Abstract

Background: While models of addictive behaviour stress the role of an impairment of response inhibition when drug-dependent individuals are confronted with drug-associated stimuli, results from different studies are conflicting. However, there is a considerable lack of studies that assess the reliability of tasks to assess deficits of response inhibition when drug-associated stimuli are presented. Methods: In the present paper we present results from four different studies in which either a stop-signal task (study 1), a go/no-go task (study 2/3) or a go/no-go shifting task (study 4) with alcohol-related stimuli was administered to alcohol-dependent patients or control participants and split-half and/or test-retest reliability of the different outcome measures calculated. Results: Our results suggest that the go/no-go task and the go/no-go shifting task are more reliable tasks to assess impairment of inhibition in response to alcohol-associated stimuli than to the stop-signal task. Especially the go/no-go shifting task achieves at least acceptable split-half as well as test-retest reliability indices for outcome measure related to the presentation of alcohol-associated stimuli. Nevertheless, for alcohol-dependent patients reliability indices are generally considerably lower than for control participants and thus care should be taken when these tasks are administered to alcohol-dependent patients. Conclusion: Future studies are warranted to enhance our understanding of true effects and random error
