Determinants of loneliness of young adult drug users.

Loneliness is a subjective experience that is influenced by such variables as personality, life experiences, and situation. In the present study, the author examined the connection between the use of ecstasy (MDMA) and the antecedents of loneliness. MDMA users were compared with non-MDMA drug users and with a group of young adults in the general population who did not use drugs. A total of 818 participants from all 3 groups volunteered to answer a 30-item yes-no questionnaire reflecting on their experiences of loneliness and what caused them. Results showed that the predominant causes of loneliness were personal inadequacies, developmental deficits, unfulfilling intimate relationships, relocation or significant separations, and social marginality. There were significant differences between the scores of the MDMA users and scores of the other groups. Gender differences between and within groups were also examined.
