Abstract

BACKGROUND

No tool exists to measure self-efficacy for overcoming lymphedema-related exercise barriers in individuals with cancer-related lymphedema. However, an existing scale measures confidence to overcome general exercise barriers in cancer survivors. Therefore, the purpose of this study was to develop, validate and assess the reliability of a subscale, to be used in conjunction with the general barriers scale, for determining exercise barriers self-efficacy in individuals facing lymphedema-related exercise barriers.

METHODS

A lymphedema-specific exercise barriers self-efficacy subscale was developed and validated using a cohort of 106 cancer survivors with cancer-related lymphedema, from Brisbane, Australia. An initial ten-item lymphedema-specific barrier subscale was developed and tested, with participant feedback and principal components analysis results used to guide development of the final version. Validity and test-retest reliability analyses were conducted on the final subscale.

RESULTS

The final lymphedema-specific subscale contained five items. Principal components analysis revealed these items loaded highly (>0.75) on a separate factor when tested with a well-established nine-item general barriers scale. The final five-item subscale demonstrated good construct and criterion validity, high internal consistency (Cronbach's alpha = 0.93) and test-retest reliability (ICC = 0.67, p < 0.01).

CONCLUSIONS

A valid and reliable lymphedema-specific subscale has been developed to assess exercise barriers self-efficacy in individuals with cancer-related lymphedema. This scale can be used in conjunction with an existing general exercise barriers scale to enhance exercise adherence in this understudied patient group.

摘要

背景

目前尚无工具可用于测量癌症相关淋巴水肿患者克服与淋巴水肿相关运动障碍的自我效能感。然而，现有的一个量表可测量癌症幸存者克服一般运动障碍的信心。因此，本研究的目的是开发、验证并评估一个子量表的可靠性，该子量表将与一般障碍量表一起用于确定面临与淋巴水肿相关运动障碍的个体的运动障碍自我效能感。

方法

使用来自澳大利亚布里斯班的106名患有癌症相关淋巴水肿的癌症幸存者队列，开发并验证了一个淋巴水肿特异性运动障碍自我效能量表。首先开发并测试了一个包含十个条目的淋巴水肿特异性障碍子量表，并根据参与者的反馈和主成分分析结果来指导最终版本的开发。对最终的子量表进行了效度和重测信度分析。

结果

最终的淋巴水肿特异性子量表包含五个条目。主成分分析表明，当与一个成熟的包含九个条目的一般障碍量表一起测试时，这些条目在一个单独的因子上有很高的载荷（>0.75）。最终的五个条目子量表显示出良好的结构效度和效标效度、高内部一致性（Cronbach's α = 0.93）和重测信度（ICC = 0.67，p < 0.01）。
