Welcome to Wonderland? A Population Study of Intimate Experiences and Safe Sex at a Transformational Mass Gathering (Burning Man).

Transformational festivals are socially immersive artistic mass gatherings that are said to promote a strong feeling of belonging and experiences of personal transformation. The purposes of the present study were (1) to investigate the social and intimate experiences of Burning Man participants and (2) to study the factors predicting safe sex practices in the context of that transformational festival. The study was based on data from two consecutive cycles (2013 and 2014) of the yearly post-event online survey done in collaboration with the Burning Man Project. Participants consisted of people who attended the event (N = 19,512). The results were weighted based on the sociodemographic characteristics of the population. A typology of social and intimate experiences was created using a k-means cluster analysis. Predictors of having had unprotected sex with someone met during the event were identified using a nested logistic regression. Five profiles of social and intimate experiences were identified. Profiles with high levels of emotionally and physically intimate experiences were associated with a strong feeling of belonging and a high proportion of personal transformation. Predictive analyses showed that unprotected sex was mainly predicted by variables associated with one of three factors: (1) a lower lever of preparation and practice in using protection, (2) sex education and/or subcultures, and (3) the perceived costs and benefits associated with protection. The results also indirectly suggest a positive effect of the event on safe sex. Implications in terms of public health intervention are discussed.

Validation of a Self-Report Questionnaire Assessing the Bodily and Physiological Sensations of Orgasm.

INTRODUCTION: Despite a plethora of research on sexual functioning during the past decades, the field is still lacking standardized measurements specifically characterizing orgasm. Although several validated tools are available to assess sexual function in healthy and clinical populations, items on orgasm are limited to frequency or dichotomous responses. A neurophysiologic model of orgasm developed from previous research in able-bodied and spinally injured populations offers a promising framework for the construction of a new questionnaire. AIM: To develop and validate a brief self-report measurement of orgasm by the assessment of bodily and physiologic sensations perceived during climax by able-bodied individuals. Although the currently available tool focuses on the phenomenological sensations associated with climax, the goal of this questionnaire was to capture the more specific genital and extragenital sensations associated with orgasm. MAIN OUTCOME MEASURES: The current Bodily Sensations of Orgasm questionnaire and the Orgasm Rating Scale. METHODS: Data from previous research conducted on individuals with spinal cord injury and the available empirical literature provided a pool of 45 items organized into four categories, which were reviewed by an expert panel. Upon review, a 28-item questionnaire was created and administered to a community sample of 227 participants, including men and women, 18 to 73 years old. RESULTS: Exploratory factor analyses supported the four-factor model, in which orgasm is comprised of extragenital sensations, genital sensations and spasms, nociceptive sensations, and sweating responses. Overall, a high degree of internal consistency was found for the final 22-item questionnaire (Cronbach α = 0.87), with individual reliability coefficients showing moderate to high internal consistency (r = 0.65-0.79) for each dimension. Overall temporal stability of the measurement was acceptable (r = 0.74). Using the Orgasm Rating Scale, satisfying convergent validity was confirmed, thereby indicating that the two measurements are complementary. CONCLUSION: The Bodily Sensations of Orgasm questionnaire allows for a brief evaluation of the physical and physiologic sensations associated with orgasm. Findings also suggest perceptual differences between men and women with regard to climax, with women reporting a larger repertoire of climactic sensations during orgasm.

Genital Sensory Detection Thresholds and Patient Satisfaction With Vaginoplasty in Male-to-Female Transgender Women.

INTRODUCTION: Gender-affirming surgery is common for the treatment of gender dysphoria, but its effect on genital sensitivity is not well known. AIMS: To investigate genital sensory detection thresholds in male-to-female transgender women postoperatively and their relation to psychological well-being and variables of satisfaction. METHODS: Prospective study on 28 transgender women at least 18 years old operated on at least 3 months before the study by a single surgeon (N.M.J.). MAIN OUTCOME MEASURES: Medical complications; sensory detection thresholds for light touch, pressure, and vibration; and questionnaires on general and sexual satisfaction, sexual function, depression, and psychological well-being. RESULTS: Sensory detection thresholds ranged from 0.07 to 2.82 g for light touch, with the neck being most sensitive; from 20.23 to 34.64 g for pressure, with similar results for the neck and clitoris; and from 0.0052 to 0.0111 V for vibration, with similar findings for all stimulation points. Satisfaction with the appearance of the labia, vulva, clitoris, and sexual function was good to very good. Frequency of sexual activities increased significantly postoperatively for orogenital stimulation and decreased significantly for frequency of fantasies (t = -4.81; P < .0001). Orgasmic function was reported by 80% of participants. Psychological adjustment was good to very good, with low depression scores. Sexual satisfaction was statistically and positively correlated with vaginal function and depth, clitoral sensation, appearance of the vulva and labia minora, and natural lubrication and negatively correlated with depression scores. CONCLUSION: Gender-affirming surgery yields good results for satisfaction with appearance and function. Genital sensitivity showed the best results with pressure and vibration.

