Client Engagement in Legally-Mandated Addiction Treatment: A Prospective Study Using Self-Determination Theory.

OBJECTIVE: Mixed evidence on the effectiveness of using legal referrals to leverage treatment participation may reflect unmeasured variability in client motivations for seeking care. We hypothesized that associations between legal referral and client engagement would be moderated by reasons that clients sought treatment, as conceptualized by self-determination theory (SDT). METHODS: Adults entering a Western Canadian residential addiction treatment program (N=325; 49.2% male; 54.5% First Nations, Métis, or Inuit; 15.1% legally referred; M age=32.9 years, range=18-63, SD=10.3) rated the extent to which treatment was being sought because of coercive social pressures (external motivation; α=.85), guilt and shame about continued substance misuse (introjected motivation; α=.82), or a valued commitment to the goals of the program (identified motivation; α=.91). Six weeks later, clients rated their level of cognitive involvement in treatment (83.4% completion rate); chart reviews assessed retention status and number of days retained until drop-out. RESULTS: Multivariable Cox regression and logistic regression analyses showed that legally-mandated clients who reported low admission levels of identified or external treatment motivation were most likely to exhibit early dropout. Legally-mandated clients who reported high admission levels of introjected motivation were most likely to be retained in treatment with high cognitive involvement. CONCLUSIONS: SDT provides a useful framework for describing how associations between legal referral and client engagement in treatment vary, depending on their reasons for seeking care.

Does the redesign of a psychiatric inpatient unit change the treatment process and outcomes?

OBJECTIVE: This study investigated whether ward atmosphere mediated the associations between the physical and therapeutic characteristics of an inpatient ward and patient outcomes. METHODS: Individuals (N=290) receiving inpatient care for mood and anxiety disorders before and after an extensive renovation project were surveyed about ward atmosphere, quality of life, and treatment satisfaction. Global functioning at admission and discharge and other clinical characteristics were obtained from patients' charts. RESULTS: After the redesign, participants perceived improved ward atmosphere, and the improvement was associated with greater treatment satisfaction and quality of life. Change in global functioning was independent of ward atmosphere. CONCLUSIONS: Efforts to improve the inpatient environment by supporting patient autonomy, peer support, and practical skill development may be expected to meet with improved outcomes, at least for quality of life and satisfaction with treatment. These findings are consistent with patient-centered design as well as with broader perspectives on recovery-oriented services.

Rasch model of the GAIN substance problem scale among Canadian adults seeking residential and outpatient addiction treatment.

BACKGROUND: The GAIN Substance Problem Scale (SPS) measures alcohol and drug problem severity within a DSM-IV-TR framework. This study builds on prior psychometric evaluation of the SPS by using Rasch analysis to assess scale unidimensionality, item severity, and differential item functioning (DIF). METHODS: Participants were attending residential or outpatient treatment in Alberta and Ontario, Canada, respectively (n=372). Rasch analyses modeled a latent problem severity continuum using SPS scores at treatment admission and 6-week follow-up. We examined DIF by gender, treatment modality (outpatient vs. residential), and assessment timing (baseline vs. follow-up). RESULTS: Model fit was good overall, supporting unidimensionality and a single underlying continuum of substance problem severity. Relative to person severity, however, the range of item severities was narrow. Items were too severe for many clients to endorse, particularly at follow-up. Overall, the rank order of item severities was stable across gender, treatment modality, and time point. Although traditional Rasch criteria indicated a number of statistically significant and substantive DIF estimates across modality and time points, effect size indices did not suggest a net effect on total scale scores. CONCLUSIONS: The analysis broadly supports use of the SPS as an additive measure of global substance severity in men and women and both residential and outpatient settings. Although DIF was not a major concern, there was evidence of item redundancy and suboptimal matching between items and persons. Findings highlight potential opportunities for further improving this scale in future research and clinical applications of the GAIN.

Evidence from regression-discontinuity analyses for beneficial effects of a criterion-based increase in alcohol treatment.

Brief interventions effectively reduce alcohol problems; however, it is controversial whether longer interventions result in greater improvement. This study aims to determine whether an increase in treatment for people with more severe problems resulted in better outcome. We employed regression-discontinuity analyses to determine if drinking driver clients (n = 22,277) in Ontario benefited when they were assigned to a longer treatment program (8-hour versus 16-hour) based on assessed addiction severity criteria. Assignment to the longer16-hour program was based on two addiction severity measures derived from the Research Institute on Addictions Self-inventory (RIASI) (meeting criteria for assignment based on either the total RIASI score or the score on the recidivism subscale). The main outcome measure was self-reported number of days of alcohol use during the 90 days preceding the six month follow-up interview. We found significant reductions of one or two self-reported drinking days at the point of assignment, depending on the severity criterion used. These data suggest that more intensive treatment for alcohol problems may improve results for individuals with more severe problems.

