Background/Aims: Currently, no validated method exists to assess possible pain catastrophizing in adolescents with FMF. Thus, the objective of this study was to determine the validity and reliability of the Turkish Pain Catastrophizing Scale-Child (PCS-C) in adolescents with FMF by investigating internal consistency, test-retest reliability, and convergent validity. Materials and Methods: Turkish PCS-C, Visual Analog Scale during rest (VAS-rest) and activity (VAS-activity), and Pediatric Quality of Life Inventory (PedsQL) Arthritis Module 3.0 were administered to 66 adolescents with FMF (age: 13-18 years). Cronbach's alpha value was calculated for internal consistency. Turkish PCS-C was re-administered 2 weeks later by phone to 24 participants to calculate intraclass correlation coefficients (ICCs) for determining test-retest reliability. Convergent validity was investigated by calculating Spearman's Rank Correlation Coefficients (rs) between Turkish PCS-C and other evaluated parameters. Results: Item 8 was excluded from the Turkish PCS-C due to its low contribution to internal consistency. Following this, the Cronbach's alpha was calculated as 0.934. The remaining items contributed to the total score (item-total correlations > 0.4), and Cronbach's alpha did not differ significantly with the exclusion of any items (change < 1%). The Turkish PCS-C demonstrated excellent test-retest reliability (ICC = 0.925). Fair to moderate positive correlations were detected between the Turkish PCS-C total score and VAS-rest (rs = 0.373), VAS-activity (rs = 0.536), and PedsQL scores (rs = 0.551). Conclusion: Turkish PCS-C may be used as a valid and reliable tool to assess pain catastrophizing in adolescents with FMF.· Unpredictable nature of the pain in FMF may cause pain catastrophizing. · The validity and reliability of Turkish Pain Catastrophizing Scale-Child (PCS-C) was shown for the first time in an adolescent age group. · Turkish PCS-C was introduced to clinical and research settings to evaluate the possible pain catastrophizing in FMF.
背景/目的：目前，尚无经过验证的方法来评估家族性地中海热（FMF）青少年可能存在的疼痛灾难化情况。因此，本研究的目的是通过调查内部一致性、重测信度和收敛效度，确定土耳其儿童疼痛灾难化量表（PCS-C）在FMF青少年中的效度和信度。材料与方法：对66名FMF青少年（年龄：13 - 18岁）进行土耳其语PCS-C、静息视觉模拟量表（VAS-rest）和活动视觉模拟量表（VAS-activity）以及儿童生活质量量表（PedsQL）关节炎模块3.0的测评。计算Cronbach's alpha值以评估内部一致性。两周后通过电话对24名参与者再次进行土耳其语PCS-C测评，计算组内相关系数（ICC）以确定重测信度。通过计算土耳其语PCS-C与其他评估参数之间的斯皮尔曼等级相关系数（rs）来研究收敛效度。结果：由于第8项对内部一致性的贡献较低，故将其从土耳其语PCS-C中排除。在此之后，计算出Cronbach's alpha为0.934。其余项目对总分有贡献（项目-总分相关>0.4），并且排除任何项目后Cronbach's alpha无显著差异（变化<1%）。土耳其语PCS-C表现出出色的重测信度（ICC = 0.925）。在土耳其语PCS-C总分与VAS-rest（rs = 0.373）、VAS-activity（rs = 0.536）和PedsQL评分（rs = 0.551）之间检测到中等程度的正相关。结论：土耳其语PCS-C可作为评估FMF青少年疼痛灾难化情况的有效且可靠的工具。· FMF疼痛的不可预测性可能导致疼痛灾难化。· 首次在青少年年龄组中显示了土耳其儿童疼痛灾难化量表（PCS-C）的效度和信度。· 将土耳其语PCS-C引入临床和研究环境以评估FMF中可能存在的疼痛灾难化情况。
