... • The effects of an intervention (single interventions and/or a collection of interventions targeting the same outcome) can be estimated through a combination of effect sizes derived from the scientific literature, evaluations of individual strategies, and dose estimates based on reach and strength.

... Throughout its first decade, CHI has had a rigorous evaluation process in place, noted Pamela Schwartz, director of program evaluation at Kaiser Permanente. "We have taken that evaluation very seriously, taking an honest look at what has worked and what hasn't worked and making course corrections along the way -- trying to be brutally honest with ourselves and using the evaluation to improve our investments." Schwartz provided several key lessons learned from the evaluation, with a particular emphasis on the challenges posed by measurement.

... If you can detect small changes, it's over a population, so it's a big deal." Other forms of evaluation also can be valuable. For example, one strategy Schwartz and her colleagues have used is PhotoVoice, which entails giving people cameras and having them take pictures related to barriers to health in their community, and then write captions to describe those barriers and how they can be overcome.

... When a program can be improved, the evaluation should provide information that can lead to revised strategies that enhance impact. The concept of dose is exciting, Schwartz concluded, but it also is a new concept that needs to be further developed and tested.
