  Purpose

The purpose of this study is to implement a peer modeling intervention to improve self-efficacy and aerobic fitness in obese youth. A total of 40 obese (defined as Body Mass Index greater than the 95th percentile for age and gender) youth will participate in this study.

Primary Outcome Measures:
  • Physiological measure: Aerobic Fitness [ Time Frame: Baseline (day 1) and follow-up (day 7) ] [ Designated as safety issue: No ]
    Changes in aerobic fitness from baseline (day 1) to follow-up (day 7) will be evaluated by a trained exercise physiologist using a standardized, maximal incremental exercise protocol (Modified Bruce protocol) on a treadmill. Expired gases will be analyzed using a metabolic cart (Cosmed Quark B2 cardiopulmonary testing, Image Monitoring). Peak oxygen consumption (Peak VO2) will be determined by taking the highest values during a 15 second period and expressed in absolute (l/min) and relative (ml/kg/min) units with the latter unit used for subsequent analysis.

  • Psychological: Self-Efficacy [ Time Frame: Baseline (day 1) and follow-up (day 7) ] [ Designated as safety issue: No ]
    Changes in self-efficacy from baseline (day 1) to follow-up (day 7) will be evaluated by an 18-item Self-Efficacy Scale (adapted from McAuley & Milhalko, 1998) to evaluate participants' confidence to successfully perform increasing intensities and durations of physical activity.


Secondary Outcome Measures:
  • Changes in variability (standard deviation) [ Time Frame: Baseline (day 1) and follow-up (day 7) ] [ Designated as safety issue: No ]
    Changes in variability (standard deviation) in the aerobic fitness and self-efficacy data will be analyzed using statistical software.

Arms Assigned Interventions
Experimental: Peer modeling
Participants watch a video geared to increase confidence in ability to preform fitness test. Male participants will watch a video of a male adolescent completing the fitness test and talking about coping mechanisms used to preform to the best of his ability. Female participants will watch a video of a female adolescent completing the fitness test and talking about coping mechanisms used to preform to the best of her ability.
Behavioral: Peer Modeling
Participants watch a video of an adolescent completing the fitness test and explaining coping mechanisms to preform the test well.
Other Names:
  • Observational Learning
  • Coping Model
Active Comparator: Control
Participants watch a video unrelated to the fitness test and self-efficacy. The video depicts healthy food and nutrition options.
Behavioral: Control
watching a video unrelated to the fitness test and self-efficacy
Other Names:
  • Contact control
  • Active control
