Elevated interoceptive deficits in individuals with eating disorders and self-injurious thoughts and behaviors: A replication and extension

Introduction People with eating disorders (EDs) frequently report self-injurious thoughts and behaviors (SITBs). We aimed to replicate and extend findings demonstrating greater interoceptive deficits according to SITB severity. We predicted that interoceptive deficits would be greater among people with versus without lifetime SITBs and among those with multiple suicide attempts compared with single attempts or […]

Reconnecting to Internal Sensations and Experiences (RISE): An online, multi-session intervention improves interoceptive sensibility for military personnel

Objective This preregistered randomized controlled trial tested the effects of a four-session, online interoceptive awareness intervention relative to an active comparator, matched for time and attention on interoception and suicidal ideation. Method Participants (N = 195; 69% male; mean age = 37) were active duty service members (62%) and veterans (38%) who completed measures of interoceptive sensibility, interoceptive accuracy, […]

Exploring the link between interoceptive body awareness and suicidal orientation in university students: A cross-sectional study

Introduction: The transition to college life can impact the mental health of students. There are mental health care strategies that promote connection with the body’s internal signals, which can help to improve mental well-being, manage emotions, and reduce the risk of suicide in university students. Aim: This study aimed to examine the association between interoceptive […]

Disrupted interoception in Military Service Members and Veterans with a history of suicidality

Introduction This project tested whether Service Members (SM) and Veterans with current suicidal ideation or a history of suicide attempt had greater interoceptive dysfunction than SM and Veterans with past or no suicidal ideation. Method Participants (N = 195; 69% male) were SM (62%) and Veterans (38%) who completed measures of suicidal thoughts and behaviors and subjective […]

Interoceptive deficits differentiate suicide groups and associate with self-injurious thoughts and behaviors in a military sample

Objective Previous research shows that interoceptive deficits are associated with harmful behaviors such as nonsuicidal self-injury (NSSI), eating disorder pathology, and suicide attempts. The present study replicates and extends this area of research by examining the association between interoceptive deficits and suicidality in a military sample. Method In Study 1, respondents to an online survey […]

A multi-measure examination of interoception in people with recent nonsuicidal self-injury

Objective Self-injurious behaviors (SIB) are highly dangerous, yet prediction remains weak. Novel SIB correlates must be identified, such as impaired interoception. This study examined whether two forms of interoceptive processing (accuracy and sensibility) for multiple sensations (general, cardiac, and pain) differed between people with and without recent nonsuicidal self-injury (NSSI). Method Participants were adults with […]

Diminished body trust uniquely predicts suicidal ideation and nonsuicidal self-injury among people with recent self-injurious thoughts and behaviors

Introduction Self-injurious thoughts and behaviors (SITBs) are difficult to predict, and novel risk factors must be identified. While diminished interoception is associated with SITBs cross-sectionally, the current study assesses whether multiple measures of interoception predict future SITBs. Methods Adults (N = 43) with recent SITBs completed assessments of interoception during a baseline visit. Participants then completed biweekly […]

Interoceptive abnormalities and suicidality: A systematic review

Dysfunction of interoception (i.e., difficulties sensing the physiological state of one’s own body) is increasingly linked to different mental health disorders and suicidal outcomes. The aim of this study was to systematically review the literature on the association between suicidality and interoception, as well as identify potential confounders and mediators of the relationship. We conducted […]

Diminished responses to bodily threat and blunted interoception in suicide attempters

Psychological theories of suicide suggest that certain traits may reduce aversion to physical threat and increase the probability of transitioning from suicidal ideation to action. Here, we investigated whether blunted sensitivity to bodily signals is associated with suicidal action by comparing individuals with a history of attempted suicide to a matched psychiatric reference sample without […]
