RESUMO

Past findings on the association between negative body image and sexual health behaviors have been mixed and mostly derived from Western samples. The aim of the current study was to examine associations between indices of negative body image and sexual health practices that reduce the risk of disease transmission in emerging adults, and whether these associations are moderated by gender. Using an online survey, a convenience sample of 584 Malaysian adults aged 18-30 years (230 men, 354 women) completed measures of satisfaction with overall appearance, body size dissatisfaction, weight satisfaction, height satisfaction, and genital image evaluation. They also reported if they ever had partnered sex, condomless sex, and been screened for human immunodeficiency virus (HIV), as well as their lifetime number of penetrative sex partners. Hierarchical logistic and ordinal regression analyses indicated that more positive genital image evaluation, but not the other body image indices, was significantly associated with having had partnered sex and fewer lifetime penetrative sex partners. None of the body image indices were significantly associated with condomless sex. All associations were consistent across men and women. For HIV testing, a significant interaction between genital image evaluation and gender emerged. However, this was reduced to non-significance after controlling for the number of penetrative sex partners. Overall, our findings underline the importance of promoting improved genital image in interventions aimed at increasing positive sexual health behaviors.

RESUMO

The Teruel Orthorexia Scale (TOS) is a 17-item instrument designed to assess distinct facets of Orthorexia Nervosa (ON) and Healthy Orthorexia (HO). While a bidimensional model of TOS scores has been supported in diverse national and linguistic groups, the psychometric properties of the TOS have not been previously assessed in Greek-speaking populations. To rectify this, we assessed the psychometric properties of a novel Greek translation of the TOS in a sample of adults from Cyprus. A total of 1248 respondents (710 women, 538 men) completed the Greek TOS, as well as previously validated measures of perfectionism, obsessive-compulsive symptomatology, eating restriction, negative affect, and appearance evaluation. Our results showed that a bidimensional model of the TOS had less-than-adequate fit when modelled using both confirmatory factor analysis and exploratory structural equation modeling (ESEM). Conversely, both exploratory factor analysis and ESEM supported extraction of a 3-factor model consisting of a HO facet and separate components of emotional orthorexia and cognitive-social orthorexia. This 3-factor model showed a lack of measurement bias (measurement invariance across gender identity and lack of differential item functioning as function of age and body mass index), but there were differences in latent factor means as function of respondent age and body mass index. The 3-factor model showed adequate evidence of construct validity, with the latent emotional orthorexia and cognitive-social orthorexia facets showing significant and moderate associations with the additional constructs measured in the survey. Broadly speaking, these findings support the psychometric properties of a 3-factor model of the Greek TOS, but also suggest that the bidimensional model of the TOS may not have universal applicability. We encourage further assessments of factorial validity in other national and linguistic contexts.

RESUMO

Intuitive eating has been found to protect against disordered eating and preserve well-being. Yet, there are methodological (length), conceptual (inconsideration of medical, value-based, and access-related reasons for food consumption), and psychometric (item wording) concerns with its most common measure, the Intuitive Eating Scale-2 (IES-2). To address these concerns, we developed the IES-3 and investigated its psychometric properties with U.S. community adults. Across three online studies, we evaluated the IES-3's factorial validity using exploratory factor analysis (EFA; Study 1; N = 957; Mage = 36.30), as well as confirmatory factor analysis (CFA), exploratory structural equation modeling (ESEM), bifactor-CFA, and bifactor-ESEM (Study 2; N = 1152; Mage = 40.95), and cross-validated the optimal model (Study 3; N = 884; Mage = 38.54). We examined measurement invariance across samples and time, differential item functioning (age, body mass index [BMI], gender), composite reliability, and validity. Study 1 revealed a 12-item, 4-factor structure (unconditional permission to eat, eating for physical reasons, reliance on hunger and satiety cues, body-food choice congruence). In Study 2, a bifactor-ESEM model with a global intuitive eating factor and four specific factors best fit the data, which was temporally stable across three weeks. This model also had good fit in Study 3 and, across Studies 2 and 3, and was fully invariant and lacked measurement bias in terms of age, gender, and BMI. Associations between latent IES-3 factors and age, gender, and BMI were invariant across Studies 2 and 3. Composite reliability and validity (relationships with disordered eating, embodiment, body image, well-being, and distress; negligible relationship with impression management) of the retained model were also supported. The 12-item IES-3 demonstrates strong psychometric properties in U.S. community adults. Research is now needed using the IES-3 in other cultural contexts and social identity groups.

