Purpose: The purpose of this study was to construct and test a hypothetical model of exercise behavior in patients with Heart Failure (HF) based on the Information-Motivation-Behavioral skills (IMB) model, and the IMB model including depression (IMBD).
Methods: Data collection was conducted from February 1 to March 15, 2019. A total of 306 patients who were diagnosed with HF and were receiving outpatient treatment at the D University hospital and S hospital located in B city were included in the final analysis. The collected data were analyzed using SPSS 24.0 and AMOS 25.0 program.
Results: The IMB model (x 2 /df=2.45, SRMR=.07, RMSEA=.07, GFI=.98, AGFI=.94, TLI=.93, CFI=.97) and IMBD model (x 2 /df=0.79, SRMR=.02, RMSEA=.003, GFI=.99, AGFI=.97, TLI=.98, CFI=.97) were a good fit for the data. In the exercise behavior IMB model, exercise behavior was explained by 55.1% by information, personal motivation, and behavioral skills. In the exercise behavior IMBD model, exercise behavior was explained by 60.4% by information, personal motivation, behavioral skills, and depression.
Conclusion: The IMBD model showed high predictive power of exercise behavior. Therefore, in order to improve HF patients’ exercise behavior, it is necessary to identify and manage patients who experience depression. The development and application of integrated interventions to provide appropriate information, motivation, and confidence in exercise can be an effective strategy in increasing exercise compliance, and ultimately contribute to improving the health outcomes of patients with HF.
