Situational Factors on Use of Hearing Protection This three-item scale included two subscales: choice of HPDs and fire service organizational support for health. Choice of HPDs was measured by level of agreement with a single statement: “At your fire department, you have a choice of different types of hearing protection.” Fire service organizational support for health was measured by two items: “Your fire service organization is generally concerned about your health and well-being,” and “Your fire service organization is committed to improving yourhealthand well-being.” All situational factors weremeasured on a 5-point Likert scale (1 0 strongly disagree, 5 0 strongly agree).
