Loneliness in relation to suicide ideation and parasuicide: a population-wide study

Suicide Life Threat Behav. 2001 Spring;31(1):32-40. doi: 10.1521/suli.


Some links between loneliness and different manifestations of suicidal conduct have been reported in variety of subgroups (e.g., college students, the elderly, psychiatric patients). We tested this hypothesis by using the results of a population-wide survey. Strong associations among suicide ideation, parasuicide and different ways of being lonely and alone, defined either subjectively (i.e., the feeling), or objectively (i.e., living alone or being without friends), were observed. Moreover, prevalence of suicide ideation and parasuicide increased with the degree of loneliness. Only minimal differences between men and women were found.
