Daily drinking and social network interactions in network support treatment.

OBJECTIVE: Social networks can be powerful determinants of drinking. Network Support (NS) treatment was designed to help persons with alcohol use disorder alter their social network to be more supportive of abstinence and less supportive of drinking. The present study was intended to determine how NS treatment altered behavior on a daily basis. It was expected that, relative to those treated in a packaged cognitive-behavioral treatment (PCBT), NS patients would report fewer daily contacts with drinking persons and increased contacts with nondrinking persons. METHOD: Patients (N = 193) treated in our second NS trial provided daily recordings of drinks consumed, urge to drink, and self-efficacy for not drinking, as well as reports of associations with drinking and nondrinking friends, via an interactive voice response system. Daily recordings (N = 146) were collected during the first 6 months of the 27-month study. Multilevel modeling was used to analyze daily network variables over time by treatment. Time-varying effect model (TVEM) analyses were also conducted to assess the influence of daily-varying social contacts on daily drinking, drinking urges, and self-efficacy. RESULTS: Consistent with hypotheses, NS patients reported significantly less daily drinking associated with contacts with drinkers than did PCBT patients. Patients in both treatments reported increases in self-efficacy and decreases in urges to drink over days as a function of contact with nondrinkers. CONCLUSIONS: NS treatment was successful in helping patients change their social networks, as well as their responses to social influences, and those changes had effects on day-to-day drinking levels.

Momentary coping and marijuana use in treated adults: Exploring mechanisms of treatment.

OBJECTIVE: This study was designed to test the hypothesis that an Individualized Assessment and Treatment Program (IATP) for cannabis use disorder (CUD) that utilized experience sampling (ES) data to individualize treatment would be more effective at eliciting adaptive coping responses in high-risk situations than a more conventional cognitive-behavioral treatment. It was further expected that increases in momentary adaptive coping, positive affect, and self-efficacy expectancies would mediate the effects of treatment on momentary drug use in the hours following a temptation-to-use episode. METHOD: The participants were 198 adults seeking treatment for CUD, randomized to receive either a conventional motivational enhancement + cognitive-behavioral treatment (MET-CBT) with or without contingency management (CM) or an IATP with or without CM. Treatment took place over nine individual sessions, and follow-ups were conducted out to 14 months post-intake. ES data were recorded in all treatments at pretreatment, and at various points during and after treatment. RESULTS: Analyses of ES data indicated that the IATP conditions yielded greater increases in use of adaptive coping skills during temptation episodes than did the MET-CBT conditions. Mediation analyses supported the hypothesis that momentary use of coping skills mediates the effects of IATP on use or non-use of marijuana in the hours following a temptation episode. CONCLUSIONS: Use of an individualized coping treatment approach results in lower use of marijuana in high-risk situations, and actual utilization of adaptive coping appears to be a mechanism of that effect.

Individualized assessment and treatment program (IATP) for cannabis use disorder: Randomized controlled trial with and without contingency management.

This study tested a new approach to the treatment of cannabis use disorder (CUD). CUD is difficult to treat, and achieving abstinence is particularly difficult. The individualized assessment and treatment program (IATP) was intended to address this problem by providing a highly individualized approach to the training of coping skills most relevant for each individual. To do this, an experience sampling procedure was used prior to treatment to record patients' marijuana use behavior and associated thoughts, feelings, coping behaviors, and situations. This information was used by therapists to plan treatment that would address the specific strengths and weaknesses of each patient in drug-use situations. The present study tested IATP against a conventional combined motivational enhancement cognitive-behavioral treatment (MET-CBT), with or without the addition of contingency management (CM) for abstinence. The patients were 198 men and women randomly assigned to 1 of 4 nine-session treatment conditions: MET-CBT, MET-CBT-CM, IATP, or IATP-CM. Patients were assessed out to 14 months. Planned contrasts indicated that the IATP conditions yielded greater levels of abstinence than did the MET-CBT conditions. The addition of CM did not bolster the performance of IATP but did do so for MET-CBT. As expected, IATP lead to greater use of coping skills than did the MET-CBT conditions. However, coping skills use was not a significant predictor of outcome when other variables were in the same analyses. Self-efficacy was a robust predictor and mediator of outcome. We suggest that the IATP may act by enhancing self-efficacy. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Coping skills training and contingency management treatments for marijuana dependence: exploring mechanisms of behavior change.

