Mental pain, communication difficulties, and medically serious suicide attempts: A case-control study.

Medical severe suicide attempts (MSSA) are epidemiologically very similar to individuals who complete suicide. Mental pain variants (e.g., hopelessness), facets of communication difficulties (e.g., self-disclosure), as well as socio-demographic and clinical characteristics were assessed. The MSSA had significantly higher communication difficulties than the other 3 groups. Moreover, the interaction between mental pain and communication difficulties explained some of the variance in suicide lethality, above and beyond the contribution of each component alone.
