Open Day, in the form of two half day single session family clinics, has operated weekly in the ACT Child and Adolescent Mental Health Service since April 1993 and over a thousand families have been seen. Clinicians are often resistant to the concept of single sessions and frequently overestimate the amount of assistance that clients feel they require. However in an era of sharply increasing demand for services, selective use of single family sessions for milder problems, screened by a telephone intake process, has value to both families and workers. Telephone follow‐ups of 100 families in 1994 and 70 families in 1996 found that single session family interviews were well accepted by the large majority of families seen. Clinicians see the program as reducing pressure from clients for early attention, enhancing client motivation when seen at crisis times, providing readily available consultation support from peers, increasing learning opportunities and building inter‐disciplinary team work.
