RESUMEN

Individuals with dark personality traits are more prone to burnout, but this was not yet investigated in academia. Perfectionistic self-presentation (PSPS), an interpersonal expression of perfectionism, could be an explaining factor. Therefore, we investigated the relationship between the dark triad (Machiavellianism, vulnerable and grandiose narcissism, and psychopathy) and academic burnout, and whether the PSPS total score and its dimensions (perfectionistic self-promotion, nondisplay of imperfection, and nondisclosure of imperfection) mediates this. We expected that higher dark triad traits would be associated with higher academic burnout and that this would be explained by higher PSPS. Hypotheses included expectations for each PSPS dimension as well. Questionnaires were completed by 304 bachelor/master students (Mage = 22.81 years). Mediations were performed for each dark triad trait with total PSPS and each of its dimensions separately as mediator, and academic burnout as dependent variable. Total PSPS and almost all of its dimensions positively and significantly mediated the relation between Machiavellianism as well as psychopathy and academic burnout (small effect sizes). In contrast, only the PSPS dimension nondisplay of imperfection was a significant, positive mediator of the relation between grandiose narcissism and academic burnout (medium effect size). The other mediations with grandiose or vulnerable narcissism were non-significant. Future research should investigate this further, for instance by using the standard dark triad scales. Finally, this study offers insights for interventions and prevention of academic burnout by highlighting the unique impact of each dark triad trait. For example, those high on Machiavellianism may benefit from tools to deal with cynicism and perfectionism, ultimately lowering the risk for academic burnout.

RESUMEN

BACKGROUND: Social media use, perfectionism, and disordered eating have all increased over the last decades. Some studies indicate that there is a relationship between self-presentation behaviors and being exposed to others' self-presentation on social media, and disordered eating. Studies also show that the relationship between focus on self-presentation and highly visual social media is stronger than for non-visual social media, hence facilitating upward social comparison. Nevertheless, no previous studies have investigated the link between adolescents' focus on self-presentation and upward social comparison on social media, and perfectionism and disordered eating, which is the aim of the present study. METHOD: The present study is based on a cross-sectional survey from the "LifeOnSoMe"-study (N = 3424), conducted in 2020 and 2021. Respondents were high school students (mean age 17.3 years, 56% females) in Bergen, Norway. Multiple regression analysis was performed, where SPAUSCIS, a measure of self-presentation and upward social comparison, was the independent variable. Perfectionism and disordered eating were dependent variables. Self-reported age, gender, and subjective socioeconomic status were used as covariates, as well as frequency and duration of social media use. Regression models were performed to compare proportions across the median split of SPAUSCIS. RESULTS: The multiple regression analysis showed that increased focus on self-presentation and upward social comparison on social media were positively associated with both perfectionism (standardized coefficient 0.28) and disordered eating. A stronger association for girls than boys was found for disordered eating (standardized coefficient 0.39 for girls and 0.29 for boys). There was no gender moderation for perfectionism. CONCLUSIONS: Findings suggest that focus on self-presentation and upward social comparison on social media is associated with perfectionism and disordered eating. We recommend promoting a healthy use of social media. This could be established by increasing adolescents' ability to reflect on and think critically about self-presentation and upward social comparison on social media.

RESUMEN

Mobile Dating Applications (MDAs) are integral to young adults' lives, serving as a platform for romantic and sexual self-presentation during the search for potential partners. Despite its potential link to adverse outcomes including body shame, the prevalence of sexualized self-presentation remains understudied. This pre-registered linkage study addresses this gap by documenting sexualized self-presentation while considering individual differences related to gender, sexual orientation, and body image. Young adults donated MDA (Tinder, Bumble) profile screenshots (nbiographies = 443, npictures = 1277; Mage = 23.15, SD = 2.94; 72.20 % women). Of those 443 participants, 237 additionally completed a body image linkage survey (Mage = 23.36, SD = 2.90; 71.30 % women). Sexualized self-presentation appeared in 4.30 % of biographies and 56.80 % of profile pictures, mainly through sexualized facial expressions. Women, non-heterosexual users, and those holding a more negative body image engaged more in sexualized self-presentation. Platform type and positive body image indicators did not relate to engagement in sexualized self-presentation. Future research is recommended to explore whether the extensive presence of sexualized self-presentations on MDAs impacts users' personal and relational well-being.

