Abstract
In the aftermath of psychological trauma, many individuals experience perturbations in interoception, a term that broadly references the ability to accurately detect body signals and integrate these signals with emotional states. These interoceptive disruptions can manifest in different ways, including blunting or amplification of sensitivity to internal physiological signals. In this chapter we review extant neurophysiological research on interoception in trauma-exposed populations, with a particular focus on the effects of chronic interpersonal trauma, such as childhood maltreatment and racial discrimination. We explore research that used different types of interoceptive assays, from self-report measures to electrophysiological and neuroimaging tools to characterize the disruptions in pain perception, interoceptive acuity, and physiological responses that may arise after a traumatic event. Finally, we discuss interventions that are designed to target interoceptive mechanisms, from exposure-based therapies to mindfulness-based practices, as well as future directions in trauma interoception research.

Body Awareness as a Protective Factor against Suicidal Orientations in College Students. Behav Sci (Basel) 2024; 14:358. [PMID: 38785849 PMCID: PMC11118123 DOI: 10.3390/bs14050358] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2024] [Revised: 04/16/2024] [Accepted: 04/22/2024] [Indexed: 05/25/2024] Open
Abstract
In this study, binary logistic regression and linear regression analyses were used to examine the relationship between interoceptive body awareness and suicidal orientation among Colombian university students. Additionally, the bootstrap technique was employed to resample and estimate the distribution of the data. The results support the idea that greater interoceptive awareness may protect against suicidal orientation by improving emotional regulation. An inverse relationship was found between interoceptive awareness and suicidal ideation. These findings align with previous literature emphasizing the importance of body awareness for emotional well-being. Further longitudinal research is needed to explore this relationship more deeply.

Abstract
Interoception (e.g., abilities to recognize/attend to internal sensations) is robustly associated with psychopathology. One form of interoception, body trust, is relevant for the development of disordered eating and suicidal thoughts/behaviors. However, measures of body trust are narrow, despite research suggesting body trust is multifaceted. The aim of this study was to develop a comprehensive measure of body trust: The Body Trust Scale (BTS). 479 U.S. adults completed self-report surveys containing the BTS and psychopathology measures. Exploratory and confirmatory factor analyses revealed a three-factor structure: Comfort with One's Body, Physical Attractiveness, and Comfort with Internal Sensations. Factors showed strong construct, convergent, and divergent validity, as well as moderate predictive validity for suicidal thoughts/non-suicidal self-injury. Furthermore, factors showed strong internal consistency, test-retest reliability, and were invariant across the gender binary. The BTS can be used in research and clinical settings to understand how specific facets of body trust relate to psychopathology.

Abstract
BACKGROUND Avoidant/restrictive food intake disorder (ARFID) is a serious, albeit under-researched, feeding or eating disorder. This exploratory study utilized data from adult respondents to the National Eating Disorders Association online eating disorder screen to validate items assessing the presence of ARFID and examine the prevalence, clinical characteristics, and correlates of a positive ARFID screen. METHODS Among 50,082 adult screen respondents between January 2022 and January 2023, the prevalence of a positive ARFID screen was calculated. Chi-square tests and t-tests compared demographics, eating disorder attitudes and behaviors, suicidal ideation, current eating disorder treatment status, and eating disorder treatment-seeking intentions between respondents with possible ARFID and other eating disorder diagnostic and risk categories. Clinical characteristics of respondents with possible ARFID were also examined. RESULTS 2378 (4.7%) adult respondents screened positive for ARFID. Respondents with possible ARFID tended to be younger, male, and have lower household income, and were less likely to be White and more likely to be Hispanic/Latino than most other diagnostic/risk groups. They had lower weight/shape concerns and eating disorder behaviors than most other diagnoses and higher BMI than those with AN. 35% reported suicidal ideation, 47% reported intentions to seek treatment for an eating disorder, and 2% reported currently being in treatment. The most common clinical feature of ARFID was lack of interest in eating (80%), followed by food sensory avoidance (55%) and avoidance of food due to fear of aversive consequences (31%). CONCLUSIONS Findings from this study indicated that ARFID was prevalent among adult screen respondents and more common among individuals who were younger, male, non-White, Hispanic, and lower income relative to those with other eating disorders, at risk for an eating disorder, or at low risk. Individuals with possible ARFID frequently reported suicidal ideation and were rarely in treatment for an eating disorder. Further research is urgently needed to improve advances in the assessment and treatment of ARFID and improve access to care in order to prevent prolonged illness duration.

