UMI films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer. The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction. In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand comer and continuing from left to right in equal sections with small overlaps.

Treatment requires allocation o f limited resources for optimal impact. Responsible decision making in this area should be based upon reasoned weighing o f research evidence. Miller and colleagues completed a meta-analytic review of all controlled studies published before 1992 to help clinicians do just that. The coding system they employed examined methodological quality, as well as outcome, to obtain a rank ordering o f treatments that seem to have the most quality research support. The current study attempts to extend this work utilizing the same coding on studies published since 1992, and combine both databases of articles. Revised rank orderings o f treatments and conclusions regarding variables related to outcomes are reported. Implications are discussed, along with limitations of this review. An upward trend in methodological quality over time was also discovered. (144 pages) ACKNOWLEDGMENTS I would like to thank David Stein for his guidance and patience working with me on this project. Further, I would like to thank Susan Crowley and Carolyn Barcus for their participation on my committee, their helpful suggestions, and their occasional questions/reminders regarding my progress toward completion. I would also like to thank Karen Ranson for her hard work in helping to format and prepare this document. Lastly, I want to thank my wife for tolerating me on those nights when it felt as though I would never finish. I could not have done it without you.
