Abstract

Introduction: Toxoplasmosis is a major public health concern, especially in pregnant women, due to the risk of maternal–fetal transmission.Serodiagnosis, although essential, remains challenging for medical biology residents.
Objective: To evaluate the impact of an educational video on knowledge acquisition and learner perception regarding the serodiagnosis of toxoplasmosis in pregnant women.
Methods: An observational study was conducted at the Faculty of Medicine of Tunis (May–September 2025), including medical biology residents. Participants completed a pre-test, watched an educational video, and then completed a post-test and a qualitative evaluation. Pre-and post-test means were compared using a paired Student’s t-test, and the correlation between knowledge gain and satisfaction was assessed with Pearson’s coefficient.
Results: Sixty-four residents participated (mean age: 28.5 years; sex ratio = 0.08). Mean scores increased from 12.28 ± 4.0 (pre-test) to 15.41 ± 3.5 (post-test) (p < 0.001), reflecting a significant knowledge gain, with 52% scoring ≥16/20 post-intervention. Overall satisfaction was high: 91% found the video clear and relevant, and 97% would recommend it to colleagues. The correlation between score gain and satisfaction was
weak and not significant (r = 0.16; p = 0.26).
Conclusion: The educational video is an effective and highly appreciated tool for teaching the serodiagnosis of toxoplasmosis, facilitating the understanding and interpretation of complex serological profiles.
