A lack of understanding of the solidarity principle is one of the main reasons for low population coverage in microhealth insurance schemes. This study aimed to examine the extent to which people value solidarity and the factors that explain the differences.</p><p><strong>Methods: </strong>A community-based cross-sectional study was carried out in two districts of northeast Ethiopia among 1232 randomly selected households which have ever been registered in a community-based health insurance scheme. Face-to-face interviews were conducted with household heads using a standardized questionnaire deployed to an electronic data collection platform. Solidarity was measured using three dimensions: income solidarity, risk solidarity, and cost coverage. Principal component analysis was used to construct composite variables, and the reliability of the tools was checked using Cronbach's alpha. A multivariable analysis was performed using the partial proportional odds model to determine the associations between variables. The degree of association was assessed using the odds ratio, and statistical significance was determined at 95% confidence interval.</p><p><strong>Results: </strong>Three-quarters (75%) of the respondents rated risk solidarity as high, while 70% and 63% rated income solidarity and cost coverage as high, respectively.

In the first stage, this study employs a slacks-based measure and the data envelopment analysis-window analysis approach to conduct individual (economy and transportation) and joint assessments to measure health efficiency.
