Body awareness: construct and self-report measures

Body awareness disturbances in patients with low back pain: a systematic review

BACKGROUND

The pain-neuroscience literature has recently emphasized body perception or awareness. Impaired body perception results have been reported in many different chronic pain problems. Studies have reported that individuals with low back pain (LBP) also have body perception disturbances related to the lumbar spine.

OBJECTIVES

This review aimed to determine the evidence that body awareness alterations in individuals with LBP.

DESIGN

Systematic review.

METHOD

Studies were searched in PubMed, Cochrane Library, and Pedro databases up to January 2021. Each database was searched independently, according to a specific iteration research string. The protocol record of the systematic review was entered into the PROSPERO system.

RESULTS

Nine studies were included in this research. We found evidence to support more perceptual impairments in patients with LBP than healthy counterparts. In addition, the results of the studies showed an association between disrupted body awareness and pain severity, pain catastrophizing, and disability.

CONCLUSIONS

Body perception disturbances in LBP seem to be a promising path that needs to be further explored, with the ultimate goal of developing treatment contents targeting body awareness as a more comprehensive and valid evaluation and therapeutic method.

Interoceptive bodily awareness in patients seeking pain relief with osteopathic manipulative treatment: an observational cohort pilot study

CONTEXT

Interoceptive bodily awareness (IBA) is one's attentional focus on and relationship with comfortable and uncomfortable (e.g., pain) internal body sensations. Integrating IBA into research on osteopathic manipulative treatment (OMT) is growing, both as an outcome and predictor of treatment outcomes; however, it has yet to be studied in a clinical setting.

OBJECTIVES

We aimed to conduct a pilot study to measure IBA, with the Multidimensional Assessment of Interoceptive Awareness (MAIA), in patients seeking OMT for pain, and to test if OMT exposure may be associated with higher IBA as measured by the MAIA. The primary outcome was the change in MAIA scores, and the secondary outcomes were reduction in pain intensity, reduction in pain interference, and increase in participants' perception of change post-OMT.

METHODS

A convenience sample was recruited from individuals presenting for OMT appointments at a College of Osteopathic Medicine OMT teaching clinic. Participants were recruited into our single-arm observational cohort study (n=36), and categorized into one of two groups, OMT-naïve (n=19) or OMT-experienced (n=17), based on prior exposure to OMT. We measured MAIA scores and clinical pain-related outcomes prior to, immediately after, and at 1 and 3 weeks after a usual-care OMT session in the clinic. Covariates including experience with mind-body activities, non-OMT body work, and physical and emotional trauma were also collected to explore potential relationships. We utilized t tests to compare MAIA scores and pain outcomes between groups and across time points. Stepwise regression models were utilized to explore potential relationships with covariates.

RESULTS

The OMT-experienced group scored higher on the MAIA scales "Not-worrying" (p=0.002) and "Trusting" (p=0.028) at baseline. There were no significant changes in the MAIA scores before and after the single OMT session. Analysis of secondary outcomes revealed that all pain outcomes significantly decreased post-OMT (p<0.05), with the largest relative improvements in the acute pain and OMT-naïve subgroups, with diminishing effects over time.

CONCLUSIONS

Assessing IBA with MAIA in a clinical OMT setting is feasible. There were significant positive correlations between OMT exposure and two of the eight MAIA scales. Future studies are justified to further explore this relationship.

An Overview of the Bodily Awareness Representation and Interoception: Insights and Progress in the Field of Neurorehabilitation Research

In the last two decades, the scientific literature on so-called body representations has been increasing, and the notion of body awareness (BA) is particularly interesting for neurorehabilitation. In this article, we present results derived from recent studies on this representation, considering the different definitions and explicative models proposed as well as the empirical settings used to test it, providing an extensive overview of these issues. This article discusses the challenge of understanding how we integrate the sensory experiences of proprioception (knowing where our body is in space) and interoception (sensing internal bodily sensations, like hunger of thirst) with our perception of self. This is a difficult problem to analyze because our awareness of our body is inherently linked to our perspective, since the body is the means through which we interact with the world. Presenting the different viewpoints offered by recent theories on this concern, we highlighted that the neurorehabilitation and psychiatric settings offer two important fields useful for the study of BA because in them it is possible to analyze bodily representations by inducing/observing a controlled discrepancy between dysfunctional content and sensory inputs.

Personality systems interactions theory: an integrative framework complementing the study of the motivational and volitional dynamics underlying adjustment to chronic pain

In the endeavor to advance our understanding of interindividual differences in dealing with chronic pain, numerous motivational theories have been invoked in the past decade. As they focus on relevant, yet different aspects of the dynamic, multilevel processes involved in human voluntary action control, research findings seem fragmented and inconsistent. Here we present Personality Systems Interactions theory as an integrative meta-framework elucidating how different motivational and volitional processes work in concert under varying contextual conditions. PSI theory explains experience and behavior by the relative activation of four cognitive systems that take over different psychological functions during goal pursuit. In this way, it may complement existing content-related explanations of clinical phenomena by introducing a functional, third-person perspective on flexible goal management, pain acceptance and goal maintenance despite pain. In line with emerging evidence on the central role of emotion regulation in chronic pain, PSI theory delineates how the self-regulation of positive and negative affect impacts whether behavior is determined by rigid stimulus-response associations (i.e., habits) or by more abstract motives and values which afford more behavioral flexibility. Along with testable hypotheses, multimodal interventions expected to address intuitive emotion regulation as a central process mediating successful adaptation to chronic pain are discussed.

Investigating the effects of postural habits and awareness on early adolescent's internet addiction levels

OBJECTIVES

Early adolescence is a period of growth and development determined by the onset of puberty, during which important changes in psychological development and social roles occur. Excessive use of the internet, especially in adolescents in this period, causes health problems such as postural disorders, vision problems, sedentary life, and unbalanced nutrition. When the studies are analyzed, it is observed that postural disorders are observed in children and adolescents. This study was planned to investigate the effect of postural habits and awareness on the level of internet addiction in early adolescents.

METHODS

Physical characteristics of the participants (age, height, weight, gender, body mass index) were recorded. Duration and purpose of internet use and internet addiction were determined with the Young Internet Addiction Test-Short Form, body composition sensitivity level with the Body Awareness Questionnaire, and postural awareness with the Postural Habit and Awareness Scale.

RESULTS

There was a significant positive correlation between internet addiction and duration of internet use (r=0.466) (p=0.000). In addition, there was no relationship between internet usage time and body awareness (r=-0.117) (p=0.084) and postural awareness and habit (r=-0.017) (p=0.798). When internet addiction was compared with body awareness, a significant relationship was found in the opposite direction (r=-0.145) (p=0.031). When internet addiction was compared with postural awareness and habit, a positive relationship was found (r=0.190) (p=0.005).

CONCLUSIONS

Our study showed that internet addiction negatively affects body awareness, and does not affect postural habits, but positively affects postural awareness.

Vague sensations. About the background and consequences of discordance between actual and perceived physiological changes

Empirical evidence consistently shows that discordance, also called dissociation or discrepancy, between actual physiological (mainly visceral) events and their perceived counterparts is substantial. On the one hand, we typically do not perceive actual visceral events occurring in our bodies; on the other hand, sometimes we do perceive bodily changes that do not really take place. This narrative review presents the available empirical findings on the discordance, and summarizes possible explanations that approach the phenomenon from the viewpoint of evolution, cognitive development, and predictive processing. Also, the role of top-down factors, such as expectations and experiences is discussed. Finally, practically relevant consequences of the discordance are presented using the examples of mind-body practices, the placebo and nocebo phenomenon, and medically unexplained symptoms. It is concluded that the discordance between actual and perceived body changes can have a negative impact on health, mainly through issues with adherence and other behavioral factors. The existence of actual-perceived discordance should be taught and demonstrated in the elementary and high school, as well as in many areas of higher education.

Basolateral Amygdala Functional Connectivity in Alexithymia: Linking Interoceptive Sensibility and Cognitive Empathy

Emotions rely on bodily states, and perceiving the emotions of others depends on awareness of one's own emotional state. However, the intercorrelations among interoception, alexithymia, and empathy are not well understood, and the neural mechanisms behind this connection are also largely unknown. To address these issues, 297 college students participated in this study, completing measures of interoceptive sensibility (IS), empathy and alexithymia and undergoing resting-state fMRI scans. The functional connectivity of the amygdala was analysed to identify the neural substrates of alexithymia, and mediation analyses were conducted to examine the mediation effect of alexithymia and alexithymia-specific amygdala functional connectivity on the relationship between IS and empathy. The results showed that higher levels of IS were associated with increased cognitive empathy through weakened alexithymia. Functional connectivity analysis indicated that right basolateral amygdala (BLA)-left precuneus connectivity was negatively related to alexithymia, while right BLA-left precentral gyrus connectivity was positively related to alexithymia. Furthermore, right BLA-left precuneus connectivity was found to mediate the impact of interoception on cognitive empathy. In conclusion, this study provides valuable insights into the relationships among IS, alexithymia, and empathy. The right BLA-left precuneus connectivity may serve as a shared neural substrate between interoception and cognitive empathy.

