Interpretable principal component analysis for multilevel multivariate functional data.

Many studies collect functional data from multiple subjects that have both multilevel and multivariate structures. An example of such data comes from popular neuroscience experiments where participants' brain activity is recorded using modalities such as electroencephalography and summarized as power within multiple time-varying frequency bands within multiple electrodes, or brain regions. Summarizing the joint variation across multiple frequency bands for both whole-brain variability between subjects, as well as location-variation within subjects, can help to explain neural reactions to stimuli. This article introduces a novel approach to conducting interpretable principal components analysis on multilevel multivariate functional data that decomposes total variation into subject-level and replicate-within-subject-level (i.e., electrode-level) variation and provides interpretable components that can be both sparse among variates (e.g., frequency bands) and have localized support over time within each frequency band. Smoothness is achieved through a roughness penalty, while sparsity and localization of components are achieved by solving an innovative rank-one based convex optimization problem with block Frobenius and matrix $L_1$-norm-based penalties. The method is used to analyze data from a study to better understand reactions to emotional information in individuals with histories of trauma and the symptom of dissociation, revealing new neurophysiological insights into how subject- and electrode-level brain activity are associated with these phenomena.

Are the presence of asthma and the COVID-19 infection associated with behavioral changes in Lebanese adolescents?

BACKGROUND: Little evidence is available about psychological stressors in Lebanese asthmatic adolescents, where health-risk behaviors are a serious threat to public health. In addition, the COVID-19 epidemic has had a substantial influence on adolescents' mental health globally, especially in Lebanon, where the ongoing economic and political challenges have largely impacted their psychological well-being. This study aimed to explore the association of asthma and the COVID-19 infection with behaviors among Lebanese adolescents. METHODS: Data were collected in July 2023, using the snowball sampling technique. Inclusion criteria for participation in the study included being of a resident and citizen of Lebanon and aged 12-18 years. Behavioral problems were assessed using the Youth Self-Report (YSR) scale, which yields nine subscales (anxious/depressed, withdrawn/depressed, somatic complaints, social problems, thought problems, attention problems, rule-breaking behavior, aggressive behavior, and other problems) and a total score. RESULTS: Asthma was significantly associated with somatic complaints (Beta [ß] = 2.98), attention problems (ß = 0.01), and other behavioral problems (ß = 0.68). Having contracted the COVID-19 infection, compared to healthy asymptomatic state (ß = 1.55), was significantly associated with more anxious behaviors. In the case of stratifying the analysis in terms of gender, the results showed that the presence of asthma was significantly associated with more social behaviors (ß = 3.31), thought problems (ß = 2.91), attention problems (ß = 0.02), other behavioral problems (ß = 1.71), and total behavioral problems (ß = 5.71) in males. In case stratifying the analysis as to school type, the presence of asthma was significantly associated with more somatic complaints (ß = 2.77) in participants from private schools whereas it was significantly associated with more total behavioral problems (total YSR scores) (ß = 5.05) in participants from public schools. CONCLUSION: It is confirmed that asthma and psychiatric disorders are interconnected, so it would be of great importance to include screening through a psychological intervention in treating asthmatic adolescents by means of (1) recognizing factors affecting patients' mental health, and (2) regulating uncontrolled behaviors that can exacerbate symptoms in order to avoid the future morbidity.

A meta-analysis of the association between shame and dissociation.

Shame and dissociation have been implicated theoretically and empirically in trauma exposure and its sequelae, with shame understood as an intense negative emotion and dissociation as a reaction to intense negative emotions. Understanding the connection between shame and dissociation is important for theory and practice; however, the strength of this association remains unclear. For example, in therapy, both shame and dissociation serve as a barrier to engaging with emotion. Theoretically, these two states should be distinct, as one (dissociation) confers low affective intensity and the other (shame) high intensity. The present meta-analysis focused on the magnitude of the association between these two phenomena and investigated the extent to which gender, trauma exposure, psychiatric comorbidities, and demographic characteristics influence this association given their independent links to shame and dissociation. An initial search of six databases identified 151,844 articles. Duplicates were removed, and additional articles were excluded based on abstract and title screening. After contacting authors for missing data, a full-text screen yielded 25 articles for the present analysis. The results indicate that shame and dissociation were moderately correlated (k = 33, n = 4,705), r = .42, 95% CI [.35, .48], p < .001, but no clear clinical moderators emerged. Despite this association, very few studies utilized experimental designs to examine the association between these constructs. Future research should focus on experimental study designs to investigate the extent to which shame induces dissociation or vice versa.

