Chronic Pain Personification Following Child Abuse: The Imprinted Experience of Child Abuse in Later Chronic Pain

Chronic pain and comorbid posttraumatic stress disorder: Potential mechanisms, conceptualizations, and interventions

Posttraumatic stress disorder (PTSD) is a common comorbidity to chronic pain, among others due to potentially shared posttraumatic origin. There has been growing interest in this field in the past decades, also providing some important studies to support our understanding of this comorbidity and how to address it in clinical practice. However, there are still important questions, particularly regarding the potentially shared vulnerabilities, mutually maintaining mechanisms, and how to best treat this comorbidity. This article provides a brief and up-to-date review of what we argue to be some of the most important studies within the field of chronic pain and comorbid PTSD and will discuss some of the current challenges and ways forward.

The Potential of a Robot Presence in Close Relationship to Influence Human Responses to Experimental Pain

Pain management is a critical challenge in healthcare, often exacerbated by loneliness and emotional distress. This study investigated the potential of a communication robot, Moffuly, to reduce pain perception and influence hormonal responses in a controlled experimental setting. Nineteen healthy participants underwent heat pain stimulation under two conditions: with and without robotic interaction. Pain levels were assessed using the Short-form McGill Pain Questionnaire and the Visual Analogue Scale, while mood and mental states were evaluated through established questionnaires including the Profile of Mood States, Hospital Anxiety and Depression Scale, and Self-Rating Depression Scale. Hormonal changes, including cortisol, growth hormone, oxytocin, estradiol, and dehydroepiandrosterone-sulfate, were measured from blood samples collected at key time points. The results demonstrated significant reductions in subjective pain and improvements in mood following robotic interaction. These effects were accompanied by favorable hormonal changes, including increased oxytocin and decreased cortisol and growth hormone levels. The findings suggest that robotic interaction may serve as an innovative approach to pain management by addressing both physiological and psychological factors. This study highlights the potential of robotics to complement traditional therapies in alleviating pain and enhancing emotional well-being. By mitigating emotional distress and loneliness, robotic interventions may enhance existing pain therapies and offer innovative solutions for resource-limited healthcare systems.

Intergenerational associations between childhood maltreatment, post-traumatic stress symptoms, and chronic pain in young adult offspring and their parents

Findings have revealed a strong link between exposure to child maltreatment (CM) and later chronic pain. Concurrently, other findings have been grounded in the understanding that CM consequences may not end with the exposed individual, rather, they extend to their offspring. However, little is known regarding the possible intergenerational transmission of chronic pain following CM. This study examines whether chronic pain among parents and their young adult offspring may be associated with parental exposure to CM. Three hundred ninety-three parent-offspring dyads (parents' mean age = 58, SD = 5.91 years; offspring's mean age = 27, SD = 3.91 years) completed self-report questionnaires, assessing CM (CTQ), posttraumatic stress (PTS) and disturbances in self-organisation (DSO) symptoms (ITQ), and chronic pain. CM was associated with chronic pain mediated by DSO symptoms among parents (indirect effect = 0.77; p = 0.007) and PTS symptoms among offspring (indirect effect = 0.285; p = 0.005). Offspring chronic pain was significantly associated with parental CM through two intergenerational paths: the mediation of parents' DSO symptoms and chronic pain (indirect effect = 0.298; p = 0.011), and through parents' PTS symptoms and offspring's PTS symptoms (indirect effect = 0.077; p = 0.004). This study's findings support the relevance of the intergenerational transmission of chronic pain following parental exposure to CM. Furthermore, the findings reveal complex PTS symptoms as a possible underlying mechanism for the intergenerational associations of chronic pain following CM.

