This study is to predict adults' health-related quality of life through a combination of subordinate variables of the planned behavior theory and the stages of change in physical activities. Participants were 318 adults (the pre-stage of planning: 16, the planning stage: 43, preparation stage: 87, behavior stage: 52, maintenance stage: 1201; and mean age = 35.4 year-old). In order to measure psychological variables, current exercise stage and physical activity levels of the participants, attitude, subjective norms, questionnaire papers of perceived behavioral control and stages of exercise change were applied. This study showed that there was a statistically significant difference in all variables in the stages of change in physical activities. The result of hierarchial regression analyses revealed that perceived behavioral control was at 33%, 18% for subjective norms and 16% for attitude in terms of subordinate variables of the planned behavior theory in stages of exercise change. Meanwhile, the result showed that perceived behavioral control was at 23%, 19% for attitude and 11% for stages of exercise change in terms of health-related quality of life. This study indicates that integrative studies on psychological variables will develop into a prominent part of sports science.
