Cíl: Cílem studie bylo zjistit test-retest reliabilitu testu Odorized Markers Test (OMT). Tento psychofyzikální test založený na identifikaci pachových látek je využíván v české populaci pro screening anosmie. Vyšetření se skládá ze dvou částí. V první části jsou vyšetřovaní požádáni, aby spontánně pojmenovali pachové látky. Ve druhé části vyšetřovaní vybírají nejvhodnější název pachové látky ze čtyř nabízených možností. Metody: Do studie bylo zařazeno 150 osob: 77 zdravých a 73 pacientů s poruchou čichu. Čich byl vyšetřen testem OMT. Retest byl proveden v průměru 2 dny po prvním testování. Výsledky: Koeficient korelace mezi prvním testováním a retestováním byl 0,91. Test-retest ukázal, že zdravé osoby dosáhly vyšších bodových zisků než pacienti s poruchou čichu (p < 0,001). První část testu vykazovala vyšší stupeň vnitřní konzistence než druhá část. Výsledky byly při prvním testování α = 0,9 a 0,56, resp. a při opakovaném testování α = 0,89 a 0,65, resp Anosmie byla zjištěna u 26 (17 %) pacientů při prvním testování a 27 (18 %) při retestování. Závěr: Mezi prvním testem a retestem byla nalezena pozitivní signifikantní korelace. Vnitřní konzistence byla uspokojivá jak v prvním testu, tak v retestu. Na základě výsledků naší studie je OMT spolehlivým a validním testem pro vyšetření čichu v klinické praxi.
Aim: The aim of this study was to determine the test-retest reliability of the Odorized Markers Test (OMT). This psychophysical test is a tool for screening anosmia based on the identification of odorants. The test is used for the Czech population. Examination technique consists of two parts. First, subjects are asked to spontaneously name the odorants and second, subjects have to choose the most proper name for an odorant from four descriptors. Methods: The participants included 150 subjects: 77 healthy subjects and 73 patients with smell disorders. Olfactory functions were assessed using the OMT. Retest was performed on an average interval of 2 days. Results: The coefficient of correlation between the first test and retest was 0.91. The test-retest showed that the controls reached higher scores than patients with olfactory impairment (P < 0.001). The first part of the test showed higher degree of internal consistency than the second part. The results for the first testing were α = 0.9 and 0.56, respectively, and for retesting α = 0.89 and 0.65, respectively. Anosmia was found in 26 (17%) and 27 (18%) patients on test and retest, respectively. Conclusion: Positive significant correlation was found between the first test and retest. Internal consistency was satisfactory in both the first test and retest. Based on the results of our study, OMT is a reliable and valid test for olfactory evaluation in clinical practice.
Východisko: Test sémantické slovní produkce (kategorie zvířata) je jedním z neuropsychologických testů. Cílem naší studie bylo Zjistit efekt nácviku a spolehlivost opětovného měření minutové slovní produkce jakož i 30sekundové slovní produkce a verze jmenování 12 zvířat u populace seniorů. Metodika: Vyšetřili jsme 23 dobrovolníků (průměrný věk 66,1 ± 7,7; průměrná délka vzdělání 13,4 ± 2,5 let; MMSE > 28) testem sémantické slovní produkce s opakováním po 6 týdnech a 6 měsících. Výsledky: Pokusné osoby vyjmenovaly během jedné minuty (27,1 ± 5,9; 28,1 ± 5,4; 28,0 ± 6,4) zvířat, za 30 sekund (17,7 ± 4,0; 18,4 ± 3,0; 18,6 ± 4,2) a 12 zvířat vyjmenovali za (19,6 ± 9,2; 16,9 ± 4,5; 16,7 ± 6,9) sekund. Efekt nácviku byl detekován pouze při jmenování 12 zvířat při srovnání 1. a 3. testování Wilcoxonovým párovým testem (exact p < 0,001, 95% IS -1 až -5) a znaménkovým testem (p < 0,001). Korelace mezi 1. a 2. resp. 2. a 3. a 1. a 3. vyšetřením byly pro jednominutový test (Pearsonovo r = 0,750, r = 0,525, r = 0,366), pro 30sekundový test (Pearsonovo r = 0,709, r = 0,666, r = 0,562) a pro test 12 zvířat (Spearmanovo rs = 0,469, rs = 0,477, rs = 0,567). Diskuze: Test 12 zvířat se ukázal jako nejvíce citlivý k efektu nácviku. Suboptimální test-retest reliabilitu si vysvětlujeme spíše zvoleným souborem než charakterem testů.
Background: Categorical verbal fluency test (CVFT) is one of many neuropsychological tests. The aim of the study was to evaluate practice effect and test-retest reliability of one minute, 30 seconds and the short version of CVFT (wherein the subjects were asked to recite 12 animals as fast as they were able) in seniors. Methods: We assessed 23 healthy volunteers with mean age 66.1 ± 7.7 years, mean education 13,4 ± 2,5 years, MMSE ? 28 with CVFT and shorter variants and we retested them after 6 weeks and 6 months. Results: Volunteers recited (27.1 ± 5.9; 28.1 ± 5.4; 28.0 ± 6.4) animals during 1 minute and (17.7 ± 4.0; 18.4 ± 3.0; 18.6 ± 4.2) animals during 30 seconds. The mean time to recite 12 animals was (19.6 ± 9.2; 16.9 ± 4.5; 16.7 ± 6.9). The practice effect was detected only in recitation of 12 animals between 1st and 3rd assessment by Wilcoxon signed rank test (p < 0.001; 95% CI -1 to -5) and Sign test (exact p < 0.001). The correlations between 1st and 2nd, 2nd and 3rd respectively 1st and 3rd assessment were for one minute test (Pearson’s r = 0.750, r = 0.525, r = 0.366), for 30 seconds test (Pearson’s r = 0.709, r = 0.666, r = 0.562) and for 12 animals test (Spearman’s rho = 0.469, rho = 0.477, rho = 0.567). Discussion: Twelve animals recitation test was the most sensitive to practice effect. We explain suboptimal test-retest reliability more due to chosen sample than tests properties.

