Social intelligence is a construct that not only appeals to laymen as a rel
evant individual difference but also has shown promising practical applicat
ions. Nevertheless, the use of social intelligence in research and applied
settings has been limited by definitional problems, difficulties in empiric
ally differentiating social intelligence from related constructs, and the c
omplexity of most existing measures of social intelligence. The goal of the
present research was to address some of these obstacles by designing a mul
ti-faceted social intelligence measure that is short and easy to administer
. Three studies were conducted to develop and validate the Tromso Social In
telligence Scale (TSIS). Study I examined professional psychologists' inter
pretations of social intelligence to derive a consensually agreed-upon defi
nition of the construct. In Study 2, a large pool of social intelligence it
ems were tested, and a 3-factor, 21-item scale was identified. In Study 3,
the stability of this measure was confirmed.
