Respondent-Driven Sampling: A New Approach to the Study of Hidden Populations
Authors: Heckathorn, Douglas
Journal Name: Social Problems
Publication Date: 1997
A population is "hidden" when no sampling frame exists and public acknowledgment of membership in the population is potentially threatening. Accessing such populations is difficult because standard probability sampling methods produce low response rates and responses that lack candor. This article introduces a new variant of chain-referral, respondent-driven sampling, that employs a dual system of structured incentives to overcome some the deficiencies of such ...

Respondent-Driven Sampling II: Deriving Valid Population Estimates from Chain-Referral Samples of Hidden Populations
Journal Name: Social Problems
Publication Date: 2002
...such as snowball & respondent-driven sampling. Though nonprobability methods succeed in accessing the hidden populations, they have been insufficient for statistical inference. This paper extends the respondent-driven sampling method to show that when biases associated with chain-referral methods are analyzed in sufficient detail, a statistical theory of the sampling process can be constructed, based on which the sampling process can be redesign...

..., and especially weight disparity. Some of these problems can be mitigated by a sample design that assures the independence between selection and individual respondent behaviour, but remaining difficulties, particularly weight variability, raise questions about how weighting should be used in this context.

Authors: V Joy Andres-Lemay; Ellen Jamieson; Harriet L MacMillan
Journal Name: Canadian journal of psychiatry
Publication Date: 2005

Authors: Dietz, T.L.
Journal Name: Journal of Social Service Research
Publication Date: 2011
This study's purpose was to identify the relationship between the annual incidence of drug and alcohol misuse among a national probability sample of 2,974 homeless individuals and self-reports of suicidal ideation and attempts while considering the predictors of both drug and alcohol misuse and suicidal ideation and attempts. By using a national dataset, the National Survey of Homeless Assistance Providers and Clients (NSHAPC), and testing a series of logistic models, this study allows...

Use of Faith-Based Social Service Providers in a Representative Sample of Urban Homeless Women
Authors: Heslin, Kevin; Andersen, Ronald; Gelberg, Lillian
Journal Name: Journal of Urban Health
Publication Date: 2003
There are few quantitative studies on the characteristics of homeless persons who use faith-based social service providers. To help address the lack of information in this area, we analyzed survey data on 974 participants in the University of California at Los Angeles (UCLA) Homeless Women’s Health Study, a representative sample of homeless women at shelters and meal programs in Los Angeles County. The primary objective of this analysis was to estimate the association of religious affiliation...

RESULTS: The response rate was 83%, and the final sample size was N=970. Sixty-eight percent of our sample reported receiving an HIV test in the past year, and 1.6% reported ever bei...

A probability sample of 301 homeless adults from Buffalo, NY, was followed over 6 months to document the utilization of a variety of community services, examine services desired, and identify factors associated with service utilization, preference, and satisfaction. The following needs were all rated as at least equally important as the need for affordable housing: safety, education, transportation, medical/dental treatment, and job training/placement (most of these needs were also rated...

Conclusions. These measures show promise for assessing AIDS knowledge and the efficacy of AIDS education programs in vulnerable populations. The findings reported here, however, are preliminary. Test-retest reliability needs to be examined, and additional studies are needed with samples that are more culturally diverse and include...

Proceedings of Statistics Canada’s Symposium 2001 - Achieving Data Quality in a Statistical Agency: A Methodological PerspectiveThe French survey of homeless people using support services is unique because of its scope and the conditions under which it was conducted. About 4,000 users of shelters and soup kitchens were surveyed in January and February 2001. Because some users move from one service point to another, it is necessary to collect precise data on the number of times each respondent...

Managed Care: Public-Sector Managed Behavioral Health Care: VI. The Iowa Approach to Profit and Community Reinvestment
Authors: Sabin, James; Daniels, Norman
Journal Name: Psychiatric Services
Publication Date: 2000
The public’s nightmare image of for-profit public-sector managed care is one of an opportunistic, financially driven company siphoning public money away from needy citizens to line the pockets of greedy investors and lavishly paid executives. A recent nationwide survey asked a random sample of adults if they were “worried that your health plan would be more concerned about saving money than about [providing] the best treatment for you if you are sick”. Sixty-one percent of respon...

Model Modifications in Covariance Structure Analysis: the Problem of Capitalization on Chance.
Authors: MacCallum, Robert C.; Roznowski, Mary; Necowitz, Lawrence B.
Journal Name: Psychological Bulletin
Publication Date: 1992
In applications of covariance structure modeling in which an initial model does not fit sample data well, it has become common practice to modify that model to improve its fit. Because this process is data driven, it is inherently susceptible to capitalization on chance characteristics of the data, thus raising the question of whether model modifications generalize to other samples or to the population. This issue is discussed in detail and is explored empirically through ...

Substance Abuse Disorders Among Runaway and Homeless Youth
Authors: Kipke, M. D. ; Montgomery, S. B. ; Simon, T. R. ; Iverson, E. F.
Journal Name: Substance Use and Misuses
Publication Date: 1997
This study used systematic sampling methods to recruit a sample of 432 homeless youth from both service and natural "hang-out" sampling sites. According to DSM-III criteria, the majority of respondents were classified as having an alcohol and/or illicit "drug abuse" disorder (71%). The results from multivariate logistic regression analyses indicate that cumulative length of time homeless is positively associated with risk for an "abuse" disorder. The implications of...

This article compares heterosexual and sexual minority street-involved youth across a number of sociodemographic, risk and current mental health, victimization and delinquency measures with a particular focus on gender differences. The sample consists of 147 homeless and street-involved young men and women aged 16-21 years in Toronto, Ontario, Canada. Bivariate analyses indicate that many of the differences between the heterosexual and sexual minority youth are driven by differences...
