Children aged 5-13 years show adult-like disgust avoidance, but not proto-nausea.

Disgust is a vital emotion in the avoidance of illness. Human adults across cultures show disgust towards sources of potential contamination or pathogens, and elect to avoid their ingestion or even to look at them. Stomach rhythms appear to play an important role: disgust reduces normogastric power, and the pharmacological normalisation of gastric state reduces disgust avoidance. Human children are remarkably slow to develop disgust as measured by self-report and facial expressions. Here, we investigate whether disgust-induced avoidance (measured using eye tracking) and changes in gastric rhythm (measured using electrogastrography) exist in children aged 5 to 13 years (N = 45). We found that children in this bracket showed oculomotor avoidance of disgusting stimuli in a preferential-looking task, similar to adult samples in previous research. However, in contrast to adult samples in previous research, children did not show an attenuation in normogastric power. These findings could suggest that avoidance behaviour precedes gastric involvement during disgust. This would support the idea that children initially respond to parental modelling: parents set (and enforce) the social norm of disgust avoidance, and children initially conform and only later do they internalise disgust as an interoceptive signal. Alternatively, the employed stimuli could have been potent enough to induce oculomotor avoidance, but not a gastric response. Research is slim in this area, and future work should focus on elucidating the role of the stomach in disgust, and on longitudinal studies of disgust development from childhood to adolescence.

Hunger, Satiety, and Their Vulnerabilities.

The psychological states of hunger and satiety play an important role in regulating human food intake. Several lines of evidence suggest that these states rely upon declarative learning and memory processes, which are based primarily in the medial temporal lobes (MTL). The MTL, and particularly the hippocampus, is unusual in that it is especially vulnerable to insult. Consequently, we examine here the impact on hunger and satiety of conditions that: (1) are central to ingestive behaviour and where there is evidence of MTL pathology (i.e., habitual consumption of a Western-style diet, obesity, and anorexia nervosa); and (2) where there is overwhelming evidence of MTL pathology, but where ingestive behaviour is not thought central (i.e., temporal lobe epilepsy and post-traumatic stress disorder). While for some of these conditions the evidence base is currently limited, the general conclusion is that MTL impairment is linked, sometimes strongly, to dysfunctional hunger and satiety. This focus on the MTL, and declarative learning and memory processes, has implications for the development of alternative treatment approaches for the regulation of appetite.

Effects of One-to-One Trauma Center Trauma-Sensitive Yoga Sessions on Psychological Symptoms and Interoception over 6 Months.

Posttraumatic stress disorder (PTSD) is a serious health condition that adversely affects the mind and body. Current first-line treatment for PTSD tends to focus on the mind and overlook the impacts of trauma on the body. Trauma Center Trauma-Sensitive Yoga (TCTSY) is an evidence-based adjunctive therapy for complex trauma and PTSD that uses a body-based approach to trauma healing. Although designed to be used in group or individual contexts, previous studies have focused only on TCTSY facilitated in groups. The present study examined the effects of one-to-one TCTSY (i.e., one participant receiving TCTSY services, not in a group TCTSY context) on anxiety, depression, posttraumatic stress, interoception, substance use, and sleep over time. Using an observational approach, all certified TCTSY facilitators received the study invitation to share with clients who were enrolled in one-to-one TCTSY services. Ten clients participated in the study across four countries (women n = 8; mean age 44.80 ± 11.91; PTSD diagnosis n = 9). Clients completed Qualtrics surveys at TCTSY sessions in June-December 2022. Linear mixed-model analyses found that anxiety, depression, posttraumatic stress symptoms, attention regulation, self-regulation, and body listening significantly improved over time. There were no significant changes in sleep or substance use from pre- to post-study. TCTSY is a somatic approach for managing trauma symptoms and enhancing interoceptive awareness. Extensions of the present study are warranted to further understand the effects of one-to-one TCTSY for trauma care.

Linking the inner and outer mental representations of the body to social cognition skills: A systematic review and meta-analysis.

