Clinical relevance of a Body Image Scale cut point of 10 as an indicator of psychological distress in cancer patients: results from a psychiatric oncology clinic.

PURPOSE: Adequate adjustment to bodily changes during various phases of cancer treatment is important to patients' emotional well-being. The Body Image Scale (BIS) is a widely used tool for assessment of body image concerns in different cancer types. However, a cut point score indicative of clinically relevant body image concerns has not been established. The purpose of our study was to evaluate whether the previously suggested, but not validated, BIS cut point score of ≥ 10 is an adequate indicator of psychological distress. METHODS: In a prospective cross-sectional study, 590 adult patients were recruited from a psychiatric oncology clinic (November 2017-March 2018). Patient-reported body image concerns, depression, anxiety, and emotional distress were assessed with the BIS, Patient Health Questionnaire-9, Generalized Anxiety Disorder Scale-7, and National Comprehensive Cancer Network Distress Thermometer, respectively. RESULTS: Almost half of the patients had a BIS score ≥ 10; these were more likely to be younger, female, Hispanic, and to have breast cancer than patients with a score < 10. BIS scores were positively associated with depression, anxiety, and distress scores. A BIS score ≥ 10 was a significant predictor of moderate depression and anxiety (odds ratios = 3.555 [95% CI 2.478-5.102] and 3.655 [2.493-5.358]; p < 0.001 for both). CONCLUSION: To our knowledge, this is the first study to have assessed the validity of the previously suggested clinically relevant BIS cut point score of ≥ 10 as an indicator of psychological distress. Our results suggest that a BIS score of ≥ 10 or higher should lead to follow-up on body image concerns and/or appropriate referral.

No impact of hunger on male perception of female physical attractiveness in relation to adiposity: a randomized controlled trial.

BACKGROUND: Female physical attractiveness is strongly related to body mass index (BMI). Females with lower BMI are on average more attractive down to at least BMI = 18. Previous correlational studies have indicated that this effect may be modulated by the hunger of the rater, with more hungry raters preferring images of subjects with greater adiposity. This prior work, however, was correlational and so we wished to explore this phenomenon further using a randomized controlled trial. METHODS AND SUBJECTS: Two studies are presented. In the first, 52 male participants were recruited and after an overnight fast were randomly allocated to either fed or starved treatments. Starved individuals continued not to feed, while fed individuals were given ad libitum access to foods and were encouraged to eat to full satiation. Their hunger levels were monitored using visual analog scales (VAS) and levels of circulating glucose. Four hours later, they were asked to complete a previously used female attractiveness rating test, a standard IQ test, and a memory recall test. In the second study, which was a double-blind experiment, 32 individuals were recruited to evaluate if the original effect was due to a confounding impact of alcohol consumption when dining. Blinded individuals consumed drinks with or without alcohol. Their circulating alcohol levels were quantified by a breath test, and they repeated the tests matched with the first study excluding the IQ test. RESULTS: Hunger resulted in lower performance on the memory recall test, but had no effect on the IQ score, and contrasting previous results had no effect on the ratings of female physical attractiveness. Circulating alcohol levels had no effect on the memory recall test, but there was a significant negative relationship between circulating alcohol and the mean adiposity of the five individuals rated as least attractive. CONCLUSIONS: This randomized controlled trial failed to replicate previous nonrandomized observational studies, which had suggested that ratings of female physical attractiveness by males are sensitive to the levels of hunger. The reason for the difference was possibly because in previous studies, levels of hunger were confounded by alcohol consumption.

People who overvalue appearance selectively attend to descriptors of the attractiveness ideal: Findings from an emotional Stroop task.

