The magnitude of variation in reported rates of self-injury suggests that factors other than actual incidence affect these rates. Factors that relate to the scope of the reporting network & to the intensity of contacts within this network are examined to determine their effect on the reporting process. Differences in study design & reporting procedures are found to explain most of this variation and suggest the need for stadardized techniques in studying the epidemiology of self-injury.
