Navy Computer Adaptive Personality Scales (NCAPS)

• Increase job performance
• Decrease unwanted attrition
• Enhance job/career satisfaction

NCAPS Item Delivery

• Benefits of computer-adaptive testing (CAT)
  technology
• Lower testing costs and shorter time
• More precise measurement
• Increased user acceptance
• Zinnes-Griggs Pairwise Ideal Point IRT Model
  utilized
• Item presentation
• Items presented are tailored to individual
• Paired comparison item format that is resistant
  to faking
• Probability of item endorsement higher when item
  matches individual trait level
• Trait content intermixed across items
• Increases resistance to faking

Construct-Related Validation Study NCAPS vs.
Five Factor Model

• Motivation for conducting study
• Determine relationships between NCAPS traits FFM
  representation of Personality
• Develop hypotheses a priori linking 13 traits to
  5 factors
• Identify possible gaps in NCAPS trait coverage

6
Five Personality Factors

• Openness to Experience
• Conscientiousness
• Extraversion
• Agreeableness
• Neuroticism
• Considered to be the gold standard in personality
  research

Methods

• Participants

• Personality Inventories
• NCAPS
• 100 question IPIP
• The particular IPIP items that were used for this
  study are modeled off of the previously validated
  NEO-PI-R

Limitations

• Method Variance
• IPIP is not adaptive
• NCAPS developed as Navy specific battery
• Facets
• Under-representation of trait facets due to
  adaptive nature of NCAPS
• Overall traits for IPIP instead of facets

Conclusions

• Results suggest that all of the NCAPS traits are
  somewhat encompassed by the FFM, with many being
  highly related
• Supports notion that NCAPS is a viable
  personality measure conforming to current
  psychological research
• Bodes well for the NCAPS ability to predict job
  performance
