The dynamics of Appraisal II: a meta-analysis of the relationship between fortitude and the indices of psychological well-being

Identifying the factors that contribute to differential vulnerability in the face of adversity is key to psychology fulfilling its mandate as a helping profession. One such factor, fortitude, which is described as the psychological strength to manage adversity and to stay well, has consistently been linked to psychological well-being. The objective of the research was to statistically integrate studies examining the relationship between fortitude and the indices of psychological well-being by using a meta-analysis. We used a random-effects model for the meta-analysis. In addition to the overall effect size, we examined publication bias and the moderating role of age and methodological quality. We also performed a subgroup analysis to compare between studies with positive and negative indicators of psychological well-being. In addition, we used robust variance estimation to account for effect-size dependencies, as some studies have reported more than one correlation coefficient. A total of 13 studies reporting 35 correlation coefficients pertaining to the relationship between fortitude and the indices of psychological well-being were extracted. The meta-analysis revealed a significant overall effect (r = .44, p < .001). The results also indicated that age and methodological quality did not influence the effect size. Subgroup analysis indicated that the overall effect size for studies that used positive indicators (r = .49, p < .001) was higher than that for studies that used negative indicators (r = .36, p < .001). In addition, no visual or statistical evidence of publication bias was observed. The robust variance estimation results also confirmed that the effect-size dependencies did not influence the overall effect size. The study results provide strong evidence regarding the association between fortitude and psychological well-being. This finding has several implications for promoting mental health and suggests that interventions aimed at building fortitude can be leveraged to mitigate psychological distress.
