Background: Reliable and valid screening instruments for depression and anxiety are needed for adults with intellectual disabilities. Methods: Internal consistency (n = 198), inter-rater reliability (n = 41), test-retest reliability (n = 37) and criterion validity (n = 43) were studied in adults aged between 18 and 49 years. Internal consistency…

Background: Adaptive skills measures tend to be lengthy. The GO4KIDDS (Great Outcomes for Kids Impacted by Severe Developmental Disabilities; (Journal of Applied Research in Intellectual Disabilities, 58, 2015 and 594)) Brief Adaptive Behaviour Scale was developed to provide a brief assessment of adaptive skills. Our study aimed to examine the…

The prevalence of mild or borderline intellectual disabilities (MBID); an umbrella term for people with borderline intellectual functioning (BIF) and mild intellectual…

Background: The Learning Disability Screening Questionnaire (LDSQ) has been shown to have high sensitivity and specificity to identify those who are likely to meet intellectual disability diagnostic criteria (McKenzie, et al. [McKenzie K., 2015]). However, there is no independent research to date to support these findings. Materials and Methods:…
