Objectives: This pilot study aimed to assess the feasibility, acceptability, and preliminary effects of a family-based psychoeducational intervention for patients undergoing hemodialysis (HD) and their family members. Methods: This was a single-group (six dyads), six-week, pre-post pilot study, delivered in a multifamily group format. Feasibility was based on screening, eligibility, content, retention, completion, and intervention adherence rates. Acceptability was assessed at post-intervention through a focus group interview.
