The aim of the study is to present a model of measuring the quality of market information as a second-order factor model. To receive this model the confirmatory factor analysis (CFA) was used. The rationale for creating the second-order model was high correlation of the four originally assumed factors in the first-order measuremment model as well as substantive reasons. The first-order factors under consideration were reliability, completeness, relevance, and timeliness of information. The study used orginal data of new product projects in which we measured reliability, completeness, usefulness and timeliness of the information available in the new product development. The sample was randomly selected from the national population of high and medium-high technology firms, employing more than 49 people. We received a second-order general factor – quality of the information – that explained the high correlation among the four first-order factors. The resulting model had an acceptable level of data fit and relevant and high factor loadings for both, first and second order models.

The purpose of this study was to test the validity and reliability of the “Short Flow State Scale-2 (SFSS-2)” and “Short Dispositional Flow Scale-2 (SDFS-2)” for Turkish athletes in two separate studies. One hundred ninety-seven athletes (Mage = 22.05, SD = 3.60) voluntarily participated in the first study to test the psychometric properties of SDFS-2 and completed SDFS-2, Long Dispositional Flow Scale-2, and Sport Motivation Scale. In the second study, 423 athletes (Mage = 20.00, SD = 3.46) constituted the sample group and completed SFSS-2, Flow State Scale2, and Situational Motivation Scale for testing the psychometric properties of SFSS-2. Factor structures of both scales were examined by confirmatory factor analysis (CFA). Concurrent validity of the scales was examined by Pearson Product Moment Correlation analysis. The reliability evidence was obtained by a Cronbach’s alpha values. The results of CFA from both studies revealed that both scales have nine items with one factor. All the correlation coefficients calculated for concurrent and convergent validity were significant (between 0.45-0.92 for SDFS-2 and 0.33-0.79 for SFSS-2). Cronbach’s alpha coefficients calculated for internal consistency were 0.77 for SDFS-2 and 0.82 for SFSS-2. The results from both studies indicated that Turkish versions of SDFS-2 and SFSS-2 are valid and reliable instruments to be used in sports contexts.

On an enormous field of Africa, composed of different countries, sometimes outlying, money circulates, franc CFA, which is not under the control of political units, called independent states. This monetary area is called zone of franc. It connects former French colonies of West Africa, Central Africa and Indian Ocean. Some call this situation monetary neocolonialism. So, it is possible to put question if countries of franc's zone are sovereign, as that they do not have capabilities of beating their own coins, a political act, lack of which pulls down the bases of their sovereignty. These countries have still common currency imposed in the colonial period. The history of CFA is strictly correlated with the history of colonization of African countries CFA. Franc CFA has emerged 25 December 1945 officially, the day, that France ratified Bretton Woods Agreements. The creation of franc CFA was and remains still reasonable for French authorities, for the reason of particular co-operation between France and its old colonies. There was a delicate manner to control the economy of these African countries also. In fact, since colonization, African countries remain stocks of raw materials and had to supply French industry, when France transfers to these countries its surplus of industrial production. This way, franc CFA enabled the transfer of French firms benefices without risk of exchange rate.

Work engagement as a predictor of health is an emerging concept in occupational science and the Utrecht Work Engagement Scale (UWES) is the most popular work engagement measurement tool. However, despite its popularity, the UWES is not free from controversy concerning its factorial validity. In this paper, 21 research studies on both UWES-9 and UWES-17 factorial validity within the confirmatory factor analysis (CFA) approach have been reviewed in order to answer the question as to which of the UWES factorial structures displays greater validity. The originally proposed threefactor structure of the UWES has been recognized as superior in 6 studies. In further 6 studies, the UWES structure with 1 general factor has been found to be superior. In 8 studies, the authors have concluded that the one- and three-factor structures could be considered equivalent. One study has failed to confirm either the one- or three-factor structure of the UWES. These ambiguous results from studies focusing on the UWES factorial validity are puzzling because they not only indicate a lack of validity for the UWES as a measurement tool but might also challenge the whole concept of work engagement as a three-factor structure of dedication, vigor and absorption.

