Abstract:This research was conducted to develop an instrument to diagnose Posttraumatic stress disorder (PTSD) of adults with mild Intellectual Disability (ID). Diagnosing PTSD of adults with mild ID requires a different approach compared to the general population. Because these people experience life events differently and the symptoms can be expressed differently. As a guide for this study the Anxiety Disorders Interview Schedule for Children (ADIS-C) was used, a semi-structured interview that researches the criteria of PTSD in the DSM-IV-TR and DSM-V. There were two goals for this study: (1) Adjusting the ADIS-C for children with mild ID for adults with mild ID. (2) Testing the applicability of the new semi structured interview (ADIS-LVB) in a pilot study. To work on these goals this research required four steps: (1) literature review, (2) interviews with expert psychologists who work with people with mild ID and knowledge of PTSD, (3) adjusting the semi-structured interview and (4) a pilot study of the ADIS-LVB with fifteen people with mild ID. The results of the interviews were compared with the clinical assessment of the treating psychologists. After the interviews seven persons out of fifteen were found to meet the criteria of PTSD according to the DSM-IV-TR and the DSM-V. According to the clinical assessment of the treating psychologists two people have the diagnose PTSD. The pilot study showed that 66% of the outcome with the ADIS-LVB corresponded with the assessment of the treating psychologists. The clients with mild ID generally said that they experienced the interview as pleasant, but some sentences were unclear or too long. Based on the result the ADIS-LVB was adjusted. Eventually the ADIS-LVB was created which can be used as a screening instrument to research the criteria of PTSD of people with mild ID.
