Predictors of drinking and functional outcomes for men and women following inpatient alcohol treatment

Predictors of treatment outcome for individuals with alcohol use disorder with a goal of controlled drinking

BACKGROUND

Research is lacking on predictors of outcome for the treatment of alcohol use disorder (AUD) with a goal of controlled drinking (CD). The aim of the study was to investigate one-year outcomes of an RCT, investigating Behavioral Self-Control Training (BSCT) and Motivational Enhancement Therapy (MET) and predictors of positive outcome for weekly alcohol consumption, CD and symptom reduction in AUD.

METHODS

This study is based on secondary analyses from a randomized controlled trial including 250 individuals with AUD (52% men) recruited from three specialized addiction clinics in Stockholm, Sweden. Linear and logistic mixed regression models were used for outcomes at 52 weeks, and linear and logistic regression models for the predictor analyses.

RESULTS

BSCT was superior to MET for the change between baseline to 52 weeks for the outcome of CD, defined as low-risk drinking below ten standard drinks per week for both genders (p = 0.048). A total of 57% of individuals in BSCT attained a level of CD, as opposed to 43% in MET. Females were significantly better in attaining low-risk drinking levels compared to men. The predictor for obtaining CD and reducing weekly alcohol consumption, was a lower baseline alcohol consumption. Predictors of symptom reduction in AUD were lower baseline level of AUD, and a lower self-rated impaired control over alcohol consumption.

CONCLUSIONS

BSCT was superior to MET in obtaining CD levels, and women were superior to men for the same outcome. The study corroborated baseline consumption levels as an important predictor of outcome in CD treatments. The study contributes with important knowledge on key treatment targets, and knowledge to support and advice patients in planning for treatment with a goal of controlled drinking.

Inpatients in substance use treatment with co-occurring psychiatric disorders: a prospective cohort study of characteristics and relapse predictors

BACKGROUND

The characteristics of substance use disorder (SUD) inpatients with co-occurring psychiatric disorders (COD) have been scantly described in the extant literature. This study investigated psychological, demographic and substance use characteristics in these patients, along with predictors of relapse 3 months post-treatment.

METHODS

Prospective data from a cohort of 611 inpatients were analyzed for demographics, motivation, mental distress, SUD diagnosis, psychiatric diagnoses (ICD-10) and relapse rate at 3 months post-treatment (retention rate = 70%).

RESULTS

Compared to patients without COD (n = 322), those with COD (n = 289) were younger, had higher mental distress, lower education and higher likelihood of no permanent residence. The relapse rate was also higher in patients with COD (39.8%) relative to patients without COD (26.4%) (OR = 1.85, 95% CI: 1.23-2.78). The relapse rate was particularly high for patients with COD who were diagnosed with cannabis use disorder (53.3%). Multivariate analysis revealed that among patients with COD, relapse was more likely for individuals with a cannabis use disorder (OR = 2.31, 95% CI: 1.34-4.00), and less likely for older ages (OR = 0.97, 95% CI: 0.94-1.00), females (OR = 0.56, 95% CI: 0.33-0.98) and for those with higher intrinsic motivation (OR = 0.58, 95% CI: 0.42-0.81).

CONCLUSION

This study showed that among SUD inpatients, those with COD had relatively persistent high levels of mental distress and an increased risk of relapse. Enhanced measures aimed at COD patients' mental health problems during the inpatient stay, along with close and personalized follow-up after discharge from residential SUD treatment may reduce the probability of relapse in this group.

Predicting relapse after alcohol use disorder treatment in a high-risk cohort: The roles of anhedonia and smoking

On average, two-thirds of individuals treated for alcohol use disorder (AUD) relapse within six months. There is a critical need to identify modifiable risk factors associated with relapse that can be addressed during AUD treatment. Candidate factors include mood disorders and cigarette smoking, which frequently co-occur with AUD. We predicted that co-occurrence of mood disorders, cigarette smoking, and other modifiable conditions will predict relapse within six months of AUD treatment. Ninety-five Veterans, 23-91 years old, completed assessments of multiple characteristics including demographic information, co-occurring psychiatric disorders, and medical conditions during residential treatment for AUD. Participants' alcohol consumption was monitored over six months after participation. Logistic regression was used to determine if, mood disorders, cigarette smoking status, alcohol consumption, educational level, and comorbid general medical conditions are associated with relapse after AUD treatment. Sixty-nine percent of Veterans (n = 66) relapsed within six months of study while 31% remained abstinent (n = 29). While education, comorbid general medical conditions, and mood disorder diagnoses were not predictors of relapse, Veterans with greater symptoms of anhedonia, active smokers, and fewer days of abstinence prior to treatment showed significantly greater odds for relapse within six months. Anhedonia and cigarette smoking are modifiable risk factors, and effective treatment of underlying anhedonic symptoms and implementation of smoking cessation concurrent with AUD-focused interventions may decrease risk of relapse.

