Women Who Experience More Affectionate Touch Report Better Body Satisfaction and Relationship Outcomes.

Affectionate touch (e.g. hugging, handholding) is an essential component of many intimate relationships and is a primary contributor to overall relationship satisfaction as well as sexual satisfaction. Affectionate touch is understood to be a form of non-verbal communication in which the giver is expressing positive feelings toward the receiver. Here, we propose that affectionate touch also positively impacts receivers' body satisfaction, because affectionate touch is a positive message communicated toward the receiver's body. In a cross-sectional sample of romantically partnered women (N = 1,156), we assessed the association between affectionate touch frequency and body satisfaction. We also investigated whether affectionate touch is associated with relationship/sexual satisfaction in part because touch helps to improve women's evaluations of their own bodies. Our results showed that body satisfaction was a significant, partial mediator and a valid path through which affectionate touch shapes relationship quality. Receiving affectionate touch could bolster relationship satisfaction and self-perceptions among women. Given the prevalence of body dissatisfaction amongst women, these results suggest that the underexplored associations between affectionate touch and body satisfaction may have significant impacts on a wide array of future empirical and applied research trajectories.

Validation of the Short Version (TLS-15) of the Triangular Love Scale (TLS-45) across 37 Languages.

Love is a phenomenon that occurs across the world and affects many aspects of human life, including the choice of, and process of bonding with, a romantic partner. Thus, developing a reliable and valid measure of love experiences is crucial. One of the most popular tools to quantify love is Sternberg's 45-item Triangular Love Scale (TLS-45), which measures three love components: intimacy, passion, and commitment. However, our literature review reveals that most studies (64%) use a broad variety of shortened versions of the TLS-45. Here, aiming to achieve scientific consensus and improve the reliability, comparability, and generalizability of results across studies, we developed a short version of the scale-the TLS-15-comprised of 15 items with 5-point, rather than 9-point, response scales. In Study 1 (N = 7,332), we re-analyzed secondary data from a large-scale multinational study that validated the original TLS-45 to establish whether the scale could be truncated. In Study 2 (N = 307), we provided evidence for the three-factor structure of the TLS-15 and its reliability. Study 3 (N = 413) confirmed convergent validity and test-retest stability of the TLS-15. Study 4 (N = 60,311) presented a large-scale validation across 37 linguistic versions of the TLS-15 on a cross-cultural sample spanning every continent of the globe. The overall results provide support for the reliability, validity, and cross-cultural invariance of the TLS-15, which can be used as a measure of love components-either separately or jointly as a three-factor measure.

Exploring Attitudes Toward "Sugar Relationships" Across 87 Countries: A Global Perspective on Exchanges of Resources for Sex and Companionship.

The current study investigates attitudes toward one form of sex for resources: the so-called sugar relationships, which often involve exchanges of resources for sex and/or companionship. The present study examined associations among attitudes toward sugar relationships and relevant variables (e.g., sex, sociosexuality, gender inequality, parasitic exposure) in 69,924 participants across 87 countries. Two self-report measures of Acceptance of Sugar Relationships (ASR) developed for younger companion providers (ASR-YWMS) and older resource providers (ASR-OMWS) were translated into 37 languages. We tested cross-sex and cross-linguistic construct equivalence, cross-cultural invariance in sex differences, and the importance of the hypothetical predictors of ASR. Both measures showed adequate psychometric properties in all languages (except the Persian version of ASR-YWMS). Results partially supported our hypotheses and were consistent with previous theoretical considerations and empirical evidence on human mating. For example, at the individual level, sociosexual orientation, traditional gender roles, and pathogen prevalence were significant predictors of both ASR-YWMS and ASR-OMWS. At the country level, gender inequality and parasite stress positively predicted the ASR-YWMS. However, being a woman negatively predicted the ASR-OMWS, but positively predicted the ASR-YWMS. At country-level, ingroup favoritism and parasite stress positively predicted the ASR-OMWS. Furthermore, significant cross-subregional differences were found in the openness to sugar relationships (both ASR-YWMS and ASR-OMWS scores) across subregions. Finally, significant differences were found between ASR-YWMS and ASR-OMWS when compared in each subregion. The ASR-YWMS was significantly higher than the ASR-OMWS in all subregions, except for Northern Africa and Western Asia.

