Hypothesis
This study evaluated the psychometric properties of a 14-item Computerized Lifestyle Assessment Scale (CLAS).
Conclusion
The CLAS is a promising approach for evaluating patients’ attitudes toward computer-based health-risk assessments.
Supporting Evidence
- The study achieved a response rate of 97.6% with 202 completed surveys.
- Principal component analysis revealed four subscales with good internal consistency.
- Test-retest reliability showed high stability over time with intraclass correlation coefficients.
Takeaway
The study created a questionnaire to understand how patients feel about using computers to check their health, and it found that the questionnaire works well.
Methodology
The study involved 202 female patients who completed a paper questionnaire and a follow-up assessment after two weeks.
Potential Biases
Participants were more educated than the general population, which may affect the findings.
Limitations
The study primarily involved female patients from a single site, which may limit generalizability.
Participant Demographics
Participants had a mean age of 45.3 years, with 36% being immigrants and 77% having at least a university education.