OBJECTIVE: Attentional biases to stimuli related to stigmatized appearance are theorized to stem from appearance overvaluation, but little research has examined this link. As well, little research has examined whether appearance overvaluation is associated with biases toward stimuli that describe the attractiveness ideal. We addressed these gaps in the literature using the emotional Stroop task and tested whether appearance overvaluation is associated with an attentional bias for words that describe stigmatized appearance (e.g., fat, ugly, shabby), the attractiveness ideal (e.g., thin, beautiful, fashionable), or both. METHOD AND RESULTS: In Study 1, a community sample of people (N = 86) completed measures of appearance overvaluation, body dissatisfaction, and body mass index (BMI) followed by an emotional Stroop task. Appearance overvaluation was associated with an attentional bias for attractiveness ideal words-not stigmatized appearance words. Results remained significant when controlling for participants' body dissatisfaction, BMI, and gender. Study 2 (N = 316) replicated these findings. Finally, an integrative data analysis that pooled the data of Studies 1 and 2 (N = 402) provided additional support for our general hypothesis that people who overvalue appearance display an attentional bias to stimuli related to the attractiveness ideal. DISCUSSION: The results show a robust association between appearance overvaluation and selective attention for attractiveness ideal stimuli. Results are discussed in reference to theory and research on information processing in eating disorders. We also call for research to examine information processing of stimuli related to the attractiveness ideal among people with eating disorders and who place high importance on appearance for self-definition.

Video chatting and appearance satisfaction during COVID-19: Appearance comparisons and self-objectification as moderators.

OBJECTIVE: As video chatting has emerged as a leading form of communication for work, education, and socialization during the COVID-19 pandemic, it is important to investigate the association between video chatting and appearance satisfaction. METHOD: Participants included women from the United States (n = 438; age: M = 31.3, SD = 12.71) who completed measures examining their use of video chatting services, self-objectification, video chatting appearance comparison, and appearance satisfaction. RESULTS: The total time spent on video chatting services was not associated with appearance satisfaction; however, self-objectification moderated the relationship between total hours of video chatting and appearance satisfaction. In addition, participants who engaged in more video chatting appearance comparisons reported lower face and body satisfaction. Furthermore, video chatting appearance comparison was associated with more frequent usage of certain Zoom features, such as the "touch up my appearance" feature, and more time spent looking at oneself on video calls. Finally, those who spent more time engaged with their families over video chatting services reported greater face and body satisfaction. DISCUSSION: The results of the current study demonstrate that time spent video chatting is not predictive of appearance satisfaction, but that self-objectification can exacerbate these associations.

Deriving an overall appearance domain score by applying bifactor IRT analysis to the BODY-Q appearance scales.

PURPOSE: With the BODY-Q, one can assess outcomes, such as satisfaction with appearance, in weight loss and body contouring patients using multiple scales. All scales can be used independently in any given combination or order. Currently, the BODY-Q cannot provide overall appearance scores across scales that measure a similar super-ordinate construct (i.e., overall appearance), which could improve the scales' usefulness as a benchmarking tool and improve the comprehensibility of patient feedback. We explored the possibility of establishing overall appearance scores, by applying a bifactor model to the BODY-Q appearance scales. METHODS: In a bifactor model, questionnaire items load onto both a primary specific factors and a general factor, such as satisfaction with appearance. The international BODY-Q validation patient sample (n = 734) was used to fit a bifactor model to the appearance domain. Factor loadings, fit indices, and correlation between bifactor appearance domain and satisfaction with body scale were assessed. RESULTS: All items loaded on the general factor of their corresponding domain. In the appearance domain, all items demonstrated adequate item fit to the model. All scales had satisfactory fit to the bifactor model (RMSEA 0.045, CFI 0.969, and TLI 0.964). The correlation between the appearance domain summary scores and satisfaction with body scale scores was found to be 0.77. DISCUSSION: We successfully applied a bifactor model to BODY-Q data with good item and model fit indices. With this method, we were able to produce reliable overall appearance scores which may improve the interpretability of the BODY-Q while increasing flexibility.

Reactions to an Online Demonstration of the Effect of Increased Fruit and Vegetable Consumption on Appearance: Survey Study.