RESUMO

INTRODUCTION: Dysmorphic concerns refer to excessive preoccupations with one's physical characteristics. There is a need to better understand the factors associated with these experiences, especially in young adult women. Given emergent research suggesting a link between the use of Instagram, dysmorphic concerns, and appearance pressures, we tested a mediation model in which appearance-based rejection sensitivity mediated the relationship between Instagram addiction and dysmorphic concerns. METHODS: In this cross-sectional study, 300 young adult women from Romania with mean age of 22.19 years (SD = 2.07) and who possessed an Instagram account were asked to complete an online survey consisting of measures of dysmorphic concerns, Instagram addiction, and appearance-based rejection sensitivity. RESULTS: Correlational analyses revealed that all three variables were positively and moderately inter-correlated. Mediation analysis supported the hypothesis that appearance-based rejection sensitivity mediates the relationship between Instagram addiction and dysmorphic concerns. CONCLUSIONS: Implications of this study are discussed in terms of the urgency of prevention and intervention strategies, especially given the link between dysmorphic concerns and more extreme manifestations of severity, such as body dysmorphic disorder.

RESUMO

Understandings of paternal postnatal depression (PND) in fathers from the United Kingdom (UK) have received limited attention, particularly in view of changing dynamics of contemporary parenthood. To rectify this, eight UK fathers with PND took part in one-to-one interviews, with Interpretative Phenomenological Analysis used to understand their lived experiences. Our findings demonstrate that UK fathers with PND experienced extremely distressing emotions, including anger and misery, after their babies are born. Their working practices were highly relevant to their fatherhood, with working considered a key responsibility and a source of stress, but also a "legitimate" escape from the home. Fathers' relationships with their partners were experienced as less intimate and conflicted. Fathers often hid their feelings to protect their partners, but also reported their partners as being aware of their challenging and difficult emotions. Healthcare providers should be professionally curious about fathers' mental health and consider the assistance of mothers in identifying cases of paternal PND.

RESUMO

Emerging research has suggested that appearance-related factors, such as greater appearance orientation, are associated with dating anxiety in emerging adults, but much more could be done to understand mechanistic pathways and potential buffers. Here, we tested a moderated mediation model in which appearance-based rejection sensitivity and social physique anxiety were explored as mediators, and self-compassion was explored as a moderator, of the relationship between appearance orientation and dating anxiety. A total of 501 heterosexual emerging adults (248 women, 253 men) from the UK completed instruments measuring the aforementioned constructs. Relationships among all variables were largely similar across women and men, with only the association between social physique anxiety and appearance-based rejection sensitivity being significantly stronger in women. Mediation analysis in the total sample indicated that both social physique anxiety and appearance-based rejection anxiety were significant mediators. Additionally, we confirmed a serial mediation involving appearance orientation → appearance-based rejection sensitivity → social physique anxiety → dating anxiety. Conversely, self-compassion did not moderate the effects of either social physique anxiety or appearance-based rejection sensitivity on dating anxiety, although greater self-compassion was moderately associated lower dating anxiety. We suggest ways in which existing interventions aimed at reducing dating anxiety could be combined with body image interventions to reduce dating anxiety in heterosocial contexts.

RESUMO

Exposure to nature is associated with improved psychological well-being and positive body image. Here, we examined whether everyday exposure to natural environments is associated with state body image outcomes (and, for comparative reasons, state happiness) using an experience sampling method. One-hundred-and-seven participants completed a 30-day experience sampling phase in which they reported their state body image (body weight, body shape, and physical appearance satisfaction), state happiness, and features of the surrounding environment (total = 6,025 responses) at three random time-points each day. Results indicated that being outdoors was associated with significantly higher state body image on all three indicators, but effect sizes were lower compared to effects on state happiness. Specific environment type was also important, with blue-spaces and wood- and grasslands, respectively, having stronger effects than other environments. These results provide evidence that everyday exposure to natural environments is associated with more positive state body image and greater happiness.

RESUMO

Recent studies have highlighted high levels of emotional eating during the coronavirus (COVID-19) pandemic, but have not satisfactorily explained these changing eating patterns. Here, we tested one potential explanatory model broadly based on a biosocial model of emotional eating. Specifically, we examined the extent to which negative emotional reactivity was associated with emotional eating, as well as the mediating role of fear of COVID-19. A total of 474 women from Romania were asked to complete measures of emotional eating, negative emotional reactivity, and fear of COVID-19. Mediation analysis showed that higher negative emotional reactivity was significantly and directly associated with greater emotional eating. This direct relationship was also mediated by fear of COVID-19. These results highlight one possible route through which the ongoing COVID-19 pandemic may have resulted in elevated rates of emotional eating, though further research is needed.