AIMS: Achieving abstinence in the treatment of marijuana dependence has been difficult. To date the most successful treatments have included combinations of motivation enhancement treatment (MET) plus cognitive-behavioral coping skills training (CBT) and/or contingency management (ContM) approaches. Although these treatment approaches are theoretically based, their mechanisms of action have not been explored fully. The purpose of the present study was to explore mechanisms of behavior change from a marijuana treatment trial in which CBT and ContM were evaluated separately and in combination. DESIGN: A dismantling design was used in the context of a randomized clinical trial. SETTING: The setting was an out-patient treatment research facility located in a university medical center. PARTICIPANTS: Participants were 240 adult marijuana smokers, meeting criteria for cannabis dependence. INTERVENTIONS: Participants were assigned to one of four 9-week treatment conditions: a case management control condition, MET/CBT coping skills training, ContM and MET/CBT + ContM. MEASUREMENTS: Outcome measures were total 90-day abstinence, recorded every 90 days for 12 months post-treatment. FINDINGS: Regardless of treatment condition, abstinence in near-term follow-ups was predicted most clearly by abstinence during treatment, but long-term abstinence was predicted by use of coping skills and especially by post-treatment self-efficacy for abstinence. CONCLUSIONS: It was concluded that the most efficacious treatments for marijuana dependence are likely to be those that increase self-efficacy.

Treatment response and non-response in CBT and Network Support for alcohol disorders: targeted mechanisms and common factors.

AIMS: To determine whether mechanisms of drinking behavior change that are targeted by specific treatments mediate the effects of Packaged Cognitive Behavior Therapy (PCBT) and Network Support (NS) on abstinence rates throughout 27 months. DESIGN: Secondary analysis of data from two Network Support Project randomized clinical trials, in which participants were assigned to either a case management control treatment (control) or NS treatment in trial 1, or to PCBT or NS treatment in trial 2. SETTING: An out-patient substance abuse treatment site at a university medical center in the United States. PARTICIPANTS: A total of 249 men and 154 women (n = 403) with alcohol use disorder. MEASUREMENTS: The primary outcome was membership in a treatment responder class determined by growth mixture modeling (GMM) of monthly proportion days abstinent (PDA) to 27 months. Key predictors of responder class membership included network change variables, and changes in coping scores and self-efficacy. FINDINGS: GMM analyses indicated that a three-class solution provided the best fit to the data: a treatment responder class comprising almost 55% of patients, a late relapsing class that showed post-treatment gains followed by a return to baseline drinking (12.7% of patients) and a non-responder class (32% of patients). Analyses indicated that treatment effects on responder class membership were moderated by baseline drinking (P < 0.001). PCBT effects were mediated by changes in coping scores (P < 0.05). NS treatment effects were also mediated by coping change, as well as by increases in self-efficacy and in number of abstinent friends (P < 0.05). CONCLUSIONS: Long-term success in Packaged Cognitive Behavior Therapy and Network Support treatments for alcohol use disorder appears to be mediated by both general mechanisms (developing coping skills and self-efficacy) and treatment-targeted mechanisms (developing network strategies that emphasize social support and avoiding friends who drink).

Changing network support for drinking: initial findings from the network support project.

The aim of this study was to determine whether a socially focused treatment can effect change in the patient's social network from one that reinforces drinking to one that reinforces sobriety. Alcohol dependent men and women (N = 210) recruited from the community were randomly assigned to 1 of 3 outpatient treatment conditions: network support (NS), network support + contingency management (NS + CM), or case management (CaseM; a control condition). Analysis of drinking rates for 186 participants at 15 months indicated a significant interaction effect of Treatment x Time, with both NS conditions yielding better outcomes than the CaseM condition. Analyses of social network variables at posttreatment indicated that the NS conditions did not reduce social support for drinking relative to the CaseM condition but did increase behavioral and attitudinal support for abstinence as well as Alcoholics Anonymous (AA) involvement. Both the NS variables and AA involvement variables were significantly correlated with drinking outcomes. These findings indicate that drinkers' social networks can be changed by a treatment that is specifically designed to do so, and that these changes contribute to improved drinking outcomes.

Abstinence rates following behavioral treatments for marijuana dependence.

