Cognitive Dissonance in the Self-assessed Health in Brazil: A CUB Model Analysis Using 2013 National Health Survey Data

This study ai ms to verify and analyze the existence of cognitive dissonance in the self-assessment of health by individuals in Brazil, that is, the difference between self-rated health and the health status of individuals. To accomplish this, we use data from the 2013 National Health Survey, which collected the self-assessments that individuals made of their health and information about their health status. This information was used to build indices that seek to represent a person's health status in relation to chronic illnesses, physical and mental well-being, eating habits and lifestyle. To identify the presence of cognitive dissonance, the CUB (Combination of a discrete Uniform and shifted Binomial distributions) model was used, which relates self-assessed health with the developed indices. Cognitive dissonance was identified in self-assessed health in relation to eating habits and lifestyle, and this dissonance may be associated with a present bias in the self-assessment of health in Brazil.

Behavioral Responses to Losses Disguised as Wins: A Field Study of Slot Machine Players

We present the results of a field study examining the effect of losses disguised as wins (LDWs) on subsequent slot machine gambler betting behavior. An LDW occurs when the amount won is less than the amount bet. Using non-experimental, individual transaction gambling data, we examine post LDW betting behavior in a panel of 42,669 gamblers and 17 million slot machine plays. The primary empirical findings include: (1) streaks of three LDWs greater than 75% of the original amount bet lead slot gamblers to increase the amount bet on the next spin; (2) streaks of three LDWs less than 25% of the original amount bet results in gamblers decreasing their bet size on the next spin; (3) slot machine gamblers play faster following streaks of three LDWs compared to losses. We interpret these behavioral findings of differing outcomes associated with small versus large LDWs as consistent with a cognitive dissonance effect (Festinger, 1957). Specifically, the disconnect between the amount "won" (actually lost) and the audio and video stimulus produced by the slot machine highlighting the LDW, produces a dissonance-related arousal that players seek to avoid or reduce leading to changes in betting behavior. Our results complement the experimental findings on LDWs and suggest that the size of the LDW matters in examining the impact on gambling behavior.

Prevention of eating disorders in argentine adolescents

In the last few decades much effort has been devoted to developing prevention programs for eating disorders, as most individuals with these pathologies do not receive treatment and tend to become chronic. The purpose of this study was to evaluate a cognitive dissonance and media literacy intervention aimed at preventing eating disorders in female adolescents. Eighty-eight female students (aged 12-17) from Argentina, participated in a 3-session program. Adolescents completed a baseline, post-intervention and a 6-month follow-up survey. A significant decrease in thin-ideal internalization, body image concerns, influence of advertising, drive for thinness and bulimic attitudes was found at post-intervention. In addition, the number of participants with disturbed eating attitudes and behaviors decreased at post-intervention. Results for body image concerns and drive for thinness were maintained at follow-up.

Screening of Potential Genes and Transcription Factors of Postoperative Cognitive Dysfunction via Bioinformatics Methods

Background

The aim of this study was to explore the potential genes and transcription factors involved in postoperative cognitive dysfunction (POCD) via bioinformatics analysis.

Material/Methods

GSE95070 miRNA expression profiles were downloaded from Gene Expression Omnibus database, which included five hippocampal tissues from POCD mice and controls. Moreover, the differentially expressed miRNAs (DEMs) between the two groups were identified. In addition, the target genes of DEMs were predicted using Targetscan 7.1, followed by protein-protein interaction (PPI) network construction, functional enrichment analysis, pathway analysis, and prediction of transcription factors (TFs) targeting the potential targets.

Results

A total of eight DEMs were obtained, and 823 target genes were predicted, including 170 POCD-associated genes. Furthermore, potential key genes in the network were remarkably enriched in focal adhesion, protein digestion and absorption, ECM-receptor interaction, and Wnt and MAPK signaling pathways.

Conclusions

Most potential target genes were involved in the regulation of TFs, including LEF1, SP1, and AP4, which may exert strong impact on the development of POCD.

A Curriculum for Clerkship Students to Foster Professionalism Through Reflective Practice and Identity Formation

INTRODUCTION

Research suggests that students become less patient-centered and empathetic in response to both internal and external factors, including the organizational culture, or hidden curriculum, of medical school. Students often feel compelled to make compromises when they experience tension between competing values in clinical teaching environments. To address this, we implemented a modular, longitudinal professionalism curriculum for third-year medical students, based on a conceptual model that highlights a student's ideal, as well as the internal and environmental forces that can either sustain or change their ideal over time.

METHODS

As students progressed through the third year, they participated in various modules linked to different clerkships, each focusing on a different aspect of the conceptual model. Each module includes a reflective writing exercise followed by a faculty-facilitated discussion.

RESULTS

In general, students rated the group discussions and faculty facilitation as the most useful parts of each session and the writing exercises as the least useful. Written comments were mostly favorable and suggested that the session facilitated self-reflection and provided a safe environment for students to discuss stressors of third-year clerkships.

DISCUSSION

This curriculum represents a unique approach to fostering professional role formation through its broad potential applicability to multiple types and levels of learners, its adaptability to fit various course lengths and learning environments, and its incorporation of a conceptual model that allows individual learners to address different facets of the sustaining and acculturating forces that impact their personal professional identity formation for future encounters.

Peer Rejection as a Social Antecedent to Rejection Sensitivity in Youth: The Role of Relational Valuation

Although much is known about the consequences of rejection sensitivity (RS), less is known about its social antecedents, particularly during development. Despite research demonstrating the role of peer rejection in the development and maintenance of problematic social schema like RS, little is known about why some youth are more susceptible to these negative consequences than others. We examined how relational valuation might moderate the effects of peer rejection on RS in a sample of 294 youth (138 boys) who made the transition from middle to high school. Results from path analysis revealed that 8^th grade peer rejection was most highly associated with 9^th grade RS for youth who held high regard for social relationships. Findings demonstrate the importance of examining cognitive moderators in the links between negative social experiences and problematic social schema, and highlight the need to move beyond simple main effects models for understanding the heterogeneity of rejection.
