Spirituality as a protective factor for chronic and acute anxiety in Brazilian healthcare workers during the COVID-19 outbreak

BACKGROUND: Anxiety symptoms (AS) are exacerbated in healthcare workers (HCWs) during the COVID-19 pandemic. Spirituality is known to protect against AS in the general population and it is a construct that differs from religion. It can be assessed using structured questionnaires. A validated questionnaire disclosed three spirituality dimensions: peace, meaning, and faith. In HCWs we investigated the predictors of chronic anxiety (pre-COVID-19 and during the pandemic) and acute anxiety (only during the pandemic), including spirituality in the model. Then, we verified which spirituality dimensions predicted chronic and acute anxiety. Lastly, we studied group differences between the mean scores of these spirituality dimensions. MATERIAL AND METHODS: The study was carried out in a Brazilian Hospital. HCWs (n = 118) were assessed for spirituality at a single time-point. They were also asked about AS that had started pre-COVID-19 and persisted during the pandemic (chronic anxiety), and AS that had started only during the pandemic (acute anxiety). The subjects without chronic anxiety were subdivided into two other groups: acute anxiety and without chronic and acute anxiety. Forward stepwise logistic regressions were used to find the significant AS predictors. First, the model considered sex, age, religious affiliation, and spirituality. Then, the analysis were performed considering only the three spirituality dimensions. Group means differences in the spirituality dimensions were compared using univariate ANCOVAS followed by T-tests. RESULTS: Spirituality was the most realible predictor of chronic (OR = 0.818; 95%CI:0.752–0.890; p<0.001) and acute anxiety (OR = 0.727; 95%CI:0.601–0.881; p = 0.001). Peace alone predicted chronic anxiety (OR = 0.619; 95%CI:0.516–0.744; p<0.001) while for acute anxiety both peace (OR:0.517; 95%CI:0.340–0.787; p = 0.002), and faith (OR:0.674; 95%CI:0.509–0.892; p = 0.006) significantly contributed to the model. Faith was significantly higher in subjects without AS. CONCLUSION: Higher spirituality protected against chronic and acute anxiety. Faith and peace spirituality dimensions conferred protection against acute anxiety during the pandemic.
