ABSTRACT
Purpose: This study examined the feasibility of Project Mentor, a mentoring program based on self-determination theory (SDT) for youth classified as overweight or obese. Methods: In Study 1, youth (N = 23) ranging from 12-18 years of age were randomly assigned to a mentoring intervention or wait-list control condition. Study 2 served as a replication sample and consisted of N = 38 youth who participated in the mentoring program. As part of a process evaluation, attendance and exercise heart rate were monitored to assess whether participants exercised at a moderate-to-vigorous level as intended. Mentees also rated whether mentors created a need-supportive environment. For outcome evaluation, basic need satisfaction, behavioral regulation, fitness, and body composition were assessed at pre, post, and follow-up. Results: Across both studies, participants attended over 80% of the exercise sessions and exercised at a moderate to vigorous intensity level. Mentees also perceived that mentors created a need-supportive environment. Post-test and follow-up basic need scores were higher than baseline values and autonomous motivation increased for mentoring program participants. Effect sizes were generally moderate to large in magnitude based on partial eta-squared and Cohen d. Aerobic fitness (i.e., Vo2peak) showed a moderate to large increase at post-test that was partially maintained at follow-up. Body composition changes were nonsignificant and small in magnitude. Participants in the wait-list control reported showed small changes or decreases across SDT related constructs, fitness, and body composition across both studies. Conclusions: Results across both studies support the feasibility of a mentoring program focused on CARE (competence, autonomy, relatedness, and enjoyment).
