A Review of Substance Use Disorder Treatment in Developing World Communities

Prevalence of Mental Disorders in Abakaliki, Ebonyi State, Southeastern Nigeria

BACKGROUND

Increasing psychological stressors have posed challenges to the well-being of the people across the globe and greatly affected the functionality and economic output of the individuals and the society. Nigeria has no existing mental health registry. Data on the prevalence of mental disorders are not readily available owing to lack of mental health registry. Hence, this study assessed the prevalence of mental disorders in Abakaliki metropolis, Ebonyi State.

AIM

To determine the prevalence of mental disorders and associated factors among the residents of Abakaliki metropolis, Ebonyi State.

METHOD

This cross-sectional descriptive research study involved 400 participants. Questionnaires adapted from world mental health diagnostic interview and General Health Questionnaire 12 were used for data collection. Data were analyzed using descriptive statistics and hypotheses tested using chi-square test at significance level of .05.

RESULTS

The prevalence of mental disorders among the respondents was 70% depressive disorders and 52.3% substance use disorders-tranquilizers (34.9%) and stimulants (15.8%) were the commonly used, while 85.3% suffered anxiety disorders. These were common among age range of 19 to 28 years-those with higher education and the unemployed. More females had mental disorders except substance use disorders, which was higher in males (53.4%). There was no significant relationship between mental disorders and the demographic variables, but significant relationship was found to exist between individuals' age and anxiety disorder.

CONCLUSION

Mental disorders, such as depression, anxiety, and substance use disorders, are common among the respondents and, therefore, calls for urgent attention of the government to improve the mental health of the people.

Treating alcohol use disorder in the absence of specialized services - evaluation of the moving inpatient Treatment Camp approach in Uganda

BACKGROUND

The gap between service need and service provision for alcohol-related disorders is highest in resource-poor countries. However, in some of these contexts, local initiatives have developed pragmatic interventions that can be carried out with limited specialized personnel. In an uncontrolled treatment study, we aimed to evaluate the feasibility, acceptability, safety, costs and potential effects of an innovative locally developed community-based program (the Treatment Camp) that is based on an inpatient clinic that moves from community to community.

METHODS

Out of 32 treatment-seeking individuals 25 took part in the one-week Treatment Camp that included detoxification and counseling components. Re-assessments took place 5 and 12 months after their participation. We explored the course of a wide range of alcohol-related indicators, using the Alcohol Use Disorders Identification Test (AUDIT) as primary outcome complemented by a timeline follow-back approach and the Obsessive Compulsive Drinking Scale. Additionally, we assessed impaired functioning, alcohol-related stigmatization, symptoms of common mental health disorders and indicators of family functioning as reported by participants' wives and children.

RESULTS

All alcohol-related measures decreased significantly after the Treatment Camp and remained stable up to the 12-month-assessment with high effect sizes ranging from 0.89 to 3.49 (Hedges's g). Although 92% of the participants had lapsed at least once during the follow-up period, 67% classified below the usually applied AUDIT cutoff for hazardous drinking (≥ 8) and no one qualified for the dependent range (≥ 20) one year after treatment. Most secondary outcomes including impaired functioning, alcohol-related stigmatization, symptoms of depression and indicators of family functioning followed the same trajectory.

CONCLUSIONS

We found the Treatment Camp approach to be acceptable, feasible, safe and affordable (approx. 111 USD/patient) and we could obtain preliminary evidence of its efficacy. Due to its creative combination of inpatient treatment and monitoring by medical personnel with local mobility, the Treatment Camp appears to be more accessible and inclusive than other promising interventions for alcohol dependent individuals in resource-poor contexts. Effects of the approach seem to extend to interactions within families, including a reduction of dysfunctional and violent interactions.

Targets for intervention to prevent substance use in young people exposed to childhood adversity: A systematic review

Background and aims

Childhood adversity is a strong, and concerningly prevalent, risk factor for the later development of substance misuse. Yet despite substantial accumulating evidence for causal mechanisms, there has been little attempt to synthesize the strength of the evidence. Importantly, these mechanisms may be amenable to intervention, providing targets for substance use prevention among those exposed to childhood adversity. The present review aimed to systematically identify mediating and moderating mechanisms operating between childhood adversity and substance use.

