A systematic review of reinforcement-based interventions for substance use: Efficacy, mechanisms of action, and moderators of treatment effects.

BACKGROUND: Brief reinforcement-based psychosocial interventions such as behavioral activation (BA) and behavioral economics (BE) address imbalances in the reinforcement system that are strongly implicated in substance use. The present study reviewed a growing body of intervention studies that tested the efficacy of BA or BE in addressing substance use outcomes. The study also reviewed a smaller body of evidence exploring mechanisms of action and moderators of treatment efficacy for substance use outcomes. METHOD: A comprehensive literature search of four databases was conducted to identify studies that tested either BA or BE interventions targeting outcomes and/or mechanisms of action specific to substance use. The search yielded 12 studies that met these criteria. Ten studies reported main outcomes of BA/BE interventions targeting substance use outcomes (N = 7 BA; N = 3 BE). Two additional studies addressed mechanisms of change by conducting secondary analyses of data from one of the other ten studies. Eight of the twelve studies tested mechanisms of change and/or moderators related to substance use. RESULTS: Among all ten outcome studies, 100% provided evidence suggesting efficacy of BA/BE in targeting substance use and/or use-related problems. In 90% (9/10) of studies, the BA/BE intervention condition evidenced significantly higher abstinence rates compared to controls and/or significant decreases in substance use from baseline. Most studies that assessed substance use-related problems (83%; 5/6) reported significant decreases in use-related problems. The majority of studies (80%; 8/10) reported medium to large effect sizes. The pattern of findings was similar for BA and BE interventions. Eight studies assessed change in mechanism of action and 38% (3/8) identified mechanisms of action, however, only two conducted a formal test of whether this variable mediated the relationship between condition and outcome. Two studies tested and identified significant moderators of treatment efficacy. CONCLUSIONS: Preliminary evidence supports the efficacy of reinforcement-based interventions in targeting substance use outcomes. The mechanisms driving BA/BE efficacy and factors that may moderate treatment effects are not sufficiently clear from the studies available and require further examination, although existing data does suggest promise and provides clues for next steps.

Pilot Randomized Trial of a Self-Help Behavioral Activation Mobile App for Utilization in Primary Care.

Mobile technologies can be leveraged to meet the need for evidence-based psychological depression treatment via primary care. The purpose of the present study was to preliminarily examine the feasibility and efficacy of a self-help brief behavioral activation mobile application (app; "Moodivate") for depressive symptoms among adults treated via primary care. Participants (N = 52) were recruited from primary care practices between January and December 2017 and were randomized 2:2:1 to receive (a) Moodivate, (b) an active control cognitive-behavioral therapy-based mobile app ("MoodKit"), or (c) treatment as usual (TAU; no app). Participants completed assessments of depressive symptoms weekly for 8 weeks. App analytics data were captured to examine Moodivate feasibility (analytics unavailable for control app). Moodivate participants on average had 46.76 (SD = 30.10) app sessions throughout the trial duration, spent 3.50 (2.76) minutes using the app per session, and spent 120.76 (101.02) minutes using the app in total throughout the trial. Nearly 70% of Moodivate participants continued to use the app 1 month after trial enrollment and 50% at the end of the 8-week follow-up period. A generalized estimating equation model examining change in depressive symptoms over time by treatment condition indicated a significant interaction between time and treatment condition (χ2 = 42.21, df = 14, p < .001). As compared to TAU, participants in both app conditions evidenced significant decreases in depressive symptoms over time, and these treatment gains were sustained across the trial period. These results preliminarily indicate feasibility of Moodivate as well as efficacy of both Moodivate and MoodKit for the treatment of depression among adults recruited via primary care. Future studies should focus on larger-scale examinations of treatment efficacy and effectiveness across primary care settings.

Pilot randomized controlled trial of a Spanish-language Behavioral Activation mobile app (¡Aptívate!) for the treatment of depressive symptoms among united states Latinx adults with limited English proficiency.

