RESUMEN

Ecological momentary assessment (EMA) has been broadly used to collect real-time longitudinal data in behavioral research. Several analytic methods have been applied to EMA data to understand the changes of motivation, behavior, and emotions on a daily or within-day basis. One challenge when utilizing those methods on intensive datasets in the behavioral field is to understand when and why the methods are appropriate to investigate particular research questions. In this manuscript, we compared two widely used methods (generalized estimating equations and generalized linear mixed models) in behavioral research with three other less frequently used methods (Markov models, generalized linear mixed-effects Markov models, and differential equations) in behavioral research but widely used in other fields. The purpose of this manuscript is to illustrate the application of five distinct analytic methods to one dataset of intensive longitudinal data on drinking behavior, highlighting the utility of each method.

RESUMEN

Black mothers and their children continue to interface with the child welfare (CW) system at unacceptably high rates. With research into traditionally understood contributing factors such as poverty, substance use, mental health and intimate partner violence abounding, this study sought to identify underexamined factors that potentially sustain very high rates of CW involvement for Black mothers. A sample of 415 Black mothers who accessed financial assistance through the Temporary Assistance for Needy Families program was analyzed for the factors associated with active CW involvement. Analytic procedures included, first, independent t-test and chi-square tests to determine significant group differences. Second, logistic regression was used to test a range of psychosocial risk factors for active CW involvement. Results from our final model indicated three factors beyond those typically associated with CW involvement, number of births, age at first use of cocaine and legal involvement. The standout impact of having a history of CW involvement is also discussed. Implications for policy and practice are explored.

RESUMEN

We use dynamical systems modeling to help understand how selected intra-personal factors interact to form mechanisms of behavior change in problem drinkers. Our modeling effort illustrates the iterative process of modeling using an individual's clinical data. Due to the lack of previous work in modeling behavior change in individual patients, we build our preliminary model relying on our understandings of the psychological relationships among the variables. This model is refined and the psychological understanding is then enhanced through the iterative modeling process. Our results suggest that this is a promising direction in research in alcohol use disorders as well as other behavioral sciences.

RESUMEN

BACKGROUND: Addiction is characterized by compulsive drug seeking and substance use, yet many individuals break free of these patterns and change their behavior. Traditional candidate predictors of behavior change/persistence rely on self-reports of factors such as readiness to change. However, explicit measures only characterize top-down influences on behavior. The incentive sensitization model of addition suggests that more implicit, automatic processes, such as the tendency to approach substance cues, play a major role in behavior. METHODS: We examined implicit alcohol approach and avoidance tendencies using a reaction time (RT) task in a sample of problem drinkers with alcohol use disorder (AUD) seeking to reduce heavy drinking. We measured alcohol approach and avoidance tendencies at baseline and at outcome, 12 weeks later. We asked whether alcohol approach and avoidance tendencies (i) changed over time, (ii) related to current drinking, and (iii) predicted changes in drinking from baseline to outcome. RESULTS: Approach and avoidance tendencies did not significantly change over time, nor did they correlate with current drinking, but these tendencies at baseline did predict drinking weeks later. Faster alcohol approach was associated with greater overall drinking at outcome, and faster alcohol avoidance predicted fewer drinking days per week at outcome. Exploratory analyses examined the relationship between approach and avoidance and traditional explicit measures including appraisals of alcohol and motivation to change. Implicit approach tendencies were largely distinct from explicit measures, and approach and avoidance tendencies explained unique variance in outcome drinking. CONCLUSIONS: The current findings suggest that implicit alcohol approach and avoidance tendencies assessed via a simple reaction time task can predict relative changes in drinking weeks later. Given that many explicit measures typically used in treatment studies fail to predict who will change, approach and avoidance tendencies are promising candidates to understand individual differences in treatment responses.