[Differences in the success rates of inpatient therapy for alcohol and illegal drug abusers. A Replication Study]

INTRODUCTION

Irrespective of the type of psychotherapy used, the abstinence-oriented treatment of drug abusers is less successful than that for alcohol abusers. If, on the other hand, the two groups are parallelized in such a way that the patients are identical with respect to the five characteristics of gender, age, schooling, work situation and partner situation, then there is no difference between the success rates of the drug and alcohol abusers. The aim of this study is to determine whether this result can be replicated in another therapeutic institution.

METHOD

Retrospective field study of 320 abusers of illegal drugs and 320 alcohol abusers who were treated with behaviour therapy. By combining the binary characteristics gender, work situation and age, the drug-dependent patients were divided into 2³=8 groups, and the same number of alcohol abusers were randomly selected for each group. The scheduled period of inpatient treatment was 90 days for the alcohol abusers and 120 days for the drug abusers. Every week the patients had one session of individual psychotherapy and four to five group therapy sessions. According to the indications, the certified behaviour therapists implemented the following interventions including behaviour analysis, relapse prevention, cognitive therapy, self-management and behavioural family therapy. Comparison of the success rates was carried out using the Chi² test, and changes in the psychological findings were tested with one-way variance analysis.

RESULTS

There was no difference between drug and alcohol abusers with respect to the rate of therapy termination according to plan (around 80%). A total of 48% of the drug abusers and 41 % of the alcohol abusers who could be followed up had been continuously abstinent at the one-year catamnesis without a single relapse. There were also no differences between the two groups when it was assumed that the patients who could not be followed up had relapsed. In the case of both the drug and alcohol abusers the abstinence rate was highest in over-29-year-old employed men (57.6%; 48.4%). The abstinence rate was lowest in employed female drug abusers (27.8%) and young, unemployed female drug abusers (0%, n=11).

DISCUSSION

What appears to influence the abstinence rate after inpatient treatment is not only the type of substance consumed but also sociodemographic characteristics. In addition to individually tailored therapy, our results confirm the importance of a highly differentiated presentation of the outcomes of therapy in the specialist literature. An average rate of abstinence (e.g. 30%) is insufficient to evaluate an intervention unless information is also provided about the patients for which the intervention is suitable and those for which it is not. In accordance with the Reproducibility Project, we consider replication studies essential in psychotherapy, even though in practice the considerable methodical requirements can only be partially fulfilled.

Preliminary development of a neuroimaging paradigm to examine neural correlates of relationship conflict

Social stress in the form of conflict between romantic partners is a salient correlate of substance use disorders (SUD), and also plays an integral role in SUD treatment outcomes. Neuroimaging has advanced the study of social stress on SUD etiology, course, and treatment. However, no neuroimaging paradigms have yet been developed to examine neural responses to conflict among romantic couples. In order to fill this gap in the literature, the goal of this exploratory study was to examine the preliminary feasibility of a novel relationship conflict fMRI paradigm. We compared the effects of an auditory relationship conflict versus a neutral cue on functional connectivity in corticolimbic brain regions, and the associations between neural activities and self-report ratings of relationship adjustment, substance use problems, and intimate partner violence. We also explored sex differences in neural correlates of relationship conflict versus neutral cues. Participants demonstrated increased functional connectivity between the amygdala and the prefrontal cortex during the relationship conflict cue compared to the neutral cue. Intimate partner violence was associated with functional connectivity. Sex differences emerged in neural responses to the relationship conflict cue compared to the neutral cue. Collectively, the findings demonstrate preliminary validity of this novel neuroimaging paradigm for couples.

