Cannabis Consumers' View of Regulated Access to Recreational Cannabis: A Multisite Survey in Switzerland.

INTRODUCTION: There is considerable effort in legalizing recreational use of cannabis globally. The successful implementation of a program of regulated access to recreational cannabis (PRAC) depends on the consumers' engagement. The aim of this study was to examine the acceptability of twelve different regulatory aspects by cannabis users including those obtaining cannabis from the illicit market and vulnerable populations such as young adults and problematic users. METHODS: The current study is a multisite online survey conducted in Switzerland. A total of 3,132 adult Swiss residents who consumed cannabis within the previous 30 days represented the studied population. Mean age was 30.5 years, 80.5% were men, and 64.2% of the participants stated that they always or often obtain cannabis from the illicit market. We described consumers' acceptability of twelve regulatory aspects concerning THC content control, disclosure of sensitive personal data, security aspects, and follow-up procedures by applying descriptive statistics and multiple regression models. RESULTS: THC content regulation showed most discrepancy with 89.4% of the participants stating to engage in a PRAC if five different THC contents were available as compared to 54% if only 12% THC was available. The least accepted regulatory aspect was disposal of contact details with an acceptability rate of 18.1%. Consumers mainly obtaining cannabis from the illicit market, young adults, and problematic users showed similar acceptability patterns. Participants obtaining cannabis from the illicit market were more likely to engage in a PRAC if five different THC contents were available as compared to participants obtaining cannabis from other sources (OR 1.94, 95% CI: 1.53-2.46). CONCLUSION: A carefully designed PRAC that takes into account the consumers' perspective is likely to transfer them to the regulated market and to engage vulnerable populations. We cannot recommend the distribution of cannabis with only 12% THC content as this is unlikely to engage the target population.

Impaired glutamate homeostasis in the nucleus accumbens in human cocaine addiction.

Cocaine addiction is characterized by overwhelming craving for the substance, which drives its escalating use despite adverse consequences. Animal models suggest a disrupted glutamate homeostasis in the nucleus accumbens to underlie addiction-like behavior. After chronic administration of cocaine, rodents show decreased levels of accumbal glutamate, whereas drug-seeking reinstatement is associated with enhanced glutamatergic transmission. However, due to technical obstacles, the role of disturbed glutamate homeostasis for cocaine addiction in humans remains only partially understood, and accordingly, no approved pharmacotherapy exists. Here, we applied a tailored proton magnetic resonance spectroscopy protocol that allows glutamate quantification within the human nucleus accumbens. We found significantly reduced basal glutamate concentrations in the nucleus accumbens in cocaine-addicted (N = 26) compared with healthy individuals (N = 30), and increased glutamate levels during cue-induced craving in cocaine-addicted individuals compared with baseline. These glutamatergic alterations, however, could not be significantly modulated by a short-term challenge of N-acetylcysteine (2400 mg/day on 2 days). Taken together, our findings reveal a disturbed accumbal glutamate homeostasis as a key neurometabolic feature of cocaine addiction also in humans. Therefore, we suggest the glutamatergic system as a promising target for the development of novel pharmacotherapies, and in addition, as a potential biomarker for a personalized medicine approach in addiction.

'Placement budgets' for supported employment: impact on employment rates in a multicentre randomised controlled trial.

BACKGROUND: The most effective rehabilitation model for job (re-)entry of people with mental illness is supported employment. A barrier to introducing supported employment into standard care is its temporally unlimited provision, which conflicts with health and social legislation in many European countries. AIMS: To test the impact of different 'placement budgets', i.e. a predefined maximum time budget for job seeking until take-up of competitive employment. METHOD: Participants (116) were randomly assigned to 25 h, 40 h or 55 h placement budgets in an intent-to-treat analysis. We applied the individual placement and support model over 24 months, following participants for 36 months. Primary outcome was employment in the labour market for at least 3 months. RESULTS: The proportion of participants obtaining competitive employment was 55.1% in the 25 h group, 37.8% in the 40 h group and 35.8% in the 55 h group. In a Cox regression analysis, time to employment was slightly lower in the 25 h group relative to the 40 h (hazard ratio 1.78, 95% CI 0.88-3.57, P = 0.107) and 55 h groups (hazard ratio 1.74, 95% CI 0.86-3.49, P = 0.122), but this was not statistically significant. The vast majority of all participants who found a job did so within the first 12 months (80.4%). CONCLUSION: A restricted time budget for job finding and placement does not affect the rate of successful employment. In accordance with legislation, a restriction of care provision seems justified and enhances the chances of supported employment being introduced in statutory services.

