The Perceived Deficits Questionnaire (PDQ)

Over the past two decades, Dr. Sullivan and his colleagues have been involved in a program of research examining how perceived cognitive deficits impact of physical and psychological function in individuals with debilitating health and mental health conditions. The Perceived Deficits Questionnaire (PDQ) was developed as part of this program of research. The PDQ assesses the degree to which individuals with debilitating health or mental health conditions experience problems with memory, attention or concentration. Research has shown that perceived cognitive deficits are common in individuals with persistent pain conditions such as whiplash, and mental health conditions such as depression. High scores on the PDQ have been associated with more prolonged and pronounced disability.

The PDQ is now licensed and distributed by Mapi Research Trust on behalf of Dr. Michael Sullivan.
