Abstract Background Treatment options for weight loss vary considerably with regard to risks and benefits, but the relative importance of treatment characteristics in patient decision-making is largely unknown, particularly amongst patients with severe obesity. Developing such services requires insight into the preferences of recipients for service attributes. Objective The objective of this study was to quantify, using a discrete choice experiment, the preferences of treatmentseeking patients with severe obesity within the Irish population regarding different attributes of various obesity treatments. Methods Within a cohort of patients with severe obesity attending a hospital-based weight management programme, patients’ attitudes to and perceptions of three distinct treatment modalities were compared to those regarding not having treatment. The treatments included a structured lifestyle modification programme, lifestyle modification alongside weight loss medication, and bariatric surgery. Results On average, patients with severe and complicated obesity who were attending a weight management programme were more enthusiastic about participating in a programme to help improve their diet and physical activity than they were about having surgery if the methods of treatment had equivalent results and costs. Conclusion The findings provide insights into preferences that might assist the development of more appropriate treatments for severe obesity.
Key Points for Decision Makers Adopting a singular therapeutic approach for individuals with severe obesity will not suffice.

We estimated the overall mean willingness to pay for lifestyle modification to be significantly higher than that for bariatric surgery, other things being equal.

1 Introduction
Francis Finucane [email protected]
While the global prevalence of obesity is increasing [1], the rise in the number of patients with severe obesity (body mass index [BMI] > 40 kg/m2) has been particularly dramatic [2]. Individuals who are severely obese have on average much more complex health issues and encounter very different challenges in the healthcare system than the majority of moderately obese individuals (BMI ≥ 30–35) [2].
