As outlined above, before we examined items for retention, the long-form structure (Hawley et al. 2011) of the previously published and present samples must first be evaluated for strong measurement invariance (i.e., equivalent loadings and intercepts).
We chose items for retention in the reduced item set that maximized item information I at this level of θ.
Using this framework and data from the qualitative and quantitative studies described above, the panel identified items for retention and rewording from Affectometer 2 and agreed the wording of new items.
Models were evaluated by their ability to produce subscales that (a) suggested three or more items for retention on a subscale, (b) had salient item factor loadings, (c) displayed internal consistency of items, and (d) exhibited theoretical and conceptual clarity of factors and items for measuring interprofessional collaboration.

We deemed the items appropriate for retention if they (a) possessed strong factor loadings (i.e., standardized factor loadings greater than 0.60), (b) were sufficiently distinct from other items (i.e., minimized redundancy), (c) qualitatively represented their intended construct, and (d) demonstrated normal distributive properties.
The standardized factor loadings for each of the 46 Stroke-PROM items were above 0.5, except for items PHD1, PHD2, and PHD3; however, these three items were recommended for retention by the results of CTT and IRT analyses.
For item sets which constitute a potential new scale, all the above Rasch assumptions are considered together to determine which items are most suitable for retention.
In such studies parietal involvement in distracter filtering seems to be unnecessary since irrelevant items had been eliminated before reaching parietal cortex which is responsible for retention of items in WM [4] [5].
Overall, a simple and parsimonious set of latent constructs was sought, with judgments based on the interpretability of the factor structure underlying the item variables, and three or more items were considered the minimum for retention for factors.
Under conventional factor analysis, the criterion for item retention was that the factor item loading should be at least.40.40
Given this inconsistency, the authors developed guidelines regarding the application of different decision rules to use for item retention.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
