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.