Previous studies have noted particular difficulty in achieving abstinence among those who are marijuana dependent. The present study employed a dismantling design to determine whether adding contingency management (ContM) to motivational enhancement therapy plus cognitive behavioral therapy (MET+CBT), an intervention used in prior studies of treatment for marijuana dependence, would enhance abstinence outcomes. 240 marijuana dependent participants were recruited via advertisements and assigned to either MET+CBT, ContM-only, MET+CBT+ContM, or to a case-management control condition. All interventions involved 9 weekly 1-h sessions, except for the ContM-only condition whose sessions lasted about 15 min. ContM provided reinforcement for marijuana-free urine specimens, in the form of vouchers redeemable for goods or services. Follow-up data were collected at posttreatment and at 3-month intervals for 1 year. The two ContM conditions had superior abstinence outcomes: ContM-only had the highest abstinence rates at posttreatment, and the MET+CBT+ContM combination had the highest rates at later follow-ups. The roles of contingency management and coping skills training in the treatment of marijuana dependence are discussed.

Network Support II: Randomized controlled trial of Network Support treatment and cognitive behavioral therapy for alcohol use disorder.

BACKGROUND: The social network of those treated for alcohol use disorder can play a significant role in subsequent drinking behavior, both for better and worse. Network Support treatment was devised to teach ways to reconstruct social networks so that they are more supportive of abstinence and less supportive of drinking. For many patients this may involve engagement with AA, but other strategies are also used. PURPOSE: The current trial of Network Support treatment, building on our previous work, was intended to further enhance the ability of patients to construct abstinence-supportive social networks, and to test this approach against a strong control treatment. METHODS: Patients were 193 men and women with alcohol use disorder recruited from the community and assigned to either 12 weeks of Network Support (NS) or Packaged Cognitive-Behavioral Treatment (PCBT), and followed for 27 months. RESULTS: Results of multilevel analyses indicated that NS yielded better posttreatment results in terms of both proportion of days abstinent and drinking consequences, and equivalent improvements in 90-day abstinence, heavy drinking days and drinks per drinking day. Mediation analyses revealed that NS treatment effects were mediated by pre-post changes in abstinence self-efficacy and in social network variables, especially proportion of non-drinkers in the social network and attendance at Alcoholics Anonymous. CONCLUSION: It was concluded that helping patients enhance their abstinent social network can be effective, and may provide a useful alternative or adjunctive approach to treatment.

Coping and self-efficacy in marijuana treatment: results from the marijuana treatment project.

This study examined whether a coping-skills-based treatment for marijuana dependence operated by encouraging the use of coping skills or via other mechanisms. Participants were 450 men and women treated in the multisite Marijuana Treatment Project who were randomly assigned to motivational enhancement therapy plus cognitive-behavioral (MET-CB) treatment, motivational enhancement therapy (MET), or a delayed treatment control group. Marijuana use and coping skills were measured at baseline and at follow-ups through 15 months. Results showed that marijuana outcomes were predicted by treatment type and by coping skills use, but that the coping-skills-oriented MET-CB treatment did not result in greater use of coping skills than did the MET treatment. The results suggest that mechanisms of coping skills treatment may need to be reconceptualized.

Willpower versus "skillpower": Examining how self-efficacy works in treatment for marijuana dependence.

Self-efficacy has repeatedly been demonstrated to be a robust predictor of outcomes in the treatment of marijuana use disorders. It is not clear, however, how increases in confidence in ability to refrain from use get translated into actual improvements in drug-related outcomes. Marlatt, among others, viewed the acquisition and use of coping skills as the key to behavior change, and self-efficacy as a cognitive state that enabled coping. But that model of behavior change has not been supported, and few studies have shown that the effects of self-efficacy are mediated by coping or by other processes. The current study combined 3 marijuana treatment trials comprising 901 patients to examine the relationships between self-efficacy, coping, and potential mediators, to determine if the effects of self-efficacy on outcomes could be explained. Results of multilevel models indicated that self-efficacy was a strong predictor of adaptive outcomes in all trials, even when no active treatment was provided. Tests of mediation showed that effects of self-efficacy on marijuana use and on marijuana-related problems were partially mediated by use of coping skills and by reductions in emotional distress, but that direct effects of self-efficacy remained largely unexplained. The results are seen as supportive of efforts to improve coping skills and reduce distress in marijuana treatment, but also suggest that additional research is required to discover what is actually occurring when substance use changes, and how self-efficacy enables those changes.

Network Support treatment for alcohol dependence: gender differences in treatment mechanisms and outcomes.

