— Negative symptoms have been assessed in 34 cases of major endogenous depression (RDC) using the Scale for Assessment of Negative Symptoms. Correlation coeffecients between negative symptoms and improvement rated on a 5‐point scale were determined. Poverty of speech, affective flattening and avolition ‐apathy were found to be related with poor outcome. There was also a negative relationship between improvement and certain frequently occurring negative sym‐toms: inability to feel emotions, feelings of emptiness in thinking and feeling of avolition. High total negative symptom scores predicted poor outcome.
