Summary
The Revised NEO Personality Inventory (NEO-PI-R) was modified for adolescents, creating the NEO-PI-3. This updated personality assessment shows improved readability and internal consistency for younger individuals.
Area of Science:
- Psychological Assessment
- Personality Psychology
- Adolescent Development
Background:
- The Revised NEO Personality Inventory (NEO-PI-R) has shown comprehension difficulties in adolescent samples.
- Specific items were identified as problematic for this age group, impacting data validity.
Purpose of the Study:
- To revise the NEO-PI-R for improved use with adolescents.
- To develop a more accessible and reliable personality inventory for younger populations.
Main Methods:
- Identified 30 items with low adolescent understanding and 18 with low item-total correlations.
- Developed trial replacement items and selected the best ones using data from 500 adolescent and young adult respondents (ages 14-20).
- Evaluated the modified instrument (NEO-PI-3) for factor structure, internal consistency, cross-observer agreement, and readability.
Main Results:
- The revised NEO-PI-3 maintained the intended factor structure.
- The instrument demonstrated slightly improved internal consistency and cross-observer agreement.
- Readability was enhanced, with a Flesch-Kincaid grade level of 5.3.
Conclusions:
- The NEO-PI-3 is a suitable personality assessment for high school and college samples.
- The revised instrument may also be applicable to adult populations.
- This modification enhances the utility of the NEO personality assessment for younger demographics.