Mechanisms Underlying Sex Differences in Temporomandibular Disorders and Their Comorbidity with Migraine

Sexual dimorphism in temporomandibular disorders (TMDs) and their comorbidity with migraine are important phenomena observed in clinics. TMDs are the most prevalent orofacial pain conditions with jaw joint and masseter muscle dysfunction. Migraine is the predominant headache commonly associated with TMDs. Women much more often suffer from this orofacial pain than men. However, currently, there is no gender-specific therapy for such pain conditions. Understanding the pathophysiological mechanisms behind sex differences in TMDs as well as their comorbidity with migraines is essential for developing novel approaches for gender-specific treatment of TMDs and related orofacial pain comorbidity. In this review, we summarize recent research progress regarding sex differences in TMDs, focusing on the underlying mechanisms including craniofacial anatomy, hormonal regulation, and roles of opioids, transient receptor potential channels, and endocannabinoid systems. We also discuss the mechanisms of comorbid TMDs and migraine. The information covered in this review will provide mechanistic insights into sex differences in TMDs and their comorbidity with migraine, which could aid in developing effective treatment strategies for the overlapping orofacial pain condition.

Peritraumatic Pain in Child Maltreatment: A Systematic Literature Review

Extensive research has been conducted on the link between trauma, child maltreatment (CM), and chronic pain. Although the risk of suffering from chronic pain among CM survivors has been established, much less is known about the experience of pain during CM incidents or whether such peritraumatic pain sensations are associated with later chronic pain. This scoping review was conducted to synthesize the existing literature on pain during and a short time following CM (i.e., peritraumatic pain). Utilizing the preferred reporting items for systematic reviews and meta-analyses guidelines, the current review included 11 manuscripts, which met the following criteria: (a) refer to physical pain experienced during or a short time after CM, (b) were published in peer-reviewed journals, and (c) were written in English. The review demonstrated that most of the included studies were not intentionally focused on peritraumatic pain, the majority used qualitative research methods, and all were cross-sectional. Furthermore, although validated questionnaires are available, most of the studies did not utilize such measures. Those that intentionally reported pain demonstrated its high intensity and prevalence in CM incidents, indicating that pain is inherently embedded in the experience of maltreatment. The findings spotlight an underdeveloped research realm on a phenomenon that may hold significant empirical, clinical, and legal implications. Research endeavors should initiate interdisciplinary bodies of knowledge to establish well-validated research methodologies that properly quantify peritraumatic pain in trauma and CM.

Exploring downstream effects of gender roles in healthcare decision-making and relationships within systems: A cross-sectional analysis of openness to treatment in pediatric headache

OBJECTIVE

Socio-culturally defined identity factors present significant and often understudied influences on the experience, management, and treatment of chronic pain. For instance, there exist societal narratives about how males and females are expected to experience and express pain. Such gender roles may impact youth and caregiver openness to individual multidisciplinary treatments for pediatric headache.

METHODS

In this cross-sectional study, participants (N = 1087 youth/caregiver dyads, Mage = 14.5 years, 71% female, 97% cisgender, 77% White) completed a series of questionnaires, including Openness to Headache Treatment (OHT), upon presenting for initial multidisciplinary evaluation of chronic headache. Pearson correlations, independent samples t-tests and hierarchical regressions were used to analyze potential gender differences in youth and caregiver openness, as well as its relationships with pain-related and psychological factors.

RESULTS

Overall, female youth and their caregivers were more open to headache treatment, broadly and for individual interventions, when compared to male counterparts. Caregiver distress related to their child's headaches (i.e., fear and avoidance) was significantly correlated with openness in female youth and their caregivers, but not males.

CONCLUSION

Gendered patterns in healthcare decision-making in youth and caregivers provide insight on individual, societal, and systemic gender bias.

The Complex Interplay between BDSM and Childhood Sexual Abuse: A Form of Repetition and Dissociation or a Path Toward Processing and Healing?

