This is a PhD paper that is nearly 500 pages long and not worth reading entirely at this stage in the process, but the abstract offers some insight and the table of contents helps with finding more relevant pieces. The author measures similar ideas but in Mexico and a more thoroughly pluralistic setting, and also uses a Pregnancy Related Anxiety scale I have not before seen.
“Linear regression models indicate that participants who are more consonant in the model have lower levels of both PSS and PRA. Consonance is not associated with EBV antibody levels. Perceiving social support from family and non-family enhances the effect of consonance on PRA, unless perceived family support is above the mean. In this case, the effect is blunted. Social support does not moderate the effect of cultural consonance on PSS.”
