  1. FINDINGS CUMULATION AND REPORT WRITING LECTURE 8 META ANALYSIS EPSY 642 FALL 2009 Victor L. Willson

  2. Meta-Analysis Report-Writing • Traditional journal approach: -Intro, lit review, methods, results, discussion -References: background, studies in meta analysis* -Tables: effects, SEs, Q’s, mediators, moderators -Figures: Cluster diagrams, funnel plots, graphs of effects by features • Literature review approach: -Thematic or theory focus: what lit exists, what does it say Tabular summarizations of works

  3. Theory section • What is already proposed or known about the outcome • What are the purported major mediators and moderators in the literature to date • What does the literature say about each above? What is the controversy

  4. Purpose of Study • Explain why a meta-analysis will resolve problems in the literature • State what the major outcome(s) to be examined • State the major theoretical predictors to be examined

  5. nsevigny@vpfn.tamu.edu Methods • Sample (or population) of studies • Sources used to find articles • Procedures for cross-referencing • Coding procedure • Coding menu (either as a table or appendix if possible) • Procedures for reliability of coding • Data analysis approach (eg. Lipsey & Wilson)

  6. Results • Descriptives: mean, SD, Q total, funnel plot or other figure of effects (see Lipsey & Wilson, for example) • Design artifacts- do any cause interpretation problems, and if so what did you do about them • Revised descriptives after design issues • Mediators and moderators of substantive interest

  7. Data Tables 1. summary of all articles- may have mean effect size or effects for each construct along with major independent variables 2. Table of Q statistics (may be in Table 1 above also) 3. Table of mediators and moderators 4. Any multiple regression analyses (vw does not recommend generally unless good theory for order of entry of predictors)

  8. Summary/Discussion • Refer to your original discussion of literature and theory • What did you find that resolves problems or differences • What new problems have arisen • What research was missing from your meta analysis? What should people study?
