More than meets the eye: how examiner training affects the reliability of the MacNeill-Lichtenberg decision tree in geriatric rehabilitation patients.

Objective: To examine the effect of examiner training on the test-retest reliability of the MacNeill-Lichtenberg Decision Tree (MLDT), a tool for guiding clinicians' decision making for referrals for mental health problems.

Design: Correlational analyses and chi-squares were used to examine the influence of demographic variables on MLDT performance and the test-retest reliability of its cognitive and affective components.

Setting: Rehabilitation unit of a large, freestanding, urban hospital.
