The present research aims at investigated psychometric properties of the Adolescent Self Regulatory Inventory (ASRI) among a sample of Iranian female students. The ASRI is a theoretically-based questionnaire that taps two temporal aspect of self-regulation (regulation in the short and long term). The subjects consisted of all female students of secondary school who studies in schools of Shahin-Shahr (city in
Isfahan Province) during the school year 2014-2015. In this regard, 336 students of Shahin-Shahr secondary schools were selected using random cluster sampling method and were asked to completed self-report questionnaire focused on intentional self-regulation (Adolescent Self-Regulatory Inventory and Model of Selection, Optimization, and Compensation (SOC) ) and psychological adjustment (Adjustment Inventory for High School Students). Confirmatory factor analysis demonstrated that internal consistency of the long-term and short-term factors was satisfactory. Requirements for concurrent and construct validity were met. Cronbach's alpha coefficient for short-term and long-term self-regularly subscales were 0/81 (ST) and 0/80 (LT). Finally, the results suggested that ASRI was two-factor, reliable tool for assessing and evaluating dimensions of intentional self-regulation in adolescence.

This study aimed to determine the psychometric properties of the Smartphone Addiction Scale (SAS) in a sample of 208 Iranians. The convenience sampling method was employed to select individuals with smartphones living in Tehran. The participants completed the SAS and Young’s Internet Addiction Test (IAT). Construct validity and convergence validity were employed to analyze the scale validity, whereas the retest method and Cronbach’s alpha were adopted to evaluate its reliability. According to the confirmatory factor analysis results of evaluating the construct validity and the SAS structure, the research data are consistent with the model. In other words, the fitting indices were within an appropriate range, and the SAS had a factor structure with six subscales. Therefore, the construct validity of the SAS was confirmed. Moreover, its convergence validity was confirmed with Young’s IAT (r= 0.75). The retest correlation coefficient (r= 0.93) and Cronbach’s alpha for internal consistency (α= 0.92) confirmed the reliability of the scale. Therefore, the 33-item SAS had acceptable psychometric properties in six scales. It can be used as a valid and reliable tool to analyze an Iranian population.
