These features are also observed in schizophrenia, bipolar mood disorder, and some anxiety disorders. Further study of these phenomena may provide information about pathophysiological processes putatively shared by some psychiatric and epileptic patients. However, there is no reliable instrument for assessing the presence of psychomotor and psychosensory symptoms in psychiatric patients. We report the development of such an instrument, the Profile of Psychomotor Symptoms (POPS), which includes four subscales (Disturbances of Perception, Affect and Mood, Thought Content, and Behavior) and which assesses the current or historical presence of 41 phenomena often described in patients with psychomotor seizures. Of the 82 items assessed, 75 had a mean weighted kappa greater than 0.6, and 14 of these had a mean weighted kappa greater than 0.9. Thus, the POPS items can be assessed with good reliability and internal consistency. Further studies are needed to refine this instrument, establish its psychometric structure, and determine its validity and usefulness. © Lippincott-Raven Publishers.
