Major decision-making self-efficacy (MDMSE) is an important indicator of students' ability to make effective decisions in specialty selection. It has implications for students' personal growth and career counselling interventions. While the previous MDMSES has been widely used in the context of China's New College Entrance Examination reform, the increased choice of majors and advancement of career planning necessitate a new scale to assess high school students' MDMSE levels.
Scale items were generated based on a literature review, student interviews, and expert reviews. Exploratory Factor Analysis and Confirmatory Factor Analysis were used to assess the appropriateness of the scale's structure, and network analysis was used to calculate concurrent validity. Retest reliability was calculated to evaluate stability.
The MDMSES contains 24 items with five factors (Information Acquisition, Decision Persistence, Self-Determination, Self-Evaluation, and Social Support). The results show that the scale has a good five-factor structure (χ/df = 1.91, CFI = 0.92, TLI = 0.91, RMSEA = 0.05, and SRMR = 0.06), and the internal consistency reliability of the total scale is 0.91.
The scale development results satisfied the psychometric and statistical criteria, allowing the scale to be used as a means of detection to support intervention efforts for individuals with low MDMSE levels.
重大决策自我效能感（MDMSE）是学生在专业选择中做出有效决策能力的重要指标。它对学生的个人成长和职业咨询干预具有重要意义。尽管先前的MDMSES已在中国新高考改革背景下广泛使用，但专业选择的增加和职业规划的推进需要一个新的量表来评估高中生的MDMSE水平。
量表项目基于文献综述、学生访谈和专家评审生成。采用探索性因素分析和验证性因素分析来评估量表结构的适宜性，并使用网络分析来计算同时效度。计算重测信度以评估稳定性。
MDMSES包含24个项目，分为五个因素（信息获取、决策坚持性、自我决定、自我评估和社会支持）。结果表明，该量表具有良好的五因素结构（χ/df = 1.91，CFI = 0.92，TLI = 0.91，RMSEA = 0.05，SRMR = 0.06），总量表的内部一致性信度为0.91。
量表编制结果满足心理测量和统计学标准，该量表可作为一种检测手段，为MDMSE水平较低的个体的干预工作提供支持。
