Purpose: The purpose of this research was to study the effectiveness of the IMB Educational Health Promotion (IMBEHP) video for improving quality of life, health risk awareness, and health promotion among Chiang Mai University (CMU) personnel. Methods: This research was a quasi-experimental study with a 1-group pre-posttest design. The sample group included 528 CMU personnel who worked at the university between June 2020 and December 2021. Data collection was conducted before and after participants watched the IMB health promotion video. Results: After watching the video, the participants’ quality of life scores were at a medium level. Moreover, physical health, mental health, social relations, and total quality of life score measures showed statistically significant differences between before and after viewing, at P < .05. The mean total for quality of life increased from the prior intervention implementation. Understanding of health risks also increased after watching the video, and the levels of health risk increased as follows: low level of health risk increased to 343 (64.96%), followed by medium and high health risk, at 21.78% (n = 115) and 10.04% (n = 53), respectively. Lastly, awareness about nutrition was statistically significant at .05. Conclusions: The results of this study demonstrate the efficacy of video in educating, motivating, and developing health-promoting skills among this population. After watching the video, CMU personnel increased their awareness of chronic disease risk factors, health promotion practice, illnesses prevention, healthy behaviors, and improvement of quality of life.
