In recent years, participation in social services has re-emerged as a
solution to many of society's problems throughout the world. The study
described here tries to test empirically the assumption that client p
articipation and community belonging lead to improved output. A random
sample of clients in two models of community centres was chosen. The
first model was activated by client participation and controlled by a
community social worker. The second model was not supervised by a comm
unity worker and did not involve the community centre clients on any l
evel of its activities. The study indicates that there are differences
between participants (Model I) and non-participants (Model II) as to
the community centre outputs. Furthermore, client participation leads
to effectiveness if the client feels a sense of belonging to the commu
nity.
