Impact of the COVID-19 pandemic on adults accessing specialist psychiatric care: A cross-sectional Canadian analysis.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe COVID-19 outbreak presented significant psychological challenges, placing individuals with pre-existing psychiatric conditions at disproportionate risk. Identifying the pandemic-related factors driving mental health outcomes in this population is essential to inform targeted interventions during future public health crises.
objectivesTo examine associations between COVID-19-related stressors and psychological symptom severity among Canadian adults with pre-existing mental health conditions during the first two years of the pandemic.
methodsThis cross-sectional study administered a web-based survey to outpatients accessing specialist psychiatric services in Toronto, Canada, between May 2020 and March 2022, aligning with the first five COVID-19 infection "waves" in the region. A series of linear regression models assessed associations between pandemic-related factors (COVID-19 fears, FCV-19S; consumed pandemic-related media; coping responses, Brief-COPE) and symptoms of anxiety (GAD-7) or depression (PHQ-9).
results362 participants completed the self-report survey (70% female, mean age 33.8 ± 11.7). Anxiety (60.2%) and depression (59.1%) were the most frequently reported pre-existing psychiatric conditions. Depressive and anxious symptoms met thresholds for "moderate" severity during all five pandemic waves. Greater fear of COVID-19 was associated with increased symptoms of depression (β = 0.12, 95% CI: 0.01, 0.22) and anxiety (β = 0.25, 95% CI: 0.16, 0.35). Avoidant and emotion-oriented coping predicted increased psychological symptoms (p < .001), while problem-focused coping was associated with lower depression scores (β = -0.15, 95% CI: -0.28, -0.02). Frequency of pandemic-related media consumption showed no significant association with any psychological symptoms (p > .05).
conclusionsCanadians with pre-existing mental health conditions experienced persistently elevated psychological symptoms throughout the first two years of the COVID-19 pandemic. COVID-related fear and maladaptive coping emerged as key drivers of symptom severity, while problem-focused coping showed a protective effect, suggesting modifiable treatment targets. Findings underscore the importance of interventions targeting fear attenuation and adaptive coping to protect psychiatric patients during a prolonged public health crisis. Future research should extend investigations globally to determine the broader mental health impact of pandemic stressors in patient populations. Ultimately, findings support the integration of sustained psychological support within emergency response protocols to mitigate the psychological burden of future pandemics and health crises.
