in isolation for diagnostic purposes. Conclusions: The assessment of youth anxiety should ideally include a multiinformant, multimethod approach, with measures tailored to the age of the child, and the purpose of the evaluation. There is now a sufficiently strong research base to enable clinicians and researchers to ensure that they select evidence-based instruments. Key Practitioner Messages• The assessment of anxiety in children and adolescents needs to take a multiinformant approach, but we need to recognize that there is often weak agreement between parents, teachers and youth.• Assessment needs to examine the different types of anxiety disorder and potential comorbidity between them and other disorders.• A developmental approach is required, to ensure that measures are appropriate for the age of the child. • Multidimensional anxiety scales completed by parent and youth provide a strong supplement to diagnostic interviews in the assessment process, to inform the case formulation and treatment planning, but should not be used in isolation to provide clinical diagnoses.• More detailed measures for specific types of anxiety may be used, in addition to scales suitable to specific subpopulations.

“…The ADIS-C/P has previously proven to be a reliable instrument for assessing anxiety disorder symptoms and diagnoses based on the DSM-IV, with good to excellent test-retest reliability (26). In the RCT study used as the PT group benchmark, an interrater reliability check of the Danish version of ADIS-C/P was conducted by two trained assessors watching and rating 22 (20.2%) of the videorecorded baseline interviews (24). The interrater reliability (Cohen's κ) for the primary anxiety diagnosis was 0.77.…”

Background: Several systematic reviews have demonstrated the efficacy of cognitive behavioral therapy (CBT) treating anxiety disorders in children and adolescents (hereafter referred to as youths). Treatment of anxiety disorders conducted by student therapists (ST) has been found to be an effective alternative, to treatment conducted by psychologists. Objective: The primary aim of the study is to investigate the effects of ST treating youths, using a group-based CBT program. Second, the study aims to compare these results with outcomes achieved by professional-therapists (PT). Method: The study investigate in an open trial design, the treatment outcome from a manualized CBT program (Cool Kids) in a group of youths (n = 54) treated by ST. Results are benchmarked against the outcomes of a group of youths (n = 56) treated by PT using the same program, derived from a separate randomized controlled trial. Results: There was a significant reduction of both self-reported and clinician rated measures of youth anxiety over time in the ST group, with small to large effect sizes. No significant differences of improvements in self-report measures were found between the ST and the PT groups. There was no significant difference in remission rates for participants' primary anxiety disorder between the ST (50.0%) and the PT (66.1%) at post-treatment or at three-month follow-up (ST: 74.1%, PT: 76.8%). There was a significant difference regarding number of youths free of all anxiety disorder between the ST (14 [25.9%]) and PT (27 [48.2%]) group at post-treatment. This difference was not significant at three-month follow-up (ST: 25 [46.3%], PT: 33 [58.9%]). Conclusion: The findings support previous findings, suggesting that student-therapists, receiving training and supervision, can successfully treat youths with anxiety disorders using a manualized CBT program. The outcomes following CBT treatment conducted by ST are comparable to outcomes achieved by PT.

“…2) Precision: We lowered SOE one or two levels based on the confidence intervals and sample size. If confidence intervals included appreciable benefits and harms (crossing no effect), or the total sample size was lower than 400 (an arbitrary cutoff that corresponds to a standardized small effect of 0.20 with significance of 0.05 and power of 0.80), 30 we rated SOE down by one level. When both of these situations were encountered simultaneously, we rated SOE down twice for imprecision and labeled this scenario as "severe imprecision".…”
