  1. The Developmental Model Of Effective Interventions Tom van Yperen, PhD. Netherlands Youth Institute Utrecht University

  2. Will It Work … Does It Work? • The RCT will not be enough. • The ideal design fits the developmental stage of the treatment program. • Don’t mind the gap: the improvement models of practitioners, managers and researchers are interconnected.

  3. Effects Of Youth Care 2.0 Very large effect | | .80 LargeAverage: .70 | (Most studies .40-.80) .50 Moderate | In practice .20 Small (newestimate: ± .40) | .00 No effect In practice | (acc. Weisz cs: ± .01) -.10 (Sourcea.o.: Kazdin, 1991, Kazdin & Weisz, 1998: Lipsey & Wilson, 1993, 1998; Shadish cs, 2000; Weisz cs, 1992, 1995; Van Yperen, 2005; Carr, 2009)

  4. The Controverse • Academic RCT’s are demanding, suffer from many difficulties, and often lead to low understanding of the effects (Lipsey & Cordray, 2009) • Pracitice-based studies lead to many difficulties in causal infrence (Shadish, Cook & Campbell, 2002)
