<p>Drawing on survey data collected in China—a prototypical particularistic society characterized by a strong distinction between familial members and extrafamilial partners—this article investigates how the patterning of specific trust in multiple referents relates to happiness among Chinese citizens. Ordinary least squares modeling and decomposition analyses yield four key findings. First, the trustworthiness of individual partners, whether familial or not, consistently shows a positive association with happiness. Second, the gap in mean trust scores between familial and extrafamilial trustees significantly and positively relates to happiness, net of the other covariates. Third, the relative heterogeneity of trust toward family members, compared to that toward nonfamily others, is associated with lower happiness when considered alone; yet this association ceases to be significant once mean differences in trust are taken into account. Fourth, decomposition analyses demonstrate that the familial–extrafamilial trust gap, net of relative trust heterogeneity, operates through variations in existential insecurity. This article illustrates that it is not only the trustworthiness of individual partners but also the pattern of trust across multiple partners that matters for subjective wellbeing.</p>