Client-centered design of residential addiction and mental health care facilities: staff perceptions of their work environment.

In this article we discuss the findings from a series of focus groups conducted as part of a 3-year, mixed-method evaluation of clinical programs in a large mental health and substance use treatment facility in Canada. We examined the perceptions of clinical personnel on the physical design of new treatment units and the impact on service delivery and the work environment. The new physical design appeared to support client recovery and reduce stigma; however, it brought certain challenges. Participants reported a compromised ability to monitor clients, a lack of designated therapeutic spaces, and insufficient workspace for staff. They also thought that physical design positively facilitated communication and therapeutic relationships among clinicians and clients, and increased team cohesion. We suggest that, from these findings, new avenues for research on achieving the important balance between client and staff needs in health facility design can be explored.

Influence of co-occurring mental and substance use disorders on the prevalence of problem gambling in Canada.

CONTEXT/BACKGROUND: Research has shown that problem gambling (PG) is associated with substance use disorders (SUD) and also with other mental disorders (MD). Nevertheless, evidence about the relative contribution of each type of disorder for the risk of gambling in the population is very limited. OBJECTIVE: Study the association of SUD, alone and in combination with MD, with the prevalence and severity of PG. DESIGN: Cross-sectional national survey (Canadian Community Health Survey-Mental Health and Well-Being) data collected through a multi-stage stratified cluster design. SETTING: Population-based household survey. PARTICIPANTS: This analysis includes data on 36 885 participants (99.7% of the survey sample). MAIN OUTCOME MEASURES: The prevalence and severity of PG were measured using the Canadian Problem Gambling Index. Prevalence of MD (mood and anxiety disorders) and SUD were defined according to the World Mental Health Survey Initiative Composite International Diagnostic Interview, following definitions of the DSM-IV. RESULTS: Compared to the population, higher prevalence rates of PG are observed when the severity of SUD is higher, but are not impacted by the co-occurrence of MD. For individuals with low risk and moderate risk/problem gambling, the prevalence rate difference (prevalence rate in the subgroup minus prevalence rate in the population) observed among substance dependents was reduced when MD co-occurred (from a prevalence rate difference of 2.5; 99% confidence interval 1.6-3.8 to 1.6; 99% confidence interval 1.2-2.2 for low risk gamblers and from 3.7; 99% confidence interval 1.6-5.5 to 2.9; 99% confidence interval 2.0-4.3 for moderate risk/problem gamblers). Estimates were not statistically different. CONCLUSIONS: Prevalence of all levels of PG increased with SUD severity, but the pattern did not appear to be affected by MD co-occurrence. Results suggest particular attention be given to SUD in treatment-seeking clients with co-occurring disorders.

Alcohol factors in suicide mortality rates in Manitoba.

OBJECTIVE: To identify alcohol-related factors that influence mortality rates from suicide. METHOD: We examined the impact of per capita consumption of total alcohol, spirits, beer, and wine; unemployment rate; and Alcoholics Anonymous (AA) membership rate on total, male and female suicide mortality rates in Manitoba during 1976 to 1997. Time series analyses with autoregressive integrated moving average modelling were applied to total, male and female suicide rates. The analyses performed included total alcohol consumption, spirits consumption, beer consumption, and wine consumption. Missing AA membership data were interpolated with cubic splines. RESULTS: Total alcohol consumption, and consumption of beer, spirits, and wine individually, were significantly and positively related to female suicide mortality rates. Spirits and wine were positively related to total and male mortality rates. AA membership rates were negatively related to total and female suicide rates. Unemployment rates were positively related to male and total suicide rates. CONCLUSIONS: The data confirm the important relations between per capita consumption measures and suicide mortality rates. Additionally, the results for AA membership rates are consistent with the hypothesis that AA membership and alcohol abuse treatment can exert beneficial effects observable at the population level.

Perceived unmet need for mental health care for Canadians with co-occurring mental and substance use disorders.

