Validity and Reliability of Four Instruments for E-Cigarette Dependence and Sensory Factors in E-Cigarette Use and Correlations Between These Measurements

Abstract

The study aimed to examine the psychometric properties of Turkish versions of e-FTCD, PS-ECDI, EDS, and SEES. 1050 individuals aged 18+ included to assess validity, reliability, and interrelation among these scales. Scale psychometrics explored using statistical methods, including construct validity, confirmatory factor analysis, and reliability stats. The factor loadings for e-FTCD ranged from 0.528 to 0.939, PS-ECDI from 0.404 to 0.899, EDS from 0.779 to 0.897, and SEES from 0.733 to 0.849. The Cronbach’s alpha coefficients for e-FTCD, PS-ECDI, EDS (4-Item), EDS (8-Item), EDS (22-Item), and SEES were 0.561, 0.805, 0.905, 0.949, 0.984, and 0.934, respectively. The correlations were moderate between SEES and both e-FTCD (0.317) and PS-ECDI (0.394), e-FTCD was strongly correlated with PS-ECDI (0.750) and moderately with EDS versions (0.577–0.586). Correlations between the PS-ECDI and EDS versions ranged from 0.698–0.713. All four tools valid, reliable for 18+ in Türkiye. Also, positive correlation between sensory e-cigarette expectation and dependence.
