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 (MO) of CNS properties, 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‐Intensity‐Measure (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 five factors: Emotional Stability, Rhythmicity, Activity/Tempo, Sociability, and Impulsivity versus Impulse Control.