RESUMEN

BACKGROUND: Helping alcohol-dependent individuals to cope with, or regulate, cue-induced craving using cognitive strategies is a therapeutic goal of cognitive behavioral therapy (CBT) for alcohol dependence. An assumption that underlies this approach is that alcohol dependence is associated with deficits in such cognitive regulation abilities. To date, however, the ability to utilize such strategies for regulation of craving has never been tested in a laboratory setting. METHODS: Here we compared 19 non-treatment-seeking, alcohol-dependent drinkers (AD) to 21 social drinkers (SD), using a laboratory task that measured the ability to reduce cue-induced alcohol craving by thinking about long-term negative consequences of drinking, which is a specific cognitive regulation strategy that is taught in CBT. The task also assessed the ability to reduce food craving elicited by high-calorie food cues using a similar strategy. RESULTS: The reduction in craving when using this cognitive regulation strategy was approximately double in SD, compared to AD, for both alcohol and food cues. Furthermore, in SD but not AD, the ability to regulate cue-induced alcohol craving was correlated with the ability to regulate food craving. There were no significant correlations found between the ability to regulate cue-induced alcohol craving and a number of self-report measures related to severity of alcohol dependence, baseline craving, impulsivity, and general self-regulation ability, for either AD or SD. CONCLUSIONS: The results suggest that alcohol dependence is associated with deficits in cognitive regulation of cue-induced craving and that these deficits are not specific to the regulation of alcohol craving, but generalize to the regulation of other appetitive states, such as food craving. Future studies may use similar procedures to address the neural and cognitive processes that underlie such regulation deficits, as well as the effects of treatments such as CBT on these processes.

RESUMEN

Men who have sex with men (MSM) remain most at risk for developing HIV infection. The best prevention in this population is to identify risk factors associated with unprotected sex. Recent research suggests that sexual sensation seeking (SSS) and level of average drinking moderates the relationship between drinking alcohol in the context of sex and risky sexual behavior in a young MSM population (ages 16-20 years). Current study is an exploratory analysis using multilevel modeling to examine if these results are consistent across a MSM population with a wider range of ages who are also heavy drinkers. Participants (n = 181) included MSM (ages 18-75 years) from a longitudinal clinical research trial. Results indicate that MSM with higher SSS were more likely to have unprotected anal sex if they drank alcohol 3 h prior to sex than those who did not, (OR = 1.07; 95 % CI 1.03-1.12). There was no significant interaction effect for average levels of drinking.

RESUMEN

A major focus of implementation science is discovering whether evidence-based approaches can be delivered with fidelity and potency in routine practice. This randomized trial compared usual care family therapy (UC-FT), implemented without a treatment manual or extramural support as the standard-of-care approach in a community clinic, to nonfamily treatment (UC-Other) for adolescent conduct and substance use disorders. The study recruited 205 adolescents (M age = 15.7 years; 52% male; 59% Hispanic American, 21% African American) from a community referral network, enrolling 63% for primary mental health problems and 37% for primary substance use problems. Clients were randomly assigned to either the UC-FT site or one of five UC-Other sites. Implementation data confirmed that UC-FT showed adherence to the family therapy approach and differentiation from UC-Other. Follow-ups were completed at 3, 6, and 12 months postbaseline. There was no between-group difference in treatment attendance. Both conditions demonstrated improvements in externalizing, internalizing, and delinquency symptoms. However, UC-FT produced greater reductions in youth-reported externalizing and internalizing among the whole sample, in delinquency among substance-using youth, and in alcohol and drug use among substance-using youth. The degree to which UC-FT outperformed UC-Other was consistent with effect sizes from controlled trials of manualized family therapy models. Nonmanualized family therapy can be effective for adolescent behavior problems within diverse populations in usual care, and it may be superior to nonfamily alternatives.

