Predictive Factors for Perceived Self-Efficacy in First Aid for Acute Coronary Syndrome among Village Health Volunteers

Abstract

This study employed a predictive correlational research design with a cross-sectional data collection approach to examine perceived self-efficacy in providing first aid for acute coronary syndrome (ACS) among village health volunteers (VHVs). A sample of 150 VHVs participated in the study. The instrument used was a questionnaire measuring perceived self-efficacy in providing first aid, yielding an overall Cronbach's alpha coefficient of .934. Subscale reliability coefficients were as follows: perceived susceptibility = .954, perceived severity = .970, perceived benefits = .965, perceived barriers = .942, cues to action = .884, initial symptom assessment = .921, calling the 1669 emergency hotline = .949, cardiopulmonary resuscitation (CPR) = .948, and automated external defibrillator (AED) use = .933. The four-dimension perceived self-efficacy scale (initial symptom assessment, calling 1669, CPR, and AED use) had an overall reliability of .884. Data were analyzed using descriptive statistics, Pearson's product-moment correlation, and multiple regression analysis. The results showed that village health volunteers' perceived self-efficacy in providing first aid for individuals with acute coronary syndrome accounted for 44.57% of the maximum possible score. Five factors—perceived susceptibility (β = .365), cues to action (β = .365), perceived benefits (β = .359), perceived barriers (β = -.147), and prior first-aid training (β = .139) jointly predicted perceived self-efficacy in providing first aid, accounting for 56.80% of the variance (R² = .568, Adjusted R² = .553, F(5, 144) = 37.816, p < .001). Based on these findings, training programs should be developed to strengthen perceived susceptibility and cues to action in order to effectively enhance VHVs' perceived self-efficacy in providing first aid.
