Aim of the study:
This paper aims to examine the efficacy of Brainspotting in ameliorating PTSD symptoms among female residential patients across three-time points.

Subject or material and methods:
This study employed a one-group pretest-posttest with delayed posttest quasi-experimental design to establish and determine causal change among different conditions. Different versions of gold-standard measures were administered to individuals with trauma exposure; the Clinician-Administered PTSD Scale 5 (CAPS-5) and the Posttraumatic Stress Disorder Checklist 5 (PCL-5). The sample comprised 13 participants at the Marillac Hills Alabang who incurred severe interpersonal trauma and suffered markedly elevated PTSD symptoms for at least two years. They received three sessions of BSP guided by a therapist's manual and were assessed at three-time points – pretreatment, posttreatment, and two weeks after the treatment completion. Primary data include self-report posttraumatic stress symptoms, which were analyzed using repeated-measures ANOVA with a Greenhouse-Geisser correction and post-hoc test with a Bonferroni correction.

Results showed significant improvements in both measures with large effect sizes from 0.859 to 0.979.

Some of the few rigorous studies that have been conducted also demonstrated similar findings indicating discharge of trauma sequelae manifested by amelioration of intrusion, low level of subjective units of distress, and regulated sensorimotor reactions

At α0.01 (99%) confidence interval, the results suggest that BSP has significant efficacy in decreasing posttraumatic stress symptoms. After the three BSP sessions, all participants were assessed with absent to mild PTSD symptoms. The effects of the program persisted during the short-term follow-up evaluation.
