“…For researchers, distilling particular elements shared between autism and other conditions associated with NSSI would be valuable. Poor interoceptive awareness, for instance, is shared by people with eating disorders [110], autistic people [111], and self-harmers and people who report suicide ideation or attempts [112]. In this study, suicide-attempters were less likely to ignore or distract themselves from painful sensations and were less able to regulate distress by paying attention to bodily sensations [112].…”

Background: Autistic individuals without intellectual disability are at heightened risk of self-injury, and appear to engage in it for similar reasons as non-autistic people. A wide divergence of autistic perspectives on self-injury, including those who frame it as a helpful coping mechanism, motivate investigating the link between self-injury, suicide ideation, and attempts which has been reported in typically developing individuals. Method: One hundred three autistic participants completed the Non-Suicidal Self-Injury Assessment Tool (NSSI-AT), the Suicide Behaviors Questionnaire (SBQ-R), and the Interpersonal Social Evaluation List (ISEL-12) across two online studies. Logistic regression was conducted to predict self-harming status via responses to questions on suicidality, and to predict whether certain self-injurious behaviors, including cutting, were especially associated with suicide ideation and attempts. Non-parametric correlation analysis examined relationships between suicide ideation/ attempts and other variables that might characterize self-harmers especially at risk of suicidality. These included perceived access to social support, purposes or reasons for self-injury, the number of different self-injurious behaviors engaged in, the duration and lifetime incidence of self-injury, and the individual's feelings about their self-injury. Results: While self-injuring status was significantly predicted by responses to a question on suicide ideation and attempts, there was no relationship between suicide ideation/attempts and a participant's personal feelings about their self-injury. The method of cutting was also predicted by suicide ideation and attempts, though other methods common in autistic people were at borderline significance. Use of self-injury for the regulation of low-energy emotional states like depression, for self-punishment or deterrence from suicide, and for sensory stimulation, was associated with suicide ideation and attempts, as was the number of self-injurious behaviors engaged in. There was no significant relationship between suicide ideation/attempts and the duration and lifetime incidence of self-injury or social support. Conclusions: These preliminary data suggest that while individuals might frame their self-injury as a positive or neutral thing, there remains a concerning relationship between self-injury and suicidality which exists regardless of individual feelings on self-injury. This is consistent with the theoretical perspective that self-injury can be a "gateway" through which individuals acquire capability for lethal suicidal behaviors. The data highlight that particular methods (cutting) and reasons for self-injury may be of significant concern, but this information, which might be of extreme value for clinicians, requires further investigation and validation.

“…This possible primacy of DIF in predicting overeating has recently been supported by results from experimental studies. They have shown that DIF may foster the tendency to misinterpret the visceral sensations related to hunger and satiety, thus leading to maladaptive eating patterns (Ernst et al, ; Herbert, Herbert, & Pollatos, ; Jenkinson, Taylor, & Laws, ; Kano, Hamaguchi, Itoh, Yanai, & Fukudo, ; Nakao, Barsky, Kumano, & Kuboki, ; Scarpazza, Làdavas, & di Pellegrino, ). Recent neuroscientific findings suggest that obesity may be associated with hypersensitivity to interoceptive signals of hunger and insensitivity to interoceptive signals of satiety (Simmons & DeVille, ).…”

Objective To investigate whether obese patients with binge eating (BE) have higher alexithymic features; to explore the different relationships between psychological features (alexithymia, depression, and anxiety) and BE. Method Three hundred sixty one obese BE‐patients were evaluated for alexithymia, psychological distress, and BE. Alexithymia was measured with the 20‐item Toronto Alexithymia Scale (TAS‐20); BE was assessed with the BE Scale (BES), and depression and anxiety symptoms were evaluated with the Hospital Anxiety and Depression Scale (HADS). Results Patients with BE reported significantly higher TAS‐20 total scores than those without BE (p < .001). The SEM analysis showed that the difficulty in identifying feelings (DIF) and difficulty in describing feelings (DDF) components of alexithymia affected BE along different pathways. DIF was found as a major factor influencing altered eating both directly (p = .20*) and above all through the mediation of psychological distress (p = .19***), whereas DDF affected BE only through psychological distress at a lesser extent (p = .09**). Discussion Alexithymic difficulties in affective awareness may play an important role in the onset and maintenance of BE, especially when patients experienced anxiety and depression symptoms. Clinicians involved in the management of obesity should address the combination of alexithymic traits and emotional distress by planning effective client‐focused interventions.

“…One previous study has used a heartbeat discrimination task, finding no differences between people with AN and HC (15). By contrast, research on interoceptive sensibility in AN consistently suggests that people with AN self-report a lack of confidence in their ability to detect their internal stimuli compared to HC (16). It should be noted that these previous interoceptive sensibility studies have primarily used the interoceptive subscale of the Eating Disorder Inventory (EDI) (17).…”

Interoception in Anorexia Nervosa: Exploring Associations With Alexithymia and Autistic Traits

2020

Background: Previous research on whether interoception is altered in anorexia nervosa (AN) using the heartbeat tracking task has yielded inconsistent results. However, no previous research has examined whether interoception is associated with alexithymia and autistic traits in AN, conditions which are more prevalent in this population and thought to be related to performance in this task. The aim of this study was to explore whether altered interoception in AN is associated with alexithymia and autistic traits. Methods: We assessed interoceptive accuracy using the heartbeat tracking task in n = 37 people with AN, and n = 37 age and gender matched healthy controls (HC), and explored within the AN group if interoceptive accuracy was related to self-rated alexithymia or autistic traits. We also assessed self-reported interoceptive ability, and the relationship between subjective and actual performance. Results: Heartbeat tracking task performance was not found to be altered in the AN group compared to the HC group. However, confidence ratings in task performance in the AN group were lower compared to the HC group. Unlike the HC group, confidence ratings in the AN group did not correlate with task performance. Within the AN group there was no relationship between interoceptive accuracy, alexithymia, and autistic traits, after controlling for the potential confounders of anxiety and depression. There was a relationship between confidence ratings and illness severity in the AN group. Conclusion: The results found no differences between heartbeat tracking task performance in people with AN compared to HC. There was no association between task performance, alexithymia and autistic traits in AN. Results do suggest that people with AN exhibit lowered confidence in their task performance, and that they may lack insight into this performance compared to HC. The findings are discussed in the context of potential significant limitations of the heartbeat tracking task, with recommendations for future research into interoception in AN.
