Validation of Two Quality of Care Measures: Results from a Longitudinal Study of Reversible Contraceptive Users in India.

Abstract

Bruce's quality of care framework, developed nearly three decades ago, brought needed international attention to family planning services. Various data collection efforts exist to measure the quality of contraceptive services. Our study validates two process quality measures and tests their predictive validity related to contraceptive continuation among 2,699 married women who started to use a reversible contraceptive method in India. We assessed four process quality domains with 22 items, which were reduced to 10 items using exploratory factor analysis. Weighted additive indices were calculated for the 22- and 10-item measures. Scores were trichotomized into high, medium, and low process quality received. The predictive validity of the two measures was assessed related to modern contraceptive continuation three months later. The adjusted odds of continuing a modern contraceptive three months later was nearly three times greater (AOR: 2.78; 95% CI: 1.83-4.03) for women who received high process quality at enrollment compared with low quality with the 22-item measure, and 2.2 times greater (95% CI: 1.46-3.26) with the 10-item measure. Results suggest that the 22- and 10-item measures are valid, and while the larger 22-item measure can be used in special studies, the 10-item measure is more suited for routine data collection and monitoring.
