Objective:
To determine the frequency and the main methodological characteristics of the epidemiological designs used in the research studies published in the journal Atencion Primaria between 1984 and 1990.
Design:
A descriptive study.
Material:
Included are all the articles presenting data produced by the authors themselves in the context of a research study and published in the sections of original articles, special contributions or clinical notes in the issues of the journal Atencion Primaria between 1984 and 1990.
Measurements And Main Results:
A data-gathering questionnaire was used, whose concordance was previously assessed blindly by two observers. There were 324 articles included. Of these, 93% were descriptive studies, out of which 27% were prevalence studies. Of these prevalence studies, 15.7% were conducted among the population as a whole. A questionnaire, which had been previously validated in 47.7% of cases, was used in 13.5% of the studies. Experimental research accounted for 21 studies (6.5%), of which 85% had an explicit control group.
Conclusions:
Only a small proportion are analytical studies. The majority of descriptive studies are carried out among the population attending for treatment.