Abstract
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 body awareness variables and suicidal orientation in a sample of 169 undergraduate students in Colombia. METHODS An observational, cross-sectional study was conducted in 2023 with Colombian students as the participants. RESULTS The findings revealed a significant and moderately negative correlation between the Multidimensional Assessment of Interoceptive Awareness (MAIA) total score and the Inventory of Suicide Orientation (ISO-30) total score (r = -0.54, p < 0.001). Confidence and self-regulation were identified as the most influential factors in the relationship between MAIA and ISO-30. Significant correlations were observed (p < 0.001), indicating moderate correlation values ranging from -0.43 to -0.57. DISCUSSION Our findings support the existence of a negative correlation between interoceptive body awareness and suicidal orientation. Further research is needed to better understand this relationship and to develop specific interventions based on body awareness to prevent suicide orientation. CONCLUSION There are practical implications associated with recognizing the importance of body awareness in relation to decreasing suicidal orientation, and multidisciplinary teams addressing mental health can incorporate this knowledge.

Abstract
OBJECTIVE Increased weight suppression, the difference between an individual's highest and current weight at present height, predicts binge eating among eating disorder samples. Less is known about this relationship in non-clinical samples of individuals with a history of higher weight. METHODS Lifetime highest BMI was tested as a moderator of the relationship between weight suppression and binge eating in three independent samples (N = 1740). RESULTS At the bivariate level, weight suppression was not associated with binge eating in any sample (p's ≥ 0.20). Lifetime highest BMI moderated the relationship between weight suppression and binge eating in Sample 1 (p = .04), such that greater weight suppression was associated with lower binge eating among those with a history of higher weight (i.e., BMI = 40 kg/m2). In Samples 2 and 3, the lifetime highest BMI by weight suppression interaction term was not significant and dropped from the model (p's = 0.10-0.12). Accounting for age, gender, and lifetime highest BMI, greater weight suppression was associated with lower binge eating scores (p's < 0.04). A meta-analysis combining results revealed a small but significant interaction effect (r = 0.07, p = .02). CONCLUSIONS Findings highlight the importance of investigating the generalizability of eating disorder risk and maintenance theories across the weight spectrum. Weight loss may not increase risk for binge eating among those with a history of higher weight. Future work should replicate and extend this finding using longitudinal designs. More research is needed to elucidate which weight loss motivations and/or behaviors are most closely linked to binge eating.

Abstract
BACKGROUND Interoception plays a vital role in human cognition and emotion and is an increasingly important part of clinical studies of mind-body approaches and mental health. Interoceptive awareness (IA) encompasses numerous mind-body components and can be assessed by employing a self-report measure such as the Multidimensional Assessment of Interoceptive Awareness (MAIA), which has been adapted and validated across several countries and is used in experimental and clinical settings. In this study, the MAIA-2, which was developed due to the psychometric shortages of MAIA, was thoroughly translated, and its psychometric features were examined in a sample of 306 Norwegian-speaking participants (81% females, ages 16 through 66 plus). METHODS The participants completed the MAIA-2 Norwegian version (MAIA-2-N) and the COOP/WONCA Functional Assessment Charts measuring psychological, physical, and overall health. The following psychometric qualities of the MAIA-2 were investigated: factor structure, internal consistency, and the moderating role of gender. RESULTS Confirmatory Factor Analysis (CFA) revealed that an 8-factor model of MAIA-2-N provided the best fit. Also, a bifactor model revealed a proper fit. Good internal consistency and a moderating role of gender, age, and education on the relationships between certain MAIA-2-N factors and health were observed. CONCLUSIONS The MAIA-2-N is an adequate measure of IA in Norwegian-speaking individuals. The factor-structure corresponds with the original MAIA-2 and it shows good internal consistency. Some moderating effects of gender were observed, particularly related to the relationship between IA and physical and psychological state, with the physical state/fitness more closely linked to IA in males and psychological state in females.

