Abstract

Background

This study explored the experiences of individuals with mild intellectual disability (MID: IQ 50-70) or borderline intellectual functioning (BIF: IQ 70-85), post-traumatic stress disorder (PTSD), and severe behavioural problems, with brief Intensive EMDR therapy delivered by a team of rotating therapists.

Purpose

Preliminary research indicates that Intensive EMDR therapy with a team of rotating therapists is effective in treating PTSD in individuals with MID-BIF. To optimise treatment outcomes, it is important to understand how they experience this treatment format.

Methods

In-depth semi-structured interviews were conducted with three adults with MID-BIF and severe behavioural problems, before and after therapy. Interviews with three professional caregivers (before and after therapy), three EMDR therapists (after therapy), and field notes were used to contextualise the experiences of the participants.

Results

Interpretative phenomenological analysis (IPA) revealed that participants started Intensive EMDR therapy with rotating therapists holding high expectations. One participant discontinued early, two completed treatment, and all reported positive experiences with both the intensive format and therapist rotation model. The intensity was seen to support continuity and engagement, particularly compared to weekly therapy sessions. Minimal involvement of the (professional) support systems was also observed.

Conclusions

Participants with MID-BIF and severe behavioural problems generally reported positive experiences with brief Intensive EMDR therapy delivered by a team of rotating therapists.
