Objective This study extends upon the investigation of the influence of response format on the convergence between performance‐based and self‐report assessments of similar mental health constructs, to further examine the role of method variance in poor heteromethod convergence. Methods An online sample of 455 participants (57% male; mean age = 35.5 years) completed a multiple‐choice adaptation of the Thematic Apperception Test (TAT)—the Iowa Picture Interpretation Test (IPIT)—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. Results Several significant and meaningful interrelationships emerged between the IPIT and the PAI and IPIP five‐factor scales. Conclusions Findings suggest that TAT methodology can correlate meaningfully with similar constructs assessed using self‐report when comparable response formats are utilized, offering further support for the role of method variance in precluding heteromethod relationships.
