Brief Summary

There is growing evidence that negative attitudes towards persons affected by suicide (i.e. persons who experience suicidality, persons who lost a loved one to suicide), so called public suicide stigma, is harmful for suicide prevention, for example by reducing social support, inhibiting help-seeking for suicidality and increasing distress as well as suicidality among stigmatized persons. Reducing public suicide stigma could therefore be an important factor of successful suicide prevention. However, reducing public suicide stigma could also be harmful, for example by increasing attitudes that suicidal behaviour is a normal and acceptable solution for crisis situations, which could decrease help-seeking for suicidality and encourage suicidal behaviour. This project will (1) develop four interventions (contact-based vs. education based, video vs. text) hypothesized to reduce public suicide stigma, (2) determine the efficacy of the four interventions with regard to reducing public suicide stigma, (3) identify additional harmful (e.g. normalization of suicidal behaviour) and beneficial intervention effects (e.g. improved attitudes to seek help) and (4) investigate pathways explaining intervention effects.
