The beneficial role of personality in preserving well-being during the pandemic: A longitudinal population study.

BACKGROUND

The COVID-19 pandemic resulted in increased rates of mental health problems. We examined the possible role of the personality characteristic, Locus of Control (LOC), in moderating pandemic-induced stress.

METHODS

The UK-based Avon Longitudinal Study of Parents & Children (ALSPAC), 7021 adults (mean ages: women 57.6 (SD = 4.48); partners 60.5 (SD = 5.36)) responded to a 2020 questionnaire which included a generalised measure of LOC. Between March 2020-January 2021, questionnaires focussed on the pandemic were administered, which included measures of mental health. Over 60 % of respondents completed questionnaires at three timepoints of interest.

RESULTS

In those with an internal LOC higher rates of positive well-being and reduced likelihood of anxiety and depression were shown compared to those who were external, e.g. after adjustment for socioeconomic/demographic factors mean differences in well-being score for internal compared with external women was +2.01 (95%CI +1.02,+2.10) p = 0.0001; for their partners +2.52 (95%CI +1.22,+3.82) p = 0.0002. External women were more likely than internals to have depression (adjusted OR 3.41 [95%CI 1.77,6.57] p < 0.0005.

LIMITATIONS

Attrition is a problem in this 30-year-old longitudinal cohort. Those still participating are more likely to have higher education and SES levels, be female and have an internal LOC. This population suffers from a lack of ethnic diversity.

CONCLUSIONS

Having an internal LOC positively moderated the effects of pandemic-induced stress on the frequency of anxiety and depression in middle-age. Programmes geared to raise internality and coping strategies may have long-term benefits on well-being in stressful situations, especially for women and frontline health professionals.
