Meta-Analysis of Implementation Intentions Interventions in Promoting Physical Activity among University Students
S. Peng, A. T. Othman, et al.
This meta-analysis, conducted by Sanying Peng, Ahmad Tajuddin Othman, Ahmad Zamri Khairani, Zhuang Zhou, Xiaogang Zhou, Fang Yuan, and Jinghong Liang, found that implementation intentions significantly increased physical activity among university students (SMD = 0.31, 95% CI: 0.12–0.50). Effects were larger in studies after 2013, among inactive students, with reinforcement or action planning, and in interventions shorter than six weeks; integrating IIs with e‑health and individualized, multifaceted models shows promise for sustainable on‑campus promotion.
