The reliability of the Thematic Apperception Test

Controversy over the TAT's reliability may stem largely from the mis-application of traditional psychometric measures, which are inappropriate to this test. The TAT is implicitly based on a multiple regression model, for which coefficient alpha is not appropriate. Also, test-retest correlations may be adversely affected by the standard instructions to write a "creative" story. In a test-retest study, 47 high school students retook the TAT after a year with instructions designed to break the implicit set to produce a new and different story from that previously written. The test-retest correlations were r = .48 (need for affiliation) and .56 (need for intimacy), or approximately the same as those for, e.g., the MMPI, 16PF, and CPI, It was demonstrated that this high stability over time was not due to subjects' recalling and repeating previous responses. Finally, it was shown that alpha considerably underestimated the test-retest reliability, contrary to assumptions of classical psychometrics.     

Gender bias on the Thematic Apperception Test

Thirty male and 30 female college students generated stories to a set of nine Thematic Apperception Test (TAT) cards with either male or female stimulus characters. The Fine scoring system was factor analyzed to produce seven factor clusters plus three outcome variables. Multiple analysis of variance (MANOVA) revealed a main effect for type of card. The female TAT cards elicited significantly more responses on the General Concerns scale than did the male TAT cards. A main effect for subject gender showed the females gave more responses than males on the Interpersonal Relations scale. No differences were found on the outcome variables.

Instructional Set and Thematic Apperception Test Validity

The strong controversy over the Thematic Apperception Test's (TAT) validity may be partly due to the divergent results critics and advocates have obtained in their own research. It is noted that conditions of test administration are closely associated with quality of TAT research results. To demonstrate a cause of TAT invalidity, 199 adolescents were given the TAT following one of four instructional sets: neutral, following a personality test, emphasizing that the TAT is a personality test, and in a nonthreatening but structured setting. As expected, stories written after neutral instructions were valid predictors of need for achievement, affiliation, and power criteria; whereas other stories yielded nonsignificant and sometimes negative validities. It was concluded that the instructions are crucial to the quality of TAT results, and suggestions were offered to help ensure validity.     

Origin and history of the Thematic Apperception Test images

The origin and history of each of the images appearing on the 1943/1971 edition of the Thematic Apperception Test is presented. This information corrects and supplements that provided by Murray (1943/1971) in the test manual. Authorship of the test, including the contributions of Christiana Morgan, is discussed. The material presented expands the historical record and may serve as an aid in test interpretation.     

Origin and history of the earliest Thematic Apperception Test pictures

I present the origin and history of the "Series A" pictures of the Thematic Apperception Test (TAT; Murray, 1943/1971). The TAT and its pictures evolved during the 1930s and early 1940s. The Series A pictures were probably never a distinct, fixed set of cards as the name seems to imply. The pictures used were in a constant state of flux with additions, deletions, and modifications common. In this article I describe the origins of the test and catalog its earliest pictures. It is hoped that familiarity with the test's development will increase appreciation for the efforts of the test's originators and add perspective and depth to one's awareness of the stimuli used.     

Differential validity of the Defense Mechanism Manual for the TAT between Asian Americans and Whites. Thematic Apperception Test

Thematic Apperception Test (Murray, 1943) responses of 69 Asian American (hereafter, Asian) and 83 White students were coded for defenses according to the Defense Mechanism Manual (Cramer, 1991b) and studied for differential validity in predicting paper-and-pencil measures of relevant constructs. Three tests for differential validity were used: (a) differences between validity coefficients, (b) interactions between predictor and ethnicity in criterion prediction, and (c) differences between groups in mean prediction errors using a common regression equation. Modest differential validity was found. It was surprising that the DMM scales were slightly stronger predictors of their criteria among Asians than among Whites and when a common predictor was used, desirable criteria were overpredicted for Asians, whereas undesirable ones were overpredicted for Whites. The results were not affected by acculturation level or English vocabulary among the Asians.     

Interpersonal affect in Thematic Apperception Test responses: a scoring system

Affect toward "parental," "spousal," and "nonspousal" figures in TAT responses was evaluated. Positive and negative scores ranging from +2 to -2 were assigned to each story. Norms were based on frequent responses stimulus-pull and quality Of responses Test-retest rendered .88 similarity in affect and 86% in orientational others categories. Interscorer's agreements on affective scores ranged from .93 to .97 and interpersonal categories ranged from 96% to 98%. Higher positive "spousal" than "parental" and "nonspousal" affect was hypothesized to associate with marital adjustment. Thirty married Caucasian middle-class couples were individually interviewed. Cards 1, 2, 4, 6 GF, 10 13 FM and 16 as well as the Dyadic. Adjustment Scale were administered. Results, significant at .001 level, were discussed in terms of development in interpersonal choices.     

Formal characteristics of Thematic Apperception Test stories as indices of emotional disturbance in children

Formal characteristics of stories told about picture cards from the Thematic Apperception Test (TAT) were defined as reflecting the storyteller's ability to accomplish the task and were distinguished from content that expresses the unique concerns of the individual. It was argued that increased emphasis on formal aspects of TAT responses is warranted, because these characteristics can be determined more objectively and are more suitable for direct group comparison. Therefore, the variables included in our study consisted of an integration and expansion of formal characteristics previously developed with adults, which showed promise in differentiating disturbed and normal groups of children. Based on these formal characteristics of TAT stories, 95% of the comparison group members and 85% of the disturbed group members were correctly classified. Emotionally disturbed boys (n = 40) differed from a comparison group (n = 40) on seven formal scoring categories which were hypothesized to differentiate the groups.
