Development of a core outcome set for treatment studies for provoked vestibulodynia.

BACKGROUND: There is an inconsistency in treatment outcomes used in clinical trials for provoked vestibulodynia (PVD), which makes it impossible to compare the effects of different interventions. AIM: In this study, we completed the first step in creating a core outcome set (COS), defining what outcomes should be measured in clinical trials for PVD. METHODS: Identification of outcomes used in studies was done by extracting data from clinical trials in a recently published systematic review and via review of clinical trials for PVD registered on ClinicalTrials.gov. The COS process consisted of 2 rounds of Delphi surveys and a consensus meeting, during which the final COS was decided through a modified nominal group technique. OUTCOMES: Consensus on what outcomes to include in a COS for PVD. RESULTS: Forty scientific articles and 92 study protocols were reviewed for outcomes. Of those, 36 articles and 25 protocols were eligible, resulting in 402 outcomes, which were then categorized into 63 unique outcomes. Participants consisted of patients, relatives/partners of patients, health care professionals, and researchers. Out of 463 who registered for participation, 319 and 213 responded to the first and second surveys, respectively. The consensus meeting consisted of 18 members and resulted in 6 outcomes for the COS to be measured in all treatment trials regardless of intervention: insertional pain (nonsexual), insertional pain (sexual), provoked vulvar pain by pressure/contact, pain-related interference on one's life, pain interference on sexual life, and sexual function. CLINICAL IMPLICATIONS: Critical outcomes to be measured in clinical trials will allow for accurate comparison of outcomes across treatment interventions and provide solid treatment recommendations. STRENGTHS AND LIMITATIONS: The major strengths of the study are the adherence to methodological recommendations and the intentional focus on aspects of diversity of participating stakeholders (eg, status such as patients with lived experience and researchers, inclusiveness with respect to sexual identity), the latter of which will allow for broader application and relevance of the COS. Among the limitations of the study are the low rate of participants outside North America and Europe and the lower response rate (about 50%) for the second Delphi survey. CONCLUSION: In this international project, patients, health care professionals, and researchers have decided what critical outcomes are to be used in future clinical trials for PVD. Before the COS can be fully implemented, there is also a need to decide on how and preferably when the outcomes should be measured.

Interpersonal Experiences with Persistent Genital Arousal: Connections between Symptom Disclosure, Partner Responses, and Catastrophizing on Relationship Adjustment and Symptom Severity.

Increased research attention to interpersonal factors in genitopelvic pain conditions, such as vulvodynia, have led to more comprehensive understanding of couple dynamics in pain, sexual, and relationship outcomes. There has been very little examination of interpersonal factors in Persistent Genital Arousal Disorder/Genitopelvic Dysesthesia (PGAD/GPD), a distressing condition involving persistent sensations of arousal and often pain. The aims of the present study were to examine whether individuals disclose their symptoms to intimate partners and whether interpersonal variables (e.g., partner responses, symptom disclosure, and catastrophizing) are related to relationship adjustment and symptom severity. Seventy-six individuals with symptoms of PGAD/GPD participated in a one-time anonymous online survey. Over three-quarters (85.5%) of the sample disclosed their symptoms to their partners in some way. Greater supportive partner responses and lower symptom catastrophizing were related to better relationship adjustment among participants with PGAD/GPD symptoms. Greater symptom catastrophizing also predicted greater PGAD/GPD symptom severity. Partner responses were not related to PGAD/GPD symptom severity. Although interpersonal factors have been linked to symptom severity in chronic pain and genitopelvic pain conditions, the results of the current study suggest that interpersonal factors may play a slightly different role in PGAD/GPD symptom experiences and in the conceptualization of PGAD/GPD more broadly.

A Prospective, Longitudinal Comparison of Sexual Distress Across Relationship Status During the COVID-19 Pandemic.

