Summary
The Dental Attitude Questionnaire (DAQ) factor structure differs between the original and Dutch versions. A confirmatory factor analysis revealed a two-factor solution, not the original three-factor structure, impacting oral health attitude assessment.
Area of Science:
- Oral health psychology
- Dental attitude assessment
- Psychometric validation
Background:
- The Dental Attitude Questionnaire (DAQ) was developed in 1984 to measure attitudes toward oral health care.
- It comprises six content scales (Cynicism, Health Concern, Motivation, Oral Function, Social Aesthetic, Susceptibility) and two validity scales (Halo, Infrequency).
- A Dutch translation of the DAQ was published in 1986.
Purpose of the Study:
- To replicate the original factor analysis of the Dental Attitude Questionnaire (DAQ).
- To investigate the factor structure of the Dutch translation of the DAQ.
- To compare the factor structure of the original DAQ with its Dutch translated version.
Main Methods:
- Replication of the factor analysis performed by STOCKWELL & BANTING on the original DAQ.
- Administration of the Dutch translated DAQ to a study sample.
- Confirmatory factor analysis to assess the fit of the original three-factor structure to the translated data.
Main Results:
- The factor analysis of the Dutch DAQ resulted in a two-factor solution, deviating from the original three-factor structure.
- Confirmatory factor analysis indicated that the original three-factor structure of the DAQ is not supported by the data from the translated version.
- A significant change in the factor structure was observed between the original and translated versions of the DAQ.
Conclusions:
- The factor structure of the Dental Attitude Questionnaire (DAQ) is not invariant across different language versions.
- The Dutch translation of the DAQ exhibits a different factor structure compared to the original English version.
- Further research is needed to understand the reasons for the observed changes in the DAQ's factor structure and their implications for oral health attitude assessment.
