Psychological determinants of treatment adherence in adults with Cystic Fibrosis / Lisa Kettler.

Abstract

This study demostrates that adherence to treatment in adults with cystic fibrosis (CF) varies significantly between treatments, and is influenced by the beliefs and perceptions that patients hold about both their disease and its treatment. Using a newly developed questionnaire, the Cystic Fibrosis Perceptions Inventory, the beliefs and perceptions that adults with CF hold about their disease was explored. Perceptions about the value of treatments, and whether the costs of adherence to treatment outweighed the benefits, were significantly associated with self-reported and electronically monitored adherence to several CF treatments. Adherence to less complex treatments was associated with concerns about CF, and heightened attention to the disease and treatment process.
