Work/home conflict is a dominant stress for workers in industrialized countries, particularly in dual-employment families. Interindividual (husband/wife) and interrole (work/home) conflicts in such families are a unique source of stress and adversely affect family and marital relationships as well as performance at work. Neither family therapy nor the stress literature have reported any interventions directed specifically at reducing work/home conflicts in employed couples or parents, although many workplaces today offer stress prevention programs aimed at individual workers. This paper discusses the underlying theoretical rationale for a marital enhancement intervention currently being developed for prevention of distress associated with work/home conflicts. The program combines marital enrichment and training principles with stress management techniques and aims at reinforcing shared coping resources. It focuses on four main variables associated with interpersonal processes: unrealistic expectations based on irrational beliefs, social undermining, shared decision control, and social support.