Selbstwirksamkeitserwartung, psychische Belastung und Therapieerfahrung als Prädiktoren der Abstinenz nach stationärer Behandlung – eine Replikationsstudie

Zusammenfassung. Fragestellung: Gestatten die Merkmale „Anzahl vorheriger Entgiftungen“, „Depressivität“ und „Selbstwirksamkeitserwartung, SWE“ eine Prognose der Abstinenz zur Ein-Jahres Katamnese? Methode: Prospektive Replikations-Feldstudie in einer anderen Klinik, in der mittels binärer logistischer Regression und Chi Quadrat Tests Unterschiede in Patienten-Merkmalen zwischen zur Ein-Jahres-Katamnese durchgehend abstinenten (N = 285) vs. rückfällig gewordenen Alkoholabhängigen (N = 274) analysiert wurden. Ergebnisse: Ebenso wie in unserer vorherigen Studie waren Alter, Geschlecht, Schulbildung, Arbeitslosigkeit, Familienstand, Partnersituation, suchtspezifische und psychische Komorbidität prognostisch nicht relevant, Ausnahme Persönlichkeitsstörungen. Wiederum hatten Patienten mit weniger als zwei Entgiftungen und einer hohen SWE die höchste Wahrscheinlichkeit ein Jahr durchgehend abstinent zu leben (82 %). Ebenso bestätigt wurde, dass Verbesserungen in der psychischen Belastung nicht mit Abstinenz korrelieren. Depressivität und vorherige Entwöhnungsbehandlungen wurden nicht als Prädiktoren repliziert. Schlussfolgerungen: Vorherige Entgiftungen, SWE und Persönlichkeitsstörungen könnten für den hier untersuchten Kliniktyp allgemeinverbindliche Prädiktoren sein. Inwiefern der Ausschluss der beiden Prädiktoren Depressivität und vorherige Entwöhnungsbehandlungen eine Folge neu eingeführter Interventionen für Depressive und Therapieerfahrene ist, wäre zu prüfen. Wie in unserer vorherigen Studie gestattet das Regressionsmodell trotz geringer Varianzaufklärung und mittlerer Effektstärken die Ableitung kausaler Hypothesen zur klinikspezifischen Verbesserung der Behandlung. Replikationsstudien sollten ebenso wie die empirische Orientierung ein fester Bestandteil verhaltenstherapeutischer Behandlung sein.

Mediation of time perspectives on inclinations to use alcohol and motivation to change relationship

OBJECTIVES

Trajectories of change accompanying alcohol-specialized care can be affected by numerous variables. Massive urges to drink can substantially hamper personal motivation to change. However, time perspective could also play an indirect role in this association. This research explores whether time perspectives mediates the relationship between inclinations to use or not to use alcohol and patients' motivation to change.

DESIGN

The sample included 150 outpatients in care for their problematic alcohol use. Models of mediation were planned.

RESULTS

At the entry in care, three specific time perspectives, Past Negative, Present Fatalistic, and Future, acted as discrete mediators.

CONCLUSIONS

These findings highlight underlying mechanisms connecting inclinations to use or to avoid the substance and the patient's motivation to change. Time perspective could also be an interesting intervention target in existing alcohol-specialized treatment programs.

Predicting drinking outcomes: Evidence from the United Kingdom Alcohol Treatment Trial (UKATT)

AIMS

To explore client characteristics that predict drinking outcomes using data from the UK Alcohol Treatment Trial (UKATT).

METHODS

Multiple linear regression was used to determine if there were any characteristics, measured before the start of treatment, that could predict drinking outcomes at three and 12months, as measured by percent day abstinent (PDA) and drinks per drinking day (DDD) over the preceding 90days.

RESULTS

Lower baseline DDD score and greater confidence to resist drinking predicted lower DDD at both three and twelve months following entry to treatment. In addition to baseline PDA and having greater confidence to resist heavy drinking, female gender, aiming for abstinence, more satisfaction with family life and a social network that included less support for drinking were predictors of percent days abstinent.

CONCLUSIONS

Overall the strongest and most consistent predictors of outcome were confidence to avoid heavy drinking and social support for drinking. More predictors were identified for percent of days abstinent than for drinks per drinking day. For percent of days abstinent, a number of client characteristics at baseline consistently predicted outcome at both month three and month twelve.

Epidemiological and sociodemographic factors associated with complicated alcohol withdrawal syndrome

OBJECTIVES

To analyse the influence of epidemiological and sociodemographic factors in complicated alcohol withdrawal syndrome (AWS).

