Many individuals with COPD develop a lack of confidence regarding their ability to avoid breathing difficulty while participating in certain activities, however minimal the physical demands of the activity may be. This lack of confidence may be expressed as low self-efficacy. As a result of low self-efficacy, COPD patients may refrain from many routine activities of daily living. Identifying situations in which individuals with COPD experience low self-efficacy would allow the development of specific treatment interventions designed to increase the patient's self-efficacy in those situations and consequently increase activity. We developed a 34-item COPD Self-Efficacy Scale (CSES) to assess self-efficacy in individuals afflicted with COPD. The CSES has good test-retest reliability (r = .77), excellent internal consistency (Cronbach's alpha = .95), and a five-factor structure (negative affect, intense emotional arousal, physical exertion, weather/environmental, and behavioral risk factors.
许多慢性阻塞性肺疾病（COPD）患者对自己在参与某些活动时避免呼吸困难的能力缺乏信心，无论这些活动对身体的要求有多低。这种信心的缺乏可能表现为自我效能感低。由于自我效能感低，COPD患者可能会避免许多日常生活中的常规活动。识别COPD患者自我效能感低的情况，将有助于开发特定的治疗干预措施，旨在提高患者在这些情况下的自我效能感，从而增加活动量。我们开发了一个包含34个条目的COPD自我效能量表（CSES），以评估COPD患者的自我效能感。CSES具有良好的重测信度（r = 0.77）、出色的内部一致性（克朗巴哈系数α = 0.95）以及五因素结构（消极情绪、强烈情绪唤起、体力消耗、天气/环境和行为风险因素）。
