Study design

Development and psychometrics study

Objective

To evaluate the reliability and validity of a new version of Appraisals of Post-Traumatic Spinal Cord Injury Health Scale (APTSCIHS) in the Persian language for persons with spinal cord injury (SCI).

Setting

The persons were selected from National Spinal Cord Injury Registry of Iran (NSCIR-IR) and Brain and Spinal Cord Injury Research center (BASIR).

Method

This was a mixed sequential exploratory study that performed in two phases. In the qualitative phase, a systematic scoping review and 12 interviews with the participants were done. Finally, items were generated. In the quantitative phase, face, content, construct and convergent validity were assessed to evaluate validity. To evaluate construct validity, a cross-sectional study was conducted on 305 persons with TSCI along with internal consistency and stability assessments. All quantitative data analyses were conducted using SPSS 22 software.

Results

The content validity and reliability were indicated by Scale’s Content Validity Ratio (S-CVR) = 0.73 and Scale’s Content Validity Index (S-CVI) = 0.86, Cronbach’s α = 0.9 and the Test re-test reliability using intra-class correlations were (ICC) = 0.97 to 0.98. Exploratory factor analysis determined eight factors which showed more than 52% of the variance. APTSCIHS had a significant and strong correlation with Appraisals of DisAbility Primary and Secondary Scale (ADAPSS) (r = 0.475, P < 0.001).

Conclusion

Results showed the 36 items APTSCIHS tool had an acceptable validity and reliability in Iran, and it can help health care providers or even administrators improve the quality of the rehabilitation services and quality of life.

伊朗创伤后脊髓损伤健康量表评估的开发和心理测量特性

学习规划

发展和心理测量研究

客观的

评估新版波斯语创伤后脊髓损伤健康评估量表 (APTSCIHS) 对脊髓损伤 (SCI) 患者的信度和效度。

环境

这些人员选自伊朗国家脊髓损伤登记处（NSCIR-IR）和脑和脊髓损伤研究中心（BASIR）。

方法

这是一项分两个阶段进行的混合序贯探索性研究。在定性阶段，对参与者进行了系统范围界定审查和 12 次访谈。最后，物品就生成了。在定量阶段，通过评估表面效度、内容效度、结构效度和收敛效度来评价效度。为了评估结构有效性，对 305 名 TSCI 患者进行了一项横断面研究，并进行了内部一致性和稳定性评估。所有定量数据分析均使用 SPSS 22 软件进行。

结果

内容效度和信度由量表内容效度比 (S-CVR) = 0.73 和量表内容效度指数 (S-CVI) = 0.86、Cronbach's α = 0.9 表示，使用组内相关性的测试重测信度为 (国际商会）= 0.97 至 0.98。探索性因素分析确定了 8 个因素，显示出超过 52% 的方差。 APTSCIHS 与初级和二级残疾评估量表 (ADAPSS) 具有显着且强的相关性 (r = 0.475，P  < 0.001)。

结论

结果显示，36个项目的APTSCIHS工具在伊朗具有可接受的效度和信度，可以帮助医疗保健提供者甚至管理人员提高康复服务质量和生活质量。
