Brief Summary

Keywords

secondhand smoke; exposure; health belief model

Outcome Measures

Primary Outcomes (1)

• Health belief model scale for prevention behaviors of secondhand smoke exposure (HBM-SHS)

  The 35-item scale, scored on a five-point Likert scale from "Strongly Disagree (1)" to "Strongly Agree (5)," assesses six subdimensions: "perceived susceptibility," "perceived seriousness," "perceived benefits," "perceived barriers," "self-efficacy," and "behavioral cues." Items on "perceived susceptibility" and "perceived barriers" are reverse coded. Scores range from 35 to 175, with higher scores indicating stronger health beliefs about SHS exposure and greater beliefs in each subdimension.
