The final items defining the scales of individuals' awareness of mould infection are presented in Table 4.
Cronbach's alpha coefficient was used to measure the internal consistency of the items defining the dependent variable, knowledge of HIV/AIDS; it was 0.75.
To overcome the latter problem without significant compromise of the first issue, we created the following four composite scores from items defining the same concept by adding responses of identified variables giving equal weights to each item.
As "remembered" items defined the SM measures (see fMRI scanning and data analysis), age group and drug effects on the proportions of items judgments recollected versus familiar, and on RTs for these response categories, were also assessed.
For 4 indicators, only the denominators were fully computable, because the data items defining the quality of care measured in the numerator, such as the number of examined lymph nodes, were not available in a structured format.
The extent to which the set of items defines the variable, as described above, and fits the model is a measure of how well they provide construct validity, in other words, how well they measure a single, interpretable, underlying trait.
Although the correlation between Communication and Accommodation is high, we believe that the items defining the constructs are sufficiently unique to IPC measurement, and distinctly important enough to maintain as two separate constructs.
55 It includes the items defined by the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Statement.
The evaluation for asthma and the allergic disorders was based on the items defined by the International Study of Asthma and Allergies in Children (ISAAC) [ 1], of which the reliability and validity were proven.
Both conventional statistics and Rasch analysis suggest that the CBS is reliable and valid, and that the 10 items define a homogeneous construct.