Gender Issues in Physiotherapy in Quebec, Canada.

Purpose: This study examines gender differences in the physiotherapy (PT) profession in the province of Quebec regarding: (1) areas of practice; (2) roles associated with the advancement of the profession; (3) formal disciplinary complaints; and (4) interests and competency perceptions of PT students. Methods: We collected data from the Canadian Institute of Health Information, the Quebec Professional Order of Physiotherapy, Quebec university public Internet sites, and PT associations. We also surveyed PT students at the Université de Montréal. Results: The PT workforce in Quebec was 76.6% women. The presidents of the four main PT associations were men. In the five university programmes, the percentage of male and female physiotherapists in tenure track positions was 46% and 54%, respectively. There were more sanctioned complaints of sexual misconduct and not maintaining continuing education for male physiotherapists, while more women were sanctioned for problems with documentation and billing. Among students, men were more interested in becoming administrators, but neither men nor women had a strong interest in research. Conclusions: Male physiotherapists make up 23.4% of the PT workforce in Quebec but are more involved in leadership positions in the profession than women.

Objectif : examiner les différences de genre en physiothérapie au Québec à l'égard 1) des secteurs d'exercice, 2) des rôles associés à l'avancement de la profession, 3) des plaintes disciplinaires officielles et 4) des intérêts des étudiants en physiothérapie et de leurs perceptions à l'égard des compétences. Méthodologie : collecte de données auprès de l'Institut canadien d'information sur la santé, de l'Ordre professionnel de la physiothérapie du Québec, des sites Internet publics des universités québécoises et des associations de physiothérapie. Sondage auprès des étudiants en physiothérapie de l'Université de Montréal. Résultats : au Québec, la main-d'œuvre en physiothérapie était composée de 76,6 % de femmes. Ce sont des hommes qui présidaient les quatre principales associations de physiothérapie. Dans les cinq programmes universitaires, le pourcentage de physiothérapeutes de sexe masculin et féminin qui occupaient des postes menant à la permanence s'élevait à 46 % et à 54 %, respectivement. On dénombrait plus de plaintes sanctionnées d'inconduite sexuelle et de non-respect de la formation continue chez les physiothérapeutes de sexe masculin, tandis que plus de femmes étaient sanctionnées pour des problèmes de tenue de dossier et de facturation. Chez les étudiants, les hommes étaient plus intéressés à devenir administrateurs, mais ni les hommes ni les femmes ne témoignaient d'un intérêt marqué envers la recherche. Conclusions : les physiothérapeutes de sexe masculin représentent 23.4% de la main-d'œuvre en physiothérapie au Québec, mais occupent plus de postes de direction dans la profession que les femmes.

A Slim Majority: The Influence of Sex Ratio on Women's Body Dissatisfaction and Weight Loss Motivations.

The current investigation examined whether women's perceptions of the sex ratio (ratio of women to men) in the local population influence their body dissatisfaction and weight loss motivations. A higher ratio of women to men in a given population signifies a relative abundance of same-sex mating competitors, intensifying female intrasexual competition. Five studies (N = 1,776) tested the hypotheses that women's perceptions of a female-skewed sex ratio would correspond to increased feelings of intrasexual competitiveness and perceptions of unfavorable mating prospects, which would, in turn, be associated with heightened body dissatisfaction and weight loss motivations. Among university and community women (Studies 1and 2), perceptions of a female-skewed sex ratio corresponded to greater intrasexual competitiveness, increased body dissatisfaction, and increased dieting inclinations. Among single women, assessments of a female-skewed sex ratio corresponded to perceptions of unfavorable mating prospects, increased romantic pressure to alter their appearance, and higher body dissatisfaction (Study 3). Studies 4 and 5 experimentally manipulated perceived sex ratio. Women in the female-skewed condition felt less satisfied with their weights and shapes, but only if they believed the manipulation (Study 4). In Study 5, using a within-subjects design, women who evaluated a male-skewed (vs. female-skewed) dating profile array subsequently desired to lose less weight. Findings suggest women's perceptions of their social environments may contribute to body image and dieting motivations.

