In the premier issue of Social Work, Preston and Mudd (1956) noted fou
r major obstacles to conducting research on the outcomes of social wor
k practice: (1) the lack of reliable and valid outcome measures, (2) t
he lock of practical research designs, (3) the lack of well-procedural
ized and replicable social work treatments, and (4) the lack of approp
riately trained practitioner-scientists. The post four decades have se
en considerable progress made in each of these areas. An empirical cli
nical science of social work practice is now developing. Scientific an
d practice advances within the profession promoting empirical clinical
practice are being aided by progressive ethical views regarding clien
ts' rights to effective treatment and by evolving reimbursement standa
rds promulgated by managed care companies and third-party vendors.
