Factors associated with the performance of Dengue Fever Prevention and Control among Village Health Volunteers, Nakhon Pathom Province

Abstract

This cross-sectional analytical study was aimed at examining the performance level of Village Health Volunteers (VHVs) in dengue fever (DF) prevention and control, as well as investigating the factors related to their performance in Nakhon Pathom Province. The study employed the theoretical frameworks of the protection motivation theory (PMT) and Herzberg’s two-factor theory. The sample consisted of 350 VHVs with at least one year of work experience, selected using multi-stage random sampling. Data were collected using a questionnaire. Data were collected during July – August 2025 and analyzed by descriptive statistics and multiple linear regression analysis.

The results indicated that most VHVs were female (83.1%), with a mean age of 58 years and an average work experience of 13 years. High levels of performance were observed across disease surveillance, control, and prevention at 69.14%, 66.29%, and 64%, respectively. Similarly, knowledge of Dengue Fever, motivation, and work-related hygiene factors were also reported at high levels at 89.14%, 85.71%, and 92%, respectively. The factors significantly associated with performance included work-related hygiene factors, self-efficacy, and response efficacy, with standardized regression coefficients (β) of 0.294, 0.255, and -0.159, respectively. All identified factors collectively explained 28.3% of the variance in performance (Adjusted R² = 0.283).

The results of this study suggest that for the enhancement of the performance of VHVs, systemic support (hygiene factors) and building self-efficacy are more crucial than merely providing knowledge. It is therefore recommended that the relevant agencies develop policies that are focused on resource allocation, conduct practical workshops to enhance skills and build confidence, and establish appropriate motivation systems to maintain VHV morale and ensure sustainable performance.
