In systematic reviews of studies of patients' values and preferences, the objective of the study was to summarize items and domains authors have identified when considering the risk of bias (RoB) associated with primary studies.
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.
Amongst the topics covered are: essay rating, summarizing item-level properties, equating of tests, small-area estimation, and incomplete longitudinal studies.
Table 2 summarizes item status for each survey instrument throughout Phases I and II.
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 site allows for free, anonymous, online administration of the survey, with survey administrators receiving summarized and item-by-item results.
At the end of a discussion around a question, the investigator summarized the items that were mentioned and asked patients if there were items they could think of that had not yet been mentioned.
