Abstract
Objective: The present study aimed to investigate the validity and reliability of the Persian version of brief self-control scale (BSCS) in Iranian motorcyclists.
Methods: The original English questionnaire of BSCS has been translated into Persian using the direct-reverse approach. A total of 130 motorcyclists aged 18–65 years old in Iran–Kashan completed the questionnaire. Validity was determined by content validity methods, structural validity through factor analysis, and also the convergence and divergence validity using Spearman correlation coefficient. The intra class correlation coefficient (ICC) was calculated to estimate the reliability of the self-control tool. Reliability was calculated using Cronbach's alpha.
Results: The mean and standard deviation of the age at the time of study was 38.5 ± 13.5 years old and all of the subjects were male. Cronbach's alpha coefficient of the whole questionnaire (BSCS) was 0.81, which was good in this regard. The ICC coefficient was 0.88 with confidence interval of (0.8–0.93), which confirmed the repeatability of this tool. Exploratory factor analysis (EFA) yielded a two-factor solution accounted for 42% of the observed variance.
Conclusion: This study showed that Persian version of BSCS has a good reliability and validity for self-control in the Persian language community.
The Brief Self-Control Scale (BSCS) has good internal consistency.
The Brief Self-Control Scale (BSCS) has acceptable reliability.
Brief Self-control Scale (BSCS) has acceptable validity and reliability in the population studies.