Methods

A systematic review was conducted. Electronic databases (PubMed, MEDLINE, PsycINFO, Web of Science and CINAHL) were searched from 1998 to 2020 for modifiable mediators and moderators of the relationship between childhood adversity and substance use in people aged 10–24. Data was qualitatively synthesised, using a socio-ecological perspective to group mediators/moderators into individual, interpersonal, community, and public policy/cultural levels of behaviour.

Results

After screening against eligibility criteria, 50 studies were included in the current review. The mediators at the individual level of behaviour showing the largest and most consistent effect sizes included externalising behaviour, anger, coping motives for substance use, and post-traumatic stress symptoms. Among individual-level moderators, religiosity, future orientation and depressive symptoms all attenuated the relationship between childhood adversity and substance use. At the interpersonal level, peer relationships and mother-child relationships mediated the effect of adversity on substance use. Moderators included family cohesion and relationship quality. Community factors were less commonly studied, though school mobility and educational achievement mediated 14% and 28% of the total effect of childhood adversity on substance use respectively. No mediators or moderators were identified for public policy/culture.

Conclusions

A substantial proportion of the relationship between childhood adversity and substance use in youth is mediated through individual, interpersonal and community factors. Coupled with the knowledge that existing, evidence-based programs effectively address many of the identified mediators and moderators, this review advances knowledge on optimal targets to prevent substance misuse among those exposed to childhood adversity.

Peer-delivered services for substance use in low- and middle-income countries: A systematic review

BACKGROUND AND AIMS

Addressing the burden of disease associated with substance use is a global priority, yet access to treatment is limited, particularly in low- and middle-income countries (LMICs). Peers, individuals with lived experience of substance use, may play an important role in expanding access to treatment, supporting outcomes, and reducing stigma. While peer-delivered services for substance use have been scaling up in high-income countries (HICs), less is known about their application in LMICs. This systematic review synthesizes the evidence of peer-delivered services for substance use in LMICs.

METHODS

PsycINFO, Embase, Global Health, PubMed, and six region-specific databases were searched, and articles that described peer-delivered services for substance use and related outcomes in LMICs were included. Risk of bias was evaluated using tools appropriate for each study design. To provide a more stringent evaluation of structured interventions, a subset of articles was analyzed using the Cochrane Effective Practice and Organization of Care (EPOC) framework.

RESULTS

The search yielded 6540 articles. These were narrowed down to 34 included articles. Articles spanned four continents, included quantitative and qualitative methodologies, and primarily targeted infectious disease risk behaviors. Ten articles were included in the EPOC sub-analysis. In the context of high risk of bias, some of these articles demonstrated positive impacts of the peer-delivered services, including reductions in risk behaviors and increases in infectious disease knowledge scores, while many others showed no significant difference in outcomes between peer intervention and control groups.

CONCLUSIONS

Peer-delivered services may be feasible for addressing substance use and reducing infectious disease risk behaviors in LMICs, where there are severe human resource shortages. Globally, peers' lived experience is valuable for engaging patients in substance use treatment and harm reduction services. Further research is needed to better characterize and quantify outcomes for peer-delivered services for substance use in LMICs.

Quality of life among people who use drugs living in poor urban communities in the Philippines

BACKGROUND

The quality of life (QOL) and mental health of people who use drugs (PWUD) in the Philippines, especially those living in poor urban communities, are highly concerning due to the situations surrounding drug use and the ongoing hard-line antidrug policy. This study aimed to investigate the QOL and mental health status of PWUD, compare them with a comparison group with no history of drug use, and identify factors associated with QOL among Filipino PWUD.

METHODS

A cross-sectional study was conducted with recruitment from a community-based rehabilitation programme and poor urban communities in Muntinlupa in 2018. QOL was measured using the WHOQOL-BREF, while psychological distress and posttraumatic stress disorder (PTSD) were measured using the Kessler Psychological Distress Scale (K-6) and the Primary Care PTSD Screen for DSM-5 (PC-PTSD-5), respectively. Multivariable linear regressions with each WHOQOL-BREF domain as a dependent factor were conducted to establish three predictions: age- and gender-adjusted QOL means, factors associated with QOL among PWUD, and interaction of lifetime drug use with each covariate.

