Is the quality of life of severe mentally ill patients influenced by the intensity of the care provided, their satisfaction with services and/or the amount of unmet needs? The interrelatedness of these three outcome measures was investigated in a sample of 101 patients dependent on long-term psychiatric care in the Northeast of the Netherlands. Instruments used were the Camberwell Assessment of Needs, the Verona Service Satisfaction Schedule and a health related quality of life instrument, the EuroQoL. Quality of life was unrelated to satisfaction with services but was strongly associated with unmet needs in the area of mental and physical health, and of rehabilitation. Quality of life decreased as needs increased. Needs were also strongly related to diagnosis and cognitive functioning. Furthermore, more intensive care settings were provided as needs increased. Demographic, diagnostic and treatment variables did not explain much extra variance in quality of life. Despite the availability of various services in the region there was a lack of tailor made care which took into account specific unmet needs with regard to information, social contacts, and daily activities.
