Conclusion
Increased suicidal ideation was observed in the young and middle-aged with suicide-related or mental health consultation-related internet use. Those who disclosed their suicidal ideation up until a month ago, disclosed their suicidal ideation within the previous month, and browsed for information about suicide methods within the previous month had significantly increased suicidal ideation 7 to 8 weeks later. Meanwhile, mental health consultation via the internet was not useful but may have worsened depression/anxiety. Therefore, regulation of information regarding suicide on the internet should be promoted as a health policy. As a next challenge, new and more effective interventions for vulnerable populations with suicide-related internet use should be developed.

「死にたい気持ちを匿名の他者に対して打ち明けることや自殺方法を閲覧することは自殺念慮の悪化につながる」
「匿名の他者にメンタルヘルスの相談をすることは自殺念慮を悪化させないが、抑うつ・不安感の悪化につながる」
ネットを経由した精神健康相談は not useful だと結論している。

ネットを経由した、どんな相談なのかが問題だけど、まあ、こんな結論があってもおかしくない。