Numerous studies have described declines in sexual well-being during the COVID-19 pandemic, although experiences of sexual distress during this time appear to be mixed. Previous research has relied on cross-sectional methodology and focused on individuals in relationships. Furthermore, little is known about the frequency of "COVID-safe" sexual behaviors, such as online sexual activities. These gaps in the literature were addressed using a prospective, longitudinal online study examining sexual distress, predictors of sexual distress (i.e., perceived stress), and online sexual activities over time in single and partnered individuals. Participants were single (N = 64) and partnered (N = 60) individuals who completed surveys at three timepoints over a 6-month period during the COVID-19 pandemic. Mean age across the two groups was 29 years, and approximately half were women (51.6% and 50%, respectively). Results indicated that single individuals reported significantly higher sexual distress than partnered individuals at Times 1 and 2, but not at Time 3. Sexual distress significantly decreased over time for individuals in the single group but remained stable for partnered individuals. At each timepoint, there was a conditional effect of perceived stress on sexual distress depending on one's relationship status, and the nature of these conditional effects changed throughout the course of the study. Results suggested that single individuals demonstrated improvements in sexual distress over time. Perceived stress is an important predictor of sexual distress but may operate differently depending on relationship status. Results highlight the resiliency of both single and partnered individuals during the COVID-19 pandemic.

An Investigation of Associations between Pain Catastrophizing and Pain Disability in a Diverse Sample of Persons with Endometriosis.

OBJECTIVE: This study sought to investigate associations between components of pain catastrophizing (using the Pain Catastrophizing Scale; rumination, magnification, and helplessness) and components of pain disability (using the Pain Disability Index; family/home responsibilities, recreation, social activity, occupation, sexual behaviour, self-care, life-support activity) in a diverse sample of persons with endometriosis. METHODS: A total of 686 persons with a self-reported clinician-identified diagnosis of endometriosis participated in this study. Two-tailed independent samples t tests were used to examine between-group differences in pain disability and pain catastrophizing among those below and above clinically relevant moderate pain intensity levels. Between-group differences in pain disability among those below and above the clinically relevant pain catastrophizing level, and between-group differences in pain catastrophizing among those below and above the clinically relevant moderate pain disability level, were also analyzed. RESULTS: Experiencing moderate or greater levels of pain intensity was associated with increased levels of pain disability and pain catastrophizing (P < 0.001). Strong associations between clinically relevant levels of pain catastrophizing and increased levels of pain disability (P < 0.001), in addition to between clinically relevant levels of moderate pain disability and increased levels of pain catastrophizing (P < 0.001), were found at both the total and subdomain levels. CONCLUSION: Pain catastrophizing significantly affects pain disability and vice versa. Future research should examine the temporal relationship between catastrophizing and disability to inform intervention practices. Health care providers are strongly encouraged to evaluate the effects of endometriosis in patients using a biopsychosocial framework.

The contribution of the cervix to sexual response: an online survey study.

BACKGROUND: The role of the cervix in sexual response has been poorly studied, despite previous research indicating that some women experience pleasurable sexual sensations from cervical stimulation; given previous reports of sexual issues after cervix electrocautery, it is possible that cervical injury may compromise the role of the cervix in sexual functioning. AIM: The aims of this study were to examine locations of pleasurable sexual sensations, to identify sexual communication barriers, and to investigate if cervical procedures are associated with negative impacts on sexual function. METHODS: Women with (n = 72) and without (n = 235) a history of a gynecological procedure completed an online survey assessing demographics, medical history, sexual function (including locations of sexual pleasure and pain on diagrams), and barriers. The procedure group was divided into subgroups of those who had experienced a cervical (n = 47) or noncervical (n = 25) procedure. Chi-square analyses and t tests were conducted. OUTCOMES: Outcomes included locations and ratings of pleasurable and painful sexual stimulation, as well as sexual function. RESULTS: Over 16% of participants reported experiencing some pleasurable sexual sensations from the cervix. The gynecological procedure group (n = 72) reported significantly higher pain in the vagina and lower rates of pleasure in their external genitals, vagina, deep vagina, anterior and posterior vaginal walls, and clitoris vs the non-gynecological procedure (n = 235) group. The gynecological procedure group and the cervical procedure subgroup (n = 47) reported significant decreases in desire, arousal, and lubrication and increased avoidance of sexual activity due to vaginal dryness. The gynecological procedure group reported significant pain with vaginal stimulation, whereas the cervical subgroup identified significant pain with cervical and clitoral stimulation. CLINICAL IMPLICATIONS: Cervical stimulation elicits some pleasurable sexual sensations for many women, and gynecological procedures that affect the cervix are associated with pain and sexual issues; thus, health care providers should counsel patients about the possibility of related sexual concerns. STRENGTHS AND LIMITATIONS: This study is the first to examine locations of pleasure and pain and experiences of sexual pleasure and function in participants who underwent a gynecological procedure. A hybrid measure was used to assess sexual issues, including symptoms of dysfunction. CONCLUSION: Results indicate an association between cervical procedures and sexual issues, supporting the need to inform patients of this possibility following cervical procedures.

