Psychological functioning of adults with cystic fibrosis.

STUDY OBJECTIVES The purpose of this study is to assess the psychological profiles of adult patients with cystic fibrosis (CF) and to investigate predictors of patients' psychological status. PATIENTS AND METHODS Thirty-four adults with CF completed a battery of psychological testing including the Minnesota Multiphasic Personality Inventory-2, Beck Depression Inventory, and State-Trait Anxiety inventory. These were compared to health status data, including pulmonary function testing and nutritional status measures. RESULTS As a group, adults with CF did not demonstrate significant levels of depression, anxiety, or other psychopathology. Results were not affected by age, sex, or severity of disease. Male gender predicted higher scores for depression and anxiety, and better lung functioning predicted less anxiety. Having a higher level of psychosocial support emerged as a strong predictor of better psychological functioning. CONCLUSIONS Overall, adults with CF report relatively healthy psychological functioning. Better lung function and a strong social support system predicted better psychological functioning, which may have implications for clinical intervention.
