“What does not kill you… mutates and tries again.” A study on personality determinants of post-traumatic growth during the COVID-19 pandemic

Introduction . The COVID-19 pandemic was recognized as a collective trauma and as a major threat to mental health. Recent literature focused on the stress symptomatology or post-traumatic stress disorder associated to the COVID-19 exposure. The concept that people have a natural inclination toward growth, even under stressful and threatening events, gathered less attention. Previous research has analyzed antecedents of post-traumatic growth (PTG) with non-conclusive results. Methods . The present research aimed at including findings on PTG from personality traits, i.e., sense of control and self-mastery, and distal condition of nurturance and support received by others, i.e., cognitive and affective well-being. Analyses were based on 4934 interviews with adults (M age = 57.81 years, 55.5% women) from the Swiss Household Panel study. Results . Relationships over time emerged between sense of control and self-mastery on PTG and worries, measured after two years, via the mediation of cognitive and affective well-being. Conclusion . Results come from a large study in a design seldom employed in this type of research and can inform both research and interventions.
