The functional neuroanatomy of language localization in dyslexia has primarily been studied in the context of reading. However, dyslexia is sometimes referred to as a “language-based learning disability,” yet the functional signature of the core language comprehension network in dyslexia is far less understood. This thesis presents a series of studies designed to compare the functionality of the brain regions supporting linguistic processing between typical and impaired readers in order to characterize the cortical language network in dyslexia. First, we investigate the extent to which the efficiency (or quality of data vs. amount of scan time) of a functional language localizer based on passive spoken language comprehension can be maximized in Chapter 2. By demarcating the language network based on smaller amounts of data and testing stability and reliability within this framework, we found that scan time can be substantially reduced without sacrificing functional specialization for language. In Chapter 3, we apply the spoken language localizer to determine differences in functional organization of language in dyslexia and provide evidence that the core spoken language comprehension network is not markedly different between typical readers and those with dyslexia. We compared the individual activations from whole-brain analysis and functional profiles in the canonical language-selective regions and found that the functional response of localized language regions in individuals with dyslexia was as selective as in typically reading adults. Chapter 4 follows up on the functional evidence reported in Chapter 3 to examine the structural connectivity within the same functional language network and additionally found essentially no differences between controls and dyslexia, further supporting the observations made in Chapter 3 that core linguistic processing is intact in dyslexia. All together, these findings converge on the suggestion that individuals with dyslexia do not rely on a separate cognitive architecture for language, potentially revealing important new insight into the dissociation of language specialization abilities and reading difficulty in dyslexia.

Bakgrund: Nacksmärta är ett vanligt förekommande besvär och en av de främsta orsakerna till att söka vård hos fysioterapeut. Nackbesvär kan leda till förändringar i proprioception, både medveten och omedveten, vilket kan leda till en nedsatt balans. Undersökning av omedveten proprioception har gjorts genom att mäta posturalt svaj vid stimulering av muskelspolar via lokala muskelvibratorer i tidigare studier. Ingen studie har dock undersökt reliabiliteten vid stimulering av nack- och vadmuskler hos personer med respektive utan nacksmärta   Syfte: Studiens syfte var att utvärdera inter-day reliabilitet för posturalt svaj hos personer med eller utan nacksmärta genom att mäta CoP på WBB där deltagarna ges vibrationer på vader, nacke respektive underarmar.   Metod: 50 deltagare deltog i studien, 25 deltagare med nacksmärta och 25 friska kontroller. Deltagarnas CoP mättes på en WBB där deltagarnas förändring av CoP mättes innan, under och efter att vibrationer getts på vader, underarmar respektive nacken. Deltagarna testades vid två tillfällen med 7 dagars mellanrum. ICC2,1 användes för att beräknade relativ reliabilitet. Ett ICC-värde ≥ 0,75 bedöms som god reliabilitet. Absolut reliabilitet beräknades med SEM. Beroende t-test utfördes för att undersöka eventuell systematisk bias såsom adaptioner eller inlärningseffekter mellan testtillfälle 1och 2.   Resultat: Studiens resultat uppvisade en måttlig till utmärkt relativ reliabilitet (ICC = 0,69 - 0,89) för A/P amplituden för hela gruppen och SEM-värden var mellan 0,51 - 1,17 vilket utgör ca 20 - 30% av medelvärdet för de flesta svajvariablerna. En signifikant inlärningseffekt kunde ses för både A/P och M/L amplituden vid vibration av vadmuskulaturen (p = 0,015 - 0,017).   Slutsats: Studiens resultat visar på en acceptabel reliabilitet och testmetoden kan användas i såväl forskning som klinisk användning vid undersökning av posturalt svaj med eller utan vibration. / Background: Neck pain is a common occurrence and one of the main reasons for seeking care at a physiotherapist. Neck disorders can lead to changes in proprioception, both conscious and unconscious, which can lead to a reduced balance. Investigation of unconscious proprioception has been done by measuring postural sway in the stimulation of muscle spindles via local muscle vibrators in previous studies. However, no study has investigated the reliability of stimulation of neck and calf muscles in people with or without neck pain   Purpose: The purpose of the study was to evaluate inter-day reliability on postural sway in people with or without neck pain by measuring CoP on WBB where participants receive vibration on the calf, neck and forearms.   Method: 50 participants participated in the study, 25 participants with neck pain and 25 healthy controls. Participants change of CoP was measured before, during and after vibration was given to calf, forearm and neck. Participants were tested on two occasions at 7-day intervals. ICC2,1 was used to calculate relative reliability. An ICC value ≥ 0.75 is considered to be good reliability. Absolute reliability was calculated with SEM. Dependent t-test was performed to investigate any systematic bias such as adaptations or learning effects between test 1 and 2.   Results: The results of the study showed a moderate to excellent relative reliability (ICC = 0.69 - 0.89) for the A/P amplitude and SEM values ​​were between 0.51 - 1.17 which represents about 20-30% of the mean for most sway variables. A significant learning effect could be seen for both the A/P and M/L amplitude in vibration of the calf muscles (p = 0.015-0.017).   Conclusion: The results of the study demonstrate acceptable reliability and the test method can be used in research and clinical to investigate postural sway with or without vibration.

