Self-care Behavior Based on Integrated Behavioral Model in Patients With Atrial Fibrillation: A Structural Equation Modeling Approach.

BACKGROUND

There is limited research exploring the behavioral intentions, beliefs, and application of theoretical models in relation to self-care in patients with atrial fibrillation (AF).

OBJECTIVE

This study aimed to identify the factors that influence self-care behavior in patients with AF.

METHODS

The study used an integrated behavioral model and collected data from 216 patients diagnosed with AF. Data were analyzed using SPSS 24.0 and AMOS/WIN 24.0 to verify the fit of the hypothesis model, confirm factor analysis, and the validity of the hypothesis itself.

RESULTS

Self-care behavioral intention (β = 0.433, < .001) and habit (β = 0.395, = .005) had a significant direct effect, while instrumental attitude (β = 0.077, = .045), injunctive norm (β = 0.084, = .037), and self-efficacy (β = 0.249, = .011) had a significant indirect effect on self-care behavior, explaining 64.4% of the variance.

CONCLUSION

The final model validated the factors that impact self-care behavior in patients with AF, highlighting the importance of fostering positive recognition of instrumental attitude, bolstering social influence and self-efficacy through significant individuals to improve self-care behavior. It is recommended to create an intervention program that encourages intentions and motivations for self-care behavior and incorporates tactics to make self-care behavior a habit. The study's path diagram can serve as a conceptual framework for designing strategies to enhance self-care behavior in patients with AF.