BACKGROUND: To address the need for disseminable, evidence-based depression treatment options for Latinx adults with limited English proficiency (LEP), our team developed ¡Aptívate!, a Spanish-language Behavioral Activation self-help mobile application. Primary aims of this study were to: 1) examine feasibility and uptake of ¡Aptívate! among depressed Latinx adults with LEP and 2) preliminarily examine ¡Aptívate! efficacy for depression treatment. METHODS: Participants (N = 42) with elevated depressive symptoms were randomized 2:1:1 to: 1) ¡Aptívate! (n = 22), 2) an active control Spanish-language app ("iCouch CBT"; n = 9), or 3) Treatment As Usual (i.e., no app; n = 11). Feasibility was assessed via self-reported app utilization and app analytics data. Depressive symptoms were assessed weekly for eight weeks via self report. RESULTS: All ¡Aptívate! participants used the app at least once, 81.8% of participants used the app ≥8 times, and 36.4% of participants used the app ≥56 times. Weekly retention was strong: 72.7% and 50% of participants continued to use the app at one- and two-months post-enrollment, respectively. Generalized Estimating Equation models indicated a significant interaction between time and treatment, such that ¡Aptívate! participants reported significantly lower depressive symptoms over time than TAU. Depressive symptoms did not differ on average across time between the iCouch and TAU conditions, nor between iCouch and ¡Aptívate!. LIMITATIONS: Limitations include small sample size, limited follow-up, and lack of analytics data for the active control condition. CONCLUSIONS: With further research, ¡Aptívate! may offer a feasible, efficacious approach to extend the reach of evidence-based depression treatment for Latinx adults with LEP.

An experimental paradigm examining the influence of frustration on risk-taking behavior.

The present study examined the impact of frustration on risk-taking in college students with low and high ADHD symptomatology (L-ADHD and H-ADHD). Participants completed the Balloon Analogue Risk Task (BART) following induced frustration from a mood manipulation task (experimental session) and following no mood manipulation (control session). A manipulation check revealed a significant three-way interaction where the H-ADHD group reported higher frustration levels compared to the L-ADHD group, particularly in response to the frustration induction in the experimental condition. Primary results revealed that the L-ADHD group exploded significantly fewer balloons in the experimental condition compared to the control condition; there was a nonsignificant difference of balloon explosions across conditions for the H-ADHD group. The study provides initial laboratory-based support for the impact of frustration on the risk behavior of those with low and high levels of ADHD, with potential implications for future studies and ultimately for intervention.

¡Aptívate!: A Spanish-language behavioral activation mobile application for delivery via primary care.

Treatment for depression is a core health disparity for Latino/as in the United States. U.S. Latino/as are most likely to report depressive symptoms to primary care physicians, who often have limited resources for providing evidence-based psychological depression treatment. This limited treatment accessibility is further compounded by additional treatment barriers, including stigma related to seeking mental health treatment and limited English proficiency. Mobile technologies, including smartphones and mobile applications (apps) delivered via smartphone, are promising for addressing this treatment need. Herein, we discuss the development of a Spanish-language brief behavioral activation mobile application, ¡Aptívate!, that was developed to disseminate depression-based psychological treatment via primary care to Spanish-speaking Latino/as. This article focuses on the description of (a) rationale for ¡Aptívate! treatment development, (b) treatment components, and (c) a clinical case example describing potential implementation in primary care.

An Examination of the Impact of Childhood Emotional Abuse and Gender on Cannabis Use Trajectories among Community Youth.