Predictors of Employment for People With Mental Illness: Results of a Multicenter Randomized Trial on the Effectiveness of Placement Budgets for Supported Employment.

Background: Individual placement and support (IPS) has proven to be effective for vocational outcomes in people with mental illness. The original concept of IPS requires temporally unlimited provision of support. Using limited placement budgets and investigating factors that predict their effectiveness may inform decisions about resource allocation. Methods: A range of patient characteristics were tested as predictors of employment outcomes in participants who attended six outpatient psychiatric clinics in Switzerland between June 2010 and May 2011. Overall, 116 patients with the full spectrum of psychiatric conditions were randomly assigned and started an IPS intervention, which was provided by three different placement budgets. Support lasted 2 years for those who found a job, and outcomes were repeatedly assessed over 3 years. The intervention ended for those who failed to find competitive employment by the time their placement budget had run out. Results: Of the 15 variables tested, only Global Assessment of Functioning (GAF) and Clinical Global Impression (CGI) scores were predictors for obtaining work (for ≥1 day) and for maintaining it over a longer period (>3 months). Higher GAF and lower CGI scores increased the odds of obtaining employment and keeping it for at least 3 months. Functional role impairment, quality of life, self-esteem, or education level did not predict employment. Conclusion: Our data suggest that, if time-restricted budgets are offered to a wide range of patients, such as those included in this study, better functioning and lower symptom severity at baseline are predictive of better employment outcomes (finding and maintaining work) on the first (competitive) labor market in Switzerland. It remains to be investigated whether this holds true under different environmental factors. Clinical Trial Registration: ISRCTN, trial number: ISRCTN89670872.

Cannabis use in Switzerland 2015-2045: A population survey based model.

BACKGROUND: Alternative cannabis regulation models are discussed and implemented worldwide. A baseline scenario under the assumption of no policy or market changes may prove useful to forecast cannabis use and treatment demand and evaluate changes in legislation. METHODS: Based on data of the Continuous Rolling Survey of Addictive Behaviours and Related Risks on cannabis use, age, gender and nationality from 2011 to 2015, we used general estimating equation analysis to model lifetime and 30-days prevalence from 2015 to 2045 in Switzerland accounting for demographic trends. RESULTS: Lifetime prevalence of cannabis use is projected to grow from 28.3% (CI 95% 27.8-28.8) in 2015 to 42.0% (CI 95% 41.0-43.0) in 2045. 30-days prevalence would increase slightly from 2.70% (CI 95% 2.53-2.88) to 3.39% (CI 95% 3.11-3.66). Due to population growth, absolute numbers with past 30-day cannabis use are estimated to increase from 202,784 (CI 95% 189,534-216,035) to 314,302 (CI 95% 288,504-340,100). Among those aged under 30 years no substantial change in lifetime and 30-days prevalence of cannabis use is projected. Larger changes are estimated to occur in the age group 30+. The mean age of past 30-day cannabis users would increase for men with Swiss nationality from 30.3 to 38.7 years. DISCUSSION: Population-based survey data and demographic projections can be used to develop baseline scenarios of future cannabis use. Assuming no changes in cannabis legislation, growing absolute numbers of users will likely increase treatment demand. Cannabis use is estimated to increase among the group aged >30 years, which is currently underrepresented in clinical treatment and research. Our findings highlight the need for prospective baseline scenarios to evaluate the impact of legislative changes on cannabis use. Moreover, in Switzerland effective prevention and treatment interventions for cannabis use disorders are required even if cannabis legislation remains unchanged.

One size does not fit all-evolution of opioid agonist treatments in a naturalistic setting over 23 years.

