PSYCHOMETRIC PROPERTIES OF THE HURT-JOSEPH-COOK SCALES FOR THE MEASUREMENT OF INNOVATIVENESS

The paper reports a psychometric appraisal of the scales for the measu rement of innovativeness devised by Hurt, Joseph and Cook in 1977. A r andom sample of 308 British consumers was used to assess the scales in terms of internal reliability, dimensionality, and discriminant valid ity. While the investigation revealed acceptable levels of reliability and discriminant validity, shortened versions of the inventory propos ed by Hurt and colleagues and by the present authors produced improved reliability coefficients. The expectations of Hurt and colleagues for a unidimensional scale is not supported. (C) 1998 Elsevier Science Lt d. All rights reserved.