Trauma, early life stress, and mindfulness in adulthood

This article is a review that was inspired by recent studies investigating the effects of childhood trauma or early life stress (ELS) and mindfulness in adulthood. One recent study found that some forms of abuse and neglect led to higher scores in several subscales of a self-report measure of mindfulness. The authors concluded that some forms of ELS can help cultivate certain aspects of mindfulness in adulthood. However, and in contrast to this recent finding, much of the extant literature investigating ELS and trauma are linked to emotional dysregulation, alexithymia, and a host of psychopathologies in adulthood which makes the results of this study surprising. Central to the mindfulness literature is cultivating an open, non-reactive, or non-judgment awareness of inner experiences which are important for emotional regulation. In this paper, I review some of the effects of trauma or ELS on critical neural circuits linked to mindfulness, interoception, attachment, and alexithymia which I hope may clarify some of the conflicting findings from this study and throughout the literature and provide additional context and a framework that may inform research investigating these two constructs going forward.

Heightened interoception in adults with fibromyalgia

Previous research suggests that the processing of internal body sensations (interoception) affects how we experience pain. Some evidence suggests that people with fibromyalgia syndrome (FMS) - a condition characterised by chronic pain and fatigue - may have altered interoceptive processing. However, extant findings are inconclusive, and some tasks previously used to measure interoception are of questionable validity. Here, we used an alternative measure - the Phase Adjustment Task (PAT) - to examine cardiac interoceptive accuracy in adults with FMS. We examined: (i) the tolerability of the PAT in an FMS sample (N = 154); (ii) if there are differences in facets of interoception (PAT performance, PAT-related confidence, and scores on the Private Body Consciousness Scale) between an FMS sample and an age- and gender-matched pain-free sample (N = 94); and (iii) if subgroups of participants with FMS are identifiable according to interoceptive accuracy levels. We found the PAT was tolerable in the FMS sample, with additional task breaks and a recommended hand posture. The FMS sample were more likely to be classified as 'interoceptive' on the PAT, and had significantly higher self-reported interoception compared to the pain-free sample. Within the FMS sample, we identified a subgroup who demonstrated very strong evidence of being interoceptive, and concurrently had lower fibromyalgia symptom impact (although the effect size was small). Conversely, self-reported interoception was positively correlated with FMS symptom severity and impact. Overall, interoception may be an important factor to consider in understanding and managing FMS symptoms. We recommend future longitudinal work to better understand associations between fluctuating FMS symptoms and interoception.

The Effect of Aviva Exercise Intervention on Pain Level and Body Awareness in Women with Primary Dysmenorrhea

Background and Objective: Primary dysmenorrhea (PD) is one of the most common clinical disorders in women of reproductive age. Our aim was to examine whether a twice-weekly thirty-minute Aviva exercise intervention could result in improvements in pain level and body awareness in patients with PD. Materials and Methods: In our prospective observational trial, the observation period included two consecutive menstrual cycles and the period of the next menstrual bleeding. The first menstrual bleeding period was the first measurement time (T1), the second was the second measurement time (T2), and the third was the third measurement time (T3) in a total of 78 volunteers. The primary endpoint was the change in the level of menstrual pain according to the Numeric Rating Scale (NRS) questionnaire between the intervention group (IG) and the control group (CG) at T1, T2, and T3. In this study, the secondary outcomes were the differences between the IG and CG regarding the different subscales of the Hungarian version of the Body Awareness Questionnaire (BAQ-H) at T1, T2, and T3; the Borg scale results of the IG; and adherence to the intervention. Statistical tests such as independent-sample t-tests, chi-square tests, Pearson's linear correlation coefficient, and repeated-measure ANCOVA were used for the analyses. Results: In total, 78 volunteers were enrolled: 40 persons in the IG and 38 in the CG. There was a significant change in the level of menstruation pain according to the NRS questionnaire between the IG and CG (p < 0.001). There was no significant difference between the IG and CG regarding the different subscales of the BAQ-H. Only in the case of the "Note responses or changes in body process" subscale of the BAQ-H was there a trend-like effect from the Aviva exercises (p = 0.086). Conclusions: The Aviva exercise could contribute to pain relief from PD. Regarding body awareness, no significant difference was found between the two groups. Due to the short detection period and prospective observational design, our results are preliminary and need to be confirmed in larger clinical trials.

Perception of benefits-barriers of exercise, physical activity level, and body awareness in women with premenstrual syndrome

INTRODUCTION

The study aims to investigate the relationship between premenstrual syndrome (PMS) and physical activity, body awareness, and the benefits/barriers to exercise (a), as well as to compare women with and without PMS in relation to these parameters (b).

MATERIALS AND METHODS

Participants were administered The Premenstrual Syndrome Scale (PMSS), International Physical Activity Questionnaire-Short Form (IPAQ-SF), Body Awareness Questionnaire, and The Exercise Benefits/Barriers Scale.

RESULTS

The age range of the participants included in the study was 19-48, with a mean age of 26.45 ± 7.14. A statistically significant difference was found between the women with and without PMS in terms of PMSS score, exercise benefits subscale score, and exercise barriers subscale score (p < 0.05). The results indicated that there was a significant positive correlation between PMSS score and exercise barriers subscale score (p < 0.05). There was a significant positive correlation between IPAQ score and body awareness questionnaire, exercise benefits subscale score, total score of exercise benefits and barriers of scale (p < 0.05). There was a significant negative correlation between IPAQ score and exercise barriers subscale score (p < 0.05). There was a significant positive correlation between body awareness questionnaire score and exercise benefits subscale score, total score of exercise benefits and barriers of scale (p < 0.05). There was a significant negative correlation between body awareness questionnaire score and exercise barriers subscale score (p < 0.05).

CONCLUSION

This study provide valuable insights into the relationship between PMS, physical activity, body awareness, and exercise benefits/barriers among women. By addressing the barriers and benefits to exercise and enhancing body awareness, healthcare professionals can potentially improve women's with PMS overall well-being and encourage them to adopt and maintain a physically active lifestyle.

Validation of the shortened 24-item multidimensional assessment of interoceptive awareness, version 2 (Brief MAIA-2)

The Multidimensional Assessment of Interoceptive Awareness (MAIA) was translated into many languages and frequently used in the last decade to assess self-reported interoceptive awareness. However, many studies demonstrated weaknesses regarding unstable factor structure and poor reliability of some scales. The 24-item Brief MAIA-2 questionnaire was developed, with only three items demonstrating the highest factor loadings in each of the eight scales of the MAIA-2. The cross-sectional online study used the 37-item MAIA-2 questionnaire in a non-clinical sample of 323 people aged between 16 and 75 (M = 26.17, SD = 9.12), including 177 women (54.80%). The sample comprised 156 athletes (48.30%) and 167 non-athletes (51.70%). The Confirmatory Factor Analysis showed adequate fit indices for a multidimensional model of the Brief MAIA-2, with the original eight scales: Noticing (awareness of subtle bodily sensations, such as the heartbeat, digestive sensations, or the breath), Not Distracting (ability to maintain attention to bodily sensations without being easily distracted by external stimuli), Not Worrying (tendency to not be overly concerned or anxious about bodily sensations or changes in the body), Attention Regulation (ability to regulate attention to bodily sensations and to shift attention between internal and external stimuli), Emotional Awareness (awareness and understanding of how emotions are associated with bodily sensations), Self Regulation (ability to regulate emotional responses and manage distress through an awareness of bodily sensations), Body Listening (tendency to listen to the body for insight and understanding), and Trusting (trust in bodily sensations as a source of information about one's feelings and needs). The hierarchical bi-factor (S·I - 1) model showed even better-fit indices. Therefore, the general factor of interoception was considered in further statistical tests. Confirmatory composite analysis showed high reliability and discriminant and convergent validity for most Brief MAIA-2 scales, except Noticing. Measurement invariance was confirmed across genders (Women, Men) and sports participation (Athletes, Non-athletes). However, group differences were also found for mean scores in particular scales of the Brief MAIA-2. Men scored significantly lower than women in Not Distracting but higher in Not Worrying, Attention Regulation, Self Regulation, Trusting, and the total score of interoceptive awareness. Gender discrepancies may be influenced by linguistic socialization, which tends to categorize shifts in internal states as either physiological or emotional. Athletes scored significantly lower than Non-athletes on the Not Distracting scale, but they showed higher scores in Noticing, Attention Regulation, Emotion Awareness, Self-Regulation, Body Listening, Trusting, and the global score, suggesting that physical training can improve most areas of interoception. Therefore, physical exercises and mindfulness training may be recommended to improve interoception, especially in women and people suffering from somatic and mental problems. The Brief MAIA-2 is a reliable and valid tool to measure multidimensional interoceptive sensibility in a non-clinical population. To improve well-being and athletic performance, Brief MAIA-2 can be used to assess the body's current perception of interoception and to detect its weak areas requiring improvement. However, the study has some limitations, such as a cross-sectional online self-report survey in a conventional non-clinical sample from Poland. Future cross-cultural studies should include representative samples for non-clinical and clinical populations from different countries and geographic regions to compare the Brief MAIA-2 with more objective psychophysiological methods of measuring interoception to reduce the limitations of these studies.

