psychometri properties of a short version of the self-regulation inventory in a sample of iranian population

the main purpose of this study was to examine psychometric properties of a short version of the self-regulation inventory (sri-s) including internal consistency, test-retest reliability, content validity, and convergent and discriminant validity. three hundred and fifty seven iranian volunteers (150 males, 207 females) were included in this study. all participants were asked to complete the sri-s (marques, ibanez, ruiperez, moya, & ortet, 2005), the eysenck personality questionnaire-revised short scale (epq-rs; eysenck, eysenck, & barrett, 1985), and the mental health inventory (mhi-28; besharat, 2009). test-retest reliability and internal consistency of the sri-s were examined at satisfactory levels. content validity of the sri-s was calculated according to kendall's coefficients of concordance for sri-s subscales including positive actions, controllability, expression of feelings and needs, assertiveness, well-being seeking, and sri-s total score. all kendall's coefficients of concordance were statistically significant. self-regulation scales revealed significant positive associations with extraversion and psychological well-being, as well as significant negative associations with neuroticism and psychological distress. these results confirmed the convergent and discriminant validity of the sri-s. it was concluded that the sri-s can be considered as a reliable and valid scale to measure self-regulation in iranian samples.
