There has recently been an emphasis on creating a therapeutic milieu in mental hospitals. Numerous publications reflect this trend (1, 2, 5, 6, 7, 8, 9, 11, 14, 15). In addition, studies on attitudes of nurses and patients and on some of the factors which seem important in creating a favourable ward atmosphere have become commonplace (3, 4, 10, 12, 13, 16, 17).
