Objective:
Cardiovascular disease (CVD) is a leading cause of mortality. This study aimed to develop and psychometrically evaluate the Cardiovascular Health Beliefs Scale (CHBS) to assess CVD-related health beliefs.
Methods:
A cross-sectional methodological design was utilized in two phases. Phase 1 (n = 150) focused on item generation and exploratory factor analysis. Phase 2 (n = 531) involved confirmatory factor analysis. Data were collected via face-to-face interviews using the newly developed CHBS and the Brief Symptom Inventory (BSI) General Severity Index to test construct validity.
Results:
The CHBS supported an acceptable six-factor structure: perceived susceptibility, perceived severity, health motivation, perceived benefits, perceived barriers, and self-efficacy. Cronbach's alpha coefficients ranged from .70 to .84, demonstrating adequate internal consistency.
Conclusion:
The CHBS demonstrated acceptable validity and reliability as a measurement tool. It enables nurses and healthcare professionals to assess risk behaviors and implement culturally congruent, targeted preventive interventions for cardiovascular care within the Turkish population.
