Results of a pilot randomized controlled trial: A couple-based meditation intervention for patients with metastatic lung cancer and their partners.

Abstract

135 Background: Although mindfulness-based interventions have been widely examined in patients with early stage cancer, the feasibility and efficacy of these types of programs are largely unknown in the palliative care setting. We developed a couple-based intervention integrating meditation training with emotional disclosure exercises to target psychological distress in patients with metastatic lung cancer and their partners. Methods: Dyads completed baseline self-report measures and were then randomized to a couple-based meditation (CBM), a supportive-expressive (SE), or a waitlist control (WLC) group. Couples in the CBM and ES groups attended 4 weekly, 60 min. therapist-led sessions that were delivered via FaceTime. All groups were reassessed 1 month and 3 months later. Results: Seventy-five patients (51% female; mean age = 64 years) and their partners’ (52% female; mean age = 64 years) were randomized (63% consent rate) of which 79% completed the first and 65% completed the second follow-up assessments. Attrition was mainly due to patients’ death (44%). Although attendance was high in both groups (means: CBM = 3.12; SE = 3.08), dyads in the CBM group indicated greater benefit (P < .003) and usefulness (P < .05) of the sessions compared to those in the SE group. Compared with the WLC group, patients in the CBM group reported significantly lower depressive symptoms (P = .02; d = .49; CES-D means: CBM = 7.87; SE = 11.51; WLC = 12.76) and cancer specific distress (P = .05; d = .44; IES means: CBM = 12.40; SE = 16.34; WLC = 18.22). Similarly, compared with the WLC group, partners in the CBM group reported significantly lower depressive symptoms (P = .02; d = .58; means: CBM = 7.18; AC = 8.91; WLC = 11.62). For both patients and partners, there were no effects between SE and WLC groups. While small effects (d = .22-.42) in favor of the CBM group relative to the SE group were revealed, these differences were not significant. Conclusions: It seems to be feasible, acceptable and possibly efficacious to deliver dyadic interventions via FaceTime to couples coping with metastatic lung cancer. Mindfulness-based interventions may be of value to manage symptom burden in the palliative care setting. Clinical trial information: NCT02596490.
