Does academic-related anxiety contribute to an adolescent’s recovery process and return to activity after experiencing a concussion? The authors created a novel measure of academic-related anxiety (Mularoni Measure of Academic Anxiety following Concussion [MMAAC]) and administered it to adolescents following concussion in outpatient pediatric sports medicine clinics. Two previously validated measures of anxiety were also administered, and results were compared with the MMAAC scores as well as the lengths of time for return to school and sports. Results show that higher MMAAC scores positively correlate with the length of time an adolescent needs to return to school. Study results indicate that the MMAAC reliably measures academic-related anxiety in adolescents suffering from concussions and can be helpful in predicting a basic timetable for return to school. The authors believe that this brief survey can be used by physicians in clinic to evaluate anxiety and assist with return to school expectations to provide comprehensive recovery support.
