Feelings of loneliness among adults with mental disorder

Loneliness can affect people at any time and for some it can be an overwhelming feeling leading to negative thoughts and feelings.
The current study, based on the Adult Psychiatric Morbidity Survey in England, 2007, quantified the association of loneliness
with a range of specific mental disorders and tested whether the relationship was influenced by formal and informal social
participation and perceived social support.

Using a random probability sample design, 7,461 adults were interviewed in a cross-sectional national survey in England in
2007. Common Mental Disorders were assessed using the revised Clinical Interview Schedule; the diagnosis of psychosis was
based on the administration of the Schedules of the Clinical Assessment of Neuropsychiatry, while loneliness was derived from
an item in the Social Functioning Questionnaire.

Feelings of loneliness were more prevalent in women (OR = 1.34, 95 % CI 1.20–1.50, P < 0.001) as well as in those who were single (OR = 2.24, 95 % CI 1.96–2.55, P < 0.001), widowed, divorced or separated (OR = 2.78, 95 % CI 2.38–3.23, P < 0.001), economically inactive (OR = 1.24, 95 % CI 1.11–1.44, P = 0.007), living in rented accommodation (OR = 1.73, 95 % CI 1.53–1.95, P < 0.001) or in debt (OR = 2.47, 95 % CI 2.07–1.50, P < 0.001). Loneliness was associated with all mental disorders, especially depression (OR = 10.85, 95 % CI 7.41–15.94, P < 0.001), phobia (OR = 11.66, 95 % CI 7.01–19.39, P < 0.001) and OCD (OR = 9.78, 95 % CI 5.68–16.86, P < 0.001). Inserting measures of formal and informal social participation and perceived social support into the logistic regression
models did significantly reduce these odds ratios.

Increasing social support and opportunities for social interaction may be less beneficial than other strategies emphasising
the importance of addressing maladaptive social cognition as an intervention for loneliness.
