To determine eligibility, all participants undergo an online prescreen and a face-to-face screening assessment. Participants who qualify for the study then complete a baseline (pre-treatment) assessment, followed immediately by the treatment procedure and a post-treatment assessment. Participants return to the lab an average of 14 days after treatment to complete a follow-up assessment. Participants complete two behavioral approach tests (in the treatment context and in the generalization context) at baseline, post-treatment, and follow-up, and a battery of self-report questionnaires at baseline and follow-up.