RESUMO

PURPOSE: Previous studies examining the appropriateness of the 4-factor model of intuitive eating scale-2 (IES-2) scores have returned equivocal results, which may reflect methodological limitations in the way IES-2 scores are modelled. Here, we applied a bifactor-exploratory structural equation modelling (B-ESEM) framework to better understand IES-2 multidimensionality. METHODS: A total of 603 participants from the United States completed the IES-2, alongside measures of body appreciation, body acceptance from others, and self-esteem. Our analyses compared the fit of various hypothesised models of IES-2 scores. RESULTS: Models of IES-2 scores based on confirmatory factor analysis (CFA) uniformly showed poor fit. ESEM models showed superior fit to CFA representations and a B-ESEM model showed improved fit over higher-order CFA and B-CFA representations of IES-2 scores. The optimal model was a B-ESEM model that accounted for, through correlated uniqueness (CU), the methodological artefact introduced by negatively-worded IES-2 items. This B-ESEM-CU model was fully invariant across gender and showed adequate construct validity. CONCLUSION: The B-ESEM-CU framework appears well-suited to understand the multidimensionality of IES-2 scores. A model of IES-2 scores that yields a reliable latent indicator of global intuitive eating while allowing for simultaneous consideration of additional specific factors will likely provide more accurate accounting of the nature and outcomes of intuitive eating. LEVEL OF EVIDENCE: Level III, cohort study.

RESUMO

The construct of intuitive eating is most often measured using the 23-item Intuitive Eating Scale-2 (IES-2), but previous studies have typically relied solely on confirmatory factor analysis (CFA) to understand IES-2 dimensionality. In contrast, a bifactor exploratory structural equation modelling (B-ESEM) framework offers a more realistic account of IES-2 multidimensionality. Here, we assessed the psychometric properties of a novel Italian translation using a combination of exploratory factor analysis and B-ESEM. A total of 950 adults completed the IES-2 alongside measures of positive body image, disordered eating, and psychological well-being. Results indicated that a 4-factor B-ESEM model had adequate fit to the data and that fit was improved when the correlated uniqueness of seven negatively worded IES-2 items was accounted for. This model of IES-2 scores showed adequate internal consistency and good test-retest reliability up to three weeks. Evidence of construct validity was good in terms of a global IES-2 factor, and broadly supported in terms of its specific-factors. These results highlight the utility of a B-ESEM framework for understanding the dimensionality of IES-2 scores and may help scholars better understand the extent to which the IES-2 adequately operationalises the construct of intuitive eating.

RESUMO

The ongoing coronavirus (COVID-19) pandemic and attendant lockdown mandates may have detrimental effects on body image outcomes, which in turn highlights the importance of identifying protective factors. Here, we examined associations between COVID-19-related stress and body image disturbance, as well as the potential mediating and moderating role of self-compassion. During the third lockdown in the United Kingdom, we asked an online sample of adults (N = 600) to complete measures of COVID-19-related stress, body image disturbance, and self-compassion. Mediation analysis showed that higher COVID-19-related stress was significantly associated with greater body image disturbance, and that this relationship was mediated by self-compassion. In contrast, self-compassion did not significantly moderate the effects of stress on body image disturbance. These results suggest that promoting greater self-compassion may be a viable means of mitigating adverse outcomes from the COVID-19 pandemic on body image disturbance.

RESUMO

The stress and anxiety caused by the coronavirus (COVID-19) pandemic presents a serious threat to psychological well-being in populations worldwide and may also extend to body image outcomes. To test this hypothesis, we conducted a preliminary study in which an online sample of adults from the United Kingdom (N = 506, age M = 34.25 years) were asked to complete measures of perceived stress, stressful life events, trait anxiety, COVID-19-related stress and anxiety, and negative body image (body dissatisfaction and drive for thinness in women, body fat and muscularity dissatisfaction in men). The results of hierarchical regressions indicated that COVID-19-related stress and anxiety explained significant incremental variance in body image outcomes (Adj. ΔR 2 = .02 to .10), over-and-above demographics (age and body mass index) and perceived stress, trait anxiety, and stressful life events. These findings suggest that COVID-19-related stress and anxiety may shape body image outcomes under conditions of physical and social distancing.