Abstract
BACKGROUND Individuals with eating disorders (EDs) often struggle with markedly low self- esteem and are at risk for suicidal behavior. Dissociation and perceived burdensomeness are often cited as facilitators of suicidal outcomes. Specifically, perceived burdensomeness is comprised of self-hate and liability on others, although it remains unclear which variables most heavily influence suicidal behavior in EDs. METHODS In a sample of 204 women with bulimia nervosa, the present study examined the potential impact of self-hate and dissociation on suicidal behavior. We hypothesized that suicidal behavior would be equally, and potentially more strongly, related to self-hate than dissociation. Regression analyses investigated the unique effects of these variables on suicidal behavior. RESULTS Consistent with our hypothesis, a significant relationship emerged between self-hate and suicidal behavior (B = 0.262, SE = 0.081, p < .001, CIs = 0.035-0.110, R-squared =0.07) but not between dissociation and suicidal behavior (B = 0.010, SE = 0.007, p = .165, CIs = -0.389-2.26, R-squared =0.010). Additionally, when controlling for one another, both self-hate (B = 0.889, SE = 0.246, p < .001, CIs = 0.403-1.37) and capability for suicide (B = 0.233, SE = 0.080, p = .004, CIs = 0.076-0.391) were uniquely and independently associated with suicidal behavior. LIMITATIONS Future work should include longitudinal analyses to understand temporal relationships among study variables. CONCLUSIONS In sum, when considering suicidal outcomes, these findings support a view that highlights personal loathing rooted in self-hate rather than de-personalizing aspects of dissociation. Accordingly, self-hate may emerge as a particularly valuable target for treatment and suicide prevention in EDs.

Abstract
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 and objective interoceptive dysfunction. Participants were split into the following suicide groups: no suicidality, lifetime ideation, current ideation, and past attempt. Planned orthogonal contrasts tested for differences. RESULTS The combined suicidality group (lifetime ideation, current ideation, or past attempt) had worse body trust relative to the no suicidality group, and the current ideation group had worse body trust relative to those with lifetime ideation. Those with a history of suicide attempt had worse body appreciation than the combined group of ideators, and those with current ideation had worse body appreciation relative to those with lifetime ideation. The groups did not differ on objective interoception. CONCLUSION Interoception is disrupted among individuals with suicidality histories within a predominantly male-identified military sample. Individuals with current suicidal ideation had both worse body trust and appreciation relative to those with past ideation. Suicide risk assessments may benefit from including questions related to body trust.

Abstract
Most DSM-5 eating disorder diagnoses are associated with elevated suicide risk; however, little is known about the relationship between Avoidant/Restrictive Food Intake Disorder (ARFID) and suicidal ideation. The aim of the current study was to examine suicidal ideation within an adult ARFID sample. Patients with eating disorders (N = 936), some of whom met criteria for a current DSM-5 diagnosis of ARFID (n = 79), completed the Beck Depression Inventory II Item 9, regarding suicidal ideation. The study was conducted within an eating disorder treatment facility that offers inpatient, residential, partial hospitalization program, and intensive outpatient levels of care. Findings suggest no significant pairwise differences in suicidal ideation prevalence between participants with ARFID and those with any other ED diagnosis. Thorough screening for suicidal thoughts and risk among those with ARFID is warranted at all levels of care. We suggest that future research expand upon this work in a larger adult ARFID sample.

Abstract
Fears of pain, injury, and death may represent key barriers to acting on suicidal thoughts. Dissociation, which involves a disconnection from one's body, may reduce fears and sensations of pain associated with harming the body, in turn facilitating suicide attempts. This study examined whether dissociation differentiated individuals with a history of suicide attempts from those with a history of suicide ideation, and investigated whether other relevant constructs explain this relationship. Sample 1 included 754 undergraduates (Mage = 21, 79% female) who completed a battery of self-report measures. Sample 2 included 247 undergraduates (Mage = 19, 74% female) who completed a self-report measure of dissociation, a clinical interview regarding suicide history, and four counterbalanced behavioral pain tolerance tasks. In both samples, dissociation was elevated in lifetime attempters compared to ideators (d = 0.28; d = 0.46; ps = 0.01) and slightly elevated in lifetime ideators compared to nonsuicidal individuals (d = 0.19, p = .02; d = 0.24, p = .47), though this effect was non-significant in the latter sample. In Sample 1, dissociation no longer differentiated attempters from ideators after controlling for clinical covariates. In Sample 2, dissociation was unrelated to behavioral pain tolerance tasks, and these tasks did not account for the association between dissociation and attempts. Overall, dissociation differentiated individuals with a history of suicide attempts from those with ideation alone in both samples. Pain tolerance did not explain this association; instead, it is possible that the relationship of dissociation to suicide attempts is due to "third variables" associated with both phenomena, such as symptoms of borderline personality disorder or posttraumatic stress disorder.

