Interpersonal Transactions and Responses to Cold Pressor Pain among Australian Women and Men

This study was designed to assess how interpersonal transactions affect responses to painful stimulation among Australian women and men. Participants were 69 women and 49 men, randomly assigned to a No Transaction (NT) condition (coping alone) or one of three experimenter-initiated transactions (Distraction, Pain-Monitoring, Re-interpretation). Significant sex × transaction interactions for pain tolerance and reported pain revealed that pain responses of men did not differ as a function of transaction. However, women who coped alone had significantly less tolerance and more pain than men and women in other groups. In contrast, women engaged in re-interpretation transactions fared better on measures of pain perception than women engaged in distraction transactions, and they reported significantly less catastrophizing than did men in the re-interpretation condition. Together, findings replicate and extend recent evidence that suggests that women’s responses to noxious stimuli vary considerably as a result of interpersonal context.     

Pain intensity and pain unpleasantness in triathletes: A study examining their associations with pain catastrophizing and pain expectations

ObjectiveTriathletes represent a growing and unique population of individuals willing to endure significant mental and physical stress to practice the sport they love. However, little is known about the pain experienced while training for and competing in a triathlon and how psychological factors influence this experience. This study will assess pain experienced by triathletes in training and competition, and investigate the association between pain catastrophizing and pain expectations with triathlon pain intensity and pain unpleasantness.DesignIn this observational study, a sample of 261 triathletes completed two online surveys before and after participating in a triathlon.ResultsModerate levels of pain intensity and pain unpleasantness were reported during training and competition. Pain catastrophizing was positively associated with expected and actual triathlon pain unpleasantness, but not with pain intensity. Expected pain intensity was also significantly associated with pain intensity experienced while competing, whereas expected pain unpleasantness was significantly related to both triathlon pain intensity and unpleasantness. Finally, regression analysis revealed pain catastrophizing and pain expectations to be unique predictors of triathlon pain intensity and pain unpleasantness.ConclusionThis study highlights the important role of psychological factors in triathletes' experience of pain and could eventually help tailor interventions aimed at improving the practice of triathlon.     

Pain perception across the menstrual cycle phases in women with chronic pain

The menstrual cycle has been reported to alter pain perception but the patterns differ among studies. It has been reported that estrogens may influence somatic sensory processes. The present aim was to investigate whether the perception of pain varies by phases of the menstrual cycle. 20 women with chronic low pain volunteered to participate and were asked to rate their pain each day during three successive menstrual cycles. The menstrual cycle was divided into four and five phases to be able to compare results. Analysis showed there were phase differences in pain ratings during the menstrual cycle. Regardless of whether the menstrual cycle was divided into four or five phases, women rated pain significantly higher in the menstrual and premenstrual phases than in the midmenstrual and ovulatory phases. This is consistent with other studies showing less pain sensitivity during phases of the menstrual cycle associated with high estrogen. Women with high pain frequency reported more frequently a passive coping style and catastrophizing thoughts.     

Sexual activity is inversely related to women’s perceptions of the facial attractiveness of unknown men

A study was conducted to assess whether individual differences in sexual activity during the past 30 days, in particular penile–vaginal intercourse (PVI; which is associated with measures of relationship quality), are related to the perception of the facial attractiveness of unknown men. Forty-five women reported the frequency of a variety of sexual behaviors and rated the facial attractiveness and friendliness of 24 men. Women who reported more frequent orgasm from masturbation rated men as less friendly. This finding might be reflective of the more anti-social attitude associated with more frequent masturbation. The results also show that women who engaged more frequently in most kinds of sexual behavior, not only PVI, considered unknown men to be less facially attractive. That is, individuals who engage more frequently in a variety of sexual behaviors with their partner perceived unknown men as less attractive and thereby may be less susceptible to the lure of other (or if the only sexual behavior is masturbation, any) men.     

