[An Ultra-Short Instrument to Assess Sensation Seeking: Psychometric Evaluation of the German Version of the Brief Sensation Seeking Scale (BSSS-4)].

The personality trait of sensation seeking (SS) plays a prominent role in health-related risk behaviors and is associated with psychopathology, emotion regulation, and delinquency. Despite this high relevance, hardly any ultra-short self-report measures optimized for test duration exist for the assessment of SS. An exception is the Brief Sensation Seeking Scale (BSSS-4) consisting of four items, which is gaining international popularity. In this study, the German version of the BSSS-4 was psychometrically evaluated for the first time in a student sample ( N =419). A unidimensional confirmatory measurement model showed adequate goodness of fit and internal consistency was in the satisfactory range (ω=0,73). As first evidence for adequate construct validity and in line with the hypotheses, associations of the BSSS-4 with male gender, self-reported risk-taking, and risk-taking behavior (operationalized via a lottery-based behavioral paradigm) but not with current depression were found. An examination of measurement invariance across men and women using multigroup CFA suggested that partial scalar measurement invariance can be assumed for the BSSS-4, when equality constraints for loadings and intercepts of Item 1 are relaxed. Considering its increasing international use, the German version of the BSSS-4 can be recommended overall: For an ultra-short instrument, it is sufficiently internally consistent and rather suitable for gender comparisons. In this regard, the facet of experience seeking may be problematic in terms of gender-dependent differences in measurement properties. In light of insufficiently rigorous tests of instruments for the assessment of SS, the results of comparisons between women and men may thus be interpreted with caution.
