BACKGROUND: Technology can enhance support for families caring for persons living with dementia but must be acceptable to be adopted. The FamTechCare clinical trial engaged caregivers in video recording care encounters that were reviewed by an expert panel who provided tailored feedback. The intervention reduced caregiver depression and improved caregiver competence. This mixed methods study reports on caregiver satisfaction and utilization of the intervention and expert panel evaluation of the intervention. METHODS: A convergent parallel mixed methods design was used to evaluate the satisfaction, usability, and feasibility of the FamTechCare intervention. In the multisite randomized controlled trial, caregiver-person living with dementia dyads were randomized to the FamTechCare video support or attention control telephone support groups. Caregivers completed a satisfaction survey at the completion of the 3-month trial. Utilization was evaluated using the number and duration of videos submitted and calls received by caregivers. Relationships between participant characteristics and their satisfaction and utilization were evaluated. Feasibility of the intervention was assessed through content analysis of interviews with the expert panel. RESULTS: The majority of caregivers in both groups reported benefits from participation. More FamTechCare caregivers found the interventionist support to be helpful ( = 0.001) and effective ( = 0.020) compared to attention control caregivers. FamTechCare caregivers of persons with more severe dementia were more likely to report that video recording intruded on their privacy ( = 0.050). Caregiver age, gender, education, dyad relationship, rural status, and type and severity of dementia were not associated with ratings of acceptability, ease of use, or intervention utilization. The expert panel described the FamTechCare intervention as useful and identified adaptations to enhance feasibility. CONCLUSION: Regardless of age, gender, and relationship, caregivers found the intervention acceptable and easy to use and rated the expert feedback as effective in addressing care challenges. Further adaptation may be needed for FamTechCare to be readily implemented.
