An evaluation of the Briggs-Nebes modified version of Annett's handedness inventory

The Briggs-Nebes (1975) modified version of Annett's (1967) handedness inventory was administered to 59 female and 51 male undergraduates and 101 nursing students. J-shaped distributions of scores in the dextral direction and significant sex differences such that males were more sinistral than females were found. The inventory was found to be multi-dimensional with up to three factors, power, skill, and rhythm in order of importance. The utility of the modified inventory was supported and recommendations were made concerning the use of subscale or factor scores in addition to overall scores.
