Objective: To evaluate the motivational effect of the Project WebHealth study procedures and intervention components on weight-related health behavior changes in male and female college students. %26lt;br%26gt;Design: Process evaluation. %26lt;br%26gt;Setting: Eight universities in the United States. %26lt;br%26gt;Participants: Project WebHealth participants (n = 653; 29% men). %26lt;br%26gt;Main Outcome Measures: Participants rated motivational effects of study procedures and intervention components. Participants were grouped into outcome-based health behavior categories based on achievement of desired targets for fruit and vegetable intake, physical activity, and/or body weight. %26lt;br%26gt;Analysis: Differences in motivation from each procedure and component were analyzed by gender-and outcome-based health behavior category. %26lt;br%26gt;Results: Women were generally more motivated than men. Compared to those who did not meet any target health behaviors, men with improved health outcomes (68%) were significantly more motivated by the skills to fuel the body lesson, goal setting, and research snippets. Their female counterparts (63%) were significantly more motivated by the lessons on body size and eating enjoyment, and by the suggested weekly activities. %26lt;br%26gt;Conclusions and Implications: Specific study procedures and components of Project WebHealth motivated study participants to improve their weight-related health behaviors, and they differed by gender. Findings support the need for gender-tailored interventions in this population.
