Análise das propriedades psicométricas do instrumento The Providers Survey no contexto brasileiro dos serviços de saúde mental

Abstract

Objective: Analyze the psychometric properties of the instrument The Providers Survey in the Brazilian context of mental health services. Method: This is a methodological study to validate the instrument that used the COSMIN checklist to analyze the characteristics of content validity, construct validity and reliability. Data were collected between December 2019 and January 2020. The sample for content validation had a total of 10 professionals and, for data collection, the items were organized with response options using the Likert scale of 1 to 4 and then the Content Validity Index (CVI) was calculated. Data collection for construct validation took place online using the Qualtrics Survey Software Platform and was verified through Exploratory Factor Analysis (AFE) using the Kaiser-Meyer-Olkin Test (KMO) criterion and Bartlett's Sphericity Test in a sample of 318 respondents. For the reliability analysis, the test-retest was used with a sample of 51 respondents by means of the Cronbach's alpha coefficient (α-Cr) in order to verify the internal consistency and the Intraclass Correlation Coefficient (ICC) to check the stability. The level of significance adopted for the statistical tests was 5%, or, p-value <0.05. All statistical analyzes were performed using the statistical package IBM-SPSS (Statistical Package for the Social Science) software, version 22.0 for Windows. Results: The final instrument presented 54 questions. 97% CVI was obtained. The initial procedures of the Exploratory Factor Analysis identified the Kaiser-Meyer-Olkin index of 0.901 and Bartlett's Sphericity Test with a significance level of p <0.001. After checking the internal consistency, Cronbach's alpha coefficient of 0.95 was obtained. The Intraclass Correlation Coefficient and the correlation between the mean scores at the two moments presented a value of 0.849 (p <0.001). Conclusion: The instrument The Providers Survey, translated and adapted to the Portuguese language, received the name of Work Evaluation Instrument for Recovery in Mental Health (IATRE-SM) and presented adequate psychometric properties for the evaluation of the professionals' practices related to the work for the recovery of users of the psychosocial care network.
