Abstract

BACKGROUND

Return to work (RTW) after injury or illness is a behavior influenced by physical, psychological and social factors. This study aims to determine the structural validity and reliability of a return to work assessment scale using internal consistency and factor analysis.

METHOD

A cross sectional survey research design was adopted for this study involving 101 Post stroke survivors. The return to work assessment scale, which was developed by Ibikunle et al. in 2019, was subjected to structural validity and reliability.

RESULT

The results reveal that 58 (57.4%) were males and 43 (42.2%) females with mean ages of 53.88±10.68 years. Internal consistency was high with a Cronbach's alpha coefficient of 0.81 for Domain 1, 0.93 for Domain 2 and 0.76 for Domain 3.Test-retest reliability analysis gave an ICC of 0.85(p = 0.001) for Domain 1, Domain 2 an ICC of 0.91 (p = 0.001) and Domain 3 an ICC of 0.99 (p = 0.001). The Kaiser-Meyer-Olkin measure of sampling adequacy (KMO) value for Domain 1 was X2 = 0.63 and that of Bartlett's test of sphericity value was significant (P = 0.000), Kaiser-Meyer-Olkin measure of sampling adequacy for Domain 2 was 0.84 and the Bartlett's test of sphericity value was significant (P = 0.000), the Kaiser-Meyer-Olkin measure of sampling adequacy for Domain 3 was 0.66 while the Barlett's test of sphericity was significant (p = 0.001). Therefore the factor analysis was appropriate.

CONCLUSION

The return to work assessment scale is a good, internally consistent and reliable tool that has demonstrated good group and structural validity.

摘要

背景

受伤或患病后的重返工作岗位（RTW）是一种受身体、心理和社会因素影响的行为。本研究旨在通过内部一致性和因子分析来确定重返工作评估量表的结构有效性和可靠性。

方法

本研究采用横断面调查研究设计，涉及 101 名脑卒中幸存者。 Ibikunle 等人于 2019 年开发的重返工作评估量表经过结构有效性和可靠性测试。

结果

结果显示，58 名（57.4%）为男性，43 名（42.2%）为女性，平均年龄为 53.88±10.68 岁。内部一致性较高，第 1 域的 Cronbach's alpha 系数为 0.81，第 2 域为 0.93，第 3 域为 0.76。重测信度分析得出第 1 域的 ICC 为 0.85（p=0.001），第 2 域的 ICC 为 0.91（p=0.001），第 3 域的 ICC 为 0.99（p=0.001）。第 1 域的 Kaiser-Meyer-Olkin 样本充足度量（KMO）值为 X2=0.63，Bartlett 球形检验值显著（P=0.000），第 2 域的 Kaiser-Meyer-Olkin 样本充足度量值为 0.84，Bartlett 球形检验值显著（P=0.000），第 3 域的 Kaiser-Meyer-Olkin 样本充足度量值为 0.66，Bartlett 球形检验值显著（p=0.001）。因此，因子分析是合适的。
