Predictors of hearing protection use among workers: implications for training programs.

In this study, we used the conceptual Health Promotion Model to identify predictors of hearing protection use among blue-collar workers (N = 504). The strongest predictors were self-efficacy, benefits, value, and barriers. Items in the barriers scale were most strongly correlated with use and had the greatest potential for change. Therefore, items from this scale are being used as the primary basis for development of a training intervention program.
