Survey Questionnaire
Content of the questionnaire was based on prior research
that determined the predictors of hearing protection use
among factory and construction workers (Lusk, Ronis,
Kerr, & Attwood, 1994; Lusk, Kerr, et al., 1999). The most
important predictors from the Health Promotion Model
(Pender, 1987) were:
• perceived benefits and perceived barriers to use of
hearing protection
• perceived self-efficacy in the use of hearing protection
• situational factors and interpersonal support for use
of hearing protection
