TY - JOUR PY - 1982// TI - Program implementation and evaluation results: A reexamination of type III error in a field experiment JO - Evaluation and program planning A1 - Rezmovic, Eva Lantos SP - 111 EP - 118 VL - 5 IS - 2 N2 - This paper reexamines the implementation results obtained from a true experiment in criminal justice. The original analyses found a significant difference in employment outcome between the control group and those experimental clients who received the highest level of treatment. The present analyses attempt to bracket true treatment effects by partitioning both experimental and control groups into treated and untreated subgroups, and by combining data from two independent sources. The original results do not obtain when implementation of the control treatment is also considered in the analysis. Corroborating earlier findings, a positive association was found between magnitude of experimental treatment implementation and employment, but it was unclear that the experimental program was responsible for this relationship. The limitations of the experimental design for disentangling effective components of treatment are discussed. The paper provides an example of the utility of secondary analysis for understanding evaluation results.
