title: [Psychological factors of adopting and maintaining physical activity for individuals with hypertension in a community].
abstract: OBJECTIVE
  To examine the impact of psychosocial factors on physical activity, so as to provide guidance for the development of an effective physical activity intervention program for individuals with hypertension.
  
  
  METHODS
  This study used a baseline data from an intervention study on regular physical activity among hypertensive individuals. A multi-stage, stratified random sampling was utilized and finally 12 communities from 6 urban districts were chosen. Questionnaires were administrated through face-to-face interviews. A total of 586 participants were recruited and finally 559 completed the interviews with the response rate as 95.4%. Descriptive statistics and Cronbach's α coefficients were used to test the reliability. General Linear Model analysis was used to analyze the relationship between stages of physical activity and psychological factors.
  
  
  RESULTS
  Psychosocial measures on physical activity demonstrated good reliability with Cronbach α coefficient from 0.7 to 0.9. The scores for each psychological measures increased by increasing the scores of stages of physical activity. General Linear Model analysis revealed self-efficacy (β = 0.379) while enjoyment of physical activity (β = 0.234) was significantly correlated with physical activity (P < 0.05). The behavioral processes and family support marginally increased the physically activity (β = 0.069 for behavioral processes and β = 0.163 for family support, P < 0.10).
  
  
  CONCLUSIONS
  Our findings were informative for the development of community-based intervention programs on physical activity among hypertensive individuals. It indicated that physical activity intervention programs should be psychosocial theory-based, especially increasing their self-confidence and enjoyment, as well as with family support, in order to adopt and maintain the physical activities.
