Mapping the evidence on dignity therapy in amyotrophic lateral sclerosis: a scoping review

Objective: To systematically map and synthesize the existing literature on the use of Dignity Therapy (DT) in amyotrophic lateral sclerosis (ALS), with particular attention to feasibility, acceptability, therapeutic outcomes, and clinical adaptations required for patients and caregivers. Methods: A systematic scoping review was conducted searching PubMed/MEDLINE, CINAHL, PsycINFO, and Scopus for studies published in the last ten years examining DT in individuals with ALS. Eligible studies were charted and compared qualitatively due to heterogeneity in design, outcomes, and measurement tools. Results: A total of 237 records were identified, of which five met the eligibility criteria. DT was generally feasible in ALS, including in advanced disease stages, when adapted with augmentative communication devices, email correspondence, or videoconferencing. Acceptability was high across studies, with participants frequently reporting meaningful engagement with the narrative process and positive perceptions of the generativity document. Qualitative evidence indicated potential benefits in existential well-being, emotional adjustment, maintenance of identity, and family communication. Quantitative outcomes were inconsistent, showing variable effects on dignity-related distress, mood symptoms, and spiritual well-being. Caregiver responses were mixed, with some reporting perceived support and others noting limited immediate impact. Conclusions: DT appears to be a promising intervention for addressing existential and relational needs in ALS, though current evidence is limited by small sample sizes and methodological variability. Larger, methodologically rigorous studies are needed to clarify therapeutic effects, optimize delivery adaptations, and evaluate outcomes for both patients and caregivers.