An interesting interpretation of embodiment highlights the critical role of mental body representations (BR), including motor, somatosensory, and interoceptive formats, for social cognition. However, the nature of this relationship is still debated at the empirical level, with various studies arriving at different conclusions. Here, we present a systematic review and meta-analysis aimed to summarize data from 3466 participants in 21 studies to provide a more comprehensive understanding of the relationship between inner and outer BR and social cognition. We focused on two core social cognition aspects: empathy and Theory of Mind (ToM). Concerning the inner BR, our meta-analytic findings reveal a significant correlation between specific interoceptive dimensions (i.e., interoceptive sensibility and accuracy) and social cognition, which was stronger for empathy than ToM. Conversely, although further research is needed, functional BR that mainly involve the outer body processing (i.e., nonaction-oriented BR) may show positive links with ToM. These findings point to specific interactions between BR and social cognition skills, supporting multi-faceted and embodied social cognition models. However, we also identified critical knowledge gaps and highlighted the need for further investigation to deepen our theoretical understanding of these relationships and their implications for clinical practice.

States of consciousness and interoceptive hypersensibility: A study in patients with insomnia disorder.

This exploratory study aimed to investigate the relationship between interoceptive sensibility and quality of consciousness in individuals with insomnia disorder, in order to understand how the modulation of internal states may contribute to modifying the experience of consciousness during sleep difficulties. A total of 37 patients with insomnia disorder (mean age = 46.05 ± 18.16) and 41 healthy good sleepers (mean age = 50.2 ± 12.99) underwent a psychometric sleep and interoceptive sensibility assessment, using Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), and Multidimensional Assessment of Interoceptive Awareness (MAIA). Moreover, patients with insomnia disorder also completed a quality of consciousness evaluation, using the Phenomenology of Consciousness Inventory (PCI). Patients with insomnia disorder exhibited heightened interoceptive sensibility, particularly in noticing body sensations (p < 0.0001) and emotional awareness (p = 0.032), along with diminished abilities in attention regulation (p = 0.040), not-worrying (p = 0.001), and trusting (p = 0.002). Furthermore, correlations between interoceptive sensibility and multiple aspects of the consciousness state during the insomnia night were identified. Specifically, higher emotional awareness was linked to a 2.49-fold increase in the likelihood of subjectively experiencing altered consciousness states during insomnia. The study sheds light on the relationship between interoceptive sensibility and the subjective state of consciousness during insomnia, emphasising the importance of exploring and considering interoception as part of the therapeutic process for insomnia disorder. Given the exploratory nature of the study and the increased risk of type-I error from numerous correlations, the results should be interpreted with caution. Further research is needed to validate and confirm their robustness.

Cardiac cycle modulates social pain.

Social pain is a painful feeling evoked by social rejection, exclusion, or the loss of other important people. Previous research suggests that physical pain is reduced by increased signals from baroreceptors that monitor blood pressure. This pre-registered study investigated whether social pain is attenuated by increased baroafferent signals, as observed in physical pain. Given that baroafferent signals increase during cardiac systole and decrease during diastole, we hypothesized that feelings of pain induced by social rejection would be lower when exclusion events are presented at the cardiac systole than when they are presented at the diastole. Participants completed the cyberball task, a computerized ball-tossing game involving two other players. In the rejection condition, the ball was rarely thrown to the participant, while the other players kept tossing it to each other. Throws between other players were defined as exclusion events and were presented either at the cardiac systole (a systole condition) or at the diastole (a diastole condition). We found that exclusion events evoked significantly less social pain in the systole condition than in the diastole condition. Furthermore, the effects of cardiac cycle were more pronounced in participants with higher heart rate variability than those with lower heart rate variability. Our results suggest that cardiac afferent signals contribute not only to physical pain but also to social pain.

Interoceptive training with real-time haptic versus visual heartbeat feedback.

The perception of signals from within the body, known as interoception, is increasingly recognized as a prerequisite for physical and mental health. This study is dedicated to the development of effective technological approaches for enhancing interoceptive abilities. We provide evidence of the effectiveness and practical feasibility of a novel real-time haptic heartbeat supplementation technology combining principles of biofeedback and sensory augmentation. In a randomized controlled study, we applied the developed naturalistic haptic feedback on a group of 30 adults, while another group of 30 adults received more traditional real-time visual heartbeat feedback. A single session of haptic, but not visual heartbeat feedback resulted in increased interoceptive accuracy and confidence, as measured by the heart rate discrimination task, and in a shift of attention toward the body. Participants rated the developed technology as more helpful and pleasant than the visual feedback, thus indicating high user satisfaction. The study highlights the importance of matching sensory characteristics of the feedback provided to the natural bodily prototype. Our work suggests that real-time haptic feedback might be a superior approach for strengthening the mind-body connection in interventions for physical and mental health.

