Confirmatory Factor Analysis and Reliability of the Adolescents Self-Regulation Inventory

the present study aimed to assess psychometric propertiesof the Adolescent Self-Regulatory Inventory (ASRI; Dias, Garcia del Castillo & Moilanen, 2014) among a sample of Iranian adolescents. The study was descriptive. Thirty hundred and fifty five students were selected from Karaj schools of Alborz province by multistage sampling method. The participants completed the ASRI and theIranian Adolescents Risk-taking Scale (IARS; Zademohamadi, Ahmadabadi & Haidari, 2011).The results of confirmatory factor analysis supported the two-factor model of the ASRI.The correlation between the ASRI and the IARS was between 0.30 and 0.51, which indicated the concurrent validity of the ASRI. The high correlations between the total score of the scale and scores of the subscales indicated construct validity of the ASRI. The reliability of the ASRI was satisfactory: The Cronbach's alpha coefficient and test-retest coefficient of the short term subscale were 0.81 and 0.75, respectively, the Cronbach's alpha coefficient and test-retest coefficient of the long term subscale were 0.77 and 0.71, respectively, and the Cronbach's alpha coefficient and test-retest coefficient of the ASRI were 0.87 and 0.74, respectively. The findings suggested that the ASRI had appropriate psychometric properties and can be used for research purposes in Iran.
