Hypothesis
The study aims to evaluate the psychometric characteristics of the OPSAT-Q.
Conclusion
The OPSAT-Q is a valid and reliable measure for assessing patient satisfaction with bisphosphonate treatment in postmenopausal women.
Supporting Evidence
- The OPSAT-Q showed acceptable internal consistency reliability with Cronbach's alpha ranging from 0.72 to 0.89.
- Reproducibility for the OPSAT-Q was measured with an ICC of 0.81 for the composite score.
- Significant correlations were found between OPSAT-Q subscales and similar global measures.
Takeaway
This study created a questionnaire to help understand how satisfied women are with their osteoporosis treatment, and it showed that the questionnaire works well.
Methodology
Women with osteoporosis or osteopenia completed the OPSAT-Q and other questionnaires to evaluate satisfaction and psychometric properties.
Potential Biases
The sample was composed of volunteers, which may introduce selection bias.
Limitations
The focus groups were not representative of all women with osteoporosis, and small subgroup sizes limited some analyses.
Participant Demographics
Participants were primarily Caucasian women with a mean age of 65.1 years, most living with someone and not currently employed.
