Confirmatory Factor Analysis of Safe Driving Self-Efficacy among Tabriz Citizens

Background: The advent of industrialization and the invention of the automobile have increased traffic accidents, impacting the quality of life. The purpose of this study is to evaluate the validity of the safe driving self-efficacy tool using confirmatory factor analysis (CFA) to confirm the factors extracted from the exploratory factor analysis stage and also to evaluate the reliability of this tool. Methods: This study involved ۶۰۰ individuals residing in Tabriz, aged ۲۰-۵۰ years. The questionnaire utilized in this study was a researcher-made tool and evaluated for structural validity, goodness-of-fit, and internal consistency. Construct validity was tested using the first and second-order CFA using AMOS۲۳ software. The internal reliability of the questionnaire was determined based on Cronbach’s alpha coefficient (α > ۰.۷). Results: The study analyzed ۵۸۹ questionnaires from ۶۰۰ participants, with a mean age of ۳۵.۰۴ years (SD = ۸.۳۶۷). The majority of respondents had a driving experience and a history of traffic accidents, primarily within urban areas. The CFA also confirmed five factors with ۴۲ questions, which showed positive results. The value of Cronbach’s alpha coefficient for all factors was more than ۰.۷. Conclusion: Out of the ۶۰ items in the questionnaire, ۴۲ items were confirmed with appropriate goodness-of-fit indicators. The amalgamation of these constructs within the model effectively measures the concept of safe driving self-efficacy, thereby establishing the tool's reliability. As a result, this survey can serve as a valuable benchmark for evaluating individuals' self-efficacy concerning safe driving practices.
