Criterion and Incremental Validity of the MMPI-3 Eating Concerns Scale in a University Sample

The purpose of the current study was to evaluate the validity of scores on the Eating Concerns (EAT) scale on the recently released Minnesota Multiphasic Personality Inventory-3 (MMPI-3), which aims to assess for problematic eating behaviours. It was hypothesised that the EAT scale scores would be correlated with binge eating, purging, restrictive eating, weight and body shape concerns. Participants were 396 university students, who completed a series of well-validated eating disorder measures. The EAT scale scores evidenced moderate to large correlations with many symptom dimensions of EDs, including binge eating, purging, restrictive eating and weight and shape concern, thus, supporting the hypotheses and showing evidence for criterion validity. Hierarchical regression analyses also revealed incremental validity for the EAT scale above and beyond other MMPI-3 Specific Problems scale scores. Overall, scores on the new MMPI-3 EAT scale were associated with positive support for validity in a university population and seem promising as a good screening measure for eating pathology.

Skepticism,naturalism, pyrrhonism

Skepticism and naturalism bear important connections with one another. Do they conflict or are they different sides of the same coin? In this paper, by considering the ways in which Sextus and Hume have examined these issues, I offer a Pyrrhonian response to Penelope Maddy's attempt to reject skepticism within the form of naturalism that she calls “second philosophy” (Maddy, 2007, 2017) and to Timothy Williamson's attempt to avoid skepticism from emerging within his knowledge-first approach (Williamson, 2000). Some lessons about Pyrrhonism result.

Liveability Versus Sustainability in Spanish Cities: First Evidences Using Synthetic Indicators

The aim of liveable, sustainable cities has become one of the major challenges for urban planning. However, achieving both goals at the same time is no easy task, particularly when liveability and sustainability may be defined by certain elements that tend to be in conflict. The main goal of this work is to analyse the relationship between liveability and environmental sustainability within the context of Spanish urban spaces. To this end, we propose two synthetic indicators: one for liveability and the other for urban environmental sustainability. Each of these indicators is constructed using a technique based on goal programming. A bivariate analysis is carried out using these indicators, which allows us to compare the extent to which Spanish cities are liveable and sustainable. This analysis should be useful for urban planners when taking and implementing policy decisions. By comparing cities with similar profiles using a benchmarking system, it becomes possible to judge the margin for improvement in one attribute without detriment to the other. This benchmarking system also allows us to reveal the specific dimensions of liveability or sustainability for which there is the greatest opportunity for improvement.

     

Gender Differences in Psychological Well-Being in Emerging Adulthood

Gender is recognized as an important social determinant of health, but past research on gender differences in psychological well-being have not produced conclusive results. This study investigated gender differences in eudaimonic well-being and life satisfaction in emerging adulthood. A cross-sectional study with a sample of 1990 emerging adults (50% males) from the Spanish general population was conducted. Participants were assessed through five questionnaires. Results showed that women scored higher than men in purpose in life and personal growth. Hierarchical multiple regression analysis revealed that the most important predictors of emerging adult men’s and women’s eudaimonic well-being and life satisfaction were higher self-confidence and lower negative self-evaluation. Other significant variables in the eudaimonic well-being of both women and men were higher score in the masculine/instrumental trait, higher emotional social support, higher educational level, and higher score in the feminine/expressive trait. Furthermore, higher instrumental social support was associated with eudaimonic well-being in females. Other predictors of women’s and men’s life satisfaction were higher score in the feminine/expressive trait, less age, higher educational level and higher instrumental social support. In addition, higher emotional social support was associated with life satisfaction in males. The results suggest that gender is important in the psychological well-being of people in emerging adulthood, although self-esteem and instrumental social support are, in both emerging adult women and men, the most important predictors of psychological well-being.

     

Estimation of the predictive power of the model in mixed‐effects meta‐regression: A simulation study

Several methods are available to estimate the total and residual amount of heterogeneity in meta‐analysis, leading to different alternatives when estimating the predictive power in mixed‐effects meta‐regression models using the formula proposed by Raudenbush (1994, 2009). In this paper, a simulation study was conducted to compare the performance of seven estimators of these parameters under various realistic scenarios in psychology and related fields. Our results suggest that the number of studies (k) exerts the most important influence on the accuracy of the results, and that precise estimates of the heterogeneity variances and the model predictive power can only be expected with at least 20 and 40 studies, respectively. Increases in the average within‐study sample size () also improved the results for all estimators. Some differences among the accuracy of the estimators were observed, especially under adverse (small k and ) conditions, while the results for the different methods tended to convergence for more optimal scenarios.
