Deconstructing the 'cheque effect': short-term changes in injection drug use after receiving income assistance and associated factors

BACKGROUND AND AIMS

Disbursement of income assistance has been temporally associated with intensified drug use and related harms (coined the 'cheque effect'). However, relationships to injection drug use (IDU) remain understudied. We examined short-term 'cheque effects' and associated factors among people who inject drugs (PWID).

DESIGN

Cross-sectional analysis nested within a cohort study.

SETTING

Montreal, Quebec, Canada.

PARTICIPANTS

PWID receiving income assistance, with no employment income. A total of 613 PWID (median age 41, 83% male) contributed 3269 observations from 2011 to 2017.

MEASUREMENTS AND METHODS

At each cohort visit, an interviewer-administered questionnaire captured retrospective reports of injection-related behaviour during the 2-day periods (i) before and (ii) including/after receiving last month's income assistance payment (number of injections; drugs injected; any receptive syringe-sharing). The relative likelihood (odds) and magnitude (rate) of an increase in injection frequency ('cheque effect') were estimated in relation to social and behavioural factors using logistic and negative binomial regression in a covariate-adjusted two-part model.

FINDINGS

Prevalence of IDU and syringe-sharing were, respectively, 1.80 and 2.50 times higher in the days following versus preceding cheque receipt (P < 0.001). Among people with past-month IDU, most observations showed increased injection frequency (52%) or no change in injection frequency (44%). The likelihood of a 'cheque effect' was positively associated with cocaine injection [versus injection of other substances, odds ratio (OR) = 2.639, 95% confidence interval (CI) = 2.04-3.41], unstable housing (OR = 1.272, 95% CI = 1.03-1.57) and receiving opioid agonist therapy (OR =1.597, 95% CI = 1.27-2.00) during the same month. Magnitude of the 'cheque effect' was positively associated with cocaine injection [rate ratio (RR) = 1.795, 95% CI = 1.43-2.16], unstable housing (RR = 1.198, 95% CI = 1.02-1.38) and frequent injection (RR = 2.938, 95% CI = 2.43-3.44), but inversely associated with opioid agonist therapy (RR = 0.817, 95% CI = 0.68-0.95) and prescription opioid injection (RR = 0.794, 95% CI = 0.66-0.93).

CONCLUSION

Among people who inject drugs in Montreal, Canada, injection drug use and receptive syringe-sharing appear to be more prevalent in the 2 days after versus before receiving income assistance. The odds and rate of individual-level increases in injection frequency appear to be positively associated with cocaine injection (versus injection of other substances) and unstable housing.

Increasing Overall Well-Being is Salient in Treating Homelessness

Homeless treatment programs have focused on physical solutions rather than attending to all aspects of well-being. Support services that address overall well-being have demonstrated effectiveness. Previous research suggests that overall well-being is defined as satisfaction within all life spheres. Objective life indices have been the primary evidence of success among various programs, which include food, housing, income, leisure, health, access to psychiatric and medical services, and maintenance of positive support networks. This does not account for other important subjective components, such as psychiatric symptoms and quality of life. This study was designed to assess quality of life and psychiatric symptoms among the people who were chronically and formerly chronically homeless. The people who were formerly chronically homeless are defined as individuals who were chronically homeless in the past but have successfully remained in housing for 6 months or more and have access to intensive case management services. People who are chronically homeless are homeless individuals who have lacked a residence for a year or more or have had four or more episodes in three years, are single, and have a persistent disability. Participants completed the Oxford Happiness Scale, Brief Symptom Inventory, and a brief questionnaire. All participants were disabled in accordance with the definition of chronic homelessness adopted by the U.S. Department of Housing and Urban Development. This researcher hypothesized that high quality-of-life scores, low frequency of psychiatric symptoms, and greater access to basic life indices indicate happiness overall. Additionally, it was hypothesized that people who are chronically homeless have a higher foster care rate than the general population.

Access to housing subsidies, housing status, drug use and HIV risk among low-income U.S. urban residents

BACKGROUND

Much research has shown an association between homelessness and unstable housing and HIV risk but most has relied on relatively narrow definitions of housing status that preclude a deeper understanding of this relationship. Fewer studies have examined access to housing subsidies and supportive housing programs among low-income populations with different personal characteristics. This paper explores personal characteristics associated with access to housing subsidies and supportive housing, the relationship between personal characteristics and housing status, and the relationship between housing status and sexual risk behaviors among low-income urban residents.

METHODS

Surveys were conducted with 392 low-income residents from Hartford and East Harford, Connecticut through a targeted sampling plan. We measured personal characteristics (income, education, use of crack, heroin, or cocaine in the last 6 months, receipt of welfare benefits, mental illness diagnosis, arrest, criminal conviction, longest prison term served, and self-reported HIV diagnosis); access to housing subsidies or supportive housing programs; current housing status; and sexual risk behaviors. To answer the aims above, we performed univariate analyses using Chi-square or 2-sided ANOVA's. Those with significance levels above (0.10) were included in multivariate analyses. We performed 2 separate multiple regressions to determine the effects of personal characteristics on access to housing subsidies and access to supportive housing respectively. We used multinomial main effects logistic regression to determine the effects of housing status on sexual risk behavior.