BACKGROUND AND AIMS: Opioid agonist treatment (OAT) is currently the most effective treatment for people with opioid dependence. In most countries, however, access to the whole range of effective medications is restricted. This study aims to model the distribution of different OAT medications within a naturalistic and relatively unrestricted treatment setting (Zurich, Switzerland) over time, and to identify patient characteristics associated with each medication. METHODS: We used generalized estimating equation analysis with data from the OAT register of Zurich and the Swiss register for heroin-assisted treatment (HAT) to model and forecast the annual proportion of opioids applying exponential distributions until 2018 and patient characteristics between 1992 and 2015. RESULTS: Data from 11 895 patients were included in the analysis. Methadone remains the mainstay of OAT, being prescribed to two-thirds of patients. Following its approval, the proportion of HAT increased rapidly and is now constant at 12.16% [95% confidence interval (CI) = 11.15-13.17]. The initial increase of proportions of buprenorphine or slow-release oral morphine (SROM) following their approval for OAT was slower. While in 2014 both medications had a proportion of 10.2% and 10.3%, respectively, our model predicts a further increase of SROM to 19.9% in 2018, with a ceiling level of 25.19% (21.40-28.98%) thereafter. SROM patients display characteristics similar to those treated with methadone; buprenorphine patients show the highest social integration; and HAT patients are the most homogeneous group, with highest mean age, most widespread injecting experience and lowest social integration. CONCLUSIONS: Based on data from Zurich, Switzerland from 1992 to 2015, there is no evidence for an excessive demand for a single medication in a naturalistic and liberal opioid agonist treatment setting. Rather, the specific patient characteristics associated with each medication underline the need for diversified treatment options for opioid dependence.

"Placement Budgets" for Supported Employment-Impact on Quality of Life in a Multicenter Randomized Controlled Trial.

Background: Employment is an important aspect of psychiatric rehabilitation. The objective of this analysis was to explore how quality of life (QoL) may affect the outcome of supported employment and vice versa. Methods: A total of 116 participants with severe mental disorders were randomly assigned to either 25, 40, or 55 h placement budgets, which comprises job coaches' time resources to support a client in finding a job. The intervention followed the individual placement and support model and lasted up to 36 months. Primary outcome was employment in the first labor market for at least 3 months. QoL was assessed 7 times over the entire 36-months observation period using the WHO QoL Bref, which comprises the dimensions physical health, psychological, social relationships, and environment. Results: The three placement budgets did not differentially relate to QoL, but QoL environment showed a significant increase over time across all three groups. Baseline QoL environment weakly predicted subsequent obtainment of employment (F = 4.08, df = 1, p = 0.046, Cohen's d = 0.39). Controlling for baseline QoL, those participants who obtained a job, as compared to those who did not, showed persistent increases in QoL physical health (b = 0.39, p = 0.002, Cohen's d = 0.50) and QoL psychological (b = 0.40, p < 0.001, Cohen's d = 0.47). Conclusion: Obtaining employment in the first labor market improves patients' QoL. Supported employment is a valuable intervention that may benefit patients with severe mental disorder.

Long-Term Opioid Agonist Treatment Participation after First Treatment Entry is Similar across 4 European Regions but Lower in Non-Nationals.

Heroin users in opioid agonist treatment (OAT) show markedly reduced heroin consumption, less crime and a lower mortality rate. However, the extent of long-term OAT participation over subsequent treatment episodes remains unclear. We analysed the annual proportion of patients in treatment (at least 1 day) since the start of first OAT in 4 European regions: Barcelona (BA) 1996-2012: 8,602 patients; Czech -Republic (CZ) 2000-2014: 4,377 patients; Netherlands (NL) 1994-2014: 33,235 patients, Zurich (ZU) 1992-2015: 11,795. We estimated the long-term decline of treatment need due to mortality or abstinence and also a "nuisance" short-term decline until the equilibrium level of cycling in and out of OAT is reached to obtain the adjusted treatment participation value. The adjusted treatment participation was around 50% (BA: 47.4-51.4%; CZ: 49.8-53.9%; NL: 52.3-54.0%; ZU: 46.4-49.3%), and the annual decline of treatment need was close to 4%. Non-nationals (NL patients with a migrant background) showed substantial lower adjusted treatment participation (rate ratio BA: 0.059-0.343; NL: 0.710-0.751; ZU: 0.681-0.797; CZ: n.a.). Our method may provide a policy-relevant indicator of long-term provision, quality and access to OAT following first treatment.

Predictors of repeat visits to hospital psychiatric emergency departments in Malaga (Spain) and in Lisbon (Portugal).

