Housing and supportive services for young mothers experiencing substance use disorder and homelessness: Cost-effectiveness analysis of a randomized trial

BackgroundMothers experiencing homelessness and caring for young children struggle with high rates of substance use and mental health problems. A comprehensive supportive housing intervention was implemented to assist young mothers experiencing substance use disorder (SUD) and homelessness. The cost-effectiveness of this intensive intervention could inform future dissemination. MethodsA cost-effectiveness analysis was conducted alongside a randomized controlled trial that lasted from May 2015 to October 2018. Mothers experiencing homelessness between the ages of 18–24 years with a SUD were randomly assigned to housing+support services (HOU + SS) (n = 80), housing-only (HOU) (n = 80), or services as usual SAU (n = 80). Using incremental cost-effectiveness ratios (ICERs), the study compared the costs of HOU + SS and HOU to SAU for three outcomes: housing stability (percent days of stable housing), substance use (percent days of substance use), and depressive symptoms (Beck Depression Inventory score). Direct intervention costs of HOU + SS and HOU from both payor and societal perspectives were estimated. Cost data were collected from detailed study financial records. Outcomes were taken from 6-month assessments. ResultsThe average societal cost of HOU + SS per participant was $5114 [CI 95 %, $4949-5278], while the average societal cost of HOU was $3248 [CI 95 %, $ 3,140–$3341] (2019 U.S. dollars). The calculated ICERs show that HOU was more cost-effective than HOU + SS and SAU for housing outcome. For illicit drug use, HOU + SS was more cost-effective than HOU. Finally, for depressive symptoms, neither HOU + SS or HOU were more cost effective than SAU. ConclusionWhile HOU is more cost-effective for increasing housing, HOU + SS is more cost-effective for reducing illicit drug use. However, housing without improvements in substance use may not be sustainable, and supportive services are likely essential for improved well-being overall beyond the housing outcome alone.

Does smoking cessation reduce other substance use, psychiatric symptoms, and pain symptoms? Results from an emulated hypothetical randomized trial of US veterans.

Quitting smoking may lead to improvement in substance use, psychiatric symptoms, and pain, especially among high-risk populations who are more likely to experience comorbid conditions. However, causal inferences regarding smoking cessation and its subsequent benefits have been limited. We emulated a hypothetical open-label randomized control trial of smoking cessation using longitudinal observational data of HIV-positive and HIV-negative US veterans from 2003-2015 in the Veterans Aging Cohort Study. We followed individuals from the first time they self-reported current cigarette smoking (baseline). We categorized participants as quitters or non-quitters at the first follow-up visit (approximately 1 year after baseline). Using inverse probability weighting to adjust for confounding and selection bias, we estimated odds ratios for improvement of co-occurring conditions (unhealthy alcohol use, cannabis use, illicit opioid use, cocaine use, depressive symptoms, anxiety symptoms, and pain symptoms) at second follow-up (approximately 2 years after baseline) for those who quit smoking compared to those who did not, among individuals who had the condition at baseline. Of 4,165 eligible individuals (i.e., current smokers at baseline), 419 reported no current smoking and 2,330 reported current smoking at the first follow-up. Adjusted odds ratios (95% confidence intervals) for associations between quitting smoking and improvement of each condition at second follow-up were: 2.10 (1.01, 4.35) for unhealthy alcohol use, 1.75 (1.00, 3.06) for cannabis use, 1.10 (0.58, 2.08) for illicit opioid use, and 2.25 (1.20, 4.24) for cocaine use, 0.78 (0.44, 1.38) for depressive symptoms, 0.93 (0.58, 1.49) for anxiety symptoms, and 1.31 (0.84, 2.06) for pain symptoms. While a causal interpretation of our findings may not be warranted, we found evidence for decreased substance use among veterans who quit cigarette smoking but none for the resolution of psychiatric conditions or pain symptoms. Findings suggest the need for additional resources combined with smoking cessation to reduce psychiatric and pain symptoms for high-risk populations.

A realist review of residential treatment for adults with substance use disorder.

