Therapeutic success in relapse prevention in alcohol use disorder : the role of treatment motivation and drinking-related treatment goals
This is an Accepted Manuscript of an article published by Taylor & Francis in Journal of Addictive Diseases on 5. Nov 2020, available online: http://www.tandfonline.com/10.1080/10550887.2020.1820810Background
Changing addictive behavior is a complex process with high demands on motivation. The Transtheoretical Model of Behavior Change provides a theoretical framework for explaining and predicting behavioral change, although its predictive value for addiction is somewhat inconsistent.
Objective
The aim of the present study is to extend the Transtheoretical Model of Behavior Change by investigating not only treatment motivation but also the predictive value of the type of drinking-related treatment goal. Additional predictors, such as substance-related and sociodemographic variables, are also included in analyses seeking to predict return to drinking during relapse prevention treatment for alcohol use disorder.
Methods
In this observational study, 99 inpatients from a treatment center for alcohol use disorder were recruited. Treatment motivation was assessed in accordance with the Transtheoretical Model of Behavior Change, drinking-related treatment goal through a self-report questionnaire, and substance-related and sociodemographic variables via the clinic information system. Associations between the potential predictors and covariates were explored using stepwise logistic regression.
Results
During treatment, 42.6% of participants had at least one relapse. Scoring higher on the action dimension at admission (OR = 0.81, p = .04) and being employed (OR = 0.37, p = .02) were significant predictors of abstinence during treatment.
Conclusions
This study confirms that treatment motivation contributes to the prediction of treatment outcome, even when controlling for other variables. In future research, the underlying mechanisms of treatment motivation should be further explored
Decision- and feedback-related brain potentials reveal risk processing mechanisms in patients with alcohol use disorder
Individuals with alcohol use disorder (AUD) are aware of the risks of alcohol abuse
yet continue risky drinking. Research indicates that dysfunctional decision processes
and trait variables such as impulsivity contribute to this awarenessâbehavior
discrepancy. The present study focused on decisionârelated versus feedbackârelated
processes as potential contributors to decision making in AUD by examining the
relationship between decision choices and decisionâ and feedbackârelated ERP phenomena
in the balloon analogue risk task (BART). N = 39 AUD and n = 35 healthy
comparison participants (HC) performed the BART modified for EEG assessment.
In each of 100 runs, participants made a series of choices about whether to pump
up a virtual balloon, which popped pseudorandomly, ending the run. Alternatively,
participants ended the run by pressing a âcashâoutâ button. Each pump not producing
a pop provided .05 âŹ; popping resulted in loss of the runâs accumulated gain.
Groups made similar choices, though AUD responded more slowly. The decision P3
200â400 ms after decision prompt (balloon) was larger in AUD than in HC, and decision
P3 enhancement on highârisk trials predicted choices to pump. Feedbackârelated
negativity (FRN) after loss (relative to cash out) feedback was smaller in AUD than
in HC, suggesting indifference to negative feedback. In AUD, high impulsivity was
associated with riskâmodulated decision P3 but not FRN. Results indicate atypical
decisionâ and feedbackârelated processes that could contribute to difficulties in engaging
with daily challenges effectively.publishe
Therapieerfolg bei der RĂŒckfallprĂ€vention bei AlkoholabhĂ€ngigkeit : die Rolle der Behandlungsmotivation und der trinkbezogenen Behandlungsziele
Einleitung: Die Ănderung von Suchtverhalten ist ein komplexer Prozess mit hohen Anforderungen an die Motivation. Das Transtheoretische Modell der VerhaltensĂ€nderung bietet einen theoretischen Rahmen fĂŒr die ErklĂ€rung und Vorhersage von VerhaltensĂ€nderungen, obwohl sein Vorhersagewert fĂŒr Sucht etwas uneinheitlich ist.
Zielsetzung: Ziel der vorliegenden Studie ist es, das Transtheoretische Modell der VerhaltensĂ€nderung zu erweitern, indem nicht nur die Behandlungsmotivation, sondern auch der Vorhersagewert der Art des trinkbezogenen Behandlungsziels untersucht wird. ZusĂ€tzliche PrĂ€diktoren, wie substanzbezogene und soziodemografische Variablen, werden ebenfalls in die Analysen zur Vorhersage der RĂŒckkehr zum Alkoholkonsum wĂ€hrend der RĂŒckfallprĂ€ventionsbehandlung bei Alkoholkonsumstörung einbezogen.
Methoden: In dieser Beobachtungsstudie wurden 99 stationĂ€re Patienten aus einem Behandlungszentrum fĂŒr AlkoholabhĂ€ngigkeit rekrutiert. Die Behandlungsmotivation wurde anhand des Transtheoretischen Modells der VerhaltensĂ€nderung, die trinkbezogenen Behandlungsziele anhand eines Selbstauskunftsbogens und die substanzbezogenen und soziodemografischen Variablen anhand des Klinikinformationssystems bewertet. Die ZusammenhĂ€nge zwischen den potenziellen PrĂ€diktoren und Kovariaten wurden mithilfe einer schrittweisen logistischen Regression untersucht.
Resultate: WĂ€hrend der Behandlung hatten 42,6 % der Teilnehmer mindestens einen RĂŒckfall. Eine höhere Bewertung der Handlungsdimension bei der Aufnahme (OR = 0,81, p = .04) und eine BerufstĂ€tigkeit (OR = 0,37, p = .02) waren signifikante PrĂ€diktoren fĂŒr die Abstinenz wĂ€hrend der Behandlung.
Schlussfolgerungen: Diese Studie bestĂ€tigt, dass die Behandlungsmotivation zur Vorhersage des Behandlungsergebnisses beitrĂ€gt, selbst wenn andere Variablen kontrolliert werden. In kĂŒnftigen Forschungsarbeiten sollten die der Behandlungsmotivation zugrunde liegenden Mechanismen weiter erforscht werden
