Lung cancer and its prolonged treatment are profoundly unsettling for patients and their family caregivers, and developing dyadic measures to alleviate their negative affectivity is pivotal. This study aimed to develop a complex intervention to alleviate dyadic psychological stress among patients with lung cancer and their family caregivers.

A stepwise multi-method study was conducted following the Medical Research Council framework. Three phases were adopted, namely: (1) a preparation phase, a systematic review was conducted to identify the evidence base, (2) a development phase, empirical data from a quantitative study and a qualitative study were integrated to identify effective components, and (3) a modification phase, an online Delphi survey was carried out to refine the intervention.

The dyadic Mindfulness Self-Compassion intervention developed in this study consists of six weekly sessions. The key components of the intervention include: (1) getting along with cancer (introductory session targets illness perception), (2) practising mindful awareness (core session for mindfulness), (3) defining dyadic relationships and introducing self-compassion (core session for self-compassion), (4) promoting dyadic communication (maintenance session targets communication skills), (5) promoting dyadic coping (maintenance session targets coping skills), and (6) a summary session reviewing the rewards and challenges of dyadic adaptation named embracing the future.

An evidence-based, theory-driven, and culturally appropriate dyadic Mindfulness Self-Compassion intervention was developed for patients with lung cancer and their family caregivers. Future studies are warranted to pilot and evaluate the usability, feasibility, acceptability, satisfaction, and effectiveness of this complex intervention.
