Abstract

This article draws on the experience gained from conducting a true experiment in the criminal justice field to discuss practical problems in maintaining the integrity of evaluation studies. Issues revolving around budgeting, randomization, data collectors, interview payments, and evaluation of black box treatments are addressed. While these nontechnical aspects of evaluation can significantly affect the validity and meaningfulness of research results, they are rarely discussed in research reports. The need to communicate both research experience and research methodology is stressed.
