Couple-based mind-body intervention for patients with metastatic lung cancer and their spouses.
179 Background: Given the incurable nature of metastatic lung cancer, patients and their spouses are at risk of experiencing psychological and spiritual distress. To address these concerns, we developed a couple-based mind-body (CBMB) intervention. This formative research aimed to examine intervention acceptability and initially efficacy in patients with metastatic lung cancer undergoing treatment and their spouses. Methods: We first conducted focus groups followed by a single-arm trial. Focus group participants completed program exercises and then semi-structured interviews and written evaluations including Likert-scale and open-ended questions. In the single-arm trial, the four intervention session were delivered over a 2-week period focusing on cultivating mindfulness, interpersonal connection, gratitude and purpose. Couples completed measures of depressive symptoms (CES-D), cancer distress (IES), spiritual well-being (FACT-Sp) and sleep disturbances (PSQI) before and after the program. Results: Focus groups (n = 7 dyads) revealed high acceptability ratings of the CBMB intervention (e.g., all participants would recommend the intervention). Consent and adherence rates (54% and 67%, respectively) were acceptable for the single arm trial (n = 7 dyads). All patients (67% male; µ age = 55 years) and partners (33% male; µ age = 59 years) rated the intervention as useful. Paired t-test analyses revealed large effects for sleep disturbances ( d= 1.83) and medium effects for cancer distress ( d= .61) for patients and large effects for depressive symptoms for spouses ( d= .90). Conclusions: Based on this two part study, the CBMB intervention appears to be acceptable and subjectively useful. There was also preliminary evidence regarding treatment gains for both patients and partners. A randomized controlled trial is warranted to further examine this supportive care strategy.
