Multiple Raters & Different Perspectives

The ABAS-3(HK) includes two rating forms: Parent/Primary Caregiver Form (ages 4–6 years) & Teacher/Daycare Provider Form (ages 4–6 years). Parents, family members, teachers, daycare staff, supervisors, counselors, or others who are familiar with the daily activities of the individual being evaluated can complete these forms. The items may be read aloud to raters who have low sight or poor reading skills. Although it’s possible to evaluate adaptive skills using only a single rater, gathering ratings from several people will provide a more complete assessment. Multiple ratings show how the individual performs in various settings. When different forms are used by different raters to evaluate an individual’s adaptive skills, a comparative report can be generated to show areas that warrant further attention.

Updated and Improved Psychometric Properties

The normative sample was stratified to match current Hong Kong census data based on sex, parent education level, and geographical region for each group Improved subtest floors and ceilings Comparable or improved reliability for subtest and composite scores.

Localization adaptation

ABAS-3(HK) has made localized modifications to the presentation and context of some questions based on the local language usage and customs in Hong Kong, so that the test-takers can clearly understand the content of the questions and answer them fluently.

Use & Applications

The ABAS-3(HK) covers three broad adaptive domains: Conceptual, Social, and Practical. Within these domains, the ABAS-3 (HK) assesses 10 adaptive skill areas (each form assesses 9 or 10 skill areas based on raters range). Items focus on practical, everyday activities required to function, meet environmental demands, care for oneself, and interact with others effectively and independently. Raters use a four-point response scale to indicate whether the individual can perform each activity and, if so, how frequently the individual performs it when needed.
The ABAS-3 is aligned with the AAIDD, DSM-5, and IDEA specifications and works well within an RTI context. The ABAS-3 generates norm-referenced scaled scores and test-age equivalents for the 11 skill areas. It also provides standard scores, confidence intervals, and percentile ranks for the three broad adaptive domains and for the summary score—the General Adaptive Composite. Scores can also be categorized descriptively (Extremely Low, Low, Below Average, Average, Above Average, High).
