RESUMEN
BACKGROUND: This study aimed to examine the effect of an online psychological intervention on academic burnout of undergraduate history students in Nigeria. METHOD: The sample for the study consists of burned-out undergraduate history students selected randomly from public universities. A total of 18 undergraduate history students with moderate to high burnout symptoms were randomly allocated to the online intervention group, while 17 were randomly assigned to the waitlist control group. RESULTS: The use of online rational emotive behavior therapy (online REBT) effectively reduced academic burnout and sustained this significant reduction among Nigerian undergraduate history students compared with a waitlist control condition. CONCLUSION: Online rational emotive behavior therapy intervention delivered to undergraduate history students brought about a significant decrease in academic burnout. Further studies should expand the benefits of online psychological intervention for burnout treatment among Nigerian undergraduate history students.
