This article presents a model for conceptualizing psychopathology designed to assist practitioners in evaluating patients and applying effective treatment plans. The model describes psychopathology as a function of (a) level of ego organization and (b) character style. Two adjunctive variables are discussed that augment treatment planning through (a) evaluation of the individual's current level of adaptive functioning and (b) confirmation of the diagnostic conceptualization and treatment approach by evaluation of the primary dynamic or conflict. These 2 major dimensions and 2 adjunctive variables are examined in relation to theoretical description of psychological functioning and procedures for assessment and treatment considerations, respectively. Key guidelines for the treatment of prototypical disorders are presented.
