摘要

Objective

This study aimed to development of passıve exposure to tobacco smoke attıtude scale for adults as a valid and reliable measurement tool and to conduct its psychometric evaluation.

Method

Designed as a methodological study, data were collected from 555 adult volunteers between March and June 2024. Instruments included a socio-demographic questionnaire and the draft Passive Exposure to Tobacco Smoke Attitude Scale for Adults, developed through literature review. Item pool creation was followed by content validity assessment via expert review (n=11), yielding a Content Validity Index of 0.98. Psychometric properties were analyzed using Jamovi 2.6.26, including exploratory and confirmatory factor analyses, known-groups validity analyse and reliability tests.

Results

The scale consists of 18 items across two factors with eigenvalues >1, supported by scree plot analysis. Cronbach’s alpha was 0.94 for the negative attitude subscale, 0.81 for the positive attitude subscale, and 0.90 overall. The Kaiser-Meyer-Olkin value was 0.93, and Bartlett’s test was significant. The total explained variance was 58.6%. In confirmatory factor analysis, most model fit indices showed excellent fit. The scale significantly distinguished the attitudes of tobacco users and non-users toward passive exposure.

Conclusion

The passive exposure to tobacco smoke attitude scale for adults demonstrates strong validity and reliability, making it suitable for assessing adult attitudes toward passive exposure and exploring their associations with other variables. Clinicians or public health professionals can use passive exposure to tobacco smoke attitude scale to identify high-risk peoples who may be more permissive toward secondhand smoke, allowing for tailored counseling that addresses specific cognitive biases.
