A separate social language barrier was constructed from linguistic distance to the local dialect using hierarchical dialect classifications. This design allowed researchers to examine whether distance from the standard language and distance from the dialect spoken in the destination community had different statistical relationships with public health services. Two outcomes were analyzed: establishing a health record, a formal administrative service, and receiving health education, a community-based interactive service.

The researchers fitted Probit regression models that included comprehensive covariates as well as city-level and industry fixed effects. They reported average marginal estimates to support comparisons between the model estimates. Both the institutional and social language barriers were significantly associated with a lower probability of establishing a health record.

For health education, however, the association was concentrated mainly in the social language barrier, indicating that the two outcomes did not have the same pattern of language-distance correlates. Interaction analyses showed that the institutional and social barriers operated as parallel, independent constraints rather than compounding one another. The additional linguistic distance from a local dialect was not associated with a stronger institutional barrier, and the institutional measure did not appear to amplify the social barrier.

Moderation analysis also found that higher educational attainment helped buffer the negative associations linked with severe structural dialect distances. These results support treating the measures as distinct constraints associated with different services, although the observational design does not establish that language distance caused the differences in uptake. The evidence is also limited to two service outcomes, survey data collected in 2017 and migrants from regions where Standard Mandarin was not native.

The findings therefore describe associations within that population and setting rather than measured effects on health outcomes, service quality or long-term health.
