Trajectories of anxiety, depression, and posttraumatic stress among healthcare workers during the COVID-19 pandemic: one-year monthly follow-up.

Abstract

Objectives: This study aimed to assess longitudinal patterns of anxiety, depression, and posttraumatic stress symptoms, as well as their predictors, in a reference hospital workforce during the first two waves of the pandemic in Brazil.

Methods: Data were collected between July 2020 and June 2021 (N = 1,078). Anxiety, depression, and posttraumatic stress symptoms were assessed using three self-report scales (GAD-7, PHQ-9, IES-R). Predictor analysis included COVID-19-related events, fear of COVID-19, and institutional support. Statistical analysis involved linear mixed models and local polynomial regressions.

Results: Anxiety and depression showed a tendency towards increased reactivity, while posttraumatic stress presented a tendency towards reduction with less fluctuation. Predictor analysis showed that higher levels of institutional support were associated with a reduced risk of all mental health outcomes. Conversely, greater fear of COVID-19 was positively associated with all of them.

Conclusions: Our findings underscore the importance of allocating enhanced attention and resources to effectively address pressing personal health challenges, emphasizing the significance of organizational support and continuous monitoring of emotional distress.