RESULTS

In total, 272 PWUD and 402 comparison participants were recruited. Most PWUD were current drug users (53%), primarily of methamphetamine (70%). Among PWUD, the prevalence of moderate to severe psychological distress was 70%, and probable PTSD was 28%-both rates higher than those among the comparison group. All four QOL domain scores (physical, psychological, social, and environmental) of PWUD were lower than those of the comparison group. Multivariable regressions showed that psychological distress, current drug use, selling drugs, experiencing discrimination, and being never-married were associated with lower QOL. Higher individual income, household resources, social activity participation, and service use for drug use problems were associated with higher QOL among PWUD. Stratified and interaction analyses revealed that the QOL of PWUD was more sensitive to changes in individual income relative to the QOL of comparison group.

CONCLUSION

A comprehensive intervention addressing psychological distress reduction, economic empowerment, and social inclusion-complementary to abstinence-oriented programmes-may improve the well-being of Filipino PWUD.

Effectiveness of Psychosocial Interventions Targeting Hazardous and Harmful Alcohol Use and Alcohol-Related Symptoms in Low- and Middle-Income Countries: A Systematic Review

BACKGROUND

In low- and middle-income countries (LMIC), the mismatch between the number of individuals needing and those receiving treatment for alcohol use disorders (AUD) is substantial. In order to provide suggestions for the scaling up of effective service provision we systematically reviewed the current evidence on the effectiveness of AUD-focused psychosocial interventions in LMIC.

METHODS

We used a systematic review methodology following the PRISMA guidelines. Twelve electronic databases listing published and grey literature were searched and only randomized-controlled trials (RCTs) were included. Where possible, effect sizes were calculated using Hedges' g indices.

RESULTS

Twenty-one RCTs conducted in 15 different LMIC between 1992 and 2018 fulfilled inclusion criteria. Most studies employed brief one-on-one interventions facilitated by trained primary care staff. Eighty-six percent of RCTs based their interventions on the principles of motivational interviewing (MI) with the majority supplementing MI-based interventions with alcohol-tailored elements of cognitive-behavioral therapy (CBT). The remaining RCTs employed CBT-components exclusively. Just over 40% of studies included in quantitative analyses (n=17) yielded an at least medium-sized effect (g≥.50) of the respective intervention compared to alcohol-related and unrelated control conditions or waiting list. Only half of the trials implementing the widely applied MI-based approaches (or MI-based approaches blended with CBT-elements) were superior to their respective control conditions.

CONCLUSION

To date, a relatively small number of RCTs investigating AUD-focused treatments has been conducted in LMIC. The majority of between condition effect size estimates were small and no type of intervention can clearly be recommended over another. No RCTs were conducted in conflict-affected areas in LMIC although they would merit particular attention since AUD is often linked to trauma-related mental health disorders. More RCTs in LMIC are required and alternatives to MI-based approaches should be investigated. This systematic review summarizes properties of effective interventions and provides implications for future research.

A review of the public sector substance use disorder treatment and prevention systems in Kenya

Background

The burden of substance use disorders in sub-Saharan Africa has been projected to increase by an estimated 130% by 2050. Despite this, little is known about the substance use disorder treatment and prevention systems in the region.

Objectives

The objective of this review is to describe the public sector substance use disorder treatment and prevention systems in Kenya guided by the World Health Organization health systems framework model, with the aim of informing decision-making.

Methods

We reviewed official government documents obtained from hand-searching the websites of relevant governmental organizations including: Ministry of Health, National Authority for the Campaign Against Alcohol and Drug Abuse, Parliament of Kenya, Ministry of Treasury & National Planning, National Law Reporting Council, Kenya National Bureau of Statistics, the National Non-Governmental Organization (NGO) Coordination Board and the 47 County Governments. We augmented those searches with official documents that the authors were aware of by virtue of being practitioners in the field. Draft and retired documents were excluded. The findings of the search are presented as a narrative review.

Discussion

The Mental Health Act 1989, the main legislative framework governing substance use disorder treatment and prevention, focuses on institutional care only. While there are only three public health facilities offering substance use disorder treatment in Kenya, several non-public sector actors are involved in SUD treatment and prevention activities. Unfortunately, there is limited cross-sector collaboration. The Ministry of Health has no specific budget for substance use disorder treatment and prevention, while the National Authority for the Campaign Against Alcohol and Drug Abuse has an annual resource gap of about US$ 5,000,000. The substance use disorder workforce in Kenya has not been characterized.

