Brief intensive EMDR therapy for PTSD in adults with mild intellectual disability or borderline intellectual functioning and behavioural problems: a multiple baseline design study
Bibliographic record
Abstract
Background: Individuals with mild intellectual disability (MID; IQ 50–70) or borderline intellectual functioning (BIF; IQ 70–85) are at an elevated risk of post-traumatic stress disorder (PTSD), with PTSD symptoms possibly associated with behavioural problems. It is important to test the effectiveness of trauma-focused treatments, such as eye movement desensitisation and reprocessing (EMDR) therapy, for adults with MID–BIF, PTSD, and severe behavioural problems.Objective: To determine the safety and effectiveness of brief intensive EMDR therapy carried out by a team of rotating therapists in adults with MID-BIF, PTSD, and severe behavioural problems.Methods: Using a randomised non-concurrent multiple baseline between-subjects design, 11 adults with MID-BIF, PTSD, and severe behavioural problems received a maximum of 16 intensive EMDR sessions twice daily for a maximum of two weeks from six different EMDR therapists. Primary outcome measurements included severity of PTSD symptoms, PTSD diagnostic status, and adverse events. Secondary outcome measurements included the frequency and severity of behavioural problems, presence of adaptive behaviour, and the use of involuntary care. Outcome measurements were assessed at baseline, during the intervention and post-intervention phases, and at the follow-up phases, and subject to randomisation tests for statistical significance.Results: Intensive EMDR therapy carried out by a team of rotating therapists resulted in significant decreases in PTSD symptoms (Mdifference = 15.84, p < .001) with nine of 11 participants no longer meeting the PTSD diagnostic criteria immediately following treatment and at the 9-week follow-up. Randomisation tests revealed no significant changes in adaptive behaviour, frequency, and severity of behavioural problems. Additionally, no decrease in the use of involuntary care measures was observed. One participant dropped out; no adverse events were observed.Conclusions: Brief intensive EMDR therapy for individuals with MID-BIF and severe behavioural problems, conducted by a team of rotating therapists, can be done safely and effectively to reduce PTSD symptoms.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