OBJECTIVE: Previous analyses demonstrated an elevated occurrence of perceived unmet need for mental health care among persons with co-occurring mental and substance use disorders in comparison with those with either disorder. This study built on previous work to examine these associations and underlying reasons in more detail. METHODS: Secondary data analyses were performed on a subset of respondents to the 2002 Canadian Community Health Survey (unweighted N=4,052). Diagnostic algorithms classified respondents by past-year substance dependence and selected mood and anxiety disorders. Logistic regressions examined the associations between diagnoses and unmet need in the previous year, accounting for recent service use and potential predisposing, enabling, and need factors often associated with help seeking. Self-reported reasons underlying unmet need were also tabulated across diagnostic groups. RESULTS: Of persons with a disorder, 22% reported a 12-month unmet need for care. With controls for service use and other potential confounders, the odds of unmet need were significantly elevated among persons with co-occurring disorders (adjusted odds ratio=3.25; 95% confidence interval=1.96-5.37). Most commonly, the underlying reason involved a preference to self-manage symptoms or not getting around to seeking care, with some variation by diagnosis. CONCLUSIONS: The findings highlight potential problems for individuals with mental and substance use disorders in accessing services. The elevated occurrence of perceived unmet need appeared to be relatively less affected by contact with the health care system than by generalized distress and problem severity. Issues such as stigma, motivation, and satisfaction with past services may influence help-seeking patterns and perceptions of unmet need and should be examined in future work.

The interaction of co-occurring mental disorders and recovery management checkups on substance abuse treatment participation and recovery.

This article examines the effectiveness of quarterly Recovery Management Checkups (RMCs) for people with substance disorders by level of co-occurring mental disorders (34% none, 27% internalizing disorders, and 39% internalizing and externalizing) across two randomized experiments with 92% to 97% follow-up. The 865 participants are 82% African American, 53% female, and age 37 on average. RMC involves identification of those in need of treatment, motivational interviews, and treatment linkage assistance. It is effective in linking participants in need to treatment, with equal or better outcomes among those with more mental disorders. The data support the utility of monitoring and re-intervention for clients with co-occurring disorders.

Use of mental health care services by Canadians with co-occurring substance dependence and mental disorders.

OBJECTIVES: This study contributes to knowledge of the processes underlying help seeking by those with mental and substance use disorders by examining relationships among need, service use, and satisfaction with mental health care in a population-based sample. METHODS: Secondary data analyses were performed on responses to the 2002 Canadian Community Health Survey (N=36,984). Diagnostic algorithms classified respondents by past-year diagnostic status, including substance dependence and selected mood and anxiety disorders. Logistic regressions examined associations between diagnostic status and service use, satisfaction, and unmet need for care. RESULTS: Ten percent of Canadians and 39% of Canadians with a mental disorder or substance dependence sought services in the year preceding data collection. Although those with co-occurring substance dependence and mental disorders reported the poorest mental health and were most likely to seek care, the presence of a mental disorder, regardless of co-occurring substance dependence, contributed primarily to help seeking. Among those who sought services, the use of informal sources of care, including self-help groups, was more common among those with substance dependence. Those with co-occurring disorders reported the lowest satisfaction with care and the greatest prevalence of unmet need. CONCLUSIONS: The differential use of services, satisfaction, and unmet need across diagnostic status allowed for speculation on differing levels of disability and stigma in the help-seeking process for different types of disorders. The strong association between co-occurring disorders and unmet need for care, including a large proportion of respondents who stated they preferred to self-manage their symptoms, is particularly troubling and deserves future research attention.

Substance use and abuse in first-episode psychosis: prevalence before and after early intervention.

UNLABELLED: Despite the high prevalence of substance abuse among first-episode psychosis (FEP) populations, few studies examine whether early intervention (EI) improves substance abuse. OBJECTIVE: To examine the prevalence and pattern of substance use and abuse among an FEP sample over 12 months. METHODS: All the participants were diagnosed with a first episode of a schizophrenia spectrum disorder. The participants were followed prospectively. The prevalence rates of substance use and abuse from this sample were compared before and after 12 months of EI services and were compared with rates observed in a sample from the general population. RESULTS: A total of 200 participants (80.0% males; mean age 24 years) entered the study: 183 participants completed all the assessments at baseline, 131 participants completed all the assessments at 12 months. At baseline, the findings showed similar prevalence rates between the FEP sample and the general sample for lifetime cannabis use (60% vs 55%, respectively) and hazardous alcohol use (26% vs 21%) but significantly different prevalence rates for lifetime hallucinogen (29% vs 15%; P < .001) and cocaine use (20% vs 14%; P < .001). At 12 months, the prevalence rates for drug abuse (P < .01), hazardous alcohol use (P < .01), and concurrent drug abuse and hazardous alcohol use (P < .05) were significantly lower than at baseline. CONCLUSION: Substance use and abuse decreased significantly after 12 months of EI services; EI services may be able to detect and to reduce substance use among FEP patients before it becomes a more serious disorder.