RESUMEN

BACKGROUND: A functional polymorphism (5-HTTLPR) in the promoter region of the serotonin transporter gene has been widely studied as a risk factor and moderator of treatment for a variety of psychopathologic conditions. To evaluate whether 5-HTTLPR moderates the effects of treatment to reduce heavy drinking, we studied 112 high-functioning European-American men who have sex with men (MSM). Subjects participated in a randomized clinical trial of naltrexone (NTX) and cognitive behavioral therapy (CBT) for problem drinking. METHODS: Subjects were treated for 12 weeks with 100 mg/d of oral NTX or placebo (PBO). All participants received medical management with adjusted brief behavioral compliance enhancement treatment (BBCET) alone or in combination with modified behavioral self-control therapy (MBSCT; an amalgam of motivational interviewing and CBT). Participants were genotyped for the tri-allelic 5-HTTLPR polymorphism (i.e., low-activity S' or high-activity L' alleles). RESULTS: During treatment, the number of weekly heavy drinking days (HDD; defined as 5 or more standard drinks per day) was significantly lower in subjects with the L'L' (N = 26, p = 0.015) or L'S' (N = 52, p = 0.016) genotype than those with the S'S' (N = 34) genotype regardless of treatment type. There was a significant interaction of genotype with treatment: For subjects with the S'S' genotype, the effects of MBSCT or NTX on HDD were significantly greater than the minimal intervention (i.e., BBCET or PBO, p = 0.007 and p = 0.049, respectively). In contrast, for subjects with 1 or 2 L' alleles, the effects of the more intensive psychosocial treatment (MBSCT) or NTX did not significantly differ from BBCET or PBO. CONCLUSIONS: These preliminary findings support the utility of the 5-HTTLPR polymorphism for personalizing treatment selection in problem drinkers.

RESUMEN

BACKGROUND: Mobile messaging interventions have been shown to improve outcomes across a number of mental health and health-related conditions, but there are still significant gaps in our knowledge of how to construct and deliver the most effective brief messaging interventions. Little is known about the ways in which subtle linguistic variations in message content can affect user receptivity and preferences. OBJECTIVE: The aim of this study was to determine whether any global messaging preferences existed for different types of language content, and how certain characteristics moderate those preferences, in an effort to inform the development of mobile messaging interventions. METHODS: This study examined user preferences for messages within 22 content groupings. Groupings were presented online in dyads of short messages that were identical in their subject matter, but structurally or linguistically varied. Participants were 277 individuals residing in the United States who were recruited and compensated through Amazon's Mechanical Turk (MTurk) system. Participants were instructed to select the message in each dyad that they would prefer to receive to help them achieve a personal goal of their choosing. RESULTS: Results indicate global preferences of more than 75% of subjects for certain types of messages, such as those that were grammatically correct, free of textese, benefit-oriented, polite, nonaggressive, and directive as opposed to passive, among others. For several classes of messages, few or no clear global preferences were found. There were few personality- and trait-based moderators of message preferences, but subtle manipulations of message structure, such as changing "Try to…" to "You might want to try to…" affected message choice. CONCLUSIONS: The results indicate that individuals are sensitive to variations in the linguistic content of text messages designed to help them achieve a personal goal and, in some cases, have clear preferences for one type of message over another. Global preferences were indicated for messages that contained accurate spelling and grammar, as well as messages that emphasize the positive over the negative. Research implications and a guide for developing short messages for goal-directed behaviors are presented in this paper.

RESUMEN

UNLABELLED: Personalized feedback (PF) has demonstrated effectiveness in reducing drinking. Few studies have examined its effectiveness with adult problem drinkers or its potential mediators or moderators, including developing discrepancy. This study aimed to identify potential mediators and moderators of PF provided to adult problem drinking men who have sex with men (PDMSM). METHOD: An exploratory analysis of PF provided to PDMSM in the context of modified behavioral self-control therapy (N = 90). The association of individual items of PF, severity of PF, and independently rated, in-session participant reactions to PF with drinking outcomes (mean drinks per drinking day, MDDD) were examined using correlations and logistic and linear regression. RESULTS: Significant pre-post differences in MDDD emerged. Other drug risk, family risk, and having an abnormal liver enzyme test result were significantly associated with proxies for developed discrepancy in expected directions; however, no PF item or reaction to PF predicted drinking outcomes. Severity of PF was not associated with participant reactions or drinking outcome. CONCLUSIONS: PF may be an effective intervention for PDMSM. Further research is needed to identify potential mediators and moderators of PF among adults.

