Examining the Psychometric Properties of an English Translation of the Shortened Inferiority and Superiority Complex Scales

Abstract: The present study set out to assess the psychometric properties of the English translation of the short Inferiority Complex (COMPIN-10) and Superiority Complex (SUCOMP-10) scales, which are based on Adlerian Individual Psychology and originally developed in Serbian, on a Canadian sample. Students ( N = 565) completed the shortened inferiority and superiority complex scales and the depression facet scale from a Big Five personality inventory. Both scales showed approximated normal distributions and had good reliability. The results of the confirmatory factor analysis confirmed the unidimensional structure for both scales. Results also showed that the depression scale scores were positively correlated with the inferiority complex scores and negatively with the superiority complex scores. Findings support using the shortened inferiority and superiority complex scales in English.
