Background: Inherited risk is a family issue. Identifying family members who carry a pathogenic genetic variant that increases risk of cancers and other chronic diseases can be lifesaving for those affected.Objective: The research questions are: (1) which family communication frameworks have been applied, (2) how do intervention strategies employed map to these theories, and (3) to what extent were families receptive to these strategies and communication increased?Methods: Manuscripts published between January 2010 and August 2020 were searched in three databases: PubMed, PsycINFO, and Web of Science.Results: Nine intervention trials were identified. All interventions were evaluated in clinical genetic counseling contexts using at least one individual-level strategy (e.g. increase knowledge). Only three focused on dyadic conversations such as preparing for relatives' information needs.Conclusions: This systematic review posed the question whether theoretically based approaches have been applied to foster family genetic risk communication. Greater attention needs to be paid to the utilization of dyadic level and family system level theories to guide intervention developments.Practical Implications: We conclude by calling for accelerating and broadening the development of interventions to enable family communication about inherited risk that are theory-based, incorporate family-systems thinking, and are conducted outside of specialty clinic settings.

Effective communication of cancer-related genetic and genomic testing (CGT) with patients and the public is paramount to transforming and managing cancer prevention, detection, and care. Behavioral and social science theories could improve communication effectiveness and, in turn, health outcomes. In this study, we characterized the use of theory in recent research on communication about CGT from 2010 to 2017. Of 513 empirical papers focusing on communication about CGT, only 119 (23%) utilized any theory in the study design. Behavior change and health psychology/cognitive representation theories (24.2% and 21.9%, respectively) were the most commonly used with minimal use of communication theories (3%). Theories were primarily used to guide hypotheses or research question development (73.9%), and for selecting measures or codes (68.9%). Approximately half of the papers (48.3%) related their study findings to the referenced theory. Fewer papers (14.3%) discussed implications of the findings for the theory. While theories are being utilized to inform study design, few discuss their results in the context of theoretical implications and thus decrease potential generalizability. Greater use of theory could help scholars to identify and develop theories suited to this clinical context and inform our understanding of related communication processes more broadly. • Atheoretical approaches are more prominent in communication of CGT scholarship. • These approaches limit evidence-based policy, research foci, standards of care. • Theory-driven studies use theory for RQ development and measure selection. • Majority of studies did not discuss their results to cited theory nor implications. • More theory-driven studies are needed to enhance generalizability of findings.
