A Study of Psychometric Properties of Adolescent Self-Regulatory Inventory among Female Secondary Schools Students

Abstract

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.
