Effective disease prevention and health promotion to address the public health challenges facing Australia
requires a strong evidence base for policy and practice. Evaluation of programs in natural contexts is a vital
source of this evidence, valuable for improving strategy design and delivery, building sustainability and
guiding funding. The aim of this study is to determine the strengths and limitations of evaluation by health
promotion agencies, and to identify the roles of individual, organisational and system -level factors in relation
to evaluation practice and use. This knowledge will guide efforts to build capacity for evaluation, improve
systems for organisational learning, and enable evidence gathering to improve effectiveness.