BACKGROUND: Inadequate fruit and vegetable consumption causes a considerable disease burden and premature mortality. Despite public health promotion of a healthy diet, the average consumption is still below recommended levels. Fruit and vegetable consumption influences human skin color, increasing red/yellow/orange pigment in the skin. Given that this color is deemed attractive and healthy-looking, the appearance benefit may motivate to eat more fruit and vegetables. Such appearance motivation could be particularly useful in young individuals who currently eat the least fruit and vegetables. OBJECTIVE: Our objectives were to assess how widely the impact of diet on skin color is known within the UK and to compare the strength of motivation to eat fruit and vegetables based on health and appearance benefits among different demographic groups. METHODS: Four groups of UK residents (N=200 per group) were recruited through the Prolific online platform. Groups comprised younger (aged 18-24) and older adults (aged 40-60) of low and high self-reported socioeconomic status (1-5 and 6-10 on a 10-point rating scale). Facial images simulating the skin color associated with low and high fruit and vegetable diets were shown to participants. Questionnaires were used to assess (1) background knowledge of the health and skin color effects of dietary fruit and vegetables, (2) the specific motivational impact of the skin color illustration, and (3) the relative importance of motivation to consume fruit and vegetables arising from health and skin color appearance benefits. RESULTS: We found that 61% (n=487) of all participants were unaware of the dietary-skin color association. We also found that 57% (n=457) of participants found the simple demonstration of the dietary impact on skin color positively motivating to eat more fruit and vegetables. The visual demonstration was equally motivating for participants of high and low self-reported socioeconomic status (P=.63) and different ethnic backgrounds (White N=453, Black N=182, Asian N=87, P=.22). Health benefits from a diet high in fruit and vegetables were regarded as more motivating than skin color appearance benefits. The appearance-changing benefits of a high fruit and vegetable diet (compared to the health benefits) were relatively more important for the younger participants (Mann-Whitney U=96,263, P<.001) and for women (N=489) than for men (N=310, U=83,763, P=.01). CONCLUSIONS: These findings indicate that the promotion of the skin color effects of diets high in fruit and vegetables could provide additional motivation for a healthier diet. Our study indicates the broad appeal of appearance benefits from dietary fruit and vegetable (across ethnicity and socioeconomic status) and particularly amongst young adults where an inadequate diet is most prevalent.

Looking for Mr(s) Right: Decision bias can prevent us from finding the most attractive face.

In realistic and challenging decision contexts, people may show biases that prevent them from choosing their favored options. For example, astronomer Johannes Kepler famously interviewed several candidate fiancées sequentially, but was rejected when attempting to return to a previous candidate. Similarly, we examined human performance on searches for attractive faces through fixed-length sequences by adapting optimal stopping computational theory developed from behavioral ecology and economics. Although economics studies have repeatedly found that participants sample too few options before choosing the best-ranked number from a series, we instead found overlong searches with many sequences ending without choice. Participants employed irrationally high choice thresholds, compared to the more lax, realistic standards of a Bayesian ideal observer, which achieved better-ranked faces. We consider several computational accounts and find that participants most resemble a Bayesian model that decides based on altered attractiveness values. These values may produce starkly different biases in the facial attractiveness domain than in other decision domains.

On the body of the consumer: performance-seeking with wearables and health and fitness apps.

Contributing to critical digital health research and the sociology of health consumption, this study investigates the phenomenon of self-tracking and interpretation of consumer data via wearable technology and mobile fitness software applications (apps). It critically analyses qualitative data collected from members of running communities in the UK who are heavy users of apps and wearables. The study seeks to understand the meaning and practise of long-term use of apps and wearables targeted at consumers interested in tracking fitness, and the collection of personal health information over time. The paper offers an interpretative perspective on runners as performance-seeking fitness consumers engaged in long-term self-management of health. These consumers are driven by a profound motivation to visualise and embody a long-term state of fitness. Participants were also hyper-aware of advertising and promotional methods used to engage consumers. The findings raise concerns about the validity of personal fitness data, and how its collection promises improved personal health while visually promoting sought-after fit bodies. Further research is required to understand the transformative impact of fitness-tracking and how individuals negotiate personal classifications of health.

