Abstract: | We investigated the effects of information about validity scales on the Personality Assessment Inventory (PAI) on underreporting of symptoms in a college student population. A group of participants completing the PAI under the standard instructions was compared to two groups of participants who had been instructed and given incentives to underreport symptoms. One of the underreporting groups was given a brief warning about the presence of scales designed to detect respondents attempting to present an unrealistically favorable impression. Results suggested that underreporting scales on the PAI are effective in discriminating standard profiles from those completed by uncoached underreporting participants but are less effective in discriminating standard profiles from those produced by participants who have been warned about the underreporting scales. The findings suggest that coaching may enable some respondents to underreport symptoms without detection. |