Comparing the body to superior others: Associations with daily exercise and body evaluation in men and women

ObjectivesThis study tested the link between daily body-related upward social comparisons (BUSCs) and exercise behavior, and examined how appearance evaluation and gender may impact this association.MethodIn a weeklong assessment, 87 participants (54% women) completed daily retrospective measures of social comparisons and exercise behavior, and a one-time trait measure of appearance evaluation.ResultsBased on findings from hierarchical linear modeling, men with more negative appearance evaluations reported higher exercise engagement on days when they made more (compared to less) BUSCs. Meanwhile, women with more negative appearance evaluations reported less exercise engagement on days when they engaged in more (compared to less) BUSCs.ConclusionsAmong individuals who experience negative appearance evaluations, upward body comparisons are associated with more exercising among men, and lower exercise among women. BUSCs have an important role in promoting adaptive exercise behaviors and managing negative body image.

Catastrophizing,locus of control,pain, and disability in chinese chronic low back pain patients

Abstract

The present study examined the associations of locus of control (LOC) and catastrophizing with pain intensity and disability in Chinese chronic low back pain (CLBP) patients. In the study, 56 respondents (21 men and 35 women) with a mean age of 36.98 years (SD= 12.22) completed measures assessing locus of control, catastrophizing tendency, pain intensity, disability, and psychological distress. Results showed that after partialling out the effects of gender, duration of pain, and psychological distress, internal LOC significantly explained the variance of disability. For pain intensity, only catastrophizing accounted for a large portion of the variance. Limitations of the study and suggestions for future work were discussed.     

It is better to smile to women: Gender modifies perception of honesty of smiling individuals across cultures

Social perception studies have revealed that smiling individuals are perceived more favourably on many communion dimensions in comparison to nonsmiling individuals. Research on gender differences in smiling habits showed that women smile more than men. In our study, we investigated this phenomena further and hypothesised that women perceive smiling individuals as more honest than men. An experiment conducted in seven countries (China, Germany, Mexico, Norway, Poland, Republic of South Africa and USA) revealed that gender may influence the perception of honesty in smiling individuals. We compared ratings of honesty made by male and female participants who viewed photos of smiling and nonsmiling people. While men and women did not differ on ratings of honesty in nonsmiling individuals, women assessed smiling individuals as more honest than men did. We discuss these results from a social norms perspective.     

The Relationship Between Socialization and Antisocial Behavior,Substance Use,and Family Conflict in College Students

Gough's (1960) Socialization (So) scale has been widely used as a measure of the extent to which societal values are internalized. It is well documented that antisocial individuals evidence low So scores but less clear that low So scores predict antisocial behavior in nonclinical samples Two studies conducted at different universities in different geographical regions and different decades provided evidence consistent with this hypothesis. Results from Study 1 revealed that self-reports of several types of antisocial behavior and substance use were significantly more common among Low-So than High-So undergraduate men and women. Study 2 replicated principal findings for both men and women using correlational analyses. In addition, Study 2 yielded a significant relation between low So scores and greater family conflict as well as several gender differences reflecting stronger correlations in men than in women. These findings indicate substantial generality for the relations between socialization and antisocial behavior, especially in men, and are consistent with the use of the So scale to identify subjects who share important characteristics with criminal or psychopathic groups.     

A Status Account of Gender Stereotypes: Beyond Communality and Agency

Women's lower status relative to men can account for people's differential attribution to women and men, of the constructs of the Extended Personal Attributes Questionnaire (EPAQ; Spence, Helmreich, & Holahan, 1979). Ratings in all three studies were made on the EPAQ scales. In Study 1a, participants rated their perceptions of the stereotypes of women and of men. In Study 1b, participants reported their own perceptions of women and men. In Study 2, participants were presented a minimal status manipulation (Conway, Pizzamiglio, & Mount, 1996) for which status is unconfounded with gender; participants then reported their perceptions of low- and high-status individuals. The men in Studies 1a and 1b were perceived as were high-status individuals in Study 2. Except for (i.e., verbal passive-aggression nagging, whining), women in Studies 1a and 1b were perceived as were low-status individuals in Study 2. Results are discussed in terms of status accounts of gender stereotypes and gender differences in social behavior.     