The U.S. Body Project I: Inspirations and Lessons Learned.

The U.S. Body Project I examined predictors and prevalence of body image concerns among 11,620 adults recruited via Mechanical Turk. Researchers were invited to propose hypotheses or conduct secondary data analysis on the anonymized dataset. This resulted in 11 papers for this special issue. The first four papers examined the demographic predictors and prevalence of (1) body satisfaction, (2) objectification and tripartite model constructs, (3) sexuality-related body image concerns, and (4) face image satisfaction. The next four papers tested different structural equation models linking objectification and tripartite constructs to outcomes among women (5) and men (6) varying in body mass, and across racial (7) and sexual orientation (8) groups. We then tested measurement invariance of the scales (9) and introduced an abbreviated measure (10), and applied machine learning to examine associations among variables (11). Here we reflect on our personal and academic journeys leading to this project, and lessons learned.

Measured weight loss as a precursor to cancer diagnosis: retrospective cohort analysis of 43 302 primary care patients.

BACKGROUND: Unexpected weight loss is a presenting feature of cancer in primary care. Data from primary care are lacking to quantify how much weight loss over what period should trigger further investigation for cancer. This research aimed to quantify cancer diagnosis rates associated with measured weight change in people attending primary care. METHODS: Retrospective cohort study of primary care electronic health records data linked to the Surveillance, Epidemiology, and End Results cancer registry (Integrated healthcare delivery system in Washington State, United States). Multivariable Cox regression incorporating time varying covariates using splines to model non-linear associations (age, percentage weight change, and weight change interval). Fifty thousand randomly selected patients aged 40 years and over followed for up to 9 years (1 January 2006 to 31 December 2014). Outcome measures are hazard ratios (95% confidence intervals) to quantify the association between percentage weight change and cancer diagnosis for all cancers combined, individual cancer sites and stages; percentage risk of cancer diagnosis within 6 months of the end of each weight change episode; and the positive predictive value for cancer diagnosis. RESULTS: There were 43 302 included in the analysis after exclusions. Over 287 858 patient-years of follow-up, including 24 272 (56.1%) females, 23 980 (55.4%) aged 40 to 59 years, 15 113 (34.9%) 60 to 79 years, and 4209 (9.7%) aged 80 years and over. Adjusted hazard ratios (95% confidence interval) for cancer diagnosis in a 60 years old ranged from 1.04 (1.02 to 1.05, P < 0.001) for 1% weight loss to 1.44 (1.23 to 1.68, P < 0.001) for 10%. An independent linear association was observed between percentage weight loss and increasing cancer risk. The absolute risk of cancer diagnosis increased with increasing age (up to 85 years) and as the weight change measurement interval decreased (<1 year). The positive predictive value for a cancer diagnosis within 1 year of ≥5% measured weight loss in a 60 to 69 years old was 3.41% (1.57% to 6.37%) in men and 3.47% (1.68% to 6.29%) in women. The risk of cancer diagnosis was significantly increased for pancreatic, myeloma, gastro-oesophageal, colorectal, breast, stage II and IV cancers. CONCLUSIONS: Weight loss is a sign of undiagnosed cancer regardless of the interval over which it occurs. Guidelines should resist giving an arbitrary cut-off for the interval of weight loss and focus on the percentage of weight loss and the patient's age. Future studies should focus on the association between diagnostic evaluation of weight change and risk of cancer mortality.

Measurement invariance of body image measures by age, gender, sexual orientation, race, weight status, and age: The U.S. Body Project I.

