Psychometric properties of the Providers Survey in the Brazilian context of mental health: a validation study.

BACKGROUND

Precisely determining the aspects related to an instrument's validity and reliability measures allows for greater assurance of the quality of the results.

OBJECTIVES

To analyze the psychometric properties of The Providers Survey in the Brazilian context of mental health services.

DESIGN AND SETTING

The instrument validation study was conducted in Montes Claros, Minas Gerais, Brazil.

METHODS

The validation study was conducted using the Consensus-based Standards for the Selection of Health Measurement Instruments checklist to analyze its validity and reliability.

RESULTS

A committee of expert judges performed content validation after which the Content Validity Index was calculated. Construct validation took place through Exploratory Factor Analysis using the Kaiser-Meyer-Olkin Test criterion and Bartlett's Sphericity Test. Reliability was verified using test-retest reliability. The significance level adopted for the statistical tests was 5% (P < 0.05). The final instrument comprised 54 questions. The Content Validity Index was 97%. Exploratory Factor Analysis identified a Kaiser-Meyer-Olkin index of 0.901 and Bartlett's Sphericity Test with P < 0.001. We obtained a Cronbach's alpha coefficient of 0.95 and an intraclass correlation coefficient of 0.849.

CONCLUSIONS

The Providers Survey, translated and adapted into Portuguese, was named the Work Assessment Instrument for the Recovery of Mental Health. It presented adequate psychometric properties for evaluating work-related practices for the recovery of psychosocial care network users.