Self-Competence and Depressive Symptoms in Middle-Late Adolescence: Disentangling the Direction of Effect.

This study examined the temporal relation between self-competence (academic, social, athletic, physical appearance, and close friend) and depressive symptoms in a large, diverse community sample of 636 adolescents. Surveys were administered to all 10th- and 11th-grade students at participating high schools at baseline (mean age = 16.10, SD = .71) and 1 year later. Girls reported higher levels of self-competence in close friendships and more depressive symptoms, whereas boys reported higher levels of self-competence in athletics and physical appearance. However, there were no gender differences in the associations between self-competence and depressive symptoms. Results from autoregressive, cross-lagged path analyses indicated that depressive symptoms predicted self-competence more consistently than self-competence predicted depressive symptoms during middle-late adolescence. Implications for prevention are discussed.

Lifestyle, appearance satisfaction and depressive symptoms in 13-16 years old Norwegian adolescents - A cross-sectional study.

Purpose: To examine gender-specific associations between multiple lifestyle-related risk factors, appearance satisfaction and depressive symptoms in a sample of Norwegian adolescents (13-16 years of age), and to study the role of appearance satisfaction as a possible confounder in the associations between lifestyle and depressive symptoms. Materials and methods: Data were obtained from Ungdata, a cross-sectional national survey of adolescents in Norway. In total 4379 subjects were included in the study. We constructed a lifestyle risk index and used multiple logistic regressions to examine the associations between lifestyle-related risk factors, appearance satisfaction, and depressive symptoms. Results: High screen time and use of alcohol were significantly associated with depressive symptoms among girls, while high screen time, tobacco and cannabis use were significantly associated with depressive symptoms among boys. An additive relationship was observed between the lifestyle risk index scores and the likelihood of depressive symptoms for both genders, the relationship being strongest among boys. Low appearance satisfaction was strongly associated with depressive symptoms, especially among boys, and identified as an important confounder in the associations between lifestyle and depressive symptoms, particularly among girls. Conclusions: High screen time was the most prevalent lifestyle risk behavior independently associated with depressive symptoms. Multiple lifestyle changes and improvement of appearance satisfaction should be included in measures targeting adolescents for the prevention and treatment of depressive symptoms. Future studies should elaborate on the gender differences in other adolescent age groups. Appearance satisfaction should be acknowledged as an important confounder in future studies of lifestyle and depressive symptoms.

Deformable torso phantoms of Chinese adults for personalized anatomy modelling.

In recent years, there has been increasing demand for personalized anatomy modelling for medical and industrial applications, such as ergonomics device development, clinical radiological exposure simulation, biomechanics analysis, and 3D animation character design. In this study, we constructed deformable torso phantoms that can be deformed to match the personal anatomy of Chinese male and female adults. The phantoms were created based on a training set of 79 trunk computed tomography (CT) images (41 males and 38 females) from normal Chinese subjects. Major torso organs were segmented from the CT images, and the statistical shape model (SSM) approach was used to learn the inter-subject anatomical variations. To match the personal anatomy, the phantoms were registered to individual body surface scans or medical images using the active shape model method. The constructed SSM demonstrated anatomical variations in body height, fat quantity, respiratory status, organ geometry, male muscle size, and female breast size. The masses of the deformed phantom organs were consistent with Chinese population organ mass ranges. To validate the performance of personal anatomy modelling, the phantoms were registered to the body surface scan and CT images. The registration accuracy measured from 22 test CT images showed a median Dice coefficient over 0.85, a median volume recovery coefficient (RCvlm ) between 0.85 and 1.1, and a median averaged surface distance (ASD) < 1.5 mm. We hope these phantoms can serve as computational tools for personalized anatomy modelling for the research community.

