简要总结
The aim of this study was to translate and culturally adapt the Pain Behaviour Scale (PaBS) into Turkish and to evaluate its psychometric properties in adults with chronic nonspecific low back pain. Specifically, the study examined interrater reliability, intrarater reliability, agreement, measurement error, and construct validity of the Turkish version of the PaBS during standardized functional performance tasks.
详细描述
The Pain Behaviour Scale (PaBS) is a clinician-rated observational measure designed to assess the presence and severity of pain behaviors during functional movement in individuals with chronic low back pain. Before its use in Turkish-speaking populations, translation, cross-cultural adaptation, and psychometric evaluation were required.
In this cross-cultural adaptation and psychometric validation study, the PaBS was translated into Turkish, back-translated, reviewed by an expert panel, and pilot-tested before the main psychometric evaluation. The prefinal Turkish version was pilot-tested in 20 adults with chronic nonspecific low back pain, and the pilot data were not included in the main analyses.
The main study included adults aged 18-55 years with chronic nonspecific low back pain lasting more than three months. Participants completed self-reported measures of pain, disability, and fear-avoidance beliefs and performed standardized physical performance tests. During the first testing session, two independent physiotherapists simultaneously rated pain behaviors using the Turkish PaBS. One rater repeated the PaBS assessment approximately one week later. The psychometric evaluation included interrater and intrarater reliability, agreement, measurement error, and construct validity.

研究组 & 干预措施
Adults With Chronic Nonspecific Low Back Pain
A total of 102 adults aged 18-55 years with chronic nonspecific low back pain lasting more than 3 months were included in the psychometric validation study. Participants underwent standardized clinical, self-report, and physical performance assessments during two testing sessions separated by approximately one week.

结局指标
主要结局
Turkish Pain Behaviour Scale (PaBS)
时间窗: Baseline and approximately 1 week
The Turkish Pain Behaviour Scale (PaBS) is a clinician-rated observational measure used to assess the presence and severity of pain behaviors during five standardized physical performance tests. Observed behaviors include sighing, breath-holding, grimacing, guarding, rubbing, and antalgic gait. For each physical performance test, the presence or absence of individual behaviors is recorded and the overall severity of observed pain behavior is rated from 0 to 3. The total PaBS severity score ranges from 0 to 15, with higher scores indicating greater severity of observed pain behaviors. Interrater reliability was evaluated using ratings from two independent raters during the first testing session, and intrarater reliability was evaluated using ratings from the same rater across two testing sessions.
