Changes in Autonomic Nervous System Activity are Associated with Changes in Sexual Function in Women with a History of Childhood Sexual Abuse

Diurnal variation of cardiac autonomic activity in adolescent non-suicidal self-injury

Heart rate (HR) and vagally mediated heart rate variability (HRV) are two distinct biomarkers of cardiac autonomic activity. Decreased cardiac vagal activity (or decreased HRV) in particular has been linked with impairments in the functional flexibility of the central autonomic network (CAN), resulting in impaired stress and emotion regulatory capacities. Decreased HRV is widely used as trait marker of psychopathology. Repetitive engagement in non-suicidal self-injury (NSSI) in adolescence correlates with both deficits in stress and emotion regulation, as well as decreased HRV. Existing research has, however, focused on short-term recordings of HR and HRV under resting and phasic conditions. In this study, we examined whether diurnal variation of cardiac autonomic activity, indexed by cosinor parameters of HR and HRV derived from 48 h of ambulatory ECG recording under natural conditions over a weekend, are altered in female adolescents with NSSI disorder compared to controls (HC; N = 30 per study group). Several important confounds, including physical activity, were controlled for. Female adolescents with NSSI show higher rhythm-adjusted 24 h mean levels and greater respective amplitude of HR, as well as lower rhythm-adjusted 24 h mean levels and smaller respective amplitude of HRV. Peak levels in both HR and HRV in the NSSI group were reached approximately 1 h later compared to HC. Severity of exposure to early life maltreatment might be linked with altered amplitudes of 24 h HR and HRV. Diurnal rhythms of cardiac autonomic activity might hold promise as objective indicators of disordered stress and emotion regulation in developmental psychopathology, and as such should be investigated in future studies with rigorous assessment and control of potential confounds.

Anxiety and Depression Symptoms among Youth Survivors of Childhood Sexual Abuse: A Network Analysis

BACKGROUND

Previous studies have frequently reported a high prevalence of co-occurring anxiety and depression among people who experienced stressful events in childhood. However, few have noted the symptomatic relationship of this comorbidity among childhood sexual abuse (CSA) survivors. Therefore, this study's objectives were as follows: (1) to examine the relationship across symptoms between anxiety and depression among CSA survivors; (2) to compare differences between male and female network structures among CSA survivors.

METHODS

A total of 63 Universities and Colleges in Jilin Province, China, covered 96,218 participants in this study, a sub-set data of which met the criteria of CSA was analyzed with the network analysis. The Childhood Trauma Questionnaire-Short Form (CTQ-SF), measured CSA. Anxiety was measured by the seven-item Generalized Anxiety Disorder Scale (GAD-7), and depression was measured by the Patient Health Questionnaire (PHQ-9). The sex difference between anxiety and depression among CSA survivors was compared.

RESULTS

3,479 college students reported the experience of CSA (CTQ-SF total scores ≥ 8), with a prevalence of 3.62% (95% CI: 3.50-3.73%). Among CSA survivors, control worry, sad mood, and energy were central and bridge symptoms of the anxiety and depression network. Meanwhile, male CSA survivors appeared to have a stronger correlation between guilt and suicide, but female CSA survivors seemed to have a stronger correlation between control worry and suicide. Moreover, the edge of control worry-relax-afraid was stronger in the male network, while the edge of restless-relax was stronger in the female network.

CONCLUSION

Control worry, sad mood, and energy are crucial to offer targeted treatment and to relieve anxiety and depression symptoms for CSA survivors. Guilt needs more attention for male CSA survivors, while control worry remains more important for female CSA survivors to reduce suicidal ideation and suicide attempts.