Effectiveness of mindfulness-based interventions on mental, cognitive outcomes and neuroplastic changes in older adults with mild cognitive impairment: A systematic review and meta-analysis

AIMS

To evaluate the effectiveness of mindfulness-based interventions (MBIs) on mental and cognitive outcomes including, anxiety, depression, attention, memory, global cognition and neuroplastic changes in older adults with mild cognitive impairment (MCI).

DESIGN

Systematic review and meta-analysis.

DATA SOURCE

A three-step search strategy was conducted on eight electronic databases, grey literature and reference lists from inception to February 2022.

REVIEW METHODS

Randomized controlled trials (RCTs) examining MBIs on older adults with MCI were screened and assessed for risk of bias using the Cochrane Risk of Bias Tool. Meta-analysis was conducted using RevMan using a random-effect model. Narrative synthesis was performed for studies where results could not be pooled statistically.

RESULTS

Ten RCTs were included in the review. Results suggested that right frontal parietal and left inferior temporal gyrus of the brain showed increased cortical thickness after receiving MBIs. There were significant interaction effects for global efficiency and significant interactions in the insular and gyrus regions. Functional connectivity between the posterior cingulate cortex, bilateral medial prefrontal cortex and left hippocampus were increased in participants undergoing MBIs. Nevertheless, meta-analysis showed non-significant pooled effects, favouring control groups on anxiety, depression, attention, memory and global cognition.

CONCLUSION

This review suggested the potential effects of MBIs in improving cortical thickness and connectivity in regions associated with memory and attention. Nevertheless, the effects of MBIs compared to active control groups on depression, anxiety, attention, memory and global cognition are inconclusive due to the lack of studies and non-significant results.

IMPACT

The review advocates for more rigorous studies with larger sample size and utilizing wait-list controls to evaluate the effects of MBIs. MBIs can be considered as an adjunct with other therapies to further enhance the effect on psychological and cognitive outcomes for older adults with MCI. No Patient or Public Contribution as this is a meta-analysis.

The relationship of pain, disability, physical activity, and body awareness with kinesiophobia in pregnant women with low back pain

PURPOSE/AIM

To investigate the relationship of pain intensity, disability level, physical activity level, and body awareness with kinesiophobia in pregnant women with low back pain (LBP).

MATERIALS AND METHODS

This cross-sectional study was conducted in the obstetrics and gynaecologic clinic of a tertiary centre. Eighty-six pregnant women were included in the study. Pain intensity, disability level, physical activity, body awareness, and kinesiophobia were assessed with a Visual Analogue Scale, the Oswestry Disability Index (ODI), the International Physical Activity Questionnaire-Short Form (IPAQ-SF), the Body Awareness Questionnaire (BAQ), and the Tampa Scale for Kinesiophobia (TSK), respectively.

RESULTS

Kinesiophobia score was high in pregnant women with LBP (40.01 ± 9.02). In pregnant women with LBP, a weak positive correlation was found between kinesiophobia with mean intensity of LBP (r = 0.339, p = 0.001) and intensity of LBP in activity (r = 0.283, p = 0.008); a moderate positive correlation between kinesiophobia and disability score (r = 0.539, p = 0.001); and a weak negative correlation between kinesiophobia and physical activity level (r = -0.308, p = 0.004) and body awareness (r = -0.324, p = 0.002). There was no relationship between kinesiophobia and intensity of LBP at rest (r = 0.160, p = 0.142) and nocturnal LBP intensity (r = 0.176, p = 0.105).

CONCLUSIONS

LBP intensity, disability level, physical activity level, and body awareness were significantly correlated with kinesiophobia in pregnant women with LBP. Therefore, kinesiophobia may be addressed as an important issue in pregnancy education programs.

Mind-body practices, interoception and pain: a scoping review of behavioral and neural correlates

OBJECTIVE

Chronic pain is a significant source of suffering in the United States, and many individuals increasingly turn towards yoga for pain relief. However, little is known regarding how yoga improves pain. Herein we seek to examine the scope of the literature linking mind-body practices, pain and interoception; an emerging mechanism by which yoga may improve chronic pain.

METHODS

This scoping review followed the five-stage methodological framework proposed by Arksey and O'Malley to examine behavioral and neural correlates of interoception in mind-body practices and pain. A broad search of the Pubmed, CINAHL, SportDiscus, Scopus, PsychInfo, and SocIndex databases was conducted, utilizing three clusters of search terms: (1) interoceptive terms, (2) mind-body terms, and (3) pain terms.

RESULTS

A combined total of 690 articles were screened, and 24 findings included for analysis. Sixteen studies examined interoceptive outcomes in response to mind-body practices for chronic pain, and 8 studies examined interoceptive outcomes in response to evoked-pain tasks in experienced mind-body practitioners. Only three studies linked yoga, interoception and pain.

CONCLUSION

This review relied on the broader mind-body literature to inform our analyses as the literature examining yoga, pain and interoception remains limited. Interoceptive techniques including attending to and acceptance of bodily sensations, appear to be key therapeutic mechanisms in mind-body practices for chronic pain. Future yoga-based interventions would benefit examining interoceptive outcomes and integrating interoceptive strategies to facilitate the pain-modulating benefits of yoga.

Mechanisms of improved body composition among perimenopausal women practicing Meditative Movement: a proposed biobehavioral model

OBJECTIVES

Weight gain and unfavorable body composition are prevalent among midlife/older women throughout menopause. These shifts may negatively impact health, well-being, and longevity. Efforts to attenuate weight and body composition changes are traditionally driven by manipulation of diet and/or exercise; however, sustained results are limited, possibly because the full spectrum of biobehavioral systems is not addressed by diet and exercise alone. We propose a biobehavioral model detailing mechanisms of body composition decline among perimenopausal women and the associated components of Meditative Movement (ie, tai chi, qigong, yoga) that address each of these factors.

METHODS

Based on our previous work and extensive review of the literature, we developed a multifactorial and multidimensional biobehavioral model including factors that most directly relate to body composition among perimenopausal women: 1) psychological (ie, stress and mood, mindfulness and self-compassion, body awareness), 2) behavioral (ie, sleep, physical activity, eating behaviors), and 3) physiological (ie, cortisol, estrogen). Relationships between each factor, Meditative Movement practice components, and predicted effects on body composition were explored in detail.

RESULTS

Our model describes select psychological, behavioral, and physiological factors, and potential mechanistic pathways of Meditative Movement practice driving improved changes in body composition and weight outcomes for perimenopausal women.

CONCLUSIONS

The proposed model details a novel, evidence-supported means to reduce the risk of deleterious shifts in body composition throughout perimenopause and menopause thereafter. We suggest that these changes may occur directly and/or indirectly through psychological, behavioral, and physiological mechanisms that facilitate the desired changes in body composition.

Linguistic embodiment in typical and atypical anorexia nervosa: Evidence from an image-word matching task

OBJECTIVE

The integration of sensory, motor, and cognitive systems is embodied cognition, according to which mind and body are not separate and distinct, and our body (and our brain, as part of the body) contributes to determining our mental and cognitive processes. In spite of limited data available, Anorexia nervosa (AN) appears as a condition in which embodied cognition is altered, in particular, if we consider bodily sensations and visuospatial information processing. We aimed to evaluate the ability to correctly identify body parts and actions in both full (AN) and atypical AN (AAN), looking at the role of the underweight status.

METHOD

A group of 143 females (AN = 45, AAN = 43, unaffected women = 55) was enrolled. All participants performed a linguistic embodied task to evaluate the association between a picture-showing a bodily action-and a written verb. Additionally, a subsample of 24 AN participants performed a retest after stable weight recovery.

RESULTS

Both AN and AAN demonstrated an abnormal ability to evaluate the picture-written verb associations, especially if the involved bodily effectors were the same in both stimuli (i.e., pictorial and verbal) and needed a longer response time.

CONCLUSIONS

Specific embodied cognition linked to body schema seems to be impaired in persons with AN. The longitudinal analysis showed a difference between AN and AAN only in the underweight condition, suggesting the presence of an abnormal linguistic embodiment. More attention should be devoted to embodiment during AN treatment to improve bodily cognition, which might, in turn, diminish body misperception.

Exploration of interoceptive capabilities in avoidant/restrictive food intake disorder and anorexia nervosa

OBJECTIVE

This proof-of-concept study explores the role of aberrant interoception as a possible mechanism underlying restrictive eating symptoms in avoidant/restrictive food intake disorder (ARFID) compared to anorexia nervosa (AN) and healthy comparisons (HC).

METHOD

We report preliminary normative adolescent interoceptive data in HCs (n = 100) compared to adolescents with ARFID (n = 30) and AN (N = 23). Adolescents (12-18) participated in a one-time virtual visit to assess heartrate guessing accuracy (interoceptive accuracy), correlation between confidence in heartrate guess and accuracy (interoceptive awareness), and self-reported interoception (interoceptive sensibility).

RESULTS

HC adolescents had comparable interoceptive outcomes relative to published adult norms, consistent with existing literature. Data suggest that adolescents with ARFID have poor heartbeat guessing accuracy and experience challenges deciphering interoceptive signals, possibly contributing to symptoms. While adolescents with AN have greater heartbeat guessing accuracy, they cite difficulty trusting body cues, perhaps contributing to their lack of confidence in interoceptive cue detection.

