The purposes of this study were to determine the dimensionality of the
revised UCLA Loneliness Scale for adolescents through factor-analytic
techniques, and to provide construct validity for the instrument by t
esting four theoretically derived hypotheses in 333 adolescents, ages
12 to 21. Using a prior criteria, a two-factor structure, resulting fr
om a principal components analysis with an orthogonal rotation, best r
epresented the dimensionality of the instrument for adolescents. The t
wo factors demonstrated acceptable coefficient alpha reliabilities. Ev
idence of construct validity for the total scale was provided by three
statistically significant correlations found be264tween the scale and
the theoretically relevant variables of future time perspective, clos
e friend solidarity, and dependency. Contrary to expectation, slow tem
po was not appreciably related to loneliness. The results support the
use of the revised UCLA Loneliness Scale in future research concerning
loneliness in adolescents. (C) 1995 John Wiley and Sons, Inc.