The assessment of sensory detection thresholds on the perineum and breast compared with control body sites.

INTRODUCTION: Few studies explored multiple sensory detection thresholds on the perineum and breast, but these normative data may provide standards for clinical conditions such as aging, genital and breast surgeries, pathological conditions affecting the genitals, and sexual function. AIMS: The aim of this study was to provide normative data on sensory detection thresholds of three sensory modalities on the perineum and breast. METHODS: Thirty healthy women aged between 18 and 35 years were assessed on the perineum (clitoris, labia minora, vaginal, and anal margin), breast (lateral, areola, nipple), and control body locations (neck, forearm, abdomen) for three sensory modalities (light touch, pressure, vibration). MAIN OUTCOME MEASURES: Average detection thresholds for each body location and sensory modality and statistical comparisons between the primary genital, secondary sexual, and neutral zones were the main outcome measures. RESULTS: Average detection thresholds for light touch suggest that the neck, forearm, and vaginal margin are most sensitive, and areola least sensitive. No statistical difference is found between the primary and secondary sexual zones, but the secondary sexual zone is significantly more sensitive than the neutral zone. Average detection thresholds for pressure suggest that the clitoris and nipple are most sensitive, and the lateral breast and abdomen least sensitive. No statistical difference is found between the primary and secondary sexual zone, but they are both significantly more sensitive than the neutral zone. Average detection thresholds for vibration suggest that the clitoris and nipple are most sensitive. The secondary sexual zone is significantly more sensitive than the primary and neutral zone, but the latter two show no difference. CONCLUSION: The current normative data from sensory detection threshold are discussed in terms of providing standard values for research and clinical conditions. Additional analysis from breast volume, body mass index, hormonal contraception, menstrual cycle, and sexual orientation do not seem to influence the results. Sexual abstinence and body piercing may have some impact.

A life-course and time perspective on the construct validity of psychological distress in women and men. Measurement invariance of the K6 across gender.

BACKGROUND: Psychological distress is a widespread indicator of mental health and mental illness in research and clinical settings. A recurrent finding from epidemiological studies and population surveys is that women report a higher mean level and a higher prevalence of psychological distress than men. These differences may reflect, to some extent, cultural norms associated with the expression of distress in women and men. Assuming that these norms differ across age groups and that they evolve over time, one would expect gender differences in psychological distress to vary over the life-course and over time. The objective of this study was to investigate the construct validity of a psychological distress scale, the K6, across gender in different age groups and over a twelve-year period. METHODS: This study is based on data from the Canadian National Population Health Survey (C-NPHS). Psychological distress was assessed with the K6, a scale developed by Kessler and his colleagues. Data were examined through multi-group confirmatory factor analyses. Increasing levels of measurement and structural invariance across gender were assessed cross-sectionally with data from cycle 1 (n = 13019) of the C-NPHS and longitudinally with cycles 1 (1994-1995), 4 (2000-2001) and 7 (2006-2007). RESULTS: Higher levels of measurement and structural invariance across gender were reached only after the constraint of equivalence was relaxed for various parameters of a few items of the K6. Some items had a different pattern of gender non invariance across age groups and over the course of the study. Gender differences in the expression of psychological distress may vary over the lifespan and over a 12-year period without markedly affecting the construct validity of the K6. CONCLUSIONS: This study confirms the cross-gender construct validity of psychological distress as assessed with the K6 despite differences in the expression of some symptoms in women and in men over the life-course and over time. Findings suggest that the higher mean level of psychological distress observed in women reflects a true difference in distress and is unlikely to be gender-biased. Gender differences in psychological distress are an important public health and clinical issue and further researches are needed to decipher the factors underlying these differences.

Effect of a psychoneurotherapy on brain electromagnetic tomography in individuals with major depressive disorder.

