The Sensitivity to Pain Traumatization Scale-Child Version (SPTS-C): Development and preliminary validation.

Background: Sensitivity to pain traumatization is defined as the propensity to develop cognitive, affective, and behavioral responses to pain that resemble a traumatic stress reaction. To date, sensitivity to pain traumatization has been assessed in adults (Sensitivity to Pain Traumatization Scale [SPTS-12]) and parents of youth with chronic pain (Sensitivity to Pain Traumatization Scale-Parent version [SPTS-P]). SPT may be relevant in the context of pediatric chronic pain given the substantial comorbidity between posttraumatic stress symptoms and pain. Aims: This prospective study aimed to adapt the SPTS-12 for use in youth and to evaluate the psychometric properties of the new scale. Methods: Participants included 175 youth with chronic pain (Mage = 14.31 years, 73% girls) referred to outpatient chronic pain programs. At baseline, youth self-reported the levels of their sensitivity to pain traumatization (Sensitivity to Pain Traumatization Scale-Child version [SPTS-C]), as well as their pain symptoms, pain-related anxiety, posttraumatic stress symptoms, and attentional control. Three months later, youth self-reported their pain symptoms and completed the SPTS-C. Results: The SPTS-C had a one-factor structure that explained 48% of variance and demonstrated good reliability and construct validity. SPTS-C baseline scores predicted follow-up levels of pain interference but not pain intensity or pain unpleasantness. Conclusions: The results provide preliminary evidence for the psychometric properties of the SPTS-C and the potential role of SPT in pediatric chronic pain outcomes.

Contexte: La sensibilité à la traumatisation de la douleur est définie comme la propension à développer des réponses cognitives, affectives et comportementales à la douleur qui ressemblent à une réaction de stress traumatique. À ce jour, la sensibilité à la traumatisation de la douleur a été évaluée chez les adultes (Échelle de sensibilité à la traumatisation de la douleur [SPTS-12]) et chez les parents de jeunes souffrant de douleur chronique (Échelle de sensibilité à la traumatisation de la douleur - Version parent [SPTS-P]). La sensibilité à la traumatisation de la douleur peut être pertinente dans le contexte de la douleur chronique pédiatrique étant donné la comorbidité importante entre les symptômes de stress post-traumatique et la douleur.Objectifs: Cette étude prospective visait à adapter le SPTS-12 pour une utilisation chez les jeunes et à évaluer les propriétés psychométriques de la nouvelle échelle.Méthodes: Les participants comprenaient 175 jeunes souffrant de douleur chronique (âge M = 14,31 ans, 73 % de filles) référés aux programmes de traitement ambulatoire de la douleur chronique. Au départ, les jeunes ont autodéclaré les niveaux de leur sensibilité à la traumatisation de la douleur (Échelle de sensibilité à la traumatisation de la douleur - version enfant [SPTS-C]), ainsi que leurs symptômes de douleur, leur anxiété liée à la douleur, leurs symptômes de stress post-traumatique et leur contrôle attentionnel. Trois mois plus tard, les jeunes ont autodéclaré leurs symptômes de douleur et ont répondu au SPTS-C.Résultats: Le SPTS-C avait une structure à un facteur qui expliquait 48 % de la variance et démontrait une bonne fiabilité ainsi qu'une bonne validité de la construction. Les scores obtenus au SPTS-C au départ prédisaient les niveaux d'interférence de la douleur au suivi mais pas l'intensité de la douleur ou le désagrément de la douleur.Conclusions: Les résultats présentent des preuves préliminaires des propriétés psychométriques du SPTSC et le rôle potentiel de la sensibilité à la traumatisation de la douleur dans les résultats liés à la douleur chronique pédiatrique.

Sensitivity to Pain Traumatization and Its Relationship to the Anxiety-Pain Connection in Youth with Chronic Pain: Implications for Treatment.

The bidirectional relationship between anxiety and chronic pain in youth is well-known, but how anxiety contributes to the maintenance of pediatric chronic pain needs to be elucidated. Sensitivity to pain traumatization (SPT), an individual's propensity to develop responses to pain that resemble a traumatic stress response, may contribute to the mutual maintenance of anxiety and pediatric chronic pain. A clinical sample of youth (aged 10-18 years) with chronic pain completed a measure of SPT at baseline and rated their anxiety and pain characteristics for seven consecutive days at baseline and at three-month follow-up. Multiple linear regression analyses were conducted to model whether SPT moderated the relationship between baseline anxiety and pain intensity, unpleasantness, and interference three months later. SPT significantly moderated the relationship between anxiety and pain intensity. High anxiety youth with high SPT reported increased pain intensity three months later, while high anxiety youth with low SPT did not. High anxiety youth who experience pain as potentially traumatizing are more likely to report higher pain intensity three months later than high-anxiety youth who do not. Future research should examine whether children's propensity to become traumatized by their pain predicts the development of chronic pain and response to intervention.