CONCLUSIONS

Preliminary results reflect differences in interoception between the three groups.

Position: A study protocol for the prevention of fall injuries in french special forces selection courses using a body-centered intervention

INTRODUCTION

The Military Physical and Sports Training program was developed by the French Army in order to train, optimize, and maintain individual readiness. Although the health benefits of sport practice do not need to be demonstrated, such activities can cause acute musculoskeletal injuries that need to be addressed. The prevalence of lower limb injury is rather high in the French military population and, in particular, ranges from 15 to 45% during Special Forces selection courses. Thus, this project aims to investigate the efficiency of a body-centered program designed to enhance body awareness. The program seeks to train the mind to actively pay attention to body information, while the latter is viewed as a protective factor against fall injuries. We assume: (i) that postural control can be improved by enhancing the level of body awareness; and (ii) that greater postural awareness could be beneficial in reducing the risk of fall injuries. The body-centered prevention program is based on the Optimization of the Resources of the Armed Forces (ORAF) intervention, which focuses on mental preparation and recovery, and has been deployed in the French Army for many years.

METHOD AND ANALYSES

The study focuses on five French Special Forces selection courses (400 soldiers/ participants). It is divided into two stages (year 1, year 2). The first year is dedicated to data collection from the control group (200 participants), while in the second year the ORAF intervention will be deployed. In both year, participants will be subjected to the same enrollment schedule (Fig 3). The main objective is to evaluate the effectiveness of the ORAF intervention in reducing the rate of fall injuries during military selection, based on a multidisciplinary method that captures demographic, biological, biometric, clinical, and para-clinical measures.

Body-and movement-oriented interventions for posttraumatic stress disorder: An updated systematic review and meta-analysis

This study is an update of the meta-analysis we published in 2019 on the effectiveness of body- and movement-oriented interventions (BMOIs) for adults with posttraumatic stress disorder (PTSD) in decreasing PTSD symptoms and secondary outcomes of depressive symptoms, sleep disturbance, and interoceptive awareness. Search terms for BMOIs and PTSD were combined to identify eligible studies in four bibliographical databases. Articles were selected if they included adult participants with a primary diagnosis of PTSD, included BMOI as one of the investigated therapies, were designed as a comparative outcome trial with any control condition, and involved a standardized outcome measure for PTSD symptom severity. This resulted in the addition of 14 new studies compared to the 2019 study. The meta-analysis, which included 29 studies in total, resulted in a mean Hedges' g effect size of 0.50, 95% CI [0.22, 0.79], in decreasing PTSD symptoms, with very high heterogeneity, I2 = 89%. Meta-analyses of secondary outcomes resulted in Hedges' g effect sizes of 0.37, 95% CI [0.08, 0.66] for depressive symptoms; 0.62, 95% CI [0.42, 0.81] for sleep quality; and -0.10, 95% CI [-0.23, 0.43] for interoceptive awareness. The risk of bias analysis resulted in some concerns or high risk of bias in almost all included studies; only one study had a low risk of bias. We conclude that BMOIs may be valuable for patients with PTSD. There is, however, still a lack of high-quality studies with proper control conditions and long-term follow-up periods from which to draw conclusions.

Relationship between body awareness level and musculoskeletal pain complaints, physical activity level and emotional status in healthy people

INTRODUCTıON/AIM: Defining the physical, psycho-social effects of body awareness may help to explain the functional effects. It was aimed to examine the relationship between the body awareness level and musculoskeletal pain complaints, physical activity level, and emotional state in healthy people.

MATERIALS AND METHODS

A total of 289 healthy individuals between the ages of 18 and 25 were included in the study. Body awareness level was using Body Awareness Questionnaire (BAQ), musculoskeletal pain complaint using The Nordic Musculoskeletal Questionnaire (NMQ), physical activity levels using International Physical Activity Questionnaire (IPAQ-short form) and emotional status using Beck Depression Inventory (BDI) were assessed.

RESULTS

The mean age of the participants was 19.50 ± 1.55 years. The mean pain intensity was 2.48 ± 1.99. The BAQ score average was 91.87 ± 15.55. Thirty percent of the participants had a mild level and 14.9% had a moderate level of depression risk. While there was a weak positive relationship between the Disease Startup sub-dimension of BAQ and the moderate-level IPAQ score (r = 0.135, p = 0.022). Also there was a weak negative relationship between Disease Startup sub-dimension and the level of depression risk. A weak positive relationship was found between the changes in the body process and attention to subjects sub-dimension and the level of depression risk (r = 0.127, p = 0.030). There was a positive correlation between level of depression risk and pain intensity (r = 0.237, p = 0.000). Body awareness levels of individuals who had back pain in the last 1 month were higher than those who did not experience pain (p = 0.029).

CONCLUSION

The results of the study showed that physical activity positively affected body awareness level. The body awareness level was directly related to the pain associated with the musculoskeletal system and emotional state. There is a need more studies examining the relationship between body awareness and pain, physical activity and emotional status with subdimensions of the BAQ.

Psychological interventions for interoception in mental health disorders: A systematic review of randomized-controlled trials

Disturbed interoception (i.e., the sensing, awareness, and regulation of internal body signals) has been found across several mental disorders, leading to the development of interoception-based interventions (IBIs). Searching PubMed and PsycINFO, we conducted the first systematic review of randomized-controlled trials (RCTs) investigating the efficacy of behavioral IBIs at improving interoception and target symptoms of mental disorders in comparison to a non-interoception-based control condition [CRD42021297993]. Thirty-one RCTs fulfilled inclusion criteria. Across all studies, a pattern emerged with 20 (64.5%) RCTs demonstrating IBIs to be more efficacious at improving interoception compared to control conditions. The most promising results were found for post-traumatic stress disorder, irritable bowel syndrome, fibromyalgia and substance use disorders. Regarding symptom improvement, the evidence was inconclusive. The IBIs were heterogenous in their approach to improving interoception. The quality of RCTs was moderate to good. In conclusion, IBIs are potentially efficacious at improving interoception for some mental disorders. In terms of symptom reduction, the evidence is less promising. Future research on the efficacy of IBIs is needed.

Sustained practice of Qigong results in a somatic hermeneutic process, contributing to appreciation of life. An interpretative phenomenological analysis

Over the past few decades evidence has accumulated into the health benefits of practising Qigong, particularly in the amelioration of physical conditions. Previous studies have been conducted using positivist biomedical model methodologies, which may be limited in understanding the nuanced meaning-making and embodied experience of practitioners. This study uses Interpretative Phenomenological Analysis (IPA) to inquire into how the sustained practice of Qigong contributes beyond the relief of physical conditions to improved self-awareness and appreciation of life. Semi-structured interviews were conducted with five Qigong practitioners who each had over 10-years' experience and analysed using the interpretive methodology of IPA. Findings reveal a crucial antecedent theme of 'Openness to experience' and four, interrelated, super-ordinate themes common to each of the participants: 'Finding a Teacher', 'Bodymind' (proprioception and interoception), 'Primary Process of Developmental Change', and 'Awareness of emergent Authenticity'. Insights revealed how each practitioner makes sense of the sustained 'autotelic' practice of Qigong, and how this contributes to a transformative understanding of themselves and of life. Qigong presents a possible promising intervention to improve both physical and psychological well-being.

Dysfunctional self-reported interoception predicts residual symptom burden of fatigue in major depressive disorder: an observational study

BACKGROUND

Fatigue is a core symptom of major depressive disorder (MDD) and is frequently refractory to antidepressant treatment, leading to unfavorable clinical/psychosocial outcomes. Dysfunctional self-reported interoception (i.e., maladaptive focus on the body's physiological condition) is prevalent in MDD and could contribute to residual symptom burden of fatigue. Therefore, we explored (a.) cross-sectional correlations between both dimensions and investigated (b.) prospective associations between interoceptive impairments at admission and symptom severity of fatigue at the end of hospitalization.

METHODS

This observational, exploratory study included 87 patients suffering from MDD who completed self-rating scales, the Multidimensional Assessment of Interoceptive Awareness, Version 2 (MAIA-2), and the Multidimensional Fatigue Inventory (MFI-20), at the beginning and end of hospitalization. Bivariate correlations (r) and hierarchical regression analyses were performed.

RESULTS

The cross-sectional analysis showed moderate to large negative correlations between the MAIA-2 and MFI-20 dimensions except for the Not-Distracting scale. Symptoms of general, physical, and mental fatigue at the end of hospitalization were predicted by reduced body Trusting (β = -.31, p = .01; β = -.28, p = .02; β = -.31, p = .00, respectively). Increased Body Listening (β = .37, p = .00), Not-Worrying (β = .26, p = .02), and diminished Attention Regulation (β = -.32, p = .01) predicted higher mental fatigue.

CONCLUSIONS

Diminished body confidence at baseline identified patients at risk for post-treatment fatigue and could therefore serve as a target for improving antidepressant therapy. Body-centered, integrative approaches could address treatment-resistant fatigue in MDD. However, clinicians may also consider the potential adverse effect of increased Body Listening and Not-Worrying on mental fatigue in psychotherapeutic and counselling approaches. Due to the exploratory nature of this study, the results are preliminary and need to be replicated in pre-registered trials with larger sample sizes.