Assessing the relationship between cold pressor pain responses and dimensions of the anxiety sensitivity profile in healthy men and women

Anxiety sensitivity (AS) has been shown previously to be an important factor in the perception and experience of experimentally induced pain within healthy adults. The aim of the current study was to extend this research by: (i) using the Anxiety Sensitivity Profile (ASP) as an alternative measure of AS; (ii) examining whether different coping instructions affect pain reports; and (iii) investigating potential differences between men and women. Participants were 50 healthy adults (23 males, 27 females) who were required to complete 2 versions of the cold pressor pain task; one version required the use of control instructions, whereas the other made use of acceptance-based instructions. Although the coping instructions were found to affect pain thresholds (acceptance resulted in lower thresholds), a similar pattern of correlations were found between the pain indexes and AS under both conditions. Of the ASP subscales, the gastrointestinal and cognitive concerns components were found to be the most strongly related to pain experiences. When the analysis was conducted separately for each sex, the ASP scales were related to the self-report measures of pain in women, whereas they were related to the behavioural measures of pain in men. These results not only confirm that AS is associated with experimental pain, but that there may be sex differences in this relationship.     

Depression history and coping with chronic pain: a daily process analysis.

This study examined how a previous episode of depression is related to daily pain and reactions to pain among individuals with fibromyalgia, a chronic pain syndrome. Seventy-one women with fibromyalgia (including 30 who were previously depressed) rated their pain and mood 3 times daily for 30 days. Each night, participants rated the extent to which they responded to pain by catastrophizing, how much control they had over that day's pain, their ways of coping with pain that day, and the effectiveness of their coping efforts. Multivariate multilevel regression models revealed that after controlling for neuroticism and current depressive symptoms, formerly depressed and never-depressed individuals differed in how they coped with increased pain and in how they appraised the efficacy of their coping efforts. Formerly depressed participants who also reported more current depressive symptoms showed a greater decline in pleasant mood on more painful days than did formerly depressed participants who were experiencing fewer current depressive symptoms. These findings illustrate how a history of depression can be captured in the dynamics of daily life.     

Étude des liens entre la fréquence de pratique sportive et la santé des étudiants : mesure des effets de genre sur les troubles alimentaires et les consommations de substances

A number of previous studies have focused on the effect of sport practice on eating disorders and substance use. Most of these studies suggest that among students sport practice is related to low levels of health issues like eating disorders and substance use. However, there is a relative dearth of evidence for these relationships and previous findings are based on comparisons between people involved in sport practice and physical activity and sedentary or largely inactive people. The present study aims to test the effects of frequency of sport practice on college students’ eating disorders and substance use when also controlling for gender effects.MethodsOne thousand and seventy-three first year college students (35.6% boys, 64.4% girls) volunteered to participate in the study. Participants were divided into three groups according to the frequency of their sport practice: students who rarely participated in sport practice (less than one hour a week and not every week; 406 students, 26.4% boys vs 73.6% girls), students who frequently participated in sport practice (every week but less than eight hours a week; 173 students, 33.5% boys vs 66.5% girls), and students who had intensive sport practice (eight hours a week or more; 494 students, 43.9% boys vs 56.1% girls). Alcohol, tobacco and cannabis use were assessed using the Alcohol Smoking and Substance Involvement Screening Test (ASSIST). Three different categories of eating disorders (Dieting, Bulimia, Oral control) were assessed using the EAT-26 inventory. ANOVAs were computed to test for gender differences across the three sport practice groups.ResultsResults of univariate ANOVAs revealed main effects for gender and sport practice on some of the substance use and eating disorder variables, ANOVA with multiple comparisons (Tamhan T Test) revealed a significant interaction effect of sport practice and gender on oral control and tobacco use. For girls, oral control and tobacco use do not vary within the three groups of sport practice whereas for boys the more frequent the sport practice, the lower their scores on oral control and tobacco use. For oral control, boys reported significantly higher scores than girls only when sport practice was rare. For tobacco use, boys reported significantly higher scores than girls when sport practice was rare and lower scores when sport practice was intensive.ConclusionThese results suggest that the positive effects of sport practice vary by gender and that the campaigns for promotion of physical activity might assist in the prevention of health issues amongst students but should be adapted according to the gender of the participants.     

