Influence of symptoms, lung function, mood, and social support on level of functioning of patients with COPD.

To explain how symptoms, lung function, mood, and social support affect level of functioning, patients (N = 143) with chronic obstructive pulmonary disease (COPD) completed measures assessing their symptoms (Bronchitis-Emphysema Symptom Checklist), mood (Profile of Mood States), social support (Personal Resource Questionnaire), and functioning (Sickness Impact Profile). Those who were receiving oxygen therapy (n = 52) had significantly lower FEV1 scores and experienced significantly poorer functioning than those who were not receiving oxygen therapy (n = 91). Results of path analyses indicated that symptoms and mood directly, and social support indirectly, influenced the functioning of those who were not receiving oxygen. For those who were receiving oxygen, only symptoms directly, and FEV1 indirectly, influenced their functioning. These models need to be confirmed using other samples of patients with COPD.

Effects of psychological well-being, physical status, and social support on oxygen-dependent COPD patients' level of functioning.

Thirty oxygen-dependent patients with chronic obstructive pulmonary disease (COPD) participated in a descriptive correlational study in which investigators examined the relationship between oxygen-dependent COPD patients' psychological well-being, physical status, social support, and level of functioning. Lazarus and Folkman's (1984) theory of psychological stress and coping was used to guide the study. Using multiple regression analysis, physical symptoms had the most predictive power in relation to the level of functioning, accounting for 44.3% of the variance. Among the symptoms, dyspnea had the greatest influence on functioning.

Sickness impact profile: a measure of dysfunction with chronic pain patients.

Although chronic pain may affect all facets of a patient's life, there is no generally accepted method of measuring the extent of the disability experienced. This component of a larger study examined changes in usual activities and relationships for patients experiencing chronic nonmalignant pain, in order to understand the impact of pain on an individual's life. The effect of pain intensity and depression on the performance of usual daily activities was assessed by the Sickness Impact Profile (SIP). The sample of 34 subjects, 17 women and 17 men, rated their pain as moderate to severe on a linear analogue scale (mean 64). Thirty percent of subjects were moderately to severely depressed as measured by the Beck Depression Inventory (mean 21). The SIP scores indicated severe disruption in daily activities and relationships for this sample. Significant correlations between the SIP and visual analogue scales measuring coping adequacy and activity levels were interesting and warrant further study.

Factors that predict patients' functioning following treatment for cancer.

The study assessed whether the extent of cancer patients' functioning following a course of radiotherapy could be predicted from the amounts of concern, emotional distress, social support and symptoms they had when they began the treatments and from the number of unanticipated experiences they had related to receiving radiotherapy. A sample of 79 patients, 58 with breast cancer and 21 with lung cancer, were interviewed at the beginning and following a course of radiotherapy. When their diagnosis and age were controlled statistically, the only variable which predicted the subject's functioning following the radiotherapy was the amount of emotional distress they experienced when they began the treatments. An examination of the extent to which the individual components of emotional distress contributed to the subjects' functioning revealed that the tension-anxiety component of the emotional distress score was the best predictor of their functioning.

Perceived uncertainty, physical symptoms, and negative mood in hospitalized patients with chronic obstructive pulmonary disease.

OBJECTIVE: To determine whether perceived uncertainty and physical symptoms were related to negative mood in hospitalized patients with chronic bronchitis and/or emphysema. DESIGN: Descriptive correlational. SETTING: Five large teaching hospitals in a city in central Canada. SUBJECTS: The sample consisted of 15 men and 11 women ranging in age from 53 to 86 years. INSTRUMENTS: Mishel Uncertainty in Illness Scale; Somatic Scale of the Bronchitis Emphysema Symptom Checklist; and Tension, Depression and Anger Subscales of the Profile of Mood States. RESULTS: Only the variable of physical symptoms contributed to the negative mood of the subjects with chronic obstructive pulmonary disease, explaining 21% of the variance (p < 0.02). Of the four symptom categories measured (fatigue, dyspnea, congestion, and peripheral-sensory disturbance), only fatigue was a significant predictor (p < 0.006) of negative mood, accounting for 28% of the variance. CONCLUSION: Negative mood is evidence of impaired coping. The finding that fatigue contributed to negative mood provides support for the theoretic prediction that low energy interferes with an individual's ability to cope with a stressful situation.
