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.