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.

Use of the Bogus Pipeline Increases Sexual Concordance in Women But Not Men.

Sexual concordance-the agreement between physiological (genital) and psychological (emotional) sexual arousal-is, on average, substantially lower in women than men. Following social role theory, the gender difference in sexual concordance may manifest because women and men are responding in a way that accommodates gender norms. We examined genital and self-reported sexual arousal in 47 women and 50 men using a condition known to discourage conformity to gender norms (i.e., a bogus pipeline paradigm). Participants reported their feelings of sexual arousal during a sexually explicit film, while their genital arousal (penile circumference, vaginal vasocongestion), heart rate (HR), and galvanic skin (GS) responses were recorded. Half of the participants were instructed that their self-reported sexual arousal was being monitored for veracity using their HR and GS responses (bogus pipeline condition; BPC); the remaining participants were told that these responses were recorded for a comprehensive record of sexual response (typical testing condition; TTC). Using multi-level modeling, we found that only women's sexual concordance was affected by testing condition; women in the BPC exhibited significantly higher sexual concordance than those in the TTC. Thus, we provide the first evidence that the gender difference in sexual concordance may at least partially result from social factors.

The hippocampal-to-ventricle ratio (HVR): Presentation of a manual segmentation protocol and preliminary evidence.

Disentangling age-related changes from developmental variations in hippocampal volume has proven challenging. This article presents a manual segmentation protocol for the hippocampal-to-ventricle ratio (HVR), a measure combining the assessment of hippocampal volume with surrounding ventricular volume. By providing in a single measure both a standard volumetric assessment of the hippocampus and an approximation of volume loss, based on ventricular enlargement, we believe the HVR provides a superior cross-sectional estimation of hippocampal structural integrity. In a first attempt to validate this measure, we contrasted the HVR and standard hippocampal volume in their associations with age and memory performance in two independent cohorts of healthy aging individuals. The first cohort consisted in 50 cognitively normal subjects (mean age: 66.8 years, SD: 4.96, range: 60-75 years), while the second cohort included 88 cognitively normal subjects (mean age: 65.06 years, SD: 6.42, range: 55-80 years). We showed that the manual segmentation protocol for the HVR can be implemented with high reliability. In both cohorts, the HVR showed stronger negative associations with age than standard hippocampal volume. Correlations with memory performance were also numerically superior with the HVR than standard hippocampal volume, across the two cohorts. These findings support an added benefit of using the HVR over standard hippocampal volume when examining relationships with age or memory function in aging individuals. Although further validation is required, we propose that the computation of the HVR is a promising method to improve the evaluation of hippocampal integrity from cross-sectional MR images.

The Relationship Between Sexual Functioning and Sexual Concordance in Women.

Previous research using clinical samples has shown a positive relationship between women's sexual functioning and sexual concordance (i.e., agreement between genital and subjective sexual arousal). We further examined this relationship using concurrent measures of vaginal, clitoral, and subjective sexual responses in a community sample of women (N = 64, with 59.4% and 34.1% reporting sexual desire and/or arousal difficulties, respectively). Contrary to studies using clinical samples, sexual desire and arousal difficulties were associated with stronger sexual concordance, specifically when changes in subjective arousal predicted changes in genital responses. The subjective experience of arousal may be particularly important in influencing genital responses in women with sexual desire and arousal difficulties compared to unaffected women.

Frequency of Penile-Vaginal Intercourse is Associated with Verbal Recognition Performance in Adult Women.

Previous studies have identified a number of factors that contribute to improved cognitive function, and to memory function specifically, in cognitively normal individuals. One such factor, frequency of penile-vaginal intercourse (PVI), has been reported in a number of animal studies to be advantageous to memory for previously presented objects by increasing neurogenesis in the dentate gyrus of the hippocampus. However, studies investigating the potential benefits of frequent PVI on memory function in young women are to the best of our knowledge absent from the literature. The current study thus investigated whether the self-reported frequency of sexual intercourse was related to memory function in healthy female college students. To determine whether variation in PVI would be associated with memory performance, we asked 78 heterosexual women aged 18-29 years to complete a computerized memory paradigm consisting of abstract words and neutral faces. Results showed that frequency of PVI was positively associated with memory scores for abstract words, but not faces. Because memory for words depends to a large extent on the hippocampus, whereas memory for faces may rely to a greater extent on surrounding extra-hippocampal structures, our results appear to be specific for memory believed to rely on hippocampal function. This may suggest that neurogenesis in the hippocampus is higher in those women with a higher frequency of PVI, in line with previous animal research. Taken together, these results suggest that PVI may indeed have beneficial effects on memory function in healthy young women.
