A prospective study of the relationship between adverse life events and trauma in adults with mild to moderate intellectual disabilities.

Researchers followed adults with mild to moderate intellectual disability for six months. They tracked who had adverse life events like bereavement, illness, or bullying. Then they used the LANTS trauma scale to see if those events led to trauma symptoms.

Adults who faced adverse events showed more trauma signs six months later. The link held even after the team counted earlier trauma and baseline scores. Both self-report and caregiver LANTS scores moved in the same direction.

van Schrojenstein Lantman-de Valk et al. (2006) ran a similar six-month study and saw the same pattern: life events forecast later behavior problems and depression. Their work is the direct forerunner to this trauma-focused update.

Hove et al. (2016) zoomed in on event type. Loss of a relative and bullying were the strongest predictors of depression, matching the broad event list in Levin et al. (2014).

Vassos et al. (2023) reviewed mental-health tools for adults with ID and flagged LANTS as one of only four scales with solid reliability. That review gives you confidence that the trauma signal seen here is real, not a measurement fluke.

Screen every adult with ID on LANTS after any major life event. A quick post-event check lets you spot rising trauma early and add coping skills or counseling before behaviors escalate. Build the six-month follow-up into care plans so no client drifts after bereavement, housing loss, or bullying.
