This paper examines trait arousability (TA), a temperament characteristic, in 47 stable outpatients with schizophrenia and 50 non-psychiatric controls. Self-reported levels of stress were obtained during a negative and positive memory speech task. Levels of TA, and the association of TA scores with reported stress during the speech tasks, were examined both between and within groups. In addition, TA scores were examined in relation to symptom presentation in the patient group. Patients reported higher levels of trait arousability and higher levels of stress than controls. Trait arousability scores were significantly associated with reported stress in one of the speech condition in patients, and with the severity of positive and affective symptoms. These results suggest that temperament characteristics of an individual with schizophrenia may be related to stress responsiveness and symptom presentation.