RESUMEN

The current research on ST elevation myocardial infarction (STEMI) patients has been mostly limited to Door-to-Balloon (D-to-B) time. This study aimed to compare the effects of different hospital admission modes to on the time metrics of patients undergoing primary percutaneous coronary intervention (PPCI). It also examined the effects of these modes on in-hospital mortality and other influencing factors. The goal was to prompt healthcare facilities at all levels, including chest hospitals, the Centers for Disease Control and Prevention (CDC), and communities to take measures to enhance the treatment outcomes for patients with STEMI. A total of 1053 cases of STEMI patients admitted to Tianjin Chest Hospital from December 2016 to December 2023 and successfully underwent PPCI were selected for this study. They were divided into three groups based on the admission modes: the ambulances group (363 cases), the self-presentation group (305 cases), and the transferred group (385 cases). Multivariate logistic regression was used to explore the impact of different modes of hospital admission on the standard-reaching rate of key treatment time metrics. The results showed that the S-to-FMC time of transferred patients (OR = 0.434, 95% CI 0.316-0.596, P < 0.001) and self-presentation patients (OR = 0.489, 95% CI 0.363-0.659, P < 0.001) were more likely to exceed the standard than that of ambulance patients; The cath lab pre-activation time of self-presented patients was also less likely to meet the standard than that of ambulance patients (OR = 0.695, 95% CI 0.499-0.967, P = 0.031); D-to-W time of self-presentation patients was less likely to reach the standard than that of ambulance patients (OR = 0.323, 95% CI 0.234-0.446, P < 0.001);However, the FMC-to-ECG time of self-presentation patients was more likely to reach the standard than that of ambulance patients (OR = 2.601, 95% CI 1.326-5.100, P = 0.005). The Cox proportional hazards model analysis revealed that for ambulance patients, the time spent at each key treatment time point is shorter, leading to lower in-hospital mortality rate (HR0.512, 95% CI 0.302-0.868, P = 0.013) compared to patients admitted by other means. We found that direct arrival of STEMI patients to the PCI hospital via ambulance at the onset of the disease significantly reduces the S-to-FMC time, FMC-to-ECG time, D-to-W time, and catheterization room activation time compared to patients who self-present. This admission mode enhances the likelihood of meeting the benchmark standards for each time metric, consequently enhancing patient outcomes.

RESUMEN

Inflammatory Bowel Disease often causes abdominal pain, faecal urgency and a range of other symptoms, and is a common chronic disease among young people. Stoma surgery seeks to alleviate these symptoms, though complications often arise from surgery and many stoma patients experience various stigmas. Young people with chronic conditions are increasingly gathering online to share their experiences of illness. Given the rise in popularity of TikTok and its appeal to young people, this study explored how young ostomates with Inflammatory Bowel Disease and a stoma portray themselves on TikTok. Using thematic analysis, three themes were identified in which ostomates portrayed themselves as educators, warriors and reformers, providing education, support and guidance to the wider stoma community. These findings show that TikTok offers an innovative platform for ostomates' self-presentations and a novel space health professionals should harness to better support ostomates.

