Cross-cultural adaptation of the web-based executive functioning questionnaire for Brazilian sample (Webexec-BR)

Area of Science:

• Psychology
• Neuroscience
• Psychometrics

Background:

• The Web-based Executive Functioning Questionnaire (Webexec) is a brief online tool for assessing executive functions.
• Cross-cultural adaptation of psychometric instruments is crucial for broader applicability.
• Previous adaptations of Webexec to diverse cultural contexts remain limited.

Purpose of the Study:

• To perform a cross-cultural adaptation of the Webexec for a Brazilian sample.
• To evaluate the psychometric properties of the adapted Webexec in Brazil.
• To establish the validity and reliability of the Brazilian version of Webexec.

Main Methods:

• A longitudinal study design was employed with 295 Brazilian participants (mean age 20.69).
• The Webexec was administered, with a reapplication six weeks later to assess reliability.
• Both classical and contemporary psychometric methods were utilized for data analysis.

Main Results:

• The Brazilian version of Webexec exhibited excellent psychometric properties.
• Evidence of validity was found based on content and internal structure.
• High reliability and precision were confirmed for the adapted scale.

Conclusions:

• The adapted Webexec is a psychometrically sound instrument for assessing executive functions in Brazil.
• Further research with larger and diverse Brazilian populations is recommended.
• The study supports the use of Webexec in cross-cultural research on executive functions.
