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

Abstract

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.

The Processometric Consensus Rorschach Test (pCRT-II) – An Improved Evaluation System

“…The low intercorrelations between the pCRT-II subscales and the other measures may be partly traced back to the different nature of the assessment procedures. Specifically, several studies compared the results obtained with self-report and performance-based tests and found essential differences between them (Hartmann & Opaas, 2023; McCredie & Morey, 2019; Morey & McCredie, 2019). It is plausible to assume that the different methods assess the complex organization of a system (i.e., personality or relationship) at a unique level (Meyer, 1997).…”

Identification of Individual Intolerance Behaviour Trends Through Thematic Apperception Test (TAT) Analysis

“…Thematic Apperception Test is a test tool developed by Christina Morgan and Henry Murray, the theoretical basis of this test is that a human will give a view of his position in an ambiguous problem [12][13] [14]. Subconsciously the subject of the TAT will write a "character" analogy of a picture of the problem from his point of view.…”