"It happens to everyone" vs. "You're not a real man": The relationship between intimate communication and men's sexual difficulties.

Sexual difficulties can have negative intrapersonal and interpersonal consequences on both members of a couple, but little is known about how communication in a relationship relates to men's experience of sexual difficulties. We explored the associations among components of intimate communication, men's sexual difficulties, relationship satisfaction, and sexual satisfaction in a sample of men in mixed-gender and same-gender relationships (n = 341). Among all components of intimate communication, sexual communication was most consistently related to indicators of sexual difficulties, relationship satisfaction, and sexual satisfaction. Results generally remained consistent across mixed-gender and same-gender couples, with some exceptions relevant to sexual difficulties.

Sexual script flexibility after a prostate cancer diagnosis: Implications for sexual satisfaction.

PURPOSE: To investigate the relationship among sexual functioning, sexual script flexibility, and sexual satisfaction in individuals diagnosed with prostate cancer. DESIGN: Cross-sectional online survey. PARTICIPANTS: Sixty-one men diagnosed with localized prostate cancer. METHODS: Online survey of sexual functioning, sexual script flexibility, and sexual satisfaction. Ordinal logistic regression investigated predictors of sexual satisfaction. FINDINGS: Greater sexual script flexibility was associated with a greater likelihood of being sexually satisfied. CONCLUSIONS: Helping patients explore different ways of being sexual after treatment could help with sexual satisfaction maintenance. IMPLICATIONS: Patients' sexual satisfaction may benefit from discussions of issues related to sexuality and ways to work around treatment-related sexual dysfunction with healthcare providers.

Persistent Genital Arousal in Relationships: A Comparison of Relationship, Sexual, and Psychological Well-Being.

BACKGROUND: Persistent Genital Arousal Disorder/Genitopelvic Dysesthesia (PGAD/GPD) is characterized by sensations of physiological genital sexual arousal (and/or other types of genitopelvic dysesthesia) that occur in the absence of subjective feelings of sexual desire. AIMS: The aim of this study was to compare relationship, sexual, and psychological well-being in partnered individuals with and without distressing symptoms of PGAD/GPD. METHODS: The sample (N = 65 individuals with vulvas and vaginas, N = 11 individuals with penises) of 152 partnered individuals (N = 76 with and 76 without PGAD/GPD symptoms) participated in a one-time anonymous online survey. OUTCOMES: The questionnaires assessed relationship satisfaction (Couple Satisfaction Index-Short Form, CSI); sexual satisfaction (Global Measure of Sexual Satisfaction, GMSEX); sexual functioning (Female Sexual Functioning Index, FSFI, or International Index of Erectile Functioning, IIEF); sexual distress (Sexual Distress Scale, SDS); and psychological well-being, as determined by the presence of depression and/or anxiety symptoms (Hospital Anxiety and Depression Scale, HADS). RESULTS: Among individuals with vulvas and vaginas, those with PGAD/GPD symptoms reported significantly lower relationship and sexual satisfaction, greater sexual distress, and more symptoms of depression and anxiety than their counterparts in the control group. In addition, these individuals with PGAD/GPD symptoms also reported significantly worse sexual functioning (arousal, orgasm, satisfaction, and pain), and they were significantly more distressed about each aspect of their sexual functioning difficulties compared to those in the control group. Among the small sample of individuals with penises (N = 11), descriptive analyses revealed that total sexual functioning scores did not differ across the PGAD/GPD symptom and control groups. In addition, 64.5% of the total sample with PGAD/GPD symptoms managed unwanted genital arousal by avoiding sex with their partner, while 55.3% managed their symptoms by having sex with their partner, and some individuals with PGAD/GPD used both strategies. CLINICAL IMPLICATIONS: The finding that PGAD/GPD symptoms impact relationships indicates that treatment for PGAD/GPD should include consideration of the well-being of one's intimate relationship(s). STRENGTHS & LIMITATIONS: This study added to the small literature on experiences of PGAD/GPD in relationships, and it was the first to assess sexual satisfaction. Limitations include the small sample of individuals with penises, and the cross-sectional, correlational design, which does not allow for causal conclusions to be drawn. CONCLUSION: Results emphasize the importance of continued research of this population (and their partners) in order to improve diagnosis, intervention, and recognition within the medical community.

