Key Strands of our Research

  • Development and evaluation of psychological therapies for behaviour problems, mental health issues or difficulties at a family/wider system level
  • Evaluation of health service provision for individuals with intellectual disabilities
  • Ageing: health issues associated with ageing in persons with intellectual disabilities
  • Stigma: Promotion of well-being and evidence based approaches to reducing the stigma associated with intellectual disability in the context of a multicultural society


The following are some of the current key research projects undertaken by CIDDR. Details of all student projects can be found on the CIDDR team page.

Stigma associated with intellectual disability

We are currently carrying out several studies related to stigma:

1.  Lay responses to people with intellectual disabilities and efforts to tackle stigma associated with intellectual disability in the context of ethnically and religiously diverse societies

Lay people often find the concept of intellectual disability and the different terminologies used confusing. Where lay people show negative emotional responses, hold stigmatising beliefs and attitudes this can have a very negative effect on the lives of persons with intellectual disabilities and their families and carers. We are completing several studies to understand more about lay responses in different cultural and religious communities. We are also currently piloting a range of interventions aimed at reducing negative attitudes and stigmatising beliefs among children and adults in the general population.

3. International Scoping Review of Efforts to Raise Awareness and  Combat Prejudice and Discrimination directed at people with ID

This scoping review aims to collect both empirical and anecdotal evidence from around the globe relating to responses to people with intellectual disabilities at community/societal level. The project engages with researchers, statutory and 3rd sector organisations, self-advocates, family members of people with intellectual disabilities, and campaigning bodies around the world.Our central aim is to identify what is happening to raise awareness and combat prejudices and discrimination, in line with Articles 5 and 8 of the UN convention of the Rights of People with Disabilities (CRPD).
