Professionalism is a critical part of a medical education, and various activities have been proposed to enhance professionalism among medical students. Watching films is an activity to promote character related to professionalism. Limitation of such is a single group pre-posttest design raising concerns about the errors of measurement. The study aimed to demonstrate a method to deal with this design using Rasch analysis.
This study used a pre-posttest design with 40 first year medical students. All participated in a 3-day activity that involved watching four selected movies: Twilight, Gandhi, The Shawshank Redemption and Amélie. These films offer compelling illustrations of the themes of self-regulation, humility, prudence and gratitude, respectively. All participants completed a 10-item composite scale (PHuSeG) addressing these themes before and after watching the movies. When determining who benefitted from the intervention, paired t-tests on the results of a Rasch analysis were used to evaluate changes between pre- and posttest. Using Rasch analyses, we could document the stability of the items from pre- to posttest, and significant changes at both the individual and group levels, which is a useful and practical approach for pre- and posttest design. Moreover, it helps validate the psychometric property of the instrument used.
职业素养是医学教育的关键部分，人们提出了各种活动来提高医学生的职业素养。观看电影是一种培养与职业素养相关品质的活动。其局限性在于采用单组前后测设计，这引发了对测量误差的担忧。本研究旨在展示一种使用拉施分析来处理这种设计的方法。
本研究采用前后测设计，纳入了40名一年级医学生。所有人都参加了一项为期3天的活动，该活动包括观看四部选定的电影：《暮光之城》《甘地传》《肖申克的救赎》和《天使爱美丽》。这些电影分别有力地展现了自我约束、谦逊、审慎和感恩的主题。所有参与者在观看电影前后都完成了一份针对这些主题的包含10个条目的综合量表（PHuSeG）。在确定谁从干预中受益时，使用基于拉施分析结果的配对t检验来评估前后测之间的变化。通过拉施分析，我们能够记录从测试前到测试后条目的稳定性，以及个体和群体层面的显著变化，这对于前后测设计来说是一种有用且实用的方法。此外，它有助于验证所使用工具的心理测量特性。
