ongoing projects

 
  1. "Understanding and measuring risk attitudes in Singapore" Understanding how people respond to uncertainty and risk as well as the causes and consequences of their responses is essential for managing and coping with uncertainty and risk, both individually and collectively. This project aims to understand risk attitudes across life domains among Singaporeans, and to develop a measurement tool of assessing risk attitudes for Singaporeans. This project will also investigate how risk attitudes relate to behaviours and mental health among Singaporeans.
  2. "Understanding health and medical decisions under uncertainty" Health and medical decision under uncertainty can be complex in real life. This project aims to systematically investigate the risk and benefit considerations and priorities in medical and health decisions. It also explores how risks and benefits of medical and health decisions can be best communicated. This project will provide a novel framework to understand the nature of decision-making in laypeople’s everyday health and medical settings.
  3. "Improving informed consent in clinical trial participation in Southeast Asia" What are the barriers of informed consent in Singapore, as well as other countries in Southeast Asia? What can we do to ease the burden of everyone in this process? This project aims to unpack these important issues by understanding perspectives from regulators, researchers, clinicians, and patients. Through the in-depth understanding of the experiences and challenges in informed consent faced by different groups, we aim to gain insights on the solutions to improve informed consent in the region.
  4. "Improving consent and decision-making in time-sensitive healthcare settings" Communicating risk in urgent medical situations is challenging and informed decisions can be difficult under time pressure. This project aims to understand Singaporeans’ experiences of decision-making and consent in time-sensitive medical settings. This project aims to bridge gaps between patients, healthcare providers, researchers, and regulators to promote effective risk communication in time-sensitive healthcare settings
  5. "Promoting risk communication and community engagement in clinical and public health research" The public’s trust and engagement in clinical research is essential for reducing costs of clinical research as well as improving short-term and long-term public health outcomes. We aim aims to identify and address the “perception gaps” between clinicians/researchers and the public, and to promote the public’s engagement are critical to improve communication in clinical settings and to facilitate recruitment in clinical research.
  6. "Risk propensity and substance use" Substance use and disorders pose significant global public health challenges, leading to considerable health burdens and societal consequences. Risk propensity has been identified as a critical factor influencing substance use behaviours. This meta-analysis aims to evaluate the associations between risk propensity and substance use as well as disorders using a meta-analysis. Additionally, it aims to investigate potential factors that can alter the associations to further examine potential mechanisms underlying the link between risk propensity and substance use.
  7. "World Risk Poll and Mental Health Services" Quality mental health services are pivotal in addressing mental health issues worldwide. Despite this importance, many countries face challenges in providing accessible, high-quality mental health care. This project aims to analyse the Lloyd's Register Foundation World Risk Poll 2021, and data sourced from databases such as WHO and OECD to understand the relationship between mental health services and the public's worry about mental health issues.
