bjectives. The aim of the study was to assess psychometric properties, validity and internal consistency of the Slovak version of the Proactive Coping Inventory (PCI). The article deals with: a) factorial structure of the PCI, b) item analysis and internal consistency of its scales, c) discriminant validity. Subjects and settings. The sample consisted of employed adult people from all main regions in Slovakia, 22% were men and 78% women. Their age ranged from 20 to 60 years, with mean age 38.62 (SD=10.78). Statistical analysis. Confirmatory factor analysis was used to test the models, Maximum Likelihood (ML) method, the goodness of fit indexes: χ2 test, χ2/df, RMSEA, 90% CI for RMSEA, CFI, GFI, and information criteria AIC, BIC. Item analysis was conducted by descriptive characteristics and popularity index p. Internal consistency was assessed by coefficients α and ω, statistical relationships were tested using Pearson’s correlation coefficient. Results. None of the presented models (seven, three and one factor models) fits the data well. Modified one-factor models fit the data well. Internal consistency is low in all scales (α=ω=.55-.78). Item analysis identified several problematic items. There are significant relationships between the PCI scales. The results open the space for discussion, whether the problem is affected mainly by translation or if it corresponds with the original scale construction. The current studied Slovak version of the PCI does not meet required psychometric properties and several further modifications are needed: to improve the fit of multifactor models of the PCI and significantly increase the internal consistency of the PCI. Study limitations. The sample is not representative due to nonprobabilistic sampling method and higher percentage of women. The exploratory character of the PCI models modifications is also considered as a study limit.

Zámer. Cieľom štúdie bolo posúdenie psychometrických vlastností, validity a vnútornej konzistencie slovenskej verzie dotazníka PCI. Štúdia sa zaoberá a) skúmaním faktorovej štruktúry dotazníka PCI, b) skúmaním položkovej analýzy a vnútornej konzistencie škál PCI a c) diskriminačnou validitou. Súbor a procedúra. Súbor tvorili dospelí zamestnaní participanti (n = 540) so zastúpením všetkých krajov na Slovensku, z toho 22 % mužov a 78 % žien. Vekové rozloženie bolo v rozpätí od 20 do 60 rokov, s priemerným vekom 38,62 (SD = 10,78). Štatistická analýza. Modely boli hodnotené pomocou konfirmačnej faktorovej analýzy, metódou Maximum likelihood (ML), indexami zhody: χ2 test, χ2/df, RMSEA, 90% CI pre RMSEA, CFI, GFI, a informačnými kritériami AIC, BIC. Položková analýza bola realizovaná deskriptívnymi charakteristikami a koeficientom popularity položiek p. Vnútorná konzistencia bola hodnotená Cronbachovým koeficientom α, koeficientom ω, korelácie Pearsonovým koeficientom súčinovej korelácie. Výsledky. Sedemfaktorový a trojfaktorový model dotazníka ani jednofaktorové modely škál dotazníka nevykazujú dobrú zhodu s dátami. Modifikované jednofaktorové modely vykazujú dobrú zhodu s dátami. Vnútorná konzistencia škál je vo všetkých prípadoch nízka α = ω = ,55–,78. Položková analýza identifikovala problematické položky. Škály dotazníka navzájom korelujú. Výsledky otvárajú otázku, či ide o problém ovplyvnený viac prekladom, alebo súvisí s konštrukciou pôvodnej škály. V aktuálnej podobe v slovenských pomeroch dotazník PCI nedosahuje požadované psychometrické vlastnosti a sú potrebné jeho ďalšie modifikácie. Je potrebné vylepšiť zhodu viacfaktorových modelov s dátami a výrazne zlepšiť vnútornú konzistenciu dotazníka. Obmedzenia štúdie. Výberový súbor nie je reprezentatívny, vzhľadom na nepravdepodobnostný typ výberu a prevahu žien. Obmedzením je tiež exploračný charakter analýz modifikovaných modelov dotazníka PCI.

