Emotional skills are the ability to use emotions cleverly in daily life. Good emotional skills are associated with better mental and physical health in healthy and clinical populations. However, to our knowledge, cancer patients have never benefited from an intervention aiming at increasing their emotional skills. Our goal was thus to design and test such an intervention. A prospective, multi-center, randomized controlled trial (RCT) will be conducted in esogastric and lung cancer patients after antineoplastic treatments. Forty-three patients are expected in each arm. The primary outcome is the change in emotional skills assessed using a patient-reported validated questionnaire between the start and two weeks after the end of the intervention and at 2-month follow-up. The experimental arm will have to follow three individual sessions on emotional skills (i.e. identification, understanding, expression and regulation of emotions) while the control arm will have to follow three sessions of relaxation. In each arm, the first session can be held face to face or over the phone and the last two sessions will be held over the phone. Patients have exercises to practice in between sessions.It is hypothesised that the experimental group will experience a greater increase in emotional skills than the control group.
