Investigating reliability and validity of Persian version of the Attentional Style Questionnaire(ASQ)

In spite of increasing importance of attentional control in conceptualization of psychopathology,there are a few scales to measure it. It is necessary to use valid and reliable scale to study this construct in Iranian studies.This study aimed to provide and investigate psychometric characteristics of Persian version of the attentional style questionnaire.

The sample of 426 students were selected by available sampling and completed persian version of the attentional style questionnaire, attentional control(Derryberry &Reed,2002)and repetitive thinking(Ehring et al,2011) scales. Construct validity were evaluated through confirmatory factor analysis. Convergent and divergent validity were assessed by pearson correlation. Reliability was calculated using Cronbach s alpha method, test-retest and Composite reliability..

factor analysis indicated that two-factor model (congnitive avoidance/distractibility and focusing) provided good model fit. significant correlations between these factors and attentional control, and repetitive thinking scales confirmed convergent and divergent validity. Cronbach s alfa for both factors were 0/75 and test-retest coefficient for cognitive avoidance/distractibility and focusing were 0/88 and 0/73 respectively also composite reliability were 0/81 and 0/84 respectively.

Persian version of attentional style questionnaire characterized two factors and has been demonstrated to have acceptable validity and reliability to use in psychological researches in Iranian population
