Administrative Factors Affecting the Surveillance, Prevention, and Control of Dengue Fever by Community Leaders in Chang Klang District, Nakhon Si Thammarat Province

Abstract

This research was a cross-sectional study aimed to 1) investigate the level of dengue fever surveillance, prevention, and control practices and 2) identify the factors influencing the performance of dengue fever surveillance, preventing and control activities among community leaders in Chang Klang District, Nakhon Si Thammarat Province. The population consisted of 240 community leaders. The sample size, calculated to be 176 participants, was selected using simple random sampling. Data were collected during April 1–30, 2025. The research instrument was a questionnaire validated by three experts, with an index of item-objective congruence (IOC) ranging from .67 to 1.00. Cronbach’s alpha coefficient were .97 for the administrative factors scale and .96 for the dengue fever surveillance, prevention, and control performance scale. Data were analyzed using descriptive statistics and stepwise multiple regression. The research findings revealed that:

1. The overall level of administrative factors was moderate. Considering each aspect, personnel and work motivation factors were at a high level, whereas time for implementation, management methods, materials and equipment, and budget were at moderate level. The overall performance of dengue fever surveillance, prevention, and control was high level.

2. The factors influencing the performance of dengue fever surveillance, prevention, and control were found to include time for implementation, personnel, work motivation, and management methods, which together could predict 75.1% of the variance (_adjR² = .751).

Therefore, it is recommended to support personnel factors and enhance work motivation among community leaders, as well as to promote adequate time management, effective management methods, sufficient materials and equipment, and budget allocation. In addition, community leaders should be encouraged to participate in every step of the process, ensuring awareness of operational procedures and related policies.
