consistencies: Cronbach’s a = .88 for NS, a = .82 for AR, and a = .86
for the total scale. Validity was examined by predicting pathological
gambling and the willingness to try new things or change jobs
(Roth et al., 2014). High correlations between the NISS and these
external criteria support Hammelstein and Roth’s assumption that
the NISS is a valid instrument for measuring sensation seeking.
However this assumption is challenged by the questionable validity
of the AR subscale, which often showed zero-correlations with
related constructs. Furthermore, they compared their instrument
to other well-established sensation seeking measures like the
SSS-V and the AISS (Arnett, 1994). The NISS showed higher correlations
with these external criteria than the SSS-V did and was
not statistically significantly correlated with the age of the
participants.
