What term describes the use of made-up words by a client with schizophrenia?

The term that describes the use of made-up words by a client with schizophrenia is neologisms. In the context of psychosis, particularly schizophrenia, individuals may create new words or phrases that have specific meaning to them but may not be understood by others. This phenomenon is indicative of disorganized thinking and can reflect underlying cognitive impairment linked to the disorder. Neologisms can also be a way for individuals to express their inner experiences or thoughts that feel unique to them, highlighting the altered thought processes that are often present in schizophrenia.

In contrast, paraphasia refers to the production of incorrect or malformed words, alogia is characterized by poverty of speech or reduction in the amount of speech, and logorrhea involves excessive verbosity or an overwhelming flow of words. Each of these terms represents different aspects of language and communication difficulties often seen in mental health conditions but does not specifically address the creation of new words, which is what makes neologisms the correct answer in this scenario.