Completion of residential treatment for substance use disorder (SUD) relates to improvements in substance use and mental health. Findings from systematic reviews have been equivocal about which interventions work best for clients. There has been limited attention to the theories that explain the effectiveness of residential treatment. We conducted a realist review of the literature to identify program theories that would explain successful and unsuccessful outcomes from residential treatment for SUD. The unit of analysis was context-mechanism-outcome (CMO). Inclusion criteria were studies of residential treatment of more than 30 days for adults with SUD. Pharmacological studies were excluded. We identified 24 studies from 5748 screened. The studies were from settings comprising Indigenous programs, faith-based programs, psycho-social interventions and therapeutic communities and were conducted in North America, Scandinavia, Continental Europe and Australasia. We chose six CMO configurations as the best explanations for outcomes from residential treatment. Theories that best explained the mechanisms of change were the need to belong, meaning in life, and self-determination theory. Previous research has noted similar outcomes from different residential treatment interventions, but has not been able to explain these similarities. In contrast, our findings suggest that the outcomes can be explained by causal mechanisms that apply across all programs, regardless of the philosophy of treatment. We identified six CMO configurations whose mechanisms of change could be explained by three overarching theories-the need to belong, meaning in life and self-determination theory. The findings apply across ethnicities and genders.

Housing and supportive services for substance use and self-efficacy among young mothers experiencing homelessness: A randomized controlled trial

AimsHomeless mothers with young children in their care contend with high rates of substance use and low self-efficacy. However, a limited number of studies have examined these outcomes associated with housing and supportive services. DesignParticipants were randomly assigned to: (1) housing + support services (n = 80), (2) housing-only (n = 80), or (3) services as usual (SAU) (n = 80) and were re-assessed at 3-, 6-, 9- and 12-months postbaseline. SettingsThe study recruited a community-based sample from homeless service agencies and advertisements in a large Midwestern city. ParticipantsThe study recruited two hundred forty (N = 240) women between the ages of 18 to 24 years, experiencing homelessness and with a substance use disorder (SUD) who also had a biological child under the age of 6 years in their care. MeasurementsWe measured frequency of alcohol and drug use using the Form 90 semi-structured interview, and self-efficacy using Pearlin and Schooler's (1978) 7-item Mastery Scale. FindingsOverall, mothers showed significant improvement in substance use and self-efficacy over time in each condition. However, as expected, patterns of change differentiated intervention groups with more mothers showing better substance use and self-efficacy outcomes in housing + supportive services than in SAU. Unexpectedly, more mothers in SAU showed better outcomes than those in housing-only. ConclusionsSubstance use decreased and self-efficacy increased over time, but patterns of change characterized the intervention groups. In particular, findings suggest that when providing housing to this population, supportive services should also be offered.

Alcohol Treatment Research Contributing to Changes in Substance Use Behavior and Related Negative Consequences

The purpose of this study was to investigate the extent to which two of the more salient characteristics of a treatment research assessment protocol (i.e., the comprehensiveness of the assessment battery and the frequency of its administration) for alcohol use disorder contribute to reductions in substance use and related negative consequences. Study participants were recruited from two hospital-administered substance use disorder outpatient clinics. Two hundred thirty-five individuals presenting for outpatient alcohol treatment screened study eligible and provided informed consent. Study participants were randomized to one of four research assessment conditions (i.e., frequent-comprehensive, frequent-brief, infrequent-comprehensive, and infrequent-brief) based on the crossing of a 2 (i.e., assessment comprehensiveness: comprehensive vs. brief) by 2 (i.e., assessment frequency: frequent vs. infrequent) factorial design. Individuals assigned to the frequent assessment conditions reported greater reductions in substance use and substance use-related negative consequences relative to their counterparts assigned to the infrequent assessment conditions. In addition, a greater proportion of individuals assigned to the frequent assessment conditions reported abstinence from both alcohol and other substances. The improvements in substance use and related negative consequences associated with more frequent research assessments were statistically significant and clinically meaningful.

The phenotype of recovery VII: Delay discounting mediates the relationship between time in recovery and recovery progress

