Abstract
The development and testing of an instrument designed to measure '"psy-chological sense of community" (PSC) is described. A discussion of the historical background of the PSC concept is presented and results of the use of the instrument in three U.S. and Israeli communities are described. Specific attention is given to the relationship of PSC and the variables of community satisfaction and competence as well as to applications of the PSC instrument. Since results suggest that certain manipulable variables may be associated with PSC, and that PSC itself may have the properties of a construct, suggestions for further research, and the potential im-portance of PSC for community development and maintenance are given.
