Reliability of DNS tests in cunical practise
Stýblová, Jaroslava ; Kobesová, Alena (advisor) ; Demeková, Júlia (referee)
Introduction: Functional testing which is used in rehabilitation is mainly based on aspection and palpation. It is a subjective examination of a patient and you cannot find out specific physical quantities with this method. If you want to use functional tests in clinical practise it is necessary to determine the reliability of the tests. Aim: To determine the inter-rater reliability for the DNS tests and to create a detailed descriptive statistics and a new evaluation sheet. Materials and methods: There were six experienced evaluators who are trained for the DNS method. We have worked with a mixed group of patients. There were patients with health problems as well as patients without any difficulties (n = 10 women, average age - 34, 5, n = 4 men, average age - 35, 2). We used percentage agreement, Fleiss's kappa coefficients (κ) and P-value. Results: The research of DNS tests reliability is innovative. Evaluators of DNS tests usually agree with each other. In some cases there is a problem with using Fleiss's kappa coefficients (κ) because of the position of relative frequencies. In most tests we found out that the inter-rater reliability is good (κ ≥ 0.80), substantial (0.60 ≤ κ < 0.80) and moderate (0.40 ≤ κ < 0.60). Conclusion: The evaluation of one character in a case of one patient by three...

Reliability Evaluation of Visual Perception Test
Balíková, Tereza ; Felcmanová, Lenka (advisor) ; Mlčková, Marie (referee)
This thesis called Verification of a Reliability of The Visual Perception Test built on a pilot study of Felcmanová (2015), who using test-retest reliability, developed a test for visual perception. Due to previous research including a smaller sample size, the main aim of this thesis was to gather data of a larger sample and compare the new and previous results. Given this objective, the test-retest methodology was therefore adopted for this project as well. Besides this main goal, recommendations were formulated for adjusting the test and manual (more detailed instructions, practical demonstration and evaluation examples). Simultaneously this research diagnosed the level of visual perception of children forming the research sample. The theoretical backgrounds builds the backdrop of current knowledge in the field of visual perception and diagnostic, to which results were eventually related. It further describes specifics of diagnostic of children in pre-school age. The chosen sample for the verification of reliability consisted of 57 pre-school age children. During the data exploration eight children were selected, whose results were found to present extreme values. As a consequence this research has found that the co-efficient of conformity of measurement through the test-retest method reached a...

Mutual comparison of fitness test results and floorball skills tests among Czech talented youth and youth from the Vysočina Region
Kovář, Jakub ; Dragounová, Zuzana (advisor) ; Tůma, Martin (referee)
Title: Mutual comparison of results of fitness tests and tests of floorball skills among talented Czech youth and youth from the Vysočina Region. Objectives: The main aim of the Master's thesis is to evaluate the level of player skills and fitness skills among regional youth teams and youth from the Vysočina Region. For the comparison, the categories of younger and older male and female pupils, and junior men and women were selected. Methods: For the purposes of this Master's thesis, the method of quantitative research of the categories of younger and older male and female pupils, and junior men and women in floorball from the Vysočina Region was applied. The floorball test battery of the Czech Floorball, consisting of fourteen player tests focused on floorball skills and fitness skills, of which seven scientifically standardized tests were selected, was used for testing. For the determination of validity, an expert analysis was used, a repeated measurement (test - retest) was performed to determine the reliability of the tests, and the Fleiss' Kappa value was calculated to determine the evaluators' concordance. Results: The results of the paper, based on the comparison of the data of the club from the Vysočina Region, and the regional teams' data, showed that girls (junior women and older female...

Health and Its Socioeconomic Indicators - Reliability and Validity Testing of Scales
Juráčková, Veronika ; Remr, Jiří (advisor) ; Hendl, Jan (referee)
The diploma thesis "Health and Socio-economic Indicators - reliability and validity testing of the PSAS" deals with a theoretical concept of health and its socio-economic indicators. A substantial part of the work concentrates on the application of PSAS tools to the Czech population and determining whether the range is reliable and valid for Czech respondents. To determine the reliability, a complex test is used for the whole range through the value of Cronbach's Alpha, and then the Item Response Theory (IRT) is also tested. The IRT test is done using the 18-point Likert's range of responses, of which is the PSAS composed. The validity is tested based on confirmatory factor analysis, using the construct validity as well as analysis of cognitive interviews for face validity. The secondary data analysis is done in SPSS, MPLUS, R, and IRTPRO programs. The last two programs are used to test the lesser known Item Response Theory.

Specific reliability of endurance shuttle swim test on 10m to 400m free style test at population of water polo players
Hauzner, Štěpán ; Musálek, Martin (advisor) ; Jurák, Daniel (referee)
Title: Specific reliability of endurance shuttle swim test to 10 m, to 400 m free style test at population of water polo players in relation age. Objectives: The aim is to approximate specific reliability of test for assessing endurance abilities at water polo players Methods: The work is a theoretical - empirical study, with the observation as the main research method. As the cross-sectional survey, testing was used as the basic method for data collection. A total of 15 participants were included in the study. The test set was created by the SK Usti nad Labem water polo players in the age category (18-22 years). The average age was 18.47 years (SD ± 1.20). Endurance Swimming Shuttle Test at 10 m made by Rechichi (2000) was used. We used test-retest method for the stability measure. Furthermore, the determination of the content equivalent of this test to the 400 m free swimming test was used to analyze the data obtained using descriptive statistical methods. Once the assumptions for parallelism of the tests were met, we used the correlation coefficient to approximate the specific reliability in the form of content equivalence and test stability. The Bland- Altman plot was used to assess of normality. Results: The reliability test (VCP) determined by the test-retest method Rel = 0.99. This result is...

Analytical methods for measurement error estimation in survey data
Chylíková, Johana ; Vinopal, Jiří (advisor) ; Kreidl, Martin (referee) ; Buriánek, Jiří (referee)
Analytical methods for measurement error estimation in survey data This dissertation aims at the domain of measurement error in social science survey data. To conceptualize and estimate measurement errors it employs the analytical and theoretical framework that stems from the analytical method of structural equation modeling (SEM) and Classical Test Theory (CTT), extended with the component of the systematic measurement error. This thesis has two goals that may contribute to development and extension of Czech social science methodology. The first goal is to illustrate methods of measurement error estimation, which has not been used for analysis of Czech data yet, and to point out to some problematical aspects of these methods. The second goal is to employ presented methods to obtain new findings regarding the quality of data from Czech surveys. The dissertation presents three empirical studies, each of which uses one of the methods defined within the presented theoretical and analytical framework. First study presents an analysis of reliability of measurement with the Quasi Simplex Model (QSM). It illustrates how to use the model and brings optimistic results regarding the reliability of the Czech EU SILC panel data. In the second study the confirmatory factor analysis model, operationally called...

Testing the Van der Veer et al. Fear-based Xenophobia Scale
Kunc, Michal ; Buchtík, Martin (advisor) ; Chylíková, Johana (referee)
The paper offers a brief theoretical reflection of the concept of xenophobia and a brief review of quantitative research on the topic. It uses reliability analysis, Confirmatory factor analysis and Mokken scale analysis to test the reliability and internal validity of the 9- tem van der Veer Et al. Fear-based xenophobia scale on a sample representative for the Czech Republic. It then uses the scale's results to forma n index which is then used to confirm several hypotheses to examine the construct's external validity. It reaches the conclusion that the scale is reliable and valid and suitable for use on the Czech population, however its results are too easily affected by the ordering of item options, and its results should therefore be used as an index to analyze other variables, not as a standalone source of information.
