Background/Objectives: Cystic fibrosis (CF) is a chronic genetic disease that impacts both physical and psychological health, increasing vulnerability to anxiety, depression, and reduced quality of life (QoL). Psychological interventions, particularly cognitive behavioral therapy (CBT), have demonstrated promising results in enhancing emotional resilience, treatment adherence, and QoL. This systematic review aims to evaluate the role and effectiveness of psychological interventions in improving the QoL among individuals with CF. Methods: A comprehensive literature search was conducted across the PubMed, Scopus, and PsycINFO databases for studies published between 2014 and 2024, in line with PRISMA guidelines and a registered PROSPERO protocol. Out of 162 initially identified articles, six clinical studies met the inclusion criteria. Intervention included cognitive behavioral therapy-based interventions, employing several digital or telehealth formats such as fibrosis-specific cognitive behavioral therapy (CF-CBT) and the coping and learning to manage stress (CALM) program, often delivered via telehealth. Results: Most interventions demonstrated significant reductions in depression, anxiety, and perceived stress, alongside improvements in coping self-efficacy and vitality. Cohen's d-effect sizes ranged from moderate to large for core psychological outcomes. QoL measures, particularly vitality and emotional functioning, were significantly enhanced in most studies. Conclusions: Psychological interventions, particularly CBT and ACT, significantly improve mental health and QoL in individuals with CF, supporting their integration into routine care.
