Does progressive stage transition mean getting better? A test of the Transtheoretical Model in alcoholism recovery Addiction 102 (10), 1588–1596.
To test two central assumptions of stage movement in the Transtheoretical Model (TTM) vis-à-vis alcoholism recovery: (assumption 1) individuals making a forward transition to the action-oriented stages (i.e. preparation/action) will manifest relatively greater drinking improvements than their counterparts remaining in the pre-action stages (i.e. pre-contemplation, contemplation); and (assumption 2) individuals remaining in the pre-action stages across time will not demonstrate clinically relevant improvement in drinking outcomes.
Our findings challenge not only the criterion validity associated with stage movement in the TTM account of alcoholism recovery, but also recent TTM-based substance abuse treatment approaches which systematically promote forward stage transition as a primary clinical goal and marker of therapeutic success.
