Effects of Applying the Planned Behavior Theory and Feedback on Noise Protection Behaviors among at-risk Personnel in Hospital, Suphanburi Province

Abstract

The rising prevalence of noise-induced hearing loss among hospital personnel requires effective and sustainable prevention strategies. This study aimed to examine the effects of a program that incorporated the theory of planned behavior and provided feedback on preventing noise hazards among at-risk personnel in a hospital located in Suphanburi province. The research utilized a two-group pretest-posttest quasi-experimental design, comprising a total of 104 participants—52 in the experimental group and 52 in the comparison group. Descriptive statistics and t-tests were employed for data analysis. The study found that after the program, the experimental group had significantly higher average scores in several areas, including attitudes, influences on behavior, motivation to perform specific behaviors, and actions related to noise hazard prevention, compared to their pre-program scores. When comparing the experimental group to the control group, the experimental group also showed significantly higher average scores in attitudes, motivation to engage in behaviors, perceived ability, behavioral intention, and noise hazard prevention behaviors. These findings of this study suggest that hospitals can effectively integrate this program with existing safety measures to enhance the prevention of occupational noise hazards among hospital personnel.
