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 less than or equal to.01). No effects for education or gender were found, nor were there any interactions (p greater than or equal to.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.