MATERIAL AND METHODS

A multicentre, observational prospective study was conducted on consecutively added patients with AWS hospitalised in internal medicine departments. We recorded sociodemographic, epidemiological, clinical and progression data. Complicated AWS was defined as that which progressed with seizures or delirium tremens.

RESULTS

We studied 228 episodes of AWS in 219 patients. The mean age was 54.5 years (SD, 11.5), and 90.8% were men. AWS was the cause for hospitalisation in 39.9% of the patients. Some 27.1% of the cases presented seizures, and 32.4% presented delirium tremens. The daily quantity of alcohol ingested was 17.8 standard drink units (SD, 21.4), with 16.6 years of dependence (SD, 11.3). The pattern of alcohol abuse was regular in 82.8% of the patients. Some 38.4% of the patients were married or had a partner, and 45.6% had children. Some 72.7% of the patients were unemployed or retired. Some 68.5% had only completed primary studies. Some 4.8% consumed cannabis, 5.2% consumed cocaine and 3% consumed opioids. The independent variables related to complicated AWS were consumption of a drug other than alcohol (OR, 5.3; 95% CI 1.5-18.7), low education level (OR, 3.4; 95% CI 1.6-7.3) and hospitalisation for AWS (OR, 2.9; 95% CI 1.5-5.6). The model's receiver operating characteristic area was 0.718 (95% CI 0.643-0.793).

CONCLUSIONS

Concomitant drug abuse and a low educational level could help identify patients at risk of complicated AWS.

Functional outcomes in community-based adults with borderline personality disorder

Many individuals in clinical samples with borderline personality disorder (BPD) experience high levels of functional impairment. However, little is known about the levels of functional impairment experienced by individuals with BPD in the general community. To address this issue, we compared overall and domain-specific (educational/occupational; social; recreational) functioning in a sample of community-based individuals with BPD (n = 164); community-based individuals without BPD (n = 901); and clinically-ascertained individuals with BPD (n = 61). BPD diagnoses and functional outcomes were based on well-accepted, semi-structured interviews. Community-based individuals with BPD were significantly less likely to experience good overall functioning (steady, consistent employment and ≥1 good relationship) compared to community-based individuals without BPD (BPD: 47.4%; Non- BPD: 74.5%; risk difference -27.1%; p < 0.001), even when compared directly to their own non-BPD siblings (risk difference -35.5%; p < 0.001). Community-based individuals with BPD versus those without BPD did not differ significantly on most domain-specific outcomes, but the former group experienced poorer educational/occupational performance and lower quality relationships with parents, partners, and friends. However, community-based individuals with BPD were significantly more likely to experience good overall functioning than clinically-based individuals with BPD (risk difference -35.2%; p < 0.001), with the latter group more likely to experience reduced employment status, very poor quality relationships with partners, and social isolation. In conclusion, community-based individuals with BPD experienced marked functional impairment, especially in the social domain, but were less likely to experience the more extreme occupational and social impairments seen among patients with BPD.

Predicting the onset of hazardous alcohol drinking in primary care: development and validation of a simple risk algorithm

BACKGROUND

Little is known about the risk of progressing to hazardous alcohol use in abstinent or low-risk drinkers.

AIM

To develop and validate a simple brief risk algorithm for the onset of hazardous alcohol drinking (HAD) over 12 months for use in primary care.

DESIGN AND SETTING

Prospective cohort study in 32 health centres from six Spanish provinces, with evaluations at baseline, 6 months, and 12 months.

METHOD

Forty-one risk factors were measured and multilevel logistic regression and inverse probability weighting were used to build the risk algorithm. The outcome was new occurrence of HAD during the study, as measured by the AUDIT.

RESULTS

From the lists of 174 GPs, 3954 adult abstinent or low-risk drinkers were recruited. The 'predictAL-10' risk algorithm included just nine variables (10 questions): province, sex, age, cigarette consumption, perception of financial strain, having ever received treatment for an alcohol problem, childhood sexual abuse, AUDIT-C, and interaction AUDIT-C*Age. The c-index was 0.886 (95% CI = 0.854 to 0.918). The optimal cutoff had a sensitivity of 0.83 and specificity of 0.80. Excluding childhood sexual abuse from the model (the 'predictAL-9'), the c-index was 0.880 (95% CI = 0.847 to 0.913), sensitivity 0.79, and specificity 0.81. There was no statistically significant difference between the c-indexes of predictAL-10 and predictAL-9.

