Researchers from the California Department of Corrections conducted the study. The data came from three samples. The first was a department-wide census that included every female correctional officer working in the 11 California male inmate institutions. This sample provided baseline data from 386 female correctional officers. The second sample provided job performance data for 186 female corrections officers and sample of 168 male correctional officers matched for age and job tenure. This sample used only 7 of the 11 institutions, because 4 of the institutions employed fewer than 24 female officers. Twenty-four women and 24 men were selected from each of the 7 institutions. The third set of data came from a survey that used structured attitude questionnaires to collect information from 182 male and 59 female correctional officers and 400 inmates from 7 institutions. The research used a proportionate stratified random sample of correctional officers, using the seniority listing of the officers. The sample was stratified by sex and institution to be representative of all correctional officers in California. Ten percent of the officers in each stratum were selected. The inmate selection took place from 75 percent of the mainline inmates from a population of 25,838 male felons.