Cross-Cultural Adaptation, Reliability, and Validity of the Greek Version of the Fremantle Shoulder Awareness Questionnaire (FreSHAQ-GR) in Patients with Chronic Shoulder Pain

Shoulder pain is one of the most common musculoskeletal pathologies. The association of shoulder pain with impaired proprioception and bodily self-awareness called for the cross-cultural adaptation of the Fremantle Shoulder Awareness Questionnaire (FreSHAQ) in Greek. The FreSHAQ is a relatively new self-assessment 9-item scale for impaired somatic awareness in patients with shoulder pain. The study included 100 participants (54 women) between 20 and 80 years old, with chronic shoulder pain (>3 months duration), able to comprehend and speak Greek, and recruited from three private physical therapy practices. The cross-cultural adaptation process was followed to develop the Greek version of the questionnaire (FreSHAQ-GR). Further testing for construct validity via exploratory factor analysis and correlational analysis with the Shoulder Pain and Disability Index (SPADI), the Quick Disabilities of Arm, Shoulder, and Hand (QuickDASH), the pain catastrophizing scale (PCS), a pain intensity visual analog scale (PI-VAS) in the last week, and the demographic characteristics followed. Test-retest reliability of the FreSHAQ-GR in a sub-sample of patients (n = 25) was tested upon repeated completion of the scale after a week and examined with the intraclass correlation coefficient (ICC2,1), the standard error of the measurement (SEM), and the minimum detectable change (MDC) indices. The internal consistency of the scale was also assessed. The factor analysis revealed that the scale comprised one factor relevant to shoulder awareness but with fewer items (first 6 items) than the original FreSHAQ. Additionally, the FreSHAQ-GR (both versions) demonstrated statistically significant correlations (Spearman's r) with participants' age (r = -0.31/-0.29, p < 0.002), the PI-VAS (r = 0.54/0.52, p < 0.001), the SPADI total score and both of its subscales (r = 0.39-0.45/0.34-0.39, p < 0.001), the QuickDASH (r = 0.37/0.34, p < 0.001), and the PCS (r = 0.50/0.40, p < 0.001). The questionnaire's internal consistency (Cronbach's α/McDonald's ω) was 0.833/0.827 for the 9-item and 0.871/0.867 for the 6-item FreSHAQ-GR. Test-retest reliability was excellent for both versions of the FreSHAQ-GR (ICC2,1(95% CI) = 0.97/0.98 (0.91-0.99/0.94-0.99), and with a low error margin (SEM = 1.31/0.94 and MDC95% = 3.63/2.61). Therefore, the FreSHAQ-GR (6-item version) possesses very good measurement properties and can be administered to Greek-speaking patients with chronic shoulder pain.

Well-being predictors of body composition and associated behavioral risk factors in midlife/older women participating in a meditative movement intervention: an exploratory analysis

Introduction

Greater than 40% of women are obese, a key risk factor for cardiometabolic, neurocognitive disease, mood disorders, and certain cancers. Obesity and unfavorable body composition can compromise physical and psychological health and well-being. Preliminary evidence demonstrates Meditative Movement (i.e., Tai Chi Easy) improves health outcomes and body composition among midlife/older women. This single-group pilot study explored relationships between well-being predictors related to body composition and associated behavioral risk factors in midlife/older women pre-to-post Tai Chi Easy intervention.

Methods

Eligible women 45-75 years old, participated in once-weekly 30-minute Tai Chi Easy classes over 8-weeks. Pre/post-intervention data included self-report surveys and on-site body composition. Multivariate linear regression models were fitted with putative predictor variables having correlations p-values of 0.20 or less with sleep quality and eating behaviors.

Results

Participants (N = 36) (M age = 53.7) were White (80.4%) and attended ≥ 4 years of college (70.6%). Analyses resulted in one independent variable per model as a predictor of the dependent variables of sleep quality and emotional eating. Results indicated: (1) stress explained 13.4% sleep quality variance (F (2, 20) = 2.71, p = 0.09) and (2) self-compassion explained 42.1% emotional eating variance (F (2, 31) = 12.54, p < .01).

Conclusion

Findings suggest stress and self-compassion partially explain variance in the dependent variables of sleep quality and emotional eating, both associated behavioral risk factors of body composition. Additional research may guide interventions to test efficacy and examine mediators to improve well-being predictors, body composition, and associated behavioral risk factors among midlife/older women.

Key constructs of body awareness impairments post-stroke: a scoping review of assessment tools and interventions

PURPOSE

To summarise body awareness assessment tools and interventions relevant for stroke rehabilitation using a framework that categorises key body awareness constructs, disorders and impairments.

MATERIALS AND METHODS

Online electronic databases and trial registries were searched from inception until July 2021, in addition to hand searching reference lists of included studies and reviews. Study selection included any study design where the investigation involved assessing and/or intervening in body awareness following stroke. Data were extracted based on predefined criteria by two independent reviewers and mapped to the emergent framework.

RESULTS

The final analysis included 144 papers that reported 43 assessment tools and 8 types of interventions for body awareness. Consensus was reached on a synthesised body awareness framework. This comprised specific impairments and disorders, constructs, sub-categories and main categories leading to the overarching term of body awareness. Clinical and psychometric properties of the assessment tools were not reported or poorly evaluated, and the interventions lacked robust study designs and rigorous methods.

CONCLUSIONS

The framework produced will enable future research and clinical practice to be based on consistent concepts and definitions. Clinicians can also use this information to cautiously select assessment tools and/or interventions but are reminded of the limitations identified in this review.Implications for rehabilitationThere is limited understanding, compounded by inconsistent terminology and definitions regarding body awareness after stroke.A synthesized framework to define key constructs and definitions of body awareness is proposed.Assessment tools and interventions reported in the literature are mapped to the proposed framework.Psychometric properties of available tools are reported.Significant work remains to refine concepts of body awareness, develop and evaluate assessment tools and interventions.

Fear of falling in women: A psychological training intervention improves climbing performance

The main purpose of this study was to determine the effect of a psychological training intervention based on emotional regulation on anxiety and climbing ability in women climbers with fear of falling. A secondary aim was to compare the outcomes of climbing ability, anxiety, self-confidence and interoceptive awareness (IA) between the psychological group (PG), a training (TG) and a control group. Self-reported climbing ability, anxiety and IA were assessed using Competitive State Anxiety Inventory-2 and the Multidimensional Assessment of Interoceptive Awareness questionnaire. Results indicated a significant improvement in climbing ability for both PG and TG. The PG showed a significant reduction in cognitive and somatic anxiety, while the TG only exhibited a reduction in cognitive anxiety. Moreover, the PG demonstrated a greater significant increase in self-confidence compared to the TG. IA improved in five subscales for the PG, whereas the TG changed in only two subscales. In conclusion, a psychological training intervention focusing on emotional regulation might contribute to improvements in IA, reduced anxiety levels, and enhancements in climbing ability and self-confidence among women climbers facing fear of falling.

Psychometric properties of an Arabic translation of the multidimensional assessment of interoceptive awareness (MAIA-2) questionnaire in a non-clinical sample of Arabic-speaking adults

BACKGROUND

Interoception refers to processes through which the nervous system identifies, analyzes, and integrates the information generated by the physiological state of the body (e.g., from internal organs such as the stomach, heart, or lungs). Despite its potential interest for clinical research and its wide use globally, no Arabic adaptation and validation of the Multidimensional Assessment of Interoceptive Awareness (MAIA-2) questionnaire exists to date. The goal of this study was to examine the psychometric properties of an Arabic translation of the MAIA-2 in a sample of Arabic-speaking community adults from Lebanon. We hypothesized that the Arabic version of the MAIA-2 would yield adequate internal consistency coefficients; the 8-factor structure model would show a good fit to our data, with measurement invariance and good convergent validity.

METHOD

The Arabic adaptation of the MAIA-2 was developed using the forward-backward translation method. A non-clinical sample of Arabic-speaking adults (n = 359, 59.9% females, mean age = 22.75 years (SD = 7.04)) took part of this validation study. To check if the model was adequate, several fit indices were calculated: the normed model chi-square (χ²/df), the Steiger-Lind root mean square error of approximation (RMSEA), the Tucker-Lewis Index (TLI) and the comparative fit index (CFI). Values ≤ 3 for χ²/df, and ≤ 0.08 for RMSEA, and 0.90 for CFI and TLI indicate good fit of the model to the data.

RESULTS

Confirmatory Factor Analyses corroborated the validity of the original 8-factor structure of the MAIA-2 [χ2/df = 1603.86/601 = 2.67, RMSEA = 0.068 (90% CI 0.064, 0.072), SRMR = 0.058, CFI = 0.903, TLI = 0.892]. Reliability estimates in our sample revealed good internal consistency, with McDonald's ω coefficients for the subscales ranging from 0.86 to 0.93. Our analyses also revealed measurement invariance of the Arabic MAIA-2 for gender. No statistically significant difference between men and women in all dimensions, except for the not worrying and attention regulation subscales where men scored significantly higher than women. Finally, the Arabic MAIA-2 dimensions showed positive correlations with the intuitive eating dimension "Reliance on Hunger and Satiety Cues", thus providing support for convergent validity.

