The small island of Nantucket, MA has seen 3 teen suicides in a short period of time, according to the New York Times. Very sad. Statistically, three suicides in a high school of 400 represents a meaningful cluster, and a possible contagion effect. Whether it is or it isn’t contagion in Nantucket (it is impossible to know for sure and the article suggests some disagreement in this case), the key thing for clinicians to know is that vulnerability to contagion has been documented in adolescents. Clinicians working with adolescents at risk at the time of a public or peer suicide should consider reassessing their clients’ risk for suicide when news of a peer death becomes public.