RESUMEN

The current research evaluates the Perfectionism Social Disconnection Model (PSDM) by considering the links between measures of trait perfectionism and perfectionistic self-presentation and measures of social support, loneliness, and distress in cross-sectional research. A particular focus is on perfectionism and levels of social support as assessed by the Social Provisions Scale. The current study also uniquely evaluates levels of perfectionism and perfectionistic self-presentation in undergraduate students, medical students, and law students. The results across samples provided evidence that loneliness mediates the link between interpersonal perfectionism and distress in keeping with the predictions of the PSDM. Correlational results found robust links between loneliness and low levels of social support. Moreover, socially prescribed perfectionism and perfectionistic self-presentation were associated negatively with social support, and this was especially evident in terms of the facet tapping the nondisclosure of imperfections. Group comparisons of perfectionism yielded few significant differences in accordance with expectations. Levels of perfectionism tended to be lower among medical students. However, the links between perfectionism and distress were clearly evident among undergraduates, medical students, and law students, thus attesting to the vulnerability of perfectionistic students in general. Overall, the results further confirm the relevance of perfectionism in distress among students and applicability of the PSDM in various types of students.

RESUMEN

This research focuses on ego-focused self-image goals as central to understanding the vulnerability inherent in perfectionism and the link that perfectionism has with poorer health and emotional well-being. The present study expands theory and research on perfectionism from a unique motivational perspective through a longitudinal investigation of perfectionism, the pursuit of self-image goals related to self-improvement, and mental and physical health among 187 university students. Our central finding was that trait and self-presentational perfectionism were associated longitudinally with self-image goals and poorer mental and physical health. Longitudinal analyses showed that perfectionistic self-presentation predicted subsequent self-image goals, controlling for initial self-image goals. Additionally, self-image goals were associated with worse mental and physical health and greater loneliness and social anxiety. Collectively, our results illustrate the benefits of assessing problematic personal goals in perfectionism and the need to revise existing motivational accounts by recognizing the important role ego-involved goals play in guiding much of what perfectionists do and how they act in their daily lives.

RESUMEN

Few theoretical and empirical works have described impostor phenomenon (IP) and no study explored impostorism from a dark perspective. We adopted a person-centered approach to identify clusters of impostors based on scores on the IP, perfectionistic self-presentation and the Dark Triad using a sample of 306 university students (Mage = 22.82). The latent profile analysis suggested a 6-cluster solution, which was further compared in terms of psychopathology symptoms (i.e., burnout, generalized anxiety, and fear of failure) by means of (M)ANOVAs. Our results indicated that impostorism relies on a self-presentation strategy. Moreover, individuals scoring high on IP experienced enhanced levels of psychopathology symptoms. Looking at IP from a continuum perspective might improve our understanding about what makes someone suffer from impostorism.

RESUMEN

Insufficient antigen self-presentation of tumor cells and ineffective antigen cross-presentation by dendritic cells (DCs) contribute to diminished immune recognition and activation, which cause resistance to immunotherapies. Herein, we present an ultrasound-activatable in situ vaccine by utilizing a hybrid nanovesicle composed of a thylakoid (TK)/platelet (PLT) membrane and a liposome encapsulating DNA methyltransferase inhibitor zebularine (Zeb) and sonosensitizer hematoporphyrin monomethyl ether (HMME). Upon local exposure to ultrasound, reactive oxygen species (ROS) are generated and induce the sequential release of the payloads. Zeb can efficiently inhibit tumor DNA hypermethylation, promoting major histocompatibility complex class I (MHC-I) molecules-mediated antigen self-presentation to improve immune recognition. Meanwhile, the catalase on the TK membrane can decompose the tumoral overexpressed H2O2 into O2, which boosts the generation of ROS and the destruction of tumor cells, resulting in the in situ antigen release and cross-presentation of tumor antigens by DCs. This in situ vaccine simultaneously promotes antigen self-presentation and cross-presentation, resulting in heightened antitumor immunity to overcome resistance.

