Adaptation of the Colonoscopy Satisfaction and Safety Questionnaire to Turkish Language and Determination of Its Psychometric Properties

Abstract

Aim: This study was conducted to adapt the Colonoscopy Satisfaction and Safety Questionnaire into Turkish and evaluate its psychometric properties.

Method: The study was conducted with a methodological design recruiting a sample of 181 individuals scheduled for colonoscopy procedures.

Results: Content validity index for a single dimension yielded a satisfactory score of 0.95. The study also revealed strong and consistent time-dependent invariance correlation coefficients ranging from 0.82 to 0.97, indicating reliability over time. A robust and positive relationship was detected between the item scores recorded during the pretest and posttest assessments. After item analysis, three items were removed from the questionnaire, resulting in a 13-item scale that displayed good internal consistency with a Cronbach's alpha coefficient of 0.86.

Conclusion: The findings suggest that the Turkish version of the Colonoscopy Satisfaction and Safety Questionnaire is well-suited for use in research related to patients undergoing colonoscopy procedures. As a result of this study, it was determined that it is an appropriate tool for assessing the satisfaction of patients undergoing colonoscopy.