Assessing the Relationship Between Cold Pressor Pain Responses and Dimensions of the Anxiety Sensitivity Profile in Healthy Men and Women

Anxiety sensitivity (AS) has been shown previously to be an important factor in the perception and experience of experimentally induced pain within healthy adults. The aim of the current study was to extend this research by: (i) using the Anxiety Sensitivity Profile (ASP) as an alternative measure of AS; (ii) examining whether different coping instructions affect pain reports; and (iii) investigating potential differences between men and women. Participants were 50 healthy adults (23 males, 27 females) who were required to complete 2 versions of the cold pressor pain task; one version required the use of control instructions, whereas the other made use of acceptance‐based instructions. Although the coping instructions were found to affect pain thresholds (acceptance resulted in lower thresholds), a similar pattern of correlations were found between the pain indexes and AS under both conditions. Of the ASP subscales, the gastrointestinal and cognitive concerns components were found to be the most strongly related to pain experiences. When the analysis was conducted separately for each sex, the ASP scales were related to the self‐report measures of pain in women, whereas they were related to the behavioural measures of pain in men. These results not only confirm that AS is associated with experimental pain, but that there may be sex differences in this relationship.     

Are Transgender Persons at Higher Risk for HIV Than Other Sexual Minorities? A Comparison of HIV Prevalence and Risks

SUMMARY

Recent studies have shown that transgender people are at high risk for HIV. Few studies, however, have directly compared the HIV risks and sexual health of transgender persons with that of other sexual minority populations. This study used baseline data of intervention studies targeting transgender persons, men who have sex with men, and women who have sex with women and men to compare their HIV risk behavior and sexual health. No significant differences were found between transgender persons and nontransgender men or women in consistent condom use or attitudes toward condom use. Transgender persons were less likely to have multiple partners and more likely to be monogamous than men who have sex with men; no differences were found between transgender persons and the women in this respect. When combining data on condom use, monogamy, and multiple partners, transgender persons did not differ from either nontransgender group in their overall risk for HIV. Transgender persons were less likely than the men or the women to have been tested for HIV. With regard to HIV prevalence, 17% of the men compared to only one transgender person and none of the women reported being HIV-positive. Transgender persons were also less likely than men who have sex with men to use drugs; no differences were found in the use of alcohol. However, with regard to mental health, transgender persons were more likely than the men to have experienced depression and more likely than men or women to have considered or attempted suicide. Finally, transgender persons reported the lowest levels of support from family and peers. Thus, in our sample, transgender persons appear to be at lower risk for HIV but at higher risk for mental health concerns than men who have sex with men. Remarkably few differences were found between transgender persons and women who have sex with women and men-a finding which might reflect the impact of social stigma on sexual health and have implications for the design of future HIV/STI prevention efforts.     

Sexual Peak: Socially Shared Cognitions About Desire,Frequency, and Satisfaction in Men and Women

Is a man’s sexual peak earlier than a woman’s? Three studies were conducted to examine (a) whether the perception that men achieve their sexual peak at a younger age than do women is shared across individuals of different ages and sexes, (b) whether sexual peak is defined differently for men and women, and (c) whether differences between definitions contribute to differences in the age at which men and women are perceived to reach sexual peak. Study 1 suggested that participants believed that females reach their sexual peak at an older age than do males. Study 2 indicated that the defining feature of sexual peak for males was sexual desire and for females was sexual satisfaction. Study 3 suggested that predictions of male sexual peak coincided with participants’ predictions of male age of highest desire and frequency, but not satisfaction, and that female sexual peak coincided with participants' predictions of female age of highest satisfaction but not frequency or desire. Discussion focuses on potential reasons for differences between the perception of male and female sexuality, as well as the social and evolutionary importance of each of the dimensions of sexuality for both males and females.     