Introduction to the Special Issue: Network Analysis of Traumatic Stress.

Network analysis has emerged as a promising new statistical methodology for traumatic stress studies. The present special issue of the Journal of Traumatic Stress amalgamates the reports of 10 studies that employed network analysis to further the field's understanding of traumatic stress. The current issue includes reports of network analyses that sought to better understand the impact of different kinds of traumatic events, including childhood and gender-based trauma exposure, on PTSD symptomatology as defined under the DSM-5 and ICD-11, and examined the relation between PTSD symptoms and trauma-related dissociative experiences as well as the impact of psychological treatment on trauma recovery. A variety of research designs from a diverse group of international samples were employed, including concurrent, longitudinal, experience-sampling, and treatment outcome studies. Finally, a commentary on the articles included in this special issue was provided by Dr. Carl Weems.

When stress becomes the new normal: Alterations in attention and autonomic reactivity in repeated traumatization.

There is need for further work clarifying attention-physiology interactions by degree of exposure to early victimization, as it is clear that cumulative trauma in childhood, that is, polyvictimization, may have lasting effects on the stress response that differ from those of acute traumatization. The present study examined relationships between baseline and task-related physiology (indexed by respiratory sinus arrhythmia [RSA] and heart rate [HR], respectively), and attention biases (via the dot probe task), in 63 community-dwelling adult women stratified on the basis of self-reported exposure to multiple types of childhood interpersonal victimization (i.e., sexual, physical, and emotional abuse). Consistent with hypotheses, a pattern of threat hypervigilance was found in the single victimization group, while threat avoidance was found in the polyvictimization group. Additionally, avoidance of threat in the polyvictimized group was associated with lower baseline RSA. Moderation analyses indicated that condition-wise HR moderated the relationship between level of exposure and attention biases in the high-threat condition. The present findings may clarify basic regulatory mechanisms that play a role in lifetime revictimization in individuals with cumulative childhood trauma exposure and may have implications for their prognostic and therapeutic outcomes.

Neural correlates of heart rate variability in PTSD during sub- and supraliminal processing of trauma-related cues.

BACKGROUND: Posttraumatic stress disorder (PTSD) is characterized by dysregulated arousal and altered cardiac autonomic response as evidenced by decreased high-frequency heart rate variability (HF-HRV), an indirect measure of parasympathetic modulation of the heart. Indeed, subtle threatening cues can cause autonomic dysregulation, even without explicit awareness of the triggering stimulus. Accordingly, examining the neural underpinnings associated with HF-HRV during both sub- and supraliminal exposure to trauma-related cues is critical to an enhanced understanding of autonomic nervous system dysfunction in PTSD. METHODS: We compared neural activity in brain regions associated with HF-HRV in PTSD (n = 18) and healthy controls (n = 18) during exposure to sub- and supraliminal processing of personalized trauma-related words. RESULTS: As compared to controls, PTSD exhibited decreased HF-HRV reactivity in response to sub- and supraliminal cues. Notably, during subliminal processing of trauma-related versus neutral words, as compared to controls, PTSD showed decreased neural response associated with HF-HRV within the left dorsal anterior insula. By contrast, during supraliminal processing of trauma-related versus neutral words, decreased neural activity associated with HF-HRV within the posterior insula/superior temporal cortex, and increased neural activity associated with HF-HRV within the left centromedial amygdala was observed in PTSD as compared to controls. CONCLUSIONS: Impaired parasympathetic modulation of autonomic arousal in PTSD appears related to altered activation of cortical and subcortical regions involved in the central autonomic network. Interestingly, both sub- and supraliminal trauma-related cues appear to elicit dysregulated arousal and may contribute to the maintenance of hyperarousal in PTSD.

Autonomic Arousal and Emotion in Victims of Interpersonal Violence: Shame Proneness But Not Anxiety Predicts Vagal Tone.