CONCLUSION

We contribute the literature by providing the first Arabic adaptation and validation of a measure assessing the multidimensional construct of self-reported interoception. The Arabic MAIA-2 demonstrated good psychometric properties. We thus preliminarily recommend its use to measure the interoceptive awareness construct among Arabic-speaking communities worldwide.

Mediators of improved PTSD symptoms in veterans and civilians following a yoga program

OBJECTIVE

Although yoga shows some promise as an intervention for post-traumatic stress disorder (PTSD), little is known about how yoga reduces PTSD symptoms. The current study hypothesised that aspects of interoceptive awareness would mediate the effect of a yoga intervention on PTSD symptoms.

METHODS

We used data from our recently completed randomised controlled trial of a 16-week holistic yoga programme for veterans and civilians diagnosed with PTSD (n = 141) that offered weekly 90-minute sessions. We conducted a mediation analysis using interoceptive awareness and other variables that were associated with PTSD symptom reduction at mid-treatment and treatment end.

RESULTS

Although measures of anxiety, interoceptive awareness, and spirituality were identified in individual mediator models, they were no longer found to be significant mediators when examined jointly in multiple mediator models. When examining the multiple mediator models, the strongest mediator of the yoga intervention on PTSD symptoms was mental well-being at mid-treatment and stigma at the treatment end. The total effect of yoga on CAPS and PCL at the treatment end mediated by stigma was 37.1% (-1.81/-4.88) and 33.6% (-1.91/-5.68), respectively.

CONCLUSION

Investigation of mental well-being and mental illness stigma as potential mediators is warranted in future studies of yoga as a treatment for PTSD as they may prove to be important foci for yoga interventions.

Sensory and affective aspects of the perception of respiratory resistance

Perception of airway resistance has a sensory and an affective aspect, i.e., perceived resistance and unpleasantness, respectively. The current study aimed to shed more light on the relationship of these aspects, as well as their malleability to trait-like aspects of body awareness. In a laboratory study, 71 young participants completed two respiratory resistive load discrimination tasks relying on sensory and affective evaluation, respectively, and filled out questionnaires assessing somatosensory amplification, anxiety sensitivity, somatic symptoms distress, and breath awareness. Frequentist and Bayesian statistical analysis revealed no differences in discrimination accuracy with respect to the sensory and affective aspect of perceived resistance. Psychological traits were not associated with accuracy scores. In conclusion, affective evaluation of respiratory load is as accurate as sensory evaluation. Neither sensory not affective accuracy is influenced by various aspects of body awareness.

Influence of psychological inflexibility and mindfulness on hypersexuality and sexual satisfaction in a Spanish sample

Sexual satisfaction is tremendously relevant to wellbeing and quality of life. Inversely, hypersexuality may increase the risk of psychological distress, unprotected sex, and marital problems. This study attempts to explore the sociodemographic variables related to hypersexuality and the relationship between hypersexuality and sexual dissatisfaction with psychological inflexibility, cognitive fusion, body awareness, bodily dissociation, and mindfulness skills in the Spanish population. The sample was made up of 530 participants between 18 and 67 years of age. In total, 5.5% displayed hypersexuality, more likely in males, lesbians and gay men, singles, and students. An online survey was conducted including standardized questionnaires as follows: AAQ-II, CFQ, SBC, MAAS, NSSS-S, and HBI. Significant moderate positive correlations were found between hypersexuality and psychological inflexibility, cognitive fusion, and bodily dissociation, and an inverse moderate correlation with mindfulness skills. Moderate negative correlations were found between sexual satisfaction and bodily dissociation. Linear regression showed psychological inflexibility was the variable with the most weight on hypersexuality, while bodily dissociation was the variable with the most influence on sexual dissatisfaction. This study suggests lesbians and gay men, males, and singles may show an increased vulnerability toward engaging in hypersexual behavior and provides justification for interventions focused on psychological inflexibility and mindfulness skills to treat hypersexuality and improve sexual satisfaction.

The role of the body in the experience of installation art: a case study of visitors' bodily, emotional, and transformative experiences in Tomás Saraceno's "in orbit"

Installation art, with its immersive and participatory character, has been argued to require the use and awareness of the body, which potentially constitute key parts of the artwork's experience and appreciation. Heightened body awareness is even argued to be a key to particularly profound emotional or even transformative states, which have been frequently ascribed to this genre. However, the body in the experience of installation art has rarely been empirically considered. To address this gap, we investigated the body's role in the experience of Tomás Saraceno's in orbit installation. Based on a list of self-report items created from a review of the theoretical literature, we-for the first time-captured (quantitatively and qualitatively): what kind of subjective bodily experiences visitors (N = 230) reported, how these items grouped into clusters (using network science), and how these relate to emotion, art appraisal, and transformative outcomes. Network analysis of the items determined four communities related to "interoception," "presence," "disturbance," and "proprioception." Proprioception (e.g., awareness of balance/movement/weight) turned out to be a significant determinant of art appreciation in our study, and, together with "disturbing" body experiences (feeling awkward/watched/chills), coincided with transformation. We also assessed individual differences in body awareness yet did not find that these moderate those relationships. We suggest future research on installation art based on a more unified assessment of the role of the body in embodied-enactive aesthetics and its relation to the intensity and impact of art experience in general.

Neurophysiological and Psychosocial Mechanisms of Fibromyalgia: A Comprehensive Review and Call for An Integrative Model

Research into the neurobiological and psychosocial mechanisms involved in fibromyalgia has progressed remarkably in recent years. Despite this, current accounts of fibromyalgia fail to capture the complex, dynamic, and mutual crosstalk between neurophysiological and psychosocial domains. We conducted a comprehensive review of the existing literature in order to: a) synthesize current knowledge on fibromyalgia; b) explore and highlight multi-level links and pathways between different systems; and c) build bridges connecting disparate perspectives. An extensive panel of international experts in neurophysiological and psychosocial aspects of fibromyalgia discussed the collected evidence and progressively refined and conceptualized its interpretation. This work constitutes an essential step towards the development of a model capable of integrating the main factors implicated in fibromyalgia into a single, unified construct which appears indispensable to foster the understanding, assessment, and intervention for fibromyalgia.

Feeling difficult to identify: Alexithymia is inversely associated with positive body image in adults from the United Kingdom

BACKGROUND

Research has increasingly examined the ways in which internal bodily experiences influence body image, including the relationship between alexithymia - the reduced ability to identify and describe one's own emotional feelings and bodily sensations - and negative body image. However, relationships between facets of alexithymia and positive body image remain unexplored.

METHODS

To bridge this gap in the literature, we assessed relationships between facets of alexithymia and multiple, core indices of positive body image in an online sample of adults from the United Kingdom. A total of 395 participants (226 women, 169 men) aged 18 to 84 years completed measures of alexithymia, body appreciation, functionality appreciation, body image flexibility, body acceptance by others, and positive rational acceptance.

RESULTS

Once the effects of age had been accounted for, alexithymia was significantly and negatively associated with all five body image constructs in hierarchical multiple regressions. In the final models, the alexithymia facet of Difficulties Identifying Feeling emerged as a significant and negative predictor of all indices of positive body image.

LIMITATIONS

The use of cross-sectional data limits the causal conclusions that can be drawn.

CONCLUSIONS

These findings extend previous work by demonstrating the unique relationship between alexithymia and positive body image, providing important implications for body image research and practice.

Embodied Mindfulness Questionnaire: Scale Development and Validation

Recently developed mindfulness scales have integrated aspects of the body in measuring mindfulness unlike other established scales. However, these scales focused solely on body awareness and did not embrace all aspects of mindfulness and the body. Specifically, they did not integrate embodiment in mindfulness. The proposed Embodied Mindfulness Questionnaire (EMQ) aims to operationalize the proposed notion of "embodied mindfulness" by grounding it into five dimensions, each representing a set of skills that can be cultivated through training and practice: (a) Detachment from Automatic Thinking, (b) Attention and Awareness of Feelings and Bodily Sensations, (c) Connection with the Body, (d) Awareness of the Mind-Body Connection, and (e) Acceptance of Feelings and Bodily Sensations. The EMQ items were developed through consultations with a panel of eight graduate students and a group of 10 experts in the field. Results from a series of three studies supported the proposed five subscales of EMQ and suggested that these subscales are independent and supported by convergent and discriminant evidence. In addition, results suggested that scores of EMQ subscales are different in terms of sensitivity to mindfulness training or meditation practice and experience. Limitations, as well as theoretical and practical implications of the EMQ subscales, are thoroughly discussed.