RESULTS

Being HIV positive or having a mental illness predicted access to housing subsidies and supportive housing, while having a criminal conviction was not related to access to either housing subsidies or supportive housing. Drug use was associated with poorer housing statuses such as living on the street or in a shelter, or temporarily doubling up with friends, acquaintances or sex partners. Living with friends, acquaintances or sex partners was associated with greater sexual risk than those living on the street or in other stable housing situations.

CONCLUSIONS

Results suggest that providing low-income and supportive housing may be an effective structural HIV prevention intervention, but that the availability and accessibility of these programs must be increased.

Structural and Personal Factors Related to Access to Housing and Housing Stability among Urban Drug Users in Hartford, Connecticut

Several policies criminalizing drug use significantly impact drug users' access to housing. This article explores the impact of housing policies on active drug users' access to housing and structural and personal factors related to their homelessness and housing stability. Qualitative interviews were conducted with 65 active cocaine or heroin users at baseline, three and six months. Participants were purposively sampled to reflect a variety of housed and homeless statuses. Interviews were analyzed to explore the processes associated with changes in housing status. Factors that led to homelessness included arrest, eviction, absence of housing subsidies, and lack of social support. Participants reported being evicted, and losing housing subsidies, welfare entitlements, and important social relationships following arrest. Criminal histories also limited their ability to find employment and permanent housing. Factors that led to housing stability included having family support, housing subsidies, and social supportive services. Active drug users can maintain independent housing when provided appropriate structural supports including rental subsidies and social services. But arrest disrupts drug users' housing stability. Programs to appropriately house those released from jail could help decrease homelessness among this population.

Unofficial policy: access to housing, housing information and social services among homeless drug users in Hartford, Connecticut

BACKGROUND

Much research has shown that the homeless have higher rates of substance abuse problems than housed populations and that substance abuse increases individuals' vulnerability to homelessness. However, the effects of housing policies on drug users' access to housing have been understudied to date. This paper will look at the "unofficial" housing policies that affect drug users' access to housing.

METHODS

Qualitative interviews were conducted with 65 active users of heroin and cocaine at baseline, 3 and 6 months. Participants were purposively sampled to reflect a variety of housing statuses including homeless on the streets, in shelters, "doubled-up" with family or friends, or permanently housed in subsidized, unsubsidized or supportive housing. Key informant interviews and two focus group interviews were conducted with 15 housing caseworkers. Data were analyzed to explore the processes by which drug users receive information about different housing subsidies and welfare benefits, and their experiences in applying for these.

RESULTS

A number of unofficial policy mechanisms limit drug users' access to housing, information and services, including limited outreach to non-shelter using homeless regarding housing programs, service provider priorities, and service provider discretion in processing applications and providing services.

CONCLUSION

Unofficial policy, i.e. the mechanisms used by caseworkers to ration scarce housing resources, is as important as official housing policies in limiting drug users' access to housing. Drug users' descriptions of their experiences working with caseworkers to obtain permanent, affordable housing, provide insights as to how access to supportive and subsidized housing can be improved for this population.

The Probable Impacts of the Removal of the Addiction Disability Benefit in Ontario

In Ontario, those dependent on substances are no longer eligible for welfare payments based on an addiction disability. While the impact of this program has not been assessed, evidence from a similar policy shift in the USA suggests deleterious effects on the health and social functioning of about half of those who lose this form of social support. A review of the research on the chronic-illness view of addiction, the fostering of stigma by exclusionary social policies, and the negative effects on mental health and homeless status associated with the loss of welfare benefits leads to the conclusion that this is an ill-advised policy for Ontario. Its continuation there, and its extension to other provinces, is not recommended.

Long-term effects of syringe exchange on risk behavior and HIV prevention

The purpose of this study was to assess stability of population-level injection risk behavior over time among participants in a syringe exchange program and compare factors affecting syringe sharing at two points in time. Participants of the Tacoma Syringe Exchange Program were interviewed in 1997 and 2001 using audio computer assisted self-interviewing technology. In each wave of data collection, a random cross section of participants was recruited and interviewed, with no attempt made to follow respondents over time. Rates of injection risk behavior remained stable across the 4-year period, despite increases in factors associated with syringe sharing. Homelessness, rates of depression symptoms, and injection of amphetamines all increased from 1997 to 2001. The central factors associated with syringe sharing in both 1997 and 2001 were depression symptoms and the interaction of younger age with amphetamine injection. The data indicate that the exchange has been able to stabilize risk among a high-risk population for a substantial period of time. This study confirms previous findings that SEPs can play a significant role in the prevention of HIV in marginal and impoverished communities in the United States.

Working it out: development and testing of a multimedia, vocational education program

A self-administered, CD-ROM-based, interactive multimedia psychoeducational intervention, called Working It Out, was developed to improve employment functioning for clients in substance dependency treatment. The computer-based, program's effectiveness was tested in comparison with printed material. During 2000--2001 194 clients with employment concerns in six treatment programs were randomly assigned to a CD-ROM or print material condition and evaluated at baseline and 6 months later. A main effect for improvement was observed on employment indices, but there was no condition-by-time interaction. Results suggest that clients are willing and able to use vocational rehabilitation information presented in any format, although the CD-ROM-based program received significantly better satisfaction ratings than did the print material.