Exploring the impact of maternal early life adversity on interoceptive sensibility in pregnancy: implications for prenatal depression.

PURPOSE: Pregnancy is a sensitive period of development in adult life characterized by massive changes in physical, emotional, and cognitive function. Such changes may be adaptive, e.g., facilitating adjustment to physical demands, but they may also reflect or contribute to risks inherent to this stage of life, e.g., prenatal depression. One cognitive ability that may undergo change during pregnancy and contribute to mental wellness is interoception - the ability to perceive, integrate, and model sensory information originating from the body. Strong interoceptive abilities are associated with lower rates of depression in non-pregnant adult populations, and interoception is generally weaker in individuals at higher risk for depression, for example, exposure to early life adversity (ELA). In the present online, cross-sectional study, we investigated whether interoception in pregnant women differed based on histories of ELA, in ways that increased their relative risk for prenatal depression symptoms. METHODS: The pregnant individuals were in the second trimester of their first pregnancy and were compared to a group of nulliparous, non-parenting women. RESULTS: Previous exposure to ELA significantly moderated pregnancy-related differences in self-reported interoception (interoceptive sensibility). A further moderated-mediation analysis revealed that the extent to which interoceptive sensibility buffered against depressive symptoms was conditional on ELA exposure, suggesting more ELA is associated with lower interoceptive sensibility during pregnancy, which increased prenatal depression risk. CONCLUSIONS: Together this work suggests that levels of interoception during pregnancy are sensitive to previous adversity exposure. It also suggests that interoceptive-focused interventions for preventing/treating prenatal depressive symptoms in high-risk women may be worth exploring.

Feldenkrais method and clinical psychology: A systematic literature review exploring the potential of Feldenkrais Method in psychiatric care.

BACKGROUND: In psychotherapy, physical exercise has gained recognition and extensive research attention, displaying promise in various mental health conditions. Practices such as yoga, tai chi, and the Feldenkrais Method® (FM) have also emerged as effective mental health interventions. OBJECTIVES: This systematic literature review (SLR) explores the applicability of FM, a somatic practice, in psychiatric care and emotional regulation, as it emphasizes the interplay between bodily sensations, action patterns, and cognitive processes. METHODS: Following PRISMA guidelines, a systematic search was conducted across selected databases from 2000 to 2022, identifying 14 articles, including randomized controlled trials, cohort studies, narrative papers, and SLRs. Thematic analysis was conducted. RESULTS: The findings indicate global FM adoption, primarily in studies related to pain conditions, musculoskeletal disorders, and neurological disorders. Various measures were used, covering quality of life, psychological dimensions, self-image, self-efficacy, mindfulness, and interoception. However, direct application of FM in psychiatric care remains limited, with few studies addressing psychological issues. This review calls for more comprehensive investigations of FM's potential in psychiatric contexts, advocating precise measures and a dimensional approach to assessing psychological outcomes. CONCLUSION: Further research is needed to explore the application of FM in psychiatric care. While existing research suggests potential benefits, especially in enhancing body awareness and emotional regulation, robust studies are necessary to establish its effectiveness in treating specific mental health conditions. This review serves as the foundation for future research into the potential role of FM in enhancing psychiatric care and emotional well-being.

Blind individuals' enhanced ability to sense their own heartbeat is related to the thickness of their occipital cortex.

Blindness is associated with heightened sensory abilities, such as improved hearing and tactile acuity. Moreover, recent evidence suggests that blind individuals are better than sighted individuals at perceiving their own heartbeat, suggesting enhanced interoceptive accuracy. Structural changes in the occipital cortex have been hypothesized as the basis of these behavioral enhancements. Indeed, several studies have shown that congenitally blind individuals have increased cortical thickness within occipital areas compared to sighted individuals, but how these structural differences relate to behavioral enhancements is unclear. This study investigated the relationship between cardiac interoceptive accuracy and cortical thickness in 23 congenitally blind individuals and 23 matched sighted controls. Our results show a significant positive correlation between performance in a heartbeat counting task and cortical thickness only in the blind group, indicating a connection between structural changes in occipital areas and blind individuals' enhanced ability to perceive heartbeats.

