Peer reviewedDillman, Don A.; And Others – New Directions for Program Evaluation, 1984
The empirical effects of adherence of details of the Total Design Method (TDM) approach to the design of mail surveys is discussed, based on the implementation of a common survey in 11 different states. The results suggest that greater adherence results in higher response, especially in the later stages of the TDM. (BW)

Peer reviewedYeaton, William H.; Wortman, Paul M. – New Directions for Program Evaluation, 1984
Solutions to methodological problems in medical technologies research synthesis relating to temporal change, persons receiving treatment, research design, analytic procedures, and threats to validity are presented. These solutions should help with the planning and methodogy for research synthesis in other areas. (BS)

Peer reviewedHedges, Larry V. – New Directions for Program Evaluation, 1984
The adequacy of traditional effect size measures for research synthesis is challenged. Analogues to analysis of variance and multiple regression analysis for effect sizes are presented. The importance of tests for the consistency of effect sizes in interpreting results, and problems in obtaining well-specified models for meta-analysis are…

Peer reviewedFortune, Jim C.; McBee, Janice K. – New Directions for Program Evaluation, 1984
Twenty-nine steps necessary for data file preparation for secondary analysis are discussed. Data base characteristics and planned use vary the complexity of the preparation. Required techniques (file verification, sample verification, file merger, data aggregation, file modification, and variable controls) and seven associated pitfalls are defined…

Peer reviewedBoruch, Robert F. – New Directions for Program Evaluation, 1987
It is difficult to conduct randomized field experiments. In the past decade, the use of alternative randomization plans and incentives has contributed to their operational feasibility; legal, ethical, and professional arguments for experimentation have matured; and expectations have become better aligned with practical constraints that are likely…
