Sensation Seeking and Eysenck's P-E-N

What is it about?

While Sensation Seeking is a construct which loads on both Extraversion (E) and Psychoticism (P), it is not clear whether Sensation Seeking can be reduced to E and P and whether all of its subfactors necessarily load on the same factor(s). We therefore decided to investigate the relationship among these. The 682 participants comprised a heterogeneous sample. They completed the SSS (Form V) and then the EPQ-R-S (short version of the revised EPQ). Factor analysis of the EPQ-R-S revealed simple structure, with 46 of the 48 items being correctly located on their respective factors. Analysis of the SSS also revealed simple structure, with 31 of the 40 items being correctly located on their respective factors. When the items from the EPQ-R-S and SSS were combined in one analysis, using a 4-factor constraint, we could identify these as follows: The first factor entailing items from 3 SSS scales (ES, Dis and BS) and 2 EPQ scales (L and P), could be referred to as Impulsive Unsocialized Sensation Seeking (P-ImpUSS). The second was identified as N; the third was identified as E; and the fourth as TAS. Thus it is P which loads on P-ImpUSS, with TAS being distinct from the latter.
