The Strelau Temperament Inventory-Revised (STI-R): Validity studies

This study examines the construct validity of the revised version of the Strelau Temperament Inventory (STI-R) and the short scale (STI-RS) , which were introduced by Strelau, Angleitner, Bantelmann and Ruch (1990). Hypotheses about the relationship between the content scales of the STI-R, viz. Strength of Excitation (SE), Strength of Inhibition (SI) , and Mobility ( M O ) of CNSproperties, and (a ) other personality/ temperament dimensions referring to the level of arousal, (b) selected temperament inventories, and ( c ) selected personality scales are derived and tested in a total of four samples with altogether 420 Ss. The inventories investigated include, among others, the Eysenck Personality Questionnaire-Revised (EPQ-R), Zuckerman 's Sensation Seeking Scale (SSS), the I. 7 Impulsiveness Questionnaire (I. 7), the Affect-IntensityMeasure (AIM) , the EASI, the Structure of Temperament Questionnaire (STQ) , and the Revised Dimensions of Temperament Survey (DOTS-R). In general, the hypotheses regarding the place of the STI-R in the temperament and personality domain were confirmed. A factor analysis of the STI-R, EASI, and DOTS-R yielded jive factors: Emotional Stability, Rhythmicity, Activity/Tempo, Sociability, and Impulsivity versus Impulse Control.
