Relationship avoidance and anxiety scores were obtained for 590 American young adults (M age = 23.1 yr.). Canonical correlation yielded two orthogonal patterns between the avoidance and anxiety scores with individual, demographic, and family variables. Relationship avoidance was most parsimoniously related to unresolved issues with one's family of origin, having been sexually abused, and being male (canonical correlation = .33). Relationship anxiety was most parsimoniously related to unresolved issues with one's family of origin, lack of personal income, having a strong libido, being young, and being female (canonical correlation = .25). Relationship avoidance was also correlated with not having affectionate and available parents, not having a secure and loving family, high parental conflict, low parental education and income, not having grown up with both parents, family violence, and low libido. Relationship anxiety was also correlated with low personal education. Marital status, ethnicity, and religious denomination were unrelated to either construct.
