A Systematic Narrative Review of Evaluating Change in Psychotherapy with the Rorschach Test

In 2004, Gronnerod conducted a meta-analysis on the use of the Rorschach Test to detect change in psychotherapy. Results showed which Rorschach variables were associated with change in clients, and to what extent. The purpose of this study was to update the picture from the year of publication of the previous meta-analysis until 2019. A systematic review of the literature was carried out, including 17 studies of relevance to this research. Results showed that the Rorschach Test captures the changes in patients after psychotherapy, particularly when treatment is tailored to the unique needs of clients. We describe the limitations of the studies included in this systematic review and propose strategies to increase the effectiveness of using the Rorschach to evaluate treatment outcome.