A First Look at Childhood Abuse in Women with Obstructive Sleep Apnea

Study objectives. Women who experienced childhood sexual abuse have higher rates of obesity, a risk factor for obstructive sleep apnea (OSA). We assessed if prior childhood sexual abuse was more common in women with OSA vs. control, with possible mediation by obesity. Methods . We studied 21 women with OSA (age mean±s.d. 59±12 years, body mass index (BMI) 33±8 kg/m 2 , respiratory event index [REI] 25±16 events/hour, Epworth Sleepiness Scale [ESS] 8±5) and 21 women without OSA (age 53±9 years, BMI 25±5 kg/m 2 , REI (in 7/21 women) 1±1 events/hour, ESS 5±3). We evaluated four categories of trauma (general trauma, physical, emotional, and sexual abuse) with the early trauma inventory self-report-short form (ETISR-SF). We assessed group differences in trauma scores with independent samples t-tests and multiple regressions. Parametric Sobel tests were used to model BMI as a mediator for individual trauma scores predicting OSA in women. Results. Early childhood sexual abuse reported on the ETISR-SF was 2.4 times more common in women with vs. without OSA ( p =0.02 for group difference). Other trauma scores were not significantly different between women with and without OSA. However, BMI was a significant mediator ( p =0.02) in predicting OSA in women who experienced childhood physical abuse. Conclusions. Childhood sexual abuse was more common in a group of women with OSA than those without OSA. Additionally, BMI was a mediator for OSA of childhood physical but not sexual abuse. There may be physiological impacts of childhood trauma in women that predispose them to OSA.

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.

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.

The Impact of Child Sexual Abuse on Men's Sexual Function: A Systematic Review

Child sexual abuse (CSA) is strongly associated with sexual dysfunction. However, research about male survivors' sexual functioning after CSA is lacking. The current systematic review searched for all studies that reported on CSA and sexual function among male survivors to answer the following questions: Do male survivors of CSA experience sexual dysfunctions, and if so, to what extent? Does CSA increase the risk of developing sexual dysfunctions in adulthood among men? Studies were identified by searching seven databases and sources of gray literature. The selection criteria included empirical studies involving a population of adult men who experienced CSA before the age of 18. Studies focused on sexual functioning and sexual development after the abuse. Twelve studies met the selection criteria. While some studies confirmed that CSA is a risk factor for sexual dysfunction in adult male survivors, including low sexual drive, problems with arousal, and difficulties with orgasm and pain, other studies failed to find a correlation between sexual dysfunction and CSA. The wide range in quality, methodology, and definitions of CSA and sexual function presented challenges to consistent analysis of the studies and to determine the impact of CSA. Further research is required to fully understand the effect of CSA on adult men's sexual function.

Reduced Heart Rate Variability in Patients With Medically Unexplained Physical Symptoms: A Meta-Analysis of HF-HRV and RMSSD

OBJECTIVE

Medically unexplained physical symptoms (MUPS) and related syndromes are common and place a substantial burden on both patients and society. Chronic psychological distress and dysregulation of the autonomic nervous system may be common factors associated with MUPS, although previous studies have reported mixed results. The aims of this meta-analysis are to provide an updated synthesis of studies investigating heart rate variability (HRV) indices associated with autonomic nervous system functioning in three common MUPS syndromes and to explain inconsistencies in previous study findings.

METHODS

Literature search yielded 58 studies comparing HRV indices of reduced parasympathetic activity of healthy individuals with those of patients with chronic fatigue syndrome (npatients = 271), irritable bowel syndrome (npatients = 1005), and fibromyalgia (npatients = 534). Separate random-effects meta-analyses were conducted on studies measuring root mean square of successive differences (RMSSD) and high-frequency HRV (HF-HRV).

RESULTS

Regardless of syndrome type, patients had significantly lower RMSSD (k = 22, Hedges g = -0.37 [-0.53 to -0.21], p < .001) and HF-HRV (k = 52, Hedges g = -0.69 [-1.03 to -0.36], p < .001) than did healthy individuals. Sample age and publication year explained a substantial variation in RMSSD, whereas controlling for confounders in statistical analyses explained variation in HF-HRV.

CONCLUSIONS

Lower RMSSD and HF-HRV in patients with MUPS versus healthy controls indicates that autonomic nervous system dysregulation, particularly lower parasympathetic activity, may play a role in patients with these conditions. This conclusion may have important implications for the underlying mechanisms and treatment of MUPS and related syndromes.

Addressing Sexual Dysfunction After Childhood Sexual Abuse: A Clinical Approach from an Attachment Perspective

Sexual dysfunctions are very prevalent among survivors of childhood sexual abuse. While the relationship between sexual abuse and sexual dysfunction is well-established, understanding of the mechanisms explaining this relationship is still limited and has not been studied thoroughly. The current article presents a preliminary, theoretical model of the association between childhood sexual abuse, and sexual dysfunctions in adulthood from an attachment-trauma perspective. This model is based on previous literature and hours of clinical work in sex therapy and attachment theory-based therapy, and identifies important factors that have not been adequately accounted for in the literature.

