Abstract The purpose of this study was to examine the relationship of self-concept and future orientation to loneliness in a group of pregnant teenagers. Pregnant teenagers attending public health clinics for prenatal care were asked to participate in the study. Subjects completed the Revised UCLA Loneliness Scale, the Heimberg Future Time Perspective Inventory, and the Tennessee Self-Concept Scale. Data analysis revealed a significant negative correlation between self-concept and loneliness and a significant negative correlation between future time perspective and loneliness. Stepwise multiple regression analysis indicated that self-concept and future time perspective together explained 38 percent of the variance in loneliness. The findings revealed that self-concept was the best predictor of loneliness in this sample and that the prediction of loneliness was strengthened in the presence of a weak future time perspective.
