creator Fleischer, Michael advisor Mead, Alan Instructions are an integral part of any exam. The present study examines the effects of instructions to avoid the middle answer on a personality questionnaire. We obtained IRT parameters from participants responding to the 16PF Questionnaire with and without this instruction and used a Monte Carlo simulation based on these parameters. Results indicated that when participants were instructed to avoid the middle response, we observed lower item-total correlations and increased difficulty in setting percentiles. Previous research, implications and limitations of this study are discussed as well.