Despite growing interest in comparing body image experiences across diverse groups, limited work has examined whether body image measures operate similarly across different populations, raising important questions about the appropriateness of comparing scale means across demographic groups. This study employed measurement invariance testing to evaluate whether such comparisons are appropriate with existing body image measures. Specifically, multi-group confirmatory factor analysis was conducted using a community sample of 11,620 men and women to test increasing levels of invariance (configural, metric, scalar) across five key demographic variables (age group, gender, sexual orientation, race, weight status) for five commonly used body image measures (the Sociocultural Attitudes Towards Appearance Questionnaire-4, the Body Surveillance subscale of the Objectified Body Consciousness Scale, the Appearance Evaluation and Overweight Preoccupation subscales of the Multidimensional Body-Self Relations Questionnaire, and the Body Image Quality of Life Inventory). Results provided evidence of scalar (i.e., strong) invariance for all five measures across age, gender, sexual orientation, race, and weight status groups, indicating that the latent factors captured by these measures have the same meaning across demographic groups. Findings therefore support the comparison of scale/subscale means across multiple demographic groups for these body image measures.

Demographic and sociocultural predictors of sexuality-related body image and sexual frequency: The U.S. Body Project I.

Body image is a critical component of an individual's sexual experiences. This makes it critical to identify demographic and sociocultural correlates of sexuality-related body image: the subjective feelings, cognitions, and evaluations related to one's body in the context of sexual experience. We examined how sexuality-related body image differed by gender, sexual orientation, race, age, and BMI. Four items assessing sexuality-related body image were completed by 11,620 U.S. adults: self-perceived sex appeal of their body, nude appearance satisfaction, and the extent to which they believed that body image positively or negatively affected their sexual enjoyment and feelings of sexual acceptability as a partner. Men reported slightly less nude appearance dissatisfaction and fewer negative effects of body image on sexual enjoyment and sexual acceptability than women, but did not differ in reported sex appeal. Poorer sexuality-related body image was reported by people with higher BMIs, not in relationships, who had sex less frequently, among White compared to Black women and men, and among gay compared to heterosexual men. Data also revealed a subgroup of respondents who reported that their body image had a positive impact on their sex lives. The findings highlight a need for interventions addressing sexuality-related body image.

Pathways from sociocultural and objectification constructs to body satisfaction among men: The U.S. Body Project I.

According to the tripartite influence model, body dissatisfaction is shaped by internalizing cultural appearance ideals stemming from appearance-related family, peer, and media pressures. This model was developed for women, but emerging evidence points to its relevance for men's body image. This study advanced this budding research by (a) integrating muscular-ideal internalization alongside lean-ideal internalization and body surveillance into the model, (b) examining two positive dimensions of body image as outcomes (body image quality of life and appearance evaluation), and (c) testing this model in national online sample of 5293 men. Structural equation modeling supported the model. Family, peer, and media pressures related to higher lean-ideal internalization, which related to higher body surveillance and poorer body image outcomes. Peer and media pressures related to higher muscular-ideal internalization, which related to higher body surveillance but more adaptive body image outcomes. We further examined whether model variables and paths differed based on men's body mass index (BMI). Men with higher BMIs evidenced a stronger path between body surveillance and body image outcomes. These findings highlight the usefulness of sociocultural models for understanding men's body image experiences.

Sexual orientation differences in pathways from sociocultural and objectification constructs to body satisfaction: The U.S. Body Project I.

Objectification theory and the tripartite influence model provide useful frameworks for understanding the body image experiences of men and women. However, there is little systematic investigation of how sexual orientation moderates the links between these constructs and body image satisfaction. It has been hypothesized, for example, that the associations of surveillance (i.e., monitoring of one's appearance due to objectification by others) would be strongest for groups targeted by the male gaze (e.g., gay men, lesbian women, and bisexual men and women). Here we proposed an integrated sociocultural model and examined these pathways in multigroup structural equation models in a national sample of heterosexual, bisexual, and lesbian women (ns = 5395; 598; 213, respectively), and heterosexual, bisexual, and gay men (4869; 194; and 194, respectively) aged 18-65 years. Sexual orientation moderated some of these pathways. The most consistent pattern was that appearance pressures were internalized to a greater extent among bisexual participants. The pathways to poorer body image were generally similar among heterosexual and gay/lesbian men and women. These findings highlight the importance of examining sexual orientation-specific influences on body image across diverse groups, as well as the commonalities in the experiences of men and women across sexual orientations.

