Accepts healthy volunteers: no
Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: If participant meets eligibility criteria, the participant will be randomly assigned to complete a one-session computer-delivered intervention: either (1) anxiety sensitivity reduction treatment or (2) health information control.
Primary purpose: TREATMENT

Brief summary: The proposed study will design and evaluate a computerized-delivered single-session anxiety sensitivity reduction program (i.e., Anxiety Sensitivity Training; AST). The AST will be designed to achieve three primary aims: (1) provide psycho-educational information on AS and its consequences, (2) present psycho-educational information on the relationship between AS and obesity-related health behavior correlates, and (3) offer concrete, evidence-based strategies to facilitate motivation to change their obesity-related lifestyle behaviors.

Detailed description: The primary goal of the research study is to investigate the efficacy of a brief, computer-delivered transdiagnostic intervention that addresses anxiety sensitivity to reduce emotional eating, eating expectancies, food cravings, binge eating, perceived barriers to engage in physical activity, anxiety/depressive symptoms, severity of daily fatigue and increase perceived benefits to engage in physical activity, exercise self-efficacy, willingness to use adaptive coping strategies, and perceived physical health functioning. To address this aim, the investigator's will implement a randomized controlled trial that will employ a longitudinal experimental design and involve five stages: (a) online pre-screener; (b) baseline survey consisting of a pre-intervention assessment (eligibility) and random assignment to a one-session computer-delivered intervention (Active versus Control); (c) 1-week follow-up survey; (d) 2-week follow-up survey; (e) 1-month follow-up survey.
