The association between childhood emotional maltreatment and body dissatisfaction has been widely identified. However, the explanatory mechanisms for this association remain unclear. Guided by the Stress Process Model, the present study tested the potential mediating roles of self-compassion and body surveillance in the associations between emotional maltreatment (i.e., emotional abuse and neglect) and body dissatisfaction. Three-wave, self-report survey data were collected from 668 Chinese young adults (66.8 % female, M = 19.96 years old, SD = 1.25) with a 6-month between-wave interval. Results demonstrated that childhood emotional neglect (recalled at Time 1) was positively associated with body dissatisfaction (at Time 3) through a serial mediating pathway from self-compassion (at Time 1) to body surveillance (at Time 2). In contrast, no links involving childhood emotional abuse were identified. Findings suggest that the compromised emotion regulation capacity related to self-care and the subsequent self-objectification could be key processes through which childhood emotional deprivation would be positively associated with later body dissatisfaction. Accordingly, prevention and intervention efforts aimed at combating young adults’ body image issues with early adversity of emotional deprivation could integrate emotion regulation training (that can enhance self-care) and cognitive-behavioral techniques (that may reduce body surveillance) into extant programs to enhance effectiveness.
