Background:
Young people's expectations regarding the consequences of vaping are critical determinants of their vaping behavior; therefore, valid and reliable instruments are essential for accurately assessing these expectations. The aim of this study was to adapt the "Short Form Vaping Consequences Questionnaire" to Turkish culture and to evaluate its psychometric properties.
Methods:
This methodological study included 840 university students. Data were collected face-to-face via Google Forms and analyzed using SPSS 22.0 and AMOS 25. The internal structure of the scale was examined. To evaluate the cultural and psychometric adaptation of the scale, validity was assessed through content and construct analyses (exploratory and confirmatory factor analyses), while reliability was evaluated using item-total correlations, Cronbach's alpha, and test-retest.
Results:
For the Turkish version, item-level content validity index values ranged from 0.83 to 1.00, scale-level content validity index was 1.00, and average scale-level content validity index was 0.95. Confirmatory factor analysis confirmed the original four-factor structure, with standardized loadings between 0.786 and 0.967. Cronbach's alpha values ranged from 0.921 to 0.982. Test-retest results showed no significant differences (p > 0.05), and intraclass correlation coefficients values ranged from 0.801 to 0.979 (p < 0.001).
Conclusions:
The findings of this study provide evidence of validity and reliability for the Turkish version of the Short Form Vaping Consequences Questionnaire in assessing vaping outcome expectancies among both users and non-users in university students.
