Recent demographic shifts in the United States have substantially altered family structure. These shifts include an increase in the average life span, smaller family sizes, and changes in marriage patterns including individuals who never marry, divorce, remarry, and cohabitate (Silverstein & Giarruso, 2010; Wu, 2014). Taken together, these factors have resulted in increasingly complex family forms. These shifts in family structure have implications for family process including the quality of relationships across and within generations (Uhlenberg, 1996). Previous work has focused on examining relationship quality in the family of origin (e.g., parents and siblings). A potential consequence of focusing on families of origin is that researchers may overlook the role of other family systems including the extended family. Utilizing a population of 491 emerging adults (ages 18-25), I examined the association between characteristics of emerging adults (e.g., gender, closeness with family of origin, and romantic relationship status) and relationship quality (i.e., closeness and conflict) with extended family. I then evaluated how relationship quality (e.g., closeness and conflict) with extended family members is associated with emerging adults' well-being (i.e., selfacceptance and loneliness). In both papers, two measures for each relationship quality variable were created (average closeness, highest closeness, average conflict, highest conflict). Highest closeness and highest conflict were included to capture the extremes found within family relationships, and average closeness and average conflict were created to capture an overall assessment of relationship quality across all extended family members.
