Parents are integral stakeholders in children’s health and development, and yet there is a dearth of research on parental attitudes and parents’ personal weight and eating psychopathology, which have the potential to influence pediatric obesity and eating disorder treatments meaningfully. Overvaluation of weight/shape is a core concept in eating-disorder assessment and treatment defined as self-evaluation excessively based on weight/shape, which research has demonstrated to be clinically important psychopathology. A novel and related concept, parental overvaluation of weight/shape, could be defined as parents’ self-evaluation unduly based on their child’s weight/shape, yet this concept has not been studied and its clinical importance is unknown. The aim of this study was to examine the distinctiveness of parental overvaluation of weight/shape from personal overvaluation of weight/shape, and to examine associations of parental overvaluation with parents’ psychopathology and children’s weight and eating behaviors. The current study examined differences among parents with (n=134) and without (n=872) parental overvaluation using a cross-sectional design. Parental overvaluation was more common among parents with binge-eating disorder and bulimia than obesity and healthy-weight. Parental overvaluation was modestly associated with personal overvaluation. Parents with and without parental overvaluation differed on personal eating-disorder psychopathology and children’s weight and eating behaviors. Importantly, differences remained after adjusting for personal overvaluation and child BMI. This study highlights a novel construct—parental overvaluation—associated with, but distinct from, parental eating disorders and personal overvaluation. Parental overvaluation may warrant clinical attention among parents seeking pediatric obesity or eating-disorder treatment, or treatment for personal eating disorders.
