身份，或人们如何选择定义自己，正在成为一个有吸引力的解释谁坚持在工程。许多工程身份的研究建立在数学和科学身份的先前工作，强调工程的学术方面。然而，对专业实践的影响也是工程身份发展的核心。本文介绍了用于创建一个新的调查措施的个人对工程实践元素的影响的方法。我们遵循项目生成，细化和工具验证步骤所需的心理测量验证的一个新的调查措施。我们产生的项目演绎使用的文献工程专业技能和实践和归纳的基础上，与执业工程师，工程研究生和工程本科生的采访。我们混合了归纳和演绎导出的项目列表，以创建度量的初始项目列表。我们将这份物品清单分发给一组工程和专业身份专家，以建立表面有效性，并根据他们的反馈进行修改。最后的清单包括34个项目。这34个项目是在2016年秋季对两所院校三个专业的1465名工科本科生进行的问卷调查中进行的。我们进行了探索性因素分析（EFA），并建立了内部一致性，使用克朗巴赫的α分析样本数据的一个子集（n=384）。由此产生的因素符合我们对理论上表征对工程专业实践影响的因素的先验假设。使用剩余的数据（n=904），我们进行了验证性因素分析减少了一套项目，从全民教育。结果表明，一个新兴的因素结构，对工程实践要素的影响。
Identity, or how people choose to define themselves, is emerging as an attractive explanation for who persists in engineering. Many studies of engineering identity build off of prior work in math and science identity, emphasizing the academic aspects of engineering. However, affect towards professional practice is also central to engineering identity development. This paper describes the methods used to create a new survey measure of individuals’ affect toward elements of engineering practice. We followed the item generation, refinement, and instrument validation steps required for psychometric validation of a new survey measure. We generated items deductively using the literature on engineering professional skills and practice and inductively based on interviews with practicing engineers, engineering graduate students, and engineering undergraduate students. We blended the inductively and deductively derived item lists to create a list of initial items for the measure. We circulated this list of items to a set of engineering and professional identity experts to establish face validity and made modifications based on their feedback. The final list included 34 items. These 34 items were administered in a questionnaire survey in the fall of 2016 to 1465 engineering undergraduates in three majors at two institutions. We conducted an exploratory factor analysis (EFA) and established internal consistency using Cronbach’s alpha on a subset of the analytical sample data (n=384). The resulting factors fit our a priori assumption of the factors theorized to characterize affect towards engineering professional practice. Using the remaining data (n=904), we conducted a confirmatory factor analysis on the reduced set of items resulting from EFA. The results indicate an emergent factor structure for affect towards elements of engineering practice.
