Description
Trial 1 (single-arm study)
• Aim 1: Examine the usability of the intervention content and trial assessments in 10 caregiver-patient dyads to refine study procedures as needed.
Trial 2 (RCT)
Aim 1 (primary aim): Determine the feasibility of implementing a caregiving intervention using a randomized controlled design in 50 caregiver-HGG patient dyads.
Aim 2: Evaluate the initial evidence for intervention efficacy relative to a WLC group regarding patient and caregiver psychological symptoms (primary outcome), caregiver caregiving efficacy and role adjustment, and patient cancer-related symptoms and healthcare utilization (secondary outcomes).
Aim 3: Understand caregivers’ experiences using qualitative methods regarding participation in this study and explore emerging themes as possible intervention mediators/moderators to be examined in future research.
