Benefits of Expressive Writing on Healthcare Workers' Psychological Adjustment During the COVID-19 Pandemic

COVID-19 outbroke in Wuhan, China, in December 2019 and promptly became a pandemic worldwide, endangering health and life but also causing mild-to-severe psychological distress to lots of people, including healthcare workers (HCWs). Several studies have already showed a high prevalence of depression, anxiety, and post-traumatic symptoms in HCWs but less is known about the efficacy of psychological interventions for relieving their mental distress. The aims of this study were: (1) to evaluate the psychological adjustment of Italian HCWs during the COVID-19 pandemic; (2) to investigate the efficacy of an expressive writing (EW) intervention, based on Pennebaker's paradigmatic protocol, on their psychological adjustment; (3) to analyze if outcomes of EW vary in function of individual differences (age, gender, marital status, and baseline values of symptoms). Fifty-five HCWs were randomly assigned to one of two writing conditions: EW (n = 30) or neutral writing (NW; n = 25). Psychological adjustment (in terms of ptsd, depression and global psychopathology's symptoms, perceived social support, and resilience) was assessed before and after three writing sessions. Participants who received the EW intervention showed higher improvements in ptsd, depression, and global psychopathology symptoms. Improvements in EW group varied in function of age, gender, marital status, and baseline values: young, men, married participants and those who had higher baseline scores showed a higher reduction of psychological distress symptoms while women, single and those who had lower baseline value showed increased social support, and resilience. In conclusion, the EW intervention had positive effects which varied in function of individual differences on HCWs' psychological health.