For about eight decades, research instruments in the social sciences have been orbiting around Likert’s proposal for his famous response scale. Before him, and also after he managed to impose it, many researchers have tried to find a better solution. This, however, has proven difficult. While solving methodological problems for measuring concepts, by concentrating all the responses in only five categories brings major disadvantages as well: it has extremely low variation, it does not produce metric scores unless combined with similar items, and it cannot be used as such for advanced statistical analysis. In this article, we propose using a continuous response scale as a solution to each of these problems. In our opinion, the possible application of this solution has an extremely high potential to advance social science research methodology.

This study reports on the validation of the Motivated Strategies for Learning Questionnaire (MSLQ), a self-report, Likert-scaled instrument, developed by Pintrich et al. (1991). The instrument consists of two sections, i.e., motivation in the process of self-regulated learning and the learning strategies of university students. The adaptation concerned only the first section, the learning strategies section was not part of the adaptation. The sample consisted of 284 students of the Faculty of Humanities at Tomas Bata University in Zlín (256 women and 28 men). The average age was 24, ranging from 19 to 49, with a standard deviation of 6.4 years. Within the adaptation of the MSLQ for the Czech educational environment, the exploratory and confirmatory factor analyses, Cattell’s scree test and parallel Monte Carlo analysis were performed. As a result, a 3-factor model was generated. The motivation scales tap into three broad areas: (1) expectancy (represented by academic self-efficacy; 4 items), (2) value (represented by task value; 6 items), and (3) affect (represented by test anxiety; 7 items). The internal consistency (Alphas) of the subscales varies from 0.76 to 0.84. Significant correlation between Academic self-efficacy and Task value subscales was.377. The results correspond to the theoretical model.

Background The Dizziness Handicap Inventory (DHI) was established to assess the impact of dizziness and balance problems on the quality of life. The aim of the study was to validate the Polish version of DHI for patients with vestibular disorders. Material and Methods Two hundred and thirty patients diagnosed with vestibular impairment and/or positional vertigo were included in the study. The mean age of the study group was 56.2 years (SD = 13.6). The factor structure (the principal component analysis − PCA), internal consistency (Cronbach’s α), and discrimination ability (the receiver operating characteristic [ROC] curve) were examined. Results A satisfactory internal consistency was found (Cronbach’s α coefficient = 0.92), while no floor or ceiling effect was revealed. The Dizziness Handicap Inventory demonstrated a good ability to discriminate between patients with and without the handicap (sensitivity and specificity about 80%, the cutoff point = 56). In PCA a 3-factor solution was obtained, with the factors related to restrictions in daily life, positional symptoms and visual-vestibular symptoms, which was not in agreement with the subscales provided in the original version. Conclusions The Polish version of DHI demonstrates satisfactory measurement properties and can be used to assess the impact of dizziness on handicap and the quality of life. The functional, emotional, and physical subscales were not confirmed. In particular, the functional subscale revealed no satisfactory internal consistency which provides an indication for further studies. Med Pr. 2019;70(5):529–34

The study aimed to construct and validate the Inclusive Competences Scale for educators (InComSedu). The basis for item generation was the “Profile of Inclusive Teachers”, a document developed by the european Agency for Special Needs and Inclusive education. Items were measured on a 5-point Likert scale. In order to test the validity and internal consistency of the scale, item analysis, exploratory and confirmatory factor analysis and Cronbach’s α were used. on a sample of Slovenian educators factor analyses proved the InComSedu had seven subscales: Team working and cooperation with others, Implementing knowledge about inclusive education and support, reflecting on and learning from inclusive practice, optimising challenges and approaching interdisciplinary, Accepting professional responsibility for each child’s development, Promoting resilience and professionality, and empowering children’s life skills. results indicate that InComSedu is a valid and reliable instrument for the evaluation of inclusive competences among educators.

In 2009, the SPARO questionnaire was one of the most used assessment methods in the Czech Republic (Urbánek, 2010), especially between psychologists in human resources, prisons, police, or the army. However, empirical evidence of its reliability and validity is missing. Using a significant sample of police officers and applicants to police, we researched the questionnaire's reliability and factor validity. About half of the scales do not have adequate internal consistency; the majority of them are not unidimensional. Factor validity is questionable, especially in the main components of the questionnaire, which are highly correlated. These correlations were also present in the original standardized samples as our and original correlation matrices do not differ. The factor structure of the two general factors items is not clear and two-dimensional. Our results do not support the use of the questionnaire in practice. It is necessary to confirm its’ predictive validity; the criterion validity is evaluated in our follow up study (Cígler & Rudá, 2021).

