Page 26 - Post-traumatic stress disorder in adults with mild intellectual disability: Screening, assessment, and brief intensive EMDR therapy

Chapter 1
In line with the aims of this thesis, the structure and content are outlined
as follows: Chapter 2 reports a study assessing the reliability and
construct validity of the DITS-ID-adults The DITS-ID-adults, Brief Symptom
Inventory–18, Impact of Event Scale-Intellectual Disability, Anxiety,
Depression, and Mood Scale, and Behavior Problems Inventory were
administered to 97 participants with MID-BIF and their relatives. Chapter
3 focuses on the adaptation and evaluation of both the adult self-report
and proxy versions of the Trauma Screener-Intellectual Disability (TS-ID) for
adults with MID-BIF. The TS-ID was adapted from a child and adolescent
screener and administered to participants and proxies to examine internal
consistency, validity, and optimal cut-off scores for PTSD screening. Chapter
4 examines the safety and effectiveness of brief intensive EMDR therapy
conducted by a team of rotating therapists in adults with MID-BIF, PTSD,
and severe behavioural problems. Using a randomised non-concurrent
multiple baseline between-subjects design, PTSD symptoms, diagnostic
status, adverse events, behavioural problems, adaptive behaviour, and
involuntary care use were assessed. Chapter 5 explores the experiences of
individuals with MID-BIF, PTSD, and severe behavioural problems with brief
intensive EMDR therapy delivered by a team of rotating therapists. In-depth
semi-structured interviews were conducted with participants, professional
caregivers, and EMDR therapists before and after therapy to understand
their treatment experiences. Chapter 6 discusses the overall findings of the
studies that are part of this dissertation.
