The Index of Work Satisfaction (IWS) is a comprehensive scale assessing nurses' professional satisfaction. The aim of the present study was to explore: a) the applicability, reliability and validity of the Greek version of the IWS and b) contrasts among the factors addressed by IWS against the main themes emerging from a qualitative phenomenological investigation of nurses' professional experiences.
A descriptive correlational design was applied using a sample of 246 emergency and critical care nurses. Internal consistency and test-retest reliability were tested. Construct and content validity were assessed by factor analysis, and through qualitative phenomenological analysis with a purposive sample of 12 nurses. Scale factors were contrasted to qualitative themes to assure that IWS embraces all aspects of Greek nurses' professional satisfaction.
The internal consistency (α = 0.81) and test-retest (tau = 1, p < 0.0001) reliability were adequate. Following appropriate modifications, factor analysis confirmed the construct validity of the scale and subscales. The qualitative data partially clarified the low reliability of one subscale.
The Greek version of the IWS scale is supported for use in acute care. The mixed methods approach constitutes a powerful tool for transferring scales to different cultures and healthcare systems.
工作满意度指数（IWS）是一个评估护士职业满意度的综合量表。本研究的目的是探讨：a）IWS希腊语版本的适用性、信度和效度；b）IWS所涉及的因素与对护士职业经历进行定性现象学调查所产生的主要主题之间的对比。
采用描述性相关设计，样本为246名急诊和重症护理护士。测试了内部一致性和重测信度。通过因子分析以及对12名护士的目的抽样进行定性现象学分析，评估了结构效度和内容效度。将量表因素与定性主题进行对比，以确保IWS涵盖了希腊护士职业满意度的所有方面。
内部一致性（α = 0.81）和重测（tau = 1，p < 0.0001）信度良好。经过适当修改后，因子分析证实了该量表及其子量表的结构效度。定性数据部分解释了一个子量表信度较低的原因。
支持IWS量表的希腊语版本用于急性护理。混合方法是将量表应用于不同文化和医疗系统的有力工具。