In this theoretical paper the authors explore the connections between BDSM (i.e., practices involving bondage, discipline, dominance, submission, sadism, masochism) and CSA (childhood sexual abuse) in order to investigate the potential unconscious mechanisms at play and the therapeutic functions of BDSM practices among CSA victims. Drawing on the embodiment framework, the authors address how BDSM may serve as a form of unconscious repetition of traumatic experiences for certain CSA victims, with the aim of processing trauma and healing. A review of the empirical evidence regarding the links between BDSM and CSA trauma, along with the potential of BDSM to trigger trauma and elicit dissociation, guilt, or shame, is conducted. Finally, BDSM practices are reviewed through the concept of trauma-play, which involves deliberate rescripting. In short, the complex relationship between BDSM and CSA is highlighted, as well as its implications for understanding and potentially addressing trauma experiences in therapy.

Sex in the Shadow of Child Sexual Abuse: The Development and Psychometric Evaluation of the Post-Traumatic Sexuality (PT-SEX) Scale

Sexual-related post-traumatic stress symptoms (sexual-related PTSS) refers to the traumatic reactions that are replicated during sexual activity among survivors of child sexual abuse (CSA). However, the construct of sexual-related PTSS have been adapted from clinical work with survivors, and research with limited examination of the scales themselves. Given this gap, the current study offers the development of a new measure (PT-SEX) that examines sexual-related PTSS. The study was conducted online, among two convenience samples of women survivors of CSA (study 1 included 451 women and study 2 included 330 women). Six reliable PT-SEX factors emerged from Study 1: Dissociation during sex, intrusiveness during sex, shame and guilt in regard to sexual aspects, pleasing the other during sex, interpersonal distress, and hypervigilance during sex. Study 2 revealed survivors of CSA had significantly higher sexual-related PTSS levels as compared to participants without such a history. Also, post-traumatic stress disorder and sexual-related PTSS made unique and unshared contributions to the observed data, including sexual self-esteem, sexual motives, relationship satisfaction, compulsive sexual behavior, and mental health. CSA significantly moderated the associations between sexual-related PTSS and sexual self-esteem, sexual motivations of self-affirmation and coping, and depression and anxiety. Findings from the current study show that over time, the trauma of CSA seems to be implicated in survivors' sexual experience. As sexual difficulties are accompanied by sexual-related PTSS, these symptoms are unlikely to resolve by trauma-focused therapy and must be actively targeted in therapy.

Negative and positive personification of multiple sclerosis: Role in psychological adaptation

OBJECTIVE

Illness personification theory posits that individuals suffering from chronic illness ascribe human characteristics to their illness, which impacts their adaptation. Whereas negative or malevolent personification of chronic illness derails adaptation, positive or benevolent personification yields a complex pattern with aspects of adaptation. This study aimed to examine, for the first time, the role of personification of multiple sclerosis (MS).

METHOD

A two-wave design was implemented with 90 people with MS (PwMS) at T1 (2019) and 60 at T2 (2020). The Ben-Gurion University Illness Personification Scale (BGU-IPS) was administered alongside a host of adaptation-related variables relating to salutogenic, psychological, psychopathological and health aspects. The intent was to replicate the 2-factor structure of the IPS and examine associations with adaptation variables.

RESULTS

The 2-factor structure of the BGU-IPS was replicated by Principal Component Analysis and Confirmatory Factor Analysis, with good to excellent test-retest reliability. for negative (ICC = 0.81; p < .001) as well as for positive personification scale (ICC = 0.76; p < .001). Negative personification was associated with elevated levels of psychological and psychopathological aspects, as well as low levels of heath related-adaption and salutogenic adaption. Positive personification was associated with salutogenic adaption. In addition, exploratory longitudinal analyses revealed that negative personification at T1 significantly predicted anxiety, physical problems, pain frequency and fatigue frequency at T2, while controlling for the variable's T1 measurements, while positive personification at T1 significantly predicted intolerance of uncertainty at T2.

CONCLUSION

The findings depict negative personification as a risk factor for adaptation in MS and call for a detailed exploration of the meaning of positive personification.

