Predictors of retention in the 'voluntary' and 'quasi-compulsory' treatment of substance dependence in europe

Relapse in involuntary substance treatment: a transversal study

OBJECTIVE

To evaluate the associations between relapse and admissions (voluntary and involuntary) in a sample of patients with substance dependence.

METHODS

This is a cross-sectional study undertaken at a private medical therapeutic community specialised in treating addiction, located in a rural area of São Paulo, Brazil. Sociodemographic characteristics, the University of Rhode Island Change Assessment Scale (URICA), Stages Readiness and Treatment Eagerness Scale (SOCRATES), Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) and Structured Clinical Interview for DSM-IV-SCID were used.

RESULTS

Relapse was associated with low family income (P=.006) and contemplation motivational stage (P<0.05). Nevertheless, no significant differences between individuals who were admitted involuntarily (64%) and voluntarily (54%) were observed (P=0.683) in terms of relapses.

CONCLUSIONS

In this sample, the relapse outcome in involuntary admissions was no different from the voluntary ones.

Treatment Attendance Among Veterans With Depression, Substance Use Disorder, and Trauma

OBJECTIVE

Low attendance in psychotherapy, particularly among individuals with comorbid disorders, is a pervasive challenge. The present study examined predictors of treatment attendance in a sample of veterans with depression, substance use disorder, and trauma.

METHODS

This is an analysis of data collected as part of a larger clinical trial involving outpatients at a Veterans Administration dual diagnosis clinic. Individuals were excluded if they had significant memory deficits, schizophrenia, bipolar disorder, or substantial travel constraints. Participants (N = 146) received 12 weeks of group-delivered integrated cognitive behavioral therapy for depression and substance use, followed by randomization to 12 additional weeks of individually delivered cognitive behavioral therapy (n = 62) or cognitive processing therapy (n = 61) modified to address substance use and trauma. Participants, therapists, and researchers were not blinded to group assignment. For this study, we included only the 123 participants who were randomized into the second phase, analyzing predictors of treatment attendance categorized into predisposing factors, enabling factors, and need factors.

RESULTS

Participants were primarily male (89%) and Caucasian (76%) and averaged 47 years old (SD = 12). Forty-four percent had alcohol use disorder, 16% had drug use disorder, and 40% had polysubstance use disorder. Most met criteria for PTSD (82%), with 44% having combat-related trauma, 33% sexual trauma, and 28% other trauma. Treatment attendance did not differ between groups. More education was associated with increased group (r = .19, p = .04) and individual session attendance (r = .28, p = .002). Individuals with chronic housing problems attended fewer group sessions (r = -.19, p = .04), while individuals with sexual trauma, compared to those with other traumas, attended more individual sessions (r = .23, p = .01). Number of group sessions attended was positively associated with individual session attendance.

CONCLUSIONS

Few variables were significantly predictive of treatment attendance, possibly due to the complex nature of comorbid disorders. Including a focus on trauma was not associated with lower attendance. Special consideration may need to be given to education level, homelessness, and trauma when trying to engage and retain patients with comorbid disorders in treatment. This clinical trial is registered at www.clinicaltrials.gov as NCT00958217.

Predictors of dropout from psychosocial treatment in opioid-dependent outpatients

BACKGROUND AND OBJECTIVES

Early dropout is common in substance abuse treatment settings and may lead to poorer outcomes relative to those completing a full course of treatment. Attempts to identify predictors of dropout have yielded mixed results, highlighting the need for additional research in this area to clarify risk and protective factors to guide intervention and retention efforts. This study evaluated predictors of dropout from psychosocial treatment among opioid-dependent patients on methadone maintenance therapy.

METHODS

Participants included 78 patients who had failed to respond to at least 4 months of methadone maintenance plus group counseling with clinic substance abuse counselors, and were enrolled in a study of randomized psychosocial treatment in addition to treatment-as-usual. Several factors that have been implicated in previous studies as well as two affective variables (distress intolerance and coping motives for drug use) were examined.

RESULTS

Results indicated that when controlling for various risk factors, age was the only significant predictor of dropout, with younger patients more likely to discontinue treatment early.

CONCLUSIONS

This study replicates previous findings in opioid-dependent samples that younger patients are at an increased risk of early treatment dropout.

CONCLUSIONS AND SIGNIFICANCE

Targeted intervention may be needed to retain young patients in drug abuse treatment.

Health-related and legal interventions: A comparison of allegedly delinquent and convicted opioid addicts in Austria

In Austria, judges can offer quasi-compulsory treatment options (in- and outpatient settings) as an alternative to imprisonment for drug-related delinquencies. A standard assessment of medical, psychological and legal data on the implementation of health-related and legal interventions in Austria was applied in 96 opioid-dependent individuals (10.4% female) undergoing quasi-compulsory treatment, receiving health-related measures. Additional data from the official prison registry were collected (data of 228 imprisoned individuals sentenced for drug-related crimes; 14.5% female) to gain comparable information to in- and outpatient health-related measure groups. Health-related measures were offered significantly more often to individuals charged with solely narcotics possession and/or trade, whereas imprisonment was filed significantly more often when concomitant property or violent crimes were committed in addition to drug possession/dealing (p < 0.001). Both cohorts had high prevalences of previous convictions (health-related measure 84.4%, prison 93.9%). The majority of patients in health-related measures suffered at the time of investigation from severe depression (62.5%), anxiety disorders (58.3%) and had a high loading of suicidal ideation (45.8%). Women showed a higher prevalence of affective disorders (p = 0.042), with higher administration rates of psychopharmacological medication (p = 0.045), whereas male offenders scored significantly higher in violent behaviour (p = 0.004). Inpatients showed a significantly higher burden of comorbid disorders compared to outpatients and reported a higher need for psychiatric treatment and legal counselling (all p < 0.001). The inpatient sample had a longer duration of opioid use (p = 0.024), a higher lifetime prevalence of intravenous drug use (p < 0.001) and a higher rate of hepatitis C infections (p = 0.012). Results confirm that imprisonment is sentenced to a vast extent for severe crimes, and health-related measure is well accepted among judges. However, based on patients’ high loading of previous convictions and alarmingly high burden of comorbidities, quality improvement and assurance in health-related measure are required when patients have their first contact with the criminal justice system. Continuous focus on applying diversion procedures is also required to reduce societal costs.
