[Perception of illness and dispositional optimism in a sample of patients with chronic heart failure]

INTRODUCTION. Psychological research on Chronic Heart Failure has mainly focused on the patient's emotional status, particularly on anxiety and depression.

To describe the psychological characteristics of a sample of hospitalized CHF inpatients and to assess their illness perception and their dispositional optimism and pessimism, and the mutual relations among these variables.

77 CHF inpatients of a Department of Cardiovascular Rehabilitation (aged 57.4 +/- 10.0) were consecutively enrolled. The following psychological constructs were assessed: anxiety (HADS-A), depression (BDI-II: total score, Cognitive and Affective Factors), illness perception (Brief IPQ) and dispositional optimism and pessimism (LOT-R). Correlations between Brief IPQ and LOT-R data were calculated and subsequently ANOVAs were performed on Brief IPQ and LOT-R data divided by sex, anxiety and depression. RESULTS. As to anxiety, 57 (74.0%) patients resulted not anxious, whereas 10 (13.0%) reported light anxious symptomatology, 8 (10.4%) moderate and 2 (2.6%) severe. Thirty nine patients (50.7%) resulted not depressed, whereas 19 (24.7%) resulted severely depressed. Significant correlations emerged among dispositional pessimism (LOT-R) and the following Brief IPQ variables: Treatment Control (r = - 0.40 p < 0.0001) and Coherence (r = -0.35 p = 0.002). Anxiety and depression differentiated the sample considering illness perception but not dispositional optimism and pessimism. CONCLUSIONS. As to anxiety and depression our data enlighten the presence of emotional disorders in CHF patients. Moreover illness perception differentiates the sample when analysed considering the emotional status. Interesting are the relationships among illness representations and dispositional pessimism, which deserve further studies. In our sample pessimism seems not to be opposed, in a bipolar construct, to optimism and results not related to depression; besides pessimism might have a predictive role in patient's disease management in a not yet explored direction. Finally our data confirm what usually qualitatively observed in clinical practice during the psychological intervention in rehabilitation cardiology. They also provide scientific information on the utility of an accurate psychological screening and a consequent specific intervention aimed at both providing psychological support and cognitive restructuring.
