Abstrakt

Samobójstwa stanowią wszechstronną miarę dobrego samopoczucia psychicznego, stabilności emocjonalnej, a także satysfakcji z życia, a ostatnio zostały uznane przez Światową Organizację Zdrowia (WHO) za główny problem zdrowotny na świecie. Państwa G20 są potęgą w obszarze globalnego zarządzania polityką gospodarczą, a tym samym mają zdolność wpływania na kształtowanie się globalnego wskaźnika samobójstw. Stosując metodę SPSM do trzech generacji testów pierwiastka jednostkowego, w opracowaniu zbadano własności integracyjne samobójstw w krajach G20 w latach 1990–2017. Wyniki uzyskane ze wszystkich trzech generacji testów dostarczają mocnych dowodów na utrzymywanie się samobójstw w większości państw członkowskich G20. Uzasadnia to istnienie aktualnego programu strategicznego forsowanego przez WHO, zmierzającego do redukcji odsetka samobójstw do docelowego poziomu 10 procent. Wskazano ponadto, że takie strategie powinny rozprzestrzeniać się z państw G20 na pozostałe państwa świata.
