Character strengths predicted well-being and mental health over a 13-month pandemic period, with positive affect emerging as the primary mediator and goodness, interpersonal, and fortitude strengths yielding the strongest effects.
Key Findings
Results
A single general factor of character strengths predicted mental health outcomes over a 13-month period during the COVID-19 pandemic.
Sample consisted of N = 146 participants who completed online measures at two time points separated by 13 months.
Character strengths were measured alongside mental health, life satisfaction, affect, and post-traumatic growth.
The general character factor predicted later mental health, life satisfaction, affect, and post-traumatic growth.
The study used a longitudinal design with structural equation modeling to test direct and mediated pathways.
Results
Only the affective components of well-being, especially positive affect, mediated the relationship between character strengths and mental health.
Both life satisfaction and post-traumatic growth were predicted by character strengths but did not emerge as significant mediators.
Positive affect was identified as the primary mediating mechanism between character strengths and mental health.
The mediation model was tested with the general character factor as predictor and mental health as the outcome.
These findings suggest character strengths contribute to mental health specifically through fostering affective resilience.
Results
When examining five distinct character strengths factors separately, the majority predicted higher well-being and better mental health over time.
Five character strengths factors were tested as predictors in a second set of models, replicating the mediation structure.
Goodness, interpersonal, and fortitude strengths yielded the strongest effects on well-being and mental health.
The majority of the five factors predicted both well-being outcomes and mental health longitudinally.
Results suggest differential predictive value across the five character strength domains.
Discussion
Character strengths were conceptualized as stable psychological resources that contribute to sustainable well-being in the context of adversity.
The study framed its findings in relation to Sustainable Development Goal 3 (Good Health and Well-being).
Character strengths were described as promoting 'affective resilience in the face of adversity.'
The longitudinal design spanning 13 months during the COVID-19 pandemic was used to assess stability and predictive power of character strengths.
The authors identified the need to study 'stable psychological resources that promote sustainable well-being' as motivation for the study.
Results
Post-traumatic growth was predicted by character strengths but did not serve as a mediator between character strengths and mental health.
Post-traumatic growth was included as one of the outcome and potential mediator variables alongside life satisfaction and affect.
Character strengths significantly predicted post-traumatic growth over the 13-month period.
Despite being predicted by character strengths, post-traumatic growth did not mediate the character-mental health relationship.
Life satisfaction similarly was predicted but did not mediate, contrasting with positive affect which did mediate.