RESUMO

The coronavirus (COVID-19) pandemic and attendant lockdown measures present serious threats to emotional well-being worldwide. Here, we examined the extent to which being outdoors (vs. indoors), the experience of loneliness, and screen-time are associated with emotional well-being during the COVID-19 pandemic using an experiencing sampling method. In April 2020, Austrian adults (N = 286, age M = 31.0 years) completed a 21-day experience sampling phase in which they reported their emotional well-being (i.e., happiness), whether they were indoors or outdoors, and loneliness at three random time-points each day, as well as their daily screen-time. Results indicated that being outdoors was associated with higher emotional well-being, whereas greater loneliness and greater daily screen-time were associated with poorer well-being. Additionally, the impact of loneliness on well-being was weaker when participants were outdoors than indoors. These results have health policy implications for the promotion of population well-being during pandemics.

RESUMO

INTRODUCTION: Physical activity is likely to be associated with sexual activity. However, to date, there is no literature on the relationship between overweight/obesity and sexual activity outcomes. AIM: Thus, the present study assessed the associations among physical activity, sedentary behavior, and weight status with sexual activity and number of previous sexual partners in a representative sample of U.S. adults. METHODS: Data on leisure time physical activity, total sitting time, weight status, sexual behavior outcomes, and other characteristics were extracted from the National Health and Nutrition Study cycle 2007 to 2016. Logistic regression models were used to evaluate associations among body mass index, leisure time physical activity, and total sitting time with past-year sexual activity and number of sexual partners. MAIN OUTCOME MEASURE: Self reported frequency of past-year sexual activity and number of sex partners in the past year. RESULTS: In a sample of 7,049 men (mean age: 38.3 ± 0.3 years) and 7,005 women (mean age: 38.7 ± 0.2 years) being overweight was associated with higher odds of frequent sexual activity (OR = 1.5; 95% CI = 1.2-1.7) among men, but lower odds among women (OR = 0.8; 95% CI = 0.6-0.9). Sufficient physical activity was associated with higher odds of frequent sexual activity among both men (OR = 1.3; 95% CI = 1.1-1.5) and women (OR = 1.2; 95% CI = 1.0-1.4). In those living alone, being obese was associated with lower odds of having at least 1 sexual partner for men (OR = 0.7; 95% CI = 0.5-0.9) and women (OR = 0.6; 95% CI = 0.4-0.8). Being sufficiently physically active was associated with higher odds of having at least 1 sexual partner only in men (OR = 1.6; 95% CI = 1.2-2.2). CLINICAL IMPLICATIONS: Healthcare professionals need to be made aware of these results, as they could be used to plan tailored interventions. STRENGTHS & LIMITATIONS: Strengths include the large, representative sample of U.S. adults and objective measures of anthropometry. Limitations include the cross-sectional design of the study and that all variables on sexual history were self-reported. CONCLUSION: The present study identifies novel modifiable behavioral and biological antecedents of sexuality outcomes. Grabovac I, Cao C, Haider S, et al.

RESUMO

The Caregiver Eating Messages Scale (CEMS) was developed to assess perceived restrictive or critical caregiver messages in relation to food intake and pressure to eat, whereas the Intuitive Eating Scale-2 (IES-2) measures one's tendency to follow internal cues of hunger and satiety when making eating-related decisions. Both scales are useful in the arsenal of eating behaviour scholars. Here, we developed Brazilian Portuguese translations of both scales and assessed their psychometric properties in Brazilian adults. A total of 288 participants (men = 52.8%) completed the CEMS, IES-2, Body Appreciation Scale (BAS), and a demographic questionnaire. The results of confirmatory factor analysis indicated that the factor structure of both scales had adequate fit following the elimination of items and addition of covariances. Evidence of adequate factorial, convergent and discriminant validity, as well as reliability was identified. Furthermore, correlations of CEMS and IES-2 with BAS scores and body mass index were obtained. Both instruments' models were found to be invariant across sex, with men having significantly higher scores on three subscales of the IES-2 only. These results provide evidence for the psychometric properties of the CEMS and IES-2 in Brazilian Portuguese-speaking adults.Level of Evidence: V, cross-sectional descriptive study.

