The study analyses medical students&#39; professional identity and the internal factors that influence it.<span style="font-family:"Times New Roman",serif"></span><br> <b>Material & Methods:</b> This cross-sectional study was conducted from January to March 2023. Total sampling was conducted on fourth-year academic level and second-year professional level students. Questionnaires were distributed via Google Form and only completed questionnaires were analyzed. Professional identity was measured using Tagawa&#39;s Development Scale.<span style="font-family:"Times New Roman",serif"></span><br> <b>Results:</b> The study was conducted at Hasanuddin University&#39;s Faculty of Medicine in Makassar, Indonesia. The total number of respondents was 492, consisting of 203 undergraduate and 288 second-year clerkship students. Students in both education levels showed positive results in self-control, awareness as a doctor, and reflection on the role of a doctor. However, social responsibility and self-external and self-internal internalization indicated lower scores. Age showed varying results for self-control, self-awareness as a doctor, and reflection on the role of a doctor. Living independently demonstrated differences only in the ability to self-externalize and self-internalize. The school of origin did not indicate significant differences for all development scale factors. At the same time, parent occupation exhibited distinct effects on self-control, awareness as a doctor, reflection on the role of a doctor, and social responsibility. Motivation showed differences only in the factor of self-control.<span style="font-family:"Times New Roman",serif"></span><br> <b>Conclusion:</b> Regarding self-control, self-awareness, and self-reflection, medical students&#39; professional identities are better developed at the professional than academic levels. Integrity, internalization of external and internal influences, and social responsibility components are still low and do not vary. Age, parents&#39; educational backgrounds, and reasons for enrolling in medical school influence professional identity formation.<span style="font-family:"Times New Roman",serif"></span></span></span></span> professional identity, development scale, medical student 1 9 http://edujournal.zums.ac.ir/browse.php?a_code=A-12-2269-1&slc_lang=en&sid=1 Deviana Soraya Riu Corresponding author’s Email: virayariu@gmail.com 5300319475328460033369 5300319475328460033369 Yes Department of Medical Education, Faculty of Medicine, Hasanuddin University, Makassar, Indonesia Haerani Rasyid haeraniabdurasyid@yahoo.com 5300319475328460033370 5300319475328460033370 No Department of Medical Education, Faculty of Medicine, Hasanuddin University, Makassar, Indonesia Agussalim Bukhari agussalim.bukhari@med.unhas.ac.id 5300319475328460033371 5300319475328460033371 No Department of Medical Education, Faculty of Medicine, Hasanuddin University, Makassar, Indonesia Irwin Aras irwinaras@gmail.com 5300319475328460033372 5300319475328460033372 No Department of Medical Education, Faculty of Medicine, Hasanuddin University, Makassar, Indonesia Asty Amalia Nurhadi mamanya.ali@yahoo.com 5300319475328460033373 5300319475328460033373 No Department of Medical Education, Faculty of Medicine, Hasanuddin University, Makassar, Indonesia Irawan Yusuf irawanyusufgenome@gmail.com 5300319475328460033374 5300319475328460033374 No Department of Medical Education, Faculty of Medicine, Hasanuddin University, Makassar, Indonesia Irfan Idris irfanfaal@gmail.com 5300319475328460033375 5300319475328460033375 No Department of Medical Education, Faculty of Medicine, Hasanuddin University, Makassar, Indonesia Andi Alfian Zainuddin dr.alfian@gmail.com 5300319475328460033376 5300319475328460033376 No Department of Medical Education, Faculty of Medicine, Hasanuddin University, Makassar, Indonesia
