Domains & categories (#)
Name of categories/domains
Adult COOP: physical function, emotional function, daily activities, social activities, social support, change in health, overall health, pain, quality of life (Nelson, Landgraf, et al.; Nelson, Wasson, Johnson et al.). Adolescent COOP: physical fitness, emotional feelings, school work, social support, family communication, health habits (Nelson, Wasson, Johnson et al.; Wasson, Kairys, Nelson et al.). COOP/WONCA: physical fitness, emotional feelings, daily activities, social activities, change in health, overall health, pain (optional) (Landgraf et al., Van Weel).
Scaling of items
5-point Likert-type scaling, with descriptors and cartoon illustrations of levels 1 through 5. Rating of "1" = no impairment, "5" = most impaired. Contribution of illustrations has been explored (Kempson et al., Larson et al.)
Each chart is a direct indicator of function in the domain, and summing for a total score is not encouraged. Scores can be summed for research purposes (Van Weel).
Evidence for convergent and discriminant validity found for physical and emotional (but not role function) charts in multi-trait multi-method matrix with the Rand general health questionnaire (Nelson, Wasson, Kirk et al). Six COOP charts discriminated between levels of function in groups of patients, but were less precise than long-form (MOS), short-form (SF-36), and multi-item/global (General Health Survey) measures (McHorney et al.). Evidence for concurrent validity of COOP/WONCA charts with SF-36, EuroQol, and Nottingham Health Profile found through correlation and factor analysis; 4 of 6 charts discriminated between known groups (Essink-Bot et al.). Evidence for concurrent validity of adolescent COOP charts reported (Wasson, Kairys et al.)