OBJECTIVE: Network Support treatment was intended to help alcohol dependent patients alter their close social support networks to be more supportive of sobriety and less supportive of drinking. The purpose of the present study was to examine the differential influences of Network Support treatment on men and women. METHODS: Alcohol dependent men (n=122) and women (n=88) recruited from the community were randomly assigned to 1 of 3 12-week outpatient treatment conditions: Network Support (NS), Network Support+Contingency Management (NS+CM), or Case Management (CaseM; a control condition). Patients were then followed for a period of 27 months. Multilevel modeling was used to evaluate Sex×Treatment interaction effects on outcome variables over time. Tests of mediation were used to determine what factors might account for differential effectiveness for men or women in the NS conditions. RESULTS: Analyses of drinking-related outcome measures over the 27 months indicated that women fared less well overall, and particularly poorly in the Network Support conditions, relative to men. Tests of mediation indicated that self-efficacy change and change in the number of non-drinking close associates partially mediated the effect of NS treatments on outcome. CONCLUSIONS: It was concluded that the NS conditions failed to alter women's social networks, and may have had the effect of undermining women's self-efficacy. Network Support treatment might be applicable for women and more effective generally if particular attention is paid to understanding preexisting social support networks.

Coping skills and treatment outcomes in cognitive-behavioral and interactional group therapy for alcoholism.

In the present study 128 alcohol dependent men and women received 26 weeks of group treatment in one of two modalities: Cognitive-behavioral treatment (CBT) intended specifically to develop coping skills or interactional therapy intended to examine interpersonal relationships. Coping skills and drinking were assessed prior to and after treatment and up to 18 months after intake. Results indicated that both treatments yielded very good drinking outcomes throughout the follow-up period. Increased coping skills was a significant predictor of outcome. However, neither treatment effected greater increases in coping than the other. Specific coping-skills training was not essential for increasing the use of coping skills. The results raise questions about the efficacy of specific treatment elements of CBT in treatment of alcohol dependence.

Cognitive-Behavioral Approaches to Alcoholism Treatment.

Cognitive-behavioral theories explain alcoholism as a learned behavior that can be changed using the same behavior modification interventions employed to alter other learned behaviors. Treatment interventions teach clients the skills they need to confront or avoid everyday situations that may lead to drinking.

Searching for treatment outcome measures for use across trials.

OBJECTIVE: Inconsistencies in outcome measures across studies of treatment efficacy have made comparisons among them difficult. As a result, there is interest in identifying one or more measures that might be recommended as universal indicators of outcome. The present article seeks to identify drinking, psychosocial and/or biological variables that could be candidates for use as universal indicators of change following alcoholism treatment. METHOD: The primary data set included 128 alcohol-dependent men and women who were randomly assigned to cognitive-behavioral or interactional group treatment for 26 weekly sessions. RESULTS: The greatest changes following treatment were seen in measures of drinking and drinking consequences. Correlational analyses indicated that changes from baseline in drinking consequences were significantly associated with changes in drinking. Psychosocial and biological indicators showed much smaller changes from baseline, and these were only weakly associated with changes in drinking, indicating that they are not sensitive measures of treatment-related change. The overall pattern of these findings was replicated in the Project MATCH data set. CONCLUSIONS: It was concluded that drinking frequency and intensity measures, as well as a measure of drinking consequences, may be useful as universal indicators of alcohol treatment outcome, but that the other psychosocial and biological measures studied in these two data sets are not strong candidates for this purpose.

Behavioral treatment for marijuana dependence: randomized trial of contingency management and self-efficacy enhancement.

OBJECTIVE: The purpose of the present study was to develop a treatment for marijuana dependence specifically designed to enhance self-efficacy. METHOD: The participants were 215 marijuana-dependent men and women randomized to one of three 9-week outpatient treatments: a condition intended to enhance self-efficacy through successful completion of treatment-related tasks (motivational enhancement plus cognitive-behavioral treatment plus contingency management reinforcing completion of treatment homework; MET+CBT+CM(Homework)); a condition that controlled for all elements except for reinforcement of homework (MET+CBT+contingency management reinforcing drug abstinence; MET+CBT+CM(Abstinence)); or a case management control condition (CaseM). Participants in the two MET+CBT conditions were also asked to complete interactive voice recordings three times per week during treatment to confirm homework completion. RESULTS: All patients showed modest improvements over time through 14months, with few between-treatment effects on outcomes. Latent Class Growth Models, however, indicated that a subsample of patients did extremely well over time. This subsample was more likely to have been treated in the CM(Abstinence) condition. In turn, this treatment effect appears to have been accounted for by days of continuous abstinence accrued during treatment, and by pre-post increases in self-efficacy. CONCLUSIONS: The most effective treatments may be those that elicit abstinence while increasing self-efficacy.