RESUMEN

This linkage study examined the prevalence of traditional gender expressions in the textual and visual profile cues on mobile dating applications (MDA) (nbiographies = 396, npictures = 1352) of 396 young adults' (Mage = 22.39 years, SD = 2.86, 73% women) with attention to users' gender, sexual orientation, and platform type. For 184 users (Mage = 22.10 years, SD = 2.91, 75% women) media content data were linked to self-report survey data. Results showed that individuals aligned their self-presentations with traditional gender roles and expectations, and this link depended on their gender. No significant differences according to individuals' sexual orientation or platform type were found. Individuals' (hyper-) gender orientation also related to engagement in traditional gender expressions. Specifically, women with a stronger feminine gender orientation expressed more traditional femininity in their MDA profiles. For men, no significant associations between (aspects of) a masculine gender orientation and expressing traditional masculinity in their MDA profiles were found. Future research should further disentangle selective gendered self-presentations.

RESUMEN

Intrinsic (i.e., personality traits) and extrinsic mate value (i.e., resources, physical attractiveness) preferences play a crucial role in (online) relationship formation. The role of mate values in dating applications was unclear and was addressed in a multi-method study. A first content analytical study examined the prevalence of mate values (MVs) on Tinder profiles (Study 1) and two subsequent cross-sectional studies explored the relationships between dating app use, various swiping behaviors, sexual satisfaction (Studies 2-3), need satisfaction with matches (Study 3), having a committed relationship versus casual sex motivation for using dating apps and users' gender. The content analysis of 307 Tinder profiles indicated that resources and physical attractiveness were most salient in biographies and pictures, respectively. The first cross-sectional study (nfullsample = 325, ndating app users = 133) revealed no significant relationships between dating app frequency/swiping frequency, intrinsic and extrinsic MV preferences, and sexual satisfaction. The second cross-sectional study (n = 323) showed no significant relationships between picture-based or biography-based swiping, intrinsic and extrinsic MV preferences, and need satisfaction with matches. Gender differences emerged in the presentation of MVs on Tinder (Study 1) and general MV preferences (Study 2-3), but not in the relationships between different types of dating app use/swiping and MV preferences (Study 2-3). A committed relationship and a casual sex motivation played a role in the relationships between different types of swiping behaviors and MV preferences, and between MV preferences, and sexual satisfaction/need satisfaction with matches.

RESUMEN

This study examined the relationship between the impostor phenomenon, self-esteem, online self-presentation, and social network site usage across Instagram, Facebook, TikTok, LinkedIn, and Tinder. The sample consisted of n = 541 individuals (46 % men; Mage = 27, SDage = 8.5). In addition to demographics, quantitative social network site use metrics, and self-esteem, the impostor expression emerged as an incremental predictor for the online self-presentation facets adaptable self (ß = 0.26, p < .001), authentic self (ß = -0.29, p < .001) and freedom of self online (ß = 0.25, p < .001). Self-esteem partially mediated the impostor expression's effect on the authentic self. Findings suggest that a high impostor expression links to lower online authenticity, higher online self-adaption, and a preference for online communication and self-presentation.

RESUMEN

Scholars of color remain underrepresented in US institutions in academia. In this paper, we will examine one factor that contributes to their continued marginalization in psychology and management: the scientific method's commitment to traditional notions of objectivity. We argue that objectivity-defined as practices and policies rooted in the heightened value placed on a research process that is ostensibly free from bias-is central to the prominence of primarily White scholarship in psychology and management research and remains central to knowledge production. To investigate this, we employ a mixed-methods approach, integrating qualitative and quantitative data to codify how scholars of color experience objectivity interrogations, or written and verbal questioning in academic contexts that implicates their scientific rigor. We also identify how scholars of color engage in objectivity armoring, or self-presentational strategies (toning down and stepping up) to contend with these interrogations. Finally, we reveal these toning down processes in language use within publications on racial scholarship. Overall, these studies reveal the unique challenges scholars of color face to legitimize and validate their work on race and racism within predominantly White institutions and disciplines.