RESUMO

Background: Postnatal depression affects between 6 and 13% of new parents, but only a small proportion of individuals who meet diagnostic criteria receive optimal treatment. One reason for this is poor mental health literacy of postnatal depression.Aims: Studies have examined mental health literacy of maternal postnatal depression, but there are no similar studies of paternal postnatal depression, which we sought to rectify.Methods: A sample of 406 British adults was presented with vignettes describing cases of either maternal or paternal postnatal depression. Based on the vignettes, participants were asked to report if they thought anything was wrong with the targets and, if so, to describe what they thought was wrong. Participants also rated the targets on a range of attitudinal dimensions.Results: Participants were more likely to indicate that something was wrong when the target was female (97.0%) compared to male (75.9%). Of those who believed something was wrong, 90.1% of participants correctly described the female target as experiencing postnatal depression, but only 46.3% did so for the male target. Participants also held more positive attitudes toward the female target than the male target.Conclusions: There is a gender binary in symptom recognition of postnatal depression, which highlights the need for greater awareness of paternal postnatal depression.

RESUMO

While studies have documented robust relationships between body image and sexual health outcomes, few studies have looked beyond sexual functioning in women. Here, we hypothesized that more positive body image would be associated with greater sexual liberalism and more positive attitudes toward unconventional sexual practices. An online sample of 151 women and 164 men from the U.S. completed measures of sexual liberalism, attitudes toward unconventional sexual practices, and indices of positive body image (i.e., body appreciation, body acceptance by others, body image flexibility, and body pride), and provided their demographic details. Regression analyses indicated that, once the effects of sexual orientation, relationship status, age, and body mass index had been accounted for, higher body appreciation was significantly associated with greater sexual liberalism in women and men. Furthermore, higher body appreciation and body image flexibility were significantly associated with more positive attitudes toward unconventional sexual practices in women and men. These results may have implications for scholars working from a sex-positive perspective, particularly in terms of understanding the role body image plays in sexual attitudes and behaviors.

RESUMO

A large literature proposes that preferences for exaggerated sex typicality in human faces (masculinity/femininity) reflect a long evolutionary history of sexual and social selection. This proposal implies that dimorphism was important to judgments of attractiveness and personality in ancestral environments. It is difficult to evaluate, however, because most available data come from large-scale, industrialized, urban populations. Here, we report the results for 12 populations with very diverse levels of economic development. Surprisingly, preferences for exaggerated sex-specific traits are only found in the novel, highly developed environments. Similarly, perceptions that masculine males look aggressive increase strongly with development and, specifically, urbanization. These data challenge the hypothesis that facial dimorphism was an important ancestral signal of heritable mate value. One possibility is that highly developed environments provide novel opportunities to discern relationships between facial traits and behavior by exposing individuals to large numbers of unfamiliar faces, revealing patterns too subtle to detect with smaller samples.

RESUMO

OBJECTIVE: The purpose of this investigation was to examine change in risk for eating disorders in higher education students sojourning in the United Kingdom (UK), as well as associations between such risk and experiences in the host culture. METHOD: Participants were 98 female students from Malaysia, who completed a measure of risk factors for eating disorder symptomatology (the Eating Disorder Inventory-3 subscales of drive for thinness, body dissatisfaction, and bulimia symptoms) at two time points: two months prior to beginning their sojourn in the UK (Time 1) and four months after the sojourn began (Time 2). At Time 2, participants also completed measures of sociocultural adjustment, cultural distance between home and host cultures, and perceived discrimination in the host culture. RESULTS: Analyses indicated that, compared to scores at Time 1, participants had significantly higher drive for thinness (d = 0.64), body dissatisfaction (d = 0.54), and bulimia symptoms (d = 0.29) at Time 2. Poorer sociocultural adjustment and greater perceived discrimination significantly predicted greater risk of eating disorders at Time 2. DISCUSSION: The stress associated with culture change may place sojourning students at risk for disordered eating. Further research is needed to determine the extent to which this risk is related to culture-change specifically, as opposed to a general set of factors associated with transition-related psychopathology more broadly. © 2016 Wiley Periodicals, Inc.

RESUMO

Researchers, practitioners, and policy-makers are having to deal with the negative impact of body image concerns in populations globally. One cost-effective way of promoting healthier body image outcomes is through exposure to natural environments. A growing body of research has shown that spending time in, interacting with, and even just looking at natural environments can promote healthier body image outcomes. In this narrative review, I consider the different forms of evidence documenting an association between nature exposure and body image (i.e., cross-sectional and mediational, experimental and quasi-experimental, comparative, prospective, experience sampling, and qualitative research). Beyond this, I shine a critical light on the available evidence, highlighting concerns with methodological (i.e., who research has focused on and what types of natural environments have been considered), psychometric (i.e., how body image and nature exposure are measured), and conceptual issues (how the association is explained). I conclude that, although there are issues affecting the way the existing body of research is to be understood, there are reasons to be hopeful that nature exposure can be leveraged to promote healthier body image outcomes in diverse populations.
