Rorschach’s Perceptual Thinking Index as A Diagnostic Aid: Differentiating Schizophrenia and Spiritually Advanced Healthy Individuals

Objective: Schizophrenia, characterised by profound psychotic symptoms is among the most baffling mental disorders. The nuanced resemblance between these psychotic symptoms and spiritual phenomena necessitates precise differentiation to avoid significant repercussions from misdiagnosis. Existing research lacks tools sensitive to such differentiation. While the Rorschach test-based perceptual thinking index (PTI) captures aberrations in thinking and perception in psychosis, its diagnostic potential to distinguish schizophrenia from spiritually advanced healthy individuals remains unexplored. Method: This comparative study involved 20 participants per group. Schizophrenia patients, adhering to ICD-10 (DCR) criteria, were purposively sampled from the Institute of Mental Health and Hospital, Agra. Spiritually advanced healthy individuals were convenience-sampled and screened using General Health Questionnaire-12 (GHQ-12) and Spiritual Personality Inventory-Revised (SPI-R). The Rorschach Inkblot Test was administered, and the PTI scores were analysed. Results: Statistically and practically significant differences were found between the two cohorts. However, analysis of sex-specific variations within each group yielded insignificant results. Conclusion: Results indicate that PTI holds diagnostic potential for distinguishing individuals with schizophrenia from spiritually advanced healthy individuals, regardless of the sex of the respondents; putatively reducing the risk of misdiagnosing a spiritual emergency as a psychotic episode, and aiding clinicians in effective case management.
