Abstract
Personality priorities are important concepts in Adlerian theory, contributing to understanding and conceptualizing clients’ lifestyles. Even though Adlerian psychology promises multicultural applications and has been interested in Turkey, no instrument measuring personality priorities has been developed or adapted into Turkish. Therefore, the purpose of this study was to adapt the Adlerian Personality Priority Assessment (APPA) into Turkish and examine its psychometric properties with a sample of Turkish undergraduate students. This study was conducted in three steps. In the first step, a linguistic equivalence test was performed with a sample of 73 students enrolled at the Department of English Language Education. In the second step, the structure of the APPA was examined using exploratory and confirmatory factor analyses with a sample of 1,279 undergraduate students. In the final step, test-retest reliability was tested with a sample of 93 undergraduate students within 4-week interval. The results of the linguistic equivalency study revealed that translations were linguistically and culturally proper. According to the exploratory and confirmatory factor analyses, the Turkish form of the APPA consisted of 24 items loaded with four factors consistent with the original form. The results also revealed good levels of internal and test-retest reliabilities. The findings of this study showed that the Turkish form of the APPA is a valid and reliable instrument, and it can be used in research and practice with Turkish populations. The results and limitations were discussed, along with implications for future research and practice.
