Abstract
This study presents results of a 1-year follow-up investigation of the causal model of insight in schizophrenia using a subsample of acute patients starting or switching to amisulpride included in an earlier study. Our causal model of insight based on the Positive and Negative Syndrome Scale factors, with the positive, negative, and autistic preoccupation factors designated as the primary predictors, and the activation factor as a mediating variable of insight was examined for fitness at the stabilized stage (8 week) and at the chronic stage (1 year) using the structural equation modeling method. Results showed that the intercorrelations among the factors and regression coefficients toward insight changed in their magnitudes, but the validity of our hypothesized model of insight was still confirmed for both the stages with nearly perfect goodness-of-fitness indices. The fitness of the model was also confirmed for the longitudinal changes in the scores of insight and psychopathology. An alternative model, which included the anxiety/depressive factor as a second mediating variable between insight and the positive and negative factors, was also found to be valid for both the stages. A post-hoc causal model with anxiety/depressive factor showed tentative evidence favoring anxiety/depressive variable predicting insight than the other way around.
