Most had some self reported EKG exposure prior to the course, with 11/13 (84%) using books and 5/13 (39%) during clinical rounds (table 1).
In the third phase (from July 2011), the presence of oppositional defiant disorder, conduct disorder, and substance use disorders other than alcohol and marijuana, was no longer assessed, and some self-report questionnaires were no longer administered to the youths (e.g., self-reported offending).
Some self-report measures have been validated and are thus feasible for use in large studies but the method is prone to misclassification and might not capture the type and true intensity of the physical exercise it is aimed to measure, leading to attenuated risk estimates.
Some self-report measures were based on conceptual frameworks proposed by the author(s) of the measure.
With the exception of some self-report questionnaires, most assessments are conducted in face-to-face contacts.
Certainly, screening tools and questionnaires vary widely in quality and comprehensiveness, and some self-report questionnaires possess fairly robust psychometric properties [ 28].
Some self-report instruments incorporate various weighting systems for this purpose and two of these have been validated in hospitalized populations [ 15, 18].
In addition to comparing outcomes pre/post clinic enrollment, where possible, these outcomes will be compared to those of two matched control groups, and for some self-report measures, to regional and national data.
There was verification of some self-reports by interviewer observation.
The outcome measures include some self-reports and therefore participants who are unable to complete these cannot be included.
Some self-reports are probably influenced by lack of memory, which would influence the stability of the responses in a negative way.
