Objective <p>This study analyzes the mediating role of perceived benefits and barriers in the relationship between social support and the utilization of Non-Communicable Disease (NCD) Integrated Health Service Posts (IHSP) among industrial workers in Indonesia. The goal is to provide strong empirical evidence to inform the development of more effective, ecosystem-based occupational health interventions by understanding the perceptual mechanisms through which social support influences the uptake of health services in this high-risk population.</p> Description of results <p>The study found that social support significantly increased the perception of benefits (β = 0.869) while simultaneously lowering perceived barriers (β = -0.613). Perceived benefits strongly predicted the use of NCD services (β = 0.612), while the influence of perceived barriers on service use was statistically insignificant. These results confirm the presence of asymmetric mediation, where the influence of social support on service utilization is predominantly channelled through strengthening the perception of benefits rather than simply reducing barriers. This implies that social support functions by resolving barriers at an “upstream” level, making the enhanced perception of benefits the primary driver for service uptake.</p>