The redefinition of posttraumatic stress disorder (PTSD) in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, has highlighted a range of posttraumatic affects beyond fear and anxiety. For survivors of interpersonal violence, shame has been shown to be an important contributor of self-reported symptomatology. Although biological models of PTSD emphasize physiological arousal secondary to fear and anxiety, evidence suggests that shame might be related to increased arousal as well. This study tested the contributions of anxiety, fear, and shame to autonomic arousal in a sample of female victims (N = 27) of interpersonal violence with PTSD. Shame proneness was the only significant correlate of autonomic arousal during a trauma reminder paradigm. These findings indicate that shame corresponds to important indicators of changes to the autonomic nervous system that have previously been assumed to be fear related.

Psychophysiological predictors of working alliance among treatment-seeking women with complex trauma exposure.

Research has established that trauma-related symptoms may impede the formation of a strong working alliance (i.e., interpersonal connection, trust, and shared goals between therapist and client). As the alliance is critical in trauma-focused therapy, we studied how clients' pretherapy factors, including symptoms and psychophysiological arousal, predict treatment alliance. We examined symptoms and physiological responses in 27 women who had exposure to extreme interpersonal violence; all of whom were enrolled in therapy. All had symptoms consistent with a diagnosis of posttraumatic stress disorder. Clients completed measures of working alliance and were assessed before and after treatment on measures of symptoms and autonomic arousal. Autonomic assessment included measures of skin conductance and respiratory sinus arrhythmia (RSA), taken during baseline, while viewing positive and then trauma-related slides, and during recovery. Higher alliance ratings were predicted by lower pretherapy skin conductance during trauma slides (r = -.41, p = .049) and recovery (r = -.44, p = .047) and higher RSA during baseline (r = .47, p = .027) and positive slides (r = .43, p = .044). Findings remained significant even after partialling pretherapy symptoms. These data on a high-need but understudied population suggest that sympathetic and parasympathetic arousal may help traumatized clients effectively engage in therapy, further supporting the role of parasympathetic activity in social engagement.

Can perpetrators discern survivors from voice?

Background: Research has shown that potential perpetrators and individuals high in psychopathic traits tend to body language cues to target a potential new victim. However, whether targeting occurs also by tending to vocal cues has not been examined. Thus, the role of voice in interpersonal violence merits investigation.Objective: In two studies, we examined whether perpetrators could differentiate female speakers with and without sexual and physical assault histories (presented as rating the degree of 'vulnerability' to victimization).Methods: Two samples of male listeners (sample one N = 105, sample two, N = 109) participated. Each sample rated 18 voices (9 survivors and 9 controls). Listener sample one heard spontaneous speech, and listener sample two heard the second sentence of a standardized passage. Listeners' self-reported psychopathic traits and history of previous perpetration were measured.Results: Across both samples, history of perpetration (but not psychopathy) predicted accuracy in distinguishing survivors of assault.Conclusions: These findings highlight the potential role of voice in prevention and intervention. Gaining a further understanding of what voice cues are associated with accuracy in discerning survivors can also help us understand whether or not specialized voice training could have a role in self-defense practices.

We examined whether listeners with history of perpetration could differentiate female speakers with and without assault histories (presented as rating the degree of 'vulnerability' to victimization).Listeners' higher history of perpetration was associated with higher accuracy in differentiating survivors of assault from non-survivors.These findings highlight that voice could have a crucial role in prevention and intervention.

Trauma-Informed Yoga: A Capacity Building and Wellness Strengthening Intervention for Female Survivors of Intimate Partner Violence and Affiliative Staff.

This evaluation examines the impacts of Exhale to Inhale's trauma-informed yoga (TIY) on stress, somatic complaints, and self-efficacy among female survivors of intimate partner violence (IPV) and affiliated staff in community-based domestic violence agencies. A two-phase study design was employed, the first of which collected data from in-person group classes and the second from remotely taught classes due to COVID-19 safety restrictions. Collected over 3 years, 526 female survivors (n = 361) and staff (n = 165) from 66 domestic violence agencies completed surveys revealing improved stress, somatic complaints, and self-efficacy following a single TIY session. TIY serves as a capacity-building intervention that is suitable and adaptable for survivors of IPV and the staff at domestic violence agencies.

Understanding Capacities for Interpersonal Distress Tolerance in Individuals with Suicide Ideation.