RESUMEN

BACKGROUND: The darknet hosts an increasing number of hidden services dedicated to the distribution of child sexual abuse material (CSAM). Given that by contributing CSAM to the forum members subject themselves to criminal prosecution, questions regarding the motivation for members contributing to darknet CSAM forums arise. OBJECTIVE: Building on insights gained from research into clearnet communities, here we examine the extent to which social incentives generated by the online CSAM community may explain members' posting behavior on darknet CSAM forums. PARTICIPANTS AND SETTING: We analyze digital forensic artifacts on the online behavior of members of a darknet CSAM forum that was shut down by law enforcement agencies in July 2015. METHODS: We apply group-based trajectory modelling (GBTM), social network analysis, and mixed-effect survival models. RESULTS: Applying GBTM three posting trajectories can be distinguished. Social network analyses finds the reply network to be more centralized than predicted by chance. Mixed-effect survival models show positive associations between the length of members' first post and the time since members' first registration on the forum and subsequent posting. Contrarily, the number of replies received appears to mitigate subsequent posting. CONCLUSIONS: Findings show posting activity on the forum to be concentrated in a minority of forum members who show posting trajectories that are both frequent and persistent. Results further suggest persistence in posting is motivated by social identity and, to a lesser extent, differential association processes.

RESUMEN

Objective: The negative effects of Problematic Instagram Use (PIU) on self-evaluations of one's appearance (i.e., body-image satisfaction-dissatisfaction) are well-known, whereas less explored is its role on body-image investment dimensions. By adopting the Social Comparison and the Self-discrepancies theories as the framework, the present study hypothesized that PIU negatively affects body investment and appearance management behaviours through the serial mediating role of actual appearance comparison on Instagram (IG) and the need to conceal body flaws. Gender, age and trait appearance comparison were controlled for. Method: A convenience sample of 323 participants (F = 70.3%; M= 28.92 + 10.96) was recruited, and well-known self-report measures were administered online. Results: The structural model produced good fit indices [χ2/df = 2.36, RMSEA = 0.065 (0.053 - 0.077), CFI = 0.962, SRMR = 0.038], and the variables accounted for 79% and 32% of the variance in body investment and appearance management behaviours, respectively. PIU was associated with body investment both directly and indirectly, whereas it affected appearance management behaviours only via appearance comparison on Ig. The tested alternative model has a poorer fit than the hypothesized model, and the former fitted significantly worse than the proposed one. Conclusions: The present study represents a step toward a better understanding of the psychological mechanisms underlying the link between PIU and body image investment dimensions.

RESUMEN

Decades of research implicate perfectionism as a risk factor for psychopathology. Most research has focused on trait perfectionism (i.e., needing to be perfect), but there is a growing focus on perfectionistic self-presentation (PSP) (i.e., the need to seem perfect). The current article reports the results of a meta-analysis of previous research on the facets of PSP and psychopathology outcomes (either clinical diagnoses of psychiatric disorders or symptoms of these disorders). A systematic literature search retrieved 30 relevant studies (37 samples; N = 15,072), resulting in 192 individual effect-size indexes that were analysed with random-effect meta-analysis. Findings support the notion of PSP as a transdiagnostic factor by showing that PSP facets are associated with various forms of psychopathology, especially social anxiety, depression, vulnerable narcissism and-to lesser extent-grandiose narcissism and anorexia nervosa. The results indicated that there both commonalities across the three PSP and some unique findings highlighting the need to distinguish among appearing perfect, avoiding seeming imperfect and avoiding disclosures of imperfections. Additional analyses yielded little evidence in the results across studies including undergraduates, community samples and clinical samples. Our discussion includes a focus on factors and processes that contribute to the association between PSP and psychopathology.

