Abstract
This study was conducted for the purpose of adapting the Decisional Balance Scale (DBS) for Turkish and testing its validity and reliability to be able to measure adults’ perceptions of the benefits and negative consequences of cigarette smoking. The tool was administered to a sample of 486 participants chosen using a random sampling method, and the test-retest analysis was conducted with 365 individuals from the original sample. After the scale was reviewed several times by experts in English and Turkish, data were analysed by factor analysis, Student t-test, Kendall W and dependent t-test. The DBS pros subscale's Cronbach alpha value was found to be 0.85 and the cons subscale was 0.81. The item to total score correlation coefficient was 0.37–0.77 for the pros subscale and 0.50–0.71 for the cons subscale. The scale's factor load was 0.39–0.79. In the confirmatory factor analysis results it was determined that the scale was appropriate and that the scale had a two-factor construct (GFI 0.90 and CFI 0.93). The opposite group approach supported the scale's construct validity. The results supported DBS's validity and reliability. The Turkish version of the DBS was found to be a reliable and valid tool and appropriate for use.
