Phenomenology, psychopathology, biology, genet­ ics, pharmacological and nonpharmacological treatment, psychosocial and longitudinal research: all have found a new focus of interest. This volume attempts to provide an unbiased picture of the status of American and Eu­ ropean knowledge regarding the positive\/negative distinction. Researchers from North America and Europe describe the relation of modern concepts of positive and negative symptomatology to the original models of Rey­ nolds and Jackson. Integrating phenomenological, genetic, and biological factors, the authors depict current methods of assessing positive and nega­ tive symptomatology, differentiating between primary and secondary symp­ tomatology, and using pharmacological and nonpharmacological treatment. The stability of positive and negative symptoms over time and evidence for the occurrence of separate positive and negative episodes over a long-term course of schizophrenia are extensively discussed in terms of their implica­ tions on the positive\/negative construct. The relevance of the positive\/nega­ tive dichotomy to child and adolescent schizophrenia is also debated. The main aim of this book is not to advocate a single concept and present only arguments supporting it, but to discuss important controversies. Prob­ lems concerning a concept cannot be solved by ignoring them. However, unanswered questions may be resolved through discussion, debate, and con­ structive compromise.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783642768439\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783642768439","offer_id":39444622770269,"sku":"9783642768439","price":106.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/4557c333-cae4-415b-b76f-2b16985f0b8e.jpg?v=1762062872","url":"https:\/\/shop.autorenwelt.de\/en\/products\/negative-versus-positive-schizophrenia-von-nancy-c-andreasen-andreas-marneros-ming-t-tsuang-hrsg","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
