Mental Contrasting With Implementation Intentions for Alcohol Use Disorders (MCIIAUD)

Applying Mental Contrasting With Implementation Intentions to Prevent Relapse and Drop-out in Patients With Alcohol Use Disorders

Mental Contrasting (MC) consists of imaging a desired future and comparing it with obstacles of the present reality in order to increase goal commitment when expectations of success are high. The study aims to investigate the effects of a motivational training (Mental Contrasting with Implementation Interventions; MCII) as a therapeutic add-on to standard treatment in inpatients with Alcohol Use Disorders.

Study Overview

• Status: Completed
• Conditions: Alcohol Use Disorder
• Intervention / Treatment: Other: MCII; Other: Treatment as usual

Detailed Description

Today's elaborated therapeutic interventions do not ensure sustainability of therapeutic success in alcohol-dependent patients. Thus, it is to develop and implement new therapeutic methods in order to increase regular treatment termination and continuous abstinence during treatment. Mental Contrasting (MC) consists of imaging a desired future and comparing it with obstacles of the present reality in order to increase goal commitment when expectations of success are high.

In the study, MCII is implemented as an add-on intervention in order to reduce the risk of a relapse during treatment and to decrease drop-outs from treatment in alcohol-dependent inpatients. Therefore, inpatients with alcohol use disorder (AUD) are randomly assigned to one of two groups. The experimental group does receive MCII, the control group an exercise from treatment as usual. In addition, patients undergo brief motivational screenings in form of self-report questionnaires at the beginning and during treatment in order to assess motivational mediation of treatment effects and drinking events. The effect of the MCII training will be examined on primary (drinking during treatment) and secondary outcome variables (early treatment termination, motivational changes after drinking events).

The Primary Outcome is return to drinking during treatment defined as any violation of total abstinence. Drinking is assumed if either a drinking event is reported by the patient or a Breathalyzer tests is positive.

Participants are allocated to the groups using randomisation with emphasis on equal group sizes in control and experimental group. The list of randomisation was generated with the online tool "Research Randomizer".

The investigator's a priori calculation of the required sample size is based on the primary outcome, i.e. return to any drinking during treatment. Given α=0.05 and 1-β=0.80 a one-sided z-test then yields a required sample size of 122 participants, i.e. 61 subjects in the intervention group and 61 subjects in the control group.

All randomized subjects will be included in the analyses, regardless of whether they terminate the study regularly or not. Analyses will be done according to the intention-to-treat method (ITT).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Mental Contrasting with Implementation Intentions (MCII); Mental Contrasting with Implementation Intentions (MCII) combines two methods: Mental Contrasting and Implementation Intentions. Mental Contrasting (MC) consists of imaging a desired future and comparing it with obstacles of the present reality (Oettingen, 2000, 2014; Oettingen, Pak, & Schnetter, 2001) in order to increase goal commitment when expectations of success are high (Gollwitzer, 2014). Implementation Intentions on the other hand specify when, where, and how to strive for a goal in form of an if-then-plan, e.g. "If situation Y is encountered, then I will perform the goal-directed response Z" (Gollwitzer, 2014; Wieber, Thürmer, & Gollwitzer, 2015).	Other: MCII; In this study, the research staff will work through the MCII approach with the participant as an interactive, face-to-face training. The desired future consists of imaging an abstinent life and comparing it with personally relevant obstacles. Afterwards, the most relevant obstacle will be chosen and an if-then-plan will be formed, that refers to this obstacle.
ACTIVE_COMPARATOR: Treatment as usual; The control group receive a control training, which consists of an exercise from treatment as usual. Thus, patients in the control group are supported in their intention for abstinence and in the reappraisal of risk situations and relapse, while no individual motivational strategies are planned or provided	Other: Treatment as usual; The patients in the control group will receive a 2 x 2 contingency table about the disadvantages and advantages of being abstinent and of drinking. In addition, abstinence intentions of patients in the control group will also be supported and risk situations and relapse events since the last trainings will be reappraised, but without the use of MCII.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of participants with return to any drinking	Any drinking as measured by self-report or objective testing	through study completion at end of treatment, an average of 10 weeks
Rate of number of drinking events during treatment	Drinking Events as measured by self-report	through study completion at end of treatment, an average of 10 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of participants with early treatment termination	Treatment Termination without consent between patient and therapist	through study completion at end of treatment, an average of 10 weeks
Rate of general self-efficacy for abstinence	self-efficacy will be assessed on the proposal of Ludwig, Tadayon-Manssuri, Strik, and Moggi (2013) to measure self-efficacy with simply one question ("How confident are you that you will be completely abstinent in 1 year, on a scale from 1 to 10?"). This scale is called "general self-efficacy". Lower scores indicate low self-efficacy and therefore a worse outcome; higher scores indicate a high self-efficacy and consequently a better outcome. We changed this question for different time intervals (e.g. the next fourteen days, until the end of treatment). The subscales are analyzed individually.	through study completion at end of treatment, an average of 10 weeks
Rate of goal commitment for abstinence	Goal commitment will be assessed with the "Commitment to Sobriety Scale" (Kelly & Greene, 2014). It is a brief five-item measure to assess level of client commitment to alcohol and drug use cessation and continued abstinence. Each item is rated on a 6-point Likert scale from strongly disagree (1) to strongly agree (6). Lower scores indicate low commitment to sobriety and therefore a worse outcome; higher scores indicate a high commitment to sobriety and consequently a better outcome. A total score will be computed.	through study completion at end of treatment, an average of 10 weeks