An evolutionary account of impairment of self in cognitive disorders

Recent research has proposed that certain aspects of psychosis, as experienced in, e.g., schizophrenia (SCZ), but also aspects of other cognitive conditions, such as autism spectrum disorders (ASD) and synesthesia, can be related to a shattered sense of the notion of self. In this paper, our goal is to show that altered processing of self can be attributed to an abnormal functioning of cortico-striatal brain networks supporting, among other, one key human distinctive cognitive ability, namely cross-modality, which plays multiple roles in human cognition and language. Specifically, our hypothesis is that this cognitive mechanism sheds light both on some basic aspects of the minimal self and on some aspects related to higher forms of self, such as the narrative self. We further link the atypical functioning in these conditions to some recent evolutionary changes in our species, specifically, an atypical presentation of human self-domestication (HSD) features. In doing so, we also lean on previous work concerning the link between cognitive disorders and language evolution under the effects of HSD. We further show that this approach can unify both linguistic and non-linguistic symptoms of these conditions through deficits in the notion of self. Our considerations provide further support for the hypothesis that SCZ and ASD are diametrically opposed cognitive conditions, as well for the hypothesis that their etiology is associated with recent human evolution, leading to a deeper understanding of the causes and symptoms of these disorders, and providing new cues, which can be used for an earlier and more accurate diagnostics.

Oral health and mental health in healthy adults, a topic of primary prevention and health care, empirical results from two online studies

Oral health is an important, yet often neglected aspect of health and well-being. Among geriatric populations, oral diseases, poor oral health, and reduced oral hygiene behavior are major comorbid factors of geriatric diseases such as dementia, cardiovascular diseases, or mental health conditions. However, little is known so far about the relationships between oral health and mental health in the younger adult population, who is yet not suffering from any disorder. In the present manuscript the results of two online studies, online study 1, n = 133, all-female sample and online study 2: n = 29, mixed gender sample, are reported that investigate the relationship between self-reported oral health impairments and preclinical symptoms of mental disorders including self-reported symptoms associated with depression or eating disorders as well as self-reported perceived stress and behavior change related to the COVID-19 pandemic. The results of both studies support links between self-reported oral health impairments, self-reported depressive symptoms (including anxiety and current affect) and symptoms related to eating disorders (such as bulimic behavior, body dissatisfaction or drive for thinness) among young adults and suggest that perceived stress may contribute to both, impaired oral health and impaired mental health in young adults (women and men).

Post-Traumatic Orientation to Bodily Signals: A Systematic Literature Review

Theoretical literature suggests that trauma and (PTSD) may instigate changes in the interpretation of bodily signals. Some findings support these inquiries, revealing that exposure to traumatic events and PTSD are associated with pain catastrophizing, body vigilance, fear of pain, and other manifestations of bodily perceptions and interpretations. However, these findings are not integrated into an inclusive empirically based conceptualization, thus leading to a limited comprehension of this phenomenon. This systematic literature review was conducted to synthesize the existing literature referring to orientation to bodily signals. Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, the review included a final of 48 manuscripts that addressed orientation to bodily signals among participants (aged 18 and above) and its potential associations with PTSD. The review revealed that most studies assessed one orientation manifestation, which was tested for its link to PTSD. The majority of the manuscripts were cross-sectional and included participants who faced combat, vehicle accidents, or various types of traumas. Only five manuscripts focused on interpersonal trauma and abuse. Most manuscripts reported significant correlations, revealing that trauma and PTSD are associated with a negative, catastrophic and frightful interpretation of bodily signals. These findings emphasize the need to encapsulate the various manifestations of orientation to bodily signals under a unified construct, as proposed by the term post-traumatic orientation to bodily signals. Further research is needed to illuminate the circumstances and processes by which trauma is implicated in post-traumatic orientation to bodily signals.

Interoceptive sensibility differentiates the predictive pattern of emotional reactivity on depression

The role of emotional reactivity in the psychopathology of depression has been studied widely but not comprehensively. Inconsistencies in existing literature indicate the presence of other factors may affect this dynamic. An individual's method of processing their physiological sensations is a third variable because emotions are psychophysiological. This study identified the predictiveness of ease of activation, intensity, and duration of negative and positive emotions on depressive symptoms differentiated by interoceptive sensibility (IS). A total of 270 community participants filled-in questionnaires assessing their IS, habitual emotional reactivity, depressive severity, and response bias. A two-step clustering analysis identified the IS characteristics. Negative and positive reactivity models among each IS cluster were tested using bootstrapping regression, controlling for gender and response bias. IS can be clustered into "high IS," "low IS," and "worriers." Both positive and negative reactivity's predictiveness patterns on depression were different between IS clusters. Lower positive reactivity predicted depression among individuals with low IS (harder to activate positive emotions) and worriers (shorter duration of positive emotions) but not among individuals with high IS. Those with high IS also exhibited the highest positive reactivity. Ease of activating negative emotions predicted depression among high IS individuals, and a longer duration of negative emotions predicted depression among worriers. IS may affect the psychopathology of depression through subjective emotional reactivity. Thus, IS characteristics can be incorporated into intervention plans.

‘A blessing and a burden’: Exploring post traumatic growth in doctors with acquired invisible disability—An interpretative phenomenological analysis

OBJECTIVES

Qualitative studies of the relationship between acquired invisible disability (AcqID) and posttraumatic growth (PTG) are scant, especially in the context of healthcare professionals. This study aimed to explore in-depth accounts of the lived experience of PTG in doctors with AcqID arising from physical illness with cognitive dysfunction.

DESIGN

Five doctors who had been diagnosed in the last decade with a physical illness with cognitive dysfunction resulting in an AcqID, and who self-reported at least one feature of PTG participated in this qualitative research study.

METHODS

Semi-structured interviews were used to collect data, which were analysed using interpretative phenomenological analysis.

RESULTS

This study recognized that AcqID supported a process of PTG for participants. Three superordinate themes were apparent across the sample: identity (The human left behind), self (Acceptance of the disabled self), and rebirth (The phoenix rises from the ashes). Human connection, service as a value, and the role of the body were found to be key facilitators of PTG in these participants. This study offers new perspectives on cognitive-embodied appreciation in facilitating PTG in doctors with AcqID.

CONCLUSIONS

While the participants perceived AcqID with cognitive dysfunction to be a trauma, they also experienced PTG, Corporeal PTG and a new considered domain, Cognitive-Embodied PTG. The unrealised potential of PTG can be harnessed if doctors with disability are viewed as assets to the medical profession, and diversity is promoted through the provision of appropriate support. Thus, there is potential to cultivate a flourishing, inclusive, and compassionate culture within medicine.

Stress, subjective wellbeing and self-knowledge in higher education teachers: A pilot study through bodyfulness approaches

Work-related stress is a major cause of health problems worldwide. Faculty in educational institutions, including universities, also face high levels of stress, which undoubtedly affects their performance, level of personal satisfaction and wellbeing, and the relationship with students. Training interventions based on embodied learning can promote self-knowledge, emotional regulation and stress reduction, thereby increasing levels of psychological well-being. The present pilot study analyzed the impact of body awareness training in 31 university teachers using a controlled, randomized pre-post experimental design, with two experimental groups and a control group (n = 10). The two interventions were: Hatha Yoga (n = 11) and Dance Movement Therapy/Body Mind Centering (n = 10), which we have termed Body Movement Awareness. Variables related to body awareness, mindfulness, wellbeing, life satisfaction and stress were measured using self-perception tests. Cortisol levels, heart rate variability and sleep quality were also analyzed. Finally, participants' reflections were analyzed according to a qualitative approach. The results showed significant differences between the control group and the Hatha Yoga group in terms of stress reduction and wellbeing. The Body Movement Awareness group exhibited evidence of contributions on self-knowledge, communication and kinesthetic empathy, key elements in the educational field. Despite the inherent limitations of the study, the conclusions are encouraging and open new lines of research from embodied approaches that introduce creative movement and group experience as part of the process of emotional regulation and self-knowledge.

Are some interoceptive sensibility components more central than others? Using item pool visualisation to understand the psychometric representation of interoception

Interoception refers to the processing of stimuli originating within the body and is widely considered a multidimensional construct. However, there remains a lack of consensus regarding the definition and measurement of the subjective, self-reported component, referred to here as interoceptive sensibility. As a contribution to knowledge on the topic, we sought to examine the construct commonality and distinguishability of seven self-report measures of interoceptive sensibility using Item Pool Visualisation (IPV), an illustrative method that locates item pools from within the same dataset and illustrates these in the form of nested radar charts. Adults from the United Kingdom (N = 802) completed seven measures of interoceptive sensibility, and the data were subjected to IPV. Results demonstrated that, of the included measures, the Multidimensional Assessment of Interoceptive Awareness-2 provided the closest and most precise measurement of the core interoceptive sensibility construct (i.e., core of the entire investigated item pool). The Body Awareness Questionnaire and the Private Body Consciousness Scale were also centrally located measures, while the Body Perception Questionnaire and the Body Responsiveness Scale appear to tap more distal aspects of the core construct. We discuss implications for interpreting complicated data patterns using measures of interoceptive sensibility and, more generally, for measuring the construct of interoceptive sensibility.

