This study aimed to investigate the differences in the Injustice Experience Questionnaire (IEQ) scores during the early period after the diagnosis of Whiplash-associated disorder (WAD) between Japanese and Canadian samples, and the associations between the IEQ scores and treatment terms in Japanese patients with acute WAD.
We used secondary data for the IEQ scores of Canadian patients with acute WAD. In Japan, we collected data from 85 consecutively enrolled patients with acute WAD, and their treatment terms were collected; these referred to the number of days between the date of injury and the closure date of the insurance claim and the number of treatment visits. Before treatment, the Numeric Rating Scale, Neck Disability Index, Hospital Anxiety and Depression Scale, IEQ, and Euro Quality of Life five-dimensional questionnaire were administered. The variables were subjected to multivariate analysis with each treatment term.
The IEQ scores were higher in Japan than in Canada. Through multiple regression analysis, IEQ scores were independently correlated with treatment terms. The optimal cutoff point of the IEQ scores for a prolonged treatment term was 21 and 22 points, respectively.
The IEQ scores were associated with treatment terms in patients with acute WAD in Japan.
本研究旨在调查日本和加拿大样本在诊断为挥鞭样损伤相关障碍（WAD）后的早期阶段，在不公正体验问卷（IEQ）评分方面的差异，以及IEQ 评分与日本急性 WAD 患者治疗条件之间的相关性。
我们使用加拿大急性 WAD 患者的 IEQ 评分的二次数据。在日本，我们连续收集了 85 例急性 WAD 患者的数据，并收集了他们的治疗条件，即受伤日期和保险索赔截止日期之间的天数以及治疗就诊次数。在治疗前，对患者进行数字评分量表、颈部残疾指数、医院焦虑抑郁量表、IEQ 和欧洲生活质量五维度问卷评估。对这些变量与每个治疗条件进行多元回归分析。
IEQ 评分在日本高于加拿大。通过多元回归分析，IEQ 评分与治疗条件独立相关。IEQ 评分延长治疗时间的最佳截断值分别为 21 分和 22 分。
IEQ 评分与日本急性 WAD 患者的治疗条件相关。
