title: Estimating the severity of intellectual disability in adults: a Mokken scaling analysis of the Learning Disability Screening Questionnaire.
abstract: A Mokken scaling analysis of the learning disability screening questionnaire (LDSQ) suggested that, with the exception of 1 item, the scale conforms to the properties of a Mokken scale. This has advantages for estimating the severity of intellectual disability and inferring the difficulties likely to be experienced by an individual for whom there is incomplete information on intellectual and adaptive functioning.
