This article presents a conception of spouse drinking control and an approach to assessment and modification to reduce the customary drinking control efforts of spouses of alcohol abusers unmotivated to enter treatment. Modification of the nonalcoholic spouse's customary drinking control is offered as an important early step in helping to prepare him or her to become a positive rehabilitative influence. Based on its use in unilateral family therapy with 68 spouses of uncooperative alcohol abusers, procedural guidelines, criteria for use, and two case examples from a crossover experimental dyad are described. Also presented are clinical results illustrating the success of the program, benefits and conditions relating to its use, and areas of possible application.