Relationships between interoceptive sensibility and resting-state functional connectivity of the insula in obsessive-compulsive disorder

Patients with obsessive-compulsive disorder (OCD) exhibit abnormality in their subjective perception of internal sensation, a process known as interoceptive sensibility (IS), as well as altered functioning of the insula, a key neural structure for interoception. We investigated the multivariate structure of IS in 77 OCD patients and 53 controls and examined associations of IS with resting-state functional connectivity (FC) of the insula within the OCD group. For each group, principal component analysis was performed on 8 subscales of the Multidimensional Assessment of Interoceptive Awareness assessing putatively "adaptive" and "maladaptive" aspects of IS. Associations between IS components and insula FC in the OCD group were evaluated using seed regions placed in each of 3 subdivisions of the insula (posterior, anterior dorsal, and anterior ventral). Behaviorally, controls showed a 2-component solution broadly categorized into "adaptive" and "maladaptive" IS, while OCD patients exhibited a 3-component solution. The general tendency to notice or be aware of sensation loaded onto an "adaptive" IS component in controls but loaded onto both "adaptive" and "maladaptive" IS components in OCD. Within OCD, insula FC was differentially associated with distinct aspects of IS, identifying network connections that could serve as future targets for the modulation of IS in OCD.

The Role of the Person Focused IARA Model in Reducing Anxiety and Improving Body Awareness and Illness Management in Diabetics with Acquired Lipodystrophy: A Mixed-Method Study

Background: Lipodystrophy is one of the most frequent complications in people with diabetes following subcutaneous insulin therapy, and poor management can lead to several problems, such as impaired glycemic control and adherence to therapy, anxiety, and depression. Poor injection technique represents the main risk factor for lipodystrophies. In order to enhance the patient’s insulin injection technique to heal lipodystrophy, improve psychological indices, and promote involvement in their health and care, the efficacy of emerging person-centered care called the IARA model was tested. Methods: A total of 49 patients were randomly allocated to the IARA group (Experimental; n = 25) or standard education (Control; n = 24). The following questionnaires were used in a mixed-method design: (i) State Anxiety Scale; (ii) Beck Depression Inventory; (iii) Italian Summary of Diabetes Self-Care Activities. An ad hoc open-ended questionnaire was structured for the qualitative analysis. Finally, photos were taken in order to verify if injection sites were changed until the follow-up at 12 months. The number of patients who participated until the completion of the study was 17 in the IARA and 11 in the Control group. Results: State anxiety was significantly reduced in people who followed IARA to follow-up at 3 and 6 months (p < 0.05). The IARA group also demonstrated better compliance in blood glucose monitoring and foot-care compared to Control at follow-up at 12 months. The management of insulin injections dramatically improved in participants who received IARA intervention. Conclusions: IARA could be considered an effective strategy to improve well-being and compliance in people affected with diabetes mellitus and lipodystrophy complications.

Interoception in Old Age

Emotion regulation in old age was found to be more efficient; seniors seem to focus less on the negative aspects of experiences. Here, we ask, do older individuals regulate their emotions more efficiently or are they numb to the physiological changes that modulate these emotions? Interoception, the perception of physical feelings, influences a person’s mood, emotions, and sense of well-being, and was hardly tested among older adults. We examined the awareness of physiological changes (physiological arousal—blood pressure and heart rate) of 47 older adults, compared to 18 young adults, and their subjective reports of emotional experiences while viewing emotional stimuli. Interoception was decreased in old age. Blood pressure medications had a partial role in this reduction. Moreover, interoception mediated emotional experience, such that low interoception led to lower experiences of changes in physiological arousal. These findings may account for the emotional changes in old age, suggesting a decline in sensitivity with age, which leads to a positive interpretation of information.

Knowing what you feel: Inferior frontal gyrus-based structural and functional neural patterns underpinning adaptive body awareness

BACKGROUND

Heightened body awareness (BA) is conducive for increasing understanding of bodily state and improves individuals' health and well-being. Although there has been cumulative research concentrating on the self-perceived tendency to focus on negatively valenced interoceptive sensations, the specific structural and functional neural patterns underlying BA and their role in the relationship between BA and individual well-being remain unclear.

METHODS

Voxel-based morphometry and whole brain functional connectivity analyses were conducted to examine the structural and functional neural patterns, respectively, in 686 healthy subjects. BA and subjective well-being were assessed using questionnaires.

RESULTS

BA was inversely related to gray matter volume of the right inferior frontal gyrus, opercular part (IFGoperc). Higher BA was correlated with enhanced IFGoperc-precuneus and IFGoperc-anterior supramarginal gyrus connectivities, and with decreased IFGoperc-lateral occipital cortex and IFGoperc-medial frontal cortex connectivities. The inferior frontal gyrus, triangular part (in the fronto-parietal task control network) acted as the hub that linked the sensory/somatomotor network, the default mode network, and the dorsal and ventral attention network. The IFGoperc-precuneus connectivity moderated the association between BA and subjective well-being.

LIMITATIONS

We were unable to rank all the networks by their relative importance, because the absolute weighted value in each module was not calculated.

CONCLUSION

Our findings demonstrated that BA was reflected by specific neural patterns mainly involved in cognitive-affective control, attentional and self-referential processing, as well as multisensory integration, which could offer some references for current therapies (e.g., mindfulness, yoga training) that are dedicated to solving health problems and improving individual well-being.

Relationship between interoceptive sensibility, age, and COVID-19 anxiety during the first national lockdown in the United Kingdom

Objectives: Interoception refers to the multidimensional representation of the internal states of the body, including sensation, appraisal, integration, and regulation. COVID-19 targets internal respiratory, temperature and gastrointestinal systems, thus posing a threat to humans that causes anxiety. Here, we examined the relationship between interoceptive sensibility and COVID-19 anxiety during the first UK national lockdown, when uncertainties surrounding the virus were at their peak.Methods: Between April and July 2020, N = 232 individuals across four age-categories completed questionnaires measuring interoceptive sensibility (BPQ-SF and MAIA-2), an adapted State-Trait-Anxiety Inventory (STAI) to assess COVID-19 anxiety, and a Perceived Quality of Life (QoL) questionnaire.Results: Higher scores on the BPQ-SF were related to higher levels of COVID-19 anxiety, while the MAIA-2 subscales Not Worrying, Attention Regulation, and Trusting of bodily signals were related to lower levels of COVID-19 anxiety. Age was related to lower levels of COVID-19 anxiety yet showed no significant (Bonferroni-corrected) relationship with interoceptive dimensions. Trait anxiety, Not Worrying, perceived quality of work, and COVID-19-related media consumption emerged as significant predictors of COVID-19 anxiety.Conclusion: Findings suggest that interoceptive dimensions differentially relate to COVID-19 anxiety irrespective of age, with implications for managing health anxiety and adaptive behaviour during a pandemic across the lifespan.

Embodied Cognition in Meditation, Yoga, and Ethics-An Experimental Single-Case Study on the Differential Effects of Four Mind-Body Treatments

Yoga is an embodied contemplative practice considered as a path toward long-term well-being, which fosters an integrated processing of bodily and emotional stimuli. However, little is known about how the different components of yoga contribute to these processes. This was the aim of this single-case multiple-baseline study. Herein, we explored how different yoga components affect body awareness, emotion regulation, affectivity, self-compassion, and distress tolerance. Forty-two randomly assigned participants (from initially fifty-seven) completed one of four 8-week treatments: Mantra meditation alone (MA), meditation plus physical yoga (MY), meditation plus ethical education (ME), and meditation plus yoga and ethical education (MYE). Participants had no prior regular yoga or meditation practice. Data were analyzed using visual inspection, effect size estimation, and multilevel modeling. Surprisingly, all four treatments similarly improved body awareness (Tau-U_MA = 0.21 to Tau-U_MY = 0.49), emotion regulation (Tau-U_MYE = -0.43 to Tau-U_ME = -0.52), self-compassion (η² = 0.08), and distress tolerance (η² = 0.13). These effects were maintained until follow-up at 2 and 12 months after the study, even though home practice declined. The MA condition had the least favorable effect on affective experience (Tau-U_MA = -0.14 and 0.07), while the ME condition enhanced valence the most (Tau-U_ME = 0.10) and the MY condition was the most effective in preventing negative affective responses. Although mantra meditation on its own negatively influenced daily affect, it can be assumed as the driving force behind the improvement in the other variables. This points to the central role of meditation in increasing interoception, self-awareness, and embodied processing.

Probing the posture with machine learning provides physiological evidence supporting the enhanced body awareness hypothesis in trait mindfulness

Enhanced body awareness has been suggested as one of the cognitive mechanisms that characterize mindfulness. Yet neuroscience literature still lacks strong empirical evidence to support this claim. Body awareness contributes to postural control during quiet standing; in particular, it may be argued that body awareness is more strongly engaged when standing quietly with eyes closed, because only body cues are available, than with eyes open. Under these theoretical assumptions, we recorded the postural signals of 156 healthy participants during quiet standing in Eyes closed (EC) and Eyes open (EO) conditions. In addition, each participant completed the Freiburg Mindfulness Inventory, and his/her mindfulness score was computed. Following a well-established machine learning methodology, we designed two numerical models per condition: one regression model intended to estimate the mindfulness score of each participant from his/her postural signals, and one classifier intended to assign each participant to one of the classes “Mindful” or “Non-mindful.” We show that the two models designed from EC data are much more successful in their regression and classification tasks than the two models designed from EO data. We argue that these findings provide the first physiological evidence that contributes to support the enhanced body awareness hypothesis in mindfulness.
