This study differs from both these approaches, as it does not rely on the experts' opinions to assure face and content validity, but applies the ICF directly as an instrument of geriatric assessment to select more adequate items, while aiming to develop new scales using ICF taxonomy.
In view of these results and acknowledging an adequate item-factor specification as conveyed by the interim E/CFA, a bifactor model was fitted to examine the existence of a general factor, yet still accounting for (conditional on) the three specific factors (Table 1, Model D).
For the US version, multitrait analyses were performed which also showed adequate item-internal and item-discriminant validity for the majority of items [ 17].

Based on the standardized residuals from Model 1 and the item-total correlations, we removed the item of availability of adequate space for residents, leaving 33 items in Model 2. Model 3 contained the three remaining ACT concepts (informal interactions, formal interactions, and structural and electronic resources).
The presence of adequate targeting of the items to the sample, the sample size required to perform a Rasch analysis should have included at least 200 observations in order to yield stable person and item estimates (±0.5 logit at 95% confidence level) and based on an expected standard error level of ±0.1 [ 71].
The item 'availability of adequate emergency drugs in stock' was scored highest in this group and second overall.
This article complements the more detailed SCRIBE 2016 Explanation and Elaboration article (Tate et al., 2016) that provides a rationale for each of the items and examples of adequate reporting from the literature.