The replication study offers research findings from verification of the construct validity of social intelligence by the Slovak MESI scale (Manipulation, Empathy, Social Irritability - MESI, Frankovský, Birknerová, 2014) by means of confirmatory factor analysis, and by convergent/discriminant validity by the trait emotional intelligence questionnaire (Petrides, 2009) in two samples (secondary school students: N = 134, Mage = 17.7 years old /SD = 0.47/, 66% women; university students: N = 138, Mage = 21.52 years old /SD = 1.81/, 77% women). Results of confirmatory factor analysis (CFA) confirm the three-factor solution of the MESI scale (extracted factors of Manipulation, Empathy, Social Irritability) in accordance with the authors’ original solution in both samples. Trait emotional intelligence (EI) and its four factors enter into significant positive relationships with Empathy (convergent validity) and negative relationships with Social Irritability (discriminant validity). The global level of trait EI can be predicted by the factor of Empathy and Social Irritability in both research samples. Our findings confirm substantiation of the MESI scale for assessment of social intelligence, and its possible application in targeted educational interventions in a school environment.

The goal of this paper is the reanalysis of the Czech “Assessment of the structure of mathematical abilities” test (Traspe and Skalková, 2013), designed to assess problems related to the development of mathematical abilities in children aged approx. 5–11 years. The test contains 14 developmental scales and total scores – a total of 22 test scores with percentile norms. This study uses normative (N = 878) and clinical (N = 877) samples and focuses on three objectives: (1.) the estimation of composite scores reliability using stratified Cronbach's alpha; assessment of content validity and test fairness using (2.) a series of confirmatory factor analyses and (3.) differential item functioning analysis (DIF). Reliability estimates, which took into account the multidimensional structure of composite scores, led to a two-fold (in the case of total score, a three-fold) decrease in standard errors and narrower confidence intervals. Structural models supported the assumption of a weak factorial invariance between grades 2 to 5, except the Computing Automation subtest (the relationship of which with overall math ability strengthens with age). However, the factorial structures for first graders and younger children were different and there was no clear factor structure in the clinical sample. Results also suggested that the Mathematical Ideas subtest can serve as a screening method of the overall level of mathematical abilities. Single scales were not shown to be invariant according to the DIF analyses between grades and samples, which might mean that lower scores do not simply imply lower levels of mathematical ability, but also qualitative differences. This paper offers further recommendations for test use in common assessment situations.

Cílem textu je reanalýza testu Diagnostika struktury matematických schopností (Traspe a Skalková, 2013), který slouží k zjišťování obtíží v rozvoji matematických schopností u dětí ve věkovém rozmezí od doby těsně před nástupem do základní školy až do pátého ročníku. Test obsahuje 14 vývojových škál a celkové skóry, celkem je k dispozici 22 škál s percentilovými normami. Tato studie pracuje se standardizačním (N = 878) a poradenským (N = 877) vzorkem a zaměřuje se na tři hlavní témata: (1.) ověření reliability součtových skórů prostřednictvím stratifikovaného Cronbachovo alfa, ověření obsahové validity testu a jeho férovosti pomocí (2.) série konfirmačních faktorových analýz a (3.) analýzy diferenciálního fungování položek (DIF). Odhady reliability se zohledněním vícedimenzionální struktury součtových skórů docílily až dvakrát (v případě celkového skóre až třikrát) menších standardních chyb měření a tedy i intervalů spolehlivosti. Strukturní modely podpořily předpoklad slabé faktorové invariance u dětí v 2.–5. ročníku ZŠ vyjma subtestu automatizace početních dovedností (jehož vztah s celkovými matematickými schopnostmi vzrůstá spolu s věkem dětí), faktorová struktura pro žáky prvních tříd a předškolní děti je nicméně odlišná a v poradenské populaci pak nelze identifikovat žádné stabilní faktory. Ukázalo se ale také, že subtest matematické pojmy lze samostatně použít u běžné populace pro kratší skríning celkové úrovně matematických schopností. Jednotlivé škály se pak během analýzy DIF ukázaly být ne zcela invariantní napříč ročníky i oběma vzorky: zdá se tedy, že nižší skóre v testu nemusí znamenat jen „kvantitativně nižší“ míru schopností v příslušných rysech, ale do jisté míry též kvalitativní odlišnosti od běžné populace. Článek poskytuje konkrétní doporučení pro další používání testu v běžné diagnostické praxi.