Distress from changes in physical appearance and support through information provision in male cancer patients.

OBJECTIVE: This study aims to reveal the present situation of changes in physical appearance induced by treatment, the effects of these changes on social activities, and support from medical staff in male cancer patients. METHODS: A questionnaire survey was administered to 949 male patients (response rate: 90.1%) visiting the National Cancer Center Hospital in Tokyo over 3 days in January 2015. RESULTS: The final respondents were 823 patients (mean age: 65.3, standard deviation (SD) = 12.32). Fifty-two percent of the sample, and 79.4% of patients aged under 65 were employed. A total of 84.9% experienced changes in physical appearance, and the highest mean scores of psychological were observed for stoma (3.1) and skin eczema (2.9). A total of 66.4% reported no difference in daily life even after their physical appearance changed. However, patients younger than 65 years old who were employed experienced high social difficulties (12.5%). Many wanted to stop going to work and experienced severe distress in their social lives; 74.1% reported it is important to have the same physical appearance at work as before treatment. The majority of patients obtained information from doctors (35.2%) and consulted with their wife or partner (66.2%) regarding their appearance changes, and 5.7% did not have anyone to consult with. CONCLUSION: This study clarified important aspects for supporting male cancer patients: timing, content, target audience and steps of information provision. Appropriate information provision from medical staff prior to treatment can be useful in preparing patients for physical appearance changes and decreasing the severity of symptoms.

A pilot investigation of the impact of smoking cessation on biological age.

BACKGROUND AND OBJECTIVES: Smoking is known to increase biological age. However, whether this process is reversible through smoking cessation is not known. In this pilot study, we attempt to determine whether smoking cessation reduces biological age. METHODS: We conducted regression analyses of methylation data from 22 subjects, as they entered and exited inpatient substance use treatment, to determine change in biological age, as indicated by the deviation of their methylomic age from chronological age across two time points. RESULTS: We found that, as compared to those subjects who did not stop smoking, subjects who significantly decreased their smoking consumption over a 1 month time period exhibited a marked reduction in methylomic age. CONCLUSION: The rapid and substantial reversal of accelerated aging associated with successful smoking cessation suggests that it can reverse well-known smoking effects on methylomic aging. This preliminary finding can be readily examined in other, larger data sets, and if replicated, this observation may provide smokers with yet another good reason to quit smoking. SCIENTIFIC SIGNIFICANCE: Successful smoking cessation makes patients appear biologically younger than they were at baseline, and to do so quite rapidly. In today's youth driven society, our observations may serve as a powerful impetus for some to quit smoking. (Am J Addict 2017;26:129-135).

Own Attractiveness and Dissatisfaction With Physical Appearance Independently Predict the Salience of Facial Cues to Size When Women Judge Other Women's Attractiveness.

While facial cues to body size are a valid guide to health and attractiveness, it is unclear whether the observer's own condition predicts the salience of (low) size as a cue to female attractiveness. The current study examines whether measures related to women's own attractiveness/appearance predict the extent to which they use facial cues to size to differentiate other women on the attractiveness dimension. Women completed a body mass index (BMI) preference task, where they indicated their preference for high- versus low-BMI versions of the same woman, provided data to calculate their BMI and completed various psychometric measures (self-rated attractiveness/health, dissatisfaction with physical appearance). Here, attractive women and women who were dissatisfied with their own appearance were more likely to associate facial cues to low body size with high attractiveness. These data suggest that psychological factors related to women's appearance shape their evaluations of other women based on cues to size. Such variation in attractiveness judgements may function to reduce the costs of female competition for resources, for example, by identifying "quality" rivals or excluding others based on cues to size.

Facial-Attractiveness Choices Are Predicted by Divisive Normalization.

