NAPCRG abstracts 1977-1987: analysis of research designs and methods.

Research techniques reflect the approach of a discipline to the issues it faces. The annual North American Primary Care Research Group (NAPCRG) meeting has been a forum for family medicine research since 1973. A cross-sectional content analysis was conducted on all 1,295 printed NAPCRG abstracts from 1977 to 1987, classifying the research design and methods. The number of abstracts per meeting increased from 58 in 1977 to 149 in 1987. The predominant research design was cross-sectional (58%), followed by prospective (15%), experimental (15%), and retrospective (3%). The major methods were surveys (34%), chart reviews (24%), or surveys combined with chart reviews (7%). One fourth of all abstracts were cross-sectional surveys. NAPCRG research designs and methods have not changed substantially during these 11 years.