Emotional activation in a cognitive behavioral setting: extending the tradition with embodiment.

The neuroscience-based concept of "embodied cognition" or "embodiment" highlights that body and psyche are closely intertwined, i.e., effects of body and psyche are bidirectional and reciprocal. This represents the view that cognitive processes are not possible without the direct participation of the body. Traditional Cognitive Behavioral Therapy (CBT) addresses emotional processes on a conceptual level (dysfunctional thoughts, beliefs, attributions, etc.). However recent findings suggest that these processes already start at the level of bodily sensations. This opens up a way of working in therapy that includes the level of bodily sensations, where the development of emotional meaning is supported by bottom-up processes. Bidirectionality of embodiment can be effectively exploited by using body postures and movements associated with certain emotions, which we refer to as embodiment techniques, to deepen the physical experience of poorly felt emotions and support the valid construction of emotional meaning. This embodied approach offers several advantages: Prelinguistic or hard-to-grasp aspects can be identified more easily before being processed verbally. It is also easier to work with clients who have limited access to their emotions. Thus, in this paper we describe a new embodied CBT approach to working on the dysfunctional schema, which is based on three modules: body focus, emotional field, and interaction focus. In addition, using specific zones in the space of the therapy-room allows the embodiment of problematic interactions, as well as of power and powerlessness, closeness and distance, etc. Directly experiencing these processes on one's own body in the protected space of therapy allows faster and deeper insights than would be possible with conversations alone. Finally, the vitalizing power of emotions is used to create coherent action plans and successful interactions. This working method is illustrated by means of a case from practice.

The Role of Emotion Regulation and Awareness in Psychosocial Stress: An EEG-Psychometric Correlational Study.

BACKGROUND: In stressful situations, to overcome unpleasant emotions, individuals try to manage stress through emotion regulation strategies such as cognitive reappraisal, interoception, and mindfulness. METHOD: 26 healthy adults underwent a modified version of the Trier Social Stress Test (named the Social Stress Test, SST) while their electrophysiological (EEG) activity was monitored. Participants also completed self-report questionnaires prior to this, including the Five-Facet Mindfulness Questionnaire (FFMQ), Multidimensional Assessment of Interoceptive Awareness (MAIA), Emotional Regulation of Others and Self (EROS), and the Interpersonal Reactivity Index (IRI). Three brain regions of interest (ROIs) were considered in the EEG data processing: frontal, temporo-central, and parieto-occipital. Correlational analyses were performed between psychometric scales and EEG band power spectral values for each ROI. RESULTS: The results showed positive correlations between interoceptive awareness, mindfulness, and high-frequency EEG bands (beta, alpha, gamma) over frontal ROI, indicating enhanced cognitive processing and emotional regulation. Conversely, emotion regulation and empathy measures correlated positively with low-frequency EEG bands (delta, theta), associated with improved social cognition and top-down regulatory processes. CONCLUSIONS: These findings suggest that EEG correlations of the stress response are connected to emotion regulation mechanisms, emphasizing the importance of body state awareness in managing stress and emotions for overall well-being and quality of life.

Cybernetic Principles in Psychophysiology: Their Significance and Conclusions for Palliative Care.

Palliative care is dedicated to terminally ill patients with advanced disease, regardless of diagnosis, under the overarching premise of optimizing quality of life. This narrative review examines the extent to which principles of cybernetics and psychophysiology underlie this approach. Psychophysiology researches the physiological equivalents of psychological states and traits such as activation and individual reactivity, the interoception and the personal characteristics. Cybernetics specifies these principles, which are possible by understanding terms such as "psychophysiology" or "cybernetics" or "self-organization/autopoiesis". The meaning of these terms for palliative care can also be elucidated in relation to the terms "biofeedback", "consciousness", "pain", and "anxiety". The common themes of cybernetics and psychophysiology are environment, subjectivity, personality characteristics, the difference between time scale separation in cybernetic systems, and real-time procedures in environment and rhythm. These lead to special therapies based on psychophysiology, such as consciousness training. The concepts of quality of life, causality, the biopsychosocial model, therapy, and autonomy are examined as palliative care concepts. The equivalents can be described from the perspective of cybernetics. For some palliative care-related terms, cybernetic thinking is already present (quality of life, autonomy, symptom control), while for others, it is not (biopsychosocial). Cybernetic terms (complexity, stability, identity, rhythm) are still used to a lesser extent in palliative care. Terms like genetic basis are common in cybernetics and psychophysiology to explain the identity of the subject in transition. Identity, on the other hand, is the basis of the concept of dignity in palliative care. Psychophysiology investigates disturbances like pain and psychological illnesses, which are also present in palliative care. Psychophysiology, cybernetics, and palliative care have subjectivity and resources in common. Therapies based on cybernetic principles of psychophysiology can also be used for symptom control in palliative care in the oncology setting.

