Convergence between Thematic Apperception Test (TAT) and self-report: Another look at some old questions.
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.
