“…Negative and disorganized speech symptoms both can be enduring (Bowie et al, 2005) and both predict poorer long-term outcomes (Liddle, 1994; Walker, 1995; Fuller et al, 2003). In addition, previous research has consistently found that negative and disorganized speech symptoms are distinct (Andreasen, 1979; Harvey et al, 1992).…”

Previous schizophrenia research suggests poor cognitive control is associated with schizophrenia speech symptoms. However, cognitive control is a broad construct. Two important cognitive control components are poor goal maintenance and poor verbal working memory storage. In the current research, people with schizophrenia (n = 45) performed three cognitive tasks that varied in their goal maintenance and verbal working memory storage demands. Speech symptoms were assessed using clinical rating scales, ratings of disorganized speech from typed transcripts, and self-reported disorganization. Overall, alogia was associated with both goal maintenance and verbal working memory tasks. Objectively rated disorganized speech was associated with poor goal maintenance and with a task that included both goal maintenance and verbal working memory storage demands. In contrast, self-reported disorganization was unrelated to either amount of objectively rated disorganized speech or to cognitive control task performance, instead being associated with negative mood symptoms. Overall, our results suggest that alogia is associated with both poor goal maintenance and poor verbal working memory storage and that disorganized speech is associated with poor goal maintenance. In addition, patients’ own assessment of their disorganization is related to negative mood, but perhaps not to objective disorganized speech or to cognitive control task performance.