Alcohol consumption, alcoholics anonymous membership, and homicide mortality rates in Ontario 1968 to 1991.

BACKGROUND: Research has shown a strong link between alcohol use and a variety of problems, including violence. Parker and colleagues have presented a selective disinhibition theory for the link between alcohol use and homicide (and other violence) that posits a causal relationship that is also influenced by other situational and contextual factors. This model is particularly well suited for aggregate-level investigations. In this study, we examine the impact of alcohol factors, including consumption measures and Alcoholics Anonymous (AA) membership rates, on homicide mortality rates in Ontario, and test predictions derived from the selective disinhibition model. METHODS: Time series analyses with ARIMA modeling were applied to total, male, and female homicide rates in Ontario between 1968 and 1991. The analyses performed included total alcohol consumption, spirits consumption, beer consumption, and wine consumption. Missing AA membership data were interpolated with cubic splines. RESULTS: For the total population and males, homicide rates were significantly and positively related to total alcohol consumption and to the consumption of beer and spirits. They were also negatively related to AA membership rates in the analyses involving spirits and wine and positively related to unemployment rates in the analyses involving beer, wine, and total alcohol. Among females, none of the measures were significant predictors of homicide mortality rates. CONCLUSIONS: These data provide important support for the selective disinhibition model and confirm important relationships between per capita consumption measures and homicide mortality rates, especially among males, seen in other studies. Additionally, the results for AA membership rates are consistent with the hypothesis that AA membership and treatment for misuse of alcohol can exert beneficial effects observable at the population level.

Alcohol consumption, alcoholics anonymous membership, and suicide mortality rates, Ontario, 1968-1991.

OBJECTIVE: The goal of this study is to identify alcohol-related factors that influence mortality rates from suicide. Specifically, we examine the impact of per capita consumption of total alcohol, distilled spirits, and beer and wine; unemployment rate; and Alcoholics Anonymous (AA) membership rate on total and male and female suicide mortality rates in Ontario between 1968 and 1991. METHOD: We studied the impact of alcohol consumption levels, AA membership rates, and unemployment rates on suicide mortality rates in Ontario from 1968 to 1991. Time series analyses with Auto Regressive Integrated Moving Average (ARIMA) modeling were applied to total and male and female suicide rates. The analyses performed included total alcohol consumption, distilled spirits consumption, beer consumption, and wine consumption. Missing AA membership data were interpolated with cubic splines. RESULTS: Total alcohol consumption and consumption of each of beer, distilled spirits, and wine were significantly and positively related to total and female suicide mortality rates. AA membership rates were negatively related to total and female suicide rates. Although data for males did not reach significance (except for the relationship between wine consumption and suicide rate), the direction of effects was consistent with that observed for female and total suicide rates. Unemployment rates were positively related to male and total suicide rates in some models. CONCLUSIONS: These data confirm the important relationships between per capita consumption measures and suicide mortality rates seen by previous investigators. Additionally, the results for AA membership rates are consistent with the hypothesis that AA membership and treatment for misuse of alcohol can exert beneficial effects observable at the population level.

Cirrhosis mortality in Ontario: effects of alcohol consumption and Alcoholics Anonymous participation.

AIMS: We test the hypotheses that cirrhosis mortality rates are positively associated with per capita alcohol consumption and negatively associated with Alcoholics Anonymous (AA) membership rates. DESIGN: The impact of alcohol consumption levels and AA membership rates on cirrhosis mortality rates in Ontario from 1968 to 1989 were examined. Time-series analyses with ARIMA modelling were applied to male and female cirrhosis mortality rates in three age groups: 15-44, 45-64 and 65 + years. Missing AA membership data were interpolated using two methods: linear splines and cubic splines. FINDINGS: In general, cirrhosis mortality rates were positively associated with alcohol consumption and negatively associated with AA membership. For some age and gender combinations, these effects were not statistically significant. CONCLUSIONS: The limits of this study include restrictions in the length of series available and in the ability to infer causality. Despite these limitations, these findings are consistent with previous research demonstrating that per capita consumption is a strong determinant of cirrhosis mortality rates, and also that higher levels of AA membership can reduce cirrhosis mortality rates.

