Psychometric characteristics of the Emotional Quotient Inventory, Youth Version, Short Form, in Hungarian high school students

Research on the psychometric characteristics, including factor structure, of measures assessing emotional intelligence improve our understanding of the manifest and latent dimensions of the construct. The factor structure of the Bar-On Emotional Quotient Inventory (Bar-On, 1997), despite the popularity of the measure, has been the subject of only a few studies, and there are no data available at all on its 30-item version. The aim of our study was the structural analysis of the Bar-On Emotional Quotient Inventory, Youth Version, Short Form (Bar-On & Parker, 2000). During the multiple-step statistical analysis, confirmatory and exploratory factor analyses and a combined method of these were executed on a sample of 2,380 adolescents (mean age: 17 years, 47.9 % male). The results confirmed the original 5-factor structure (Intrapersonal Emotional Quotient, Interpersonal Emotional Quotient, Stress Management, Adaptability, and Positive Impression). However, only 24 of the original 30 items could be considered as belonging to the scales. Elimination of 6 items resulted in a clearer and more coherent factorial structure, which makes the measure an adequate tool for the assessment of the emotional intelligence of adolescents and young adults in surveys of large-scale samples.     

Psychometric properties and concurrent validity of two exercise addiction measures: A population wide study

ObjectivesThe existence of exercise addiction has been examined in numerous studies. However, none of the measures developed for exercise addiction assessment have been validated on representative samples. Furthermore, estimates of exercise addiction prevalence in the general population are not available. The objective of the present study was to validate the Exercise Addiction Inventory (EAI; Terry, Szabo, & Griffiths, 2004), and the Exercise Dependence Scale (EDS; Hausenblas & Downs, 2002b), and to estimate the prevalence of exercise addiction in general population.DesignExercise addiction was assessed within the framework of the National Survey on Addiction Problems in Hungary (NSAPH), a national representative study for the population aged 18–64 years (N = 2710).Method474 people in the sample (57% males; mean age 33.2 years) who reported to exercise at least once a week were asked to complete the two questionnaires (EAI, EDS).ResultsConfirmatory Factor Analysis (CFA) indicated good fit both in the case of EAI (CFI = 0.971; TLI = 0.952; RMSEA = 0.052) and EDS (CFI = 0.938; TLI = 0.922; RMSEA = 0.049); and confirmed the factor structure of the two scales. The correlation between the two measures was high (r = 0.79). Results showed that 6.2% (EDS) and 10.1% (EAI) of the population were characterized as nondependent-symptomatic exercisers, while the proportion of the at-risk exercisers were 0.3% and 0.5%, respectively.ConclusionsBoth EAI and EDS proved to be a reliable assessment tool for exercise addiction, a phenomenon that is present in the 0.3–0.5% of the adult general population.     

Processing negative numbers by transforming negatives to positive range and by sign shortcut

Numerals are processed by a phylogenetically old analogue magnitude system. Can culturally new negative numerals be processed using this same representation? To find out whether magnitude representation could be used, we contrasted three possible processing mechanisms: an extended magnitude system for both positive and negative numbers, a mirroring mechanism that could transform negative values to the positive range to be processed on the positive magnitude system, and a sign shortcut strategy that can process the signs of numbers independently of the absolute values of numerals. To test these three hypotheses, a comparison task was used and the reaction time pattern, numerical distance, and Spatial-Numerical Association of Response Codes (SNARC) effect was analysed. The results revealed a mirroring process along with a sign shortcut mechanism. The SNARC effect was observed only when positive numbers were compared.     

Multi-Dimensional Consequentialism and Risk

In his new book, The Dimensions of Consequentialism, Martin Peterson proposes a version of multi-dimensional consequentialism according to which risk is one among several dimensions. We argue that Peterson’s treatment of risk is unsatisfactory. More precisely, we discuss a number of major problems of one-dimensional (objective or subjective) consequentialism, and show that none of them disappears with Peterson’s proposal. In ending our paper, we address the objection that our discussion overlooks the fact that Peterson’s proposal is not the best version of multi-dimensional consequentialism. Our reply is that the possibilities of improving multi-dimensional consequentialism are very limited as far as risk is concerned.     

Positivity is an up‐to‐date predictor of well‐functioning instead of a eudaemon

Summing up the process of conceptualization of positive orientation theory (POT), the results of empirical studies which confirmed its validity, the operationalization of the positive orientation as a personality disposition in the Positivity Scale (PS), and the verification of the scale responsibility and empirical validity, it can be established that POT is a very promising, empirically validated theory. The dissemination of the POT and the PS in high‐impact scientific journals is an important contribution to the research on well‐being and in the domains of health psychology and positive psychology as well.     