Background: The maximum rate of oxygen consumption (V̇O2max) can be measured through numerous tests, either directly or indirectly, where direct methods are considered more accurate, whereas indirect methods are more of an estimation with various degrees of reliability. Cooper's Test is one example of an indirect method considered reliable in estimating V̇O2max, with reliability coefficients ranging between 0.897-0.960. Cooper's Test is thus a test that is often used when estimating V̇O2max. However, there is a lack of test-retest research done utilising Cooper's Test on a younger population, which is the reasoning behind this study focusing on adolescents. Aim: The aim of the study was to study the test-retest reliability of Cooper's Test, in adolescents aged 16-19 years. Methods: Twelve healthy adolescents, aged 16-19 years, attending a sports high school participated in a test-retest study (test 1 and test 2) of Cooper's Test. The tests were performed on the short sides of a synthetic grass field, with 66 metres between the two sides, were the participants were instructed to cover as much distance as possible, with high motivation and intensity, for the whole 12 minutes of the Cooper's Test. Each individual participant's data was measured, recorded and later analysed. The total distance covered was then translated into miles and compared to Cooper's original estimated maximal oxygen consumption table for an estimation of each participant's V̇O2max value in ml*kg-1*min-1 from test 1 and test 2. The data from the test-retest and its variance was then analysed by a two-way mixed model of intraclass correlation coefficient (ICC) with an absolute agreement type. Results: The analysed data from test 1 and test 2 of Cooper's Test showed the results of an ICC (95% CI) of 0.06 (-0.353 to 0.544), indicating a substantial error variance between the two separate Cooper's Tests. Conclusion: The data and analysis from this study implied that Cooper's Test was not reliable in the study population, consisting of adolescents. Possible factors influencing the result however were lack of participant motivation and the level of intensity variance during the test-retest of Cooper's Test. Further researchers and amateur and professional users should keep these factors in mind when utilising Cooper's Test to predict V̇O2max. More research is needed within this study's age population to draw any definite conclusions on the reliability of Cooper's test on adolescents.

Many performance-based assessment tools are available to measure upper extremity function. Most define hand function by the time taken to complete a task. A new computer game-based hand-arm function evaluation (GHA) tool has been developed to quantify fine and gross object manipulations skills. Objective of this study was to evaluate the test-retest reliability and convergent validity of the GHA assessment tool. Thirty stroke clients with the mean age of 68.41 years were recruited. Test-retest reliability was assessed by Intraclass correlation coefficient (ICCs) and t-test. Convergent validity between GHA and the Wolf Motor Function Test (WMFT) was determined using the Pearson’s correlation coefficient. Most of the GHA outcome measures had moderate to high ICC (0.5-0.9). With scant exceptions, low correlations were observed between GHA measures and WMFT score. The ICC values reflected the complexity of the tasks, more complex task showed lower ICCs values. / October 2016

The purpose of this study was to determine the test-retest reliability of the Revised Conners' Parent Rating Scale. The Conners' Parent Rating Scale (CPRS-48) was administered to 59 elementary school children between the ages of 5 and 10 years. After a period of two weeks, the same children were re-tested with the CPRS-48. The results of this research lend support to the integrity of the test-retest reliability of the CPRS-48. The need for further psychometric studies on the Conners' Scales is noted.

This thesis deals with personal integrity and its testing for the job tender. The main objective is to determine the test-retest reliability of the integrity test, which is currently being developed and studied at the National Institute of Mental Health in Klecany. Another aim of the work is to compare the Czech version of the integrity test, a whole set of psychological tests designed to investigate the integrity intended for recruiting new employees, and the findings of foreign tests, which are used primarily in the United States. The use of integrity tests is a common practice abroad in the selection process of new employees, for example in lower administration or positions working with money. Work has both theoretical and practical character. The theoretical part summarizes the findings about integrity from authors throughout history, present information about foreign integrity test (types, weaknesses, ethical issues of testing, the proposed rules for the implementation of integrity tests for job tenders for organization, etc.). Finally, it discusses psychometrics and required characteristics for quality tests. The practical part is based on a test-retest study that was conducted on a sample of 51 respondents in the time interval of 4 to 5 months. Respondents were repeatedly presented with a...

This methods-oriented dissertation focuses on the psychometric evaluation of the Feeding Your Preschooler Questionnaire (FYPQ) designed to assess the eating habits and diet quality of young children. Parental proxy reports (n=135) were obtained through pen and pencil administration of the FYPQ and an in-person interview using a 24- hour food recall (24HR).Test-retest reliability (n=82) was determined using a repeated measures design with Wilcoxon signed rank tests and Spearman correlations for the food frequency questionnaire (FFQ) portion of the survey, parental self-efficacy, parental role modeling, parental practices, and parental perception of child food preference regarding fruits and vegetables scales. Test-retest reliabilities ranged from r=.53 for water to r=.84 for vegetables for the FFQ and from r=.64 for role modeling to r=.71 for parental perception of child preference for the psychosocial measures. Concurrent construct validity (n=107) was examined with a cross-sectional study design using the Wilcoxon signed rank test, Spearman correlations, and cross-classification analysis into quartiles of food group intakes. Spearman’s correlations between the FFQ and the 24HR were .46 for milk, .22 for fruit, .22 for vegetables, .11 for grains and .07 for protein. Cross-classification analysis revealed that 29% of children were classified in the same quartile and 69% in the same or within one quartile, and gross misclassification ranged from 2% to 10%. Nomological validity was examined using weighted least squares regression. Two regression analyses with fruit and vegetable intake on first the FFQ and second the 24HR as the dependent variable examined the influences of psychosocial environmental predictors and food insecurity. The FFQ regression model explained 28% (p<.05) of the variance in fruit and vegetable intake, with the significant predictors of parental role modeling and food insecurity. The 24HR regression analysis predicting fruit and vegetable intake explained 11% (p<.05), with parental perception of child preference and parental role modeling as significant predictors. In summary, the FYPQ demonstrated good test-retest reliability. The study provides evidence of concurrent validity for the FFQ for assessment of milk consumption and fruit and vegetable variety in preschool children's diets and of nomological validity in the prediction of fruit and vegetable consumption. / text
