Self-criticism is a personality trait that has been implicated in a wide range of psychopathologies and developmental arrests. Defined as the tendency to set unrealistically high standards for one's self and to adopt a punitive stance towards the self once these standards are not met, self-criticism is both active and cyclical. Self-critics actively create the social-interpersonal conditions that generate their distress, and their distress itself exacerbates self-criticism. Erosion offers a comprehensive treatment of self-criticism based in philosophy, developmental science, personality and clinical psychology, social theories, and cognitive-affective neuroscience. Professor Golan Shahar expertly summarizes the most recent research on the topic and synthesizes theory, empirical research, and clinical practice guidelines for assessment, prevention, and treatment. The book rests upon three elements that, as Shahar argues, are central to the maintenance of self-critical vulnerability: the importance of a concept of an authentic self or the need to "feel real"; the importance of intentionality and goal-directedness; and the power of interpersonal relationships and cultural context. Shahar argues that exploring these elements requires an integrated clinical approach that incorporates multidimensional assessment and interventions which reconcile science, practice, and policy. The result is a broad and scholarly volume that is useful to practitioners, researchers, and theorists interested in self-criticism.
