Dimensions of hallucinations and delusions in affective and nonaffective illnesses.

The aim of the study was to examine the dimensions of hallucinations and delusions in affective (manic episode, bipolar affective disorder, and depressive episode) and nonaffective disorders (schizophrenia, acute and transient psychotic disorders, and unspecified psychosis). Sixty outpatients divided equally into two groups comprising affective and nonaffective disorders were taken up for evaluation after screening, as per inclusion and exclusion criteria. Scores of 3 or above on delusion and hallucinatory behavior subscales of positive and negative syndrome scale were sufficient to warrant rating on the psychotic symptom rating scales with which auditory hallucination and delusion were assessed on various dimensions. Insight was assessed using the Beck cognitive insight scale (BCIS). There were no significant differences between the two groups on age, sex, marital status, education, and economic status. There were significant differences in total score and emotional characteristic subscale, cognitive interpretation subscale, and physical characteristic subscale of auditory hallucination scales in between the two groups. Correlation between BCIS-total and total auditory hallucinations score was negative (Spearman Rho -0.319; P < 0.05). Hallucinating patients, more in nonaffective group, described a negative impact of hallucinating voices along with emotional consequences on their lives which lead to distress and disruption.
