Psychosocial Intervention for Women With Mood Disorders Seeking Treatment for Obesity

Pilot feasibility trial to examine the acceptability and efficacy of compassion-based intervention in reducing indices of psychopathology (i.e., internalized weight stigma, mood symptoms), and improving weight management outcomes (i.e., physical activity behaviour, dieting behaviour, weight loss) among women with mood disorders undergoing lifestyle weight management. In this proof of concept study, adult females with a diagnosis of major depressive disorder of bipolar disorder will be randomized into two arms: weight management treatment as usual + psychoeducation group; weight management as usual + control.