OBJECTIVE: This study describes the profile of people with mental disorders attending emergency departments (EDs) in two countries and to identify specific mental disorders associated with repeat emergency visits. METHODS: Retrospective analyses of 1 year of EDs data from two hospitals with psychiatric departments, one in Amadora/Sintra (Lisbon, Portugal, 2008) and the other in Malaga (Spain, 2009), were carried out. To determine which mental disorders were associated with repeat visits in each setting, negative binomial models were calculated. RESULTS: There were 5141 visits for a mental disorder made by 3667 patients. Patients with affective disorder were the most frequent (32.2%). Among all mental health patients, 19.9% had at least one repeat visit during the year. For the two EDs setting combined, patients with personality disorders (incidence rate ratio (IRR)=3.79, 95% CI: 2.39 to 6.02) and psychotic disorders (IRR=1.46, 95% CI: 1.13 to 1.89) were more likely to have repeat visits compared with patients with affective disorders, whereas mental disorders due to psychoactive substance use (IRR=0.52, 95% CI: 0.37 to 0.73) was associated with lower likelihood of repeat visits. Nearly all significant differences were attributable to the Malaga sample, where patients with personality disorders were four times more likely to have repeat EDs visits compared with patients with affective disorders. However, at both sites, patients with mental disorders due to psychoactive substance use were less likely to have repeat visits. CONCLUSIONS: Certain mental disorders may be predictive of more frequent ED visits. The different results for each country suggest that further studies might focus not only on the characteristics of patients, but also on local healthcare organisation.

Telecommunications Network Measurements of Online Gambling Behavior in Switzerland: A Feasibility Study.

BACKGROUND: Methodological shortcomings of gambling studies relying on self-report or on data sets derived from gambling operators tend to result in biased conclusions. The aim of this study was to analyze online gambling behavior using a novel network database approach. METHODS: From October 13 to October 26, 2014, telecommunications network data from a major telecommunications provider in Switzerland were analyzed. Netflows between mobile devices and a poker operator were quantified to measure the gambling duration and session number. RESULTS: Time spent gambling during night and working hours was compared between devices with longest (red group), intermediate (orange group), and shortest gambling time (green group). Online gambling behavior differed depending on overall gambling time, F (2, 3,143). Night and working hours gambling was the highest in the red group (53%), compared to the orange (50.1%) and the green groups (41.5%). Post hoc analyses indicated significant differences between the orange and green groups (p < 0.05). No differences were observed between the red and orange groups (p = 0.850), and the red and green groups (p = 0.053). CONCLUSIONS: On mobile devices, distinct gambling patterns were observed depending on the overall gambling time. This methodology could also be used to investigate online gaming, social media use, and online pornography.

Changes in substance use in patients receiving opioid substitution therapy and resulting clinical challenges: a 17-year treatment case register analysis.

BACKGROUND: Although the beneficial effects of opioid substitution for the reduction of heroin use are well established, its effect on other substance use is unclear. We aimed to evaluate short-term and long-term changes in substance use in opioid-dependent patients on opioid substitution therapy. We focused on frequent use of heroin, cocaine, benzodiazepines, and alcohol under naturalistic conditions (ie, with non-selected patients and clinical practice as usual) over 17 years. METHODS: This was a treatment case register analysis. Data were obtained from the treatment case register of the canton of Zurich, Switzerland, which included information for 8962 patients (122 399 case report forms) who received substitution therapy with methadone or buprenorphine between 1998 and 2014. The main focus of our study was to evaluate long-term changes in frequent substance use of patients on opioid substitution therapy, together with the associations between individual, treatment, and environmental factors and substance use, including short-term changes at first treatment entry. Data were analysed using a generalised estimating equation that accounted for individual, treatment, and environmental factors. Frequent use was defined as substance use on at least 5 days per week. FINDINGS: The most frequent use of heroin (odds ratio [OR] 5·30, 95% CI 4·63-6·08; p<0·0001), cocaine (2·30, 1·95-2·71; p<0·0001) and, to a lesser extent, benzodiazepines (1·34, 1·17-1·54; p<0·0001) and alcohol (1·21, 1·08-1·35; p=0·0007), was found in previously untreated individuals compared with patients already receiving treatment 6 months after starting opioid substitution therapy, corroborating a strong effect of initiating substitution therapy. Frequency of substance use was associated with the year of evaluation: frequent use of heroin (OR per decade 0·56, 0·52-0·60; p<0·0001) and cocaine (0·63, 0·58-0·68; p<0·0001) significantly decreased between 1998 and 2014, while frequent alcohol use increased (1·15, 1·08-1·23; p<0·0001). In 2014, frequent alcohol use was observed in 990 (22·5%) of 4400 patients on opioid substitution therapy. INTERPRETATION: Frequent use of alcohol during opioid substitution therapy significantly increased during the observation period, whereas there was a decline in frequent use of heroin and cocaine. Given the high infection rates with hepatotoxic viruses and the increasing liver-related mortality rates in patients on opioid substitution therapy, these findings suggest that frequent alcohol use increasingly constitutes a therapeutic challenge in opioid substitution therapy. FUNDING: None.

