Background:
- The Zuckerman-Kuhlman-Aluja Personality Questionnaire Short Form (ZKA-PQ/SF) proposes five alternative factors and 20 facets.
- Adolescent personality assessment requires instruments with strong psychometric properties.
Purpose of the Study:

Main Methods:
- Administered the A5PI-A to 1,472 adolescents aged 12-17.
- Utilized exploratory structural equation modeling (ESEM) for factor structure analysis.
- Assessed internal consistency, test-retest reliability, and convergent/divergent validity.
Main Results:
- The A5PI-A demonstrated a robust five-factor, 20-facet structure across subsamples.
- Internal consistency and 2-month test-retest reliability were satisfactory to adequate.
- High correlations between self- and parent-reports and strong convergent/divergent validity were found.
Conclusions:
