In this study, the Health Promotion Model (HPM) was used as the basis
for a structural equation model of male and female blue collar workers
' self-reported use of hearing protection devices (HPDs). Overall use
did not differ by gender; in addition, self-efficacy and barriers to u
se of HPDs were the two best predictors of this behavior for both men
and women. Despite the similarities in HPD use and the most important
predictors of that use between men and women, the predictive models di
ffered by gender in several ways. Significant predictors of use among
men also included age and value of use of HPDs. For women, ethnic stat
us and plant site were additional significant predictors of use. Becau
se the influences of plant site and gender on self-reported use of HPD
s could not be separated in this study, further research should addres
s worksite culture and assess differences by gender. Knowledge of thes
e differences will aid development of more effective interventions and
may increase the use of hearing protection.