Conclusion

We propose five key strategies for strengthening substance use disorder treatment and prevention systems in Kenya including: (1) Enactment of the Mental Health (Amendment) bill 2018. (2) Integration of substance use disorder treatment and prevention into primary health care to increase access to care. (3) Utilization of money from taxation of alcohol, tobacco and betting to increase funding for substance use disorder treatment and prevention. (4) Characterization of the substance use disorder workforce to inform planning. (5) Enhanced collaboration between the government and non-state actors in order to increase access to SUD treatment and prevention.

Problematic alcohol use among fathers in Kenya: Poverty, people, and practices as barriers and facilitators to help acceptance

BACKGROUND

In Kenya, the prevalence of alcohol use disorder (AUD) is close to 6%, but a notable treatment gap persists. AUD is especially pronounced among men, leading to negative consequences at both individual and family levels. This study examines the experiences of problem-drinking fathers in Kenya regarding previous treatment-seeking related to alcohol use. Experiences and dynamics of the family are also explored as they pertain to treatment-seeking experiences.

METHODS

In Eldoret, Kenya, semi-structured qualitative interviews were conducted with 11 families with a male exhibiting problem drinking, his spouse, and one child. Thematic content analysis was used to examine themes related to barriers and facilitators to treatment.

RESULTS

Participants only reported informal help received from family and community members; they exhibited little awareness of available formal treatments. Families were both deeply affected by alcohol use and actively involved in help-seeking. Indeed, fathers' experiences are described as help-accepting rather than help-seeking. Three overarching themes emerged from the results: poverty, people, and practices. Poverty could be a motivator to accept help to support one's family financially, but stress from lack of work also drove drinking behaviours. People were also crucial as both barriers and facilitators of help-accepting. Negative help strategies or peer influence deterred fathers from accepting help to quit. Positive motivation, social support, and stigma against drinking were motivators. Practices that were culturally salient, such as religiosity and gender roles, facilitated help acceptance. Overall, most help efforts were short-term and only lead to very short-term behaviour change.

CONCLUSION

Families and communities are active in help provision for problem-drinking men in Kenya, though results confirm remaining need for effective interventions. Future interventions could benefit from recognizing the role of family to aid in treatment-engagement and attending to the importance of poverty, people, and practices in designing treatment strategies.

Cross-national patterns of substance use disorder treatment and associations with mental disorder comorbidity in the WHO World Mental Health Surveys

AIMS

To examine cross-national patterns of 12-month substance use disorder (SUD) treatment and minimally adequate treatment (MAT), and associations with mental disorder comorbidity.

DESIGN

Cross-sectional, representative household surveys.

SETTING

Twenty-seven surveys from 25 countries of the WHO World Mental Health Survey Initiative.

PARTICIPANTS

A total of 2446 people with past-year DSM-IV SUD diagnoses (alcohol or illicit drug abuse and dependence).

MEASUREMENTS

Outcomes were SUD treatment, defined as having either received professional treatment or attended a self-help group for substance-related problems in the past 12 months, and MAT, defined as having either four or more SUD treatment visits to a health-care professional, six or more visits to a non-health-care professional or being in ongoing treatment at the time of interview. Covariates were mental disorder comorbidity and several socio-economic characteristics. Pooled estimates reflect country sample sizes rather than population sizes.

FINDINGS

Of respondents with past-year SUD, 11.0% [standard error (SE) = 0.8] received past 12-month SUD treatment. SUD treatment was more common among people with comorbid mental disorders than with pure SUDs (18.1%, SE = 1.6 versus 6.8%, SE = 0.7), as was MAT (84.0%, SE = 2.5 versus 68.3%, SE = 3.8) and treatment by health-care professionals (88.9%, SE = 1.9 versus 78.8%, SE = 3.0) among treated SUD cases. Adjusting for socio-economic characteristics, mental disorder comorbidity doubled the odds of SUD treatment [odds ratio (OR) = 2.34; 95% confidence interval (CI) = 1.71-3.20], MAT among SUD cases (OR = 2.75; 95% CI = 1.90-3.97) and MAT among treated cases (OR = 2.48; 95% CI = 1.23-5.02). Patterns were similar within country income groups, although the proportions receiving SUD treatment and MAT were higher in high- than low-/middle-income countries.

CONCLUSIONS

Few people with past-year substance use disorders receive adequate 12-month substance use disorder treatment, even when comorbid with a mental disorder. This is largely due to the low proportion of people receiving any substance use disorder treatment, as the proportion of patients whose treatment is at least minimally adequate is high.