Racial identity differences in pathways from sociocultural and objectification constructs to body satisfaction: The U.S. Body Project I.

Racial minority men and women face a wide variety of appearance-related pressures, including ones connected to their cultural backgrounds and phenotypic features associated with their identity. These body image concerns exist within a larger context, wherein racial minorities face pressures from multiple cultures or subcultures simultaneously to achieve unrealistic appearance ideals. However, limited research has investigated racial differences in the relationships between theorized sociocultural risk factors and body image in large samples. This study tests pathways from an integrated sociocultural model drawing on objectification theory and the tripartite influence model to three key body image outcomes: appearance evaluation, body image quality of life, and face image satisfaction. These pathways were tested using multigroup structural equation modeling in a national sample of White, Black, Hispanic, and Asian men and women (ns = 205-4797 per group). Although many hypothesized associations were similar in strength across groups, race moderated some of the pathways between sociocultural pressures (media, peer, family), internalization of appearance ideals (thin-ideal, muscular/athletic), appearance surveillance, and body image outcomes. Findings support the likely role of both shared and specific risk factors for body image outcomes, suggesting avenues for tailoring adapted interventions in order to target culturally-salient risk factors.

Pathways from sociocultural and objectification constructs to body satisfaction among women: The U.S. Body Project I.

Objectification theory proposes that widespread sexualization causes women to engage in surveillance of their appearance. We integrated this concept into a model with constructs from the tripartite influence model, which proposes that body dissatisfaction is a result of internalizing cultural notions of thin ideal beauty that stem from family, peer, and media appearance-related pressures. We tested this model with an online sample of 6327 adult women. Specifically, we tested whether these pressures predicted increased thin-ideal and muscular-ideal internalization, leading to greater body surveillance, and in turn lower appearance evaluation and body image quality of life. Structural equation modeling supported many aspects of the model. Family, peer, and media pressures related to higher thin-ideal internalization, which related to higher body surveillance and lower appearance evaluation. Peer and media pressures related to higher muscular-ideal internalization, which related to lower appearance evaluation. However, muscular-ideal internalization was not related to body image quality of life. An indirect relationship emerged between thin-ideal internalization and body image outcomes via body surveillance. Body mass index (BMI) moderated several of these model paths. Findings highlight the value of this integrated sociocultural model, and of BMI as an important moderating factor when examining objectification and tripartite influence models.

Demographic and sociocultural predictors of face image satisfaction: The U.S. Body Project I.

Despite substantial literature surrounding how people process and perceive faces, there is very little research investigating how people evaluate their own faces. We examined how gender, body mass, race, age, and sexual orientation were linked to people's satisfaction with the appearance of their eyes, nose, facial shape, and face overall among 11,620 adults recruited via Mechanical Turk. Most people mostly or definitely agreed they were happy with their facial appearance. There were notable racial differences, with Asian participants tending to report greater dissatisfaction. For example, only 66% of Asian women and 60% of Asian men mostly or definitely agreed that they were happy with the appearance of their eyes, which was lower than other racial groups. BMI and age were not strongly associated with face satisfaction. Sexual minority men were less satisfied than heterosexual men. About one in four gay and bisexual men, compared to only one in seven heterosexual men, reported dissatisfaction with their overall facial appearance. Men and women with poorer face image engaged in more appearance surveillance, more strongly internalized the thin-ideal, and perceived stronger sociocultural pressures from peers, parents, and media. The current study highlights important sociocultural and demographic factors tied to poorer face image.

Examining the utility of nonlinear machine learning approaches versus linear regression for predicting body image outcomes: The U.S. Body Project I.

