dc.description.abstract	Stress and anxiety have been consistently linked with impaired memory and decision making ability which can reduce workplace performance. While such impairments pose a risk to nurse performance, hence quality of patient care, research examining the cognitive impact of stress and anxiety in nurses is limited. The present study analysed data from 61 nurses and 51 non‐health professionals. The Depression, Anxiety, Stress Scale (DASS) measured state stress and anxiety levels. Global and domain specific cognitive performance was assessed using the Mini‐mental state exam and Cognistat, respectively. Additionally, a 32 lead electroencephalogram (EEG) montage was also captured as a physiological measure of cognitive performance. Stress was found to be associated with facilitated decision‐making in non‐health professionals (r = 0.37, p = 0.01), and impaired memory performance in nurses (r = ‐0.28, p < 0.05). Anxiety was associated with impaired memory in nurses (r = ‐0.39, p < 0.01) but no such association was observed in non‐health professionals. Analysis of EEG data revealed associations between stress and anxiety, and delta, beta and gamma activity variations, mostly localised to frontotemporal and frontoparietal brain regions. Overall, stress and anxiety are experienced by both non‐health professionals and nurses alike, and may influence cognitive performance in a unique manner for each group. Findings suggest that development and implementation of countermeasure strategies may help preserve nurse performance, and potentially reduce adverse medical events.

Abstract:

Stress and anxiety have been consistently linked with impaired memory and decision making ability which can reduce workplace performance. While such impairments pose a risk to nurse performance, hence quality of patient care, research examining the cognitive impact of stress and anxiety in nurses is limited. The present study analysed data from 61 nurses and 51 non‐health professionals. The Depression, Anxiety, Stress Scale (DASS) measured state stress and anxiety levels. Global and domain specific cognitive performance was assessed using the Mini‐mental state exam and Cognistat, respectively. Additionally, a 32 lead electroencephalogram (EEG) montage was also captured as a physiological measure of cognitive performance. Stress was found to be associated with facilitated decision‐making in non‐health professionals (r = 0.37, p = 0.01), and impaired memory performance in nurses (r = ‐0.28, p < 0.05). Anxiety was associated with impaired memory in nurses (r = ‐0.39, p < 0.01) but no such association was observed in non‐health professionals. Analysis of EEG data revealed associations between stress and anxiety, and delta, beta and gamma activity variations, mostly localised to frontotemporal and frontoparietal brain regions. Overall, stress and anxiety are experienced by both non‐health professionals and nurses alike, and may influence cognitive performance in a unique manner for each group. Findings suggest that development and implementation of countermeasure strategies may help preserve nurse performance, and potentially reduce adverse medical events.