V roce 2009 patřil dotazník SPARO k nejpoužívanějším metodám psychologické diagnostiky v ČR (Urbánek, 2010), a to zejména mezi psychology působícími v personalistice, vězeňství, policii a armádě. Empirické důkazy jeho validity a reliability ovšem chybějí. S využitím rozsáhlého vzorku policistů a uchazečů o práci u policie jsme proto ověřili reliabilitu a faktorovou validitu dotazníku. Výsledky ukazují, že vnitřní konzistence je neuspokojivá u zhruba poloviny škál, jednotlivé škály navíc nejsou jednodimenzionální. Faktorová validita je problematická zejména u hlavních komponent dotazníku, které spolu oproti předpokladům silně korelují. Tyto korelace navíc byly přítomny i v původních standardizačních vzorcích, protože se neliší námi pozorované a originální korelační matice. Faktorová struktura dvou „obecnějších faktorů“ je komplikovaná, nelze v rozporu s teorií identifikovat dvě nezávislé latentní proměnné. Výsledky nepodporují využití dotazníku v běžné praxi. Za tímto účelem by bylo nezbytné prokázat prediktivní validitu jednotlivých škál dotazníku; souběžnou validitu ověřujeme v další studii (Cígler & Rudá, 2021).

Objectives. The aim of study was to test (a) the factorial structure of the BSI-18 instrument, (b) its basic psychometric attributes, (c) effect of gender, age, average monthly household income, and faith in God using representative sample of Czech respondents without declared somatic and psychiatric diagnosis. Subjects and setting. Responses were obtained from a representative sample of 1841 Czech persons (898 males, 943 females), average age 46,53; SD = 17,68, chosen using random quota sampling based on gender, age, and region. Results. Based on Czech representative general population the BSI-18 looks like internally consistent, unidimensional inventory. The factorial structure was not statistically influenced by gender, age, monthly income, and faith in God. The association of age and gender with Global Severity Index was not statistically significant. The effect of monthly income was nonlinear, respondents with highest and lowest income reported higher psychological distress in comparison with the respondents with average income. Likewise, the believers in God recorded a statistically significantly higher degree of distress compared to the unbelievers. Conclusion. The instrument can be used to reliably evaluate the psychological distress in the general population and the findings can also serve as a framework of reference for assessing the severity of distress in clinical trials. Study limitation. The findings are limited to a Czech general representative population sample.

Záměr. Cílem studie bylo testování (a) faktorové struktury BSI-18 nástroje, (b) základních psychometrických vlastností, (c) efektu pohlaví, věku, průměrného měsíčního příjmu a víry v Boha na podkladě odpovědí reprezentativního souboru českých respondentů bez deklarované somatické a psychiatrické diagnózy. Soubor a procedura. Soubor tvořilo 1841 osob (898 mužů, 943 žen), průměrný věk 46,53, SD = 17,68, vybraných náhodným kvótním výběrem na podkladě věku, pohlaví a regionu. Výsledky. Nálezy podpořily u reprezentativního českého obecného souboru existenci interně konzistentního jednodimenzionálního inventáře. Faktorová struktura nebyla statisticky významně ovlivněna pohlavím, věkem, mírou průměrného měsíčního přijmu ani vírou v Boha. Věk ani pohlaví nebyly statisticky významně asociované s indexem Celkové psychické zátěže. Efekt měsíčního příjmu domácnosti nebyl lineární, respondenti s nízkým a vysokým příjmem deklarovali vyšší míru psychické zátěže ve srovnání s osobami s průměrným příjmem. Rovněž jedinci věřící v Boha zažívali vyšší výskyt problémů ve srovnání s nevěřícími jedinci. Závěr. Inventář může být použit k spolehlivému vyhodnocení psychické zátěže u obecné populace. Rovněž ho lze využít jako referenční rámec pro posouzení závažnosti psychologické symptomatologie u klinických souborů. Omezení studie. Zjištění jsou omezena výhradně na český obecný reprezentativní vzorek populace.
