Using the Lonliness and Social Dissatisfaction Questionnaire (Asher & Wheeler, 1985), significant differences were found for loneliness and social dissatisfaction among four groups of adolescents based on class placement and rank within placement. Results indicated that general education students were significantly less lonely than special day class students. In addition, the low-achieving group of adolescents was significantly lonelier and socially dissatisfied than the high-achieving group. Research must now focus on effective interventions for specific groups of adolescents who are at higher risk for feelings of loneliness and social dissatisfaction.