RESUMEN

This study examined how evaluations of self-presentation vary with age depending on the self-presenter's usual performance. People's usual performance is a key factor because it generally influences the social evaluations and judgments that others make about them. Children aged 7 and 8 years (second graders) and 10 and 11 years (fifth graders), as well as adults, were presented with scenarios in which protagonists responded to praise after a good performance using either self-enhancement or self-deprecation. The other person in scenarios knew that the protagonist's usual performance on the task was either good or poor. After the protagonist responded to praise in a self-enhancing or self-deprecating way, the participants judged how the other person would evaluate the protagonist's ability (good/poor) and character (nice/mean). For ability evaluations specifically concerning protagonists who usually performed poorly, the results showed that by around 10 years of age children no longer tended to give more positive ability evaluations for self-enhancement than for self-deprecation. Adults gave less positive ability evaluations for self-deprecation than for self-enhancement, but only when the protagonists usually performed well. In relation to the character evaluations, by around 10 years of age self-enhancement led to less positive character evaluations than self-deprecation, but only when the protagonists usually performed poorly. Overall, second graders evaluated self-presenters as more competent and nicer. These results indicate that the expected evaluation of self-enhancement and self-deprecation is influenced by the usual level of performance but that there are developmental changes in this aspect of social cognition.

RESUMEN

Social media serves as one of the primary outlets for self-presentation and receiving social support. Even when individuals portray themselves negatively, it might not necessarily be intended for social disapproval. Conversely, positive self-presentation doesn't always guarantee social support. This study examined the relationship between positive and negative fitness self-presentations on social media and the reception of supportive feedback. Additionally, it investigated how social support might influence individuals' self-efficacy, motivation, and participation in physical activities (PA). Participants were fitness app users recruited from a crowdsourcing internet marketplace who had shared their fitness experiences on social media. The results indicated that both types of self-presentation received social support: presenters receiving more social support showed higher self-efficacy for PA. Moreover, fitness posters with higher self-efficacy in PA showed greater motivation for PA. This research suggests that fitness self-presentation allows users to receive social support, fostering confidence and motivation for engaging in PA.

RESUMEN

People tend to make positive self-presentations on social networking sites (SNS). We aim to compare people's attitudes toward others' positive self-presentations on SNS and its mechanism. The sample in Experimental 1 included 71 Chinese college students. We measured participants' attitudes to others' positive self-presentation, life details self-presentation, and demotivation self-presentation on SNS. Results from Experiment 1 showed that participants preferred others' life details self-presentations over positive self-presentations, and mostly disliked demotivation self-presentations. In Experiment 2, with another sample, we tested idealization, perceived interpersonal distance, stress, anxiety, and depression as mediators of participants' attitudes toward others' positive self-presentation. The results suggested that feelings of depression and interpersonal distance play a mediating role in the relationship between the self-presentation types and people's likability of these posts. The results have implications for understanding why people dislike positive self-presentations on SNS. Positive self-presentations lead people to feel more depressed and far interpersonally distanced from the sharer, and thus they are less likely to like positive self-presentation.

RESUMEN

The voice is a variable and dynamic social tool with functional relevance for self-presentation, for example, during a job interview or courtship. Talkers adjust their voices flexibly to their situational or social environment. Here, we investigated how effectively intentional voice modulations can evoke trait impressions in listeners (Experiment 1), whether these trait impressions are recognizable (Experiment 2), and whether they meaningfully influence social interactions (Experiment 3). We recorded 40 healthy adult speakers' whilst speaking neutrally and whilst producing vocal expressions of six social traits (e.g., likeability, confidence). Multivariate ratings of 40 listeners showed that vocal modulations amplified specific trait percepts (Experiments 1 and 2), which could be explained by two principal components relating to perceived affiliation and competence. Moreover, vocal modulations increased the likelihood of listeners choosing the voice to be suitable for corresponding social goals (i.e., a confident rather than likeable voice to negotiate a promotion, Experiment 3). These results indicate that talkers modulate their voice along a common trait space for social navigation. Moreover, beyond reactive voice changes, vocal behaviour can be strategically used by talkers to communicate subtle information about themselves to listeners. These findings advance our understanding of non-verbal vocal behaviour for social communication.
