Effects of remote dignity therapy on mental health among patients with hematologic neoplasms and their significant others: A randomized controlled trial

Families of patients with hematologic neoplasms involved in dignity therapy have exhibited a remarkable improvement in psychological well-being and family functioning. However, the applicability and generalizability of family participatory dignity therapy are limited as it is influenced by factors such as intervention time, place, and participants. Whether remote support from significant others is feasible and effective remains unknown. This study aimed to confirm the efficacy of significant others participating in remote dignity therapy (r-DT) on hope, dignity loss, meaning of life, and sense of stigma among patients with hematologic neoplasms as well as their significant others' depression and anxiety. A randomized, single-blinded, two-arm, parallel-group controlled trial was conducted. Participants included patients with hematologic neoplasms and their significant others, who were recruited from Fujian Medical University Union Hospital from May 2021 to January 2022. A total of 72 eligible participants agreed to participate, and were randomly assigned to an intervention group (n = 35) or a control group (n = 37). Each pair of participants in the intervention group participated in two or three conversations based on the online video function of the WeChat platform, performed by one therapist in accordance with a specific communication outline. To evaluate the effects of the intervention, we assessed the patients' degree of dignity loss, hope level, meaning of life, and sense of stigma, as well as their significant others' depression, anxiety, and intimacy at baseline (T0), 15 days (T1), 30 days (T2), and 60 days (T3), and compared the scores between the two groups after the completion of the intervention. The Generalized Estimation Equation Model (GEE) was used to examine the effects of time, group, and their interaction. The data with only the baseline are eliminated. Ultimately, the analysis comprised 66 pairs of participants. The intervention group statistically significantly differed in lower dignity loss (t = 2.190, p = 0.032), higher hope level (t = − 2.010, p = 0.049), and higher meaning of life (t = − 2.066, p = 0.043) than the control group at T1. Regarding their significant others, the results of the comparison between the two groups showed that significant others in the intervention group had reduced levels of anxiety and depression at T1 and T2 (p < 0.05). The majority of patients (84.38 %) and significant others (75.00 %) provided positive evaluations of the program. The r-DT showed a short-term positive effect on decreasing patients' dignity loss and promoting patients' hope and meaning of life; among their significant others, it decreased anxiety and depression. Registered in the China Clinical Trial Registry on 17 March 2021(ChiCTR2100044374). Remote dignity therapy decreased patients' dignity loss and promoted their hope and meaning of life; among their significant others, it decreased anxiety and depression.
