Summary
A German version of Broadbent's Cognitive Failures Questionnaire was created to measure everyday errors. While correlations with anxiety and coping were significant, further research is needed on its overall score utility.
Area of Science:
- Psychology
- Cognitive Psychology
Background:
- No comparable German instrument existed for Broadbent's Cognitive Failures Questionnaire.
- Assessing cognitive failures in everyday situations is crucial for understanding daily functioning.
Purpose of the Study:
- To develop and validate a German version of the Cognitive Failures Questionnaire (CFQ).
- To assess the external and construct validity of the German CFQ.
Main Methods:
- Translation and adaptation of the original Cognitive Failures Questionnaire into German.
- Correlational analyses with measures of trait anxiety, coping styles, and action control for construct validation.
- Maximum likelihood factor analysis to examine the questionnaire's structure.
Main Results:
- The German CFQ showed significant, though moderate, positive correlations with observable failures in everyday situations (external validity).
- Most correlations with trait anxiety, coping styles, and action control were significant and in the expected direction (construct validity).
- Factor analysis indicated potential issues with the utility of the total score, suggesting further investigation into unidimensionality is required.
Conclusions:
- The developed German CFQ is a potentially useful tool for assessing cognitive failures.
- The questionnaire demonstrates adequate external and construct validity.
- Further psychometric investigation is recommended to confirm the unidimensionality and refine the interpretation of the total score.
