      heart failure patients.

AB  - BACKGROUND: Dyspnea is the most common and distressing symptom of heart failure 
      (HF). Evidence from empirical studies has shown that multiple factors apart from 
      pathophysiological changes may influence this symptom. PURPOSE: This study 
      explored the moderating effect of psychosocial factors between clinical 
      characteristics and dyspnea in patients with HF. To assess the potential effects 
      of cultural background, this study also compared differences in psychosocial 
      factor moderating effects between HF patients in Taiwan and the United States. 
      METHODS: We recruited patients with HF from outpatient clinics in Taiwan and the 
      United States. Data were collected at clinics and research centers. Dyspnea was 
      measured using the modified pulmonary function status and dyspnea questionnaire. 
      Psychosocial factors considered were depression, anxiety, perceived control, and 
      perceived social support. These factors were measured using the Brief Symptom 
      Inventory, Revised Control Attitudes Scale, and Multidimensional Scale of Social 
      Support Scale, respectively. Multiple regressions with interaction effect 
      analysis tested the moderator effects across these two groups. RESULTS: 
      Ninety-seven Taiwanese (mean age = 66.2 +/- 12.1 years; 76% male; 28% NYHA [New 
      York Heart Association] III/IV) and 96 American (mean age = 61.6 +/- 11.7 years; 
      74% male; 42% NYHA III/IV) patients participated. In Taiwanese patients, only 
      perceived social support (B = .08, p = .034) moderated the relationship between 
      clinical variables and dyspnea. In American patients, depression (B = .75, p = 
      .028) and anxiety (B = .85, p = .041) were moderators of the relationship between 
      clinical status and dyspnea severity. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: 
      Depression, anxiety, and perceived social support moderated the relationship of 
      clinical characteristics with dyspnea in Taiwanese and American HF patients, 
      respectively. Attention to these psychosocial factors may improve dyspnea status 
      in HF patients. Symptom management should include a focus on patients' 
      psychological distress and social perspectives.
