Internal Construct Validity of the Warwick-Edinburgh Mental Well-Being Scale (WEMWBS): A Rasch Analysis using Data from the Scottish Health Education Population Survey
TL;DR: A short 7 item version of WEMWBS was found to satisfy the strict unidimensionality expectations of the Rasch model, and be largely free of bias, and is preferable to the full 14 item version at present for monitoring mental well-being in populations.

TL;DR: This study provides Class II evidence that 20 mg tafamidis QD was associated with no difference in clinical progression in patients with TTR-FAP, as measured by the NIS-LL and the Norfolk QOL-DN score, supporting the hypothesis that preventing TTR dissociation can delay peripheral neurologic impairment.
Journal ArticleDOI
Internal construct validity of the Shirom-Melamed Burnout Questionnaire (SMBQ).
TL;DR: A revised 18 item version of the SMBQ satisfies modern measurement standards and offers the opportunity to identify potential clinical cases of burnout using its cut point.
Journal ArticleDOI
Critical Values for Yen’s Q3: Identification of Local Dependence in the Rasch Model Using Residual Correlations:
TL;DR: The results show that LD should be considered relative to the average observed residual correlation, rather than to a uniform value, as this results in more stable percentiles for the null distribution of an adjusted fit statistic.
Journal ArticleDOI
Using the Rasch model in nursing research: an introduction and illustrative example.
TL;DR: The Rasch model is useful for rigorous examination and development of measurement instruments in nursing research and facilitates disclosure of lack of invariance and other measurement problems that may not be easily detected by traditional analyses.

Coefficient alpha and the internal structure of tests.
TL;DR: In this paper, a general formula (α) of which a special case is the Kuder-Richardson coefficient of equivalence is shown to be the mean of all split-half coefficients resulting from different splittings of a test, therefore an estimate of the correlation between two random samples of items from a universe of items like those in the test.

TL;DR: A simulation of a clinical trial of the treatment of coronary artery disease by allocating 1073 patient records from past cases into two “treatment” groups at random failed to show any significant difference in survival between those patients allocated to the two treatments.

A Rasch Model for Partial Credit Scoring.
TL;DR: In this paper, an unidimensional latent trait model for responses scored in two or more ordered categories is developed, which can be viewed as an extension of Andrich's Rating Scale model to situations in which ordered response alternatives are free to vary in number and structure from item to item.
Journal ArticleDOI
A rating formulation for ordered response categories
TL;DR: In this paper, a rating response mechanism for ordered categories, which is related to the traditional threshold formulation but distinctively different from it, is formulated, in which subject and item parameters are derived in terms of thresholds on a latent continuum and discriminations at the thresholds.
