Contribuições do profissional de psicologia para o paciente em cuidados paliativos / Contributions of the psychology professional to the patient in palliative care / Aportaciones del profesional de la psicología para el paciente en cuidados paliativos

Os cuidados paliativos englobam uma filosofia de cuidados que objetivam a promoção da qualidade de vida e alívio do sofrimento, tanto para o paciente fora de possibilidades de cura quanto aos seus familiares, de modo que possa integrar aspectos de ordem física, psíquica, social e espiritual. O presente artigo buscou, a partir do estudo de revisão bibliográfica, compreender o processo da morte e sua implicância psíquica na vida do paciente em cuidados paliativos para, posteriormente, elencar as possíveis contribuições do profissional de psicologia ao mesmo. Observou-se que a atuação do psicólogo nesse âmbito é de imensa importância, uma vez que o processo de adoecer e morrer permeiam a vida do ser humano, causando-lhe grande sofrimento. Percebeu-se também que as ações do psicólogo se dão no sentido de tornar a morte e seus impactos mais suportáveis, por meio da escuta, do acolhimento emocional, dentre outros aspectos importantes que se referem à sua natureza científica.

Palliative care encompasses a philosophy of care aimed at promoting quality of life and alleviating suffering, both for the patient with no chance of cure and for their family members, so that they can integrate physical, psychic, social and spiritual aspects. The present article sought, from the study of literature review, to understand the process of death and its psychic implications in the life of the patient in palliative care to, later, list the possible contributions of the psychology professional to it. It was observed that the role of the psychologist in this context is of immense importance, since the process of falling ill and dying permeates the life of human beings, causing them great suffering. It was also noticed that the psychologist's actions take place in the sense of making death and its impacts more bearable, through listening, emotional reception, among other important aspects that refer to its scientific nature.

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.

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.

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.

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.

Relationship between the self-concept and physical activity towards the prevention of chronic illnesses.

The objective of this work is to verify the relationship between the self-perception of health and the self-concept of physical appearance in adolescents, in order to check their influence on the physical activity they perform with the aim of preventing chronic illnesses. To this end, an observational, cross-sectional descriptive study with analytical components was carried out. Opportunistic activity, in which young people, between the ages of 16 and 22, were recruited from 5 secondary schools of the municipality of San Cristóbal de La Laguna, on the island of Tenerife (Spain). Data were collected through the General Health Questionnaire, the Rosemberg Self-esteem Scale, and the physical exercise habits test physical activity questionnaire for adolescents-A, revealing the first 2 that most percentage of responses were grouped on the positive side. The physical exercise habits test physical activity questionnaire for adolescents-A described that the most commonly performed physical activity was walking (75%).

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.

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.

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.

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.

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.

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.

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.

Trending on Pinterest: an examination of pins about skin tanning.

Rates of melanoma and nonmelanoma skin cancers are on the rise in the USA with data revealing disproportionate increase in female young adults. The popularity of intentional skin tanning among U.S. adolescents is attributed to several factors, including prioritization of physical appearance, media images of tanned celebrities, ease of availability of artificial tanning facilities, and more recently, the prevalence and celebration of tanned skin on social media. Pinterest, as the third most popular social media platform, was searched for "pins" about skin tanning. The resultant "pins" were examined to understand the extent and characteristics of skin tanning portrayed on Pinterest. We analyzed pins on Pinterest about skin tanning (n = 501) through a quantitative content analysis. Overall, results indicated an overwhelmingly protanning characteristic of pins about skin tanning on Pinterest, with over 85% of pins promoting tanning behavior. The pins were generally characterized by the portrayal of a female subject (61%) and provided positive reinforcement for tanning (49%). Use of tanning for enhancing appearance was the main positive outcome expectancy portrayed in the pins (35%), and nudity or exposure of skin on arms (32%) and legs (31%) was evident in about a third of pins. With overwhelmingly positive pins promoting tanning, use of female subjects, exhibiting nudity, and appearance enhancement, there seems be to a consistent targeting of female users to accept tanning as a socially acceptable and popular behavior. The findings indicate a need for developing sun protection messages and the leveraging of social media for dissemination of skin cancer prevention and detection messages.

Emotional responses to disfigured faces and Disgust Sensitivity: An eye-tracking study.