Transfer of movement sequences: bigger is better

Experiment 1 was conducted to determine if proportional transfer from "small to large" scale movements is as effective as transferring from "large to small." We hypothesize that the learning of larger scale movement will require the participant to learn to manage the generation, storage, and dissipation of forces better than when practicing smaller scale movements. Thus, we predict an advantage for transfer of larger scale movements to smaller scale movements relative to transfer from smaller to larger scale movements. Experiment 2 was conducted to determine if adding a load to a smaller scale movement would enhance later transfer to a larger scale movement sequence. It was hypothesized that the added load would require the participants to consider the dynamics of the movement to a greater extent than without the load. The results replicated earlier findings of effective transfer from large to small movements, but consistent with our hypothesis, transfer was less effective from small to large (Experiment 1). However, when a load was added during acquisition transfer from small to large was enhanced even though the load was removed during the transfer test. These results are consistent with the notion that the transfer asymmetry noted in Experiment 1 was due to factors related to movement dynamics that were enhanced during practice of the larger scale movement sequence, but not during the practice of the smaller scale movement sequence. The findings that the movement structure is unaffected by transfer direction but the movement dynamics are influenced by transfer direction is consistent with hierarchal models of sequence production.     

The relationship of impairment to personality disorder severity among individuals with specific axis I disorders: results from the National Epidemiologic Survey on Alcohol and Related Conditions

The present study examined one dimensional approach to personality disorders (PDs) in a large (n = 43,093), nationally representative sample of the U.S. population. Respondents were classified in four personality severity categories (no PD, subthreshold PD, simple PD, complex PD). Linear regression analyses were conducted to examine mental disability by PD severity for major DSM-IV substance use, mood and anxiety disorders. Significant increases in disability were observed between no PD and simple PD and between simple PD and complex PD for each Axis I disorder except drug dependence, but few differences in disability were found between no PD and subthreshold PD. This study found support for the clinical utility of the dimensional classification of PD severity with regard to the distinction between simple and complex PD and for a combined no PD-subthreshold PD level of severity. Future planned analyses will address the clinical utility of the classification prospectively, with a full battery of all Axis II PDs.     

Psychometric properties of the Hamilton Depression Rating Scale and other physician-rated psychiatric scales for the assessment of depression in ESRD patients undergoing hemodialysis in Turkey

This study aimed to examine the reliability and validity of clinician-rated psychiatric scales for end-stage renal disease (ESRD) patients undergoing hemodialysis (HD) treatment in Turkey. For this, the Hamilton Depression Rating Scale (HDRS), Hamilton Anxiety Rating Scale (HARS), Global Assessment of Functioning (GAF) Scale, Clinical Global Impression (CGI) Scale, and Mini Mental State Exam (MMSE) were administered to 45 ESRD outpatients undergoing HD treatment. Regarding the reliability of HDRS and HARS, internal consistency and split-half reliability analyses revealed acceptable coefficients. The test - retest reliability coefficients were also examined for all measures after a period of a month, and despite this relatively long time interval, test - retest reliability coefficients were above .60 for all measures. Concerning the validity studies, all these scales revealed suitable convergent, discriminant, and criterion validity outcomes. A cut-off point of 10 for HDRS is suggested for the identification of depression in this population. In general, the findings of this study indicate that HDRS, HARS, CGI, GAF, and MMSE are reliable and valid instruments that can be used among ESRD patients undergoing HD.     

Representation of movement sequences is related to task characteristics

Recent experiments have produced mixed results in terms of performance when, after learning a sequential task, the same visual-spatial coordinates or the same motor coordinates were reinstated on a subsequent effector transfer test. Given the diversity of tasks and especially sequence characteristics used in previous experiments, the cross-experimental comparison makes inferences and unambiguous interpretations difficult. The purpose of the present experiment was to determine in a principled manner how the spatio-temporal structure of a sequence influences the way the sequence is represented. The results indicated that after limited amount of practice relatively more simple sequences (S1) are coded more efficiently in a mirror (motor) representation which requires the same pattern of homologous muscle activation. Conversely, relatively more complex sequences (S2) are more efficiently coded in a visual-spatial coordinate system which requires movements to the same spatial locations as during acquisition. The data are also consistent with the notion that sequences with different spatio-temporal structures rely to a different degree on distinct control mechanisms (pre-planned vs. on-line, respectively).