RESUMEN

Effective translation of data to inform real-time patient care is lacking in addiction inpatient settings. The current study presents the optimization of an assessment report that is used by clinicians to individualize treatment. A multi-aim, iterative approach was taken, utilizing an implementation science perspective to arrive at a final version of the assessment report. This occurred at a small inpatient addiction treatment facility. Participants were all available clinical staff (N = 7; female = 71%). A quantitative survey was used for aims 1 and 2 to, respectively, assess motives and context around the report as well as evaluate its design. Aim 3 focused on optimization via semi-structured interviews. Descriptive and modified content analyses were utilized appropriately across aims. This resulted in five versions of the assessment report being created between February 2021 and August 2022, the most recent of which was adapted into patients' electronic medical records. We discuss each version of the report in depth, including clinicians' iterative feedback and researchers' perceived barriers to this translational process. The response rate was 64.3%. The current study highlights a replicable approach for optimizing the translation of assessment data into treatment for patients with disorders of addiction as well as an assessment report that could be utilized by similar facilities with a naturally low sample size.

RESUMEN

Background: There is a lack of consensus in the addiction field as to how to refer to alumni of residential treatment who no longer use substances or who reduce their use. In the literature, this label and broader identity are typically discussed in technical (amount and frequency of use) or social terms (environment and social network changes). Objective: The current paper seeks to simplify the discussion by focusing on personal labels without complex technical or social considerations. Alumni of an inpatient addiction treatment facility were asked how they refer to themselves regarding their sobriety status post-discharge. Methods: Forty-nine patients were contacted 3 months post-discharge from a residential inpatient addiction treatment (men = 67%; Mage = 47.75 years). The patients completed a post-discharge assessment that was conducted by a trained research assistant over a 20-minute video call. The current study focused on a "sobriety label" measure in which patients indicated what they want to be called. Patients also explained why they chose their answer in an open-ended question. Results: Most patients identified as in recovery (n = 29; 59.18%) followed by a sober person (n = 7; 14.29%) and four other responses. No alum selected the in remission option, which is notably a common way to refer to patients who no longer use substances. Conclusion: The current study adds a critical patient/alumni perspective to the existing body of literature and serves as a call to action for researchers to add a similar "sobriety label" measure to future assessments, studies, and batteries in effort to bring consistency to the labels, definitions, and identities that are published. This methodology of understanding how this population identifies will create uniformity in future literature and decrease the stigma surrounding addiction.


There is a history of inconsistent use of labels, definitions, and identities in the addiction treatment field. Few past studies have directly asked patients how they self-label, and it is important to ask those who use substances or who have reduced their use what they preferred to be called. This study asked a simple question to alumni of an inpatient treatment facility what they want to be called. We then asked them to explain why they chose that answer. Most alumni identified as "in recovery" or "a sober person". This simple tool can be utilized by other facilities and also highlights that many research studies are referring to individuals by terms they do not prefer (eg, "in remission").

RESUMEN

OBJECTIVE: To describe key features and the initial implementation of an employer-sponsored program designed to increase access to quality mental health treatment for employees of a large health care system. Methods: Retrospective data were collected on employer's efforts to develop a programmatic solution to address barriers to accessing quality mental health treatment among its employees and on initial program implementation. Results: Data from the initial cohort ( N = 1049) of program participants support the use of low threshold digital tools to enhance access to care, the importance of care navigation and a robust curated provider network in matching employees to appropriate care options, and the value of providing online, evidence-based psychotherapy to facilitate high rates of treatment engagement. Conclusions: Findings can help inform employers about approaches to improve access to quality mental health treatment for their employees.

