To determine whether perceived uncertainty and physical symptoms were related to negative mood in hospitalized patients with chronic bronchitis and/or emphysema.
Descriptive correlational.
Five large teaching hospitals in a city in central Canada.
The sample consisted of 15 men and 11 women ranging in age from 53 to 86 years.
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.
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.
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.
确定在患有慢性支气管炎和/或肺气肿的住院患者中，感知到的不确定性和身体症状是否与负面情绪相关。
描述性相关性研究。
加拿大中部一个城市的五家大型教学医院。
样本包括15名男性和11名女性，年龄在53岁至86岁之间。
米歇尔疾病不确定感量表；支气管炎肺气肿症状清单的躯体量表；以及情绪状态剖面图的紧张、抑郁和愤怒分量表。
只有身体症状这一变量导致了慢性阻塞性肺疾病患者的负面情绪，解释了21%的方差（p < 0.02）。在所测量的四类症状（疲劳、呼吸困难、充血和周围感觉障碍）中，只有疲劳是负面情绪的显著预测因素（p < 0.006），占方差的28%。
负面情绪是应对能力受损的证据。疲劳导致负面情绪这一发现为低能量会干扰个体应对压力情境的能力这一理论预测提供了支持。