CONCLUSION

The predictAL-10/9 is a simple and internally valid risk algorithm to predict the onset of hazardous alcohol drinking over 12 months in primary care attendees; it is a brief tool that is potentially useful for primary prevention of hazardous alcohol drinking.

Ergebnisorientierte Klassifikation Alkoholabhängiger zu Beginn einer stationären Behandlung

Zusammenfassung. Fragestellung: Gestattet die Kombination von Patienten-Merkmalen eine ergebnisorientierte Klassifikation Alkoholabhängiger? Methode: Naturalistische Feldstudie, in der retrospektiv mittels binärer logistischer Regression Unterschiede in Patienten-Merkmalen zwischen zur Ein-Jahres-Katamnese durchgehend abstinenten (N = 431) vs. rückfällig gewordenen Alkoholabhängigen (N = 382) analysiert wurden. Anhand der identifizierten Prognose-Merkmale wurden vier Klassen gebildet. Getrennt für die vier Klassen wurden mittels geschichteter Chi Quadrat Tests weitere Merkmale auf ihre prognostische Valenz geprüft. Ergebnisse: Mit den beiden stärksten Prognosemerkmalen Therapieerfahrung und Depressivität konnten vier Klassen gebildet werden, die sich in ihren Rückfallquoten (30 bis 65 %) signifikant unterschieden. Die Behandlungsdauer korrelierte nur bei den therapieerfahrenen nicht-depressiven Patienten (N = 239) mit späterer Abstinenz. Nur therapieerfahrene, depressive Patienten (N = 50) hatten bei Vorliegen einer Persönlichkeitsstörung höhere Rückfallquoten. Alter, Geschlecht, Schulbildung, Arbeitslosigkeit, Familienstand, Partnersituation und suchtspezifische Komorbiditäten waren für die gesamte Stichprobe und für die vier Klassen prognostisch nicht relevant. Schlussfolgerungen: Die Validität von Prädiktoren ist abhängig von der prozentualen Verteilung der Patientenmerkmale einer Stichprobe, der Therapie, der Stichprobengröße und der Erfolgsquote. Eine ergebnisorientierte Klassifikation gestattet die Ableitung verbesserter therapeutischer Strategien für hoch rückfallgefährdete Patienten. Verbesserte Therapiepläne werden die ergebnisorientierte Klassifikation im Rahmen des lernenden Kliniksystems verändern, so dass nicht von einer Zeitstabilität und Allgemeingültigkeit der klinikspezifischen Prädiktoren ausgegangen werden kann.

Alcohol-Adapted Anger Management Treatment: A Randomized Controlled Trial of an Innovative Therapy for Alcohol Dependence

A randomized controlled trial for an innovative alcohol-adapted anger management treatment (AM) for outpatient alcohol dependent individuals scoring moderate or above on anger is described. AM treatment outcomes were compared to those of an empirically-supported intervention, Alcoholics Anonymous Facilitation treatment (AAF). Clients in AM, relative to clients in AAF, were hypothesized to have greater improvement in anger and anger-related cognitions and lesser AA involvement during the 6-month follow-up. Anger-related variables were hypothesized to be stronger predictors of improved alcohol outcomes in the AM treatment condition and AA involvement was hypothesized to be a stronger predictor of alcohol outcomes in the AAF treatment group. Seventy-six alcohol dependent men and women were randomly assigned to treatment condition and followed for 6 months after treatment end. Both AM and AAF treatments were followed by significant reductions in heavy drinking days, alcohol consequences, anger, and maladaptive anger-related thoughts and increases in abstinence and self-confidence regarding not drinking to anger-related triggers. Treatment with AAF was associated with greater AA involvement relative to treatment with AM. Changes in anger and AA involvement were predictive of posttreatment alcohol outcomes for both treatments. Change in trait anger was a stronger predictor of posttreatment alcohol consequences for AM than for AAF clients; during-treatment AA meeting attendance was a stronger predictor of posttreatment heavy drinking and alcohol consequences for AAF than for AM clients. Anger-related constructs and drinking triggers should be foci in treatment of alcohol dependence for anger-involved clients.

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.
