Dr Anna Powell

Dr Anna Powell is a Research Fellow in the School of Psychology at Liverpool John Moores University. Dr Powell co-founded the research group “AlcoLab” along with other LJMU researchers interested in conducting research on the drivers and effects of alcohol use. This group meets informally once a month to discuss their research, grant applications, influential papers within the field, and barriers to / issues to consider when conducting alcohol research.

Dr Powell’s PhD research investigated the relationship between alcohol use and cognitive function, in different contexts. A systematic review examined longitudinal recoverability of cognitive function during abstinence in individuals with an alcohol use disorder, followed by a series of studies that assessed subjective executive function and vibrotactile reaction time in a range of dependent and non-dependent drinkers. Overall, the results showed that 1) cognitive function in several areas can recover in individuals with an alcohol use disorder who maintain abstinence, 2) hazardous drinkers experience poorer subjective executive function, but 3) perform faster during choice reaction time, and 4) impaired choice reaction time is demonstrated during early abstinence in dependent drinkers compared to controls, as is worsening mental fatigue, specifically in outpatients. These results have implications for health providers and policymakers, as hazardous drinkers are subject to alcohol harms despite not being a clinically prioritised group, while outpatients, despite typically fewer complex needs, are experiencing potentially harmful effects of cognitive exertion, so may need more support within their treatment pathway.

Since this time, Dr Powell’s work has expanded to understanding the experiences of other marginalised groups. Indeed, in her current role as a Research Fellow, she is qualitatively investigating the experience of ethnically diverse communities in relation to seasonal influenza vaccinations.
