[Item characteristics that predict response latency in personality measures]

This study assesses some item characteristics that are expected to affect response latencies in the computerized administration of a personality questionnaire. First, some previous empirical results are discussed, and a theoretical framework from which predictions can be made is proposed. Second, the predictions are empirically assessed using two data-sets, one of them based on binary items, and the other one based on graded-response items. Some of the results obtained are new, whereas the remaining agree with previous empirical results. The implications of the present results in applied research, and particularly for the use of latencies, is discussed.
