Samples of 106 early, 111 middle, and 113 late adolescents responded t
o the UCLA Loneliness Scale and the VSH Sleep Scale. Statistically sig
nificant correlations showed greater loneliness was associated with gr
eater sleep disturbance in early and middle adolescents but not in lat
e adolescents. Both sleep effectiveness and amount of sleep were not a
ppreciably correlated with loneliness during adolescence.
