Development of Local Program Theory: Using Theory-Oriented Evaluation to Make a Difference

Abstract

The aim of this article is to explicate the local program theory of an adolescent pregnancy and parenting program using a mix of methods. By bracketing these methods, local program theory is developed and subsequently used to distinguish between the validity of program theory and the validity of program implementation. Theory is then used as a tool to construct a model of how the program is supposed to work. This is followed by an assessment of the extent to which the program's theories are actually implemented in the field. The intent of using a mix of methods during this process is to gather an extensive, intensive, and comprehensive view of program case managers' thoughts about their work. Analysis is based on the evaluator's recognition of patterns of meaning that contribute to an enhanced contextual and theoretical understanding of the overall effectiveness of this program.
