This 24-item questionnaire was developed to assess children’s feelings of loneliness and social dissatisfaction. Assessment of children’s own feelings about their peer relations may be useful in identifying children for participation in intervention programs, such as improving social interaction skills or self-concept. Data on the child’s perspective is also useful in evaluating whether social skill training decreases children’s feelings of loneliness or social dissatisfaction and in determining whether intervention efforts are differentially successful as a function of children’s feelings prior to training. Identify children’s feelings of loneliness may predict later adjustment based on children’s participation in a social network.
