BACKGROUND Adolescents exposed to maternal depression are more vulnerable to depressive symptoms. Less is known on the mediating role of children's self-worth construction processes, particularly those related to physical appearance. This study proposes and tests appearance contingent self-worth (ACSW) as a mediator linking depressive symptoms across generations. METHODS Our sample included 1,420 participants of the Great Smoky Mountain Study. Offspring depressive symptoms were prospectively assessed with DSM-IV for both the adolescent period (13-16) and adulthood period (19-26). Maternal depression was screened with the Short Mood and Feelings Questionnaire when the child was 13-16 years old. We used gender-stratified structural equation model in which offspring ACSW in adolescence and adulthood were specified as mediators linking maternal depression and offspring depressive symptoms in adolescence and adulthood, respectively. Mediation was tested using bias-corrected bootstrapped standard errors. RESULTS ACSW is associated with higher levels of depressive symptoms in both adolescent and adult females and males, but the link between maternal depressive symptoms and ACSW is only significant among females. ACSW partially mediates the effects of maternal depressive symptoms on adolescent and adult depressive symptoms in girls. LIMITATIONS Measurement of maternal depression was not based on diagnosis. Generalizability is limited due to the regional sample. CONCLUSION Our findings provide evidence that daughters of depressed mothers may stake their self-worth on body image, which may partially explain some of their higher susceptibility to depression.
