Notes
1 Personal recollection, Russell Almond. These were mostly internal ETS presentations and did not have a formal publication date.
2 There are also some differences in the other aspects of evidentiary focus. In particular, there are other causes of fatigue besides depression, giving the first item weak discrimination. Furthermore, depression can be present with our without suicidal thoughts, indicating that the second item may be tapping a different “proficiency” of depression.
