BACKGROUND: The Sciatica Frequency Index (SFI) and Sciatica Bothersomeness Index (SBI) are two separate indices scored for both the bothersomeness and frequency of radiating symptoms. There is no Turkish scale used specifically for sciatica. OBJECTIVE: We aimed to translate SBI and SBI in Turkish and investigate the reliability and validity of these indices. METHODS: A total of 80 patients with lumbar disc herniation (LDH) were prospectively included. Construct validity was assessed by comparing the SBI and SFI with subscales of Short Form 36 (SF-36), back and leg Numeric Rating Scale (NRS) and Roland Morris Disability Questionnaire (RMDQ). Reliability was assessed by internal consistency (Cronbach’s alpha) and test-retest reliability. RESULTS: A weak correlation was found between SBI/SFI, back NRS and SF-36 subgroups while a moderate correlation was found between SBI/SFI, RMDQ and leg NRS. The SBI and SFI had high internal consistency measured by Cronbach’s alpha (0.76 and 0.73). Test-retest reliability of the SBI and SFI were 0.95 (95% CI: 0.92–0.97) and 0.95 (95% CI: 0.92–0.97) respectively, indicating excellent reliability. CONCLUSION: The Turkish versions of the SFI/SBI are a valid and reliable tool supporting their usability in patients with LDH-induced sciatica.

土耳其版本的坐骨神经痛烦恼度和坐骨神经痛频率指数的可靠性和有效性

背景：坐骨神经痛频率指数 (SFI) 和坐骨神经痛烦扰指数 (SBI) 是针对放射症状的烦扰性和频率评分的两个独立指数。没有专门用于坐骨神经痛的土耳其秤。目标：我们旨在将 SBI 和 SBI 翻译成土耳其语，并调查这些指数的可靠性和有效性。方法：前瞻性纳入 80 例腰椎间盘突出症 (LDH) 患者。通过将 SBI 和 SFI 与短表 36 (SF-36)、背部和腿部数字评定量表 (NRS) 和罗兰莫里斯残疾问卷 (RMDQ) 的子量表进行比较来评估结构有效性。可靠性通过内部一致性（Cronbach's alpha）和重测信度进行评估。结果：SBI/SFI 之间存在弱相关性，后 NRS 和 SF-36 亚组，而 SBI/SFI、RMDQ 和腿部 NRS 之间存在中等相关性。SBI 和 SFI 具有较高的内部一致性，由 Cronbach 的 alpha（0.76 和 0.73）衡量。SBI 和 SFI 的重测信度分别为 0.95（95% CI：0.92-0.97）和 0.95（95% CI：0.92-0.97），表明信度极佳。结论：土耳其语版本的 SFI/SBI 是一种有效且可靠的工具，支持其在 LDH 诱发的坐骨神经痛患者中的可用性。
