The interaction of perfectionism, perceived weight status, and self-esteem to predict bulimic symptoms: the role of 'benign' perfectionism

The present study sought to replicate an interactive model of global perfectionism, perceived weight status, and self-esteem in predicting bulimic symptom development in a sample of young women [Bardone-Cone, et al. (2006). Predicting bulimic symptoms: An interactive model of self-efficacy, perfectionism, and perceived weight status. Behaviour Research and Therapy, 44, 27-42; Vohs, K. D., et al. (1999). Perfectionism, perceived weight status, and self-esteem interact to predict bulimic symptoms: A model of bulimic symptom development. Journal of Abnormal Psychology, 108, 695-700; Vohs, K. D., et al. (2001). Perfectionism, body dissatisfaction, and self-esteem: An interactive model of bulimic symptom development. Journal of Social and Clinical Psychology, 20, 476-497]. The aim was to investigate the role of 'problematic' and 'benign' perfectionism within this model, using data from 95 female university students over a 3-month period. Contrary to hypotheses, multivariate analyses revealed a significant three-way interaction only between 'benign' perfectionism, perceived weight status and self-esteem in predicting change in bulimic symptoms over a 3-month period. The predictive effect of the interaction between 'benign' perfectionism and perceived weight status on bulimic symptoms was strongest for women with high self-esteem, for whom feeling overweight and having perfectionistic attitudes preceded increased bulimic symptoms. These findings suggest that high self-esteem is insufficient to protect against the development of bulimic symptoms when both the perception of oneself as being overweight, and high levels of perfectionistic standards, are present. It would appear that the role of perfectionism within the context of disordered eating is complex.     

A Psychometric Review of the Personality Inventory for DSM–5 (PID–5): Current Status and Future Directions

The paradigm of personality psychopathology is shifting from one that is purely categorical in nature to one grounded in dimensional individual differences. Section III (Emerging Measures and Models) of the Diagnostic and Statistical Manual of Mental Disorders (5th ed. [DSM–5]; American Psychiatric Association, 2013), for example, includes a hybrid categorical/dimensional model of personality disorder classification. To inform the hybrid model, the DSM–5 Personality and Personality Disorders Work Group developed a self-report instrument to assess pathological personality traits—the Personality Inventory for the DSM–5 (PID–5). Since its recent introduction, 30 papers (39 samples) have been published examining various aspects of its psychometric properties. In this article, we review the psychometric characteristics of the PID–5 using the Standards for Educational and Psychological Testing as our framework. The PID–5 demonstrates adequate psychometric properties, including a replicable factor structure, convergence with existing personality instruments, and expected associations with broadly conceptualized clinical constructs. More research is needed with specific consideration to clinical utility, additional forms of reliability and validity, relations with psychopathological personality traits using clinical samples, alternative methods of criterion validation, effective employment of cut scores, and the inclusion of validity scales to propel this movement forward.     

Young emerging adults’ graduateness and career adaptability: Exploring the moderating role of self-esteem

This study investigated the moderating role of self-esteem on young emerging adults’ in their school-to-work transition phase of graduateness skills and career adaptability. A non-probability convenience sample (n=332) of undergraduate black (98.5%) and female (62%) young emerging adults (18–29 years) at a Further Education and Training (FET) college in South Africa participated in the study. Participants completed the Culture Free Self-esteem Inventory for Adults (CFSEI 2-AD, Battle, 1992 Battle, J. (1992). Culture-free self-esteem inventories for children and adults. Texas: Pro-Ed. [Google Scholar]), the Graduateness Skills and Attributes Scale (GSAS, Coetzee, 2010 Coetzee, M. (2010). Exploratory Factor Analyses of the Graduateness Scale and the Employability Attributes Scale. Pretoria: Unpublished research report. University of South Africa. [Google Scholar]) and the Career Adapt-abilities Scale (CAAS, Savickas &; Porfeli, 2012 Savickas, M. L., &; Porfeli, E. J. (2012). Career Adapt-Abilities Scale: Construction, reliability and measurement equivalence across 13 countries. Journal of Vocational Behavior, 80(3), 674–679. doi: 10.1016/j.jvb.2012.01.011[Crossref], [Web of Science ®] , [Google Scholar]). Hierarchical moderated regression analysis indicated significant interaction effects between self-esteem and overall graduateness, lifelong learning and global/moral citizenship skills and attributes in moderating overall career adaptability. The relationship between the participants’ graduateness skills and attributes (overall graduateness, global/moral citizenship, and lifelong learning) and their career adaptability was significantly stronger when their self-esteem was high than when their self-esteem was low. The finding suggests self-esteem to influence self-perceived graduateness skills and career adaptability in emerging adults.     

Identity and Intimacy Development,Humor Styles,and Psychological Well-Being

This study explored how humor may be involved in the identity and intimacy stages of Erikson’s psychosocial model and also bear on psychological well-being. Participants completed measures of identity and intimacy development, several humor styles, and psychological well-being. Findings revealed that greater identity development was associated with more self-enhancing and affiliative humor use and less self-defeating humor use. Greater intimacy, in turn, was associated with higher affiliative humor and lower self-defeating humor use. Additional findings indicated that the prediction of psychological well-being was significantly enhanced when identity, intimacy, and humor styles were all taken into account. These findings were then considered in terms of specifying the underlying processes that may account for the observed links between identity, intimacy, humor styles, and well-being.     