Moderators of the Relationship Between Pain and Pain-Related Sexual Disability in Women with Provoked Vestibulodynia Symptoms.

BACKGROUND: Previous studies have demonstrated the deleterious effects of pain anxiety (ie, the degree to which one fears pain), stress, and solicitous partner responses (ie, expressions of sympathy and attention to one's partner's pain) on pain and pain-related disability, but little is known about whether these variables moderate the robust pain-pain-related disability relationship in individuals with provoked vestibulodynia (PVD). AIM: We investigated whether pain anxiety, stress, and solicitous partner responses moderated the relationship between penetrative pain and pain-related sexual disability in women with PVD symptoms. METHODS: Participants with PVD symptoms (N = 65, age range = 18-73 years) completed an online survey assessing pain anxiety (Pain Anxiety Symptoms Scale-20), perceived stress (Perceived Stress Scale), solicitous partner responses (WHYMPI Solicitous Responses Scale), penetrative pain (Female Sexual Function Index), and pain-related sexual disability (Pain Disability Index). Moderated regression analyses were performed using pain anxiety, stress, and solicitous partner responses as moderators of the relationship between penetrative pain, and pain-related sexual disability. OUTCOMES: Outcomes in the current study included the moderating effect of pain anxiety, perceived stress, and solicitous partner responses on the relationship between penetrative genital pain and pain-related disability in sexual behavior. RESULTS: Higher genital pain from penetrative intercourse and higher pain anxiety significantly predicted higher pain-related sexual disability, but perceived stress was not significantly related to sexual disability. Solicitous partner responses were significantly positively correlated with pain-related sexual disability. None of the moderators significantly moderated the pain-pain-related sexual disability relationship. CLINICAL IMPLICATIONS: For women with PVD, pain anxiety and solicitous partner responses to their pain may exacerbate their pain-related sexual disability, signifying that pain anxiety and solicitous partner responses represent important targets of therapeutic intervention for women with PVD. STRENGTHS AND LIMITATIONS: The present study extended past research on the relationships between psychological and behavioral factors and pain in women with PVD symptoms by demonstrating the deleterious relationship between pain anxiety, solicitous responses, and pain-related sexual disability. However, the study was correlational in nature, which precludes conclusions about the effect of pain anxiety, and solicitous partner responses on pain-related sexual disability. CONCLUSION: High pain anxiety and frequent solicitous partner responses to an individual's pain predicted higher pain-related sexual disability, suggesting that it may be possible to improve the quality of life of PVD sufferers through interventions that aim to decrease pain anxiety, and solicitous partner responses, in addition to interventions that aim to decrease pain per se.

Comparing Self-Reported Pain During Intercourse and Pain During a Standardized Gynecological Exam at 12- and 24-Month Postpartum.

BACKGROUND: There is limited information about the physical indicators and biopsychosocial predictors of self-reported pain during intercourse and pain during a gynecological examination at 12- and 24-month following childbirth. AIM: This longitudinal study aimed to (i) Compare the findings from gynecological exams at 12- and 24-month postpartum for women with minimal vs clinically significant pain during intercourse; (ii) Assess the biomedical and psychosocial correlates of self-reported pain during intercourse and the vestibular pain index (VPI) from the cotton-swab test at 12- and 24-month postpartum; (iii) Establish the relationship between self-reported pain during intercourse and the cotton-swab test. METHODS: Women (N = 97 at 12 months postpartum and N = 44 at 24-month postpartum) recruited from a local women's hospital completed online surveys in their first trimester of pregnancy and at 12- and 24-month postpartum to assess pain during intercourse and biopsychosocial variables. Those with clinically significant (pain ≥4/10 on a visual analogue scale) were matched with those reporting minimal pain (pain <3/10) and underwent a gynecological exam including a cotton-swab test. Descriptive analyses, multiple regressions, and bivariate correlations were conducted to address each of the study aims, respectively. MAIN OUTCOME MEASURES: (i) Findings from the gynecological examination (ii) Numerical rating scale for the VPI; (iii) Visual analogue scale of pain during intercourse. RESULTS: The majority of women in both pain groups had normal physical findings in the gynecological exam. Greater sexual distress and pain catastrophizing at 12- and 24-month postpartum were significantly associated with greater pain during intercourse at each time-point, respectively. Greater pain catastrophizing at 12 months postpartum was significantly associated with greater pain during the cotton-swab test at that time-point. Lower relationship satisfaction at 12 months postpartum was associated with greater VPI ratings at 24 months postpartum. Pain during intercourse and the VPI were moderately and positively correlated. CLINICAL IMPLICATIONS: Addressing psychosocial variables may interrupt the maintenance of postpartum pain. Following an initial assessment, self-reported pain intensity may be a suitable proxy for repeated examinations. STRENGTHS & LIMITATIONS: This study is the first to describe the physical findings and psychosocial predictors of pain during intercourse and the VPI at 12- and 24-month postpartum. The homogenous and small sample may limit generalizability. CONCLUSION: There were no observable physical indicators of clinically significant postpartum pain during intercourse. Psychosocial variables were linked to women's greater postpartum pain during intercourse and VPI ratings. Rossi MA, Vermeir E, Brooks M, et al.