Recent advances in power spectral analysis of electroencephalography (EEG) signals and brain-computer interface (BCI) technology may significantly contribute to the development of psychoneurotherapies. The goal of this study was to measure the effect of a psychoneurotherapy on brain source generators of abnormal EEG activity in individuals with major depressive disorder (MDD). Thirty participants with unipolar MDD were recruited in the community. The proposed psychoneurotherapy was developed based on the relationship between the localization of abnormal EEG activity and depressive symptomatology. Brain electromagnetic abnormalities in MDD were identified with low resolution brain electromagnetic tomography (LORETA) and a normative EEG database. Localization of brain changes after treatment was assessed through the standardized version of LORETA (sLORETA). Before treatment, excessive high-beta (18-30 Hz) activity was noted in several brain regions located in the fronto-temporal regions. After treatment, only participants who successfully normalized EEG activity in cortico-limbic/paralimbic regions could be considered in clinical remission. In these regions, significant correlations were found between the percentage of change of depressive symptoms and the percentage of reduction in high-beta activity. These results suggest that the normalization of high-beta activity in cortico-limbic/paralimbic regions can be associated with a significant reduction of depressive symptoms.

Predicting the affective tone of everyday dreams: A prospective study of state and trait variables.

Although emotions are reported in a large majority of dreams, little is known about the factors that account for night-to-night and person-to-person variations in people's experience of dream affect. We investigated the relationship between waking trait and state variables and dream affect by testing multilevel models intended to predict the affective valence of people's everyday dreams. Participants from the general population completed measures of personality and trauma history followed by a three-week daily journal in which they noted dream recall, valence of dreamed emotions and level of perceived stress for the day as well as prior to sleep onset. Within-subject effects accounted for most of the explained variance in the reported valence of dream affect. Trait anxiety was the only variable that significantly predicted dream emotional valence at the between-subjects level. In addition to highlighting the need for more fine-grained measures in this area of research, our results point to methodological limitations and biases associated with retrospective estimates of general dream affect and bring into focus state variables that may best explain observed within-subject variance in emotions experienced in everyday dreams.

Smoking behaviours among heterosexual and sexual minority youth? Findings from 15 years of provincially representative data.

INTRODUCTION AND AIMS: Sexual identity disparities in smoking behaviours are well established; however, there is limited research on whether these disparities have diminished as the social and political landscape has changed for lesbian, gay and bisexual people. Thus, we examined changes in prevalence and sexual identity disparities in three smoking behaviours among Canadian adolescents from 1998 to 2013. DESIGN AND METHODS: Data are from the provincially representative British Columbia Adolescent Health Survey (N = 99 373). Using sex-stratified, age-adjusted logistic regression models, we estimated: (i) trends in lifetime cigarette use, early onset, and past 30-day use for heterosexual and three subgroups of sexual minority (i.e. mostly heterosexual, bisexual and gay/lesbian) youth; (ii) sexual identity disparities in these cigarette-related behaviours within each survey year (1998, 2003, 2008, 2013); and (iii) whether the size of the disparity has changed from 1998 to 2013. RESULTS: Smoking has declined for all youth from 1998 to 2013, although less consistently for sexual minority youth. Within-year disparity estimates indicated elevated prevalence of cigarette use for sexual minority compared to heterosexual youth, particularly among females. Trends in sexual identity and smoking behaviours indicated that the degree of differences between heterosexual and sexual minority youth have remained stable or, in some cases, widened. Heterosexual and sexual minority youth differences widened for early onset among sexual minority boys and lifetime and past 30-day use for sexual minority girls. DISCUSSION AND CONCLUSIONS: Efforts to prevent smoking behaviours among youth should continue. Tailored preventive strategies for sexual minority youth might help address existing disparities.

Empowering Malian women living with HIV regarding serostatus disclosure management: Short-term effects of a community-based intervention.

OBJECTIVE: The objective of this study was to assess the short-term effects of Gundo-So-a program aimed at empowering Malian women living with HIV (WLHIV) regarding serostatus disclosure management. METHODS: A pre-experimental study with two measures (one week before and four weeks after Gundo-So) was carried out. A 35-item questionnaire was administered to a convenience sample of 210 WLHIV. Six outcomes were considered: ability to decide whether or not to disclose HIV status, self-efficacy to keep HIV status a secret, self-efficacy to disclose HIV status, feeling crushed by the weight of secrecy, perceived physical health, and perceived psychological health. For each outcome, temporal changes associated with the intervention were assessed using linear regressions with random intercepts. RESULTS: Statistically significant change was observed for all six outcomes between the pre- and post-intervention measures. Furthermore, several variables were associated with the baseline levels of the outcomes and the intervention effect. CONCLUSION: The results suggest that Gundo-So empowers Malian WLHIV with regard to serostatus disclosure management, thus improving their perceived physical and psychological health. PRACTICAL IMPLICATIONS: These results highlight the need for programs to empower WLHIV regarding serostatus disclosure, so that WLHIV can make free and informed decisions regarding serostatus disclosure.

