Under what assumptions do Site-by-Treatment instruments identify average causal effects?
So while both instruments identify a population of marginal students, these are not identical populations.
The paper provides a detailed description and evaluation of the instruments, identifies gaps in the literature, and provides suggestions for proper instrument selection, use, and development based on these findings.
For the second review step, all instruments identified in the first step were anonymized, and the original items were independently reviewed by two reviewers (WM and VG).
This study used a subsample of PRO instruments identified in a wider study assessing instrument quality.
For example, of five generic HRQL instruments identified, none were used in more than two studies.
Of the 34 instruments identified for inclusion, 30 were retrieved (Table 1).
Many instruments identified in this review were designed for administration by self report.
In 11 studies, instruments identified abused children only when they had clinical symptoms.
Manual searches based on reference lists and names of original instruments identified 12 additional records.
