 Early work on psychological sense of community was based on neighborhoods as the referent, and found a relationship between psychological sense of community and greater participation (Hunter, 1975; Wandersman & Giamartino, 1980), perceived safety (Doolittle & McDonald, 1978), ability to function competently in the community (Glynn, 1981), social bonding (Riger & Lavrakas, 1981), social fabric (strengths of interpersonal relationship) (Ahlbrandt & Cunningham, 1979), greater sense of purpose and perceived control (Bachrach & Zautra, 1985), and greater civic contributions (charitable contributions and civic involvement) (Davidson & Cotter, 1986).These initial studies lacked a clearly articulated conceptual framework, however, and none of the measures developed were based on a theoretical definition of psychological sense of community.McMillan & Chavis's (1986) theory (and instrument) are the most broadly validated and widely utilized in this area in the psychological literature.
