Abstract :
The purpose of this study is to investigate the reliability and validity of ‘Adolescent Decision-Making Questionnaire’ that was developed by Mann, Harmoni and Power (1989) and adapted to Turkish by Çolakkadıoğlu and Güçray (2007) to be used with pre-adolescents at the ages of 13-15. The sample of the study consisted of 616 students attending high school in Adana. The research examined the construct validity of ADMQ, the correlations of the subscales with each other, criterion-related validity, Cronbach Alpha internal consistency, item-total correlations and test-retest reliability for the scale. According to the results of the confirmatory factor analysis for the construct validity measurement, the inventory showed consistency in five subscales and all items corresponded to the related subscale as in the original inventory (Friedmann and Mann, 1993) and Turkish adaptation (Çolakkadıoğlu and Güçray, 2007). Cronbach Alpha coefficient for self-esteem, vigilance, panic, cop out and complacency subscales was respectively found as .84, .85, .83, .76 and .77 and test retest reliability coefficient was found as .85, .79, .85, .67 and .78 for the same subscale order. These statistical analyses indicate ADMQ as a reliable and valid measurement to detect self-esteem and decisions making styles of pre-adolescents.
