Background:

Fatigue makes daily tasks difficult for patients with heart failure (HF); however, its impact on self-care has not been reported. In addition, self-efficacy, self-care confidence, and perceived control are psychological determinants of self-care in patients with HF. The mechanisms by which these cognitive aspects influence self-care have not been fully investigated.

Aim:

The aim in this study was to determine whether perceived control mediates the relationship between fatigue and self-care in patients with HF.

Methods:

We conducted a secondary analysis (n = 165) of a cross-sectional, observational study in which patients were enrolled between February and August 2018 in Japan. We used the Brief Fatigue Inventory to measure fatigue; the Self-care of Heart Failure Index for self-care maintenance, management, and confidence; and the Control Attitude Scale Revised for perceived control. The PROCESS macro was used to assess mediation.

Results:

Fatigue had no direct effect on self-care maintenance, management, or confidence (effect coefficient [ c ] = 0.410; 95% confidence interval [CI], −1.039 to 1.858, c  = 1.594; 95% CI, −0.412 to 3.601, c  = 0.478; 95% CI, −1.041 to 1.997). There was, however, an indirect pathway between fatigue and self-care maintenance, management, and confidence through perceived control ( a * b  = −0.395; 95% CI, −0.936 to −0.040, a * b  = −0.749; 95% CI, −1.574 to −0.090, a * b  = −1.064; 95% CI, −2.086 to −0.181).

Conclusions:

Perceived control mediates the association between fatigue and self-care, improving perceived control as a key component to reduce the impact of fatigue on self-care.

AIMS: Fatigue, a distressing symptom in patients with heart failure (HF), is associated with progress and health outcomes. Fatigue has been identified as having multidimensions, but a few studies have used a multidimensional fatigue scale. Many factors related to HF, including physical, psychological, and situational factors, may impact fatigue. However, there is limited knowledge about how these HF-related factors are associated with multidimensional fatigue in outpatients with HF in Japan. The aim of this study was to identify HF-related factors [physical; clinical characteristics, New York Heart Association (NYHA) functional class and physical function, psychological; depressive symptoms and anxiety, situational; health literacy and perceived control] associated with the five dimensions of fatigue in outpatients with HF. METHODS AND RESULTS: Outpatients with HF (N = 165, mean age = 69.5 years, 78.8% male) completed the survey and physical assessment of gait speed. Fatigue was assessed using five dimensions of the Multidimensional Fatigue Inventory-20. Multiple linear regression analysis was conducted for each dimension of fatigue. General fatigue was predicted by age, NYHA, and perceived control. Physical fatigue was predicted by NYHA, depressive symptoms, and perceived control. Reduced activity was predicted by NYHA, gait speed, depressive symptoms, communicative health literacy, and critical health literacy. The reduced motivation was predicted by depressive symptoms and perceived control. Mental fatigue was predicted by depressive symptoms. CONCLUSION: Different factors were significantly associated with each fatigue dimension. Further research is needed to alleviate fatigue in patients with HF.
