Construct Validity of the Temperament Structure Scales Within the Big Five Framework in Aerospace Selection

Kurzfassung

The Temperament Structure Scales (TSS) are used in the selection of pilots, air traffic controllers, and astronauts at the German Aerospace Center (DLR). As there is evidence for the predictive validity of the TSS, its relationship with the popular Big Five factors as indicators of construct validity is investigated. Two samples comprising either European astronaut candidates (N = 902) or German pilot candidates (N = 249) were used. Analyses show consistent commonalities of several TSS scales with four Big Five factors (Neuroticism, Extraversion, Agreeableness, Conscientiousness). The TSS cover most of the broad Big Five factors and additionally provide a more detailed and suitable profile with unique constructs for the selection of aerospace personnel. The TSS are thus recommended for use without additional personality inventories that measure the broad Big Five factors only.
