METAANALYSIS FOR SINGLE-CASE CONSULTATION OUTCOMES - APPLICATIONS TO RESEARCH AND PRACTICE

The application of meta-analysis holds much appeal for single-case con sultation outcome research. We review a meta-analytic method for using within-study treatment effect sizes in reporting consultation outcome s. The strengths and limitations of traditional group design meta-anal ysis are examined. Various methods for analyzing single-case outcomes are discussed briefly, followed by an examination of the use of meta-a nalysis in single-case reviews across independent studies. Within-stud y meta-analytic results are presented that were derived from treatment s implemented in consultations in natural settings. To conclude the ar ticle, an illustration is offered of a single-case data analysis displ ay that incorporates meta-analytic results along with other indices of treatment outcome. Recommendations are provided for using meta-analyt ic methods to evaluate outcomes of single-case consultation treatment.
