Resumo: | OBJECTIVE To assess the internal consistency of the measurements of the Self-Reporting Questionnaire (SRQ-20) in different occupational groups. METHODS A validation study was conducted with data from four surveys with groups of workers, using similar methods. A total of 9,959 workers were studied. In all surveys, the common mental disorders were assessed via SRQ-20. The internal consistency considered the items belonging to dimensions extracted by tetrachoric factor analysis for each study. Item homogeneity assessment compared estimates of Cronbach’s alpha (KD-20), the alpha applied to a tetrachoric correlation matrix and stratified Cronbach’s alpha. RESULTS The SRQ-20 dimensions showed adequate values, considering the reference parameters. The internal consistency of the instrument items, assessed by stratified Cronbach’s alpha, was high (>; 0.80) in the four studies. CONCLUSIONS The SRQ-20 showed good internal consistency in the professional categories evaluated. However, there is still a need for studies using alternative methods and additional information able to refine the accuracy of latent variable measurement instruments, as in the case of common mental disorders. |

OBJETIVO Avaliar a consistência interna das medidas do Self-Reporting Questionnaire (SRQ-20) em diferentes grupos ocupacionais. MÉTODOS Realizou-se estudo de validação com dados de quatro inquéritos de grupos de trabalhadores, utilizando procedimentos metodológicos semelhantes. Foram estudados 9.959 trabalhadores. Em todos os inquéritos, os transtornos mentais comuns foram avaliados por meio do SRQ-20. A consistência interna considerou os itens pertencentes às dimensões extraídas por análise fatorial tetracórica, para cada estudo. A avaliação da homogeneidade dos itens comparou estimativas alpha de Cronbach (KD-20), o alpha aplicado a uma matriz de correlações tetracóricas e do alpha de Cronbach estratificado. RESULTADOS As dimensões do SRQ-20 apresentaram valores adequados, considerando os parâmetros de referência. A consistência interna dos itens do instrumento, avaliada pelo escore do alpha de Cronbach estratificado, foi elevada (>; 0,80) nos quatro estudos. CONCLUSÕES O SRQ-20 apresentou boa consistência interna nas categorias profissionais avaliadas. Entretanto, ainda são necessários estudos que utilizem métodos alternativos e informações adicionais que possam refinar a precisão dos instrumentos de mensuração de construtos latentes, como no caso dos transtornos mentais comuns.
