RAMALHO, Glória. Utilização de modelos lineares em designs pré-teste e pós-teste - Grupo único e experimental versus controlo . Aná. Psicológica [online]. 1997, vol.15, n.1, pp.5-17. ISSN 0870-8231.

There is currently a large number of approaches to formulate and analyze research problems. One of such approaches, General Linear Statistical Models, is an effective and powerful answer to many of these problems. In this paper we present an overview of this approach´s rational and two examples of its aplication, both involving repeated measures: i) one group pre-test-posttest design; ii) experimental versus control group pretest-posttest design.

Palabras clave : Repeated measures; Linear models; Pretest-posttest designs.
