The IC-Growth intervention is one of the few manualized psychosocial program in Greece dedicated exclusively to Post-Traumatic Growth. At its core lies Acceptance and Commitment Therapy (ACT), a modern form of Cognitive-Behavioral Therapy that helps patients accept difficult emotions and focus on values and goals that bring meaning to life. ACT is combined with relaxation, mindfulness, and social support techniques, creating a comprehensive intervention tailored to the needs of cancer patients.
