“…At least a third of homeless people are veterans (Rosenheck et al, 1989), but we recognize that homeless veterans in the HCMI program are not representative of the entire homeless population. Most notably, our sample included few women and no children or adolescents.…”

“…As perhaps one third of homeless people served in the military (Rosenheck et al, 1989), describing homeless veterans is an essential part of building a comprehensive picture of the homeless population. Our substantive results, when interpreted in the context of other taxonomic homelessness research conducted in different samples and settings, will also help us gauge whether subtypes of homeless people found in other studies were idiosyncratic to those investigations or are prevalent across settings and samples.…”

“…Participants were drawn from nine sites across the country that were participating in a national evaluation of the Department of Veterans Affairs Homeless Chronically Mentally IU Program (HCMI; see Rosenheck et al, 1989, for a description of the mission and activities of the HCMI program). From December 7, 1987to October 15, 1988, staff at the nine sites had at least minimal contact with 1,748 homeless veterans.…”

To identify subgroups within the homeless population, a number of researchers have employed cluster analytic statistical procedures. Although this is an appropriate application of cluster anMysis, many studies have not employed important statistical safeguards against arbitrary results. This study demonstrates a cluster analytic procedure--sequential validation--that enhances the replicability, external validity, and cross-validity of cluster solutions. The procedure is applied to a nationwide sample of 745 homeless veterans. After 12 different clustering procedures were subjected to derivation, replication, external validation, and cross-validation phases, a 4-cluster Ward solution emerged as the most sound. Substantively, the clusters were an alcoholic subtype, a psychiatrically impaired subtype, a best functioning subtype, and a multiproblem subtype. The'generalizability of these subgroups to other contexts was assessed by comparing them to subgroups identified in other homelessness research. Suggestions were made for improving the quality of cluster anal, tic research in community psychology.

“…In the first nationwide study completed in a decade, 744,000 homeless persons were found at a single point in time in 2005, and far more persons experience homelessness in the course of a year (Research reports on homelessness: Homelessness counts, 2007). In addition to systemic factors (e.g., low-cost housing availability) and individual factors (e.g., severe mental illness), substance abuse augments the risk for both homelessness (Corrigan & Anderson, 1984;Koegel, Burnam, & Farr, 1988;Rosenheck et al, 1989) and major health problems (Martens, 2001;Plumb, 1997;Smereck & Hockman, 1998).…”

In a randomized controlled trial, behavioral day treatment, including contingency management (CM+), was compared to contingency management components alone (CM). All 206 cocaine-dependent homeless participants received a furnished apartment with food and work training/employment contingent on drug-negative urine tests. CM+ also received cognitive-behavioral therapy, therapeutic goal management, and other intervention components. Results revealed that CM+ treatment attendance and abstinence were not significantly different from CM during 24 weeks of treatment. After treatment and contingencies ended, however, CM+ showed more abstinence than CM, indicating a delayed effect of treatment from 6 to 18 months. CM+ had more consecutive weeks abstinent across 52 weeks, but not during active treatment. We conclude that CM alone may be viable as initial care for cocaine-dependent homeless persons. That CM+ yields more durable abstinence indicates that it may be appropriate as stepped-up care for clients not responding to CM (Clinical Trials.gov, no. NCT00368524).