[Acute day hospital as a cost-effective alternative to inpatient therapy]. / Akut-Tagesklinik als kosteneffiziente Alternative zu stationärer Therapie.

BACKGROUND: This is a study of the cost-benefit advantage of the model project acute day hospital (ATK) compared to inpatient care. METHODS: The study was performed retrospectively and examined the direct costs and the Global Assessment of Functioning (GAF) in a matched sample. RESULTS: The day clinic treatment compared to inpatient therapy showed at a cost benefit of 2.68: 1 at a slightly delayed increase in GAF-value. CONCLUSION: The treatment in ATK is more than twice as cheap compared to inpatient treatment, but at a slightly slower improvement in symptoms.

Rethinking retention in treatment of opioid dependence-The eye of the beholder.

Opioid dependence often is a chronic relapsing disorder. The evidence for medication-assisted treatment (MAT) being the treatment of first choice is unequivocal. Yet, health systems, professionals and patients often fail to offer or, respectively, to enter long-term and low-threshold MAT and instead treat opioid dependence as a semi-acute disorder. We claim that the typical perspective on treatment retention, one of the pivotal outcomes used for evaluation of MAT, contributes to this phenomenon by obscuring the chronic nature of opioid dependence. To support this hypothesis, we use data of 11,819 patients obtained from the MAT register of the canton of Zurich 1991-2015 and illustrate three different perspectives on treatment retention: the prospective "trial" perspective looking at the duration of single treatment episodes; the retrospective "provider" perspective looking at the duration of treatment episodes of patients still in treatment; and the "public health" perspective looking at the proportion of days spent in treatment regardless of single treatment episodes. Integrating these perspectives will lead to a more realistic perception of the chronic nature of opioid dependence. This will allow determining more appropriate aims and time frames for MAT in practice and research.

Neurocognition in help-seeking individuals at risk for psychosis: Prediction of outcome after 24 months.

An important aim in schizophrenia research is to optimize the prediction of psychosis and to improve strategies for early intervention. The objectives of this study were to explore neurocognitive performance in individuals at risk for psychosis and to optimize predictions through a combination of neurocognitive and psychopathological variables. Information on clinical outcomes after 24 months was available from 118 subjects who had completed an extensive assessment at baseline. Subjects who had converted to psychosis were compared with subjects who had not. Multivariate Cox regression analyses were used to determine which baseline measure best predicted a conversion to psychosis. The premorbid IQ and the neurocognitive domains of processing speed, learning/memory, working memory and verbal fluency significantly discriminated between converters and non-converters. When entered into multivariate regression analyses, the combination of PANSS positive/negative symptom severity and IQ best predicted the clinical outcomes. Our results confirm previous evidence suggesting moderate premorbid cognitive deficits in individuals developing full-blown psychosis. Overall, clinical symptoms appeared to be a more sensitive predictor than cognitive performance. Nevertheless, the two might serve as complementary predictors when assessing the risk for psychosis.

Association of Supported Employment With Cognitive Functioning and Employment Outcomes.

OBJECTIVE: Cognitive functioning affects employment outcomes in supported employment. This study examined which cognitive parameters are associated with employment outcomes for persons with mental illnesses and discusses possible mechanisms involved. METHODS: Data stem from a randomized controlled trial conducted as part of the Zürich Impulse Program for the Sustainable Development of Mental Health Services (ZInEP). A sample of 116 patients in supported employment was recruited, coached, and followed up. Factor analysis and logistic regression were used to determine cognitive parameters associated with employment outcomes. RESULTS: Results showed that verbal learning was positively associated with better employment outcomes (any job and employment for at least three months). CONCLUSIONS: Results of this study imply that training in verbal learning should be included in supported employment programs. More generally, elaborated models are needed to explain interactions between cognitive functioning, supported employment, and employment outcomes and to enhance understanding of the interrelationships between cognitive functioning, employment outcomes, and any mediating and moderating variables.