Sex differences in cognition in healthy elderly individuals

ABSTRACT

Sex differences in patterns of cognitive test performance have been attributed to factors, such as sex hormones or sexual dimorphisms in brain structure, that change with normal aging. The current study examined sex differences in patterns of cognitive test performance in healthy elderly individuals. Cognitive test scores of 957 men and women (age 67–89), matched for overall level of cognitive test performance, age, education, and depression scale score, were compared. Men and women were indistinguishable on tests of auditory divided attention, category fluency, and executive functioning. In contrast, women performed better than men on tests of psychomotor speed and verbal learning and memory, whereas men outperformed women on tests of visuoconstruction and visual perception. Our finding that the pattern of sex differences in cognition observed in young adults is observed in old age has implications for future studies of both healthy elderly individuals and of those with cognitive disorders.     

Pain thresholds,pain-induced frontal alpha activity and pain-related evoked potentials are associated with antisocial behavior and aggressiveness in athletes

ObjectivesDeficiencies in perceptual and cognitive functions have been linked with antisocial and aggressive behavior. To test whether these putative relationships generalize to sport – a context where such behavior is common – we determined the extent to which pain thresholds and cortical activity in response to painful electrical stimulation were associated with antisocial and aggressive behavior in sport; we also examined their link to moral disengagement.DesignA cross-sectional design was used.MethodNinety-four participants completed questionnaires, had their pain threshold determined, and then had their central and frontal pain-related cortical activity recorded while they were electrically stimulated at supra-threshold intensity.ResultsSubjective pain thresholds were positively related while pain induced frontal alpha power was negatively related to antisocial behavior and aggressiveness. Central pain evoked potential amplitudes were negatively related to aggressiveness and moral disengagement.ConclusionsSensitivity to and cortical processing of noxious stimuli were reduced in individuals who more frequently behave antisocially and aggressively when playing sport and who are more likely to use psychosocial maneuvers to justify their harmful behavior. Our findings reveal that pain-related deficits are a feature of individuals who engage in more frequent antisocial and aggressive behavior in the context of sport.     

Sex Differences in the Presentation of Chronic Low Back Pain

Sex differences in 351 patients with chronic low back pain were examined. Biological, psychological, and psychosocial factors were considered. Sex differences in adaptive functioning were consistent with traditional gender roles. Significant interactions were found for sex and employment status, and sex and marital status. Retired women reported more pain and less activity than retired men. Retired men reported the least pain of any group. Outdoor work and social activities show opposite within–group patterns for men and women when stratified by employment status. Marriage was associated with more household work for women and less for men. The financial and social contexts of employment status and marriage are different for men and women. Results suggest the treatment of women with chronic low back pain requires attention to work in the home and the financial and social context of work outside the home.     

Women in the midluteal phase of the menstrual cycle have difficulty suppressing the processing of negative emotional stimuli: An event-related potential study

Emotion regulation deficits have been implicated in anxiety and depressive disorders, and these internalising disorders are more prevalent in women than men. Few electrophysiological studies have investigated sex differences in emotional reactivity and emotion regulation controlling for menstrual phase. Event-related potentials (ERPs) were recorded from 28 early follicular women, 29 midluteal women, and 27 men who completed an emotion regulation task. A novel finding of increased N2 amplitude during suppression was found for midluteal women compared with men. These findings suggest midluteal women may be significantly less able to suppress cortical processing of negative stimuli compared to men. This ERP finding was complemented by behavioral ratings data which revealed that while both early follicular and midluteal women reported more distress than men, midluteal women also reported greater effort when suppressing their responses than men. P1 and N1 components were increased in midluteal women compared to men regardless of instructional set, suggesting greater early attentional processing. No sex or menstrual phase differences were apparent in P3 or LPP. This study underscores the importance of considering menstrual phase when examining sex differences in the cortical processing of emotion regulation and demonstrates that midluteal women may have deficits in down-regulating their neural and behavioural responses.
