Pilot of a therapist-guided digital mental health intervention (eHealth CF-CBT) for adults with cystic fibrosis.

Background: eHealth CF-CBT is the first digital mental health intervention for depression/anxiety in adults with cystic fibrosis (awCF); an 8-session therapist-guided internet-delivered program that was developed in English and Dutch with stakeholder input and evaluation indicating high acceptability and usability.

Methods: Dutch eHealth CF-CBT was piloted in awCF with mild-moderate symptoms of depression and/or anxiety. Feasibility, usability, acceptability, and preliminary efficacy were assessed, measuring pre-post changes in depression (PHQ-9), anxiety (GAD-7), perceived stress (PSS), and health-related quality of life (CFQ-R).
