title: Long-term effect of motivational interviewing on clinical and psychological outcomes and health-related quality of life in cardiac rehabilitation patients with poor motivation in Hong Kong: a randomized controlled trial.
abstract: OBJECTIVE
  To investigate the long-term effects of motivational interviewing on clinical outcomes, psychological outcomes, health-related quality of life among cardiac rehabilitation patients with poor motivation.
  
  
  METHODS
  A randomized controlled trial with blind data collectors.
  
  
  METHODS
  Cardiac rehabilitation centre.
  
  
  METHODS
  A total of 146 cardiac rehabilitation patients with poor motivation.
  
  
  METHODS
  All participants received usual care, including exercise and education, while those in the experimental group also received 10 sessions of motivational interviewing, each lasting 30-45 minutes.
  
  
  METHODS
  Clinical and psychological outcomes and health-related quality of life were assessed at baseline and at six, nine and 12 months for both groups.
  
  
  RESULTS
  There was no significant difference between the two groups at baseline on demographic and clinical outcomes except for monthly family income (p = 0.034). Patients in the experimental group had higher increases in health-related quality of life (SF-36) scores in bodily pain (88.7 SD 16.7 vs. 87.6 SD 18.7 at month 12, p = 0.044) and role limitation owing to emotional problems (86.9 SD 19.2 vs. 78.6 SD 21.8 at month 9, p = 0.019; 85.8 SD 18.9 vs. 76.9 SD 23.9 at month 12, p = 0.022). No statistically significant group difference was found among other outcomes.
  
  
  CONCLUSIONS
  The long-term effect of motivational interviewing on clinical and psychological outcomes and health-related quality of life in studied patients is limited.
