ABSTRACT

OBJECTIVE:

The aim of this study was to translate the Structured Clinical Interview for Mood Spectrum into Brazilian Portuguese, measuring its reliability, validity, and defining scores for bipolar disorders.

METHOD:

Questionnaire was translated (into Brazilian Portuguese) and back-translated into English. Sample consisted of 47 subjects with bipolar disorder, 47 with major depressive disorder, 18 with schizophrenia and 22 controls. Inter-rater reliability was tested in 20 subjects with bipolar disorder and MDD. Internal consistency was measured using the Kuder Richardson formula. Forward stepwise discriminant analysis was performed. Scores were compared between groups; manic (M), depressive (D) and total (T) threshold scores were calculated through receiver operating characteristic (ROC) curves.

RESULTS:

Kuder Richardson coefficients were between 0.86 and 0.94. Intraclass correlation coefficient was 0.96 (CI 95 percent 0.93-0.97). Subjects with bipolar disorder had higher M and T, and similar D scores, when compared to major depressive disorder (ANOVA, p < 0.001). The sub-domains that best discriminated unipolar and bipolar subjects were manic energy and manic mood. M had the best area under the curve (0.909), and values of M equal to or greater than 30 yielded 91.5 percent sensitivity and 74.5 percent specificity.

CONCLUSION:

Structured Clinical Interview for Mood Spectrum has good reliability and validity. Cut-off of 30 best differentiates subjects with bipolar disorder vs. unipolar depression. A cutoff score of 30 or higher in the mania sub-domain is appropriate to help make a distinction between subjects with bipolar disorder and those with unipolar depression.
RESUMO

OBJETIVO:

Traduzir e validar para o português a Entrevista Clínica Estruturada para Distúrbios do Humor, mensurando sua validade, confiabilidade, bem como definindo os escores para transtornos bipolares.

MÉTODO:

A entrevista foi traduzida (para o português) e novamente traduzida para o inglês. A amostra incluiu 47 indivíduos com transtornos bipolares, 47 com transtorno depressivo maior, 18 com esquizofrenia e 22 controles. A confiabilidade entre avaliadores foi testada em 20 indivíduos com transtornos bipolares e transtorno depressivo maior. A consistência interna foi mensurada por meio da fórmula de Kuder Richardson. Análise discriminante foi realizada. Escores dos diversos grupos foram comparados; limiares para mania (M), depressão (D) e valores totais foram calculados usando curvas de "receiver operating characteristic" (ROC).

RESULTADOS:

Coeficientes de Kuder Richardson ficaram entre 0,86 e 0,94. O coeficiente de correlação intraclasse foi de 0,96 (IC 95 por cento 0,93-0,97). Participantes com transtornos bipolares apresentaram escores M e T aumentados, e escores D semelhantes aos do grupo transtorno depressivo maior (ANOVA, p < 0,001). Os subdomínios que melhor discriminaram indivíduos com doença uni ou bipolar foram energia maníaca e humor maníaco. M apresentou a melhor área sob a curva (0,909); valores de M igual ou superiores a 30 associaram-se a sensibilidade de 91,5 por cento e especificidade de 74,5 por cento.

CONCLUSÃO:

Entrevista Clínica Estruturada para Distúrbios do Humor apresenta boa validade e reliabilidade. Escore de mania igual ou superior a 30 adequadamente diferencia transtornos bipolares de depressão unipolar.
