Summary
The Adaptive Behavior Assessment System (ABAS-3) was successfully adapted to Brazilian Portuguese, ensuring its validity for assessing adaptive skills across diverse cultural contexts.
Area of Science:
- Psychometrics
- Cross-cultural Psychology
- Developmental Psychology
Background:
- Adaptive behavior assessment is crucial for understanding individual development.
- Cross-cultural factors significantly influence adaptive behavior.
- Existing instruments require cultural validation for diverse populations.
Purpose of the Study:
- To describe the cross-cultural adaptation of the Adaptive Behavior Assessment System, third edition (ABAS-3), to Brazilian Portuguese.
- To ensure the instrument's conceptual, idiomatic, and semantic equivalence in the Brazilian context.
Main Methods:
- Translation and back-translation by independent experts.
- Synthesis of translations by a consensus panel.
- Expert review and content validity analysis by 33 health and education specialists.
- Evaluation of 1121 items across five ABAS-3 forms.
Main Results:
- 82 out of 1121 items (7.31%) required revision.
- High agreement among specialists was observed for most items.
- Good evidence of content validity and adaptation adequacy was established.
Conclusions:
- The cross-cultural adaptation of the ABAS-3 to Brazilian Portuguese was successful.
- The adapted instrument is suitable for assessing adaptive behavior in Brazil.
- This validated tool supports the evaluation of conceptual, social, and practical adaptive skills.

Behavioral approaches have often been criticized for ignoring mental processes and focusing solely on observable behavior. However, these approaches provide an optimistic perspective for individuals seeking to change their behaviors. Rather than concentrating on intrinsic personality traits, behavioral approaches suggest that even longstanding habits can be modified by changing the reward contingencies that maintain them.