Cannabis is the most frequently used illicit substance among youth, with rates of cannabis use escalating across adolescence. One potential factor predicting cannabis use among youth is childhood emotional abuse (CEA), which has been associated with substance use behaviors more broadly. Although CEA may be associated with increased cannabis use in general, it is likely that sex may have an impact on these relations, given that girls are more likely to use substances following abuse experiences than boys. The purpose of the current study as to examine longitudinal relations between CEA and gender on cannabis use during adolescence. The current study included a sample of 206 9th grade community youth (120 boys; Mage = 14.10, 55% European-American) followed annually through the 12th grade. CEA was assessed with the Childhood Trauma Questionnaire and cannabis use was assessed with the Youth Risk Behavior Survey. A latent growth model was utilized to examine cannabis use trajectories from grades 9-12. Within our initial model, elevated baseline use was associated with male gender and more severe CEA. Significant predictors of increases in cannabis use over time included elevated baseline alcohol use and the interaction between gender and CEA, such that girls with the most severe CEA had the greatest increases in cannabis use over time. These results suggest the importance of addressing CEA among adolescent girls. Given that cannabis use during adolescence is associated with a host of negative outcomes, targeted efforts to reduce use, through prevention and intervention efforts, is critical.

Development and Preliminary Feasibility Study of a Brief Behavioral Activation Mobile Application (Behavioral Apptivation) to Be Used in Conjunction With Ongoing Therapy.

Depressive symptoms are the most frequently treated psychiatric condition in the United States. Brief behavioral activation treatment for depression (BATD) is a popular, evidence-based psychotherapy with strong research support for the treatment of depression. In this paper, we describe the development and initial pilot feasibility testing of a BATD mobile application (Behavioral Apptivation) to be used by patients and therapists in conjunction with BATD therapy. We present information regarding the app development process as well as results from a small open-label feasibility trial of the app utilized in conjunction with individual BATD. We include a case series from the open-label trial highlighting how Behavioral Apptivation can be utilized in clinical practice.

Current directions in laboratory studies of personality pathology: Examples from borderline personality disorder, psychopathy, and schizotypy.

Much of the earliest research on personality pathology was observational and descriptive in nature, drawing heavily on subjective self-reports, however, the last 20 years have seen a surge of interest in laboratory-based studies. Laboratory research offers a number of benefits for researchers interested in personality disorders and personality pathology including the opportunities to use objective performance-based and behavioral measures, reveal the neuropsychological and biobehavioral processes that may help shape the experience and behavior of individuals with personality disorders, and create experimental designs that allow researchers to systematically explore the effect of context on emotional, behavioral and cognitive responding. Along with these benefits, laboratory research on personality disorders has its share of methodological and interpretive challenges and raise several key questions, including (a) How should we interpret findings that diverge from theory-driven predictions? (b) How do we reconcile discrepant results from subjective and performance-based assessments? and (c) Are these discrepancies due to methodological artifact, a hallmark of the disorder, or cause for theoretical reconsideration? The goal of this article is to review studies aimed at answering a key research question in the domains of borderline personality disorder, psychopathy, and schizotypy. Our review highlights significant progress in laboratory research on personality disorders, and identifies challenges that must be addressed to capitalize on the promise of laboratory methods. It is our hope that future experimental work proceeds with an eye toward theoretical coherence, methodological rigor, ecological validity, and clinical utility. (PsycINFO Database Record

Stability of Attachment Style in Adolescence: An Empirical Test of Alternative Developmental Processes.

Few studies have examined stability and change in attachment during adolescence. This 5-year longitudinal study (a) examined whether prototype or revisionist developmental dynamics better characterized patterns of stability and change in adolescent attachment (at T1, N = 176; Mage  = 14.0 years, SD = 0.9), (b) tested potential moderators of prototype-like attachment stability, and (c) compared attachment stability in adolescence to stability in adulthood. The results supported the prototype model, which assumes that there is a stable, enduring factor underlying stability and change in attachment. Exploratory moderation analyses revealed that family conflict, parental separation or divorce, minority status, and male sex might undermine the prototype-like stability of adolescent attachment. Stability of attachment was lower in adolescence relative to adulthood.

Moodivate: A self-help behavioral activation mobile app for utilization in primary care-Development and clinical considerations.

