Responses of 584 high IQ children to the 37 item Revised Children's Manifest Anxiety Scale were submitted to a factor analysis. The five factors that emerged (Physiological, Worry/Oversensitivity, Concentration, Lie 1, and Lie 2) were shown to be highly similar to the factors found with the normative sample. Coefficients of congruence revealed significant correspondence between all factors for the high IQ and normative group. Means and standard deviations for males and females at each age group are also reported, revealing lower levels of anxiety for the high IQ group on all variables. Reliability estimates for each age group on the three subscales of anxiety and for the total Anxiety Scale support the clinical and research use of this new scale in work with high IQ children.Identifying intellectually superior students and providing them with an appropriate education has been an important goal for educators but is presently in another cyclical period of emphasis. However, relatively little research exists concerning the various personality dimensions and affective characteristics of intellectually gifted children or whether these dimensions differ from those of children in other IQ ranges. Furthermore, the instruments commonly used to assess these dimensions have not been investigated adequately regarding validity for high IQ children nor for potential bias in their use with high IQ groups.Popular mythology has held that gifted people, especially those labeled &dquo;genius,&dquo; are particularly emotionally unstable. Although this common stereotype has persisted, the available research tends to refute the view that high IQ children have more personality disorders or emotional disturbance than normal IQ children. Much of the earlier research involved the use of projective testing and teacher ratings to measure emotional disturbance and anxiety levels.
