EEG and psychological assessment datasets: Neurofeeedback for the treatment of PTSD

Psychological assessments were conducted through clinical interviews, to collect psychometric data for twenty-nine female survivors of the 1994 genocide against the Tutsi in Rwanda, before and after an intervention aimed at reducing Post-Traumatic Stress Disorder (PTSD) symptom severity. Three measures of trauma and four measures of wellbeing were assessed using empirically validated standardised assessments. The participants were assigned to a control group (n = 9), a motor-imagery group (MI, n = 10), and a neurofeedback group (NF, n = 10). Participants in the latter two groups received a Brain-Computer Interface (BCI) based training as a treatment intervention over a period of two weeks between the pre- and post- clinical interviews. The training involved presenting feedback visually via a game, based on real-time analysis of the EEG recorded data during the BCI-based treatment session. Participants were asked to regulate (NF) or intentionally modulate (MI) brain activity to affect/control the game.”
