Andreasen, N. (1986). Scale for the assessment of thought, language and communication. Schizophrenia Bulletin, 12(3), 473-482. 

This resource presents a description of the kinds of language dysfluency associated with what used to be called “formal thought disorders.” Andreasen breaks these items down into those she considers “communication disorders” and those she considers “thought and language disorders.” She recommends that, collectively, these problems be characterized as “disorders of thought, language and communication.” Some of these problems are strongly associated with forms of severe mental illness such as schizophrenia, mania, and depression. She provides examples of each, relevant interviewer questions, and a scale for measuring their presence and severity.
