Abstract:

This study aims to describe the effects of variability through data simulation to determine which aspect of variability that maximizes coefficient of Cronbach Alpha reliability. Cronbach Alpha is widely used for estimation of reliability, in recent still. This study served a conceptual and practical simulation for estimating the profound aspect of Cronbach Alpha coefficient relating to the variability of the data.

Abstract:

The current article shows the importance of involving an adequate size of try-out samples based on two considerations: the power of the analysis and the accuracy of parameter estimates. Two simulation studies were conducted to achieve two purposes. The first was to show the disadvantages of calculating reliability estimates with inadequate sample sizes due to lower power or high inaccuracy. The second objective was to show the performance of two formulas for calculating the required sample size: Feldt and Bonett. Based on their performance, the recommendation on which formula should be used wa

Abstract:

Reliability as one the psychometric properties of a research and measurement instrument is very desirable in research, under the classical test theory(CTT). One group of such reliability measures is that of internal consistency of a scale. Cronbach Alpha and KuderRichardson formula 20 are measures of internal consistencies. In many texts, authorities specify that Kuder-Richardson formula 20 should be applied when test items are dichotomously scored while Cronbach Alpha should be applied when test items are not scored dichotomously. These guide lines are religiously adhered to by both researche

ABSTRACT Objective: To determine the validity and reliability of the Filipino Dizziness Handicap Inventory (FDHI) questionnaire among geriatric patients with dizziness. Methods:Design: Linguistic ValidationSetting: Tertiary Government Training HospitalParticipants: Twenty-five (25) patients Results: The dizziness handicap inventory was translated into Filipino by a Filipino language specialist and an ENT specialist who are experts in their field. The translated version was easily understood by the 25 geriatric patients with Cronbach α scores of .957 overall [M = 2.16; SD = 1.

Abstract:

Objective: Internal consistency of scales is crucial for the quality of clinical practices, and scales that measure various aspects of clinical disorders must possess acceptable internal consistency. In the assessment of the internal consistency of the scales, the present study considered the Cronbachs alphas coefficient. This study aims (1) to provide a practical sample size guide based on Cronbachs alpha for medical researchers; (2) to investigate the factors related to the determination of the sample size needed for a correct estimation of Cronbachs alpha. Method: The calculation steps

Abstract:

De nombreux chercheurs en psychométrie soutiennent que le coefficient alpha de Cronbach (1951) n’est pas une mesure adéquate de la fidélité (reliability) d’un test. C’est dans l’optique d’améliorer les pratiques d’analyse de données que ce court article va présenter les fondements théoriques de la fidélité, synthétiser les principales limites de l’alpha en plus de présenter de façon concise deux alternatives très prometteuses: le great lower bound et l’omega. Des logiciels gratuits et en téléchargement libre sont mentionnés pour obtenir un estimé de ces coefficients.

Abstract:

Introduction. The use of traditional medicine among the adult population is prevalent. Previous studies have explored the use of traditional medicine among adults. However, traditional medicine usage among adolescents is still rare, especially among elementary school students. Therefore the instruments for research on the use of traditional medicine among adolescents are also still limited. Objective. This study aims to calculate the reliability scale of a questionnaire based on the Theory of Planned Behavior. The questionnaire can be used to explore the behavior of using traditional medicine

Abstract Academic achievement is an important indicator of academic success. This study aims to analyze the effect of self-regulated learning in mediating the effect of parental involvement on academic achievement. Data collection for participants in this study (n = 206) was carried out using the convenience sampling technique. The validity of the items in the instrument was tested with the content validity index (CVI) and the reliability test used an internal consistency approach. The results of testing the validity of the parental involvement scale showed that the V Aiken coefficient ranged

Abstract:

The stroop task is a method of measuring selective attention that demonstrates automatic and controlled cognitive processes. The stroop task as a digitalized measuring tool makes it easier for users to administer and score efficiently. However, this digital stroop task is not yet available in the Indonesian version. Meanwhile, the use of English has not been fully mastered by layers of Indonesian society, which causes the risk of less than optimal test results. This research is a non-experimental quantitative research which aims to test the psychometric properties using a test-retest approach
