Psychometric Evaluation of the Short Form of Situational Temptation Scale for Smoking Cessation among Iranian Workers Based on Transtheoretical Model

Abstract

Background: Situational temptations are important key points for smoking cessation. However, temptation to engage in smoking across different situations is yet challenging. In Iran, there is no measurement to assess situational temptations among workers. Objectives: The current study aimed at psychometrically evaluating the short form of situational temptations scale for smoking cessation based on transtheoretical model. Methods: By stratified random sampling method, 218 male current smoking automobile factory workers were selected and assessed through the short form of situational temptation scale. Exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and Cronbach’s alpha were applied. Results: The mean age of the workers was 30.52 ± 6.66 years. CVI and CVR of each question were > 0.71. The result of EFA with principal component approach showed 1 factor with 45% cumulative variance and KMO was 91%, which were the good fit index in CFA. In the area of CFA, the result showed REMSEA = 0.006, GFI = 0.973, AGFI = 0.955; P value = 0.452, which were the good fit index in CFA. The reliability was also confirmed with Cronbach’s alpha (α = 80.1%). Conclusions: The current study approved the short form of situational temptation scale for smoke cessation. However, to ensure a reliable/valid instrument to realize smoking behaviors, doing more researches are recommended.
