Abstract: Background Health and social care workers(HSCWs) are at risk of experiencing adverse mental health (MH) outcomes (e.g., higher levels of anxiety and depression) as a result of the COVID-19 pandemic. This can have a detrimental impact on quality of care, the national response to the pandemic and its aftermath. Aims A longitudinal design provided follow-up evidence on the MH(changes in the prevalence of disease over time) of NHS staff working in a remote health board in Scotland during the COVID-19 pandemic and investigated the determinants of MH outcomes over time. Method A two-wave longitudinal study was conducted from July to September 2020. Participants self-reported levels of depression(PHQ-9), anxiety(GAD-7), and mental well-being(WEMWBS) at baseline and again 1.5 months later. Results The analytic sample of 169 participants, working in community(43%) and hospital(44%) settings reported substantial levels of probable clinical depression, anxiety and low mental well-being(MWB) at baseline(depression:30.8%, anxiety:20.1%, low-MWB:31.9%). Whilst the MH of participants remained mostly constant over time, the proportion of participants meeting the threshold for clinical anxiety increased to 27.2% at follow-up. Multivariable modelling indicated that working with, and disruption due to COVID-19 were associated with adverse MH changes over time. Conclusions HSCWs working in a remote area with low COVID-19 prevalence, reported similar levels of substantial anxiety and depression as those working in areas of the UK with high rates of COVID-19 infections. Efforts to support HSCW MH must remain a priority and should minimize the adverse effects of working with, and the disruption caused by the COVID-19 pandemic.