Do people appear more attractive or less attractive depending on the company they keep? A divisive-normalization account-in which representation of stimulus intensity is normalized (divided) by concurrent stimulus intensities-predicts that choice preferences among options increase with the range of option values. In the first experiment reported here, I manipulated the range of attractiveness of the faces presented on each trial by varying the attractiveness of an undesirable distractor face that was presented simultaneously with two attractive targets, and participants were asked to choose the most attractive face. I used normalization models to predict the context dependence of preferences regarding facial attractiveness. The more unattractive the distractor, the more one of the targets was preferred over the other target, which suggests that divisive normalization (a potential canonical computation in the brain) influences social evaluations. I obtained the same result when I manipulated faces' averageness and participants chose the most average face. This finding suggests that divisive normalization is not restricted to value-based decisions (e.g., attractiveness). This new application to social evaluation of normalization, a classic theory, opens possibilities for predicting social decisions in naturalistic contexts such as advertising or dating.

Evolving eating disorder psychopathology: conceptualising muscularity-oriented disordered eating.

Eating disorders, once thought to be largely confined to females, are increasingly common in males. However, the presentation of disordered eating among males is often distinct to that observed in females and this diversity is not accommodated in current classification schemes. Here, we consider the diagnostic and clinical challenges presented by these distinctive presentations.

A humidity sensitive two-dimensional tunable amorphous photonic structure in the bivalve ligament of Meretrix linnaeus.

A humidity sensitive two-dimensional tunable amorphous photonic structure (2D TAPS) in the bivalve ligament of Meretrix linnaeus (LML) was reported in this paper. The structural color and microstructure of LML were investigated by reflection spectra and scanning electron microscopy, respectively. The results indicate that the LML has complex structural colors from blue to orange in the wet state from ventral to dorsal, which are derived from the aragonite fiber diameter increases continuously from ventral to dorsal of the ligament. The reflection peak wavelength of the wet LML can blue-shift from 522 nm to 480 nm with the air drying time increased from 0 to 60 min, while the reflectivity decreases gradually and only a weak reflection peak at last, relevant color changes from green to light blue. The structural color in the LML is produced by a two-dimensional amorphous photonic structure consists of aligned aragonite fibers and proteins, in which the diameters of the aragonite fiber and the inter-fiber spacing are 104±11 nm and 126±16 nm, respectively. Water can reversibly tune the reflection peak wavelength and reflectivity of this photonic structure, and the regulation achieved through dynamically tune the degree of order and lattice constant of the ligament in the different wet states.

The recognition of 18 facial-bodily expressions across nine cultures.

An enduring focus in the science of emotion is the question of which psychological states are signaled in expressive behavior. Based on empirical findings from previous studies, we created photographs of facial-bodily expressions of 18 states and presented these to participants in nine cultures. In a well-validated recognition paradigm, participants matched stories of causal antecedents to one of four expressions of the same valence. All 18 facial-bodily expressions were recognized at well above chance levels. We conclude by discussing the methodological shortcomings of our study and the conceptual implications of its findings.

Different conformations of the German shepherd dog breed affect its posture and movement.

The conformation of the German shepherd dog (GSD) varies considerably within the breed. These differences may result in large variation in the movement and limb loading and undesirable consequences to their musculoskeletal health. This study aimed to investigate the relationship between conformation and biomechanical measures in 60 GSDs. Full body kinematic and kinetic measures were computed from 3D motion capture and pressure data. The dogs were divided into groups based on their back slope and curvature. Correlation analysis and statistical differences between groups showed that GSDs with a greater back slope have a greater contact area in their forelimbs and place them closer together when standing (n = 60). During trot, the dogs with sloped back showed a greater vertical force in the forelimbs and a greater mid-thoracic flexion (n = 60). Unilateral differences were found in the stifle flexion, hock flexion and hock adduction, suggesting greater movement asymmetry with an increase in the back slope (n = 30). In conclusion, several biomechanical parameters are affected by the GSD's slope of the back and not by its curvature. Further studies are required to determine whether the variation in movement, posture and conformation within the breed relates to an increased susceptibility to musculoskeletal disorders.
