Adaptive functioning evaluations

In order to measure adoptive functioning, either the Independent Living Scales (ILS), or the Vineland Adaptive Behavior Scales Third Edition (Vineland-3) is used.

The ILS is an individually administered assessment of adults’ competence in instrumental activities of daily living. The instrument requires the examinee to do problem solving to demonstrate knowledge, or to perform a task. The individual’s performance can guide determination of the most appropriate living arrangement for adults who are cognitively impaired. Information at the item level is specific enough to identify needed support services, adaptation, or instruction for adults who are unable to function independently in certain areas of everyday living.

The Vineland-3 is a standardized measure of adaptive behavior that is used to measure the things that people do to function in their everyday lives. Vineland-3 is a norm-based instrument, thus, the examinee’s adaptive functioning is compared to that of other individuals of similar age. Vineland-3 was released in 2016 and is appropriate for individuals aged from birth to age 90. The scores are expressed as standard scores with a mean of 100, and standard deviation of 15. Vineland-3 addresses the domains of receptive, expressive, and written communication; personal, domestic, and community daily living skills; social skills of interpersonal relationships, play and leisure, and coping skills; fine and gross motor skills; and maladaptive behaviors.
