The clinical importance of subtypes based on enduring deficit or negative symptoms was examined in a group of schizophrenic patients who were assessed twice over a 1-year period. Subgroups of patients with high levels of enduring negative or deficit symptoms, based on the Scale for the Assessment of Negative Symptoms and the Quality of Life Scale, had a poorer prognosis and were consistently worse in social adjustment, quality of life, and thought disorder over the year than were patients with less severe negative symptoms. Subtypes based on Andreasen's negative schizophrenia classification and on enduring thought disorder were only weakly related to other symptoms and social adjustment. Social-skill deficits were weakly related to the enduring negative symptom subtype and Andreasen's negative schizophrenia. The results suggest that enduring negative and deficit symptoms may be associated with a poor outcome in schizophrenia, including more severe positive symptoms, lower levels of social adjustment, and a poorer quality of life.
Previous research on social skills training has demonstrated its usefulness as an adjunct treatment for a variety of psychiatric disorders. At the Medical College of Pennsylvania at Eastern Pennsylvania Psychiatric Institute, an acute-care psychiatric hospital, a social skills training group has been in operation for over 3 years. The group is unique in its format in several ways that are described in this article. Data collected over the 3-year period are also presented. The major findings indicate that even over a very brief period of time during an acute hospitalization, patients can learn basic conflict resolution skills. Some predictors of skill acquisition were also identified.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