IntroductionSubstance use disorders (SUDs) remain challenging maladies to treat in the United States and impose significant societal costs. Despite these challenges, a significant number of individuals endorse being in recovery from SUD. The scientific understanding of SUD recovery has evolved to include not only improvements in substance use but also improvements in personal wellness and psychosocial functioning. The devaluation of future rewards (delay discounting; DD) is broadly associated with SUD inception and outcomes. We sought to investigate the relationship between DD, time in recovery, and recovery progress. MethodsWe conducted an online assessment of 127 individuals in recovery from SUD who the study recruited via the International Quit and Recovery Registry (IQRR). The research team obtained measures of recovery progress via the Addiction Recovery Questionnaire (ARQ) and the Treatment Effectiveness Assessment (TEA). Additionally, the study collected measures of DD, time in recovery, and endorsement of abstinence in recovery (i.e., requiring abstinence vs. not). We utilized linear regression to test for associations among these variables and performed a mediation analysis to test the role of DD in mediating the relationship between time in recovery and measures of recovery progress. ResultsTime in recovery was positively associated with the ARQ (p < .001) and TEA (p < .001). Furthermore, an individual's delay discounting rate mediated the relationship between time in recovery and ARQ/TEA. Of the participants, 66% endorsed recovery requiring total abstinence from alcohol and drugs. Last, through an exhaustive model selection, the study did not find an individual's endorsement of abstinence in recovery to be a primary predictor of recovery progress. ConclusionsThis study presents evidence that, for individuals in recovery, the temporal view (i.e., focus on immediate vs. future rewards) is a significant influence on recovery progress. Additionally, an individual's endorsement of abstinence in recovery was not significantly associated with recovery progress, suggesting the importance of a holistic view of SUD recovery. These findings contribute to the understanding of recovery as a multidimensional process and provide further support for DD as a behavioral marker of addiction.

How might the \u2018Icelandic model\u2019 for preventing substance use among young people be developed and adapted for use in Scotland? Utilising the consolidated framework for implementation research in a qualitative exploratory study

BackgroundSubstance use among young people is a significant public health concern, particularly in Scotland. Primary prevention activities are essential in delaying young people’s substance use and reducing the harms associated with use. However, such prevention activities are generally lacking. The Icelandic Model (IM) has received increasing attention and has been associated with improvements in substance use in Iceland since the 1990s. There is interest in implementing the IM in Scotland but concerns regarding transferability. This research study aimed to address a gap in the evidence base by providing insight into stakeholders’ views of the IM in Dundee and more widely in Scotland.MethodsQualitative data were collected via semi-structured telephone interviews with 16 stakeholders. Data were analysed using Framework Analysis in NVivo, informed by the Consolidated Framework for Implementation Research.ResultsParticipants were keen for more prevention activities to be delivered in Scotland and were generally supportive of the IM, given the high rates of substance use and related harm. A range of positive factors were identified, including the evidence base, the multi-component nature of the IM, and availability of current services that could be embedded into delivery. Several barriers were noted, relating to funding, the franchise model, support and buy-in and cultural differences.ConclusionsOur findings provide insight into the views of a range of stakeholders regarding the potential implementation of the IM in Scotland, and perceived barriers and facilitators. There is a desire for primary prevention activities in Scotland, driven by concerns about high rates of substance use and related harms, and a general lack of effective and evidence based prevention activities across the country. Several key barriers would need to be addressed in order for implementation to be successful, and participants were clear that initial piloting is required. Future research and evaluation is required to examine its potential and the outcomes of the approach in Scotland.

Dissemination of cognitive behavioral therapy for substance use disorders in the Department of Veterans Affairs Health Care System: Description and evaluation of Veteran outcomes

Background As part of the nation’s largest dissemination and implementation of evidence-based psychotherapies (EBPs) and the promotion of EBPs for substance use disorders (SUDs), the Veterans Health Administration (VHA) is working to nationally implement Cognitive Behavioral Therapy for SUD (CBT-SUD). The current manuscript describes the approach to system-wide training and reports Veteran outcomes associated with CBT-SUD implementation. Methods: Four-hundred fifty-eight Veterans with a range of treatment goals received treatment through the Department of Veterans Affairs (VA) CBT-SUD Training Program. Veteran outcomes related to substance use, substance use-related problems, and quality of life were assessed with the Brief Addiction Monitor, the Short Inventory of Problems, and the World Health Organization Quality of Life-BREF. Results: Statistically significant reductions in alcohol use, heavy alcohol use, other drug use, and substance use-related problems, as well as significant improvements in quality of life, were observed over the course of treatment. Conclusions: Program evaluation findings suggest that large-scale training in and implementation of EBPs for SUDs is associated with improvements in substance use and other functional outcomes. Limitations from this real-world implementation project, including the lack of a control group and missing post-treatment data, are discussed.

A Therapeutic Relational Agent for Reducing Problematic Substance Use (Woebot): Development and Usability Study.

