Exploring the Test–Retest Reliability of the Adlerian Personality Priority Assessment

The authors assessed the test–retest reliability of the Adlerian Personality Priority Assessment (APPA) with a convenience sample of university students (N = 120). Participants completed the APPA twice within a 3-week interval. Intraclass correlation (two-way mixed model) was used to measure test–retest reliability. The APPA demonstrated good temporal reliability for all four factors, as well as initial evidence of convergent validity. The results provide further evidence for counselors' use of the APPA to identify individuals' personality priorities.
