Because of current health care reforms, quality control, accountabilit
y, and cost-effectiveness have become important issues in the practice
of clinical psychology. It is imperative that practicing clinicians b
egin to evaluate their services to assess whether they demonstrate hig
h quality and cost-effectiveness, as well as a continued commitment to
quality improvement. Deming's (1986) approach to quality control is d
iscussed as a useful strategy for improving effectiveness in the pract
ice of clinical psychology. This approach emphasizes the process of id
entification of the client population, improvements through incrementa
l processes: and evaluation of outcomes. Organizational Behavior Manag
ement (OBM) techniques are also reviewed as useful ways in which to su
pplement and improve on Deming's approach to quality control. Science
and quality control are discussed as being inherently coherent. The sc
ientist-practitioner model dictates that services provided to clients
should be rigorously evaluated. Various procedures for evaluating the
quality of services provided in clinical practice are discussed.
