Dementia Questionnaire for People with Learning Disabilities (DLD) - Additional Research Using DLD

Other studies using the DLD are mentioned in the manual:

Burt et al (1999) in the US, specifically evaluating assessment of orientation in 138 adults aged 29-82 years, found fair to good agreement between DLD scores on the subscale ‘Orientation’ (single ratings) and direct assessment. The level of agreement was negatively influenced by lower functioning, Down’s syndrome and higher age.

Deb & Braganza (1999) in the UK compared ratings on several informant-based scales with the clinician’s diagnosis (ICD-10) among 62 adults with Down’s syndrome.

Silverman et al (2004) performed a study of dementia in 273 adults with learning disabilities, applying multiple tests 18 months apart.

Shultz et al (2004) in the US and Canada evaluated several screening tools for dementia in a case-control study, with 38 matched participants with mild to profound learning disabilities in each group.
