To determine the psychometric properties of the modified Care Dependency Scale for Rehabilitation.
All patients were assessed independently by a different set of two randomly selected nurses.
A convenience sample consisting of 1197 patients and 42 nurses was recruited in an Austrian rehabilitation centre specialized on the treatment and care of neurological and orthopaedic patients.
The Care Dependency Scale for Rehabilitation and the Barthel Index.
To estimate aspects of reliability, Cronbach's alpha, Cohen's kappa, percentage agreement, intraclass correlation coefficient (ICC) and standard error of measurement (SEM) were calculated. To evaluate the construct validity, a factor analysis was conducted. Criterion-related validity was examined by comparing data of the modified Care Dependency Scale for Rehabilitation with the Barthel Index and Pearson calculation.
The calculation of Cronbach's alpha yielded values of 0.97. Kappa values were between 0.89 and 0.96, values of percentage agreement between 96% and 99%, ICC values between 0.94 and 0.99, and SEM values between 0.08 and 0.17. Pearson (r) was 0.88. The factor analysis revealed a one-factor solution.
The modified Care Dependency Scale for Rehabilitation shows a high internal consistency, as well as a high level of equivalence. Furthermore, criterion-related validity and construct validity have shown satisfying results.
确定改良康复护理依赖量表的心理计量特性。
所有患者均由两组随机选择的护士独立评估。
在一家专门治疗神经和骨科患者的奥地利康复中心，招募了 1197 名患者和 42 名护士组成的便利样本。
康复护理依赖量表和巴氏指数。
为了评估可靠性，计算了 Cronbach's alpha、Cohen's kappa、百分比一致性、组内相关系数（ICC）和测量标准误差（SEM）。为了评估结构效度，进行了因子分析。通过将改良康复护理依赖量表的数据与巴氏指数和 Pearson 计算进行比较，评估了效标关联效度。
Cronbach's alpha 的计算值为 0.97。kappa 值在 0.89 到 0.96 之间，百分比一致性值在 96%到 99%之间，ICC 值在 0.94 到 0.99 之间，SEM 值在 0.08 到 0.17 之间。Pearson(r)为 0.88。因子分析显示出一个单因素解决方案。
改良康复护理依赖量表具有较高的内部一致性和等效性。此外，效标关联效度和结构效度也取得了令人满意的结果。
