Resumen

OSSA, Ximena et al. Risk perception of occupational exposure to silica: Construction and validation of a questionnaire in Chile. Cienc Trab. [online]. 2018, vol.20, n.62, pp.90-96. ISSN 0718-2449.  http://dx.doi.org/10.4067/S0718-24492018000200090.

Introduction:

Silicosis is a progressive lung disease, irreversible, but potentially preventable. Knowing the perception of risk in workers exposed to silica is necessary to intervene and reduce the incidence of silicosis and other related diseases. The objective of this study was to validate a Questionnaire of risk perception of occupational expo sure to silica (CuPREOS) in exposed workers, in different work activities in Temuco, Chile.

Material and method:

A stage of explo ration with phenomenological/naturalist approach allowed to create categories of first and second order, which ended in a first version of the instrument. The second stage included exploratory and con firmatory factor analysis.

Results:

two underlying dimensions were revealed: a) evidence of risk, in which worker states to evaluate signals of alarm and b) absence of risk, in which he weighs aspects that counteract the previous ones. Both set up the conceptual frame work that sustain the CuPREOS of 9 items/questions, with a reliabil ity of 0.84 (Cronbach alfa). The confirmatory analysis indicators show a good fit of the model.

Discussion:

the perception of risk is a construct involving social and cultural complexities, its measurement should be simple and practical; its knowledge would enable more effective decision-making in prevention and intervention.