RESUMEN

AIMS: To test differential outcomes between three 6-month text-messaging interventions to reduce at-risk drinking in help-seeking adults. DESIGN: A three-arm single-blind randomized controlled trial with 1-, 3-, 6- and 12-month follow-ups. SETTING: United States. A fully remote trial without human contact, with participants recruited primarily via social media outlets. PARTICIPANTS: Seven hundred and twenty-three adults (mean = 39.9 years, standard deviation = 10.0; 62.5% female) seeking to reduce their drinking were allocated to 6 months of baseline 'tailored statically' messaging (TS; n = 240), 'tailored adaptive' messaging (TA; n = 239) or 'drink tracking' messaging (DT; n = 244). INTERVENTIONS: TS consisted of daily text messages to reduce harmful drinking that were tailored to demographics and alcohol use. TA consisted of daily, tailored text messages that were also adapted based on goal achievement and proactive prompts. DT consisted of a weekly assessment for self-reported drinking over the past 7 days. MEASUREMENTS: The primary outcome measure was weekly sum of standard drinks (SSD) at 6-month follow-up. Secondary outcome measures included drinks per drinking day (DDD), number of drinking days (NDD) per week and heavy drinking days (HDD) at 1-, 3-, 6- and 12-month follow-ups. FINDINGS: At 6 months, compared with DT, TA resulted in significant SSD reductions of 16.2 (from 28.7 to 12.5) drinks [adjusted risk ratio (aRR) = 0.80, 95% confidence interval (CI) = 0.71, 0.91] using intent-to-treat analysis. TA also resulted in significant improvements in DDD (aRR = 0.84; 95% CI = 0.77-0.92) and drinking days per week (b = -0.39; 95% CI = -0.67, -0.10), but not HDD compared with DT at 6 months. TA was not significantly different from TS at any time-point, except DDD at 6 months. All groups made improvements in SSD at 12-month follow-up compared with baseline with an average reduction of 12.9 drinks per week across groups. CONCLUSIONS: Automated tailored mobile messaging interventions are scalable solutions that can reduce weekly alcohol consumption in remote help-seeking drinkers over time.

RESUMEN

BACKGROUND: Cognitive behavioral therapy (CBT) is an effective treatment for alcohol use disorder (AUD). We hypothesized that the dorsolateral prefrontal cortex (DLPFC), a region implicated in cognitive control and goal-directed behavior, plays a role in behavior change during CBT by facilitating the regulation of craving (ROC). METHODS: Treatment-seeking participants with AUD (N = 22) underwent functional magnetic resonance imaging (fMRI) scanning both before and after a 12-week, single-arm trial of CBT, using an ROC task that was previously shown to engage the DLPFC. RESULTS: We found that both the percentage of heavy drinking days (PHDD) and the overall self-reported alcohol craving measured during the ROC task were significantly reduced from pre- to post-CBT. However, we did not find significant changes over time in either the ability to regulate craving or regulation-related activity in any brain region. We found a significant 3-way interaction between the effects of cue-induced craving, cue-induced brain activity and timepoint of assessment (pre- or post-CBT) on PHDD in the left DLPFC. Follow-up analysis showed that cue-induced craving was associated with cue-induced activity in the left DLPFC among participants who ceased heavy drinking during CBT, both at pre-CBT and post-CBT timepoints. No such associations were present at either timepoint among participants who continued to drink heavily. CONCLUSIONS: These results suggest that patients in whom DLPFC functioning is more strongly related to cue-induced craving may preferentially respond to CBT.

RESUMEN

PURPOSE: While modifications to alcohol use disorder (AUD) criteria are proposed for DSM-5, examination of the criteria's performance among highly vulnerable populations is lacking. This study determined the dimensionality and rank order severity of the DSM-IV AUD criteria among Temporary Assistance for Needy Families (TANF) recipients with high rates of chemical dependency and co-morbid mental health disorders. METHOD: Secondary analysis was performed on data from 461 TANF eligible women screened for AUD criteria using the Structured Clinical Interview for DSM-IV-TR. Exploratory (EFA) and confirmatory factor analyses (CFA) were performed on the AUD criteria. Two-parameter Item Response Theory (IRT) analysis was performed to determine item location and discrimination of criteria for both abuse and dependence. Differential item functioning for those with an additional substance use disorder or with high levels of depressive symptoms was explored. RESULTS: 41.2% met criteria for dependence, and 4.4% for abuse. EFA and CFA revealed a two-factor model provided adequate fit to criteria, and IRT indicated a potential hierarchical order between the criteria-abuse being more severe but dependence having greater reliability. CONCLUSION: Contrary to existing literature, findings suggest that a two-factor solution may be appropriate. Implications are discussed.

