Background: Recent time-dependent analyses of stress-related disorders have identified heterogeneity of trajectories and their modifying factors. While psychiatric patients are vulnerable to stress events, it is unclear how psychiatric conditions in the general population modulate subsequent event-related distress trajectories.
Methods: Using a longitudinal online survey from before the COVID-19 pandemic to post-pandemic follow-ups (n = 3815 Japanese adults) and a latent growth mixture model, we identified four trajectories of pandemic-related stress symptoms: resilient, chronic, mild chronic, and early response.
Article Synopsis
- The COVID-19 pandemic has significantly impacted the mental health of both infected and uninfected individuals, with previous studies often focusing on single psychiatric disorders.
- A study involving 2,274 Japanese citizens used surveys to analyze psychiatric symptoms across multiple points in time and identified four key areas affected: general psychiatric burden, social withdrawal, alcohol-related issues, and depression/anxiety.
- Results indicated that the initial phase of the pandemic saw peaks in general psychiatric burden and depression/anxiety, exacerbated by economic stress, while social withdrawal peaked later, highlighting the need for adaptable mental health strategies throughout the pandemic's progression.
