Abstract

This study examined whether computerized text analysis of Thematic Apperception Test (TAT) protocols could differentiate patients operating at neurotic, borderline, and psychotic levels of personality organization (LPO). From a large University psychological clinic archival database, I identified fifty-­‐two (N = 52) patients whose files: a) contained verbatim TAT responses; and b) included diagnosis indicative of neurotic, borderline, or psychotic LPO. Verbatim TAT transcriptions were input and analyzed using Linguistic Inquiry Word Count (LIWC) software. I hypothesized that 1) The use of cognitive words would be more common among the TAT protocols of the neurotic patients than among the protocols of the borderline and psychotic patients; 2) the use of negative emotion words and negation words would be more prominent among the psychotic and borderline patient protocols than among the neurotic patients. A limited number of psychotic protocols meeting selection criteria required me to eliminate the psychosis category in the analysis; however, the results of one-­‐way ANOVA found that the neurotic group used cognitive words during TAT administration at a significantly higher rate than did the borderline group. The effect size for this difference was moderate to large.
