Background: The decision to initiate medication is complex and is influenced by a variety of factors. There is limited information on the relative importance of factors that influence the initiation of ADHD medication.
Aims: To investigate the factors, and their relative importance, that influence the decision to initiate medication in adults, and parents of children, with ADHD.
Methods: A discrete choice experiment was conducted using eight choice tasks made up of five attributes that described the outcomes of initiating medication. A mixed multinomial logit model was used to estimate preferences for medication.
Results: Respondents' overall preferences for initiating medication were negative (Mean (β)= -0.72705, < 0.1), however, significant heterogeneity was noted in preferences (SD: 0.93604, < 0.001). Side-effects were the most important factor for both adults (Relative importance (RI) = 40.39%) and parents (RI = 41.99%). Improvement in education had a greater weighting in adults' decision-making compared to parents (RI = 36.93% vs 30.47%) while improvement in aggressive (RI = 14.38% vs 11.84%) and social behaviour (RI = 12.59% vs 10.37%) was more important to parents.
Conclusions: Important differences in preferences of patients and parents were identified, highlighting that the decision to initiate medication is influenced differently in different individuals and groups.

Which antidiabetic drugs do patients of T2DM prefer in India and why? A discrete choice experiment.
J Family Med Prim Care
November 2024
Department of General Medicine, All India Institute of Medical Sciences (AIIMS), Bhopal, Madhya Pradesh, India.
Background: Uncontrolled diabetes persists despite guideline-based treatment, partly attributed to inadequate patient involvement. This research addresses shared decision-making by eliciting patient preferences in Type 2 Diabetes Mellitus (T2DM) treatment based on certain key attributes and explores their correlation with socio-demographic-clinical profiles.
Methods: A discrete choice experiment (DCE) was conducted among T2DM outpatients in an Indian tertiary care center.
Background: Prior to COVID-19, little was known about how risks associated with such a pandemic would compete with and influence patient decision making regarding cancer risk reducing medical decision making. We investigated how the pandemic affected preferences for medical risk-reducing strategies among women at elevated risk of breast or ovarian cancer.
Methods: We conducted a discrete choice experiment.

Objective: To develop a value set for the Short-Form 6-Dimension version 2 (SF-6Dv2) by incorporating societal preferences obtained from three distinct approaches: Standard Gamble (SG), composite Time Trade-Off (cTTO), and Discrete Choice Experiment (DCE).
Methods: Data were gathered from the general population of Quebec, Canada, using the standardized valuation protocol developed by EuroQol for the cTTO and DCE tasks, as well as the valuation protocol developed by Sheffield University for the SG. The SG and cTTO data were analyzed using OLS, GLS, GLS Tobit, and heteroskedastic Tobit models.
Optimisation of services to prevent dental caries for school-aged children in China: a discrete choice experiment.

Stomatologic Hospital & College, Key Lab of Oral Diseases Research of Anhui Province, Anhui Medical University, Hefei, Anhui, China
Objectives: The objective of this study is to analyse the preferences of guardians of school-aged children for children's caries prevention services (CPS) and their willingness to pay (WTP) for different levels of attributes.
Design: Four key attributes were identified through a literature review and expert consultations: preventive service time, preventive effectiveness, distance (driving time to service institution) and service cost (out-of-pocket for CPS). A D-efficient design was used to create a discrete choice experiment questionnaire, and data were collected via face-to-face interviews.
Medically assisted integrated rehabilitation program for people with opioid dependence: a quasi-experimental evaluation using multi-criteria decision analysis.
BMC Psychiatry
December 2024
Department of Economics, University of Bergen, Postboks, Bergen, 7802, 5020, Norway.
Background: Opioid use disorders constitute a vast disease burden, need for comprehensive treatment, and substantial costs to individuals, families, and society. The multifaceted needs of people with opioid dependence call for integrated care. The study aims to assess the added value of an integrated medically assisted rehabilitation (MAR) program providing opioid agonist therapy for patients with opioid dependence as compared to the standard of care (SoC) in Norway.
