We explored the reliability and validity of the Pain-related Beliefs and Attitudes about Sleep (PBAS) scale among patients with cancer. Further, we compared the usability of the PBAS scale with that of the Cancer-related Dysfunctional Beliefs and Attitudes about Sleep-14 (C-DBAS-14) among patients with cancer.
The medical records of 252 patients with cancer who visited the Sleep Clinic from August 1, 2023 to June 30, 2024 were retrospectively analyzed. The responses of the enrolled patients to the PBAS, C-DBAS-14, Insomnia Severity Index (ISI), and Numeric Rating Scale of pain were collected.
The internal consistency reliability of the PBAS scale was excellent (Cronbach's alpha of 0.96). Confirmatory factor analysis showed that the two-factor structure of the PBAS for patients with cancer is a good fit for the model (CFI=0.99, TLI=0.99, RMSEA=0.14, SRMR=0.05). The convergent validity of the Korean version of the PBAS in patients with cancer was good, as indicated by its significant association with pain severity (r=0.63, p<0.001), C-DBAS-14 (r=0.33, p<0.001), and ISI (r=0.21, p<0.01). The PBAS adequately reflected an increase in pain severity and was more effective and appropriate for capturing pain-related dysfunctional sleep beliefs than the C-DBAS-14.
The Korean version of the PBAS showed high reliability and validity in patients with cancer, and applicability across cancer types and cancer-related beliefs.
我们探讨了癌症患者中疼痛相关睡眠信念与态度量表（PBAS）的信度和效度。此外，我们比较了PBAS量表与癌症相关睡眠功能失调信念与态度量表-14（C-DBAS-14）在癌症患者中的可用性。
回顾性分析了2023年8月1日至2024年6月30日期间到睡眠诊所就诊的252例癌症患者的病历。收集了入组患者对PBAS、C-DBAS-14、失眠严重程度指数（ISI）和疼痛数字评定量表的回答。
PBAS量表的内部一致性信度极佳（Cronbach's α为0.96）。验证性因素分析表明，癌症患者PBAS的双因素结构与模型拟合良好（CFI = 0.99，TLI = 0.99，RMSEA = 0.14，SRMR = 0.05）。癌症患者中韩文版PBAS的收敛效度良好，这体现在它与疼痛严重程度（r = 0.63，p < 0.001）、C-DBAS-14（r = 0.33，p < 0.001）和ISI（r = 0.21，p < 0.01）显著相关。PBAS充分反映了疼痛严重程度的增加，并且在捕捉与疼痛相关的功能失调睡眠信念方面比C-DBAS-14更有效、更合适。
韩文版PBAS在癌症患者中显示出高信度和效度，并且适用于各种癌症类型和癌症相关信念。
