To address the utility of the Rorschach, the author synthesized a large sample (N = 138) of empirical, quantitative research published in the past 20 years. Longitudinal and behavioral criteria and ecological incremental validity beyond self-report and interview were emphasized because of their relationship with test applications. Methodological issues (temporal consistency, diversity, clinician judgment), applications (treatment outcome, schizophrenia, thought disorder, depression and suicide risk), and selected Rorschach variables are addressed. The evidence reveals that many Rorschach variables are efficient tools for clinical, forensic, and educational applications. The test is particularly useful in (a) individualizing case conceptualizations and interventions and (b) predicting and evaluating outcomes. These conclusions are consistent with using the Rorschach as a behavioral problem-solving test that illuminates the interaction among psychological, biological, and environmental factors.I thank my good friends and colleagues,
