Do associations between sense of purpose, social support, and loneliness differ across the adult lifespan?

Past research has suggested that the path to purpose involves connections with people along the way. In support, sense of purpose appears higher amongst those adults with more positive social relationships and interactions. However, research has yet to consider whether associations between sense of purpose and social relationship variables differ across adulthood. The present study examined this claim using a sample of Swiss adults, who completed measures for sense of purpose, loneliness, received support, and provided support. A large, nationally representative sample of 2,312 Swiss adults (52.34 years old; = 17.35) completed these measures, as part of a larger survey. Local structural equation modeling was employed to estimate the means and associations of these constructs across adulthood. Sense of purpose was negatively associated with loneliness, but positively associated overall with both support variables. No evidence was found for age moderation for the association between sense of purpose and loneliness. However, moderation was evidenced insofar that sense of purpose was less associated with both support variables with age. Sense of purpose again appears related to more positive social well-being and relationships, and consistently linked to lower loneliness. The age moderation effects for purpose-support associations are discussed with respect to theories of adult development. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
