The role of the in-patient community meeting is discussed in relation to the general difficulty of attributing specific effectiveness to any type of therapeutic activity on an in-patient service. Close scrutiny of such units demonstrates that staff and patients are composed of several heterogeneous subgroups, not all of whom share common attitudes and values or benefit from similar activities. Within this framework the major problems as well as functions of the community meeting are discussed. Specific questions which await investigation with clinical research are elaborated.One of the present legacies of the evolution of the therapeutic communities of the 1950s into the therapeutic milieus of the 1960s and beyond is the large-group or community meeting as an integral part of psychiatric ward structure and functioning. The community meeting has persisted over two decades despite major changes in philosophy and focus of in-patient psychiatry, changes characterized by greatly decreased lengths of stay, a relative return to a more sophisticated medical model, and greater emphasis on crisis intervention and use of medication as well as decreased emphasis on insight-oriented therapies. Common sense, clinical experience and research studies converge in the opinion that ward atmosphere, milieu activities and the overall ' therapeutic' experience for patients are correlated in some meaningful fashion, although the close linkage of specific milieu activities to therapeutic outcome is hard to demonstrate (Hall & Pill, 1975). Studies have been more successful in relating milieu difficulties to detrimental patient care (Stanton
