In 50 patients with chronic bronchitis the relation was assessed between exercise tolerance and pulmonary function and psychological factors, including subjective perception of exertion, mood, general psychiatric disturbance, and the attitudes and beliefs held by patients concerning themselves, their illness, and its treatment. Ventilatory capacity was significantly correlated with but a poor predictor of exercise tolerance. Subjective perception of exertion was most closely correlated with exercise tolerance. The distance walked in a 12-minute exercise test was significantly correlated with measurements of mood and with several attitudes and beliefs. Attitudes and beliefs greatly outweighed measurements of mood and ventilatory capacity as components in a multiple regression predicting distance walked in 12 minutes. This method of psychological assessment emphasises the importance of attitudes and beliefs in respiratory disability and may have useful applications in rehabilitation in other chronic diseases.
在50例慢性支气管炎患者中，对运动耐量与肺功能及心理因素之间的关系进行了评估，这些心理因素包括主观用力感觉、情绪、一般精神障碍以及患者对自身、疾病及其治疗的态度和信念。通气能力与运动耐量显著相关，但作为运动耐量的预测指标效果不佳。主观用力感觉与运动耐量的相关性最为密切。12分钟运动试验中行走的距离与情绪测量值以及几种态度和信念显著相关。在预测12分钟行走距离的多元回归分析中，态度和信念作为因素，其影响力大大超过了情绪测量值和通气能力。这种心理评估方法强调了态度和信念在呼吸功能障碍中的重要性，并且可能在其他慢性疾病的康复中具有实用价值。
