The seven multi-item scales were first contact and continuity (6 items); comprehensiveness (medical care) (4 items); comprehensiveness (social care) (3 items); first contact (access) (2 items); coordination (2 items); family centeredness (5 items); and community orientation (4 items).
A 5-point numerical rating scale was used (0 = not easy, 4 = very easy) to evaluate item accuracy, comprehensiveness and ease of response with an a-priori requirement of 3 points.
Procedures for developing the instrument encompassed three stages, 1. identification of important domains of the first-time father's experiences of childbirth and generation of items to represent the domains, 2. evaluation of comprehensiveness, comprehension and relevance of the items and 3. validation of the scales.
This study aimed to examine comprehension, comprehensiveness and relevance of items, and further to evaluate the usability and reliability of an interactive hypertension-specific mobile phone self-report system.
The aim of the study was to examine comprehension, comprehensiveness and relevance of items, and further to evaluate the usability and reliability of an interactive hypertension- specific mobile phone self-report system.
Nine items from the original scale were eliminated, because their secondary loadings were > 0.35: two items from first contact-accessibility, three items from original continuity, one item from original comprehensiveness, two items from original coordination, and one item from family centeredness.
Items and response formats were evaluated iteratively in a series of cognitive interviews in relation to their comprehension, comprehensiveness and relevance.
Important aspects are whether all items are relevant for the construct, aim, and target population and if no important items are missing (comprehensiveness) [ 14]. - Criterion validity: The extent to which scores on an instrument are an adequate reflection of a gold standard [ 8].
Collected views were used to revise items to develop comprehensiveness, feasibility, and understandability of the tool.
Regarding the comprehensiveness, all items presented to the children were correctly understood and therefore approved for further investigation in the preliminary version of our questionnaire.