Women with PTSD benefit more from psychotherapy than men.

OBJECTIVE: This study aimed to examine possible gender differences in therapy gain in patients with posttraumatic stress disorder (PTSD). It also aimed to examine whether the gender effect could be explained by gender differences in dropout rates, trauma type (interpersonal/noninterpersonal), or context of the event (work-related/not work-related). METHOD: Seventy-one participants received 20-session cognitive-behavior therapy for PTSD. They were assessed pre- and posttreatment on primary and secondary outcome measures: PTSD symptoms, quality of life, avoidance, social support and positive reappraisal copings, and supportive and countersupportive interactions. RESULTS: Regression analysis showed that gender explained 6%-9% significant variance in the outcome: Women statistically benefited more from the treatment than men on quality of life (p < .05), avoidance (p < .01), and support seeking (p < .05) copings, supportive (p < .05), and countersupportive (p < .05) interactions. However, there was no statistically significant gender difference on PTSD symptoms and positive reappraisal coping. Dropout rate, trauma type, and context of trauma could not explain the gender differences. CONCLUSION: The results might explain ambiguous previous results on gender differences in therapy efficacy for PTSD, and highlight the importance of using multiple measurements in the evaluation of treatment outcome in PTSD. Further research is needed to explain the exact mechanisms behind women's getting more of therapy's secondary benefits. (PsycINFO Database Record

Predictors of posttraumatic stress disorder among police officers: A prospective study.

This prospective study examined risk and protective factors in the development of posttraumatic stress disorder (PTSD) in a sample of 83 police officers. Structured interviews were conducted in order to assess the most recent work-related traumatic event and establish diagnoses of acute stress disorder (ASD) and full or partial PTSD. Police officers were assessed between 5 and 15 days, and at 1 month, 3 months, and 12 months after the event. They also completed self-administered questionnaires assessing several potential predictors. Predictive analyses about the onset of PTSD were based on a 4-step nested random-effect linear regression. Overall, results showed that the modulation of PTSD symptomatology was associated with some pretraumatic (i.e., emotional coping strategies and number of children), peritraumatic (i.e., physical and emotional reactions and dissociation), and posttraumatic factors (i.e., ASD, depression symptoms, and seeking psychological help at the employee assistance program and at the police union between the event and Time 1). Clinical implications of these findings are discussed and key directions for future studies are proposed.

HIV serostatus disclosure: development and validation of indicators considering target and modality. Results from a community-based research in 5 countries.

RATIONALE: HIV serostatus disclosure is a complex challenge for persons living with HIV (PLHIV). Despite its beneficial effects, it can also lead to stigmatization and rejection. The current lack of multi-dimensional measurement tools impede an in-depth understanding of the dynamic of disclosure. OBJECTIVE: To develop and validate complex measures of serostatus disclosure. METHODS: This international community based research study was performed by joint research teams (researchers/community based organizations (CBO)) in five countries (Democratic Republic of the Congo, Ecuador, Mali, Morocco and Romania). A convenience sample of 1500 people living with HIV (PLHIV) in contact with local CBO were recruited in 2011 (300 in each country). Face-to-face interviews were performed using a 125-item questionnaire covering HIV status disclosure to 23 potential disclosure targets and related issues (including personal history with HIV, people's reaction to disclosure, sexuality). A principal component analysis and a hierarchical cluster analysis were performed, in order to identify the main components of HIV disclosure, create measures and classify participants into profiles. RESULTS: Patterns of disclosure were summarized using two main measures: direct and indirect disclosure. Disclosure to sexual partners, whether steady or not, was different from patterns of disclosure to other targets. Among the participants, three profiles emerged - labelled Restricted disclosure, Mainly indirect disclosure and Mainly direct disclosure, respectively representing 61%, 13% and 26% of the total sample. The profiles were associated with different aspects of PLHIV's lives, including self-efficacy, functional limitations and social exclusion. Patterns varied across the five studied countries. CONCLUSION: Results suggest that multi-dimensional constructs should be used to measure disclosure in order to improve understanding of the disclosure process.

Assessment of the Psychosocial Predictors of Health-Related Quality of Life in a PTSD Clinical Sample.

