Childhood Maltreatment and Gratitude: A Multilevel, Meta-Analytic Review

Abstract

During the past decade, research on the association between childhood maltreatment (CM) and gratitude has been accumulating, but there is a lack of systematic, quantitative evaluation of existing literature. The present systematic review aims to fill this gap by conducting a three-level meta-analysis. After a comprehensive search in five English and three Chinese databases, we retrieved 33 effect sizes from 16 studies with a total sample of 13,818 participants. The results showed that CM (aggregated across forms) was negatively and moderately linked to gratitude ( r = −.311, 95% CI [−0.382, −0.235], p < .001). Childhood neglect (i.e., physical and emotional neglect) exhibited more substantial effects on gratitude than emotional abuse, while the effects of childhood physical and sexual abuse were insignificant. In addition, the mean effect sizes were larger in studies with younger samples. However, the effect did not vary as functions of CM measurement, methodological rigor, whether the sample included college students only, publication type, or region of the sample. Last, we highlighted the limitations of existing research, proposed agendas for future studies, and discussed practical implications.
