Comorbidity and Factors Affecting Treatment Non-Persistence in ADHD

Effects of Compliance to a Training Intervention for High School Students with ADHD

OBJECTIVE

We evaluated the effects of treatment compliance with the Challenging Horizons Program (CHP) for high school aged adolescents with attention-deficit hyperactivity disorder (ADHD).

METHOD

Participants were 185 high school aged adolescents (65% non-Hispanic White; 79% male) with a diagnosis of ADHD who were randomly assigned to either CHP or community control. Outcomes included parent-rated academic functioning, parent- and self-rated social-emotional functioning, and GPA. The complier average causal effect (CACE) was estimated using propensity-weighted models for youth engaging in ≥ 30 CHP individual sessions (15-20 min) across the academic year.

RESULTS

Most (78%) CHP participants engaged in≥30 CHP sessions. CACE analyses using latent growth curve modeling revealed significant treatment effects among treatment compliers across ratings of academic and social outcomes relative to similar control participants. For most outcomes, CACE estimates were larger than those found in intent-to-treat analyses, especially at 6-months follow-up.

CONCLUSIONS

Compliance with 30 or more individual CHP sessions appeared to be an attainable threshold associated with incremental gains across several academic and social outcomes. Effects of compliance were amplified at 6-months follow-up, supporting the hypothesized theory of change of training interventions. Future work should focus on facilitators of treatment engagement and feasibility of the CHP as delivered by high school personnel.

Cognitive behavioural group therapy for adolescents with ADHD: a study of satisfaction and feasibility

BACKGROUND

Adolescents with ADHD are at increased risk of adverse outcomes and a negative life trajectory into adulthood. Evidence regarding treatment specifically tailored for the needs of this age group are still limited. High dropout rates, discontinuation of medication and treatment resistance are common issues in this population, and the patient perspective on new treatment options is therefore important. In this study, we aimed to investigate treatment satisfaction and feasibility of a group CBT program for adolescents with ADHD. We further aimed to identify any baseline characteristics predicting satisfaction.

MATERIALS AND METHODS

This study was part of a larger RCT of group CBT as add-on treatment for adolescents aged 14-18 years (Mean age 15.9 years, SD 1.3) with ADHD in Norway. Satisfaction and feasibility in the treatment group (n = 48) were measured by completion of an evaluation questionnaire, attendance of group sessions and a group-leaders checklist. Predictors of satisfaction were analysed using linear regression.

RESULTS

Overall satisfaction was very high with a significant age effect, the eldest participants being most satisfied. Attendance rate was high with few dropouts and medical adherence during the treatment period was good. Group-leaders generally self-evaluated adherence to treatment manual positively but addressing resistance towards homework as challenging.

CONCLUSIONS

The participants were very satisfied with the group CBT treatment. Treatment options that are accepted and well-liked by the targeted population have the potential of reducing resistance towards treatment, improving future health and adherence to medication. The program is considered suitable for a clinical setting and may represent a feasible treatment supplement for adolescent ADHD.
