Purpose: When a mother is diagnosed with breast cancer, it affects the well-being of the entire family. Adolescence is defined by identity formation and a need to belong. A mother’s diagnosis can leave adolescents vulnerable to emotional isolation and unmet informational needs. Despite being deeply affected, their psychological strains often remain underestimated by their parents. Simultaneously, parents feel insecure about how to involve and inform their adolescents. To address this, two interventions involving a Family Information Group Meeting (FIGM) and a Support Group (SG) were developed, tested, and evaluated. This study examines how adolescents and their parents experienced and valued the interventions. Sample and Setting: Seven parents were interviewed after participating in the FIGM. Five adolescents were interviewed after participating in the FIGM and SG. All interviews were conducted in rooms at the Danish Cancer Society’s counselling house. Procedure: Six semi-structured interviews were conducted with parents individually or in couples. A three-hour focus group was conducted with participating adolescents. Evaluation questionnaires were completed by 31 participants in the FIGM. Reflexive thematic analysis was conducted, enabling an interpretative exploration of participants’ perspectives. The analysis was informed by Park’s Meaning-Making Model, providing a theoretical framework for understanding how participants experienced the interventions. Preliminary findings: Parents and adolescents described the SG and the FIGM as supportive, especially due to the shared context between participants and the peer exchanges - resulting in a sense of belonging. Participants greatly valued knowing that others shared similar feelings in a comparable situation. Conclusion: These interventions address a gap in psycho-oncological care targeting parents and adolescents affected by maternal breast cancer. By reducing isolation and enhancing family communication, the interventions respond to core challenges faced during mothers’ breast cancer trajectories.
