The three studies that probably best estimated the extent to
which the gender of the individual may be a predictor of the occurrence of SIB
are the ones by Borthwick (1994), Borthwick et al. (1981), and Rojahn et al. (1999).
The first two were based on two different administrative data sets from California.
Rojahn et al. analyzed a combined California and New York data set. The prevalence
rates vary greatly across studies, and it seems that the global SIB prevalence
does not differ greatly between genders (see Table 3.4). The lower panel of Table
3.4 shows the relative prevalence of gender within the SIB samples. There does
seem to be a trend toward a higher representation of males in SIB samples, yet
that can easily be a function of uneven group sizes in the sampled population.
Comparisons of gender ratios within certain SIB topographies are not explored
