Measure Description: Knowledge about hearing conservation was assessed with 16 items in the the Knowledge, Attitudes, and Behaviors Questionnaire (KAB; Saunders et al., 2014). It is a validated questionnaire that assesses knowledge about and attitudes toward hearing and hearing loss prevention. The Knowledge scale is scored as a percent correct, with a higher score indicating more knowledge.

Measure Description: Perceived Susceptibility is a construct from the Health Belief Model defined as an individual's assessment of the risk of acquiring a condition. Here it assesses the extent to which the individual feels vulnerable to hearing loss. Perceived Susceptibility was assessed with 5 items in the Knowledge, Attitudes, and Behaviors Questionnaire. Scores range from -50 to +50. A higher score indicates greater perceived susceptibility.

Measure Description: Perceived Severity is a construct from the Health Belief Model defined as an individual's assessment of the seriousness of a condition. Here it assesses the extent to which the individual believes that a hearing loss would have negative consequences. Perceived Severity was assessed with 3 items in the Knowledge, Attitudes, and Behaviors Questionnaire. Scores range from -50 to +50. A higher score indicates greater perceived severity.

Measure Description: Perceived Benefit is a construct from the Health Belief Model defined as an individual's assessment of the positive consequences of adopting a health behavior. Here that is the belief that hearing well is important. Perceived Benefit was assessed with 7 items in the Knowledge, Attitudes, and Behaviors Questionnaire. Scores range from -50 to +50. A higher score indicates greater perceived benefit.

Measure Description: Perceived Barriers is a Health Belief Model construct defined as an individual's assessment of the influences that discourage adoption of a health behavior. Here it assesses the extent to which the individual perceives protecting hearing to be negative. Perceived Barriers was assessed with 3 items in the Knowledge, Attitudes, and Behaviors Questionnaire. Scores range from -50 to +50. A higher score indicates fewer perceived barriers.

Measure Description: Perceived Self-efficacy is a Health Belief Model construct defined as an individual's assessment of their ability to successfully adopt a health behavior. Here it is the extent to which the individual believes they have the capacity to their protect hearing. It was assessed with 4 items in the Knowledge, Attitudes, and Behaviors Questionnaire. Scores range from -50 to +50. A higher score indicates greater perceived self-efficacy.

Measure Description: Cues to action is a Health Belief Model construct defined as external influences that promote a health behavior (e.g. symptoms, media communications, or information from a healthcare provider). Here it refers to prompts from others about protecting hearing. Cues to action was assessed with 2 items in the Knowledge, Attitudes, and Behaviors Questionnaire. Scores range from -50 to +50. A higher score indicates more cues to action.

Title Change in Perceived Susceptibility Score
Hide Description Perceived Susceptibility is a construct from the Health Belief Model defined as an individual's assessment of the risk of acquiring a condition. In the current study it assesses the extent to which the individual feels vulnerable to hearing loss. Perceived Susceptibility was assessed with 5 items in the Knowledge, Attitudes, and Behaviors Questionnaire (KAB; Saunders et al., 2014). Scores for each item are averaged and transformed onto a scale ranging from -50 to +50, with a higher score indicating greater perceived susceptibility, which according to the Health Belief Model will increase an individual's likelihood of engaging in a health behavior. Change in Perceived Susceptibility was computed as the difference between baseline and 1-month follow-up scores, with a higher score indicating greater perceived susceptibility at follow-up.

Perceived Self-efficacy was assessed with 4 items in the Knowledge, Attitudes, and Behaviors Questionnaire (KAB; Saunders et al., 2014). Scores for each item are averaged and transformed onto a scale ranging from -50 to +50, with a higher score indicating greater perceived self-efficacy, which according to the Health Belief Model, will increase an individual's likelihood of engaging in a health behavior.