Depressive symptoms are highly prevalent and are associated with considerable functional impairment, significant public health costs, and heightened mortality risk. Individuals experiencing impairment due to depressive symptomatology are most likely to report their symptoms to a primary care provider. As such, national guidelines highlight the need to assess and effectively treat depression via primary care. Despite these guidelines, the dissemination of evidence-based psychotherapy via primary care is limited, likely due to both provider- and patient-level treatment barriers. Mobile health (mHealth) technologies are promising for addressing these barriers and for promoting uptake of evidence-based depression treatment. Among evidence-based psychotherapies for depression, brief Behavioral Activation Treatment for Depression (BATD) has shown great promise and is particularly amenable to mHealth delivery. Herein, we discuss the development of a BATD mobile application, Moodivate, that was developed in order to disseminate BATD via primary care. This paper focuses on description of (1) rationale for Moodivate treatment development, (2) Moodivate treatment components, (3) ongoing clinical trial evaluation of Moodivate, and (4) clinical considerations for incorporating Moodivate into clinical practice.

Distress tolerance interacts with circumstances, motivation, and readiness to predict substance abuse treatment retention.

BACKGROUND: Our understanding of the conditions that influence substance abuse treatment retention in urban African American substance users is limited. This study examined the interacting effect of circumstances, motivation, and readiness (CMR) with distress tolerance to predict substance abuse treatment retention in a sample of urban African American treatment-seeking substance users. METHODS: Data were collected from 81 African American substance users entering residential substance abuse treatment facility in an urban setting. Participants completed self-reported measures on CMR and distress tolerance. In addition, participants were assessed on psychiatric comorbidities, substance use severity, number of previous treatments, and demographic characteristics. Data on substance abuse treatment retention were obtained using administrative records of the treatment center. RESULTS: Logistic regression analysis found that the interaction of CMR and distress tolerance was significant in predicting substance abuse treatment retention. Higher score on CMR was significantly associated with increased likelihood of treatment retention in substance users with higher distress tolerance, but not in substance users with lower distress tolerance. CONCLUSIONS: Findings of the study indicate that at higher level of distress tolerance, favorable external circumstances, higher internal motivation, and greater readiness to treatment are important indicators of substance abuse treatment retention. The study highlights the need for assessing CMR and distress tolerance levels among substance users entering treatment, and providing targeted interventions to increase substance abuse treatment retention and subsequent recovery from substance abuse among urban African American substance users.

A Prospective Examination of the Relations Between Emotional Abuse and Anxiety: Moderation by Distress Tolerance.

Anxiety, the most common and impairing psychological problem experienced by youth, is associated with numerous individual and environmental factors. Two such factors include childhood emotional abuse (CEA) and low distress tolerance (DT). The current study aimed to understand how CEA and low DT impacted anxiety symptoms measured annually across 5 years among a community sample of youth. We hypothesized DT would moderate the relationship between CEA and anxiety, such that youth with higher levels of CEA and lower levels of DT would have elevated anxiety over time. Community youth (N = 244) were annually assessed across 5 years using the Revised Child Anxiety and Depression Scale, Childhood Trauma Questionnaire, and Behavioral Indicator of Resiliency to Distress. Higher CEA at baseline was associated with higher anxiety at baseline, higher anxiety at each annual assessment, and with greater overall decreases in anxiety over time. Lower DT was associated with higher anxiety at baseline, but did not predict changes in anxiety over time. Baseline DT significantly moderated the relationship between baseline CEA and anxiety, such that youth with both higher CEA and lower DT had the highest anxiety at each annual assessment. Youth with lower DT and higher CEA scores had the highest level of anxiety symptoms across time.

Synthetic cannabinoids to avoid urine drug screens: Implications for contingency management and other treatments for drug dependence.

Contingency management (CM) is an effective treatment for substance use dependence. Within CM, rewards or vouchers promote continued abstinence by acting as alternative reinforcers to substance use. However, CM relies on the use of accurate biochemical verification methods, such as urinalysis, to verify abstinence. Synthetic cannabinoids (SCs) pose a risk for CM treatment because they are not easily detected by common urinalysis techniques. Although SCs pose a risk, there is limited information regarding current rates of SC use within substance dependent populations as well as rates of substance use and psychiatric disorders among those who use SCs in treatment. We discuss emerging research on these topics and potential implications for CM treatments. Findings suggest CM researchers should test for and query SC use among those being treated for cannabis and cocaine use problems as well as among younger populations of substance users. Implications of other novel psychoactive substances for drug treatment and drug urinalysis are also discussed.

