| Abstract: | This study aimed to assess whether changes in potentially modifiable risk factors associated with the construct of neuroticism and common to emotional disorders (i.e., poor distress tolerance and heightened avoidance) occur in concordance with the administration of different treatment components of the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Adolescents (UP-A) and with reductions in emotional disorder symptoms (i.e., anxiety and depressive symptoms) overall. Using single-case analytic strategies, including multiple-baseline design and modeling techniques, the authors treated 8 adolescents with emotional disorder diagnoses and evaluated trajectories of change in distress tolerance and experiential avoidance as well as in the sequencing of such change in regard to change in anxiety and depressive symptoms. Clinical outcomes were favorable based on parent, adolescent, and clinician-rated measures. Treatment-based change was demonstrated, at both group and individual levels, and at expected points in treatment, in regard to facets of neuroticism. Overall, self-reported change in experiential avoidance and distress tolerance tended to occur simultaneously to reductions in emotional disorder symptoms. This study helps to clarify the course of expected change in variables believed to be common among a range of emotional disorders during a transdiagnostic treatment and provides initial information regarding tailoring the UP-A for individuals with different clinical profiles. |
