Purpose
Professional identity (PI) formation occurs over time through immersive social—digital and in-person—interactions. While digital social interactions may support the PI formation of medical students, their influence remains underexplored. This study aimed to describe the patterns and intensity of social media use and analyze its association with PI.
Methods
This quantitative cross-sectional study was conducted at a private medical school in Jakarta, Indonesia. All undergraduate medical students were invited to participate in this study. Data were collected using the Social Networking Activity Intensity Scale (SNAIS) and the MacLeod Clark Professional Identity Scale (MCPIS-9) questionnaire. Data were analyzed descriptively and statistically.
Results
A total of 451 students participated in this study. Participants reported moderate overall social media use intensity (mean SNAIS=2.96±0.51), with higher use for entertainment than social interaction. The mean MCPIS-9 score was 3.76±0.44. Content engagement, measured using a content engagement index (CEI) reflecting the intensity of engagement with educational and informational content across selected social media activities, was generally low and driven mainly by browsing behaviors (CEI=0.51±0.64). Weak but significant correlations were observed between CEI and MCPIS-9 (ρ=0.139, p=0.003) and between SNAIS and MCPIS-9 (r=0.102, p=0.030). One-way analysis of variance revealed significant differences in MCPIS-9 scores by duration of use for WhatsApp and X, but not for other platforms.
Conclusion
Participants mainly used social media for entertainment purposes. Social media use intensity and content engagement showed weak but significant associations with PI.

Purpose
Addressing health inequities is an integral part of contemporary medical education (ME), yet traditional lecture-based formats often fail to develop students’ deeper understanding and engagement. This study examined how a project-based learning (PjBL) approach influenced students’ learning experiences related to health equity.
Methods
This was a qualitative phenomenology study. We designed an elective course on health equity using the PjBL approach and active learning methods. All participating students were asked to complete a group project aimed at addressing a specific health inequity issue from the surrounding community. Data were collected through reflective writing at the end of the course and analyzed using deductive thematic analysis. Twenty-seven codings were identified from 259 meaningful quotes (interrater agreement 99.62%) and grouped into four categories: character, role, competence, and learning experience.
Results
Three major themes emerged from data analysis: (1) key learning experiences during the ME course (active learning, role-modeling, collaborative learning, comprehensive learning, and affective learning); (2) topics that facilitated students’ understanding of health inequities and physicians’ roles, particularly in addressing health inequities in Indonesia; and (3) the influence of the ME course on students’ outlook and beliefs.
Conclusion
Although this study did not introduce a novel method of instruction, it underscores the value of PjBL in enhancing students’ capacity to understand and tackle health inequities.
