A recently developed program for extensive inpatient grief therapy in groups, administered on a time-limited basis, is outlined, an illustrative case study is described, and empirical assessment of the program's efficacy is provided. During a 3-month stay in a Dutch Health Care Centre, a combined treatment program was offered that integrated behavior and art therapy [so-called Cross-Modality Grief Therapy, (CMGT)]. Assessment (levels of symptomatology on the General Health Questionnaire) was made at pretest, post-test, and follow-up and was compared with levels at comparable time points among participants in a more traditional program. Systematic advantages were found for CMGT. Discussion focuses on the identification of elements within CMGT that were responsible for its effectiveness.