Most body image studies assess only linear relations between predictors and outcome variables, relying on techniques such as multiple Linear Regression. These predictor variables are often validated multi-item measures that aggregate individual items into a single scale. The advent of machine learning has made it possible to apply Nonlinear Regression algorithms-such as Random Forest and Deep Neural Networks-to identify potentially complex linear and nonlinear connections between a multitude of predictors (e.g., all individual items from a scale) and outcome (output) variables. Using a national dataset, we tested the extent to which these techniques allowed us to explain a greater share of the variance in body-image outcomes (adjusted R2) than possible with Linear Regression. We examined how well the connections between body dissatisfaction and dieting behavior could be predicted from demographic factors and measures derived from objectification theory and the tripartite-influence model. In this particular case, although Random Forest analyses sometimes provided greater predictive power than Linear Regression models, the advantages were small. More generally, however, this paper demonstrates how body image researchers might harness the power of machine learning techniques to identify previously undiscovered relations among body image variables.

Demographic predictors of body image satisfaction: The U.S. Body Project I.

We examined how gender, body mass, race, age, and sexual orientation were linked to appearance evaluation, overweight preoccupation, and body image-related quality of life among 11,620 adults recruited via Mechanical Turk. Men were less likely than women to report low appearance evaluation, high overweight preoccupation, negative effects of body image on their quality of life, being on a weight-loss diet, and trying to lose weight with crash diets/fasting. Racial differences were generally small, but greater appearance evaluation was reported by Black men versus other groups and Black women versus White women. Across all measures, gay and bisexual men reported poorer body image than heterosexual men, with only small effect sizes observed for sexual orientation differences among women. Body mass, but not age, was strongly associated with body image. The prevalence of poor body image highlights the need for interventions. On the positive side, half of men and women reported high appearance evaluation. Examination of this group could identify factors promoting positive body image.

An abbreviated 10-item, two-factor version of the Body Image Quality of Life Inventory (BIQLI-10): The U.S. Body Project I.

The objective of this study was to re-examine the factor structure of the Body Image Quality of Life Inventory (BIQLI), a measure that quantifies perceived effects of one's body image on various aspects of psychosocial functioning. Data on the 19-item BIQLI from a community sample of 11,620 U.S. men and women were split into cross-validation samples and underwent exploratory and confirmatory factor analysis. An abbreviated 10-item, two-factor version of the BIQLI (BIQLI-10) was identified. The BIQLI-10 measures Social Relations & Psychological Well-Being with one subscale and Appearance & Body Management Activities with the other. Internal consistency was high for each subscale. The BIQLI-10 largely retained the convergent validity of the original 19-item BIQLI, as evidenced by nearly identical correlations with appearance evaluation, overweight preoccupation, body surveillance, appearance pressures, and appearance ideal internalization. Results also supported strong measurement invariance for the BIQLI-10 by age group, gender, sexual orientation, racial group, and weight status. Findings from this study suggest researchers may use this abbreviated version to increase nuance in the measurement of body image quality of life and reduce participant burden without compromising the psychometric integrity of the BIQLI. Further, results support the comparison of BIQLI-10 subscale scores across diverse groups.

Demographic predictors of objectification theory and tripartite influence model constructs: The U.S. Body Project I.

We examined how demographic factors (gender, sexual orientation, racial group, age, body mass) were linked to measures of sociocultural appearance concerns derived from objectification theory and the tripartite influence model (McKinley & Hyde, 1996; Schaefer et al., 2015) among 11,620 adults. Men were less likely than women to report high body surveillance, thin-ideal internalization, appearance-related media pressures, and family pressures; did not differ in peer pressures; and reported greater muscle/athletic internalization. Both men and women expressed greater desire for their bodies to look "very lean" than to look "very thin". Compared to gay men, heterosexual men reported lower body surveillance, thin-ideal internalization, peer pressures, and media pressures. Black women reported lower thin-ideal internalization than White, Hispanic, and Asian women, whereas Asian women reported greater family pressures. Being younger and having higher BMIs were associated with greater sociocultural appearance concerns across most measures. The variation in prevalence of sociocultural appearance concerns across these demographic groups highlights the need for interventions.
