For each of the 30 selected abstracts, we obtained 1 abstract without a limitations section (i.e., the original abstract) and 1 with a limitations section (i.e., the original abstract plus the constructed limitations section).
However, in the project team's field data collection, which was dependent on the staff and resources of the DSHS, the use of multiple items to measure the same construct (activity limitations) was not feasible.
Principal components analysis revealed a four-factor structure representing the constructs of functional limitation, pain intensity, concern with appearance and activity restriction, which explained 60.8% of the variance, with 38.9% of the variance explained by the first construct (functional limitation).
This requires a functional outcome measure that is unidimensional (measures the single construct of activity limitations), psychometrically sound, relevant to the patient and clinically feasible.
None of the currently used outcome measures in people with a proximal humeral fracture [ 14] measure the single construct of activity limitations.
Nineteen items were uniquely related to the activity limitations construct; 15 items from the main section of the DASH and two from each optional section.
"A rock so big that he can't lift it" is a logically incoherent construct, not a limitation on God's power.
The activity of each promoter construct under nitrogen limitation was determined in vivo, in a lambda phage lacZ reporter system integrated as a single-copy lysogen to avoid titrating NtrC or polymerase.
The majority of response problems were judged to be present within the activity limitation construct (Table 3).
Instead of conducting a detailed quality appraisal of individual studies, we examined study methodology and generic study design limitations, including self-reported generic limitations, to construct a collective assessment of study quality.
