Insight in schizophrenia and mania

Abstract

We administered a series of 12 brief vignettes depicting examples of positive, negative, and manic psychopathology in everyday language to 21 patients with schizophrenia and 20 patients with mania. We asked patients to rate, first, how similar they were to the individual depicted in each vignette, and, second, the degree to which the experiences or behaviors depicted in each vignette reflected mental illness. Psychiatrists also rated how similar each patient was to each vignette. At admission, patients with schizophrenia rated themselves as significantly less similar to the positive symptom vignettes than the psychiatrists rated them. Patients with mania did not differ from the psychiatrist in rating their similarity to the vignettes, but they strongly denied that the vignettes reflected mental illness.
