Abstract

The aim of this study was to test the psychometric properties of Adlerian Inferiority and Superiority Complex Shortened Scales in a Turkish sample. Exploratory factor analysis sample consisted of 331 individuals (192 female and 139 men) between the ages of 15 and 65, while confirmatory factor analysis sample consisted of 192 individuals (113 female and 79 men) between the ages of 15 and 64. As a result of exploratory factor analysis, inferiority complex showed a structure of 10 items, while superiority complex showed a structure of 9 items. Confirmatory factor analysis showed that the scales had acceptable fit values in a two-factor structure. Findings related to the internal consistency coefficient, test-retest reliability and concurrent validity showed that Adlerian Inferiority Complex and Superiority Complex Shortened Scales are valid and reliable tools for evaluate the inferiority and superiority complex levels of individuals aged 15 and older in Turkey sample.