BackgroundMisuse of substances is common, can be serious and costly to society, and often goes untreated due to barriers to accessing care. Woebot is a mental health digital solution informed by cognitive behavioral therapy and built upon an artificial intelligence–driven platform to deliver tailored content to users. In a previous 2-week randomized controlled trial, Woebot alleviated depressive symptoms.ObjectiveThis study aims to adapt Woebot for the treatment of substance use disorders (W-SUDs) and examine its feasibility, acceptability, and preliminary efficacy.MethodsAmerican adults (aged 18-65 years) who screened positive for substance misuse without major health contraindications were recruited from online sources and flyers and enrolled between March 27 and May 6, 2020. In a single-group pre/postdesign, all participants received W-SUDs for 8 weeks. W-SUDs provided mood, craving, and pain tracking and modules (psychoeducational lessons and psychotherapeutic tools) using elements of dialectical behavior therapy and motivational interviewing. Paired samples t tests and McNemar nonparametric tests were used to examine within-subject changes from pre- to posttreatment on measures of substance use, confidence, cravings, mood, and pain.ResultsThe sample (N=101) had a mean age of 36.8 years (SD 10.0), and 75.2% (76/101) of the participants were female, 78.2% (79/101) were non-Hispanic White, and 72.3% (73/101) were employed. Participants’ W-SUDs use averaged 15.7 (SD 14.2) days, 12.1 (SD 8.3) modules, and 600.7 (SD 556.5) sent messages. About 94% (562/598) of all completed psychoeducational lessons were rated positively. From treatment start to end, in-app craving ratings were reduced by half (87/101, 86.1% reporting cravings in the app; odds ratio 0.48, 95% CI 0.32-0.73). Posttreatment assessment completion was 50.5% (51/101), with better retention among those who initially screened higher on substance misuse. From pre- to posttreatment, confidence to resist urges to use substances significantly increased (mean score change +16.9, SD 21.4; P<.001), whereas past month substance use occasions (mean change −9.3, SD 14.1; P<.001) and scores on the Alcohol Use Disorders Identification Test-Concise (mean change −1.3, SD 2.6; P<.001), 10-item Drug Abuse Screening Test (mean change −1.2, SD 2.0; P<.001), Patient Health Questionnaire-8 item (mean change 2.1, SD 5.2; P=.005), Generalized Anxiety Disorder-7 (mean change −2.3, SD 4.7; P=.001), and cravings scale (68.6% vs 47.1% moderate to extreme; P=.01) significantly decreased. Most participants would recommend W-SUDs to a friend (39/51, 76%) and reported receiving the service they desired (41/51, 80%). Fewer felt W-SUDs met most or all of their needs (22/51, 43%).ConclusionsW-SUDs was feasible to deliver, engaging, and acceptable and was associated with significant improvements in substance use, confidence, cravings, depression, and anxiety. Study attrition was high. Future research will evaluate W-SUDs in a randomized controlled trial with a more diverse sample and with the use of greater study retention strategies.Trial RegistrationClinicalTrials.gov NCT04096001; http://clinicaltrials.gov/ct2/show/NCT04096001.

Changes in clinical and social situation after involuntary admission of homeless people with psychotic disorders: a one-year follow-up study

Background Mental illness is one of the main reasons for homelessness in Denmark. Yet, some patients do not accept psychiatric treatment despite need for treatment. This can lead to involuntary admission. In this study, we examined changes after involuntary admissions of mentally ill homeless people. Methods We conducted a longitudinal, naturalistic follow-up study of patients who had been involuntarily admitted by the Homeless Outreach Psychiatric Service through 1 year. We examined changes in mental condition, social situation, and substance use of mentally ill homeless people one year after involuntary admission. Results At baseline, 28 patients were included: 86% of them had been admitted before, 46% had a substance use, and 25% had prior been convicted of a violent crime. 89% of the patients were discharged to the streets. At 12 months, 50% of the patients had symptom reduction, 36% were in psychiatric treatment, and only 14% had acquired permanent housing. No improvements in substance use were observed and 11% of the patients had new convictions after 12 months. During the study period, a total of 24 readmissions distributed on 14 patients was found. Conclusion Involuntary admissions can be an effective treatment of psychiatric aspects of mentally ill homeless patients. Unfortunately, a substantial part of these patients was quickly discharged before sufficient treatment, leaving room for improvement. Furthermore, few improvements were seen concerning the patients’ social situation. More focus on the coherence between psychiatric and municipality services, targeting the social issues and substance use of homeless patients, is strongly needed.

