The Vineland® : II assesses personal and social skills needed for everyday living. It is also used to identify individuals who have an intellectual disability or other disorders such as Autism, Asperger Syndrome and developmental delays. Not only does Vineland aid in diagnosis, but it provides valuable information for developing educational and treatment plans. Vineland® : II's increased coverage of early childhood adaptive behaviour improves classification of moderate to profound intellectual and developmental disabilities. Furthermore, a more complete coverage of adult adaptive behaviour improves detection of decline in older adults.
