Background: The COVID-19 pandemic is a novel population-level stressor. As such, it is important to examine pandemic-related changes in mental health and to identify which individuals are at greatest risk of worsening symptoms.Methods: Online questionnaires were administered to 34,465 individuals in the UK, recruited from existing cohorts or via social media. Around one third (n = 12,718) with prior diagnoses of depression or anxiety completed pre-pandemic mental health assessments, allowing prospective investigation of symptom change. We examined changes in depression, anxiety and PTSD symptoms using prospective, retrospective and global ratings of change assessments. We also examined the effect of key risk factors on changes in symptoms. Research in contextEvidence before this study We conducted a literature search (PubMed, Scopus) with the terms "mental*" or "psychiatr*" and "covid*" or "coronavirus" published before 8th February 2021. This resulted in 4,573 unique references, but only 15 longitudinal studies examining changes in symptoms of mental health conditions from before to during the COVID-19 pandemic. Results to date are mixed. Some studies found increases in mental distress, some found increases in either depression or anxiety, and others saw no observable change in symptoms.Examining individual-level risk factors, heightened vulnerability to worsening mental health during the pandemic has been demonstrated among young people, females, individuals with lower incomes/financial problems and among health care or key workers. Only one previous study used a large sample with prior mental health diagnoses to examine changes in anxiety and depression. This study showed that having a prior mental health diagnosis was associated with higher levels of perceived worsening of mental health but, when examining actual prospectively measured symptoms, a prior mental health diagnosis was actually associated with a lower likelihood of symptom worsening, compared to no prior diagnosis. This discrepancy across measures requires further investigation in order to understand the nature of changing mental health during the COVID-19 pandemic. Added value of this studyThis study prospectively examined changes in symptoms of depression, anxiety and PTSD in a large UK-based sample of individuals with prior depression or anxiety. Analyses were supplemented with data from additional cohorts to examine individual difference risk factors with greater statistical power. Inclusion of both prospectively measured and retrospectively estimated changes in symptoms, as well as ratings of perceived change in mental health, allowed closer examination of discrepancies in subjective experience versus actual objective change in symptoms.people who are students or are unemployed. Additionally, discrepancies in estimated symptom change across prospective and retrospective measures highlight the importance of using prospectively collected data to examine longitudinal changes.
Objective: The disruption caused by the COVID-19 pandemic has been associated with poor mental health, including increases in eating disorders and self-harm symptoms. We investigated risk and protective factors for the new onset of these symptoms during the pandemic. Method: Data were from the COVID-19 Psychiatry and Neurological Genetics study and the Repeated Assessment of Mental health in Pandemics Study (n = 36,715).Exposures were socio-demographic characteristics, lifetime psychiatric disorder, and COVID-related variables, including SARS-CoV-2 infection/illness with COVID-19.We identified four subsamples of participants without pre-pandemic experience of our outcomes: binge eating (n = 24,211), low weight (n = 24,364), suicidal and/or
Background While studies from the start of the COVID-19 pandemic have described initial negative effects on mental health and exacerbating mental health inequalities, longer-term studies are only now emerging. Method In total, 34 465 individuals in the UK completed online questionnaires and were re-contacted over the first 12 months of the pandemic. We used growth mixture modelling to identify trajectories of depression, anxiety and anhedonia symptoms using the 12-month data. We identified sociodemographic predictors of trajectory class membership using multinomial regression models. Results Most participants had consistently low symptoms of depression or anxiety over the year of assessments (60%, 69% respectively), and a minority had consistently high symptoms (10%, 15%). We also identified participants who appeared to show improvements in symptoms as the pandemic progressed, and others who showed the opposite pattern, marked symptom worsening, until the second national lockdown. Unexpectedly, most participants showed stable low positive affect, indicating anhedonia, throughout the 12-month period. From regression analyses, younger age, reporting a previous mental health diagnosis, non-binary, or self-defined gender, and an unemployed or a student status were significantly associated with membership of the stable high symptom groups for depression and anxiety. Conclusions While most participants showed little change in their depression and anxiety symptoms across the first year of the pandemic, we highlight the divergent responses of subgroups of participants, who fared both better and worse around national lockdowns. We confirm that previously identified predictors of negative outcomes in the first months of the pandemic also predict negative outcomes over a 12-month period.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
