Reprodutibilidade de uma escala para avaliar a percep??o dos trabalhadores quanto ao ambiente e às condi??es de trabalho

摘要

OBJECTIVE: To introduce the scale Profile of Work Environment and Working Conditions and assess its degree of test-retest reliability. METHODS: The scale was submitted to three experts for face and content validity, and pilot-tested with a group of industry workers. For reliability analysis, the instrument was applied twice, one week apart, to 122 industrial workers, males and females, with different educational backgrounds. Average age was 29 years (SD=8.44). The scale included five components, with three items in each one. The Kappa coefficient was utilized to compare test and re-test agreement, both globally and for each component of the scale. RESULTS: Kappa coefficient for the entire scale was 0.64, with 77.6% agreement between applications. CONCLUSION: the scale was structured following evidences from the literature and experts' analyses, being easy to respond by workers, in a short period of time. The reliability coefficients of the scale indicated that the test has good (substantial) level of reprodutibility when applied to workers of both sexes, and diverse types of jobs, but with educational level above elementary school.
