Adaptive behaviour was formally incorporated into the diagnosis in 1959; the rationale being that IQ and adaptive behaviour were different constructs that independently contribute to the diagnosis. However, there are limited data on the relationship between IQ and adaptive behaviour and especially so for adults who have ID. The aim of this study was to investigate this relationship on two widely used assessment tools: the Wechsler Adult Intelligence Scale \u2013 fourth edition (WAIS\u2010IV) and the Vineland Adaptive Behaviour Scales (VABS).<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>Data were extracted from the case files of 147 adults who had a formal diagnosis of ID based on the WAIS\u2010IV and VABS. Internal consistency was computed and compared to general population data. Correlations between the WAIS\u2010IV and the VABS were computed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Internal consistencies for the tests when used with adults who have ID were generally good. The correlations between the WAIS\u2010IV and VABS composite and subdomain scores were all low and similar to those reported for the general population.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>These results suggest that the WAIS\u2010IV and VABS are measuring different constructs that contribute to the diagnosis of ID. Unfortunately, by the time such data have been collected, tests are being revised. The Vineland has now been revised and is in its third edition, but no data on the relationship between IQ and the VABS were collected during test development. The WAIS\u2010V is now in development, and so it is recommended that such work be incorporated into this process or shortly thereafter to ensure that the tools continue to access independent constructs.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jir.12610","type":"journal-article","created":{"date-parts":[[2019,2,20]],"date-time":"2019-02-20T05:29:35Z","timestamp":1550640575000},"page":"1158-1162","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Relationship between the Vineland Adaptive Behaviour Scales and the Wechsler Adult Intelligence Scale IV in adults with intellectual disabilities"],"prefix":"10.1111","volume":"63","author":[{"given":"M.","family":"Saleem","sequence":"first","affiliation":[{"name":"Clinical Psychology Unit, Department of Psychology University of Sheffield  Sheffield UK"},{"name":"Adult Learning Disability Specialist Health Service South West Yorkshire Partnership NHS Foundation Trust  Barnsley UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7916-9313","authenticated-orcid":false,"given":"N.","family":"Beail","sequence":"additional","affiliation":[{"name":"Clinical Psychology Unit, Department of Psychology University of Sheffield  Sheffield UK"},{"name":"Adult Learning Disability Specialist Health Service South West Yorkshire Partnership NHS Foundation Trust  Barnsley UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Roache","sequence":"additional","affiliation":[{"name":"Clinical Psychology Unit, Department of Psychology University of Sheffield  Sheffield UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,2,19]]},"reference":[{"key":"e_1_2_7_2_1","volume-title":"Mental Retardation: Diagnosis, Classification and Systems of Supports","author":"American Association on Mental Retardation","year":"2002"},{"key":"e_1_2_7_3_1","volume-title":"Intellectual Disability: Diagnosis, Classification and Systems of Supports","author":"American Association on Intellectual and Developmental Disabilities","year":"2010"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425596"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1352\/0047-6765(2003)41<286:UOTVAB>2.0.CO;2"},{"key":"e_1_2_7_6_1","volume-title":"Guidance on the Assessment and Diagnosis of Intellectual Disabilities in Adulthood","author":"British Psychological Society","year":"2015"},{"key":"e_1_2_7_7_1","volume-title":"SPSS for Windows Step by Step.
