The purpose of this study was to develop a Self-Efficacy Scale for Rehabilitation Management designed specifically for postoperative lung cancer patients (SESPRM-LC) and to evaluate its psychometric properties.
Based on the concept of self-management of chronic disease, items were developed from literature review and semistructured interviews of 10 lung cancer patients and screened by expert consultation and pilot testing. Psychometric evaluation was done with 448 postoperative lung cancer patients recruited from 5 tertiary hospitals in Fuzhou, China, by incorporating classical test theory and item response theory methods.
A 6-factor structure was illustrated by exploratory factor analysis and confirmed by confirmatory factor analysis, explaining 60.753% of the total variance. The SESPRM-LC achieved Cronbach's α of 0.694 to 0.893, 2-week test-retest reliability of 0.652 to 0.893, and marginal reliability of 0.565 to 0.934. The predictive and criterion validities were demonstrated by significant association with theoretically supported quality-of-life variables (r = 0.211-0.392, P < .01), and General Perceived Self-efficacy Scale (r = 0.465, P < .01), respectively. Item response theory analysis showed that the SESPRM-LC offers information about a broad range of self-efficacy measures and discriminates well between patients with high and low levels of self-efficacy.
We demonstrated initial support for the reliability and validity of the 27-item SESPRM-LC, as a developmentally appropriate instrument for assessing self-efficacy among lung cancer patients during postoperative rehabilitation.
本研究旨在开发一种专门为肺癌术后患者设计的康复管理自我效能量表（SESPRM-LC），并评估其心理测量特性。
基于慢性病自我管理的概念，通过文献回顾以及对10例肺癌患者的半结构式访谈来制定条目，并经专家咨询和预试验进行筛选。采用经典测验理论和项目反应理论方法，对从中国福州5家三级医院招募的448例肺癌术后患者进行心理测量学评估。
探索性因素分析显示为6因素结构，并经验证性因素分析确认，解释了总方差的60.753%。SESPRM-LC的Cronbach's α系数为0.694至0.893，2周重测信度为0.652至0.893，边际信度为0.565至0.934。预测效度和效标效度分别通过与理论上支持的生活质量变量显著相关（r = 0.211 - 0.392，P <.01）以及与一般自我效能量表（r = 0.465，P <.01）得以证明。项目反应理论分析表明，SESPRM-LC提供了关于广泛自我效能测量的信息，并且能够很好地区分自我效能水平高和低的患者。
我们证明了27项SESPRM-LC在可靠性和有效性方面获得初步支持，它是评估肺癌患者术后康复期间自我效能的一种适合的工具。
