Abstract

Background: The aims of the study were to (a) revise the Impact of Event Scale – Revised for use with people with intellectual disabilities (IDs), creating the Impact of Event Scale – Intellectual Disabilities (IES-IDs), (b) assess the reliability of the IES-IDs, and (c) compare it to an existing measure post-traumatic stress disorder symptomatology, namely the Lancaster and Northgate Trauma Scale (LANTS), along with measures of anxiety and depression.

Results: Fifteen percent of the sample had encountered five or more traumatic events. The IES-IDs and the LANTS had good to excellent internal consistency and test-retest reliability. Both measures correlated with self-report measures of depression and anxiety, although the strength of this correlation was greater with the LANTS. There was a significant positive correlation between trauma frequency and the IES-IDs, but not the LANTs

Conclusions: Both the IES-IDs and the LANTs appear to have good reliability.
