Adolescent loneliness assessment.

The aim of the present work was to develop a loneliness scale for adolescents in order to assess their perceptions of the quality of their relationships with parents and peers. The scale was administered to 1,233 Argentine secondary school students, aged 13-16 years. Factor analyses (principal axes, oblimin solution) were conducted. Four factors were obtained, which accounted for 43.13% of the variance: Peer Rejection, Family Deficits and Parent Rejection, Personal Inadequacy, and Significant Separation. The internal consistency assessed through Cronbach's alpha was satisfactory. We believe that this proposal, which aims at evaluating the different processes that cause and are caused by a feeling of loneliness, allows for an integral approach to the issue.
