Loneliness as a function of parent-child and peer relations.

It was hypothesized that those who reportedly did not have a satisfactory relationship with their parents, and those who were not able to establish a meaningful interpersonal relationship with their peers during childhood were more likely to experience loneliness with greater intensity in adulthood. The UCLA Loneliness Scale and a personal data sheet were administered to two groups of subjects independently: 232 Iranian college students (156 males, 76 females) studying in American universities and 305 Iranian students (168 males, 137 females) studying in Iranian universities. The hypothesis were confirmed.
