Predictors of Treatment Response in Anxious-Depressed Adolescents With School Refusal

OBJECTIVE To identify predictors of treatment response to 8 weeks of cognitive-behavioral therapy (CBT) among anxious-depressed adolescents with school refusal, half of whom received imipramine plus CBT and half of whom received placebo plus CBT. METHOD A hierarchical multiple regression analysis was used to evaluate the following variables as potential predictors of treatment response as measured by school attendance at the end of treatment: baseline severity (school attendance at baseline), drug group (imipramine versus placebo), presence of separation anxiety disorder (SAD), and presence of avoidant disorder (AD). RESULTS Baseline attendance, CBT plus imipramine, SAD, and AD were significant predictors of treatment response and accounted for 51% of the variance in outcome. Specifically, a higher rate of attendance at baseline and receiving imipramine predicted a better response to treatment whereas the presence of SAD and AD predicted a poorer response to treatment. The relationship between sociodemographic variables and treatment outcome was also evaluated. Age and socioeconomic status were unrelated to school attendance after treatment. Males had significantly higher rates of attendance after treatment than females. CONCLUSIONS Adolescents with school refusal are a heterogeneous population and require individualized treatment planning. Variables such as diagnosis and severity at the start of treatment should be taken into consideration when planning treatment.

Generalized anxiety disorder in a nonclinical sample of children: Symptom presentation and predictors of impairment

Presentation of generalized anxiety disorder (GAD) in a nonclinical sample of children (7-11 years old) and factors that predict overall impairment were examined. Symptom presentation was compared in children with GAD (n=49) and anxious children without GAD (n=42). Children with GAD endorsed significantly more worries, greater intensity of worries, and more DSM-IV associated symptoms than anxious children without GAD. Eighty-six percent of children with GAD had a comorbid diagnosis with 4% having a depressive disorder. Number of associated symptoms was most predictive of GAD impairment based on child perspective and intensity of worry was most predictive based on clinician perspective. Overall, findings from the current study are consistent with reports based on clinical samples. The DSM-IV-TR criteria for GAD were supported, with the exception that children with GAD typically present with several associated symptoms, rather than only one.
