ABSTRACT
The present study investigated whether an 8-day intensive treatment for panic disorder in adolescents conferred a corollary benefit of ameliorating symptoms of depression. Participants included 57 adolescents between the ages of 11 and 18 who were randomly assigned to an intensive panic treatment for adolescents with or without parental involvement. Paired samples t tests and hierarchical linear models (HLM) indicated that participants' total depression score and scores on depression subscales declined from baseline to the 3-month follow-up. Additional HLM analyses indicated that the interaction term between age and parent involvement was a significant moderator in the negative slope for adolescent depression, with younger participants benefitting more from treatment without parent involvement than older participants with regard to depression symptoms.
ABSTRACT
Much remains to be learned about typical and individual growth trajectories across treatment for adolescent panic disorder with and without agoraphobia and about critical treatment points associated with key changes. The present study examined the rate and shape of change across an 8-day intensive cognitive behavioral therapy for adolescent panic disorder with and without agoraphobia (N = 56). Participants ranged in age from 12 to 17 (M = 15.14, SD = 1.70; 58.9% female, 78.6% Caucasian). Multilevel modeling evaluated within-treatment linear and nonlinear changes across three treatment outcomes: panic severity, fear, and avoidance. Overall panic severity showed linear change, decreasing throughout treatment. In contrast, fear and avoidance ratings both showed cubic change, peaking slightly at the first session of treatment, starting to decrease at the second session of treatment, and with large gains continuing then plateauing at the fourth session. Findings are considered with regard to the extent to which they may elucidate critical treatment components and sessions for adolescents with panic disorder with and without agoraphobia.
