They were invited to score the indicators on a scale of 1 9 for their appropriateness (1: not appropriate; 9: very appropriate), in the context of the care that would be expected to have been delivered in Australia from 2009 to 2010.
Modern test theory with Rasch analysis provides additional and more detailed psychometric information regarding the dimensionality of the scale, validity and appropriateness of summated scores, response categories, targeting of the scale, and item bias, i.e. differential item functioning (DIF).
The research team also evaluated the value of each sub-scale and appropriateness of each item in the scale for 3- to 6-year-olds in Hong Kong.
This analysis will also be stratified according to the degree of appropriateness and FRAX scales.
Numerical scores are assigned to the questions to represent the degree of appropriateness using four-points scale where 1 represents highly inappropriate and 4 represents highly appropriate.
It was necessary to use a 9-point scale in order to facilitate our analysis of appropriateness and disagreement using established Research ANd Development (RAND/UCLA) methodology (see appendix) [ 19- 21].
Twelve experts reviewed the tool for content validity and gave feedback about each item regarding its precision, feasibility and appropriateness on a scale of 1 to 4 (1= very inappropriate, 2= inappropriate, 3= appropriate, and 4= very appropriate).
The interviews were structured to evaluate the caregiver question/answer process, assess comprehension and refine question wording, optimize the response scales, confirm appropriateness of the recall period, confirm the content validity of the items, and confirm there were no missing concepts.
The objectives of the cognitive debriefing interviews were to understand the question-and-answer process used by the caregiver, refine question wording, optimize the response scales, confirm appropriateness of the recall period, and confirm the content validity of the instrument.
This refers to how well each item fits within the proposed scale and the appropriateness of the scaling assumptions.
30– 33 The Medication Appropriateness Index uses ten items to assess the degree of appropriateness of a particular medication along with a three-point Likert rating scale.
