A Web-Based Intervention for Insufficiently Active College Students: Feasibility and Preliminary Efficacy

Abstract

Background: One third of college students do not achieve aerobic activity levels recommended for physical and mental health. The web-based “I Can Be Active!” intervention was designed to help college students increase their physical activity. The intervention was grounded in the Multi-Process Action Control (M-PAC) framework which emphasizes translating intention into sustainable action. Objective: The primary purpose was to evaluate the feasibility of the intervention with insufficiently active young adult college students. The secondary purposes were to describe the preliminary effects of the intervention on: (1) the M-PAC constructs and (2) physical activity. Methods: Twenty-one college students, ages 18 to 24, were enrolled in the pre-post quasi-experimental study to test the 8-week intervention during Spring 2021. Data were collected via self-report questionnaires, web-analytics, and interviews. Feasibility outcomes included recruitment, retention, acceptability, practicality, and implementation. Preliminary efficacy outcomes were self-report M-PAC constructs and physical activity. Data analyses included descriptive statistics, t tests, Wilcoxon signed rank tests, Hedge’s g, and thematic analysis. Results: Recruitment and retention rates were 70% and 71%, respectively. Participants reacted positively to the program, content, and features, except the manual entry step tracker and private social media group. Positive trends and significant increases were found in the regulatory and reflexive M-PAC constructs (self-regulation, habit, and identity) and physical activity. Conclusions: Findings support the feasibility and preliminary effects of the intervention for insufficiently active college students and highlight implications for intervention refinement. Future research will test intervention effectiveness using a randomized controlled trial with a larger diverse sample of college students.

Reporting Targeted Interventions

“…When reporting targeted interventions, authors should provide information in the introduction and background about why there is a need to target interventions to this specific population. For example, in the paper by Hartson and colleagues in this issue, 1 the authors developed a physical activity intervention targeting insufficiently active college students. Young adults (the primary demographic among college students) are likely to be interested in different intervention content and intervention delivery modalities than middle-aged and older adults.…”
