Edinburgh Feeding Evaluation In Dementia Scale
The Edinburgh Feeding Evaluation in Dementia (EdFED) Scale is a psychometric screening tool to assess difficulty with self-feeding in older people with dementia. It was developed at The University of Edinburgh by Roger Watson and Ian Deary. The original EdFED was composed of 11 items and was validated using Guttman scaling but a subsequent version was validated using Mokken scaling and was composed of only ten items. The scale measures aspects of the level of intervention required by carers (for example, verbal prompting), observations related to feeding (for example, spillage) and behavioural aspects (for example, refusal to eat). The items are scored on a three-point Likert type scale from ‘0’ (never) to ‘3’ (often) observed items on the scale. In 2014 Alzheimers Disease International highlighted the utility of the EdFED in their ‘’’Nutrition and Dementia’’’ report. The EdFED has been translated and validated in several languages including Chinese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychometrics
Psychometrics is a field of study within psychology concerned with the theory and technique of measurement. Psychometrics generally covers specialized fields within psychology and education devoted to testing, measurement, assessment, and related activities. Psychometrics is concerned with the objective measurement of latent constructs that cannot be directly observed. Examples of latent constructs include intelligence, introversion, mental disorders, and educational achievement. The levels of individuals on nonobservable latent variables are inferred through mathematical modeling based on what is observed from individuals' responses to items on tests and scales. Practitioners are described as psychometricians, although not all who engage in psychometric research go by this title. Psychometricians usually possess specific qualifications, such as degrees or certifications, and most are psychologists with advanced graduate training in psychometrics and measurement theory. In ...
