Objectives. Proper use of personal protective equipment (PPE) is essential for worker safety, but many employees fail to use it correctly due to limited knowledge, negative attitudes and low perceived control. This study assessed the effectiveness of a health belief model (HBM)-based educational intervention on PPE use among factory workers in Yasuj. Methods. This quasi-experimental study (2022–2023) randomly assigned 109 workers were to experimental (n = 56) and control (n = 53) groups. The intervention included six 60-min in-person sessions delivered by a researcher and an occupational health expert. Data were collected via an HBM-based questionnaire before and 2 months after the intervention. Statistical analyses included paired t tests, independent t tests and χ2 tests using SPSS version 27. Results. Pre-intervention assessments showed no significant differences between groups (p > 0.05). Post intervention, the experimental group demonstrated significant improvements in all HBM constructs – knowledge, attitudes, perceived susceptibility and severity, perceived benefits and barriers, self-efficacy, guidance for action – as well as PPE-related behavior (p = 0.001). Conclusion. HBM-based educational interventions effectively enhance PPE usage by improving knowledge, shaping positive attitudes and addressing perceived barriers and benefits. These findings support structured educational programs as a key strategy for promoting workplace health and safety.
