If the results of the online questionnaire indicates that the child/young person or adult may have an intellectual disability and you have concerns about him/her, you may wish to contact your local services (for example, GP, paediatrician or intellectual disability service) to ask for advice. You can also visit the British Psychological Society website, which provides information about chartered applied psychologists in your local area in the UK who may be able to provide a private assessment of the person:

The CAIDS-Q and LDSQ have high levels of accuracy, however, they are less accurate under the following circumstances:

  • If the child is aged under 8 or if the young person is aged between 16 and 18 years.
  • If the person has an existing condition that may impact on the results of the screening questionnaire, such as a physical disability, specific learning difficulties, or Autism Spectrum Disorder.
  • If the person has English as a second language
  • If you had to guess the answers to any of the questions
