Insight and psychopathology in never-treated schizophrenia.
Insight is a feature of schizophrenia related to psychopathology, which could be modified by treatment. The real relationship will be more evident in the never-treated state. This study compared insight and its relationship to psychopathology in 143 never-treated patients with chronic schizophrenia with 183 treated patients. The treated patients had not received any structured intervention for improvement of insight. The item on insight and judgment from the Positive and Negative Syndrome Scale for schizophrenia was used as a measure of insight. Never-treated patients were more ill and poorer in insight than the TT group. Sex, age, duration of illness, negative symptoms related to insight only in the TT group. Positive symptoms score correlated with insight in both the groups, but negative symptoms correlated with insight only among the treated patients. Delusions, uncooperativeness, and poor attention predicted 27% of variation in the level of insight in the never-treated, whereas age; duration of illness; and symptoms of emotional withdrawal, difficulty in abstract thinking, and uncooperativeness predicted 30.3% of variation in insight of the TT group. The observed differences between the never-treated and treated subjects were due to influence of treatment on the association between insight and psychopathology. A subgroup of patients with a treatment-resistant trait of negative symptoms associated with poor insight was hypothesized.