Investigation of the Relationships among Self-Efficacy, Stress, and Dyspareunia during the COVID-19 Pandemic.

This study examined whether low self-efficacy and heightened perceived stress were associated with dyspareunia at two timepoints during COVID-19. Sixty-two participants (31 with and 31 without dyspareunia) completed a longitudinal online survey. Self-efficacy declined during the pandemic, and individuals with dyspareunia reported lower self-efficacy compared to those without dyspareunia. Although stress was greater for those with dyspareunia, both groups reported stress reductions over time. Lower stress was associated with increases in self-efficacy. This study is the first to examine longitudinal trends of dyspareunia during the COVID-19 pandemic and illuminates psychological factors that may influence the experience of dyspareunia.

An Investigation of Sexual and Relationship Adjustment During COVID-19.

The COVID-19 pandemic and the mitigation measures put in place have resulted in universal disruption in the usual ways of life for individuals. The current study sought to investigate how aspects of sexual health (well-being and functioning) and relationship satisfaction changed or remained stable during the pandemic. During two separate time points (Time 1 including Time 1 and a retrospective baseline, Time 2), participants completed online measures of sexual well-being (sexual pleasure, partnered and solitary orgasm frequency, sexual distress), sexual functioning, and relationship satisfaction. Participants reported slight declines in sexual pleasure, frequency of orgasms with a partner, and frequency of solitary orgasms from pre-COVID-19 (retrospective baseline) to Time 1, with no significant differences in sexual distress and relationship satisfaction. For individuals with vulvas, sexual functioning improved from Time 1 to Time 2, whereas no significant differences in sexual functioning were observed for individuals with penises. Aspects of sexual health and relational satisfaction did not sufficiently change across time points to be considered meaningful health outcome changes. Given that minimal disruptions were noted in pre-COVID-19 to COVID-19 sexuality, these results highlight the potential resiliency of individuals' sexuality when facing sudden changes in their daily lives. Implications of COVID-19's effects on sexual well-being and relationship satisfaction research are broadly discussed.

International Society for the Study of Women's Sexual Health (ISSWSH) Review of Epidemiology and Pathophysiology, and a Consensus Nomenclature and Process of Care for the Management of Persistent Genital Arousal Disorder/Genito-Pelvic Dysesthesia (PGAD/GPD).