INTRO: The relationship between suicide ideation (SI) and distress tolerance (DT) is characterized by inconclusive results. The current study aimed to test the association between tolerance for interpersonal distress and SI in light of the Interpersonal-Psychological Theory of Suicide. METHODS: 194 participants ranging in SI severity were recruited via Amazon Mechanical Turk and completed a cognitive distress task (Distress Tolerance Task) and an interpersonal distress task (CyberBall) to assess (1) the association between SI severity and persistence with the tasks, and (2) self-reported psychological distress associated with the tasks. RESULTS: A series of multilevel model analyses showed that increased SI predicted greater persistence with the interpersonal-distress task versus the cognitive distress task. In addition, higher SI predicted more distress during the interpersonal task. CONCLUSIONS: Individuals with higher SI levels demonstrated a greater capability to persist with the interpersonal distress, despite feeling psychologically worse. These findings further support the central role of interpersonal needs in SI by emphasizing the importance of operationalizing DT in a manner that is relevant to suicide desire.

SI is associated with persisting longer in interpersonally distressing situations.SI is also associated with higher levels of distress following social exclusion.In SI research the specific type of distress needs to be accurately operationalized.

Shame-induced dissociation: An experimental study of experiential avoidance.

OBJECTIVE: The study experimentally investigated shame-induced dissociation, and to what extent that process was associated with exposure to childhood maltreatment. METHOD: Using a shame-related script-driven imagery paradigm and mirror-viewing task, 50 female participants from the community recalled two shame-related and two neutral autobiographical memories, after which they listened to recordings of themselves retelling the narratives looking in a mirror or at a black curtain (i.e., mirror-viewing task). RESULTS: Shame-related memories compared to neutral memories resulted in higher rates of dissociation. The relationship between shame and dissociation was significantly moderated by experiential avoidance or avoidance of unwanted cognitive and affective reactions. In contrast to previous research, looking in the mirror and childhood maltreatment severity did not predict dissociative responses. CONCLUSIONS: The strong relationship between shame and dissociation suggests the importance of monitoring patients' affect and behavior when revisiting shame-related memories, to not reinforce dissociative reactions and inadvertently foster treatment resistance.

Behavioral and Biological Indicators of Risk and Well-Being in a Sample of South African Youth.

Self report measures have been widely used in research to illustrate high rates of exposure to violence among youth in trauma-saturated regions, such as Cape Town, South Africa. To better understand the risk and resilience factors of youth who have been exposed to, witnessed, or directly experienced violence, the current study used a multi-method assessment in a naturalistic setting that included heart rate variability (an index of regulatory flexibility and cardiovascular health), a computerized risk-taking task, and self report measures. Youth (N = 83) from Cape Town, South Africa, participated in a psychobiological assessment. Findings suggest elevated age-adjusted heart rate variability compared to age related norms, which is indicative of overregulation of behavior and emotion. Additionally, youth, all of whom had witnessed or experienced violence at least once, demonstrated a low risk taking and reward seeking propensity. Low risk taking in the context of elevated heart rate variability may reflect youth's affective and behavioral inhibition, suggestive of stress among children who have an overgeneralized threat response. These results both demonstrate the feasibility of psychophysiological research in community youth settings, and counter the traditional narrative that there is an overarching lack of capacity to regulate and a high propensity to risk in violence-exposed youth.

Growing Up on the Edge: A Community-Based Mental Health Intervention for Children in Gaza.

The Gaza Strip is a notoriously high-conflict area, but few large-scale studies have examined the rates of psychiatric distress and emotional/behavioral problems among Gaza youth, and there are few trauma-informed, scaleable intervention options. Studies in existence have used smaller samples or have examined focal problems such as posttraumatic stress disorder (PTSD) or aggression. Here, we examine the mental health burden of young individuals (ages 8-13) in Gaza across a broad range of symptoms, and demonstrate the impact of a community-based, trauma-informed program, Eye to the Future. At the outset of this supportive youth program, over 2000 children and adolescent youth and their parents reported on child well-being using standardized measures with established global norms (the Child Behavior Checklist and Youth Self Report). These measures examine symptoms broadly (e.g. anxiety, depression, social problems, attention problems, aggression, etc.). Relative to U.S. population estimates, children in Gaza had between 2.5- and 17-times higher point prevalence of clinical mental health problems. The most significant clinical concern was anxiety, but overall, their symptoms were not confined to posttraumatic stress as a disorder and were instead broadly dispersed. However, these concerns were responsive to intervention: over the course of a six-month community psychosocial program, symptoms ameliorated, with approximately 50-70% showing reliable improvement at post-program (varying by measure). These gains were maintained in a 9-month follow-up. Future work should consider the broader mental health impact, beyond PTSD and aggression, and incorporate community supports into addressing mental health among children in the region.

