BACKGROUND
The Exercise Adherence Rating Scale (EARS) is a commonly used outcome tool, which helps to identify the adherence rate of exercises and reasons for adherence and non-adherence. There is no evidence of the availability of any measurement tools to assess exercise adherence in the Nepalese context and cultural background. Therefore, we conducted a cross-cultural adaptation of the EARS into the Nepali language and investigated its reliability and validity.
METHODS
Cross-cultural adaptation of the EARS was done based on Beaton guidelines. Psychometric properties were evaluated among 18 participants aged 18 years or older with pre-diabetes or confirmed diagnosis of any disease who were prescribed with home exercises by physiotherapists. Any disease that limited participants from doing exercise and individuals unwilling to participate were excluded. Reliability was evaluated through internal consistency, using Cronbach's alpha. Exploratory Factor Analysis (EFA) was performed to explore construct validity and confirm its unidimensionality. Receiver Operating Characteristic (ROC) curve was analyzed to identify cut-off score, sensitivity and specificity of the tool.
RESULTS
The Cronbach's alpha was 0.94 for EARS-adherence behavior. The EFA of 6-items adherence behavior revealed the presence of one factor with an eigenvalue exceeding one. The scree-plot suggested for extraction of only one factor with strong loading (75.84%). The Area Under the Curve was 0.91 with 95% confidence interval 0.77-1.00 at p = 0.004. The cutoff score was found 17.5 with 89% sensitivity and 78% specificity.
CONCLUSIONS
The EARS was cross-culturally adapted to the Nepali language. The reliability and construct validity of the Nepali version of the EARS were acceptable to assess exercise adherence in Nepali-speaking individuals. This validated tool might facilitate the evaluation of exercise-related interventions. Future studies could investigate other psychometric properties of the Nepali EARS.
背景
运动依从性评定量表（EARS）是一种常用的结局工具，有助于识别运动的依从率以及依从和不依从的原因。目前在尼泊尔的文化背景下，尚无评估运动依从性的测量工具。因此，我们对 EARS 进行了跨文化适应性改编，并对其信度和效度进行了研究。
方法
根据 Beaton 指南对 EARS 进行了跨文化适应性改编。在由物理治疗师开出家庭运动处方的 18 名年龄在 18 岁及以上的糖尿病前期或任何疾病确诊患者中评估了其心理测量学特性。排除了任何限制患者运动或不愿参与的疾病。通过 Cronbach's alpha 评估内部一致性来评估信度。通过探索性因子分析（EFA）来探讨结构效度并确认其单维性。分析接受者操作特征（ROC）曲线以确定工具的截止分数、敏感性和特异性。
结果
EARS-依从性行为的 Cronbach's alpha 为 0.94。6 项依从性行为的 EFA 显示存在一个特征值超过 1 的因子。陡坡图建议仅提取具有强负荷（75.84%）的一个因子。曲线下面积为 0.91，95%置信区间为 0.77-1.00，p=0.004。截距分数为 17.5，敏感性为 89%，特异性为 78%。
结论
EARS 已被跨文化改编为尼泊尔语。尼泊尔语版 EARS 的信度和结构效度可用于评估尼泊尔语人群的运动依从性。这种经过验证的工具可能有助于评估与运动相关的干预措施。未来的研究可以进一步调查尼泊尔 EARS 的其他心理测量学特性。
