Sensibilidade e especificidade do Patient Health Questionnaire-9 (PHQ-9) entre adultos da população geral
Open accessAbstract
Com o objetivo de estudar a validade do Patient Health Questionnaire-9 (PHQ-9) no rastreio de episódio depressivo maior na população geral, conduziu-se um estudo de base populacional em Pelotas, Rio Grande do Sul, Brasil. Os domicílios foram sorteados por amostragem em múltiplos estágios, sendo os adultos (> 20 anos) convidados a participar. O padrão ouro foi a entrevista diagnóstica estruturada Mini International Neuropsychiatric Interview (MINI) aplicada por psiquiatras e psicólogos. Tanto o PHQ-9 quanto o MINI foram aplicados no domicílio. Em um total de 447 participantes (191 homens e 256 mulheres) a análise contínua identificou o ponto de corte > 9 como de máxima sensibilidade (77,5%; 61,5-89,2) e especificidade (86,7%; 83,0-89,9). Usando o algoritmo do teste, houve diminuição da sensibilidade para 42,5% (27,0-59,1), enquanto que a especificidade aumentou para 95,3% (92,8-97,2). O PHQ-9 mostrou-se apropriado para rastreamento de episódio depressivo maior. Pela maior sensibilidade, o PHQ-9 pontuado de forma contínua mostrou-se mais adequado do que o algoritmo para rastreamento de episódio depressivo maior na comunidade.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