Heart-Brain Axis: A Narrative Review of the Interaction between Depression and Arrhythmia.

Arrhythmias and depression are recognized as diseases of the heart and brain, respectively, and both are major health threats that often co-occur with a bidirectional causal relationship. The autonomic nervous system (ANS) serves as a crucial component of the heart-brain axis (HBA) and the pathway of interoception. Cardiac activity can influence emotional states through ascending interoceptive pathways, while psychological stress can precipitate arrhythmias via the ANS. However, the HBA and interoception frameworks are often considered overly broad, and the precise mechanisms underlying the bidirectional relationship between depression and arrhythmias remain unclear. This narrative review aims to synthesize the existing literature, focusing on the pathological mechanisms of the ANS in depression and arrhythmia while integrating other potential mechanisms to detail heart-brain interactions. In the bidirectional communication between the heart and brain, we emphasize considering various internal factors such as genes, personality traits, stress, the endocrine system, inflammation, 5-hydroxytryptamine, and behavioral factors. Current research employs multidisciplinary knowledge to elucidate heart-brain relationships, and a deeper understanding of these interactions can help optimize clinical treatment strategies. From a broader perspective, this study emphasizes the importance of considering the body as a complex, interconnected system rather than treating organs in isolation. Investigating heart-brain interactions enhance our understanding of disease pathogenesis and advances medical science, ultimately improving human quality of life.

Unveiling the interoception impairment in various major depressive disorder stages.

BACKGROUND: The intricate pathophysiological mechanisms of major depressive disorder (MDD) necessitate the development of comprehensive early indicators that reflect the complex interplay of emotional, physical, and cognitive factors. Despite its potential to fulfill these criteria, interoception remains underexplored in MDD. This study aimed to evaluate the potential of interoception in transforming MDD's clinical practices by examining interoception deficits across various MDD stages and analyzing their complex associations with the spectrum of depressive symptoms. METHODS: This study included 431 healthy individuals, 206 subclinical depression individuals, and 483 MDD patients. Depressive symptoms and interoception function were assessed using the PHQ-9 and MAIA-2, respectively. RESULTS: Interoception dysfunction occurred in the preclinical phase of MDD and further impaired in the clinical stage. Antidepressant therapies showed limited efficacy in improving interoception and might damage some dimensions. Interoceptive dimensions might predict depressive symptoms, primarily enhancing negative thinking patterns. The predictive model based on interoception was built with random split verification and demonstrated good discrimination and predictive performance in identifying MDD. CONCLUSIONS: Early alterations in the preclinical stage, multivariate associations with depressive symptoms, and good discrimination and predictive performance highlight the importance of interoception in MDD management, pointing to a paradigm shift in diagnostic and therapeutic approaches.

Heartbeat-related spectral perturbation of electroencephalogram reflects dynamic interoceptive attention states in the trial-by-trial classification analysis.

Attending to heartbeats for interoceptive awareness initiates distinct electrophysiological responses synchronized with the R-peaks of an electrocardiogram (ECG), such as the heartbeat-evoked potential (HEP). Beyond HEP, this study proposes heartbeat-related spectral perturbation (HRSP), a time-frequency map of the R-peak locked electroencephalogram (EEG), and explores its characteristics in identifying interoceptive attention states using a classification approach. HRSPs of EEG brain components specified by independent component analysis (ICA) were used for the offline and online classification of interoceptive states. A convolutional neural network (CNN) designed specifically for HRSP was applied to publicly available data from a binary-state experiment (attending to self-heartbeats and white noise) and data from our four-state classification experiment (attending to self-heartbeats, white noise, time passage, and toe) with diverse input feature conditions of HRSP. From the dynamic state perspective, we evaluated the primary frequency bands of HRSP and the minimal number of averaging epochs required to reflect changing interoceptive attention states without compromising accuracy. We also assessed the utility of group ICA and models for classifying HRSP in new participants. The CNN for trial-by-trial HRSP with actual R-peaks demonstrated significantly higher classification accuracy than HRSP with sham, i.e., randomly positioned, R-peaks. Gradient-weighted class activation mapping highlighted the prominent role of theta and alpha bands between 200-600 ms post-R-peak-features absent in classifications using sham HRSPs. Online classification benefits from employing a group ICA and classification model, ensuring reliable accuracy without individual EEG precollection. These results suggest HRSP's potential to reflect interoceptive attention states, proposing transformative implications for clinical applications.

