The Vineland Adaptive Behavior Scale is a psychometric instrument used in child and adolescent psychiatry and clinical psychology.
In 2005, Vineland-II was published, which added a 4th domain of motor skills, and in 2016 Vineland-3 was published, where the overall number of items on the scale increased by 34%.
[3] The Vineland Adaptive Behavior Scale assesses a person's adaptive level of functioning by standardized interview of the person or their caregiver through their activities of daily living such as walking, talking, getting dressed, going to school, preparing a meal, etc.
The original Vineland interview assessed three domains: communication, socialization and daily living, which correspond to the 3 domains of adaptive functioning recognized by the American Association on Intellectual and Developmental Disabilities namely conceptual skills (language and literacy, mathematics, time and number concepts, and self-direction), social skills and practical skills of daily living.
[4] Since no gold standard for evaluation of adaptive behavior exists, the test validity of this tool is unknown.
