A field study was conducted to examine if time of adoption (i.e., purchase innovativeness) was systematically related with use innovativeness, product involvement, and extent of product usage. The results showed that early adopters had significantly higher use innovativeness and product involvement as compared to the early majority. Although usage variety was higher for early adopters, no significant differences were found in usage frequency between the two groups. Use innovativeness and involvement mediated the relationship between purchase innovativeness and usage variety. © 1994 John Wiley & Sons, Inc.
