Abstract: Importance: Collaboration between occupational therapists and family caregivers is essential during home assessments and modifications. The shift to videoconferencing-based assessments suggests increased family caregiver involvement, but the specifics of this change are unclear. Objective: To investigate family caregiver involvement during videoconferencing-based home assessments and subsequent modifications from the perspective of occupational therapists. Design: This descriptive qualitative study involved virtual, semistructured individual interviews with participants who were recruited through purposeful and snowball sampling. Data analysis followed a descriptive thematic analysis methodology with an inductive approach. SETTING: All interviews were conducted virtually at each participant's preferred time and location. Participants: Fifteen occupational therapists from the Veterans Health Administration (VHA) with experience in videoconferencing-based home assessments and subsequent modifications for rural veterans. Results: Four key themes were identified: (1) increased active involvement of family caregivers during the home assessment process, (2) circumstances that require family caregiver involvement for videoconferencing, (3) family caregiver-related factors affecting outcomes, and (4) strategies for effective family caregiver involvement. Conclusions and relevance: The findings suggest that veterans' family caregivers play a more active role during videoconferencing-based home assessments than they do during traditional in-person assessments. This increased involvement may lead to a higher workload for VHA occupational therapists, who should now train caregivers, and for family caregivers themselves, who need to perform tasks previously handled by occupational therapists during home visits. To address this challenge, occupational therapists can leverage the insights extracted from this study.
