Primary Outcome Measures
NameTimeMethod
Change in BOLD response during an emotion regulation task (fMRI)Change in BOLD response from baseline, compared to BOLD response after stimulation (approximately two weeks later)

BOLD response was measured during an emotion regulation task. The change in BOLD response between sessions is the primary outcome for this study

Secondary Outcome Measures
NameTimeMethod
Change in experienced emotion during an emotion regulation task with Visual Analogue Scales (VAS)Change in experienced emotion from baseline, and after the stimulation session (approximately two weeks later)

Participants were instructed to either 'attend' or 'regulate' their emotion associated with the presented (negatively valenced) pictures. Experienced (or regulated) emotion was assessed with visual analogue scales (VAS).

Change in craving levels [Alcohol Urge Questionnaire (AUQ)]Before and after the emotion regulation task, during both baseline and stimulation session (e.g. 4 time points, sessions were separated by approximately two weeks)

The AUQ was administered in order to assess craving levels. The AUQ consists of eight statements wich are rated on a 7 point likert scale \[0 = Strongly disagree, 6 = Strongly Agree\]
