Inter-rater reliability and factor analysis of the Brazilian version of the Schedule for the Assessment of Insight: Expanded Version (SAI-E)

Abstract

A b s t r a c t 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 InsightExpanded Version was found, with 3 factors accounting for 71.72% 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.

Insight and emotion regulation in schizophrenia: A brain activation and functional connectivity study

“…Three subscale scores can be calculated, as well as a subtotal score (items 1–9), with higher scores indicating better clinical insight. These subscales have been confirmed with factor analysis in several studies that found three similar factors ( Dantas and Banzato, 2007 ; David et al, 2003 ; Konstantakopoulos et al, 2013 ). Subscale scores as well as SAI-E subtotal score were used for fMRI analyses.…”

Instruments to measure sexual dysfunction in community and psychiatric populations

“…The scale has also been used in diabetic and epileptic groups, demonstrating an ability to discriminate between clinical populations [47,48]. The SAI-E also demonstrated high internal consistency reliability for arousability (α=0.90) and anxiety (α=0.90) [49].…”

Métodos De Avaliação Da Adesão Farmacoterapêutica Adotados No Brasil

“…Outro resultado observado foi que independentemente do método utilizado muitos autores (25,28,38,40,44,52,55,59,60,63) não deixam claro qual a definição de parâmetro de adesão utilizado em pelo menos um dos métodos adotados, sendo possível apenas observar quais os métodos utilizados. Quanto à verificação da definição de parâmetros de adesão por dose esquecida foi observada valores distintos para um mesmo tratamento, como é o caso da Aids cujos parâmetros vaiaram de >80 a >95% (8,(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)26,27).…”

“…Entre os métodos, verificou-se que foram utilizados quase que exclusivamente os indiretos, sendo os instrumentos de medida de adesão como questionários (13,14,25,27,(35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50)(51)(52)62) os mais frequentes. Quando se opta pelo uso de instrumentos de medida de adesão, tem sido a escolha para boa parte dos pesquisadores o teste de Morisky (79), da língua inglesa Morisky Medication Adherence Scale-4 items (MMAS-4) (80), originalmente desenvolvido para avaliar a adesão ao tratamento de hipertensão arterial sistêmica, pela avaliação de atitudes relacionadas ao tratamento.…”
