For centuries, philosophers and physicians have noted the beneficial impact of work for the restoration and maintenance of mental health. This paper reports the findings from a survey in which all the principal components (both providers and consumers in one catchment area) contributed data about the degree to which vocational rehabilitation was integrated into systems of care for the mentally ill. The major repetitive themes found at the interface of each participating sector were: rigidity, isolation, compensatory ad hoc operations, and narrow frames of reference. Vocational and other forms of rehabilitation were accomplished by persistent, energetic personnel inventing ingenious solutions to the roadblocks set up at system interfaces. Their problem-solving techniques pointed to ingredients that might help to integrate treatment and rehabilitation efforts. These key elements were flexibility, collaboration, data-based training, and a unified theoretical framework.