A Scoping Review and Proposed Framework for Coping in Youth With a History of Psychological Trauma and Chronic Pain

OBJECTIVE

Psychological trauma (e.g., abuse, neglect) and posttraumatic stress symptoms (PTSS) commonly occur in pediatric pain populations and may be related to various maladaptive coping strategies, which may in turn affect short- and long-term pain-related outcomes in youth. Accordingly, the current scoping review and conceptual framework seeks to identify important gaps in the field's current understanding of how coping impacts outcomes in youth who have experienced trauma/PTSS and pediatric chronic pain and explores avenues for future investigation.

METHODS

A scoping review of the literature was performed in Medline, Embase, Cochrane Library, PsycInfo, and Sociological Abstracts. Eligibility criteria included pediatric populations experiencing chronic pain, trauma, adverse childhood events, and/or PTSS and associated coping mechanisms. Nine research papers were selected and used to support the conceptual framework. The framework builds upon the work of Compas et al.'s' model of control-based coping (Compas et al., 2006; Compas & Harding Thomsen, 1999) and outlines the potential effects of trauma and/or PTSS and pain on coping and pain-related outcomes (e.g., pain chronicity, functional outcomes) in pediatric chronic pain populations.

RESULTS

A history of chronic pain and psychological trauma and/or PTSS in youth may contribute to increased risk for maladaptive coping and in turn, poorer pain-related and psychosocial outcomes long-term.

CONCLUSIONS

Findings from the current scoping review and proposed conceptual framework will guide future research and treatment efforts for youths experiencing pain and trauma and/or PTSS and thereby enhance long-term outcomes.

Sexual Dysfunction Among Childhood Sexual Abuse Survivors: The "Functional" Dysfunction?

Various studies have established the association between child sexual abuse and sexual dysfunction. Although sexual dysfunction can be a distressing and undesirable condition for survivors of child sexual abuse, the current article suggests viewing sexual dysfunction not solely as a negative outcome but as a condition with a potent psychological function in regulating various psychological and relational needs among survivors. The main question addressed in the current paper is: What are the functional aspects of sexual dysfunction among child sexual abuse survivors? Four main protective purposes for sexual dysfunction among survivors of child sexual abuse are proposed: avoiding re-traumatization, regulating closeness within the relationship, gaining a sense of power and control and avoiding vulnerability, and restoring a positive sense of self. Although healthy sexual functioning is a desirable long-term goal for survivors, therapists need to view sexual dysfunction within the context of trauma, and to understand the protective functions of dysfunctions, before attempting to restore sexual function.

Co-occurrence of severe PTSD, somatic symptoms and dissociation in a large sample of childhood trauma inpatients: a network analysis

Co-occurrence of mental disorders including severe PTSD, somatic symptoms, and dissociation in the aftermath of trauma is common and sometimes associated with poor treatment outcomes. However, the interrelationships between these conditions at symptom level are not well understood. In the present study, we aimed to explore direct connections between PTSD, somatic symptoms, and dissociation to gain a deeper insight into the pathological processes underlying their comorbidity that can inform future treatment plans. In a sample of 655 adult inpatients with a diagnosis of severe PTSD following childhood abuse (85.6% female; mean age = 47.57), we assessed symptoms of PTSD, somatization, and dissociation. We analyzed the comorbidity structure using a partial correlation network with regularization. Mostly positive associations between symptoms characterized the network structure. Muscle or joint pain was among the most central symptoms. Physiological reactivation was central in the full network and together with concentrations problems acted as bridge between symptoms of PTSD and somatic symptoms. Headaches connected somatic symptoms with others and derealization connected dissociative symptoms with others in the network. Exposure to traumatic events has a severe and detrimental effect on mental and physical health and these consequences worsen each other trans-diagnostically on a symptom level. Strong connections between physiological reactivation and pain with other symptoms could inform treatment target prioritization. We recommend a dynamic, modular approach to treatment that should combine evidence-based interventions for PTSD and comorbid conditions which is informed by symptom prominence, readiness to address these symptoms and preference.
