Objective: Disorders related to overcontrol frequently first appear during adolescence, are highly comorbid, and show limited treatment response, necessitating the adaptation of radically open dialectical behavior therapy (RO DBT; a transdiagnostic treatment targeting overcontrol) for adolescents (RO DBT-A). This study tested the preliminary efficacy of telehealth-delivered RO DBT-A in a heterogeneous clinical sample of youths.
Methods: The sample consisted of 20 female participants ages 13-21 with elevated overcontrol; most were White (75%) and non-Hispanic/Latino (80%). RO DBT-A was provided over 20 weeks via skills group and individual sessions (N=13 participants). Participants seeking other treatment or no treatment formed the control group (N=7). Outcomes included self-reported symptoms and overcontrol. Follow-up interviews were analyzed by using inductive, contextualist thematic analysis to examine participant perceptions and reasons for dropout.
Results: The RO DBT-A group showed significant improvements in depression (t=-1.78, df=10, p=0.011) and quality of life (QOL; Wilcoxon W=75, p=0.021) compared with the control group. From baseline to posttreatment, youths receiving RO DBT-A demonstrated significant improvements in maladaptive overcontrol (t=2.76, df=12, p=0.043), anxiety (t=2.91, df=12, p=0.043), depression (Wilcoxon signed rank V=82.5, p=0.043), and QOL (t=-3.01, df=12, p=0.043). Qualitative analysis revealed themes related to treatment barriers, facilitators, and timing.
Conclusions: The findings provide preliminary evidence supporting telehealth-delivered RO DBT-A in targeting overcontrol, decreasing symptomatology, and improving QOL in a heterogeneous clinical sample of youths. Qualitative follow-ups highlighted that dropout was driven by barriers related to therapy (e.g., structure- and therapist-related issues) and the timing of RO DBT-A compared with other treatments.