Testové-retestové korelační indexy celkového skóre SPZR za celou rodinu byly po 3 dnech 0,982 a 0,980 po 3 týdnech. Závěr: Testování dotazníku SPZR prokázalo jeho velmi dobrou míru stability v čase.
Objective: To verify the reliability of the Czech version of the Family Eating and Activity Habits Questionnaire (SPZR).Methods: A three-day and a three-week interval of test and re-rests were used to verify the stability of the SPZR questionnaire over time. The research sample consisted of 47 families with children aged 6–12 years.Results: For individual family members (mother, father and child), the test-retest correlation coefficients for each scale and total score of the questionnaire ranged from 0.887 to 0.984 after 3 days and 0.781 to 0.980 after 3 weeks. The test-retest correlation coefficients of the total SPZR score for the whole family were after 3 days 0.982 and 0.980 after 3 weeks.Conclusion: The questionnaire has a very good reliability.
OBJECTIVES: The purpose of this study was to assess the test-retest reliability of selected items based on self-reports, measuring problem behaviour in the Slovak and Czech version of the HBSC survey questionnaire. METHODS: The data from test-retest study, based on an international Health Behaviour in School-aged Children (HBSC) study and consistent with its methodology, were analysed. A sample of 580 primary school pupils (51.2% of boys), grades five and nine participated in a test and retest with a four-week interval. Six items concerning problem behaviour were evaluated overall and stratified by gender and age. RESULTS: Analyses of test-retest reliability indicated modest (0.30 to 0.49), moderate (0.50 to 0.69), or high (0.70 to 1.00) reliability across nearly all questions, with some reliability differences in analyses by gender and age. In general, findings of present study suggest the moderate reliability of measures of smoking, drunkenness, fighting and negative relationship to school, modest reliability of measures of bullying behaviour, and low reliability of measure of truancy. CONCLUSIONS: The overall findings of this study suggest that most of selected indicators in the HBSC survey questionnaire have satisfactory test-retest reliability. Further test-retest studies in a large and diverse sample, as well as validity studies, should be considered for the future HBSC study.

Aim: The aim of this quantitative study is to introduce the Czech version of the PIH scale and the specific aspects of validity and reliability. The partial objectives are the factor structure of the scale, its reliability and validity, and subsequent verification of the possible application of the scale on the Czech population and the evaluation of other results obtained using the exploratory factor analysis. Methods: The study describes language validation PIH scale and psychometrically characterizes the PIH scale on the group of 230 patients with chronic cardiovascular disease. The results are calculated using descriptive statistics, reliability analysis, factor analysis and programs Excel and IBM SPSS. Results: The exploratory factor analysis shows four-factor solution. The value of Cronbach’s alpha 0.91 shows a high reliability of the PIH scale. The split-half reliability 0.83 and test-retest reliability 0.81 shows its good reliability. Conclusion: The results of the study provide information on the factor solution and the PIH scale reliability which confirm its good psychometric characteristics. It has been confirmed that the PIH scale is suitable for use in the clinical conditions of the Czech Republic healthcare. The research is supported by the project IGA_FZV_2017_003 Psychometric validation of PIH scale in patients with chronic cardiovascular disease.

