The experience of basic emotions in schizophrenia with and without affective negative symptoms.
A diminished ability to experience emotion could be a key characteristic of the negative symptomatology in schizophrenia. We examined the frequency of basic emotions in everyday life as well as emotion control in various groups of chronic schizophrenic patients. Self-report questionnaires (Differential Emotions Scale [DES], Emotion Control Questionnaire [ECQ]) were provided to healthy controls and three groups of schizophrenia patients (n=88), i.e., affectively flat patients, anhedonic patients, and patients not suffering from affective negative symptoms. Patients with affective negative symptoms experienced the positive emotions interest and joy less frequently than healthy subjects or patients without affective negative symptoms. All schizophrenia patients felt fear more often and tended to feel disgust more frequently than healthy subjects. The frequency of guilt and anger experiences increased with the chronicity of the disease. Anhedonic patients manifested more emotion inhibition than healthy controls and exhibited an affectivity pattern consistent with Meehl's model of anhedonia.