Body Evaluation and Body Ownership in Patients with Inflammatory Bowel Disease: the Role of Interoceptive Sensibility and Childhood Maltreatment.

OBJECTIVE: Inflammatory bowel diseases (IBD) are accompanied by symptoms that can vastly affect patients' representations of their bodies. The aim of this study was to investigate alterations in body evaluation and body ownership in IBD and their link to interoceptive sensibility, gastrointestinal-specific anxiety, and history of childhood maltreatment. METHODS: Body evaluation and ownership was assessed in 41 clinically remitted patients with IBD and 44 healthy controls (HC) using a topographical self-report method. Interoceptive sensibility, gastrointestinal-specific anxiety and a history of childhood maltreatment were assessed via self-report questionnaires. RESULTS: Patients reporting higher interoceptive sensibility perceived their bodies in a more positive manner. Higher gastrointestinal-specific anxiety was linked to a more negative body evaluation particularly of the abdomen in patients with IBD. Childhood maltreatment severity strengthened the positive association between interoceptive sensibility and body ownership only in those patients reporting higher trauma load. CONCLUSION: Altered body representations of areas associated with abdominal pain are linked to higher symptom-specific anxiety and lower levels of interoceptive sensibility in IBD. Particularly in patients with a history of childhood maltreatment, higher levels of interoceptive sensibility might have a beneficial effect on the patients' sense of body ownership.

When the body fosters empathy: The interconnectivity between bodily reactivity, meditation, and embodied abstract concepts.

Empathy is a fundamental social ability that allows humans to infer others' emotions and intentions. Empathy is thought to be rooted in bodily sensations coming from the autonomic nervous system. In parallel, the functionality and perceptions coming from the autonomic nervous system could be improved by practicing activities that involve mind-body interactions, such as meditation. Furthermore, perceptions from the autonomic nervous system are thought to be important in the embodiment of abstract concepts. Consequently, in the current study, we collected data online from 581 participants and explored the associations between levels of empathy and (1) the practice of meditation, music, and sports; (2) the impact of self-report measures on bodily awareness and reactivity; and (3) the embodiment of abstract concepts in interoception. In line with previous studies, Meditators were found to have higher empathy scores than Non-Meditators. In addition, lower levels of autonomic reactivity in organs above the diaphragm were associated with higher empathy. Finally, we also observed that empathy was positively associated with interoceptive components of abstract concepts in those participants with high autonomic reactivity. Taken together, the results suggest that meditation practice and having low autonomic reactivity are associated with empathy, arguably through the downregulation of autonomic responses. Implications for mind-body interaction in meditation and its role in promoting empathy are discussed.

Interoceptive awareness in a Southeastern US college sample: validation of the multidimensional assessment of interoceptive awareness - version 2.

OBJECTIVE: The Multidimensional Assessment of Interoceptive Awareness, version 2 (MAIA-2) is a commonly utilized self-report instrument to assess individuals' ability to perceive bodily sensations. The MAIA-2 has displayed variable psychometric properties across samples. Thus, we examine the psychometric properties of the MAIA-2 in a Southeastern United States college sample. PARTICIPANTS: Our studies consisted of 710 (study 1) and 66 (study 2) college students. METHODS: Study 1 used a cross-sectional research design where we investigated the factor structure, and measurement invariance (e.g., measured similarly across genders). Study 2 examined the test-retest reliability across a three-week period. RESULTS: The MAIA-2 displayed adequate to good internal consistencies and factor loadings, strict invariance, and questionable temporal stability. CONCLUSION: The MAIA-2 demonstrates adequate psychometric properties in this college sample that were similar to the original MAIA sample characteristics. Contextual and cultural factors may influence the subjective experience of interpreting bodily sensations.
