Summary
The Behavioural Assessment Scale (BAS) provides normative data for assessing adaptive functioning in older adults with severe cognitive impairment. This scale helps evaluate daily living, communication, social skills, and problem behaviors.
Area of Science:
- Gerontology
- Neuropsychology
- Behavioral Science
Background:
- The Behavioural Assessment Scale (BAS) was designed to evaluate adaptive functioning in elderly individuals experiencing severe cognitive impairment.
- Prior studies confirmed that BAS items can be analyzed as three distinct subscales: Daily Living Skills, Communication and Social Skills, and Problem Behavior, or as a comprehensive global functioning score.
Purpose of the Study:
- To provide regression-predicted, age- and mental-status-corrected percentile ranks for the BAS.
- To offer normative data specifically for a sample of severely cognitively impaired older adults, addressing the limited variability in unimpaired populations.
Main Methods:
- Utilized regression analysis to predict percentile ranks for BAS subscales and the total score.
- Collected data from a sample of older persons with severe cognitive impairment to establish normative values.
Main Results:
- Presented normative percentile ranks for the four BAS subscales (Daily Living Skills, Communication and Social Skills, Problem Behavior, and global functioning).
- Age- and mental-status-corrected scores were calculated to enhance the utility of the normative data.
Conclusions:
- The generated normative data for the BAS is valuable for clinicians and researchers working with older adults with severe cognitive impairment.
- The study provides essential psychometric information to support the accurate assessment of adaptive functioning in this specific population.
