Refining Lodahl and Kejner’s Job Involvement Scale with a Convergent Evidence Approach: Applying Multiple Methods to Multiple Samples
用五种方法（内容分析、经典项目分析、项目反应理论、部分验证性因子分析和区分效度分析）检验了Lodahl和Kejner的工作投入量表，发现许多项目测量效果不佳，并提炼出一个更准确的精简版本。
Lodahl and Kejner’s Job Involvement (JI) measure has been and continues to be heavily used despite known measurement deficiencies. Using a convergent evidence approach, the authors examine the psychometric properties of that scale and offer a refined version that accurately taps the JI construct. Based on a combination of five methodologies (qualitative content analysis, classical item analyses, item response theory analyses, partial confirmatory factor analyses, and discriminant validity analysis) applied to five samples, results indicate that numerous items function inadequately as indicators of JI, whereas a core of items have superior item statistics and conceptually match the definition of JI. The advantages of using a convergent evidence approach are discussed.
