Objective:
This study presents an examination of the influence of response format on convergence between performance-based and self-report assessments of similar mental health constructs, to determine if such method variance might account for prior findings of lack of relationship.
Methods:
An online sample of 455 participants (57% male; average age, 35.5) completed a multiple-choice version of the Rorschach and two self-report instruments, the Personality Assessment Inventory (PAI) and the International Personality Item Pool (IPIP) representation of the domain traits of the five-factor model (FFM).
Results:
Several significant interrelationships emerged between the Rorschach Amplified Multiple Choice Test and the PAI and IPIP five-factor scales.
Conclusions:
These findings suggest that the Rorschach can correlate meaningfully with similar constructs assessed using self-report methodology when comparable response formats are utilized.
