BackgroundTraumatic Brain Injury (TBI) remains a significant problem in certain regions of the world but receives little attention despite its enormous burden. This discrepancy could consequently lead to various misconceptions among the general public. This study evaluated misconceptions about TBI in five African countries. MethodsData for this cross-sectional study were collected using the Common Misconception about Traumatic Brain Injury (CM-TBI) questionnaire, which was electronically disseminated from January 16 to February 6, 2021. Associations between the percentage of correct answers and independent variables (i.e., sociodemographic characteristics and experience with TBI) were evaluated with the ANOVA test. Additionally, answers to the question items were compared against independent variables using the Chi-Square test. A P-value <0.05 was considered statistically significant. ResultsA total of 817 adults, 50.2% female (n=410), aged 24.3 ± 4.3 years, and majoritarily urban dwellers (94.6%, n=773) responded to the survey. They had received tertiary education (79.2%, n=647) and were from Nigeria (77.7%, n=635). Respondents had few misconceptions (mean correct answers=71.7%, 95% CI=71.0-72.4%) and the amnesia domain had the highest level of misconception (39.3%, 95% CI=37.7-40.8%). Surveyees whose friends had TBI were more knowledgeable about TBI (mean score difference=4.1%, 95% CI=1.2-6.9, P=0.01). Additionally, surveyees whose family members had experienced TBI had a better understanding of brain damage (mean score difference=5.7%, 95% CI=2.1-9.2%, P=0.002) and recovery (mean score difference=4.3%, 95% CI=0.40-8.2%, P=0.03). ConclusionThis study identified some misconceptions about TBI among young adult Africans. This at-risk population should benefit from targeted education strategies to prevent TBI and reduce TBI patients' stigmatization in Africa.
