Thirdhand Smoke Knowledge, Attitudes, and Behavior: Development of Reliable and Valid Self-report Measures.

Numerous scales have been vetted as reliable and valid measures for assessing secondhand smoke-related knowledge, attitudes, and behaviors. Currently, standard measures of thirdhand smoke knowledge, attitudes, and behaviors are not available. This study tested three thirdhand smoke scales to fill this gap. The present findings provide tobacco control advocates, scholars, and practitioners tools for assessing knowledge, attitudes, and behaviors related to thirdhand smoke. This information is critical to development, implementation, and evaluation of novel tobacco control strategies.
