Objective:
The aim of the study was to determine whether experimental manipulation of sense of control would change moderate drinkers' (N=106) task-specific motivational structure and explicit and implicit determinants of their urge to drink alcohol.
Method:
The effects of various levels of information-enhancement and goal-setting on participants' performance on experimental tasks were assessed. Participants were randomly assigned to a high-sense-of-control, low-sense-of-control, or no-intervention group. Dependent measures were indices derived from a task-specific version of the Personal Concerns Inventory and the Shapiro Control Inventory, Alcohol Urge Questionnaire, and alcohol Stroop test.
Results:
At baseline, there were no differences among the groups on any of the measures; however, post-experimentally, induced sense of control had led to increases in adaptive motivation and decreases in explicit and implicit measures of the urge to drink.
Conclusions:
The results show that sense of control can be experimentally induced. This finding has important clinical implications.
