Examination of interoception along the suicidality continuum

Abstract

Objective: Interoception deficits have been associated with various points on the suicidality continuum. Most research, however, has focused on general, rather than specific facets of, interoception. This study compared individuals with lifetime suicidal ideation, plans, and attempts using a multidimensional assessment of interoception.

Method: A total of 537 adults completed measures of their interoception and lifetime suicide histories.

Results: Individuals with lifetime suicidal ideation reported more worry about their bodily sensations. Those with lifetime suicide attempts reported a greater tendency to distract themselves from bodily sensations and less self-regulation using bodily sensations. Individuals at all points of the suicidality continuum reported less trust of their bodily sensations.

Conclusion: These findings suggest that interoception may be impaired in those with a history of suicidal thoughts and behaviors. Longitudinal designs are needed to parse apart the interplay of these variables and directionality of these relationships.

Keywords: interoception; suicidal ideation; suicide; suicide attempts; suicide plans.
