Clinical depression and overweight or obesity (OW/OB) frequently co-occur. Either condition significantly increases risk of developing the other whilst being obese significantly reduces utilisation of psychotherapy. To date, the few interventions developed to treat clinical depression in adults with co-morbid OW/OB have combined standard interventions aimed at reducing depression or promoting weight loss from a conceptual framework based on depression and obesity as discrete conditions. The overall aim of the present research is to develop an integrated evidence-based program for clinical depression involving psychotherapy and regular exercise for adults with co-morbid OW/OB. We conducted a meta-analytic review investigating current treatments for symptoms of depression in adults with OW/OB. We compared three different exercise-based interventions among 36 adults with clinical depression and OW/OB in a randomised controlled clinical trial (RCT). To further understand the contributing factors influencing depression and treatment gains in this population, we conducted mixed methods research with a subgroup of participants who completed the RCT, including thematic analysis of 17 interviews. The findings from this research were then incorporated into a protocol paper for an RCT which will assess the impact of a tailored, evidence-based approach to treating clinical depression in overweight or obese adults. This novel approach combines elements of cognitive behaviour therapy, including schema, self-compassion and mindfulness-based approaches along with an evidence-based exercise program for depression.