Abstract
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 a systematic review of four databases, allowing for critical examination of the role of different measures of interoception (accuracy, sensibility, awareness, cognitive/emotional evaluation) across the suicide continuum (ideation, plans, attempts, deaths). The search strategy identified 22 studies (14,988 participants). Preliminary but limited evidence was found for impaired interoceptive accuracy among those reporting suicide attempt histories. We found evidence of interoceptive sensibility disturbances across the suicide continuum, including experiences of not trusting one's own body sensations and impaired abilities to sustain and control attention to such sensations. Consistent evidence was also reported for disturbances related to cognitive and emotional evaluations of interoceptive sensations. The latter was particularly pronounced for those reporting suicide attempts, relative to those reporting suicidal thinking or planning alone. Overall, this review's results suggest that interoceptive abnormalities are potentially important indicators of risk for suicidal thinking, intentions, and behaviors. However, due to the inconsistent adjustment for variables of interest, and cross-sectional designs, it is unclear whether interoceptive changes and disturbances have a direct role, or whether the association is explained and mediated by key third variables (e.g. depression, disordered eating, emotional dysregulation). We discuss the implications with respect to suicidal risk and therapeutic interventions.

Abstract
Risk factors that are strongly associated with suicide and are amenable to intervention are in need of discovery. This three-study investigation demonstrates that an intervention designed to improve interoception-one potential suicide risk factor-may reduce suicide-related outcomes. Study 1 included 136 undergraduate participants and found that relative to a control condition, participating in a progressive muscle relaxation exercise was associated with reduced implicit identification with suicide through greater body trust, which is one domain of interoception that is consistently linked to suicide-related outcomes. Study 2 included 97 MTurk participants and found that relative to a control condition, participating in a body functionality writing exercise was associated with greater awareness of the body as a whole. Study 3 was a pilot study of a four-session online intervention designed to increase interoception. Study 3 included a sample of 22 clinical participants who completed pre- and postintervention assessments. Participants rated the intervention as highly acceptable and moderately effective. Moreover, the intervention was associated with improvements in interoception and reductions in suicidal ideation, general psychological symptoms, and disordered-eating symptoms. Overall, these findings indicate that our online interoceptive awareness training is acceptable and may be associated with improvements in clinical outcomes. Randomized controlled trials are needed to explore whether the intervention's purported mechanism-improved interoception-leads to changes in clinical outcomes.

Abstract
Impairments in interoception have been linked to self-injurious behaviors, and capability for suicide may account for this relationship. However, past studies have relied primarily on self-report and unidimensional measures. The present study aimed to replicate and extend previous findings by examining the relationship between interoceptive dysfunction, pain tolerance, and self-injurious behaviors using a multidimensional and multi-method approach. A sample of 245 undergraduate students (Mage = 19.27 years, SD = 2.81; 73.7% female, 72.% White/European American), who reported lifetime suicidal ideation on a screening survey completed a battery of self-report measures, four counterbalanced pain tolerance tasks, and a clinical interview assessing their self-injurious behaviors. A tendency to stay attuned to bodily sensations was significantly related to decreased pain tolerance. Only trust in one's body was significantly related to decreased presence of lifetime suicide attempts. No other facets of interoception or pain tolerance were significantly associated with self-injurious behaviors. Overall, these findings contrast with previous findings that capability for suicide may account for relations between interoceptive dysfunction and self-injurious behaviors. Nonetheless, the results of this study provide important information on the factor structure of interoceptive dysfunction and pain tolerance, and highlight the importance of careful selection of measures and operationalization of key constructs, particularly interoceptive dysfunction and pain tolerance.

Abstract
Previous research has demonstrated that both suicidal ideation (SI) and eating disorders (EDs) are associated with poor interoceptive awareness (IA). Suicidality research has demonstrated that the IA dimension of lower body trust is associated with SI, suicide plans, and suicide attempts. Similarly, in ED samples, recent research supports that low body trust has been the most robust dimension of IA associated with eating pathology. However, to date, research is lacking in how dimensions of IA may be associated with SI in an ED sample, above and beyond the impact of eating pathology on SI. Thus, in a clinical ED sample, the present study sought to determine which IA dimensions predict the presence and severity of SI, above and beyond ED symptoms. Participants (N = 102) completed a clinical interview assessing SI and self-report assessments including the Multidimensional Assessment of Interoceptive Awareness (MAIA). Results demonstrated that patients with current SI reported greater ED psychopathology, lower MAIA Attention Regulation, MAIA Self-Regulation, and MAIA Trusting scores compared to patients without SI. Higher ED psychopathology and lower MAIA Attention Regulation, Self-Regulation, and Trusting subscale scores were all significantly associated with the presence of SI. However, only low MAIA Trusting scores predicted the presence of SI, above and beyond covariates (age, depression, and eating pathology). No MAIA subscales were correlated with the severity of SI. Consistent with previous research, results suggest low MAIA Trusting scores may be associated with SI in ED samples and highlight the need for future research on mechanisms of these associations.

