Objective: In recent years, studies about identity development have focused on processes in identity development. The aim of this study was to adapt into Turkish the Dimensions of Identity Development Scale which measures processes in identity development into Turkish.
Method: The Dimensions of Identity Development Scale was administered to 602 participants (322 females, 280 males) in total, aged between 18-23. To determine factor structure of the scale, exploratory and confirmatory factor analysis, and for reliability, internal consistency analysis were performed. Correlations between identity development dimensions and score of the Satisfaction with Life Scale were evaluated for criterion validity testing. To determine identity status cluster analysis was performed.
Results: Results of exploratory (explained variance 57.43%) and confirmatory factor analysis showed that the Dimensions of Identity Development Scale was valid. Correlations between the identity development dimensions and score of the Satisfaction with Life Scale were statistically significant. Internal consistency coefficients (commitment making 0.88, identification with commitment 0.87, exploration in breadth 0.84, exploration in depth 0.78, ruminative exploration 0.79) showed that the Dimensions of Identity Development Scale was reliable. In the cluster analysis, six identity status (achievement, foreclosure, moratorium, diffused diffusion, carefree diffusion, undifferentiated) were found.
Conclusion: The Dimensions of Identity Development Scale is a valid and reliable instrument for the assessment of adolescents identity development.
Key words: Validity, reliability, identity development, dimensions of identity development scale
