Inter-rater reliability and factor analysis of the Brazilian version of the Schedule for the Assessment of Insight: Expanded Version (SAI-E).
OBJECTIVE
The Schedule for the Assessment of Insight - Expanded Version consists of 11 items that encompass: awareness of having a mental illness, ability to rename psychotic phenomena as abnormal, and compliance with treatment. The objective of the study was to evaluate the inter-rater reliability and to study the factorial structure of the Brazilian version of the instrument.


METHODS
The Brazilian version of the Schedule for the Assessment of Insight - Expanded Version was used for the assessment of insight of 109 psychotic inpatients, 60 of whom had the interview tape-recorded in order to be scored by an independent evaluator. Intraclass correlation coefficient (ICC) was adopted as the inter-rater reliability coefficient. In the factor analysis, principal components analysis and Varimax rotation were adopted.


RESULTS
Inter-rater reliability coefficients from good to excellent were found for the individual items of the Schedule for the Assessment of Insight - Expanded Version with ICC values ranging from 0.54 to 0.82. Regarding the total score, inter-rater reliability was excellent, with ICC = 0.90. A factorial structure similar to the one obtained by the original version of the Schedule for the Assessment of Insight - Expanded Version was found, with 3 factors accounting for 71.72% of variance.


CONCLUSIONS
In the Brazilian context, the Schedule for the Assessment of Insight - Expanded Version presented good inter-rater reliability and factorial structure compatible to the insight dimensions that are intended to be evaluated.