Students’ Responses to Improve Environmental Sustainability Through Recycling: Quantitatively Improving Qualitative Model

This study attempts to contemplate the respondents’ behaviors regarding recycling, with the purpose of identifying the factors that influence their behaviors. The study is based on a survey that was conducted with 230 nationwide university students and guidelines borrowed from the Theory of Planned Behavior and The Theory of Reasoned action. The data collected was evaluated by applying the Structure Equation Modelling technique. The study concluded that peoples’ attitudes are largely subject to the moral values and general norms of their own society. Additionally, an individual’s response towards recycling is greatly determined by the extent of his/her awareness towards the environment, as well as his/her personal knowledge. Another conclusion was that an individual’s past experience towards recycling contributes to his/her attitude (willingness or apprehension about recycling) in the future. Furthermore, although the convenience and cost of recycling were found to be reasonably significant determinants about one’s recycling behavior, it was determined that time commitment is the most decisive factor that influences an individual’s willingness to or not to recycle. The study’s findings have not only established the authority of Theory of Planned Behaviour and Theory of Reasoned Action, but it has also presented propositions and recommendations for future research. The inferences were based on the study’s respondents, hence, so their validity can be applied to various scenarios involving local educational institutions or government structures. The goal of the study is to encourage people to engage in positive recycling behavior.     

Le contentieux de la régularité externe des décisions rendues par les juridictions ordinales des médecins

In the event of irregular composition of the ordinal jurisdiction or omission of certain compulsory particulars in the decision rendered, the parties may challenge the external regularity of the decision. The pleas based on the contested decisions are formal and procedural defects. If successful, these means result in the annulment of the decision ordering the doctor to be disciplined. These means constitute a separated legal cause and can only be invoked within the time limit for appeal, unless they are of public order.     

Memory traces compete under regimes of limited Arc protein synthesis: Implications for memory interference

Recently encoded information can be lost in the presence of new information, a process called 'retrograde interference'. Retrograde interference has been extensively described for more than a century; however, little is known about its underlying mechanisms. Different approaches agree on the need of the synthesis of plasticity related proteins (PRPs) to consolidate a long-term memory (LTM). Our hypothesis is that when PRPs are limited, interference of a task over LTM formation of another may be due to the utilization of protein resources common to both tasks. Here, by combining the tasks of inhibitory avoidance (IA) and open field (OF) exploration in rats, we show that memory traces compete for their stabilization if PRPs are limited. As a result, LTM is formed for only one of the tasks with a consequent decrease in the memory for the other. Furthermore, infusing Arc antisense oligonucleotide into the dorsal hippocampus, we found that Arc is necessary for LTM formation of these two types of learning tasks and is one of the PRPs that can be shared between them when animals are trained in both OF and IA. In sum, these findings suggest that under conditions of reduced protein availability, a learning task interferes with LTM formation of another by using the available PRPs.     

The early development of human mirror mechanisms: evidence from electromyographic recordings at 3 and 6 months

In primates and adult humans direct understanding of others' action is provided by mirror mechanisms matching action observation and action execution (e.g. Casile, Caggiano & Ferrari, 2011). Despite the growing body of evidence detailing the existence of these mechanisms in the adult human brain, their origins and early development are largely unknown. In this study, for the first time, electromyographic (EMG) measures were used to shed light on the emergence of mirror motor mechanisms in infancy. EMG activity was recorded while 6‐ and 3‐month‐old infants watched two videos displaying an agent reaching for, grasping and bringing an object either to the mouth or to the head. Results indicate that the motor system of 6‐month‐olds, but not 3‐month‐olds, was recruited and selectively modulated during observation of the goal‐directed actions, favoring the idea that mirror mechanisms driving action understanding gradually emerge during early development.     

Differential Memory Test Sensitivity for Diagnosing Amnestic Mild Cognitive Impairment and Predicting Conversion to Alzheimer's Disease

ABSTRACT

Episodic memory is the first and most severely affected cognitive domain in Alzheimer's disease (AD), and it is also the key early marker in prodromal stages including amnestic mild cognitive impairment (MCI). The relative ability of memory tests to discriminate between MCI and normal aging has not been well characterized. We compared the classification value of widely used verbal memory tests in distinguishing healthy older adults (n = 51) from those with MCI (n = 38). Univariate logistic regression indicated that the total learning score from the California Verbal Learning Test-II (CVLT-II) ranked highest in terms of distinguishing MCI from normal aging (sensitivity = 90.2; specificity = 84.2). Inclusion of the delayed recall condition of a story memory task (i.e., WMS-III Logical Memory, Story A) enhanced the overall accuracy of classification (sensitivity = 92.2; specificity = 94.7). Combining Logical Memory recognition and CVLT-II long delay best predicted progression from MCI to AD over a 4-year period (accurate classification = 87.5%). Learning across multiple trials may provide the most sensitive index for initial diagnosis of MCI, but inclusion of additional variables may enhance overall accuracy and may represent the optimal strategy for identifying individuals most likely to progress to dementia.     

Measuring Optimism in Organizations: Development of a Workplace Explanatory Style Questionnaire

Some researchers measure optimism by analysing explanations for hypothetical scenarios in explanatory style questionnaires. The most commonly used instrument, the Attributional Style Questionnaire (ASQ), has been shown to predict success in business, education and sport. However, these predictions were achieved by using composite scores of subscales. Our analysis of 15 measures revealed the ASQ and many other explanatory style questionnaires have low internal consistency. Furthermore, the majority of these measures use situations that have poor face validity for corporate applications, while some work-specific scenarios are only relevant to narrow domains such as selling insurance. To fulfil the need for a work-related explanatory style measure that could assess levels of optimism in any organizational setting, we developed the Workplace Explanations Survey (WES). This 5-factor measure was tested on a sample of 341 individuals working in a range of organizations and it has good internal consistency. We anticipate the WES will stimulate research into workplace optimism and provide clearer insights for optimism training, thus boosting both individual and organizational success.
