Reliability, Validity, and Factorial Analysis of a Short Version of the Self-Regulation Inventory

The study examined psychometric properties of a short version of the Self-Regulation Inventory (SRI-S) including reliability, validity, and exploratory factor analysis of the SRI-S in an Iranian students. Six hundred and seventy six Iranian volunteers (294 \males, 382 females) from universities in Iran 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). The results of explarotary factor analysis supported a single general factor of self-regulation and a five factor structure including Positive Actions, Controllability, Expression of Feelings and Needs, Assertiveness, and Well-Being Seeking. The convergent and discriminant validity of the SRI-S were supported by an expected pattern of correlations between the scale and the measures of personality and mental health. All correlation coefficients between the mean scores on the SRI-S and scores of the extraversion, neuroticism, psychological well-being, and psychological distress were statistically significant.
