Minnesota Multiphasic Personality Inventory profiles were analysed in 55 patients with pseudoseizures (40 patients with pseudoseizures only-pure group, and 15 patients with both pseudoseizures and epilepsy-mixed group). For each of the 10 clinical scales, there were no significant differences between the groups in mean T-score values or the incidence of pathological scores (T-score of 70 or above). In 87.3% of cases in the entire sample (groups combined), at least one clinical scale was elevated in the pathological range. For the combined groups, scales having the highest mean values as well as highest incidence of pathological scores were Schizophrenia, Hysteria and Depression. The mean profile of the entire sample (n = 55) had a two-point code of 8-3 with Schizophrenia and Hysteria as profile peaks. Application of three sets of published criteria for hysteria or conversion yielded markedly different results. This finding underscores the difficulty in evaluating the role of hysteria in pseudoseizures in the absence of a single standard. Mean values and the overall profile of this patient sample were remarkably similar to those found in two previous studies.
