Resumo(s)
O ruído tem sido amplamente estudado como sendo um fator de risco ocupacional devido ao seu impacto fisiológico negativo na saúde dos trabalhadores. No entanto, há ainda poucas investigações que combinem a questão da exposição ao ruído ocupacional e os seus efeitos psicológicos. Neste sentido, o presente estudo procura compreender a relação entre a perceção de ruído ocupacional (PRO) e o burnout, investigando também o papel moderador da vulnerabilidade ao stress (VS) e do estilo de vida (EV). A amostra utilizada neste estudo foi constituída por 85 trabalhadores expostos a ruído ocupacional em ambientes industriais, 43 do sexo feminino e 42 do sexo masculino, com idades compreendidas entre os 19 e os 66 anos. Os dados foram obtidos através de questionários e os resultados analisados através de análises de correlação e moderação, tendo sido confirmada uma das hipóteses colocadas. Os resultados demonstram uma relação entre a VS e o burnout, em que níveis mais elevados de VS se associam a maiores níveis de burnout. As restantes hipóteses foram refutadas, chegando-se à conclusão de que não existe uma associação significativa entre a PRO e o burnout, nem entre o EV e o burnout. Também não se confirma o papel moderador da VS e do EV, na relação entre a PRO e o burnout. Foi ainda realizada uma análise suplementar incluindo o ruído objetivo aproximado, onde se concluiu que existe uma relação entre o ruído objetivo e os níveis de burnout, isto é, níveis de ruído mais elevados relacionam-se com valores mais elevados de burnout. Os resultados demonstram que a VS e o EV moderam a relação entre o ruído objetivo e o burnout, sendo que esta relação é apenas significativa para os indivíduos mais vulneráveis ao stress e com EV menos saudáveis. A principal implicação prática desta investigação é alertar para o impacto que o ruído ocupacional tem na saúde psicológica dos colaboradores, sendo de extrema importância o desenvolvimento de estudos mais aprofundados acerca da exposição ao ruído ocupacional e seus efeitos psicológicos, bem como estudos que englobem estas quatro variáveis conjuntamente.
Noise has been widely studied as a factor of occupational risk due to its negative physiological impact on employees’ health. However, there are still few studies that combine the issue of exposure to occupational noise and its psychological effects. In this line, this study aims to investigate the relation between perception of occupational noise (PRO) and burnout, exploring also the possible moderating role of vulnerability to stress (VS) and lifestyle variables (EV). The sample used in this study was composed of 85 employees, 43 females and 42 males aged 19-66, exposed to occupational noise at industrial environments. The data were obtained through questionnaires and the results were analyzed through correlation and moderation analyses. One of our hypotheses was confirmed. Thus, there was a significant association between VS and burnout, in which higher levels of VS were associated with higher levels of burnout. The remaining hypotheses were not confirmed as no significant association was found between PRO and burnout, neither between EV and burnout. The moderating role of VS and of EV in the relation between PRO and burnout was also not confirmed. A supplementary analysis was also carried out including the approximate objective noise, and there was a significant association between objective noise exposure and burnout levels, that is, higher noise levels were associated with higher levels of burnout. The results show that SV and VS moderate the relationship between objective noise and burnout, and this relationship is only significant for individuals who are more vulnerable to stress and with less healthy VS. The main practical implication of this study is to alert to the impact that occupational noise can have on the psychological health of employees, being extremely important the development of more in-depth studies about occupational noise exposure and its psychological effects, as well as studies that included the four variables simultaneously.
