title: The time is now for action research.
abstract: Despite highly systematic methods for identifying priority problems and assessing intervention effects, the recent study by Tourgeman-Bashkin and colleagues would not be considered rigorous by conventional standards of validity, nor would its sample size of three units impress policymakers eager to promote large-scale change through improvement programs. Yet, study findings suggest that no single intervention would have accomplished as much as the action research approach the authors' employed. This perspective argues that although action research may lend itself to neither clean comparisons of intervention and control units over time nor far-reaching improvement campaigns, its advantages, including responsiveness to context, emphasis on implementation and sustainability, and insight about underlying mechanisms of change, make rigorous action research a highly attractive alternative for engendering real world improvement.
