Multisite trials, in which individuals are randomly assigned to alternative treatment arms within sites, offer an excellent opportunity to estimate the cross-site average effect of treatment assignment (intent to treat or ITT) "and" the amount by which this impact varies across sites. Although both of these statistics are substantively…

Results of assessment with 34 children, 35 adolescents, and 40 undergraduates show that State of Mind (SOM) model ratios varied significantly depending on measurement method and self-versus-other condition, although age did not significantly influence SOM ratios, suggesting that the SOM model set point is applicable to children.

Four objectives are to: (1) narrow the distinction between research and evaluation; (2) extend the scope of triangulation and multimethods; (3) approach the problem concretely with extended data and interpretations; (4) structure the discussion in…

In evaluation, the whole is greater than the sum of the parts when quantitative and qualitative approaches and methods are combined. Some circumstances in which both approaches can be effectively combined are considered, and case studies of two evaluations using multiple methods are presented. (LMO)
