Article: Availability of outpatient substance use disorder treatment programs in the United States.
[show abstract] [hide abstract]
ABSTRACT: The purpose of this study was to examine the availability of outpatient substance use disorder (SUD) treatment programs in the United States. A geographic information system (GIS) was used to spatially locate outpatient SUD treatment programs, calculate areas, and determine population density within specific areas. Urban areas were mapped using data from the US Census (2000). Addresses of outpatient SUD treatment programs were obtained from the Facility Locator Web site of the Substance Abuse and Mental Health Services Administration. A 15-mile service catchment around each outpatient SUD treatment program was drawn. The amount of urban area not covered by the service catchment represents the underserved. Total underserved urban area and population without access was computed for each state. Significant variability of underserved urban area and population was observed across the states. Moderate correlations among area and population suggest that some states are more effective in locating SUD treatment programs than other states.Substance Use & Misuse 06/2010; 45(7-8):1097-111. · 1.10 Impact Factor -
Article: Modeling the mental health effects of victimization among homeless persons.
[show abstract] [hide abstract]
ABSTRACT: Homeless persons are victims of violent and non-violent crime at higher rates than housed populations. While studies have suggested that victimization can induce or exacerbate mental health problems, there is very little known about factors that may buffer the effects of victimization. This cross-sectional study examined the influence of victimization on depressive symptoms in over 9600 homeless and mentally ill adults participating in the Access to Community Care and Effective Services and Supports study (ACCESS) conducted in multiple cities across the USA relationships between victimization, depressive symptoms, and perceived safety were tested within a structural equation modeling framework using data collected at the baseline interview. The overall model exhibited a good fit with the data. Non-physical victimization was associated with higher levels of depressive symptoms, and physical victimization was associated with lower levels of perceived safety. As hypothesized, perceived safety was a significant partial mediator of depressive symptoms. These results underscore the complexity of the relationships between victimization and depression in homeless adults and the importance of addressing different types of victimization in homeless and mentally ill adults.Social Science [?] Medicine 09/2008; 67(9):1475-9. · 2.70 Impact Factor
