However, few studies have examined the moderating effect of income sources on the relationship between living arrangements and PWB. Our aim was to examine whether living arrangements are associated with PWB and whether income sources moderate this association.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The data were drawn from the third (2002) to sixth (2011\/2012) waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Six questions reflecting older adults\u2019 well-being were used to measure PWB. Living arrangements were classified as follows: living alone, living with family and living in an institution. Income sources were categorized into financially independent, supported by children, and governmental support. We performed random-effects ordinal probit models to examine the association of living arrangements with PWB and the moderating effect of income sources on this relationship.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We included a total sample of 30,899 observations for 16,020 respondents aged 65 and over during 9-year follow-up.

Living in an institution with support from children (<jats:italic>\u03b2<\/jats:italic>= \u2212.22,<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05) led to lower PWB than living alone with financial self-support.