Dotazník hodnocení intenzity chuti po jídle umožňuje posouzení alimentárního chování jedince. Extrémní stravovací vzorce jsou typické pro osoby s poruchami příjmu potravy, z toho důvodu může být dostupnost vhodného nástroje pro měření intenzity bažení po jídle významným faktorem pro diagnostiku i stanovení vhodného postupu léčby poruch výživy. Cílem naší studie bylo ověřit reliabilitu české verze dotazníku General-Food Craving Questionnaire-Trait (G-FCQ-T), který byl do češtiny přeložen M. Světlákem a M. Černíkem. Pro ověření stability dotazníku v čase byl použit třítýdenní časový odstup testu a retestu, stejný jako aplikovali autoři originálního dotazníku. Výzkumný soubor byl tvořen 391 vysokoškolskými studenty (157 mužů a 234 žen) ve věku 18–21 let. Analýza dat prokázala velmi dobrou vnitřní konzistenci dotazníku, Cronbachův koeficient alfa pro hrubé skóre činil 0,93, a dobrou míru stability v čase, test-retestová reliabilita po 3 týdnech byla 0,82. Česká verze dotazníku G-FCQ-T má tedy velice dobrou stabilitu v čase i vnitřní konzistenci. Dotazník je vhodný pro použití v českém prostředí ve výzkumu i v klinické praxi.
A questionnaire evaluating the intensity of food craving allows assessing the alimentary behaviour. Extreme eating patterns are typical of people with eating disorders; therefore the availability of suitable tools for measuring the intensity of food cravings could be an important factor for the diagnosis and determining of the appropriate treatment procedure for eating disorders. The aim of the study was to verify the specific and generic reliability of the Czech version of General-Food Craving Questionnaire-Trait (G-FCQ-T) which was translated into Czech by M. Světlák and M. Černík. A three-week interval of test and retest reliability was chosen, the same time as the authors of original questionnaire applied. The research sample consisted of 391 university students (157 men and 234 women) aged 18–21 years. The data analysis showed a very good internal consistency of the questionnaire, Cronbach’s alpha was 0.93 for total score; and a good stability over time, the test-retest reliability was 0.82 after 3 weeks. Therefore, the Czech version of the questionnaire G-FCQ-T has a very good specific and generic reliability. The questionnaire is useful both for the research and the clinical practice in the Czech environment.

OBJECTIVES: Participation in organized activities is related with a range of positive outcomes, but the way such participation is measured has not been scrutinized. Test-retest reliability as an important indicator of a scale's reliability has been assessed rarely and for "The scale of participation in organized activities" lacks completely. This test-retest study is based on the Health Behaviour in School-aged Children study and is consistent with its methodology. METHODS: We obtained data from 353 Czech (51.9 % boys) and 227 Slovak (52.9 % boys) primary school pupils, grades five and nine, who participated in this study in 2013. We used Cohen's kappa statistic and single measures of the intraclass correlation coefficient to estimate the test-retest reliability of all selected items in the sample, stratified by gender, age and country. RESULTS: We mostly observed a large correlation between the test and retest in all of the examined variables (κ ranged from 0.46 to 0.68). Test-retest reliability of the sum score of individual items showed substantial agreement (ICC = 0.64). CONCLUSIONS: The scale of participation in organized activities has an acceptable level of agreement, indicating good reliability.

Chair rise performance is incorporated in clinical assessments to indicate fall risk status in older persons. This study investigated the test-retest reliability of a pendant-sensor-based assessment of chair rise performance. Forty-one older persons (28 females, 13 males, age: 72-94) were assessed in two sessions with 3 to 8 days in between. Repeated chair rise transfers were measured after different instructions. Relative and absolute test-retest reliability of chair rise measurements in individual tests and average over all tests were evaluated by means of intra-class correlation coefficients (ICCs) and standard error of measurement (SEM) as a percentage of the measurement mean. Systematic bias between the measurements in test and retest was examined with paired t-tests. Heteroscedasticity of the measurements was visually checked with Bland-Altman plots. In the different test conditions, the ICCs ranged between 0.63 and 0.93, and the SEM% ranged between 5.7% and 21.2%. The relative and absolute reliability of the average over all tests were ICC = 0.86 and SEM% = 9.5% for transfer duration, ICC = 0.93 and SEM% = 9.2% for maximum vertical acceleration, and ICC = 0.89 and SEM% = 10.0% for peak power. The results over all tests indicated that a fall risk assessment application based on pendant-worn-sensor measured chair rise performance in daily life might be feasible.
