Previous research yielded five factors which comprise the experience o
f loneliness, namely, Emotional distress, Social inadequacy and aliena
tion, Growth and discovery, Interpersonal isolation, and Self-alienati
on. The perceived causes of loneliness were grouped into factors of Pe
rsonal inadequacies, Developmental deficits, Unfulfilling intimate rel
ationships, Relocation and significant separations, and Social margina
lity. Using principal components factor analysis, the relations of per
ceived causes and the various aspects of loneliness were examined for
295 men and 338 women. All five of the perceived causes appeared to co
ntribute to experienced loneliness. While scores on Emotional distress
were strongly related to all five factors of perceived causes, the ot
her four factors were differentially related.