Abstract
To perform repeated measurements in clinical practice without putting unnecessary strain on patients, short instruments are needed. The Brief Self-Report Measure of Agitation (BAM) is a short measure assessing agitation, which has been associated with suicidal ideation and behavior. However, its reliability and validity have not been examined in an independent sample. A non-clinical sample of N = 429 participants aged between 18-81 (M = 27.36, SD = 9.67; 82.3% female) was surveyed online. A confirmatory factor analysis was conducted and reliability was investigated. The validity of the BAM was examined by calculating correlations and an ANOVA for differences in BAM scores between subgroups. BAM items significantly loaded onto one factor (factor loadings: ≥ .62) and the measure was found to have good reliability (Cronbach's α = .83) and convergent/discriminant validity. Participants with recent suicidal ideation and those with recent suicidal ideation and lifetime suicide attempts had significantly higher BAM scores than participants without suicidal ideation/suicide attempt. Results indicate good validity and reliability for the measurement of agitation with the German version of the BAM in the present sample. Thereby, we introduce a brief instrument in German for repeated assessment of agitation in research and clinical practice.

Abstract
OBJECTIVE Research has established pairwise relationships between suicidal ideation (SI), low Body Trust, elevated agitation, and eating disorders, but knowledge of how these aspects relate in a single model is lacking. This study tested an indirect pathway with low Body Trust relating to severity of SI via agitation in a clinical eating disorder sample. METHOD Participants (N = 319; 92.8% female; 93.4% Caucasian; mean age 21.8 years) were adults currently receiving specialized eating disorder treatment (44.3% intensive outpatient or higher level-of-care) who completed online self-report measures of study variables. The PROCESS macro was utilized to test proposed pathways. RESULTS Low Body Trust was significantly directly associated with increased severity of current SI, both before (B = -.89, p < .001) and after (B = -.51, p = .001) accounting for the indirect effect through agitation, also significant (B = -.37, SE = .06, CI -.52 to -.26). DISCUSSION Perception of the body as unsafe may be related to agitation, and this intolerable sensation of trapped arousal could contribute to a desire to die. Future work should investigate these relationships prospectively to determine the relevance of Body Trust for assessment and treatment of suicide-related factors among individuals with eating disorders.

Abstract
Interoceptive awareness (IA), or the awareness of internal body states, is known to be impaired in individuals with eating disorders (EDs); however, little is understood about how IA and ED symptoms are connected. Network analysis is a statistical approach useful for examining how symptoms interrelate and how comorbidities may be maintained. The present study used network analysis to (1) test central symptoms within an IA-ED network, (2) identify symptoms that may bridge the association between IA and ED symptoms, and (3) explore whether central and bridge symptoms predict ED remission at discharge from intensive treatment. A regularized partial correlation network was estimated in a sample of 428 adolescent (n = 187) and adult (n = 241) ED patients in a partial hospital program. IA was assessed using items from the Multidimensional Assessment of Interoceptive Awareness, and ED symptoms were assessed using items from the Eating Disorder Examination-Questionnaire. Central symptoms within the network were strong desire to lose weight, feeling guilty, and listening for information from the body about emotional state. The most central symptom bridging IA and ED symptoms was (not) feeling safe in one's body. Of the central symptoms, greater desire to lose weight predicted lower likelihood of remission at treatment discharge. Bridge symptoms did not significantly predict remission. Body mistrust may be a mechanism by which associations between IA and EDs are maintained. Findings suggest targeting central and bridge symptoms may be helpful to improve IA and ED symptoms.

Abstract
Research has linked agitation and low body trust to suicidal thoughts and behaviors. We investigated a pathway with agitation accounting for the relationship between body trust and suicidality. 511 individuals recruited via MTurk (Study 1) and 167 undergraduate students (62.9% with suicide attempt history) (Study 2) completed measures of study variables. For ideation, the proposed pathway was significant across samples, as was a pathway with agitation predicting and body trust mediating. In Study 1, agitation explained the relationship between body trust and attempt history. In Study 2, neither independent variable was related to attempt history. Results suggest body trust is independently associated with suicidal ideation. Results were discrepant regarding suicide attempt history, necessitating future studies.
