Abstract
BACKGROUND: Prevention of smoking is very important at a young age and during the student
period. 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 motivation
theory (PMT).
MATERIALS AND METHODS: This was an analytical cross‑sectional study where information
and opinions of experts and then designing tools and assessing the face validity in the first phase
and content validity, construct validity, test–retest reliability, and internal consistency of questions
in the second phase were examined. The initial themes and structures were determined based on
the literature Review and the opinion of experts. Three hundred students of Yazd Universities were
selected by cluster sampling and included in the study. All analyses were performed in SPSS and
AMOS 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’s
alpha value was 0.89, and for each dimension, it was more than 0.7. The content validity ratio and
content validity index for the whole tool were 0.87 and 0.94, respectively. The results of confirmatory
factor 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 behavior
in students was introduced. This tool can be used in interventional and etiological studies. It also
has questions related to the coronavirus disease 2019 (Covid 19) virus and can be used in the
coronavirus pandemic.
