The present study aimed to determine the effect of lifestyle educational intervention based on the theory of planned behavior on promoting the quality of life of middle-aged women. The present quasi-experimental study examined 80 middle-aged women and randomly divided them into two groups (intervention and control). Data collection tools included the demographic information questionnaire, the Health Promoting Lifestyle Profile-II (HPLP-II), the 12-Item Short-Form Health Survey (SF-12), and the author-developed questionnaire based on constructs of the theory of planned behavior. Data were collected via WhatsApp twice (before and three months after the educational intervention). Five 45-minute training sessions were held for the intervention group and a 60-minute session for a family member regarding physical activity and spiritual growth over two months via WhatsApp. Data were analyzed using SPSS, and the results were considered significant at a statistical level (p < .05). The implementation of the educational intervention significantly increased the mean scores of quality of life, physical activity and spiritual growth, knowledge regarding physical activity and spiritual growth, attitude toward physical activity and spiritual growth, subjective norms toward spiritual growth, perceived behavioral control for physical activity, and behavioral intention to perform physical activity and spiritual growth in the intervention group in comparison with the control group. The educational intervention, which was designed based on constructs of the theory of planned behavior, was influential in promoting the lifestyles and quality of life of middle-aged women. Therefore, it is suggested to use the educational program of the present study in addition to other middle-age health care.