When Parents and Adolescents Disagree About Disagreeing: Observed Parent-Adolescent Communication Predicts Informant Discrepancies About Conflict.

Adolescence is accompanied by increased stress in the parent-adolescent relationship, which frequently results in conflict. Researchers often rely on self-reports to measure conflict, but these reports are frequently discrepant from one another. In two studies, we examined the extent to which communication observed during parent-adolescent discussions of conflict were associated with discrepancies in reports about conflict. We also examined links between informant depressive symptoms and discrepancies. Across studies, observed parent-adolescent conflict behaviors consistently predicted absolute discrepancies in reports of conflict. Informant depressive symptoms sometimes predicted directional discrepancies in reports. Results suggest that informant discrepancies about conflict may stem, in part, from a lack of open communication in the relationship.

Integrating Motivational Interviewing and Brief Behavioral Activation Therapy: Theoretical and Practical Considerations.

Behavioral Activation and specifically the Brief Behavioral Activation Therapy for Depression (BATD) has a strong record of empirical support but its focus on practical out of session activation-based assignments can lead to poor levels of adherence if efforts to enhance motivation are not prioritized. Towards this end, this manuscript describes the assimilative integration of Motivational Interviewing (MI) and BATD to improve clinical outcomes by integrating MI's focus on building and maintaining motivation to change into BATD. The manuscript provides an overview of MI and BATD, theoretical issue raised in integrating the two approaches, and examples of how this integration results in a nondirective and motivation-focused approach to conducting BATD.

Adolescent Callous-Unemotional Traits and Parental Knowledge as Predictors of Unprotected Sex Among Youth.

Risky sexual behavior among adolescents is common and results in many negative consequences. The present study investigated longitudinal predictors of adolescents' likelihood of engaging in unprotected sexual intercourse. Parental knowledge, or the extent to which parents know about their children's activities, whereabouts, and friendships, is a robust predictor of youth risk behavior, including risky sexual behavior. However, parenting practices are typically less potent as predictors of subsequent behavior among youth with high levels of callous-unemotional (CU) traits. We conducted three logistic regression models, each of which examined parental knowledge in a different way (through child report, parent report, and a discrepancy score), allowing us to examine parental knowledge, CU traits, and their interaction as predictors of adolescents' subsequent engagement in sex without a condom. Results indicated that adolescents who perceived their parents to possess greater knowledge were less likely to engage in unprotected sex. Higher parent report of parental knowledge was also related to decreased likelihood of engaging in unprotected sex, but only for adolescents with high levels of CU traits. In addition, greater discrepancy between parent and adolescent reports of parental knowledge was related to increased likelihood of engaging in unprotected sex, but only for adolescents with low levels of CU traits. Results highlight the importance of considering both parent and adolescent perceptions of parental knowledge and have important implications for prevention and intervention efforts.

Maternal risk taking on the balloon analogue risk task as a prospective predictor of youth alcohol use escalation.

The transition from late childhood through middle adolescence represents a critical developmental period during which there is a rapid increase in the initiation and escalation of alcohol use. Alcohol use is part of a constellation of risk taking behaviors that increase during this developmental transition, which can be explained by environmental and genetic factors. Social learning theory (SLT) implicates observations of parental drinking in the development of alcohol use in youth. Parental risk taking more broadly has not previously been examined as a factor predictive of alcohol use escalation in youth across adolescence. The current study examined the relative contributions of maternal risk taking on the Balloon Analogue Risk Task (BART) and maternal alcohol use in the prediction of alcohol escalation among youth over three years. Participants were a sample of 245 youth (55.0% male, 49.6% Caucasian) who participated annually between grades 8 and 10, drawn from a larger study of adolescent risk taking. Within our sample, maternal risk taking, as measured by the BART, predicted increases in alcohol use. Interestingly, maternal alcohol use and other youth factors were not predictive of escalations in youth alcohol use. Our findings suggest the importance of considering maternal riskiness more broadly, rather than solely focusing on maternal alcohol use when attempting to understand youth alcohol use across adolescence. These findings emphasize the relevance of maternal risk taking as measured by a behavioral task and suggest a general level of riskiness displayed by mothers might encourage youth to behave in a riskier manner themselves.

