The paper concerns the sense of loneliness and social maldjustment. The sense of loneliness, contrary to loneliness itself, results in negative mental and social consequences. The reasons behind the increasing sense of loneliness are social and moral changes, educational helplessness of the family and school, as well as replacing face-to-face interaction with media supported contacts. Personality factors that correlate with the sense of loneliness are neurotism, introversion, helplesseness, lower self- efficacy and lower self-esteem. Increasing sense of loneliness generates depression, suicidal attempts, aggression, multiple risk behaviour, and victimization. Suggested directions for practical action in diagnosis and social theraphy concentrate mainly on creating opportunities for forming satisfactory models of interpersonal relationships.
