Detail patient information based on the "Seven-Item Comprehensive Classification System" for osteomyelitis is presented in Table 1 [ 12].
As the addition of three psychosocial items significantly improves the performance of the triage tool at low cost, we advocate the implementation of this 8-item comprehensive set of items in routine obstetric care (see Additional file 2).
HRQOL is measured using the European Organisation for Research and Treatment of Cancer Quality of Life Core Questionnaire [ 35], a 30-item comprehensive health related quality of life assessment for cancer patients which yields a global QOL score, and five functional subscales (physical, emotional, social, role, cognitive).
Rather than using multi-item, comprehensive measures [ 30] about job satisfaction a single question (with scores ranging from 1 "Very dissatisfied" to 4 "Very satisfied") about overall current job satisfaction was employed because of the overlap of existing longer measures with the PES-NWI.
Model 4, intermediate set + 3 psychosocial items, together: comprehensive set of 8 items, x² = 199.9, p < 0.001.
The respondents had the opportunity to suggest new items and this did not led to identification of new items, thus suggesting that the initial pool of 20 items was comprehensive enough to describe the patients' experience of GP care.
Finally, the cognitive debriefing interviews confirmed that the SF-36v2 instructions and items were comprehensive and understandable without change and the response choices and recall period were appropriate for use with patients with AL amyloidosis.
Cognitive debriefing interviews confirmed the relevance of the concepts measured by the SF-36v2 and indicated that patients found the SF-36v2 both easy to understand and complete, that the SF-36v2 instructions and items were comprehensive and understandable without change, and the response choices and recall period were appropriate for use with patients with AL amyloidosis.
Therefore, in developing a valid instrument an important aim is that the list of items is comprehensive.
With limited-item or comprehensive household food inventories (HFIs), most researchers document household availability at a single point in time [ 20, 22, 40, 43, 54, 57, 62, 63].
