--- - |2 Abstract 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. - Journal of Clinical Psychology, EarlyView.
