Consequently, each sub-dimension is defined by the mean of the summarized items of that sub-dimension.
The while-testing phase lasted 20 minutes and it contained two wh- and summarizing items each, MC, true/false and guessing items.
The computation of HRQOL subscale scores (mental, social, physical, psychological functioning as well as emotional well being) was based on the QOLIE-31 manual for summarizing items using empirical derived weight.
Outcome variables were pain, walking capacity, flexion, Harris Hip Score (HHS), a composite score summarizing items of pain, mobility, motion and some activities of daily living into a sum score from 0-100, [ 16] as well as intraoperative, systemic and local complications.
Secondly, we summarized items on knowledge by infection and/or based on results from univariate analysis, resulting in four categories: general knowledge on HIV transmission and treatment (I6-8, I11-15); specific knowledge on HIV (I9-10), knonledge on hepatitis (I1-5) and knowledge on STI I16-200).
Table 2 summarizes item status for each survey instrument throughout Phases I and II.
XSL is thereby employed for setting parameters such as page size and margins, for counting and enumerating elements, and for assembling a preamble page that summarizes item frequencies.
We found no substantial differences between them, indicating that summarizing item responses by subscales and summary components is appropriate to monitor person-level change.
The movement to summarize these items in reliable and consistent scales fills a variety of needs.
The site allows for free, anonymous, online administration of the survey, with survey administrators receiving summarized and item-by-item results.