Longitudinal Substance Use and Biopsychosocial Outcomes Following Therapeutic Community Treatment for Substance Dependence.

The Therapeutic Community (TC) model is considered an effective treatment for substance dependence, particularly for individuals with complex presentations. While a popular approach for this cohort across a number of countries, few studies have focussed on biopsychosocial and longer-term outcomes for this treatment modality. This study reports on substance use, dependence, and biopsychosocial outcomes up to 9 months post-exit from two TC sites. Methods: A longitudinal cohort study (n = 166) with two follow-up time points. Measures included substance use, dependence, subjective well-being, social functioning, and mental and physical health. Generalized Linear Models were employed to assess change over time. Results: At 9 months, 68% of participants reported complete 90-day drug abstinence. Alcohol frequency and quantity were reduced by over 50% at 9 months, with 32% of the sample recording 90-day abstinence at 9 months. Both alcohol and drug dependence scores were reduced by over 60%, and small to medium effect sizes were found for a range of psychosocial outcomes at 9 months follow-up, including a doubling of wellbeing scores, and a halving of psychiatric severity scores. Residents who remained in the TC for at least 9 months reported substantially better outcomes. Conclusions: With notably high study follow-up rates (over 90% at 9 months post-exit), these data demonstrate the value of the TC model in achieving substantial and sustained improvements in substance use and psychosocial outcomes for a cohort with severe substance dependence and complex presentations. Implications for optimal length of stay are discussed.

Decreased drinking in adults with co-occurring cannabis and alcohol use disorders in a treatment trial for marijuana dependence: Evidence of a secondary benefit?

The purpose of the present study was to investigate whether cannabis dependent users who met criteria for a secondary diagnosis of alcohol use disorder (AUD) would increase their use of alcohol in response to decreasing their use of marijuana in a behavioral treatment trial for cannabis use disorder (CUD). This phenomenon is commonly known as “substance substitution.” Participants were randomly assigned to one of four 9-session treatment conditions with cannabis and alcohol use measured at baseline, posttreatment, and at 4 follow-ups through 14 months. Of those enrolled (n = 198), 27 (13.6%) also met criteria for AUD. Linear mixed models were used to analyze alcohol use over time with cannabis use and time as predictors. Findings demonstrated that there were no associations between declines in cannabis use and changes in alcohol consumption in the full sample. However, among those with CUD who also had AUD, declines in cannabis use significantly predicted concurrent declines in alcohol use (p < .05). This study did not find evidence of substance substitution among individuals receiving treatment for CUD. Contrary to expectations, the results indicated that individuals with AUD were more likely to decrease, rather than increase, their alcohol use when they reduced their marijuana use. Treatment for CUD in this study appeared to result in improvements in substance use generally, at least for those with comorbid AUD.

Veterans with PTSD and comorbid substance use disorders: Does single versus poly-substance use disorder affect treatment outcomes?

IntroductionSubstance use disorders (SUD) frequently co-occur with posttraumatic stress disorder (PTSD). Little is known, however, about how individuals with a single SUD diagnosis (relating to only one substance) compare to individuals with poly-SUD diagnoses (relating to more than one substance) on substance use and PTSD treatment outcomes. To address this gap in the literature, we utilized data from a larger study investigating a 12-week integrated, exposure-based treatment (i.e., Concurrent Treatment of PTSD and Substance Use Disorders using Prolonged Exposure, or COPE) to examine treatment outcomes by single vs. poly-SUD status. MethodParticipants were 54 Veterans (92.6% male, average age = 39.72) categorized as having single SUD (n = 39) or poly-SUD (n = 15). T-tests characterized group differences in baseline demographics and presenting symptomatology. Multilevel models examined differences in treatment trajectories between participants with single vs. poly-SUD. ResultsGroups did not differ on baseline frequency of substance use, PTSD symptoms, or treatment retention; however, individuals with poly-SUD evidenced greater reductions in percent days using substances than individuals with a single SUD, and individuals with a single SUD had greater reductions in PTSD symptoms than individuals with poly-SUD over the course of treatment. DiscussionThe findings from this exploratory study suggest that Veterans with PTSD and co-occurring poly-SUD, as compared to a single-SUD, may experience greater improvement in substance use but less improvement in PTSD symptoms during integrated treatment. Future research should identify ways to enhance treatment outcomes for individuals with poly-SUD, and to better understand mechanisms of change for this population.