BACKGROUND: Persistent genital arousal disorder (PGAD), a condition of unwanted, unremitting sensations of genital arousal, is associated with a significant, negative psychosocial impact that may include emotional lability, catastrophization, and suicidal ideation. Despite being first reported in 2001, PGAD remains poorly understood. AIM: To characterize this complex condition more accurately, review the epidemiology and pathophysiology, and provide new nomenclature and guidance for evidence-based management. METHODS: A panel of experts reviewed pertinent literature, discussed research and clinical experience, and used a modified Delphi method to reach consensus concerning nomenclature, etiology, and associated factors. Levels of evidence and grades of recommendation were assigned for diagnosis and treatment. OUTCOMES: The nomenclature of PGAD was broadened to include genito-pelvic dysesthesia (GPD), and a new biopsychosocial diagnostic and treatment algorithm for PGAD/GPD was developed. RESULTS: The panel recognized that the term PGAD does not fully characterize the constellation of GPD symptoms experienced by patients. Therefore, the more inclusive term PGAD/GPD was adopted, which maintains the primacy of the distressing arousal symptoms and acknowledges associated bothersome GPD. While there are diverse biopsychosocial contributors, there is a common underlying neurologic basis attributable to spontaneous intense activity of the genito-pelvic region represented in the somatosensory cortex and its projections. A process of care diagnostic and treatment strategy was developed to guide the clinician, whenever possible, by localizing the symptoms as originating in any of five regions: (i) end organ, (ii) pelvis/perineum, (iii) cauda equina, (iv) spinal cord, and (v) brain. Psychological treatment strategies were considered critical and should be performed in conjunction with medical strategies. Pharmaceutical interventions may be used based on their site and mechanism of action to reduce patients' symptoms and the associated bother and distress. CLINICAL IMPLICATIONS: The process of care for PGAD/GPD uses a personalized, biopsychosocial approach for diagnosis and treatment. STRENGTHS AND LIMITATIONS: Strengths and Limitations: Strengths include characterization of the condition by consensus, analysis, and recommendation of a new nomenclature and a rational basis for diagnosis and treatment. Future investigations into etiology and treatment outcomes are recommended. The main limitations are the dearth of knowledge concerning this condition and that the current literature consists primarily of case reports and expert opinion. CONCLUSION: We provide, for the first time, an expert consensus review of the epidemiology and pathophysiology and the development of a new nomenclature and rational algorithm for management of this extremely distressing sexual health condition that may be more prevalent than previously recognized.

Prevalence of Persistent Genital Arousal Disorder in 2 North American Samples.

BACKGROUND: Persistent genital arousal disorder (PGAD) is a highly distressing, understudied condition characterized by persistent genital arousal (eg, genital sensations, sensitivity) in the absence of sexual desire. Currently, there is limited information about the prevalence of PGAD based on its proposed diagnostic criteria ("PGAD criteria"). AIM: This study sought to assess the prevalence of PGAD criteria in 2 North American samples: a large, non-clinical sample of Canadian undergraduate students (Study 1), and a nationally representative sample from the U.S. (Study 2). METHODS: The incoming class of undergraduate students (N = 1,634) enrolled in the Introduction to Psychology course at a Canadian university and a nationally representative sample of U.S. participants (N = 1,026) responded to questions about each PGAD criterion, and distress associated with these experiences. OUTCOMES: 5 self-report questions were developed based on each of the Leiblum and Nathan 2001 PGAD criteria, and a measure of associated distress was included. The U.S. sample (Study 2) also responded to questions about medical comorbidities and their knowledge of the term "PGAD." RESULTS: 1.1% (n = 4; Study 1) to 4.3% (n = 22; Study 2) of men and 0.6% (n = 7; Study 1) to 2.7% (n = 14; Study 2) of women reported experiencing all 5 PGAD criteria at a moderate to high frequency. Even greater proportions of participants reported experiencing all 5 criteria at any frequency (6.8-18.8%). Although ratings of associated distress varied, participants who were distressed by these symptoms most frequently endorsed the first PGAD criterion: physiological genital arousal in the absence of sexual excitement or desire. These results are similar to previously reported rates of PGAD. CLINICAL IMPLICATIONS: A non-trivial number of individuals may experience PGAD, and it should be screened for by healthcare practitioners. STRENGTHS & LIMITATIONS: This study is the first to use 2 large, non-clinical samples to assess the prevalence of PGAD symptoms. However, barriers to reporting symptoms, such as shame or embarrassment, may have resulted in underestimates of prevalence in the present sample. CONCLUSION: The prevalence of the 5 PGAD criteria in 2 large non-clinical samples ranged from similar to higher than rates reported in previous research. However, distress ratings associated with each of the 5 criteria varied, with most respondents describing them primarily as neutral or non-distressing. Jackowich RA, Pukall CF.

Recommendations for the Study of Vulvar Pain in Women, Part 1: Review of Assessment Tools.