Change in psychosocial factors connected to coping after inpatient treatment for substance use disorder: a systematic review

BACKGROUND

Among the adult population worldwide, about 0.5% has illicit drug use disorder (DUD) and about 5% has alcohol use disorder (AUD). Dependency on alcohol, medication or illicit drugs are recognised as risk factors for disabling disease and early death. Treatment for substance use disorders (SUD) is important in promoting persistent abstinence and may be perceived as a valuable public health measure. The current systematic review aims at exploring how psychosocial factors connected to recovery capital and coping behaviour, change after inpatient SUD treatment.

METHODS

A systematic search was conducted in Campbell Collaboration Library, Cochrane Library, EMBASE, Epistemonikos, Medline, PsychINFO, Social Sciences Citation Index and SocINDEX. Cohort studies on psychosocial outcomes for adults who had attended to inpatient SUD treatment that exceeds 3 months, were included. The outcome of interest was change in psychosocial factors. The search results were identified as include, exclude or unclear by one author and then screened by the second author with a specific focus on studies recognised as unclear. Diverging evaluations of eligibility among the unclear studies were resolved by discussion. In case of disagreement, the third author decided the eligibility of the studies in question.

RESULTS

Findings imply an overall progress in mental health, and a potential improvement in employment status and perceived social support after inpatient SUD treatment. Additionally, findings indicate a decrease in substance use from admission to follow-up after discharge from inpatient SUD treatment. These findings are consistent with earlier research on important factors in recovering from SUD. Findings on change in self-efficacy, housing, education and Quality of Life (QoL) however, were scantly researched and were expected to be more prominent outcomes of interest among the included studies.

CONCLUSION

Due to the substantial resources used to provide SUD treatment, knowledge about recovery capital, like psychosocial factors that facilitate coping behaviour and reintegration to society, should be standardised and used by SUD treatment providers.

A study of pathways to care among opioid dependent individuals seeking treatment at a community de-addiction clinic in India

Drug use, including opioid use disorder, is one of the rapidly rising and serious problems affecting populations globally. There is a treatment gap and delay in presentation of drug users to treatment centers. The present study aimed at assessing the pathways to care among opioid-dependent individuals seeking treatment from a community-based treatment center in India. In a cross-sectional observational study conducted at a community clinic of the National Drug Dependence Treatment Centre (NDDTC), New Delhi, India, a total of 100 treatment-seeking drug users (age 18-60 years) fulfilling DSM IV TR criteria for opioid dependence were recruited. The data were collected using a semistructured pro forma based on patient self-report and the encounter form used in the World Health Organization (WHO) Pathway Study. All participants were male, were mostly married, were employed, and belonged to nuclear families. Ninety-eight percent of participants has ever used heroin in a dependent fashion and 20% were using it currently. Mean age of the participants was 40.83 years (SD 12.7). Median age of onset of heroin use was 22 years (IQR 12). Median duration of heroin use was 138 months (IQR 132). Only 21% of participants visited the community deaddiction clinic at the first contact with care. The median time for first treatment-seeking attempt was 9.5 years (IQR 7). The study findings suggest significant delay between onset of drug-related problems and first treatment contact. There is a need to increase the availability and accessibility of treatment services to reduce the delay in treatment seeking.

Mental health knowledge, attitudes, and self-efficacy among primary care physicians working in the Greater Tunis area of Tunisia

BACKGROUND

Non-specialists' involvement in mental health care is encouraged in the field of global mental health to address the treatment gap caused by mental illness, especially in low- and middle-income countries. While primary care physicians (PCPs) are involved in mental health care in Tunisia, a lower-middle-income country in North Africa, it is unclear to what extent they are prepared and willing to address mental health problems, substance use disorders, and suicide/self-harm. In this context, we aim (1) to report on mental health knowledge, attitudes, and self-efficacy among a sample of PCPs working in the Greater Tunis area, prior to the implementation of a mental health training program developed by the World Health Organization; and (2) to identify what characteristics are associated with these competencies.

METHODS

In total, 112 PCPs completed questionnaires related to their socio-demographic and practice characteristics, as well as their mental health knowledge, attitudes, and self-efficacy. Descriptive analyses and regression models were performed.

