Item analysis also revealed the overall psychometric adequacy of the items of the scale.
The results showed an improvement in the inter-rater agreement of five out of 12 items of the scale.
To the extent that the researcher removes items of the scale, the Cronbach's alpha tends to decrease.
First, items of the scale are not specific, and may equally well measure worry, self-worth and distress.
The scores of the 31 items of the scale were significantly affected by country and food concept, as well as through their interaction.
The 14 items of the SCALE focus on learning tasks, classroom practices, interactions between students and teachers, and the physical setting and availability of resources.
First, exploratory factor analysis was used to extract factors from 33 items of the scale in its application to 149 management major students.
The RM requires no assumptions about the latent variable being normally distributed as e.g. factor analysis models and furthermore tests the item fit of the individual items of the scale [33].
While the items of the scale "agency" talk about "me", the perspective of the scale "outcome" is different: the items are formulated as universal statements concerning the entire group of students.
Specific objectivity refers to that comparisons of persons level on the latent variable do not depend systematically on which items of the scale we use, and that comparisons of items do not depend on which persons in the sample we use, within the specific frame of reference.
The items of the scale were completed by self-report.