Reading the Child Within: How Bibliotherapy Can Help the Victim of Child Sexual Abuse

Bibliotherapy, the use of storytelling as part of the healing process, has been successfully incorporated into clinical practice for a variety of indications including psychological trauma. This therapeutic modality, which incorporates mindful meditation, non-threatening use of metaphor, and autonomic regulation, can help children and adults alike, who are willing to engage in a story. Yet, bibliotherapy has not been widely adapted as a routine part of the therapeutic toolbox in the context of sufferers of childhood sexual abuse. Here, we review current practices regarding the adjunctive use of bibliotherapy for victims of child sexual abuse, touch upon the theoretical basis of bibliotherapy, and lay out a number of readily-useable strategies for implementing bibliotherapy in one's practice.

Could affect regulation via vagal nerve self- stimulation be a maintaining factor in non-suicidal self-harm?

BACKGROUND

Non-suicidal self-injury (NSSI) is a serious and common phenomenon which has been linked with emotion or affect regulation. The capacity for top-down emotion regulation has also been linked to vagal tone. Vagal tone is known to be low in groups with a propensity to engage in NSSI.

HYPOTHESIS

Some forms of NSSI, both direct and indirect, may result in vagal stimulation. The resulting increase in vagal tone may be linked to activation of prefrontal areas and improved top-down emotion regulation. This may be a maintaining factor in NSSI.

EVALUATION

Cutting with the sight of blood, the use of ligatures, eating disorders and risky sexual behaviour, behaviours that could be considered direct or indirect forms of NSSI, are all plausible methods of vagal self-stimulation.

CONCLUSION

NSSI may increase vagal tone. This may result in improved top down emotion regulation and result in a calmer emotional state. These vagal effects may be important maintaining factors in self-harm. This has important implications for the study and possible management of a common and serious issue.

A Rapid Review of Sexual Wellbeing Definitions and Measures: Should We Now Include Sexual Wellbeing Freedom?

An increasing number of studies refer to sexual wellbeing and/or seek to measure it, and the term appears across various policy documents, including sexual health frameworks in the UK. We conducted a rapid review to determine how sexual wellbeing has been defined, qualitatively explored and quantitatively measured. Eligible studies selected for inclusion from OVID Medline, PsychInfo, PubMed, Embase, CINAHL were: in English language, published after 2007, were peer-reviewed full articles, focused on sexual wellbeing (or proxies for, e.g. satisfaction, function), and quantitatively or qualitatively assessed sexual wellbeing. We included studies with participants aged 16-65. Given study heterogeneity, our synthesis and findings are reported using a narrative approach. We identified 162 papers, of which 10 offered a definition of sexual wellbeing. Drawing upon a socio-ecological model, we categorised the 59 dimensions we identified from studies under three main domains: cognitive-affect (31 dimensions); inter-personal (22 dimensions); and socio-cultural (6 dimensions). Only 11 papers were categorised under the socio-cultural domain, commonly focusing on gender inequalities or stigma. We discuss the importance of conceptualising sexual wellbeing as individually experienced but socially and structurally influenced, including assessing sexual wellbeing freedom: a person's freedom to achieve sexual wellbeing, or their real opportunities and liberties.

A Place for Sexual Dysfunctions in an Empirical Taxonomy of Psychopathology

Sexual dysfunctions commonly co-occur with various depressive and anxiety disorders. An emerging framework for understanding the classification of mental disorders suggests that such comorbidity is a manifestation of underlying dimensions of psychopathology (or "spectra"). In this review, we synthesize the evidence that sexual dysfunctions should be included in the empirical taxonomy of psychopathology as part of the internalizing spectrum, which accounts for comorbidity among the depressive and anxiety disorders. The review has four parts. Part 1 summarizes the empirical basis and utility of the empirical taxonomy of psychopathology. Part 2 reviews the prima facie evidence for the hypothesis that sexual dysfunctions are part of the internalizing spectrum (i.e., high rates of comorbidity; shared cognitive, affective, and temperament characteristics; common neural substrates and biomarkers; shared course and treatment response; and the lack of causal relationships between them). Part 3 critically analyzes and integrates the results of the eight studies that have addressed this hypothesis. Finally, Part 4 examines the implications of reconceptualizing sexual dysfunctions as part of the internalizing spectrum, and explores avenues for future research.
