This study explores the psychometric properties of the Exercise Self-Efficacy (ESE) scale among individuals with Chronic Obstructive Pulmonary Disease (COPD). The secondary objective was to evaluate the relationship between self-efficacy, functional exercise capacity, health-related quality of life and psychological state in the same population.
This cross-sectional study was carried out in primary care centers in Spain. The sample was comprised of 156 people with COPD in whom anthropometric and clinical information was recorded. The ESE scale and other measures on functional exercise capacity, psychological state and health-related quality of life were administered. Psychometric properties were assessed through construct validity (EFA, exploratory factor analysis; CFA, confirmatory factor analysis), internal consistency, floor/ceiling effects and convergent validity. In this way, a quantitative, predictive and correlational research was carried out.
The EFA ruled out the structure of a single factor (Barletts's test p < 0.001, Kaiser-Meyer-Olkin 0.9). ACF suggested that the most appropriate adjustment model was the two-factor solution (comparative fit index = 0.967, Tucker-Lewis index = 0.961, root mean square approximation = 0.075, standardized root mean square residual = 0.058). Thus, ESE scale is best interpreting using 15 items distributed in 2 factors ("physical and occupational/environmental barriers" and "psychosocial barriers") than explained to 56.7% of the variance. With regard to reliability, Cronbach's alpha was = 0.92 and no floor or ceiling effects were observed. The scale showed a moderate/strong correlation with functional exercise capacity (r = 0.41), health-related quality of life (r= - 0.53) and psychological status (r= - 0.63).
The psychometric testing of the ESE scale provided support for the reliability and validity of the instrument in individuals with COPD. The ESE scale score shows a moderate positive correlation with functional exercise capacity and a negative correlation with health-related quality of life. In addition to a strong correlation with psychological status. In future research, the predictive power of the ESE scale in adherence to non-pharmacological treatment could be studied.
本研究探讨慢性阻塞性肺疾病（COPD）患者运动自我效能（ESE）量表的心理测量特性。次要目的是评估同一人群中自我效能、功能性运动能力、健康相关生活质量和心理状态之间的关系。
本横断面研究在西班牙的初级保健中心进行。样本包括156名COPD患者，记录了他们的人体测量和临床信息。采用ESE量表以及其他关于功能性运动能力、心理状态和健康相关生活质量的测量方法。通过结构效度（探索性因素分析EFA、验证性因素分析CFA）、内部一致性、地板/天花板效应和收敛效度来评估心理测量特性。通过这种方式，进行了一项定量、预测性和相关性研究。
探索性因素分析排除了单因素结构（Bartlett检验p＜0.001，Kaiser-Meyer-Olkin值为0.9）。验证性因素分析表明最合适的调整模型是双因素解决方案（比较拟合指数=0.967，Tucker-Lewis指数=0.961，均方根近似值=0.075，标准化均方根残差=0.058）。因此，ESE量表最好用分布在两个因素（“身体和职业/环境障碍”和“心理社会障碍”）中的15个项目来解释，其解释了56.7%的方差。关于信度，Cronbach's alpha系数为0.92，未观察到地板或天花板效应。该量表与功能性运动能力（r = 0.41）、健康相关生活质量（r = -0.53）和心理状态（r = -0.63）呈中度/强相关性。
ESE量表的心理测量测试为该工具在COPD患者中的可靠性和有效性提供了支持。ESE量表得分与功能性运动能力呈中度正相关，与健康相关生活质量呈负相关。此外，与心理状态呈强相关性。在未来的研究中，可以研究ESE量表在坚持非药物治疗方面的预测能力。