Although a wide array of the scientific literature explores the links between posttraumatic stress disorder (PTSD) symptoms, coping strategies, and social support and health-related quality of life (HRQoL) as an outcome variable, their connections remain unclear. It is unknown whether PTSD symptom severity, coping strategies, and social support explain each a unique portion of variance of HRQoL of individuals with PTSD. In the current study, based on pretreatment results of a broader study assessing a specific intervention for PTSD, 94 individuals with PTSD were screened for psychiatric disorders and completed several questionnaires concerning social support, coping strategies, PTSD symptoms, and HRQoL. Coping strategies, social support, and PTSD all appeared to be predictors of HRQoL; however, PTSD seemed to constitute the major predictor among these variables. Indeed, coping strategies and social support did not explain a unique share of variability of HRQoL beyond that of PTSD symptomatology. A causal pathway integrating these variables should be tested in future studies.

Psychological distress in Canada: the role of employment and reasons of non-employment.

BACKGROUND: This study investigated variations in psychological distress in a large sample of the Canadian population according to employment status, occupation, work organization conditions, reasons for non-employment, stress and support outside the work environment, family situation and individual characteristics. METHODS: Data came from cycle 4 (2000-1) of the Canadian National Population Health Survey conducted by Statistics Canada. Multiple regression analyses, adjusted for the family situation, the level of support from the social network and the individual characteristics, were carried out on a sample of 7258 individuals aged from 18 to 65 years. RESULTS: Occupation, social support at work, age, self-esteem, presence of children aged five and under and social support outside of the workplace were associated with lower levels of psychological distress, while permanent and temporary disability, psychological demands in the workplace, job insecurity, female gender, and stressful financial, marital and parental situations were related to higher levels of psychological distress. CONCLUSIONS: Findings from this study suggest that, in terms of psychological distress, having a job is not always better than non-employment, and that specific non-employment situations associate differently with psychological distress.

Relative Efficacy of Cognitive-Behavioral Therapy Administered by Videoconference for Posttraumatic Stress Disorder: A Six-Month Follow-Up.

Until recently, only one study was published on cognitive-behavioral therapy (CBT) of posttraumatic stress disorder (PTSD) in individual therapy via videoconference (Germain, Marchand, Bouchard, Drouin, & Guay, 2009); however, it only assessed the posttreatment effect. This study presents the follow-up of Germain et al.'s (2009) study. The main goal was to compare the effectiveness after six months of CBT for PTSD either face-to-face (n = 24) or by videoconference (n = 12). Each participant received CBT for 16 to 25 weeks and completed various questionnaires before and after treatment and at a six-month follow-up. The two treatments had equivalent levels of symptom reduction (Modified PTSD Symptom Scale: η2 < 0.01, p > .05) and proportion of patients with a clinically significant change in symptoms (42% for face-to-face vs. 38% for videoconferencing, p > .05). Thus, CBT for PTSD via videoconference seems to be a viable alternative when adequate face-to-face treatments are less available.

How Do Social Interactions with a Significant Other Affect PTSD Symptoms? An Empirical Investigation with a Clinical Sample.

Social support and coping are both related to posttraumatic stress disorder (PTSD) symptoms, but the mechanisms underlying their relationships remain unclear. This study explores these relationships by examining the perceived frequency of supportive and countersupportive interactions with a significant other in PTSD patients. Ninety-six participants with PTSD were recruited and completed questionnaires assessing social interactions, ways of coping, and PTSD symptoms. Associations of social interactions (r2 = 4.1%-7.9%, p < .05) and coping (r2 = 15.9%-16.5%, p < .001) with symptoms were independent, and suggested a direct association between social interactions and PTSD. Countersupportive interactions were more associated to symptoms than supportive interactions. Our findings suggest the development of psychotherapies that integrate social support interventions.

Absorption, psychological boundaries and attitude towards dreams as correlates of dream recall: two decades of research seen through a meta-analysis.

Many studies have reported positive correlations between dream recall frequency (DRF) and measures of absorption, psychological boundaries and attitude towards dreams. A majority of these studies, however, have relied exclusively on retrospective measures of DRF even though daily dream logs are generally considered to be more direct and valid measures of DRF. The first goal of the present meta-analysis was to evaluate the effect sizes of three variables (absorption, psychological boundaries and attitude towards dreams) as correlates of DRF. The second goal was to evaluate if these effect sizes varied as a function of how DRF was operationalized (i.e. retrospective measure versus dream log). Data from 24 studies were included in the analyses. For each of the three variables investigated, correlations with retrospective measures of DRF were of greater magnitude than those obtained with daily logs. These results indicate that scores on measures of absorption and psychological boundaries are not related to DRF per se, but rather to people's tendency to retrospectively underestimate or overestimate their DRF, while attitude towards dreams is related both to DRF per se and to people's retrospective estimation bias. Implications of these findings for dream research are discussed.
