†Observations are all the original (first) rating. Excludes retested duplicated observations.
^#Interviewer 1 was the field supervisor for the AAH neighborhood rating phase.
⁺Krause scale scores range from 5–20 (Range for this test was 5–16); AAH 7-item Scale scores range from 0–17 (Range for this test was 0–13) and for the AAH 5-item Scale scores range from 0–11 (Range for this test was 0–9).
