Informal caregivers of older adults with chronic illness have unique barriers to social connection. As the older adult population increases, individualized interventions are urgently needed to address the social disconnection experienced across generations of informal caregivers. Adapting an evidenced-based intervention to target social connectedness and leverage technology-mediated communication may be a promising approach. This article describes the adaptation of the Brief Behavioral Activation Treatment for Depression-Revised intervention using elements of the Framework for Reporting Adaptations and Modifications-Enhanced. Facilitating the comprehensive documentation of modifications made, we discuss the (a) rationale for modifications, (b) timing and approach to modifications, (c) nature of context and content modifications, and (d) fidelity in modifications. The Behavioral Activation for Family Caregiver Connectedness intervention addresses unique barriers to caregiver social connection with individualized value-based plans. Modifications to content and delivery reflect the goal of improving intervention fit in the context of social connectedness experienced by informal caregivers.
