The Penn State Worry Questionnaire for Children (PSWQ-C; Chorpita, Tracey, Brown, Collica, & Barlow, 1997) is a 14-item self-report measure of worry in children and adolescents. Although the PSWQ-C has demonstrated favorable psychometric properties in small clinical and large community samples, this study represents the first psychometric evaluation of the PSWQ-C in a large clinical sample (N = 491). Factor analysis indicated a two-factor structure, in contrast to all previously published findings on the measure. The PSWQ-C demonstrated favorable psychometric properties in this sample, including high internal consistency, high convergent validity with related constructs, and acceptable discriminative validity between diagnostic categories. The performance of the 3 reverse-scored items was closely examined, and results indicated retaining all 14 items.

We examined client outcomes from the implementation of Multisystemic Therapy (MST) in a statewide child and adolescent mental health system. Specifically, we examined (1) the validity of therapist-rated MST outcome measures by comparing them to ratings of functional impairment and level of service needs by CAMHD care coordinators, who provide case management and care coordination services, (2) potential client and service predictors of therapist-rated outcomes, and (3) improvement in youth functioning around the time of entry to and exit from MST compared with rates of improvement reported in randomized controlled trials (RCTs) by the developers of MST. Results suggested that therapist-rated MST outcomes were valid indicators of treatment success. Similar to other findings in the MST literature, few client or service characteristics predicted these outcomes. Finally, although MST entry-exit effect sizes were lower than the mean derived from RCTs published by the developers, they were within the 95% confidence interval. Together, these findings support the implementation of MST in complex systems of care with continued attention to quality assurance and ongoing use of data for evaluation.

Within a comprehensive mental health service array for youth, Intensive Home Based Services (IHBS) are designed to meet the needs of youth with significant emotional and behavioral problems in their home communities, avoiding the need for out-of-home services, particularly residential care. We examined youth receiving IHBS as their first service in the state of Hawaii system of care (N = 163) to determine how successful IHBS were in preventing the need for more restrictive services within 12 months of intake. Subsequently, we investigated characteristics that might be predictive of a youth's need for service intensification within 12 months. Logistic regression analyses found that greater age, level of service need, and functional impairment at intake predicted use of more restrictive services within 12 months of intake, whereas gender, ethnicity, diagnosis, service intensity, and clinician credentials did not. Overall, our findings suggested that IHBS were reasonably successful in preventing residential placements, and provided some basis for determining characteristics of youth likely to require more restrictive placements within a one year period.

Treatment outcome research has rarely allowed investigators to declare how or why therapeutic techniques work. As an initial step to understand such change processes, the current study investigated the timing of positive changes typically achieved during a course of cognitive-behavioral therapy for anxiety reduction. Using an interaction element multiplebaseline design across four children ( N = 4) diagnosed with selected anxiety disorders, anxiety levels, cognitive errors, and treatment outcome were repeatedly assessed as children progressed through four a priori determined treatment sequences. Results varied across reporters, dependent variables, and the order in which each treatment technique was delivered. Child-reported trends were slightly clearer than those reported by parents and suggested that exposure was a key element for triggering some (but not all) positive changes after completing self-monitoring and psychoeducation techniques.
