Identifying Psychological Strains in Suicide Notes

Abstract

The Strain Theory of Suicide and mental disorders proposes that psychological strains precede suicidal behaviors and psychiatric disorders. This study was designed to test the theory with a large sample of suicide notes collected from Tasmania, Australia. The content of 261 suicide notes was analyzed for the presence of four psychological strains. It was found that 39.6% of the 261 suicide notes had at least one of the four psychological strains, with aspiration and coping strains being the most prevalent. We then compared the ratings of psychological strains with ratings of thwarted belonging and perceived burdensomeness and found that the presence of aspiration strain and coping strain was associated with thwarted belonging, while aspiration and deprivation strains were associated with perceived burdensomeness.
