Predictors of Psychosomatic Health during the first COVID-19 Outbreak in Greece. A Multiple Linear Regression Analysis in an Epidemiological Sample of 1,156 Individuals
Background: Between March 23 and May 4, 2020, the Greek government established an economic and social ‘lockdown’ to prevent the spread of COVID-19. It was hypothesized that the unsafe environment activated the stress response of the Greeks during that time, while existing literature supports the development of psychosomatic disorders. Aim: The research question is whether six biopsychosocial variables predict psychosomatic symptoms of the Greek general population during the ‘lockdown’. Methods & Materials: A convenient sample of 1,158 -of whom 2 were excluded from the final analysis- Greeks participated electronically during the ‘lockdown’. Pearson’s r and a linear-multiple regression analyses were chosen to test the hypothesis. The participants answered a series of demographic questions, while the rest variables were measured through the following self-reported psychometric tools: ‘psychosomatics’ [PSSQ-29], ‘acute stress’ [ASDS], ‘psychological resilience’ [NMRQ], and ‘satisfaction with life’ [SWLS]. Results: Between the significant predictors, the first to appear is ‘acute stress’ (β= .66, p< .001), while ‘psychological resilience’ (β= .21, p< .001), ‘satisfaction with life’ (β= .06, p= .001) and ‘age’ (β= .04, p= .025) follow hierarchically. Discussion: The findings are consistent to the background literature and previous relevant COVID-19 studies, with the exception of the findings regarding ‘gender’ -which was not found significant in the weightings-. Conclusion: The model predicts the criterion with a large effect. The study is overall confirmatory to previous COVID-19 research regarding domestic general population, while the need for European studies that would include positive components on psychosomatic health is highlighted.
