Abstract

Background: Falls cause significant morbidity/mortality in older adults. Current scales assess fear of falling and proactive balance confidence but neglect confidence in reactive balance recovery (regaining stability after perturbations). The Balance Recovery Confidence Scale (BRCS) fills this gap, requiring cultural adaptation for Turkish populations.

Objective: To translate, culturally adapt, and validate the BRCS in community-dwelling Turkish older adults.

Methods: Following Beaton's guidelines, BRCS underwent forward-backward translation, expert review (n = 10), and pilot testing (n = 30). Psychometric validation included 76 adults ≥65 years. Content validity used Content Validity Index (CVI) and Ratio (CVR). Construct validity employed Exploratory/Confirmatory Factor Analysis (EFA/CFA). Reliability was assessed via Cronbach's α and Intraclass Correlation Coefficient (ICC₃,₁; 7-day retest). Convergent validity examined Spearman correlations between Turkish BRCS and Falls Efficacy Scale-International (FES-I), Activities-specific Balance Confidence Scale (ABC), Tinetti Balance & Gait Test (TBT&TGT), Timed Up and Go Test (TUG), 30-Second Chair Stand Test (30s-CST), and Handgrip Strength Test (HGST).

Results: Content validity was excellent (mean CVI = 0.92, CVR = 0.70-1.00). EFA/CFA confirmed a one-factor structure with excellent fit (CFI = 0.96, RMSEA = 0.045). Internal consistency (α = 0.94) and test-retest reliability (ICC₃,₁ = 0.94) were excellent. Turkish BRCS correlated strongly negatively with FES-I (-0.68), strongly positively with ABC (0.74), and moderately with physical performance tests (all p < .05). Standard Error of Measurement (SEM) = 6.91; Minimal Detectable Change at the 95% confidence level (MDC₉₅) = 19.16.

Conclusion: The Turkish BRCS is a valid, reliable tool for assessing reactive balance recovery confidence in older adults, suitable for clinical and research applications.

土耳其老年人平衡恢复信心量表的文化适应和心理计量学验证。

背景：老年人跌倒导致显著的发病率/死亡率。目前的量表评估了对摔倒的恐惧和主动平衡信心，但忽视了对反应性平衡恢复的信心（在扰动后恢复稳定）。平衡恢复信心量表（BRCS）填补了这一空白，要求土耳其人口适应文化。目的：在土耳其社区居住的老年人中翻译、文化适应和验证BRCS。方法：按照Beaton的指南，对BRCS进行前向后翻译、专家评审（n = 10）和试点测试（n = 30）。心理测量验证包括76名年龄≥65岁的成年人。内容效度采用Content validity Index （CVI）和Ratio （CVR）。构念效度采用探索性/验证性因子分析（EFA/CFA）。通过Cronbach’s α和类内相关系数（ICC₃，₁；7天重测）评估信度。收敛效度检验了土耳其BRCS与国际跌倒效能量表（FES-I）、特定活动平衡信心量表（ABC）、Tinetti平衡与步态测试（TBT&TGT）、计时起身测试（TUG）、30秒站立椅测试（30s-CST）和握力测试（HGST）之间的Spearman相关性。结果：内容效度极佳（平均CVI = 0.92, CVR = 0.70-1.00）。EFA/CFA证实单因素结构拟合良好（CFI = 0.96, RMSEA = 0.045）。内部一致性（α = 0.94）和重测信度（ICC₃，₁= 0.94）都很好。土耳其BRCS与FES-I呈显著负相关（-0.68），与ABC呈显著正相关（0.74），与体能测试呈正相关（均p）。结论：土耳其BRCS是评估老年人反应性平衡恢复信心的有效、可靠的工具，适用于临床和研究应用。

期刊介绍： The aim of Physiotherapy Theory and Practice is to provide an international, peer-reviewed forum for the publication, dissemination, and discussion of recent developments and current research in physiotherapy/physical therapy. The journal accepts original quantitative and qualitative research reports, theoretical papers, systematic literature reviews, clinical case reports, and technical clinical notes. Physiotherapy Theory and Practice; promotes post-basic education through reports, reviews, and updates on all aspects of physiotherapy and specialties relating to clinical physiotherapy.