To thine own self be true: interoceptive accuracy and interpersonal problems.

BACKGROUND: Borderline Personality Disorder involves strong interpersonal disruptions, often associated with early maltreatment. However, the individual capacities which alter BPD-related interpersonal problems are unclear. Here, we examine two contributors to interpersonal functioning: interoceptive accuracy and parasympathetic activity. Interoceptive accuracy is the ability to correctly perceive body states, such as how quickly one's heart is beating, and has been associated with emotional experience and various crucial social capacities. Similarly, parasympathetic activity is related to social processing and inhibition of impulses. As such, both may contribute to BPD interpersonal symptoms, albeit different types of interpersonal problems. METHOD: Sixty-five individuals completed the Inventory of Interpersonal Problems and the Millon Clinical Multiaxial Inventory followed by a task to assess interoceptive accuracy, the heart rate monitoring task, in which participants counted their heartbeats while concurrent physiological data was recorded; and an assessment of vagal tone, used as an index of regulatory flexibility. RESULTS: Participants who reported poor interpersonal boundaries, consistent with borderline personality disorder styles, had worse interoception, whereas those high in aggression had lower vagal tone. Borderline personality symptoms overall were related to IA and significantly to vagal tone. CONCLUSIONS: These findings suggest that interoceptive accuracy is associated with interpersonal problems, where people are overly influenced or enmeshed with others, possibly to compensate for the absence of their physical and emotional awareness.

Beyond PTSD: Client presentations of developmental trauma disorder from a national survey of clinicians.

OBJECTIVE: The emergence of updated Diagnostic and Statistical Manual of Mental Disorders (5th ed. [DSM-5]; American Psychiatric Association, 2013) criteria for posttraumatic stress disorder (PTSD), which includes modified criteria for young children, raises questions regarding the need for developmentally appropriate standalone psychiatric diagnosis encompassing complex trauma presentations in children. The present study addresses these questions by examining how DSM-5 PTSD and proposed developmental trauma disorder (DTD) diagnoses relate to functional impairment and trauma exposure using clinician-report surveys. METHOD: We surveyed psychotherapists across the United States, and asked them to report on the symptom characteristics, functional impairment, and trauma exposure of children, adolescents, and young adults under their care (n = 210; age range = 2-21). We fit symptom data to the draft criteria for (1) DTD, a proposed trauma diagnosis for children and (2) existing criteria for adult and child/preschool PTSD. RESULTS: Results indicated that comorbidity between DTD and PTSD was high (52.4% and 59.9% for adult and child/preschool criteria, respectively). Comorbid DTD/PTSD and DTD-alone groups had more functional domains impacted and greater exposure to some types of trauma relative to the other groups. CONCLUSIONS: These findings speak to the relationship between trauma complexity and wide-ranging symptom presentations, provide support for research and clinical emphasis on a developmentally informed diagnosis, and may support existing treatment approaches.

Physical health problems after single trauma exposure: when stress takes root in the body.

Research has established that chronic stress, including traumatic events, leads to adverse health outcomes. The literature has primarily used two approaches: examining the effect of acute stress in a laboratory setting and examining the link between chronic stress and negative health outcomes. However, the potential health impact of a single or acute traumatic event is less clear. The goal of this literature review is to extend the literature linking both chronic trauma exposure and posttraumatic stress disorder to adverse health outcomes by examining current literature suggesting that a single trauma may also have negative consequences for physical health. The authors review studies on health, including cardiovascular, immune, gastrointestinal, neurohormonal, and musculoskeletal outcomes; describe potential pathways through which single, acute trauma exposure could adversely affect health; and consider research and clinical implications.

Using Psychedelics With Therapeutic Intent Is Associated With Lower Shame and Complex Trauma Symptoms in Adults With Histories of Child Maltreatment.

