Abstract

Background

Prior research has validated the construct of a suicide crisis syndrome (SCS), a specific psychological state that precedes and may precipitate suicidal behavior. The feeling of entrapment is a central concept of the SCS as well as of several other recent models of suicide. However, its exact relationship with suicidality is not fully understood. In efforts to clarify the exact role of entrapment in the suicidal process, we have examined if entrapment mediates the relationship of other components of the SCS, including ruminative flooding, panic-dissociation, fear of dying and emotional pain, with suicidal ideation (SI) in recently hospitalized psychiatric inpatients.

Methods

The Suicide Crisis Inventory (SCI) and Beck Scale for Suicidal Ideation (BSS) were administered to 200 high-risk adult psychiatric inpatients hospitalized following SI or suicide attempt, assessing SCS and SI levels at admission, respectively. The possible mediation effects of entrapment on the relationship between the other components of the SCS and SI at admission were evaluated.

Results

Entrapment significantly and fully mediated the relationship of ruminative flooding, panic-dissociation, and fear of dying with SI, with no direct relationships between these variables and SI reaching statistical significance. Further, no reverse mediation relationships between these variables and SI were found, indicating that the mediation effects of entrapment were unidirectional. While entrapment did mediate the association between emotional pain and SI, the direct relationship between emotional pain and SI was also significant. Moreover, in reverse mediational analysis, emotional pain was a partial mediator of the relationship between entrapment and SI.

Conclusion

Entrapment and emotional pain may have a more direct association with SI than the other components of the SCS, including ruminative flooding, panic-dissociation, and fear of dying, the effects of which are mediated by the former. This suggests entrapment and emotional pain may represent key symptomatic targets for intervention in acutely suicidal individuals. Further research is needed to determine the relationship of these constructs to suicidal behavior.
