RESUMO

Science in general needs each time more instruments that can supply measurable and replicable objectives. The objectives of this research were to elaborate and to validate a scale of occupational stressors for employees of the production line, carrying out content validation, construct validation, convergent validation, precision evaluation and scale normalization. 214 employees were the participants of the research all of whom work in the production line of several companies of the Alto do Tiete region. The sample was divided in three groups (G1, G2, and G3). G1 was composed of 10 employees for a pilot study, G2 was composed of 214 employees for the validation of the scale and G3 was composed of 40 employees who participated in the retest. The materials used were a list with 41 stressors in the initial version of the scale, the scale of occupational stressors with 36 items already after the pilot study was carried out, the Job Content Questionnaire (JCQ) for the convergent validity and the Inventory of Symptoms of Stress Lipp (ISSL). Also, it made use of terms of consent and authorizations whenever necessary. The results demonstrated high and positive correlations in the precision of the scale (p <0.01), tendency to the convergent validity (p <0.01) validity of concurrent criterion (p<0.01 and p <0,005). In relation to the normalization the results showed no evidence of significant differences between age and level of schooling and the scores of the scale of stressors. This demonstrates the universality and practicity, important in system of numerical counting. It was concluded that the scale of occupational stressors of production line presented high coefficient of precision, internal consistency e temporal stability and it was possible to reach the objective of content validity, construct and convergent validity, demonstrating to be capable of identifying occupational stressors of production line. The normalization needs new studies to be carried out with the scale, increasing the number of participants or carrying out a study with random sample, so that bias concerning norms and standardization does not occur.
