RESUMO

OBJECTIVE: Bipolar spectrum disorders (BSDs) are prevalent and frequently unrecognized and undertreated. This report describes the development and validation of the Brazilian version of the bipolar spectrum diagnostic scale (B-BSDS), a screening instrument for bipolar disorders, in an adult psychiatric population. METHOD: 114 consecutive patients attending an outpatient psychiatric clinic completed the B-BSDS. A research psychiatrist, blind to the B-BSDS scores, interviewed patients by means of a modified version of the mood module of the Structured Clinical Interview for DSM-IV ("gold standard"). Subthreshold bipolar disorders were defined as recurrent hypomania without a major depressive episode or with fewer symptoms than those required for threshold hypomania. RESULTS: The internal consistency of the B-BSDS evaluated with Cronbach's alpha coefficient was 0.89 (95 percent CI; 0.86-0.91). On the basis of the modified SCID, 70 patients (61.4 percent) of the sample received a diagnosis of BSDs. A B-BSDS screening score of 16 or more items yielded: sensitivity of 0.79 (95 percent CI; 0.72-0.85), specificity of 0.77 (95 percent CI; 0.70-0.83), a positive predictive value of 0.85 (95 percent CI; 0.78-0.91) and a negative predictive value of 0.70 (95 percent CI; 0.63-0.75). CONCLUSION: The present data demonstrate that the B-BSDS is a valid instrument for the screening of BSDs.


OBJETIVO: Transtornos do espectro bipolar (TEB) são prevalentes e comumente subdiagnosticados e subtratados. O presente trabalho descreve o desenvolvimento e a validação da versão brasileira da escala diagnóstica do espectro bipolar (B-EDEB), um instrumento de rastreio para transtornos bipolares, em uma população psiquiátrica adulta. MÉTODO: 114 pacientes consecutivos de um ambulatório psiquiátrico completaram a versão brasileira da B-EDEB. Um psiquiatra pesquisador, cego para os escores do B-EDEB, entrevistou os participantes por meio de uma versão modificada do módulo de transtornos do humor da entrevista clínica estruturada para o DSM-IV ("padrão-ouro"). RESULTADOS: A consistência interna da B-EDEB, avaliada mediante o coeficiente alfa de Cronbach, foi de 0,89 (IC 95 por cento; 0,86-0,91). De acordo com o padrão-ouro, 70 (61,4 por cento) participantes tiveram diagnóstico de TEB. Um escore da B-EDEB de 16 ou mais itens apresentou sensibilidade de 0,79 (IC 95 por cento; 0,72-0,85), especificidade de 0,77 (IC 95 por cento; 0,70-0,83), valor preditivo positivo de 0,85 (IC 95 por cento; 0,78-0,91) e valor preditivo negativo de 0,70 (IC 95 por cento; 0,63-0,75). CONCLUSÃO: Os resultados do presente estudo demonstram que a B-EDEB é um instrumento válido para o rastreio de TEB.

RESUMO

OBJECTIVES: Because bipolar spectrum disorders frequently go unrecognized in clinical practice, sensitive screening tools for bipolar spectrum disorders are much needed. This study was conducted to confirm the validity of the Korean version of the Bipolar Spectrum Diagnostic Scale (BSDS), which was originally designed by Ronald Pies. METHODS: The BSDS, which was translated into Korean by the authors, was administered to patients with known bipolar disorders (N=60) and unipolar depressive disorders (N=27). Using various cut-off scores, we calculated the sensitivities and specificities of the Korean version of the BSDS in order to determine the optimal cut-off score. RESULTS: In this study, a cut-off score of 10 was shown to be optimal, with a sensitivity of 0.73 and a specificity of 0.85, although a cut-off score of 13 was proposed to be optimal by the original authors of the BSDS. CONCLUSION: These results indicate that the Korean version of the BSDS is a valid screening tool for bipolar spectrum disorder.