The nature of coping in treatment for marijuana dependence: latent structure and validation of the Coping Strategies Scale.

The Coping Strategies Scale (CSS) was designed to assess adaptive changes in substance-use specific coping that result from treatment. This study sought to examine the latent structure of the CSS in the hope that it might shed light on the coping processes of drug users and guide the development of a brief version of the CSS. Respondents on the CSS were 751 men and women treated in 3 clinical trials for marijuana dependence. Posttreatment CSS data were analyzed to determine the nature of coping responses in patients who have been trained to use specific strategies to deal with substance use disorders. Exploratory factor analysis yielded 2 factors, categorized as problem-focused and emotion-focused coping, but confirmatory factor analysis did not support this structure. When infrequently endorsed items were removed, however, confirmatory factor analysis revealed a good fit to the data. Contrary to expectations, practical strategies that often form the basis for coping skills training, such as avoiding those who smoke, were not frequently endorsed. Problem-focused items reflected cognitive commitments to change. Emotion-focused items included cognitive reinterpretations of emotions to help manage emotional reactions. Brief versions of the CSS based on these factors showed good convergent and discriminant validity. The CSS, and the brief versions of the CSS, may prove useful in future treatment trials to evaluate effects of treatment on coping skills acquisition and utilization in substance dependent individuals.

The role of self-efficacy in the treatment of substance use disorders.

Self-efficacy is the belief that one has the ability to implement the behaviors needed to produce a desired effect. There has been growing interest in the role of self-efficacy as a predictor and/or mediator of treatment outcome in a number of domains. The present paper reviews the recent literature on self-efficacy in the substance abuse field. In numerous studies of substance abuse treatment, self-efficacy has emerged as an important predictor of outcome, or as a mediator of treatment effects. Despite these repeated positive findings, the self-efficacy concept has had little impact on the design of treatments. Since the concept was first introduced, there have been numerous suggestions regarding the means by which self-efficacy may be enhanced in clinical settings, but very little by way of empirical tests of those suggestions. This review concludes with a number of recommendations for further research to improve understanding of this potentially valuable concept and its interactions with other variables, and to develop effective strategies for enhancing self-efficacy.

Changing network support for drinking: network support project 2-year follow-up.

The Network Support Project was designed to determine whether a treatment could lead patients to change their social network from one that supports drinking to one that supports sobriety. This study reports 2-year posttreatment outcomes. Alcohol-dependent men and women (N = 210) were randomly assigned to 1 of 3 outpatient treatment conditions: network support (NS), network support + contingency management (NS + CM), or case management (CaseM, a control condition). Analysis of drinking rates indicated that the NS condition yielded up to 20% more days abstinent than the other conditions at 2 years posttreatment. NS treatment also resulted in greater increases at 15 months in social network support for abstinence, as well as in AA attendance and AA involvement than did the other conditions. Latent growth modeling suggested that social network changes were accompanied by increases in self-efficacy and coping that were strongly predictive of long-term drinking outcomes. The findings indicate that a network support treatment can effect long-term adaptive changes in drinkers' social networks and that these changes contribute to improved drinking outcomes in the long term.

Increased drinking in a trial of treatments for marijuana dependence: substance substitution?

This report examines whether participants in a study of treatments for marijuana dependence may have increased their use of alcohol when they reduced or ceased marijuana use. Participants were randomly assigned to one of four psychosocial treatments and followed at 3-month intervals for 1 year. Findings are from 207 cases with data at posttreatment and at least one other follow-up. 73% of cases reported an increase of at least 10% in drinking days over their level at intake, and 65% reported an increase of at least 10% in drinks per drinking day. Drinking increases were not related to treatment condition nor to change in marijuana use, but were related to baseline drinking: those with less baseline drinking tended to increase their drinking during treatment and those with more baseline drinking reported less drinking during treatment. Thereafter, drinking levels remained fairly stable throughout the follow-up year. The results are most likely reflective of a regression to the mean effect, and indicate that use of alcohol and marijuana are independent of one another.
