Professional identity has been linked to organizational outcomes such as job performance and commitment, as well as health and well-being indices such as burnout and depression. Professional identity is a powerful mechanism that can be affected by social and environmental factors. It is therefore important to establish a reliable and valid measurement of professional identity that is useful in different contexts. The current study examines the psychometric properties of Brown's Professional Identification Scale (PIS) using three different but complementary approaches: classical test theory, Mokken analysis, and Rasch analysis. The study participants ( = 355), school teachers recruited from all over South Africa, completed the PIS, the Satisfaction with Life Scale, and the Teacher Satisfaction Scale. The reliability and validity of a reduced 8-item version of the PIS was confirmed. Mokken and Rasch analyses indicated that the scale consists of more than one dimension, and classical test theory (exploratory and confirmatory factor analysis) supported a two-factor structure. Ancillary bifactor indices indicated that professional pride and professional discontent explained a sufficient amount of the variance over and above that explained by the professional identity as a total scale. Overall, the findings support an 8-item PIS for use in a South African teacher population.
职业认同与工作绩效和敬业度等组织成果以及职业倦怠和抑郁等健康与幸福指标相关联。职业认同是一种强大的机制，会受到社会和环境因素的影响。因此，建立一种在不同情境下都有用的可靠且有效的职业认同测量方法很重要。本研究使用三种不同但互补的方法——经典测验理论、莫肯分析和拉施分析，检验了布朗职业认同量表（PIS）的心理测量特性。研究参与者（n = 355）是从南非各地招募的学校教师，他们完成了PIS、生活满意度量表和教师满意度量表。一个简化的8项版PIS的信度和效度得到了证实。莫肯分析和拉施分析表明该量表由多个维度组成，经典测验理论（探索性和验证性因素分析）支持双因素结构。辅助双因素指标表明，职业自豪感和职业不满在作为总量表的职业认同所解释的方差之外，还解释了足够多的方差。总体而言，研究结果支持在南非教师群体中使用8项版PIS。
