Psychologists have had a long-standing interest in the construct of gr
oup cohesion. Yet, how this construct should be defined and measured r
emains a controversial question. a central issue in the debate concern
s the dimensionality of group cohesion. Recently, some researchers hav
e adopted unidimensional models of this construct, whereas others have
used multidimensional models of the same construct. In this study, th
e structure of the Gross (1957) Cohesiveness Scale, which is perhaps t
he most frequently used measure of group cohesiveness, was examined. B
ased on a critical review of the results of three empirical reports an
d reanalyses of the results of two of these studies it was concluded t
hat Gross' measure is unidimensional.
