| Popis: | Purpose Assessment of executive functioning is an important element of a comprehensive assessment of intellectual abilities. Few assessments available are accessible for individuals with intellectual disabilities (ID) and none have population-specific norms. This paper aims to describe the adaptation of the behavioural assessment of dysexecutive syndrome (BADS). Design/methodology/approach Adaptations were made to the BADS tests to create the BADS – intellectual disabilities (BADS-ID). Data from three doctoral dissertations were combined to explore the utility, reliability, validity and component structure of the BADS-ID. Properties of the BADS-ID were compared with the Cambridge Executive Functioning Assessment (CEFA). Findings The BADS-ID is accessible to IQ range 50–70 and has a two-component structure. It has good inter-rater reliability, but poor internal consistency. It has a good face and content validity but evidence for concurrent and discriminative validity is weak. All properties are comparable to or better than the CEFA. Research limitations/implications Further research is needed to improve reliability and validity. The development of an accessible test battery with known reliability and validity for individuals with ID should facilitate research into executive functioning in this population. There is the potential to develop population-specific norms from the data. Practical implications An accessible test battery for individuals with ID is helpful in clinical situations. Originality/value To the best of the authors’ knowledge, this is the first study to explore the adaptation of the BADS for use with individuals with ID. |