Evaluation of medication-assisted treatment of opioid dependence-The physicians' perspective.

BACKGROUND: There is controversy about which outcome parameters should be employed to assess substance use treatment. Subjective measures of medication-assisted treatment (MAT) of opioid dependence are increasingly important. However, while patients' perspectives have been examined, the caregivers' views remain largely unknown. Here, we explore how physicians evaluate MAT, and which predictors are most relevant. METHODS: We conducted a retrospective cohort study of all MAT episodes with oral opioid agonists in the canton of Zurich between 1998 and 2013 using a case register. Termination forms of the register include a physician-completed assessment on the course of the treatment episode. Mixed model analysis was applied to determine relevant predictors. RESULTS: The analysis was based on 17,234 episodes from 7432 patients. Mean global assessment of the course of MAT was 'moderate'. The most important predictors for treatment evaluation by physicians were treatment break off as reason for termination (p<0.0001), psychological improvement throughout treatment (p<0.0001), wish for abstinence from the substitute (p<0.0001), social integration index at termination (p<0.0001), and social (p<0.0001) as well as medical (p<0.0001) improvement. The negative association of treatment break off with MAT assessment was more pronounced in semi-rural than urban areas (p<0.0001). CONCLUSION: Predictors relating to the well-being and functioning of the patient as well as the reasons underlying treatment termination appear to be more important for the treating physician's evaluation of medication-assisted treatment episodes than on-going substance use. Coming off the opioid medication plays a central role, independent of ongoing illicit substance use.

Age- and gender-specific mortality risk profiles for depressive outpatients with major chronic medical diseases.

BACKGROUND: As leading causes of death, chronic medical diseases, particularly common cardiovascular diseases, are associated with depression. The combination of depression and chronic medical disease in turn is linked with poorer health and premature death. Despite numerous studies on mortality in people with depression and chronic medical disease, the effects of age and gender were not consistently considered. To appropriately estimate mortality in the clinical setting, we aimed to analyse age- and gender-specific mortality profiles in outpatients with depression and chronic medical disease by considering depression severity. METHODS: We examined data from N=327,018 outpatients with depression aged 18 years and older (mean=60 years), which we obtained from German electronic health-insurance claims data covering the years 2007-2010. We considered major chronic medical disease groups: cardiovascular diseases, diabetes, diseases of the respiratory system and cancer. To analyse both adjusted mortality risk and rates over one year in a comprehensive manner, we calculated General Estimation Equation (GEE) Poisson models for binary data. RESULTS: The mortality risk increased with age and was higher for males. Especially patients below 60 years of age with cancer or diabetes had an increased mortality risk, but not patients with cardiovascular disease. Mortality was comparably increased in patients with severe depression, diabetes or respiratory disease. LIMITATIONS: We did not have data from a control group without depression. CONCLUSIONS: Notably, not cardiovascular diseases but cancer and, to a lesser extent, diabetes, both in younger patients, respiratory diseases and severity of depression require particular attention in outpatient care to reduce mortality.

Supported Employment for the Reintegration of Disability Pensioners with Mental Illnesses: A Randomized Controlled Trial.

Work is beneficial for the recovery from mental illness. Although the approach of individual placement and support (IPS) has been shown to be effective in Europe, it has not yet been widely implemented in European health care systems. The aim of this randomized controlled trial was to assess the effectiveness of IPS for disability pensioners with mental illnesses new on disability benefits in Switzerland. In the study at hand, 250 participants were randomly assigned to either the control or the intervention group. The participants in the intervention group received job coaching according to IPS during 2 years. The control group received no structured support. Both groups were interviewed at baseline and followed up every 6 months (baseline, 6, 12, 16, 18, 24 months) for 2 years. Primary outcome was to obtain a job in the competitive employment. IPS was more effective for the reintegration into the competitive employment market for disability pensioners than the control condition. Thirty-two percent of the participants of the intervention group and 12% of the control group obtained new jobs in the competitive employment. IPS is also effective for the reintegration into competitive employment of people with mental illness receiving disability pensions.