Rapid-response impulsivity: definitions, measurement issues, and clinical implications.

Impulsivity is a multifaceted construct that is a core feature of multiple psychiatric conditions and personality disorders. However, progress in understanding and treating impulsivity is limited by a lack of precision and consistency in its definition and assessment. Rapid-response impulsivity (RRI) represents a tendency toward immediate action that occurs with diminished forethought and is out of context with the present demands of the environment. Experts from the International Society for Research on Impulsivity (InSRI) met to discuss and evaluate RRI measures in terms of reliability, sensitivity, and validity, with the goal of helping researchers and clinicians make informed decisions about the use and interpretation of findings from RRI measures. Their recommendations are described in this article. Commonly used clinical and preclinical RRI tasks are described, and considerations are provided to guide task selection. Tasks measuring two conceptually and neurobiologically distinct types of RRI, "refraining from action initiation" (RAI) and "stopping an ongoing action" (SOA) are described. RAI and SOA tasks capture distinct aspects of RRI that may relate to distinct clinical outcomes. The InSRI group recommends that (a) selection of RRI measures should be informed by careful consideration of the strengths, limitations, and practical considerations of the available measures; (b) researchers use both RAI and SOA tasks in RRI studies to allow for direct comparison of RRI types and examination of their associations with clinically relevant measures; and (c) similar considerations be made for human and nonhuman studies in an effort to harmonize and integrate preclinical and clinical research.

Choice impulsivity: Definitions, measurement issues, and clinical implications.

Impulsivity critically relates to many psychiatric disorders. Given the multifaceted construct that impulsivity represents, defining core aspects of impulsivity is vital for the assessment and understanding of clinical conditions. Choice impulsivity (CI), involving the preferential selection of smaller sooner rewards over larger later rewards, represents one important type of impulsivity. The International Society for Research on Impulsivity (InSRI) convened to discuss the definition and assessment of CI and provide recommendations regarding measurement across species. Commonly used preclinical and clinical CI behavioral tasks are described, and considerations for each task are provided to guide CI task selection. Differences in assessment of CI (self-report, behavioral) and calculating CI indices (e.g., area-under-the-curve, indifference point, and steepness of discounting curve) are discussed along with properties of specific behavioral tasks used in preclinical and clinical settings. The InSRI group recommends inclusion of measures of CI in human studies examining impulsivity. Animal studies examining impulsivity should also include assessments of CI and these measures should be harmonized in accordance with human studies of the disorders being modeled in the preclinical investigations. The choice of specific CI measures to be included should be based on the goals of the study and existing preclinical and clinical literature using established CI measures.

Parental knowledge of adolescent activities: links with parental attachment style and adolescent substance use.

Parents' knowledge of their adolescents' whereabouts and activities is a robust predictor of adolescent risk behavior, including the use of drugs and alcohol. Surprisingly few studies have attempted to identify parental characteristics that are associated with the degree of parental knowledge. The present study is the first to examine how parental attachment style relates to mother, father, and adolescent reports of parental knowledge. Further, we used structural equation modeling to test the associations among parents' attachment styles, reports of parental knowledge, and adolescents' alcohol and marijuana use. Participants included 203 adolescents (M age = 14.02, SD = .91) living in 2-parent households and their parent(s). As predicted, mothers' and fathers' insecure attachment styles were negatively associated with self-reported and adolescent-reported parental knowledge, and all 3 reports of parental knowledge were negatively related to adolescent substance use. Mothers' and fathers' attachment styles were unrelated to adolescent substance use. However, evidence emerged for indirect effects of parental attachment style on adolescent substance use through reports of parental knowledge. Implications for prevention efforts and the importance of multiple reporters within the family are discussed.
