I would have expect suicide to be less likely if you have no kin, as that’s my hypothesis. A very quick Googling doesn’t show anything up though, so I’ll update in favor of “other hypothesis I haven’t thought of yet”.
[Edit: in order to help vindicate or demolish this hypothesis, some other things it would predict: suicidal intentions would be correlated with loss of appetite, spending frugally and family-wide poverty]
The original journal article is behind a paywall, but here is Jesse Bering’s SciAm Blog post elucidating on Dr. Denys deCatanzaro’s theory on adaptive suicide.
His theory seems to be in alignment with your beliefs on the subject.
