Film-Based Medical Education and Social Justice Course: Effects on Alexithymia and Empathy in Medical Students

This is a prospective, nonrandomized controlled pretest-posttest study conducted at Canakkale Onsekiz Mart University Faculty of Medicine. Participants are volunteer medical students (≥18 years). The intervention group consists of students who enroll in the elective course, and the comparison group consists of students from the same student population who do not enroll during the same period.

Data will be collected at two time points: baseline prior to the start of the elective period (T0) and immediately after the end of the elective period (T1, approximately 14 weeks later). At each time point, participants will complete the study instruments administered in a standardized manner. In the intervention group, reflective journals will also be collected throughout the course period to support qualitative interpretation of findings.

The primary analysis will compare within-group change from T0 to T1 and between-group differences in change scores. Descriptive statistics will summarize participant characteristics. Depending on data distribution, paired tests and independent-group tests (or their nonparametric equivalents) will be used for continuous outcomes. Multivariable models may be used to adjust for baseline differences (e.g., class year) if imbalance is observed. Missing data will be handled using a predefined approach (e.g., complete-case analysis with sensitivity checks). No clinical procedures or medical treatments are involved.

Inclusion criteria

• Enrolled medical student at Canakkale Onsekiz Mart University Faculty of Medicine, registered in Year 1, 2, or 3 during the study period.
• Age 18 years or older.
• Provides written/electronic informed consent after being informed about the study.
• For the intervention arm: enrolled in the elective "Film-Based Medical Education and Social Justice" course.
• For the control arm: from the same academic year/cohort during the same period and not enrolled in the elective course.

• Younger than 18 years.
• Does not complete at least one of the two assessments (T0 or T1).
