Studies of overall health in a specific sample must therefore use several health indexes measuring different domains of health.
15 The index is a UK census based (2001) small area statistic measuring different domains of deprivation.
BRIEF-A is a 75-item self-report questionnaire that provides 9 subscales measuring different domains of cognitive control: 1) inhibit, 2) Shift, 3) Emotional Control, 4) Self-Monitor, 5) Initiate, 6) Working Memory, 7) Plan/Organize, 8) Task Monitor, and 9) Organization of Materials.
The Cystic Fibrosis Questionnaire (CFQ) is a widely used disease specific questionnaire which measures different domains of health-related quality of life [ 12- 15].
Although these questionnaires are designed to measure different domains of the QOL such as pain, physical, emotional, and social functioning, the original authors have not investigated the dimensionality and structure of the domains or items via factor analysis.
Therefore, standard DIF analysis indicated that Walking items and CLP items measured different domains and DIF/DBF analysis revealed that Walking was the core dimension of the mobility construct and CLP was a secondary dimension that produced DBF.
Therefore, our findings corroborate the hypothesis of the aforementioned authors that these instruments measure different domains of quality of life with distinct constructs.
Although it seems unusual to combine items that measure different domains of the disease, this approach reflects the belief that AD, prior to dementia, is a single entity that can be measured with a single combination score.
These data, collected from direct observation, were combined with tax assessor, public safety, and U.S. Census data to construct indices measuring different built environment domains.
It consists of 36 questions grouped into 8 domains measuring different aspects of QoL (Physical Functioning (PF), Role Physical (RP), Bodily Pain (BP), General Health (GH), Vitality (VT), Social Functioning (SF), Role Emotional (RE), Mental Health (MH)).
In this study, multiple factors measuring different aspects of the sociocultural domain were identified, including aspects of peer, teacher and parental influences.