RESUMEN

BACKGROUND: Motivational interviewing (MI) is a widely used intervention applied to a host of health behaviors, including alcohol consumption among individuals with alcohol use disorder (AUD). Age is an underexplored moderator of MI for treating AUD, with the impact of comparing older individuals with their younger counterparts virtually unexplored. Also unexplored is whether age is associated with distinct mechanisms of change (e.g., motivation and self-efficacy) within treatment. METHODS: This secondary data analysis utilizes combined data from two previous studies (total N = 228) that both aimed to test MI's mechanisms of action in the context of a goal for moderated drinking. Both studies had three conditions: MI, nondirective listening (NDL), and a self-change condition (SC). In the current analyses, the moderating impact of continuous age and age group, <51 (younger adults, YA) versus ≥51 (older adults, OA), on the impact of MI on alcohol use compared to NDL and SC were tested using generalized linear models. Age differences in confidence and commitment to reduce heavy drinking during treatment were also explored. RESULTS: Age group by condition differences emerged, where NDL significantly reduced drinking among YA but not OA (mean -12 vs. -3 standard drinks, respectively). Among OA, MI outperformed NDL but not SC, though the effect was weak. Confidence and commitment during treatment were not significantly different across age-by-condition groups. CONCLUSION: Findings underscore the importance of understanding the impact of age on treatment effectiveness, as providing a nondirective intervention for OA with AUD could provide suboptimal treatment. Further research is needed to explore these differential effects.

RESUMEN

Alcohol use disorder (AUD) comprises a continuum of symptoms and associated problems that has led AUD to be a leading cause of morbidity and mortality across the globe. Given the heterogeneity of AUD from mild to severe, consideration is being given to providing a spectrum of interventions that offer goal choice to match this heterogeneity, including helping individuals with AUD to moderate or control their drinking at low-risk levels. Because so much remains unknown about the factors that contribute to successful moderated drinking, we use dynamical systems modeling to identify mechanisms of behavior change. Daily alcohol consumption and daily desire (i.e., craving) are modeled using a system of delayed difference equations. Employing a mixed effects implementation of this system allows us to garner information about these mechanisms at both the population and individual levels. Use of this mixed effects framework first requires a parameter set reduction via identifiability analysis. The model calibration is then performed using Bayesian parameter estimation techniques. Finally, we demonstrate how conducting a parameter sensitivity analysis can assist in identifying optimal targets of intervention at the patient-specific level. This proof-of-concept analysis provides a foundation for future modeling to describe mechanisms of behavior change and determine potential treatment strategies in patients with AUD.

RESUMEN

Background: Quality training is an oft-cited barrier to effective implementation and ongoing delivery of high-quality evidence-based practice (EBP) across fields. This is especially true in the addiction field, but there is little cited evidence for optimal methods to improve EBP in inpatient addiction facilities with minimal resources. Objective: The current paper focuses on evaluating the state of our facility's group CBT manual and clinical training on the manual in a "realistic" (ie, non-RCT, non-grant-funded) inpatient addiction treatment setting. Methods: Five full-time clinicians volunteered to take part in the study (woman = 60%; Mage = 36.20 years). The study involved a mix of semi-structured interviews and surveys designed to measure seven outcomes (barriers, feasibility, useability, appropriateness, acceptability, burden, trialability). Results: Three themes emerged from the data that impacted the group CBT manual: training, timing, and functionality. Addressing these themes allowed for a new, optimal manual and training procedure to be put into place. Conclusion: The current study highlights that under-resourced inpatient addiction facilities can still methodically utilize implementation approaches to study their EBP, namely CBT. Such an approach will ensure that the highest quality care is being delivered to patients and actively addresses known training barriers that prevent proper EBP delivery.

RESUMEN

This study examined the impact of intensive case management (ICM) on decreasing child welfare system involvement in a sample of substance-dependent parenting women who participated in a welfare demonstration study comparing ICM to usual screen-and-refer models employed in welfare settings. Previous research established the effectiveness of ICM in both increasing engagement in substance abuse treatment and in promoting abstinence, and the current study tested whether ICM had downstream impacts on child welfare outcomes not directly targeted by the intervention. The sample included 302 mothers recruited from welfare offices and their 888 minor children. Child welfare outcomes were available from administrative records for four years following study entry and included incident reports and out-of-home child placements. An initial positive effect of ICM was found on child placements, but its impact lessened over time and was likely due to the increased contact with case managers that occurred early in the study. Overall, minimal benefits of ICM were found, suggesting that while ICM was effective in the areas of treatment engagement and abstinence, there were no downstream benefits for child welfare outcomes. Implications of findings in terms of increased need for cross-system collaboration are discussed.
