When I was a counselor for Crisis Text Line, we saw a dramatic spike in clients when 13 reasons came out. They keep data on all kinds of things, and that was a noticeable bump.
I am following up on this because I ran across a paper by chance that examined trends in Crisis Text Line messages around the time of the show. It appears that there was a statistically significant spike in conversation counts on April 5-6, 2017, approximately five days after the release of the show, which was followed by a significant and sustained decrease in conversation counts through May 18. The paper is open-access and can be found
here.
The authors referenced a separate study (
here) that asked youths who presented to an emergency department for suicide-related concern about their experiences with
13 Reasons Why. About half of the youths who responded to a question about the show's impact reported feeling that the show had increased their risk for suicide. Furthermore, identification with Hannah Baker was found to be correlated with perceiving that the show increased suicide risk. There were mixed results with whether or not youths were more likely to talk to others about mental health concerns.
Correlation is not causation, etc., but I find it interesting that the youths themselves are reporting increased risk due to the show.
