Effectiveness of A Multi-Component Self-Management Intervention for Anxiety and Respiratory-Related Symptoms in Patients With Lung Cancer

The study aims to examine the effectiveness of M-RDSI (Mindfulness-Respiratory Distress Symptom Intervention) in Hong Kong (HK) Chinese patients with lung cancer (LC). Investigators will conduct a three-arm mixed-methods randomized controlled trial (RCT) involving 189 patients with LC.The three groups are M-RDSI, RDSI (Respiratory Distress Symptom Intervention), and usual care. The M-RDSI group includes standard RDSI training sessions, along with four additional 30-minute sessions dedicated to practicing core exercises from MBCT. These sessions are facilitated by a trained nurse and will be held at the hospital or PolyU, depending on the participants' preferences. The RDSI group will receive four evidence-based components at the hospital or PolyU, depending on the participants' preferences. The usual care group will receive health educational booklets based on the original RDSI materials, which have been adapted for HK LC patients.The study will be conducted at Chinese University of HK, Prince of Wales Hospital. Data collection will be conducted at baseline, week 6, and week 12 after the completion of the intervention. Multiple assessment timepoints will capture changes over time.