Facial disfigurement attracts attention and evokes negative emotion, but evidence is lacking for a link between these two reactions. The present experiment (n = 29) investigated emotional and attentional reactions to photographs of people with disfigured faces. An eye-tracker was used to measure fixation on internal expressive features and on the forehead. Disfigurement to the internal expressive features invoked a stronger emotional reaction than disfigurement to the forehead. Attention in the area of disfigurement was associated with negative emotion (embarrassment, sympathy, disgust, repulsion) as well as surprise. Attention to the disfigurement, and negative emotion, was related to the trait of Disgust Sensitivity.

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.

No compelling evidence that more physically attractive young adult women have higher estradiol or progesterone.

Putative associations between sex hormones and attractive physical characteristics in women are central to many theories of human physical attractiveness and mate choice. Although such theories have become very influential, evidence that physically attractive and unattractive women have different hormonal profiles is equivocal. Consequently, we investigated hypothesized relationships between salivary estradiol and progesterone and two aspects of women's physical attractiveness that are commonly assumed to be correlated with levels of these hormones: facial attractiveness (N = 249) and waist-to-hip ratio (N = 247). Our analyses revealed no compelling evidence that women with more attractive faces or lower (i.e., more attractive) waist-to-hip ratios had higher levels of estradiol or progesterone. One analysis did suggest that women with more attractive waist-to-hip ratios had significantly higher progesterone, but the relationship was weak and the relationship not significant in other analyses. These results do not support the influential hypothesis that between-women differences in physical attractiveness are related to estradiol and/or progesterone.

Estrategias para el manejo del cuerpo en adultos jóvenes: interacción entre las percepciones corporales, la edad y el sexo / Body management behaviors in young adults: interactions among body perceptions, age and gender

La percepción del cuerpo y la satisfacción con el mismo se asocian con conductas saludables y de riesgo de manejo del cuerpo con importantes consecuencias para la salud. En este estudio se exploran las conductas que usan hombres y mujeres en su adultez temprana para controlar el peso, tamaño, forma y composición corporales. La imagen corporal (IC) y la satisfacción corporal (SC) se evaluaron a través de siluetas, preguntas y discrepancias, y las prácticas conductuales de control del cuerpo a través de un cuestionario. Los participantes informaron de un uso moderadamente elevado de estrategias saludables y bajo de estrategias de riesgo. ANOVAs de 2 y 3 factores indicaron que una IC más negativa y una SC menor se asocian con un mayor uso de estrategias saludables y, particularmente, de riesgo de manejo del cuerpo, y que el sexo, y no tanto la edad, modera esta relación, mostrando las mujeres mayor uso de ambos tipos de estrategias. Nuestros resultados son interesantes para el diseño de intervenciones destinadas a mejorar las percepciones corporales basadas en conductas saludables

Body perceptions and body satisfaction are associated with healthy and risk body change behaviors with important consequences for health. In this study, the behaviors that men and women in their early young adulthood and late young adulthood used to control body weight, size, shape, and composition were explored. Body image (BI) and body satisfaction (BS) were assessed through silhouettes, questions and discrepancies, and body management behavioral practices with a questionnaire. Participants reported a moderately high use of healthy strategies and low use of maladaptive strategies. Two- and three-way between-subjects ANOVAs indicated that a more negative BI and lower BS were associated with a greater use of both healthy and, particularly, risk body management strategies, and that gender, more than age, moderates this relationship, with women demonstrating a higher use of both type of bodymanagement strategies. Our results are interesting for the design of interventions aimed at improving body perceptions with a focus on healthy behaviors

Female Japanese quail visually differentiate testosterone-dependent male attractiveness for mating preferences.

Biased mating due to female preferences towards certain traits in males is a major mechanism driving sexual selection, and may constitute an important evolutionary force in organisms with sexual reproduction. In birds, although the role of male ornamentation, plumage coloration, genetic dissimilarity, and body size have on mate selection by females have been examined extensively, few studies have clarified exactly how these characteristics affect female mate preferences. Here, we show that testosterone (T)-dependent male attractiveness enhances female preference for males of a polygamous species, the Japanese quail. A significant positive correlation between female mating preference and circulating T in the male was observed. The cheek feathers of attractive males contained higher levels of melanin and were more brightly colored. The ability of females to distinguish attractive males from other males was negated when the light source was covered with a sharp cut filter (cutoff; < 640 nm). When females were maintained under short-day conditions, the expression of retinal red-sensitive opsin decreased dramatically and they became insensitive to male attractiveness. Our results showed that female preference in quail is strongly stimulated by male feather coloration in a T-dependent manner and that female birds develop a keen sense for this coloration due to upregulation of retinal red-sensitive opsin under breeding conditions.