Friends matter but so does their substance use: The impact of social networks on substance use, offending and wellbeing among young people attending specialist alcohol and drug treatment services

Aims: The current study assesses the impact of youth drug treatment on substance use, offending and wellbeing in a sample of young people recruited from specialist youth alcohol and drug treatment. The paper examines the impact of treatment engagement on the size and substance use profile of the young person's social network and hypothesises that the best treatment outcomes are associated with maintaining the size of the young person's social network but changing its composition to reduce the representation of substance use in social networks. Methods: A cohort study of 112 young people (aged 16–21) engaged in specialist youth alcohol and drug treatment services in Victoria, Australia, were recruited at the beginning of treatment and re-interviewed six months later using a structured questionnaire. Findings: There were improvements in substance use, social functioning, mental health and life satisfaction from baseline to follow-up. While network size was associated with mental health and quality of life markers, only having a lower proportion of substance users in the social network was associated with lower substance use and offending at follow-up. Conclusions: Social networks are a key component of wellbeing in adolescence. This study suggests that through independent analysis of network size and network composition, both the size and the composition of social networks have an important role to play in developing interventions for adolescent substance users that will sustain behaviour changes achieved in specialist treatment.

Psycho-education for substance use and antisocial personality disorder: a randomized trial.

BackgroundAntisocial personality disorder often co-exists with drug and alcohol use disorders.MethodsThis trial examined the effectiveness of offering psycho-education for antisocial personality disorder in community substance use disorder treatment centers in Denmark. A total of 176 patients were randomly allocated to treatment as usual (TAU, n = 80) or TAU plus a psycho-educative program, Impulsive Lifestyle Counselling (ILC, n = 96) delivered by site clinicians (n = 39). Using follow-up interviews 3 and 9 months after randomization, we examined changes in drug and alcohol use (Addiction Severity Index Composite Scores), percent days abstinent (PDA) within last month, and aggression as measured with the Buss-Perry Aggression Questionnaire-Short Form and the Self-Report of Aggression and Social Behavior Measure.ResultsOverall engagement in psychological interventions was modest: 71 (76 %) of participants randomized to psycho-education attended at least one counselling session, and 21 (23 %) attended all six sessions. The Median number of sessions was 2. All patients reduced drug and alcohol problems at 9 months with small within-group effect sizes. Intention-to-treat analyses indicated significant differences between ILC and TAU in mean drugs composite score (p = .018) and in PDA (p = .041) at 3 months. Aggression declined in both groups, but no differences between ILC and TAU were observed in terms of alcohol problems or aggression at any follow-up.ConclusionsModerate short-term improvements in substance use were associated with randomization to Impulsive Lifestyle Counselling. The findings support the usefulness of providing psycho-education to outpatients with antisocial personality disorder.Trial registrationISRCTN registry, ISRCTN67266318, 17/7/2012Electronic supplementary materialThe online version of this article (doi:10.1186/s12888-015-0661-0) contains supplementary material, which is available to authorized users.

The impact of addiction medications on treatment outcomes for persons with co-occurring PTSD and opioid use disorders.

Previous research has been inconclusive about whether adding psychosocial treatment to medication assisted treatment (MAT) improves outcomes for patients with co-occurring psychiatric and opioid use disorders. This study evaluated the impact of MAT and psychosocial therapies on treatment outcomes for patients with co-occurring opioid use disorders and PTSD. Patients meeting criteria for PTSD and substance use disorders were randomly assigned to one of three treatment conditions: Standard Care (SC) alone, Integrated Cognitive Behavioral Therapy (ICBT) plus SC, or Individual Addiction Counseling (IAC) plus SC. Substance use and psychiatric symptoms were assessed at baseline and 6 months. Only patients with opioid use disorders were included in the present analyses (n = 126). Two-way ANOVAS and logistic regression analyses were used to examine associations between treatment conditions and MAT, for substance use and psychiatric outcomes. MAT patients receiving ICBT had significantly decreased odds of a positive urine drug screen, compared to non-MAT patients receiving SC alone (OR = .07, 95% CI = .01, .81, p = .03). For PTSD symptoms, a significant MAT by psychosocial treatment condition interaction demonstrated that MAT patients had comparable declines in PTSD symptoms regardless of psychosocial treatment type (F(2, 88) = 4.74, p = .011). Non-MAT patients in ICBT had significantly larger reductions in PTSD. For patients with co-occurring opioid use disorders and PTSD, MAT plus ICBT is associated with more significant improvement in substance use. For non-MAT patients, ICBT is most beneficial for PTSD symptoms.

