A randomized controlled trial on the efficacy of life review therapy targeting incurably ill cancer patients: do their informal caregivers benefit?

PURPOSE: Investigate whether Life Review Therapy and Memory Specificity Training (LRT-MST) targeting incurably ill cancer patients may also have a beneficial effect on caregiving burden, symptoms of anxiety and depression, and posttraumatic growth of the informal caregivers. METHODS: Data was collected in the context of a randomized controlled trial (RCT) (secondary analyses) on the effect of LRT-MST among incurably cancer patients. Informal caregivers of participating patients were asked to complete outcome measures at baseline (T0), post-intervention (T1), and 1-month follow-up (T2): caregiver burden (caregivers reaction assessment scale (CRA)), symptoms of anxiety and depression (hospital anxiety and depression scale), and posttraumatic growth (posttraumatic growth inventory). Linear mixed models (intention to treat) were used to assess group differences in changes over time. Effect size and independent samples t tests were used to assess group differences at T1 and T2. RESULTS: In total, 64 caregivers participated. At baseline, 56% of the caregivers experienced anxiety and 30% depression. No significant effect was found on these symptoms nor on posttraumatic growth or most aspects of caregiver burden. There was a significant effect of LRT-MST on the course of self-esteem (subscale CRA) (p = 0.013). Effect size was moderate post-intervention (ES = - 0.38, p = 0.23) and at 3-month follow-up (ES = 0.53, p = 0.083). CONCLUSIONS: Many caregivers of incurably ill cancer patients experience symptoms of anxiety and depression. LRT-MST does not improve symptoms of depression and anxiety, negative aspects of caregiver burden, or posttraumatic growth. LRT-MST may have a protective effect on self-esteem of informal caregivers (positive aspect of caregiver burden).

Patients' experiences of life review therapy combined with memory specificity training (LRT-MST) targeting cancer patients in palliative care.

PURPOSE: Life review therapy combined with memory specificity training (LRT-MST) is effective in cancer patients in palliative care, but the effect size is moderate. The aim of this qualitative study was to obtain more in-depth knowledge on motivation to start with LRT-MST, experiences with LRT-MST, and perceived outcomes of LRT-MST. METHODS: Semi-structured interviews were conducted with 20 cancer patients in palliative care who participated in a randomized controlled trial investigating the effect of LRT-MST. All interviews were digitally recorded and transcribed verbatim. Data were analyzed by means of thematic analysis independently by two coders and coded into key issues and themes. RESULTS: Patients started LRT-MST for intrinsic (e.g., potential benefit for personal well-being) and extrinsic reasons (e.g., potential benefit for future patients). Patients indicated mainly positive experiences with the intervention. They appreciated sharing their memories and regaining memories with a specific focus on retrieving positive memories. Some disliked the fact that negative memories could not be addressed. Most patients perceived positive outcomes of the intervention belonging to the overarching themes "ego-integrity" and "psychological well-being" in the here and now, as well as in the nearby future (including end-of-life). CONCLUSIONS: LRT-MST is of added value as a psychological intervention in palliative care. This study provided in-depth insight into reasons to start the intervention, and the experiences and outcomes, which are important to further tailor LRT-MST and for development or improvement of other psychological interventions targeting cancer patients in palliative care.

The efficacy of Life Review Therapy combined with Memory Specificity Training (LRT-MST) targeting cancer patients in palliative care: A randomized controlled trial.

BACKGROUND: The aim of this study was to evaluate the efficacy of an intervention combining Life Review Therapy (LRT) and Memory Specificity Training (MST) (LRT-MST) to improve ego-integrity and despair among cancer patients in palliative care. METHODS: In this multicentre randomized controlled trial, cancer patients in palliative care were randomized to the intervention group (LRT-MST; n = 55) or waiting-list control group (n = 52). LRT-MST is a 4-session home-based psychological intervention that aims to retrieve specific positive memories, to re-evaluate life events and to reconstruct the story of a patient's life, including the diagnosis of incurable cancer. Outcome measures were ego-integrity and despair (NEIS), psychological distress, anxiety and depression (HADS), quality of life (EORTC QLQ-C15-PAL), and specificity of the autobiographical memory (AMT). NEIS, HADS and EORTC QLQ-C15-PAL were assessed at baseline (T0), 1 month later (post-treatment; T1), and at 1 month follow-up (T2). AMT was assessed at T0 and T1. Linear mixed models (intention to treat) were used to assess group differences in changes over time. Independent samples t-tests were used to assess group differences at T0, T1, and T2, and effect sizes (ES) were calculated at T1 and T2. RESULTS: The course of ego-integrity (not despair) improved significantly over time (p = .007) in the intervention group compared to the waiting-list control group, with moderate, but insignificant, effect sizes at T1 (ES = .42) and T2 (ES = .48). Compliance rate was 69% and total dropout rate was 28%, both primarily related to disease progression and death. CONCLUSIONS: LRT-MST seems effective among cancer patients in palliative care to improve the course of ego-integrity.

Effectiveness and cost-effectiveness of meaning-centered group psychotherapy in cancer survivors: protocol of a randomized controlled trial.

BACKGROUND: Meaning-focused coping may be at the core of adequate adjustment to life after cancer. Cancer survivors who experience their life as meaningful are better adjusted, have better quality of life and psychological functioning. Meaning-Centered Group Psychotherapy for Cancer Survivors (MCGP-CS) was designed to help patients to sustain or enhance a sense of meaning and purpose in their lives. The aim of the proposed study is to evaluate the effectiveness and cost-effectiveness of MCGP-CS. METHODS/DESIGN: Survivors diagnosed with cancer in the last 5 years and treated with curative intent, are recruited via several hospitals in the Netherlands. After screening, 168 survivors are randomly assigned to one of the three study arms: 1. Meaning-Centered Group Psychotherapy (MCGP-CS) 2. Supportive group psychotherapy (SGP) 3. Care as usual (CAU). Baseline assessment takes place before randomisation, with follow up assessments post-intervention and at 3, 6 and 12 months follow-up. Primary outcome is meaning making (PMP, PTGI, SPWB). Secondary outcome measures address quality of life (EORTC-30), anxiety and depression (HADS), hopelessness (BHS), optimism (LOT-R), adjustment to cancer (MAC), and costs (TIC-P, EQ-5D, PRODISQ). DISCUSSION: Meaning-focused coping is key to adjustment to life after cancer, however, there is a lack of evidence based psychological interventions in this area. Many cancer survivors experience feelings of loneliness and alienation, and have a need for peer support, therefore a group method in particular, can be beneficial for sustaining or enhancing a sense of meaning. If this MCGP-CS is effective for cancer survivors, it can be implemented in the practice of psycho-oncology care. TRIAL REGISTRATION: Netherlands Trial Register, NTR3571.
