The new Medical Expenditure Panel Survey-Primary Care (MEPS-PC) measure shows strong validity for assessing primary care processes. This tool aids researchers in understanding healthcare complexities and improving primary care research.
Area of Science:
- Health Services Research
- Epidemiology
- Biostatistics
Background:
- Primary care research needs validated measures for national datasets.
- Existing measures may not fully capture primary care processes.
Purpose of the Study:
- To assess the validity and reliability of the newly developed Medical Expenditure Panel Survey-Primary Care (MEPS-PC) measure.
- To provide evidence for the utility of MEPS-PC in primary care research.
Main Methods:
- Retrospective cohort study using 2013-2014 MEPS data.
- Tested construct validity of MEPS-PC subscales against established primary care measures.
- Used logistic regression for concurrent and predictive validity analyses.
Main Results:
- MEPS-PC subscales demonstrated strong concurrent and predictive validity, with 91-92% of estimates aligning with hypotheses and being statistically significant.
- Relationship and Health Promotion subscales showed uniform conformity.
- Comprehensiveness subscale showed significant results in 60% of bivariate odds ratio estimates.
Conclusions:
- The MEPS-PC composite measures provide preliminary evidence of concurrent and predictive validity.
- MEPS-PC is a potentially valuable tool for researchers studying primary care processes and healthcare complexities.