Chronic Physical Health Problems Moderate Changes in Depression and Substance Use Among Dual Diagnosed Individuals During and After Treatment

Background: Physical illnesses frequently co-occur with depression and substance use disorders and may impact their improvement. Physical illness symptoms may overlap with or exacerbate somatic symptoms of depression. Individuals may use substances to cope with symptoms of physical illness. Objectives: We examined whether chronic physical health problems moderated changes in depression and substance use among dual diagnosed individuals during and in the year following treatment. Methods: Participants were recruited from a Veterans Affairs dual diagnosis outpatient program between March 2000 and November 2007 and were randomized to either Integrated Cognitive-Behavioral Therapy or Twelve-Step Facilitation Therapy. A total of 214 veterans with assessment data for the variables of interest were included in analyses. Participants completed quarterly depression, substance use, and health assessments over an 18 month period. We used linear-mixed effects models to analyze patterns of change for depression and substance use. Results: Individuals with severe chronic health problems and higher intake depression showed slower improvements in both nonsomatic and somatic depression symptoms. Individuals with severe chronic health problems and higher midtreatment substance use showed less improvement in substance use. Conclusions: Assessing and addressing physical health issues during depression and substance use disorder treatment may improve outcomes.

Do improvements in substance use and mental health symptoms during treatment translate to long-term outcomes in the opposite domain?

Providers who treat adolescents with co-occurring substance use and mental health issues may prioritize treatment of one set of symptoms believing that improvements in one domain will result in improvements of the other. However, limited empirical data for adolescents provide evidence of such “spillover effects.” Using data from 2900 youth in an outpatient treatment, we examined whether during-treatment changes in substance use or mental health symptoms predicted 12-month outcomes in the analogous and opposite domains. There was very little evidence of spillover effects, only that youth with no internal distress at 0 and 3months reported lower levels of substance use problems at 12-months relative to youth with internal distress that stayed the same from 0 to 3months. These findings suggest that providers treat both sets of substance use and mental health symptoms in an integrated manner given that these symptoms commonly co-occur among youth with either set.

Psychometric Evaluation of the Multidimensional Assessment of Social Anxiety Before and After Cognitive Behavioral Therapy for Social Anxiety Disorder

Due to ongoing criticism of the current diagnostic system, hybrid models of psychopathology, involving the combination of the categorical approach to diagnoses with shared symptom dimensions that are common across various disorders, have received increasing attention in the literature for the depressive and anxiety disorders. One of the few empirically-derived hybrid models was recently developed for social anxiety disorder (SOC) and subsequently led to a self-report measure entitled the Multidimensional Assessment of Social Anxiety (MASA). Although initial support has been provided for the psychometric properties of the MASA, additional research is needed. The present study investigated the internal consistency, convergent and discriminant validity, and sensitivity to detect treatment changes of the MASA scales in 116 participants with SOC that completed the measure at pretreatment and posttreatment during a trial of group cognitive behavioral therapy (CBT) for SOC. The MASA scales demonstrated acceptable sensitivity to detect symptom changes during treatment, convergent validity with related measures of SOC, and internal consistency. In addition, the observed pattern of symptom changes across the MASA scales appeared to be most consistent with the goals/techniques involved in CBT for SOC (e.g., largest improvements in behavioral avoidance; smallest improvements in substance use). Together, these findings provide additional support for psychometric properties of the MASA scales as well as the growing movement towards transdiagnostic assessment and treatment practices.

12-step facilitation for the dually diagnosed: A randomized clinical trial

There are few clinical trials of 12-step treatments for individuals with serious mental illness and alcohol or drug dependence. This randomized trial assessed the effects of adding a 12-session 12-step facilitation therapy (TSF), adapted from that used in Project MATCH, to treatment as usual in an outpatient dual diagnosis program. Participants were 121 individuals dually diagnosed with alcohol dependence and a serious mental disorder, followed during 12 weeks of treatment and 36 weeks post-treatment. Participants receiving TSF had greater participation in 12-step programs, but did not demonstrate greater improvement in alcohol and drug use. However, considered dimensionally, greater participation in TSF was associated with greater improvement in substance use, and greater 12-step participation predicted decreases in frequency and intensity of drinking. Findings suggest that future work with TSF in this population should focus on maximizing exposure to TSF, and maximizing the effect of TSF on 12-step participation.
