Many differences in screening characteristics were found between a) those screened who did not enroll in the program (N=188; 13%), b) those who enrolled into the program but who did not participate in the national evaluation (N=508; 36%), and c) those who agreed to participate in the evaluation (N=734; 51%) (Table 3). When compared with those screened but who did not enroll in the CICH program, those who enrolled were younger, more likely to be female; less likely to be black; and substantially more likely to have medical or mental health problems (Table 3). Since those enrolled into the program were more likely to have medical or mental health problems than those screened but not enrolled., "creaming", or selecting "healthier" people for enrollment into the program does not appear to have occurred.
Compared to those who enrolled but did not participate in the evaluation, those who enrolled into CICH and did participate in the evaluation were generally older, more likely to be male and black, far more likely to have medical or mental health problems (including higher rates of psychotic disorder or other serious mental illness) and to have alcohol abuse problems (Table 3). Moreover, participants in the evaluation were less likely to have been screened outdoors or at drop-in centers, and were more likely to be screened at soup kitchens or treatment programs.
Three months prior to the baseline assessment, the proportion of CICH clients who had spent at least one night in the nine housing arrangements examined were as follows: own place 29%; someone else's place 21%; hotel/SRO/boarding home 15%; halfway house 13%; transitional housing 12%; hospital 15%; jail 5%; shelter 53%; and, outdoors 43%. These percentages add up to greater than 100% because CICH clients lived in an average of 2.1 (sd=1.4) different housing arrangements during the 3-month period prior to the baseline assessment interview.
