Clinical features of suicide attempts in adults with autism spectrum disorders
Abstract
Objective The objective of this study was to investigate the frequency and clinical features of suicide attempts in adults with autism spectrum disorders (ASDs).Methods We enrolled 587 consecutive patients aged 18 or over who attempted suicide and were hospitalized for inpatient treatment. Psychiatric diagnoses, suicide attempt frequency and clinical features were compared between ASD and non-ASD patients.Results Forty-three (7.3%) of the 587 subjects who attempted suicide had ASDs. The incidence of patients with mood disorders was significantly lower (Fisher's Exact Test, P=.043) and that of those with an adjustment disorder was significantly higher (Fisher's Exact Test, P<.001) in the ASD group than in the non-ASD group. The average length of stay at both the hospital and intensive care unit in the ASD group was longer than that in the non-ASD group (z=-2.031, P=.042; z=-2.322, P=.020, respectively).Conclusions ASDs should always be a consideration when dealing with suicide attempts in adults at the emergency room.

Individuals with ASD who have attempted suicide had persistent rather than spontaneous stressors, used more lethal means, and were less connected to psychiatric services than the general population.
“Kato and colleagues (2013) stated that “individuals with ASD who have attempted suicide (a) had persistent rather than spontaneous stressors, (b) used more lethal means, and (c) were less connected to psychiatric services than the general population” [7].”
Individuals with ASD may be more likely to succeed in their first suicide attempt.
“This suggests that individuals with ASD may actually be more likely to succeed in their first suicide attempt [7].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
