BACKGROUND: Prevention of smoking is very important at a young age and during the studentperiod. Because of the lack of a questionnaire based on the prevention of smoking behavior,this study was conducted to design and standardize a tool according to the protection motivationtheory (PMT).MATERIALS AND METHODS: This was an analytical cross‑sectional study where informationand opinions of experts and then designing tools and assessing the face validity in the first phaseand content validity, construct validity, test–retest reliability, and internal consistency of questionsin the second phase were examined. The initial themes and structures were determined based onthe literature Review and the opinion of experts. Three hundred students of Yazd Universities wereselected by cluster sampling and included in the study. All analyses were performed in SPSS andAMOS software version 24 with a significance level of less than 5%.RESULTS: The final version of the scale had 39 questions in eight dimensions. The overall Cronbach’salpha value was 0.89, and for each dimension, it was more than 0.7. The content validity ratio andcontent validity index for the whole tool were 0.87 and 0.94, respectively. The results of confirmatoryfactor analysis showed that the latent construct model had good fit (X2/df = 4.31; RMSEA = 0.07;CFI = 0.94; NFI = 0.92; TLI = 0.91, P < 0.001).CONCLUSION: In this study, a valid and reliable tool based on PMT to predict smoking behaviorin students was introduced. This tool can be used in interventional and etiological studies. It alsohas questions related to the coronavirus disease 2019 (Covid 19) virus and can be used in thecoronavirus pandemic.
