Camp research conducted by Extension provides ample empirical evidence that the camp experience contributes to healthy child development. National and state outcomes resources have emerged allowing Extension educators to target youth outcomes at camp. Although the emphasis on outcomes has been important and productive, the time has come to focus not only on specific youth outcomes but also on the antecedents of change. Such a focus would allow Extension to identify specific camp program components that make positive youth outcomes more likely. Extension educators are challenged to consider antecedents of change in future camp research and evaluation projects.
