The Relationship Code is the report of a longitudinal study, conducted over a ten-year period, of the influence of family relationships and genetic factors on competence and psychopathology in adolescent development. The sample for this landmark study included 720 pairs of same-sex adolescent siblings—including twins, half siblings, and genetically unrelated siblings—and their parents.Using a clear expressive style, David Reiss and his coinvestigators identify specific mechanisms that link genetic factors and the social environment in psychological development. They propose a striking hypothesis: family relationships are crucial to the expression of genetic influences on a broad array of complex behaviors in adolescents. Moreover, this role of family relationships may be very specific: some genetic factors are linked to mother–child relationships, others to father–child relations, some to relationship warmth, while others are linked to relationship conflict or control. The specificity of these links suggests that family relationships may constitute a code for translating genetic influences into the ontogeny of behaviors, a code every bit as important for behavior as DNA-RNA.

Intriguing new findings on how genes and environments work together through different stages of life take the spotlight in this significant collection. Studies from infancy to late adulthood show both forces as shaping individuals' relationships within family and non-family contexts, and examine how these relationships, in turn, continue to shape the individual. Transitional periods, in which individuals become more autonomous and relationships and personal identities become more complicated, receive special emphasis. In addition, chapters shed light on the extent to which the quantity and quality of genetic and environmental influence may shift across and even within life stages.Included in the coverage:Gene-environment interplay in parenting young children.The sibling relationship as a source of shared environment.Gene-environment transactions in childhood and adolescent problematic peer relationships.Toward a developmentally sensitive and genetically informed perspective on popularity.Spouse, parent, and co-worker: roles and relationships in adulthood.The family system as a unit of clinical care: the role of genetic systems.Behavioral geneticists, clinical psychologists, and family therapists will find in Gene-Environment Interplay in Interpersonal Relationships across the Lifespan a window into current thinking on the subject, new perspectives for understanding clients and cases, and ideas for further study.