INTRODUCTION: The etiology and consequences of chronic vulvar pain are multidimensional, resulting in highly variable clinical presentations and no established treatment algorithm. Inconsistent use of measurement tools across studies is a significant barrier to drawing conclusions regarding etiology and treatment. In a companion paper, we review additional methodological challenges to the study of chronic vulvar pain and potential solutions. AIM: To review and recommend assessment and measurement tools for vulvar pain and associated key outcomes. METHODS: The authors reviewed the scientific evidence related to measurement of vulvar pain and made decisions regarding recommendations via discussion and consensus. MAIN OUTCOME MEASURE: We assessed measurement tools for vulvar pain and related outcomes and considered advantages and disadvantages of their use. RESULTS: Empirically validated measurement tools are available and should be used uniformly across studies to support comparisons and pooling of results. There is, at times, a trade-off between advantages and disadvantages when selecting a particular tool, and researchers should be guided by their specific research aims, feasibility, and potential to gain further knowledge in the field. Researchers should incorporate a biopsychosocial assessment of vulvar pain and its consequences. CLINICAL IMPLICATIONS: This review provides a comprehensive list of measurement tool recommendations for use in clinical research, and in some cases, clinical practice. STRENGTHS & LIMITATIONS: This expert review can guide study design and decision-making for those researching vulvar pain and its consequences. The review content and recommendations are based on expert knowledge of the literature rather than a formal systematic review. CONCLUSION: A thorough consideration of vulvar pain assessment tools is essential for continued progress toward identifying factors involved in the development and maintenance of vulvar pain and developing empirically supported treatments.

A Comparison of Medical Comorbidities, Psychosocial, and Sexual Well-being in an Online Cross-Sectional Sample of Women Experiencing Persistent Genital Arousal Symptoms and a Control Group.

BACKGROUND: Persistent genital arousal disorder (PGAD) is characterized by symptoms of distressing physiological sexual arousal (Persistent genital arousal [PGA] symptoms such as genital vasocongestion, sensitivity, or both) that occur in the absence of sexual desire. There continues to be a lack of systematic research on this condition. Little is known about the common medical comorbidities and psychological, sexual, or relationship well-being of individuals who experience PGA symptoms. AIMS: To compare these biopsychosocial factors in an age-matched sample of women with and without symptoms of PGA. A secondary aim was to examine what symptom factors (associated distress, symptom severity) and cognitive factors (eg, catastrophizing of vulvar sensations) were associated with psychosocial outcomes in women with symptoms of PGA. METHODS: Age-matched samples of women with (n = 72) and without (n = 72) symptoms of PGA completed a comprehensive online survey. MAIN OUTCOME MEASURES: Participants self-reported their medical histories and completed validated measures of psychosocial functioning (depressive and anxiety symptoms, catastrophizing of vulvar sensations, sexual functioning and distress, and relationship functioning). RESULTS: Women with symptoms of PGAD reported significantly greater depressive and anxiety symptoms, sexual distress, and suicidal ideation, as well as significantly poorer relationship functioning than women without PGA symptoms. Catastrophizing of vulvar sensations was related to PGA symptom ratings (greater severity, distress) and psychosocial outcomes (greater depression, anxiety, and sexual distress). CLINICAL IMPLICATIONS: The results of this study highlight medical and psychosocial difficulties associated with PGA symptoms, which should be assessed and addressed as essential components of treatment. STRENGTHS & LIMITATIONS: This study seeks to address the paucity of research on the well-being of women with PGA symptoms by undertaking a comparison of age-matched samples using validated questionnaires. This study is limited by its self-report, cross-sectional design. CONCLUSION: PGA symptoms are associated with significant health and psychological difficulties. These results highlight the need for continued research in this area to improve identification and treatment for this population. Jackowich RA, Poirier É, Pukall CF.

Recommendations for the Study of Vulvar Pain in Women, Part 2: Methodological Challenges.

INTRODUCTION: Chronic vulvar pain is a multidimensional condition with great variability in clinical presentation among affected women. In a companion article, part 1, we reviewed and recommended assessment and measurement tools for vulvar pain and related outcomes with a view toward improving consistency and comparison across studies. Yet methodological challenges to conducting research with this population remain and can further hinder conclusions regarding etiology and treatment. AIM: To discuss methodological challenges to conducting vulvar pain research alongside recommended solutions. METHODS: The expert authors reviewed the scientific evidence related to the study of vulvar pain and made decisions regarding methodological challenges and mitigation strategies via discussion and consensus. MAIN OUTCOME MEASURE: We articulated key challenges to conducting research in this area and formulated recommendations for mitigating these challenges. RESULTS: Challenges to the field include selection and sample biases, heterogeneity of the condition, inclusion of the partner, and neglect of the multidimensional aspects of vulvar pain. 2 key recommendations are more careful and detailed tracking and characterization of research samples and greater multidisciplinary collaboration to better capture the complexity of chronic vulvar pain. CLINICAL IMPLICATIONS: This methodological critique points to several challenges to clinical research with populations struggling with chronic vulvar pain and makes suggestions for how to mitigate these issues. STRENGTH & LIMITATIONS: Comments in this expert review raise awareness regarding core challenges to the study of vulvar pain and can inform study design of clinical research with this population. The content of this review is based on expert knowledge and opinion rather than a formal systematic review or extended consultation process. CONCLUSION: A careful reflection upon methodological challenges facing clinical research of vulvar pain and ways to mitigate such challenges is crucial for improving the quality, generalizability, and uptake of research findings.

