The Effectiveness of Neurofeedback Training on Reducing Symptoms of War Veterans with Posttraumatic Stress Disorder

Objective: Current study aimed to determine the effectiveness of neurofeedback training on&nbsp;decreasing posttraumatic stress disorder (PTSD) in veterans. Methods: The present study is an experimental research with pretest, posttest, and control&nbsp;group design. Patients with PTSD were randomly selected by purposive sampling method and&nbsp;assigned in experimental (15 persons) and control groups (15 persons). Data were collected&nbsp;by the posttraumatic stress disorder checklist (PCL). After the pretest, experimental group received neurofeedback training for 20 sessions, 3 days per week. Groups were evaluated for&nbsp;intensity of symptoms by PCL questionnaire at the beginning and end of the study. Data were&nbsp;analyzed using analysis of covariance (ANCOVA) by SPSS version 22. Results: The results of covariance test showed that there are differences between adjusted&nbsp;mean of PTSD symptoms in groups in posttest by removing the impact of pretest scores. Conclusion: Our findings showed that neurofeedback training has significantly decreased the&nbsp;score of total symptoms (F=22.506, P<0.001).
