Abstract
This paper presents data on six different clinical definitions (indices) of age of onset for major affective disorders. The inter-rater reliability for each index and the relationships among these indices are discussed. Age of onset for impairment with affective symptoms was found to be a reliable and useful index of early onset. It discriminated between unipolar depressed subjects and both bipolar I and bipolar II subjects.
