The Eating Attitudes Test-26 Revisited using Exploratory Structural Equation Modeling

Most previous studies have failed to replicate the original factor structure of the 26-item version of the Eating Attitudes Test (EAT-26) among community samples of adolescents. The main objective of the present series of four studies (n?=?2178) was to revisit the factor structure of this instrument among mixed gender community samples of adolescents using both exploratory structural equation modeling (ESEM) and confirmatory factor analysis (CFA). First, results from the ESEM analyses provided satisfactory goodness-of-fit statistics and reliability coefficients for a six-factor model of the EAT with 18 items (EAT-18) closely corresponding to the original seven-factor structure proposed for the 40-item version of the EAT. Second, these analyses were satisfactorily replicated among a new sample of community adolescents using CFA. The results confirmed the factor loading and intercept invariance of this model across gender and age groups (i.e., early and late adolescence), as well as the complete invariance of the EAT-18 measurement model between ethnicities (i.e., European versus African origins) and across weight categories (i.e., underweight, normal weight and overweight). Finally, the last study provided support for convergent validity of the EAT-18 with the Eating Disorder Inventory and with instruments measuring global self-esteem, physical appearance, social physique anxiety and fear of negative appearance evaluation.     

How do job characteristics contribute to burnout? Exploring the distinct mediating roles of perceived autonomy,competence, and relatedness

This study aimed to better understand the psychological mechanisms, referred to in the job demands–resources model as the energetic and motivational processes, that can explain relationships between job demands (role overload and ambiguity), job resources (job control and social support), and burnout (emotional exhaustion, depersonalization, and personal accomplishment). Drawing on self-determination theory, we examined whether psychological resources (perceived autonomy, competence, and relatedness) act as specific mediators between particular job demands and burnout as well as between job resources and burnout. Participants were 356 school board employees. Results of the structural equation analyses provide support for our hypothesized model, which proposes that certain job demands and resources are involved in both the energetic and motivational processes—given their relationships with psychological resources—and that they distinctively predict burnout components. Implications for burnout research and management practices are discussed.     

Boosting the Potency of Resistance: Combining the Motivational Forces of Inoculation and Psychological Reactance

The efficacy of inoculation theory has been confirmed by decades of empirical research, yet optimizing its effectiveness remains a vibrant line of investigation. The present research turns to psychological reactance theory for a means of enhancing the core mechanisms of inoculation—threat and refutational preemption. Findings from a multisite study indicate reactance enhances key resistance outcomes, including: threat, anger at attack message source, negative cognitions, negative affect, anticipated threat to freedom, anticipated attack message source derogation, perceived threat to freedom, perceived attack message source derogation, and counterarguing. Most importantly, reactance‐enhanced inoculations result in lesser attitude change—the ultimate measure of resistance.     

Message size constraints on discourse planning in synchronous computer-mediated communication

Three groups of 20 dyads planned the MTV Music Video Awards Show over computers. The groups varied in whether they could send 4-line, 10-line, or 18-line messages, in part to examine whether increased planning efficiency in computer-mediated communication reflects communication strategies associated with constraints on message size. The results demonstrate that increased efficiency is not a function of such design features as the maximum message that may be sent. However, the subjects in the 4-line condition sent shorter messages to one another, were less likely to engage in a strategy of making multiple suggestions that required a single assent, and were more likely to differ in the relative proportion of their contributions to the discourse. The subjects in the 10-line condition had shorter maximum messages (and proportionately more disfluencies) than did those in the 18-line condition, despite the finding that the maximum messages of the latter would have also fit within 10 lines. Thus, the results also support a claim that size of the text window may result in different discourse management strategies and may influence an initial discourse-planning stage.
