Abstract

BACKGROUND

The Job Content Questionnaire (M-JCQ) is an established self-reported instrument used across the world to measure the work dimensions based on the Karasek's demand-control-support model.

OBJECTIVE

To evaluate the psychometrics properties of the Malay version of M-JCQ among nurses in Malaysia.

METHODS

This cross-sectional study was carried out on nurses working in 4 public hospitals in Klang Valley area, Malaysia. M-JCQ was used to assess the perceived psychosocial stressors and physical demands of nurses at their workplaces. Construct validity of the questionnaire was examined using exploratory factor analysis (EFA). Cronbach's α values were used to estimate the reliability (internal consistency) of the M-JCQ.

RESULTS

EFA showed that 34 selected items were loaded in 4 factors. Except for psychological job demand (Cronbach's α 0.51), the remaining 3 α values for 3 subscales (job control, social support, and physical demand) were greater than 0.70, indicating acceptable internal consistency. However, an item was excluded due to poor item-total correlation (r<0.3). The final M-JCQ was consisted of 33 items.

CONCLUSION

The M-JCQ is a reliable and valid instrument to measure psychosocial and physical stressors in the workplace of public hospital nurses in Malaysia.

摘要

背景

工作内容问卷（M-JCQ）是一种已确立的自我报告工具，在全球范围内用于根据 Karasek 的需求-控制-支持模型来衡量工作维度。

目的

评估马来西亚护士中 M-JCQ 马来语版本的心理测量学特性。

方法

这项横断面研究在马来西亚巴生谷地区的 4 家公立医院工作的护士中进行。使用 M-JCQ 评估护士在工作场所感受到的心理社会压力源和身体需求。使用探索性因素分析（EFA）检验问卷的结构效度。Cronbach's α 值用于估计 M-JCQ 的信度（内部一致性）。

结果

探索性因素分析表明，34 个选定项目加载到 4 个因素中。除心理工作需求（Cronbach's α 为 0.51）外，3 个分量表（工作控制、社会支持和身体需求）的其余 3 个 α 值均大于 0.70，表明内部一致性可接受。然而，由于项目与总分的相关性较差（r<0.3），排除了一个项目。最终的 M-JCQ 由 33 个项目组成。
