Implicit, explicit, and internalized weight bias and psychosocial maladjustment among treatment-seeking adults

Abstract

Objective Weight bias among weight loss treatment-seeking adults has been understudied. This investigation examined the 1) levels of implicit, explicit, and internalized weight bias among overweight/obese treatment-seeking adults, 2) association between weight bias and psychosocial maladjustment (binge eating, body image, depression), and 3) association between participation in weight loss treatment and changes in weight bias. Methods Fifty-four overweight and obese individuals (BMI ≥ 27) recruited for a weight loss intervention completed measures of depression, body image, binge eating, and implicit, explicit, and internalized weight bias. Results Participants evidenced significant implicit, explicit, and internalized weight bias. Greater weight bias was associated with greater depression, poorer body image, and increased binge eating. Despite significant reductions in negative internalized and explicit weight bias following treatment, weight bias remained strong. Conclusions Weight bias among treatment-seeking adults is associated with greater psychological maladjustment and may interfere with their ability to achieve optimal health and well-being.