BACKGROUND: Child maltreatment negatively affects the formation of internal schemata of self and other during development, leading to negative adaptations in self-concept and social cognition. Clinical reports suggest the efficacy of psychedelics in treating the psychopathological sequelae of child maltreatment. Altering maladaptive schemata of self and other implicated in negative self-concept and impaired social cognition may be a central mechanism for reducing posttraumatic stress symptoms. AIMS: This study aims to assess whether psychedelic use moderates the relationships between child maltreatment and self-concept, social cognition, and posttraumatic stress symptoms. METHOD: An online survey was completed by 166 participants and included measures of maltreatment exposure and severity, history of intentional therapeutic psychedelic use, posttraumatic stress symptoms, internalized shame, and facial emotion recognition. RESULTS: Child maltreatment significantly correlated with posttraumatic stress symptoms (r = .26 and r = .20, p < .01) and internalized shame (r = .18, p < .05). Of all maltreatment subtypes, emotional abuse and neglect most strongly correlated with complex trauma symptoms (r = .32, p < .001) and internalized shame (r = .31, p < .001). Participants with a history of intentional therapeutic psychedelic use reported significantly lower complex trauma symptoms (d = 0.33, p < .05) and internalized shame (d = 0.35, p < .05) despite similar histories of maltreatment. Differences in complex trauma symptoms (d = 0.66, p < .01) and internalized shame (d = 0.80, p < .001) were largest for participants with a history of more than 5 occasions of intentional therapeutic psychedelic use. A history of more than 5 occasions of intentional therapeutic psychedelic use significantly moderated the relationship between emotional abuse and neglect and complex trauma symptoms (p < .01). No associations were found between maltreatment or psychedelic use and facial emotion recognition. CONCLUSION: These findings demonstrate that using psychedelic drugs with therapeutic intent is associated with lower levels of complex trauma symptoms and internalized shame in individuals with histories of child maltreatment. Psychedelic use may have therapeutic benefit in treating the posttraumatic sequelae of child maltreatment.

Mapping alexithymia: Level of emotional awareness differentiates emotion-specific somatosensory maps.

BACKGROUND: Emotions have been associated with culturally universal and distinct bodily sensation "maps". Despite this knowledge, to date few studies have explored emotion-specific topography along clinically relevant dimensions, such as alexithymia. OBJECTIVE: We aimed to investigate emotion-specific topographies among individuals exposed to childhood maltreatment or neglect with absent (n = 51) or with probable (n = 46) alexithymia in adulthood, as defined by scores on the Toronto Alexithymia Scale (TAS-20). PARTICIPANTS AND SETTING: Ninety eight adult participants with exposure to childhood maltreatment or neglect were recruited to complete an online survey. METHODS: Using the well-validated emBODY tool (Nummenmaa et al., 2014), participants reported on their somatic experience of 17 emotions. RESULTS: Random effects analyses revealed topographically distinct bodily sensation t-maps that differentiated participants who endorsed probable alexithymia from those who did not (p-FDR < .05). Consistent with our a priori hypothesis, the probable alexithymia group reported a muted, diffuse and undifferentiated pattern of emotion-specific bodily sensation, whereas the non-alexithymia group reported a more distinct and localized pattern. CONCLUSIONS: These results suggest that difficulty identifying and labeling emotions, as observed in alexithymia, may arise, in part, from an altered perception of somatic activation. It is well-established that childhood maltreatment predicts the development of alexithymia symptoms. The preliminary findings presented here expand our working understanding of the physical markers of childhood trauma, which may be used in practice to aid detection and to monitor treatment outcomes.

Hurts so good: Pain as an emotion regulation strategy.

In the field of emotion regulation studies, cognitive reappraisal has been established as the preferred strategy for coping with painful negative feelings. For some, however, asking them to think more about an already distressing situation can be quite literally "like pulling teeth." Indeed, many people voluntarily cause themselves physical pain during upsetting situations (e.g., getting a deep tissue massage after a stressful week or hitting a punching bag when angry); however, there is currently little empirical evidence of the relative effectiveness of such behaviors. The present study tested two primary hypotheses: (a) some people will choose to inflict pain to regulate negative emotional states; and (b) pain provides effective short-term relief from negative emotion. The findings from these two studies demonstrate that, given the opportunity, participants will choose to use physical pain in addition to other strategies, like reappraisal or distraction, to cope with various sources of negative emotion. We further show that physical sensation in general, and pain in particular, are equally effective in coping with negative emotion. These results suggest a reconsideration of the dominance of cognitively based emotion regulation. We discuss the implication that benign physical pain may be a broadly effective and underrecognized coping strategy. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