Is Mode of Delivery Associated With Sexual Response? A Pilot Study of Genital and Subjective Sexual Arousal in Primiparous Women With Vaginal or Cesarean Section Births.

INTRODUCTION: Although postpartum sexual concerns are common, limited data exist on postpartum sexual response. Furthermore, the physiological process of vaginal birth may negatively impact genital response compared with unlabored cesarean section (C-section), but this hypothesis has yet to be tested. AIM: To (i) compare genital and subjective sexual response and sexual concordance by mode of delivery with inclusion of a control group, (ii) compare groups on self-reported sexual function over the past month, (iii) examine the relationship between laboratory measurement of sexual response and self-reported sexual function, and (iv) investigate association between obstetrical factors and breastfeeding and between sexual response and self-reported sexual function. METHODS: 3 groups of cisgender women were recruited from the community: primiparous women who delivered via vaginal birth within the past 2 years (VB group; n = 16), primiparous women who delivered via unlabored C-section within the past 2 years (CS group, n = 15), and age-matched nulliparous women (NP group, n = 18). Laser Doppler imaging was used to assess genital response while participants watched a neutral and erotic film. MAIN OUTCOME MEASURES: The main outcome measures were change in flux units from neural to erotic video as a measure of genital response, subjective sexual arousal rated continuously throughout films, perceived genital response rated after films, and Female Sexual Function Index (FSFI). RESULTS: Women in the VB group had significantly lower change in flux units than women in the CS (P = .005, d = 1.39) and NP (P < .001, d = 1.80) groups. Groups did not differ on their subjective indices of sexual response or in sexual concordance. Women in both postpartum groups reported lower FSFI scores than women in the NP group. No relationship was determined between FSFI scores and sexual response in the laboratory. Results suggested that genital trauma and breastfeeding may negatively impact FSFI scores, but they were not related to genital response or subjective sexual arousal as measured in the laboratory. CLINICAL IMPLICATIONS: Results underscore the importance of balancing objective and subjective indices of sexual response and function, especially considering the biopsychosocial nature of postpartum sexuality. STRENGTHS & LIMITATIONS: The present study is the first to apply modern sexual psychophysiological methodology to the study of postpartum sexuality. Cross-sectional methodology limits the ability to make causal inferences, and the strict inclusion criteria limits generalizability. CONCLUSION: Physiological changes as a result of labor and delivery may have a detrimental impact on genital response; however, these physiological differences may not impact women's subjective experience of postpartum sexuality.

Effects of Individual Difference Variables, Gender, and Exclusivity of Sexual Attraction on Volunteer Bias in Sexuality Research.

Sexuality research is often regarded as more intrusive than other types of research, contributing to sample self-selection biases. Researchers have consistently found that volunteers and non-volunteers for sexuality studies differ on a number of sexuality-related variables. Despite a large number of studies examining volunteer biases, relatively few have examined the effects of gender and exclusivity of sexual attraction on willingness to volunteer. Given that comparisons on the basis of gender and/or sexual attraction are frequently made in sexuality studies, understanding how these factors may contribute to volunteer bias is particularly important. In the current study, we investigated the impact of gender and sexual attraction, as well as individual difference variables, on hypothetical willingness to volunteer for a variety of sexuality studies, including new measurement technologies not previously investigated. Greater proportions of men and individuals with any degree of same-gender attraction reported that they were willing to volunteer for eye tracking and psychophysiology studies, whereas there were no significant effects of gender or sexual attraction on willingness to volunteer for sexuality surveys. The proportions of volunteers willing to participate were inversely related to study invasiveness. Greater sexual experience and more positive sexual attitudes were significant predictors of willingness to volunteer, whereas gender, sexual attraction, and other sexuality characteristics were not significant predictors. Implications of volunteer bias for research findings are discussed. Strategies to minimize volunteer bias and to examine whether or not recruited samples differ from the population are provided.