FINDINGS

PCPs had more knowledge about depression, symptoms related to psychosis, and best practices after a suicide attempt; had favourable attitudes about distinctions between physical and mental health, learning about mental health, and the acceptance of colleagues with mental health issues; and believed most in their capabilities related to depression and anxiety. However, most PCPs had less knowledge about substance use disorders and myths about suicide attempts; had unfavorable attitudes about the dangerousness of people with mental health problems, personal disclosure of mental illness, non-specialists' role in assessing mental health problems, and personal recovery; and believed the least in their capabilities related to substance use disorders, suicide/self-harm, and psychosis. Participation in previous mental health training, weekly hours (and weekly hours dedicated to mental health), weekly provision of psychoeducation, and certain work locations were associated with better mental health competencies, whereas mental health knowledge was negatively associated with weekly referrals to specialized services.

CONCLUSIONS

Findings suggest that PCPs in our sample engage in mental health care, but with some gaps in competencies. Mental health training and increased interactions/involvement with people consulting for mental health issues may help further develop non-specialists' mental health competencies, and integrate mental health into primary care settings.

Cytological Findings of Malignant and Benign Head and Neck Masses in Somalia

OBJECTIVE

There are no up-to-date records on head and neck masses (HNMs) in Somalia. This cytological study is the first to demonstrate the benefits and findings of fine-needle aspiration cytology in evaluating HNMs in the adult population of Somalia.

STUDY DESIGN

A total of 116 aspiration samples were taken from different levels of the neck region, except for the thyroid. Cases were classified as salivary gland, lymph node, or soft tissue/cystic lesions. They were classified according to age, gender, and cytological diagnosis.

RESULTS

Patients included 54 (46.6%) males and 62 (53.4%) females, with a mean age of 40.6 years. Seventy-two patients (62.1%) had benign lesions, while 44 (37.9%) had malignant lesions. Necrotizing granulomatous lymphadenitis (n = 51, 70.8% of the benign findings) and lymph node metastasis of squamous cell carcinoma (n = 13, 29.5% of the malignant findings) were the most frequent findings.

CONCLUSION

Fine-needle aspiration is a useful procedure in the diagnosis of neck masses. It is a cheap and easy guiding method for diagnosing granulomatous lymphadenitis and advanced-stage metastatic cancers, which are common in this country.

The effect of a behavioral activation treatment for substance use on post-treatment abstinence: a randomized controlled trial

AIMS

To compare outcomes for a behavioral activation group treatment for substance use [life enhancement treatment for substance use (LETS ACT)] versus a time and group size-matched control condition delivered in a residential treatment setting.

DESIGN

Single-site two-arm parallel-group randomized clinical trial with follow-up assessment at 3, 6 and 12 months post-treatment.

SETTING

Residential substance use treatment facility in the United States.

PARTICIPANTS

Participants were 263 adults [mean age 42.7 (11.8); 29.5% female; 95.4% African American; 73.2% court mandated] whose insurance dictated 30-day (65.9%) or 90-day (34.1%) treatment duration.

INTERVENTION AND COMPARATOR

LETS ACT (n = 142) is a treatment developed originally for depression and modified for substance use. It teaches participants to increase positively reinforcing value-driven activities in order to counter depression and relapse. The control group [supportive counseling (SC); n = 121] received time and group size-matched supportive counseling. Treatment was delivered in five or eight 1-hour sessions depending on patient length of stay.

MEASUREMENTS

Percentage abstinent at follow-up, percentage of substance use days among those reporting use, depressive symptoms [Beck Depression Inventory (BDI)] and adverse consequences of drug use [Short Inventory of Problems-Alcohol and Drug (SIP-AD)].

FINDINGS

LETS ACT had significantly higher abstinence rates at 3 months [odds ratio (OR) = 2.2, 95% confidence interval (CI) = 1.3-3.7], 6 months (OR = 2.6, 95% CI= 1.3-5.0) and 12 months (OR = 2.9, 95% CI = 1.3-6.1) post-treatment compared with SC. LETS ACT participants reported significantly fewer adverse consequences from substance use at 12 months post-treatment [B = 4.50, standard error (SE) = 2.17, 95% CI = 0.22-8.78]. Treatment condition had no effect on percentage substance use days among those who resumed use or on change in depressive symptoms; the latter decreased over time only in those who remained abstinent after residential treatment irrespective of condition (B = 0.43, SE = 0.11, 95% confidence interval = 0.22-0.65).

CONCLUSIONS

A behavioral activation group treatment for substance use (LETS ACT) appears to increase the likelihood of abstinence and reduce adverse consequences from substance use up to 12 months post-treatment.
