Qualidade de vida no trabalho e sua associação com o estresse ocupacional, a saúde física e mental e o senso de coerência entre profissionais de enfermagem do bloco cirúrgico / Quality of Working Life and its association with occupational stress, physical and mental health and sense of coherence among nursing professionals in surgical settings.

The following hypotheses were tested in this study: H1- after controlling for sociodemographic and professional variables, adding occupational stress, anxiety and depression will meaningfully contribute to reduce the measures of Quality of Working Life (QWL); and H2 after controlling for socio-demographic and professional variables, anxiety and depression, adding sense of coherence (SOC) will contribute to increase the QWL measure. This observational, descriptive, correlational and cross sectional study aimed to evaluate QWL, the profile of physical and mental health, the presence of occupational stress and SOC among nursing professionals working in surgical settings (BC). In total, 211 nursing professionals participated in this study. Six instruments were used for data collection: socio-demographic and professional characterization, Visual Analogue Scale for QWL, Job Stress Scale, Hospital Anxiety and Depression Scale (HADS), Standardized Nordic Questionnaire and Antonovskys Sense of Coherence (SOC) Scale. In general, the scales obtained acceptable values for Cronbachs Alpha, which varied from 0.54 to 0.75 on the Job Stress Scale. HADS-Anxiety obtained 0.79 and HADS-Depression 0.77 for Cronbachs Alpha, while the SOC reached an internal consistency score of 0.87. Among the participants, most were nursing auxiliaries (62,6%), female (86,7%) and married (54,0%), with average age of 40 years. The average time of work at the BC was 9.3 (S.D.=8.0) years. Regarding assessment of QWL, the average score obtained for the total sample was 58.9 (S.D.=27.7), in a possible range from zero to 100, showing that workers were fairly satisfied with their quality of life at work. The dimensions (Demand, Control and Social Support) of occupational stress obtained mean scores, i.e. 14.8 (S.D.=2.4), 16.5 (S.D.=2.3) and 18.7 (D.P.=2.8), respectively. Among the participants, 115 (54.5%) were in the group of intermediate exposition to occupational stress. Regarding evaluation of anxiety and depression, the average anxiety score was 6.3 (S.D.=3.7) and average depression 5.2 (S.D.=3.3), in a possible range from zero to 21. It was also shown that, among nursing professionals, 66 (31.3%) presented symptoms of anxiety and 51 (24.2%) symptoms of depression. The highest annual prevalence of musculoskeletal disorders was found in the lower back region (n=82; 38.9%) and in the region of the shoulders (n=80; 37.9%). The SOC score for the 203 nursing professionals who answered this instrument was144.6 (S.D.=22.6), in a possible range from 29 to 203. The QWL measure showed a statistically significant association with the variables kind of institution (p=0.003), monthly income (p=0.006), choice of place of work (p=0.01), presence of occupational stress (p=0.001), presence of anxiety (p=0.008), depression (p=0.05) and musculoskeletal disorders in the region of the shoulders (p=0.00), lumbar region (p=0.00) in the last 12 months and in the lumbar region in the last seven days (p=0,01). The SOC score presented a statistically significant association with kind of institution (p=0.03), having a second job (p=0.00), monthly income (p=0.01), presence of occupational stress (p=0.029), presence of anxiety (p=0.000) and depression (p=0.000). The study reasserted that adding occupational stress and mood disorders contributed to a decrease in QWL among nursing professionals in BC, although it was not confirmed that the addition of SOC could contribute to increase these workers QWL.
