  1. Child and Adolescent Intellectual Disability Screening Questionnaire (CAIDS-Q)McKenzie & Paxton Dr Karen McKenzie

  2. Contents • Why to we need a screening tool for adolescents with a learning disability? • What makes a good screening tool? • Description of the CAIDS-Q • Uses of the CAIDS-Q? • Developing the CAIDS-Q: Validity and reliability • Contact details

  3. Why is there a need for a screening tool? • Policy recommendations have led to a demand on services to identify young people with an intellectual disability as early as possible e.g. in forensic settings • Full diagnostic assessments are expensive, time-consuming and need to be carried out by properly qualified, applied psychologist • Cost to individual and society if adequate support is not given

  4. What makes a good screening tool? • Cost effective • Quick and simple to administer and score • Requires minimal training • Valid i.e. Measures what it sets out to measure • Reliable i.e. Gives consistent results across time and different users

  5. Description of the CAIDS-Q • Has 7 items • Can be completed with/by the individual or by someone who knows him/her well • Takes 5-15 minutes to complete • Can be sent to referrers to complete • Easy to score • No training required • Covers age range 8-18 years

  6. Uses The CAIDS-Q can potentially help to: • Quickly identify appropriate services for an individual • Avoid a long wait for initial assessment • Allow resources to be targeted at those who need them most • Identify people who may be vulnerable e.g. within criminal justice system • Provide a means for discriminating between groups for research purposes • Help GPs identify those with an intellectual disability within their practice

  7. Developing the Questionnaire • Literature search for existing tools • Selecting the questions • Standardisation,Validity & Reliability • Easy to use • Research base

  8. Standardisation • Developed to distinguish between those people who are typically referred to intellectual disability and child and adolescent mental health services • Also included a forensic sample

  9. Validity • The CAIDS-Q score correlated significantly with WISC IV scores • The CAIDS-Q scores could discriminate between those with an intellectual disability and those without • A ROC analysis showed the CAIDS-Q could identify people with an intellectual disability with 97% accuracy and those without with 86% to 87% accuracy (depending on the age of the individual) • Small forensic sample (n=23) found CAIDS-Q correctly identified all those with and without an intellectual disability.

  10. Reliability Inter-rater reliability was significant for each item on the questionnaire. (It was excellent for all 7 items)
