Abstract
OBJETIVO: Discutir aspectos metodológicos da estratégia de identificação de casos psiquiátricos, em duas etapas, em estudos epidemiológicos. MÉTODOS: Analisa-se a metodologia utilizada no Estudo Multicêntrico de Morbidade Psiquiátrica do Adulto realizado em três cidades brasileiras, entre 1990-1991. Na primeira etapa do citado estudo, uma amostra aleatória (6.740 indivíduos) da população foi selecionada e submetida a um rastreamento com o Questionário de Morbidade Psiquiátrica do Adulto -- QMPA. Na segunda etapa, uma subamostra (775 indivíduos) foi selecionada e submetida ao Inventário de Sintomas do DSM-III (Diagnostic and Statistical Manual of Mental Disorders), aplicado por psiquiatras e psicólogos treinados, para confirmação-diagnóstica. RESULTADOS: São descritos os procedimentos empregados para a estimativa das prevalências, mostrando que o fraco desempenho da escala de rastreamento não compromete o método. CONCLUSÃO: A vantagem da metodologia é a de corrigir as distorções apresentadas pelos instrumentos atuais de identificação de casos psiquiátricos.
OBJECTIVE: To discuss methodological aspects of the two stages in the identification of psychiatric cases in epidemiological studies. METHODS: Analyze the methodology used in the Multicentric Psychiatric Morbidity Study, which was conducted in three Brazilian cities (São Paulo, Brasília and Porto Alegre). In the first stage of that study, a random sample (6,740 individuals) of the population was drawn and all the participants were screened with the Questionnaire of Psychiatric Morbidity of the Adult (QMPA). In the second stage, a sample (775 individuals) of this population was drawn and these individuals were submitted to the Inventory of Symptoms of DSM-III, carried out by psychiatrists and trained psychologists. RESULTS: The study procedure for estimating the prevalence is described in details, showing that though the screening scales are a weak tool, they don't interfere with the methodology. CONCLUSION: The advantage of this methodology is to correct any distortions caused by the current tools used in the identification of psychiatric cases.