Individuals seeking treatment for cannabis-related problems in Ontario: demographic and treatment profile.

We report on the extent of cannabis treatment-seeking within an addiction treatment system in Canada. Data represent all new admissions in fiscal year 2000 to substance abuse treatment agencies in the province of Ontario (n = 47,995). Analyses examine the prevalence of cannabis problems by demographic and treatment characteristics and provide contrasts with other client subgroups (alcohol, cocaine, and opiates). Clients reporting cannabis as their primary problem substance (13%) were more likely to be male, single, under age 20 and in high school. Legal system involvement and school- or family-based pressure to enter treatment were commonly reported, but less so by older cannabis clients. The distinctiveness of these clients within the larger treatment system raises questions of the relevance to cannabis clients of interventions designed for other substance-abusing populations.

Who seeks treatment for cannabis-related problems?

PURPOSE: To examine the types of presenting problems and symptoms among individuals seeking treatment for cannabis-related problems in a large treatment centre in Ontario. METHODS: Data from assessment interviews conducted with clients who identified cannabis as their primary drug problem (n=426) were analyzed using descriptive statistics. RESULTS: The majority of people seeking treatments were male (80%) and single (77%). Cannabis treatment seekers varied in their socio-demographic characteristics, drug consumption, pressure to seek treatment, and adverse consequences of cannabis use. They experienced a broad range of substance-related problems, however, the majority were classified as below the action stage in terms of readiness to change their drug consumption. Daily users were older, more likely to be employed, to be cannabis dependent, to suffer from an anxiety disorder, and to use multiple substances. DISCUSSION: Cannabis treatment seekers are a heterogeneous group. A better understanding of the relationship between client characteristics and different interventions may improve outcomes.

Substance abuse treatment and pressures from the criminal justice system: data from a provincial client monitoring system.

AIMS: Compulsory treatment is discussed increasingly as a way to reduce the population burden of addictive behaviours. This study explores the extent to which social control strategies exercised through the criminal justice system are used to bring people into substance abuse treatment at a system level. We also assessed whether particular subgroups may be more or less likely to be brought into treatment in this manner. DESIGN: We employed a secondary analysis of data from a client-based information system which captured demographic, referral and substance use characteristics from people seeking treatment for substance abuse. PARTICIPANTS: A census of clients (n = 45123) entering specialized Ontario addiction treatment programmes between 1 April 1999 and 31 March 2000. FINDINGS: Some 28.9% of clients reported legal problems at treatment intake, and 13.9% had an explicit corrections-related condition of treatment contact. Logistic regression analyses indicated that legal problems and corrections-related conditions of treatment were more prevalent among younger, unmarried and unemployed males, who had not completed high school. A number of important interactions were identified between these factors and substance of abuse. CONCLUSIONS: Implications for equity, accessibility and effectiveness of substance abuse treatment are discussed in relation to the tendency of treatment mandates from criminal justice system to disproportionately affect the entry of this segment of substance-abusing clients.

Physicians' enquiries into their patients' alcohol use: public views and recalled experiences.

AIMS: To examine public opinion and experiences of family physician involvement in alcohol use issues and to identify patient characteristics associated with these opinions and experiences. DESIGN: A secondary analysis of population survey data from the 1993 Ontario Alcohol and Other Drug Opinion Survey (OADOS), a random household telephone survey of adults in Ontario, Canada. Opinion and experiences regarding alcohol use were examined by drinking status. PARTICIPANTS: All survey respondents (n = 941; 65% response rate). Population expansion weights were applied to ensure the sample's representativeness of the adult population of Ontario. MEASUREMENTS: Measures assessed the prevalence of opinions and experiences of family physicians: (1) asking patients about their drinking; (2) advising regular drinkers to cut down/quit; and (3) helping patients with alcohol problems. Self-reported past-year alcohol consumption and related problems were used to construct a categorical variable describing current drinking status. FINDINGS: Public opinion supported routine inquiries into patients' drinking habits and advising regular drinkers to cut down. However, the experience of being asked by a physician about drinking, being advised to cut down or being helped with alcohol problems was uncommon. Respondents' drinking status was associated with experiences of being asked about drinking and being advised to cut down. CONCLUSIONS: Physician training should inform physicians that public opinion supports inquiries about drinking and advisement to reduce consumption, as it does not appear that family doctors are meeting these expectations of patients.
