Editor's Notes
The purpose of the current review is to evaluate the existing evidence regarding potential within-session mechanisms of change in MI with alcohol or other drug use disorders. As conceptualized in the present review, a mechanism of change is a variable temporally intervening between assignment to MI treatment and measured substance abuse outcome and at least partially explaining the relationship. The central question we sought to answer in this review was: Which MI constructs and variables appear to be the most promising candidates for mechanisms of change?
Inclusion Criteria Studies were included if they met the following criteria: (1) clients received a therapeutic intervention for problematic alcohol use or any use of illegal substances; (2) the therapeutic intervention was referred to as 杜 otivational interviewing, � 杜 otivational enhancement, � 杜 otivational intervention, � or 澱 rief intervention � (and was described by the authors as being based upon the principles of motivational interviewing); (3) the intervention was delivered individually, and not in a group setting; (4) the potential mechanism was measured either during the intervention or immediately following.
