ABSTRACT
OBJECTIVES:
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.METHOD:
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 percent of variance.CONCLUSION:
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.RESUMO
OBJETIVOS:
O Schedule for the Assessment of Insight - Expanded Version é constituído por 11 itens que abordam reconhecimento de se ter um transtorno mental, capacidade de renomear fenômenos psicóticos como anormais e adesão ao tratamento. O objetivo do estudo foi avaliar a confiabilidade entre avaliadores e estudar a estrutura fatorial da versão brasileira do Schedule for the Assessment of Insight - Expanded Version.MÉTODO:
A versão brasileira do Schedule for the Assessment of Insight - Expanded Version foi utilizada na avaliação de 109 pacientes psicóticos internados, dos quais 60 tiveram a entrevista gravada para atribuição de escores por avaliador independente. O coeficiente de correlação intraclasse (ICC) foi utilizado na avaliação da confiabilidade entre avaliadores. Para a análise fatorial foram adotadas análise de componentes principais e rotação varimax.RESULTADOS:
A confiabilidade entre avaliadores para os itens do Schedule for the Assessment of Insight - Expanded Version encontrada esteve entre boa e excelente, com ICC variando de 0,54 a 0,82; para o escore total foi excelente, com ICC = 0,90. Uma estrutura fatorial semelhante à obtida para a versão original do Schedule for the Assessment of Insight - Expanded Version foi encontrada, com três fatores explicando 71,72 por cento da variação.CONCLUSÃO:
No contexto brasileiro, o Schedule for the Assessment of Insight - Expanded Version apresentou boa confiabilidade entre avaliadores e estrutura fatorial compatível com as dimensões do insight que pretende avaliar.
