The Psychometric Properties of the Adolescent's Positive Development Inventory

The aim of the present study was to examine psychometric properties of the Positive Youth Development Inventory (PYDI; Arnold, Nott, & Meinhold, 2012). Four hundred students were randomly selected from senior high schools of Tehran city using multistage sampling method. The participants completed the PYDI. The Cronbach's Alpha coefficient and test-retest reliability were between 0.74 and 0.83. The results of confirmatory factor analysis indicated that the PYDI had an acceptable fit. All fit indices supported the model. The results indicated the construct validity and factorial structure of the PYDI as well. The composite reliability of second order latent factor had a coefficient of 0.91 which indicated a good reliability for the second order factor and whole inventory. The findings suggest that the PYDI has acceptable psychometric properties in Iranian adolescents and can be employed as a valid and reliable instrument in this population.
