t lifestyle” were the least common reasons.

4. DISCUSSION

We investigated predictors of the intention to undergo specific health guidance using the HBM components. Perceived threat, net benefit, perceived severity, perceived benefit, and perceived barriers, were associated with intention, and net benefit was a stronger predictor than perceived benefit and perceived barriers.

Our data indicate that net benefit was a stronger predictor of intention than were perceived benefit and perceived barriers. Other studies have investigated perceived benefit/barriers to participation in health-promotion programs [9-12,14,16,18,19]. Some of these analyzed the correlation between benefit/barriers and participation without integrating the two components [12, 17-19]. Thus, there is little information regarding net benefit. However, some studies of health behavior have examined decisional balance [21,22]. These suggested that individuals in the action/maintenance stage perceived more pros (benefits) than cons (barriers), and those in the pre-contemplation stage perceived more cons than pros [21,22]. In this study, people who perceived more benefit than barriers had a greater intention to participate, so our finding is consistent these studies [21,22]. This finding suggests the importance of the combined influence of perceived benefit and perceived barriers, demonstrating that both elevating perceived benefit and reducing perceived barriers are important. Such a change may increase the difference between perceived benefit and perceived barriers and thereby improve participation rates.

We also investigated the reasons that participants did not undergo specific health guidance. The most common answers were “can’t take time” and “don’t know contents.” Many previous studies have reported that time was the most important barrier to participation in WHP programs [9-14]. However, Middlestadt and colleagues reported that individuals with high intention to participate in a worksite wellness program regarded programs that take place outside of work hours or during work hours and at a convenient location as facilitators of participation [12]. Thus, time is a particularly important factor because it can represent both a benefit of and a barrier to WHP programs. Few studies have examined the “don’t know contents” rationale, but Fletcher and colleagues reported that a lack of instructions was one of the barriers to participation in a physical activity program [18]. Therefore, health insurance providers should explain the contents of specific health guidance to patients. These findings will be useful for developing intervention programs to improve the rate of specific health guidance participation.

Perceived threat was a significant predictor of intention, but was weaker than net benefit. This is thought to be due to the fact that perceived susceptibility was not significantly correlated with intention. Some previous studies reported that perceived susceptibility and perceived severity were significant predictors of intention/ behavior, whereas others have not found them to be predictors [22-28]. Therefore, whether perceived threat, perceived severity, and perceived susceptibility correlate with the likelihood of undergoing specific health guidance should be investigated in future research.

The present study has some limitations. First, intention was used, and whether those intentions translate into actually undergoing specific health guidance is uncertain. Second, a self-reported questionnaire was used, and the reliability of responses should be examined. Third, confounders related to the intention to undergo specific health guidance such as lifestyle, health status, working time, and support by management were not investigated and should be a focus of future research.

The strength of this study lies in the fact that we analyzed not only the four subcomponents of the HBM, but also perceived threat and net benefit; these latter two factors explained 39.1% of the variation. Therefore, the HBM can sufficiently predict intention to undergo specific health guidance.

5. CONCLUSIONS

The present study explored the predictors of intention of Japanese workers to undergo specific health guidance using the Health Belief Model. The model using four subcomponents (Model 1) and that using the two main components (perceived threat and net benefit; Model 2) both predicted intention; however, net benefit was a stronger predictor of intention than were perceived benefit or perceived barriers. Therefore, our data suggest that net benefit should be used in analyses based on the HBM, and it is important to both increase benefit and decrease barriers to improve participation in health-promotion programs.
