Suicidality in a clinical and community sample of adults with mental retardation.

Lunsky (2004) asked the adults with intellectual disability about suicidal thoughts. They used the same questions doctors use in the general population. Half lived in group homes, half with family or alone.

Trained interviewers read each item aloud. They let people answer yes or no. The team also asked about mood, life events, and support.

One in three adults said they had thought about suicide. One in ten said they had already tried. These numbers match what we see in people without ID.

The adults who felt sad, had little support, or faced recent loss were more likely to report suicidal thoughts.

Fullana et al. (2007) later found almost the same rate—39 %—for depression in mild/moderate ID. Together, the two surveys show mood problems are common, not rare, in this group.

Palka Bayard de Volo et al. (2021) reviewed severe-profound ID and warned that pain, autism, or life events can mimic depression. Their caution matters: if you work with people who have limited speech, check these factors before assuming suicidality.

van Schrojenstein Lantman-de Valk et al. (2006) followed adults over time and showed that negative life events lead to later depression and behavior problems. This forward-looking study builds on Y’s snapshot by proving that early screening after loss can prevent worsening mood.

You cannot assume that people with ID are protected from suicidal thoughts. Screen every adult at intake, even if they seem happy or live with family. Use plain-language questions or picture cues. If the person endorses any item, follow your facility’s risk protocol and refer for mental-health evaluation. Early detection saves lives.
