Abstract: Objectives We assessed the reliability and validity of the Korean version of the Pain-related Beliefs and Attitudes about Sleep (PBAS) scale among patients with chronic pain. Furthermore, we investigated whether pan-related dysfunctional beliefs about sleep mediate the relationship between sleep severity and pain.Methods Overall, 100 participants with chronic pain were recruited using an anonymous online survey. Their demographic data and responses to pain severity rating scales, comprising the translated Korean version of the PBAS; Dysfunctional Beliefs and Attitudes about Sleep-16 (DBAS-16); Metacognition Questionnaire-Insomnia-6 (MCQI-6); and the Insomnia Severity Index (ISI), were collected.Results The Korean version of the PBAS scale has two-factor structure. The PBAS was a reliable scale which can measure pain-related dysfunctional beliefs about sleep among patients with chronic pain. It showed strong convergent validity with pain severity (r = 0.61, p < .001), DBAS-16 (r = 0.65, p < .001), MCQI-6 (r = 0.56, p < .001), and ISI (r = 0.68, p < .001) scores. Mediation analysis indicated that pain severity directly influenced insomnia severity, with PBAS, DBAS-16, and MCQI-6 scores partially mediating this association. Conversely, insomnia severity was associated with pain severity, with the PBAS score alone mediating this relationship.Conclusions The Korean PBAS is a reliable and valid rating scale which measures pain-specific, sleep-related dysfunctional beliefs among patients with chronic pain.
