Self-efficacy has become the target outcome of many self-management interventions for cancer survivors. However, no measurement is available that can be used to measure cancer-specific self-efficacy in Korea.
The aim of this study was to cross-culturally evaluate the reliability and validity of a Korean version of the Cancer Survivors' Self-Efficacy Scale (CSSES-K).
We translated the original version of the CSSES (11 items) and created a Korean version. We then conducted a validation study with 204 cancer survivors who had completed their primary treatment. We conducted psychometric evaluation using item analysis, factorial construct validity (exploratory factor analysis and confirmative factor analysis), hypothesis testing construct validity, and internal consistency reliability (Cronbach's α).
Exploratory factor analysis revealed 2 subscales for which model fitting was appropriate-"self-efficacy for managing health problems" (5 items) and "self-efficacy for seeking help and support" (5 items). Hypothesis testing construct validity was confirmed showing significant moderate correlations between the CSSES-K and general self-efficacy (r = 0.511, P < .001), anxiety (r = -0.596, P < .001), depression (r = -0.554, P < .001), and health-related quality of life (r = 0.586, P < .001). The internal consistency of the CSSES-K of total scale and subscales was high (Cronbach's α = .86-.92).
The results supported that the CSSES-K was valid and reliable in measuring self-efficacy among Korean cancer survivors after cancer treatment.
Our findings suggest that the CSSES-K can be effectively used for measuring self-efficacy in Korean cancer survivors.
自我效能已成为许多癌症幸存者自我管理干预的目标结果。然而，在韩国，还没有可用的测量工具来衡量癌症特定的自我效能。
本研究旨在跨文化评估韩国版癌症幸存者自我效能量表（CSSES-K）的信度和效度。
我们翻译了原始版 CSSES（共 11 个项目）并创建了韩文版。然后，我们对 204 名已完成主要治疗的癌症幸存者进行了验证研究。我们通过项目分析、因子结构有效性（探索性因子分析和验证性因子分析）、假设检验结构有效性和内部一致性可靠性（Cronbach's α）进行心理测量评估。
探索性因子分析显示出 2 个亚量表，其模型拟合情况良好，分别为“管理健康问题的自我效能”（5 个项目）和“寻求帮助和支持的自我效能”（5 个项目）。假设检验结构有效性得到证实，CSSES-K 与一般自我效能（r = 0.511，P <.001）、焦虑（r = -0.596，P <.001）、抑郁（r = -0.554，P <.001）和健康相关生活质量（r = 0.586，P <.001）之间存在显著的中度相关性。CSSES-K 总量表和各分量表的内部一致性均较高（Cronbach's α =.86-.92）。
结果表明，CSSES-K 在测量韩国癌症幸存者癌症治疗后自我效能方面是有效和可靠的。
我们的研究结果表明，CSSES-K 可有效用于测量韩国癌症幸存者的自我效能。
