Parallel short forms for the Boston Naming Test: psychometric properties and norms for older adults

Four 15-item and two 30-item short forms for the Boston Naming Test were validated using 108 non-neurological community-dwelling adults, ages 57-85. All forms were administered to all participants (counterbalanced), with no effect of administration sequence on any score. An age effect emerged (Multiple R = .28, p< or =.01). No effects for education or gender were found, nor were there any interactions (p> or = .10). Descriptive data are stratified by age group. Reliability and validity for each form were demonstrated in several ways. These short forms should be very useful as screening instruments and/or as alternate forms for the BNT in test-retest clinical protocols, pre-post experimental designs, and longitudinal research.
