This study gathered descriptive data on 163 individuals who applied by telephone to a residential rehabilitation program for homeless veterans and compared these data with general veteran and homeless populations. Ss were a young (M = 40.82 years) and educated (M = 13.34 years of schooling) subgroup of homeless men (98.16%) with histories of relatively high, stable functioning (e.g., previous successful employment) and high rates of medical (47.47%), substance abuse (67.1%), psychiatric (41.93%; primarily nonpsychotic), and legal (71.15%) problems. These characteristics appear to be different from those of other subgroups of homeless (e.g., homeless chronically mentally ill, skid-row alcoholics), and they provide a basis for beginning to develop distinct remedial strategies that are specific to this subpopulation. The advantages of studying subgroups of homeless and the utility of the telephone interview data collection methodology are discussed.
