[Study on health related quality of life based on information from COOP/WONCA sheets]

The main objective of this study is to describe the quality of life related to health (QLRH) in primary health patients, in escorts of primary health care patients, in pregnant women, in relatives caring for Alzheimer patients, and in drug addicts.

The sample consists of 1,408 persons: primary health care patients (n = 475), escorts of primary health care patients (n = 200), in pregnant women (n = 510), in relatives caring for Alzheimer patients (n = 169), and in drug addicts (n = 68). The QLRH has been measured according to the Spanish version of the COOP/WONCA charts. The questionnaire was filled directly by the people surveyed.

The group of pregnant women is the group less physically fit but at the same time the group with best health status, higher social support and best quality of life. At the other end, the group of addicts is the worst considered group regarding the variables of feelings, social activities and quality of life. The factor analysis shows a unifactor structure and its internal consistency is 0.79 (Cronbach's alpha). The multiple regression of COOP/WONCA charts over the variables of age, sex and study groups explains the 14% of the variance (r2 = 0.14).

The COOP/WONCA charts allow for the establishment of distinctions in some of the groups studied (pregnant women and drug addicts), but do not establish enough differences with respect to other groups, which may be due to a certain homogeneity among them. The use of a global score for the COOP/WONCA charts would be theoretically and methodology feasible.
