Physical activity has numerous positive and psychological benefits. Therefore, a physically active lifestyle benefits both the individual and the society. Nevertheless, many people drop out from their sport or exercise regimen. In this inquiry three motivational factors in exercise adherence, including predisposing, enabling, and reinforcing factors, were studied from a cross-cultural perspective. A total of 235 male (n=151) and female (n=84) volunteers (mean age=21.4 ± 2.6 years) from Hong Kong (n=112) and United Kingdom (n=123) completed an exercise habits inventory and the Physical Activity Adherence Questionnaire (PAAQ). All participants were physically active, of whom 132 have once quit a sport/exercise in the past whereas 103 never quit. Results revealed that differences exist in predisposing and enabling motivational components of exercise adherence in both cross-cultural and gender comparison studies. Participants who quit a sport or exercise report lesser reinforcing experiences than those who never abandoned an adopted sport or exercise. It is concluded that reinforcing factors play a crucial role in the long term maintenance of a sport or exercise and that both cultural and gender differences need to be taken into serious consideration in the course of facilitation of various exercise/sport behaviours.[Copyright © 2003 Department of Physical Education, Hong Kong Baptist University.]
