Sponsor's own description
This study is a randomized controlled pilot trial using a hybrid type 1 effectiveness-implementation design to evaluate the feasibility, acceptability, and preliminary effectiveness of a brief cognitive-behavioral intervention delivered by medical assistants in a primary care setting. The trial compares clinical outcomes of participants assigned to the intervention condition to those of participants assigned to a usual care condition. The clinical outcome is change on a self-report measure of health anxiety. Assessments occur at baseline, four weeks, and 12 weeks post-treatment. The study will also measure engagement with the intervention and assess feasibility and acceptability of the intervention in terms of fidelity of trained study therapists and ratings of the intervention by participants. The usual care condition consists of a referral to a mental health provider. The intervention is comprised of four sessions of individually administered cognitive-behavioral therapy addressing health anxiety. Treatment focuses on building motivation for change, psychoeducation about health anxiety, cognitive restructuring, and situational and interoceptive exposure. The study will recruit from three primary care clinics within the Dartmouth-Hitchcock Health system. The study will also assess facilitators and barriers to implementation using qualitative analyses of interview responses provided by the medical assistants delivering the intervention, primary care providers, and clinic administrators at the study sites.
