The Logical Structure of Cronbach's Coefficient Alpha, and its Precision in Estimating Reliability under Measurement Models Assumptions. [PDF]

open access: yesJournal of Islamic Studies, 2009
The study examined three main research questions: 1- What is the logical structure of Cronbach's Coefficient Alpha and its implications" 2- Under what measurement models and cicumstances the use of Coefficient Alpha produce either accurate or biased ...

Don’t Forget the Model in Your Model-based Reliability Coefficients: A Reply to McNeish (2018)

open access: yesCollabra: Psychology, 2019
McNeish (2018) advocates that researchers abandon coefficient alpha in favor of alternative reliability measures, such as the 1-factor reliability (coefficient omega), a total reliability coefficient based on an exploratory bifactor solution (“Revelle’s ...

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

open access: yesFEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

Standard Errors for Reliability Coefficients

open access: yesPsychometrika
Abstract Reliability analysis is one of the most conducted analyses in applied psychometrics. It entails the assessment of reliability of both item scores and scale scores using coefficients that estimate the reliability (e.g., Cronbach’s alpha), measurement precision (e.g., estimated standard error of measurement), or the ...

Long‐Term Follow‐Up of Chemotherapy‐Associated Biological Aging in Women With Early Breast Cancer

open access: yesAging and Cancer, EarlyView.
Women threated with adjuvant chemotherapy for early breast cancer have sustained long‐term increase in p16INK4a,, a robust marker of cell senescence, suggesting a chemotherapy‐associated age acceleration. p16INK4a as well as other biomarkers may identify patients at greatest risk for senescence‐related diseases of aging.

TESTING HOMOGENEITY OF RELIABILITY COEFFICIENTS [PDF]

open access: yesETS Research Bulletin Series, 1962
ABSTRACTThe likelihood ratio significance test for the hypothesis of homogeneity of two empirical reliability coefficients is derived. It is assumed that both tests were administered to the same sample and are split into equivalent halves. A numerical example serves as an illustration.

Validity of a Wearable Digital Insole for Assessing Gait ON and OFF in Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Gait impairment is a distinctive symptom of Parkinson's disease that negatively impact mobility. We assessed the validity of wearable digital insoles against a validated reference gait analysis system for measuring select gait characteristics in patients with Parkinson's disease. Methods A comparative analysis between digital insoles

Location‐Specific Hematoma Volume Predicts Early Neurological Deterioration in Supratentorial ICH

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Early neurological deterioration (END) adversely affects outcomes in patients with intracerebral hemorrhage (ICH). This study aimed to determine the location‐specific hematoma volumes for END in supratentorial ICH patients. Methods We retrospectively analyzed supratentorial ICH patients presenting from two prospective cohorts.
