Abstract:Introduction. In recent years, an increase in research concerning cognitive behavioural modification (CBM) in relation to alcohol use disorders could be observed. This can be explained by the fact that CBM represents a potential cost-effective addition to regular therapy (CBT) by addressing the unconscious and automatic approach tendencies related to alcohol. Therefore, this study discusses the effect of cognitive bias modification (CBM) in form of an approach avoidance training (AAT), as adjustment to therapy as usual (TAU). Moreover, this study focusses on the level of adherence, as the intervention is conducted in an outpatient treatment setting. Methods. This study involved a double-blind randomized placebo-controlled trial in an outpatient context. Patients received therapy as usual (CBT), as well as CBM alcohol avoidance training or a placebo training. In total, the study involved 139 participants. A two-way mixed ANOVA with repeated measurements was conducted to compare pre- and post-assessments, whereas the level of alcohol consumption was taken as outcome measure. Results. The results of the current study did not show a significant effect of AAT. However, participants in both groups showed a decreased alcohol consumption. There was a significant difference between adherent and non-adherent participants, whereof the latter showed a higher reduction in alcohol consumption compared to adherent participants. However, as the sample size was quite unequal, results must be regarded with caution. Discussion. The current results show that CBM does not have additional value to regular therapy, since both groups consumed less alcohol after going through AAT. Controversially, non-adherent participants manifest better treatment outcomes than adherent participants. However, further research needs to be investigated in order to draw an evidence-based conclusion.
