Self-Assessment Variables as a Source of Information in the Evaluation of Intervention Programs: A Theoretical and Methodological Framework

The article discusses the incorporation of individuals' assessments regarding the effect of intervention program on themselves as a source of information in commonly used quantitative program evaluation methods. The incorporation of Self-Assessment Variables (SAV) into the evaluation process enables the researcher to utilize the information contained in SAV while utilizing other available sources of information as well (such as administrative data). The analysis is based on the assumption that individuals possess valuable and unique information which they employ before self-selection into a program. The theory of planned behavior is used as a framework for examining different aspects of integrating SAV into program evaluation. The article elaborates on the integration of SAV into the matching method and on the possible advantages of that approach. In addition, the article discusses different aspects of the process of eliciting SAV from individuals. Finally, the article outlines possible directions for future research.
