Purpose: loneliness in adults increases with age. Although loneliness has been found to be associated with psychiatric disorders and dementia, no information is available on prevalence of loneliness in older psychiatric patients. Given the negative consequences of loneliness for morbidity and mortality, identification of specific populations vulnerable to loneliness is important. The aims of the present research were to examine prevalence of loneliness in older psychiatric outpatients, including gender differences and associations with psychiatric disorders and with social situation.

interviews were done in 181 patients from an outpatient clinic for geriatric psychiatry between September 2013 and February 2018, using questionnaires regarding loneliness, depression, anxiety, frailty and alcohol use.

prevalence of loneliness was as high as 80%. Loneliness was associated with having less social contacts, in women only. There were no associations with DSM-IV-TR-classifications. However, loneliness was associated with higher scores on a depression questionnaire. There were no significant differences in intensity of treatment between lonely and non-lonely participants.

Loneliness is highly prevalent in older psychiatric outpatients, with men and women equally affected. Loneliness should be assessed in all older psychiatric patients, especially when they show high scores on symptom checklists or have a restricted social network.

Loneliness and social isolation have negative health consequences and are associated with depression. Personality characteristics are important when studying persons at risk for loneliness and social isolation. The objective of this study was to clarify the association between personality factors, loneliness and social network, taking into account diagnosis of depression, partner status and gender.

Cross-sectional data of an ongoing prospective cohort study, the Netherlands Study of Depression in Older Persons (NESDO), were used.

474 participants were recruited from mental health care institutions and general practitioners in five different regions in the Netherlands.

NEO-Five Factor Inventory (NEO-FFI) personality factors and loneliness and social network were measured as well as possible confounders. Multinominal logistic regression analyses were performed to analyse the associations between NEO-FFI factors and loneliness and social network. Interaction terms were investigated for depression, partner status and gender.

Higher neuroticism and lower extraversion in women and lower agreeableness in both men and women were associated with loneliness but not with social network size irrespective of the presence of depression. In the non-depressed group only, lower openness was associated with loneliness. Interaction terms with partner status were not significant.

Personality factors are associated with loneliness especially in women. In men lower agreeableness contributes to higher loneliness. In non-depressed men and women, lower openness is associated with loneliness. Personality factors are not associated with social network size.

Poor recovery from depressive disorder has been shown to be related to low perceived social support and loneliness, but not to social network size or frequency of social interactions. Some studies suggest that the significance of social relationships for depression course may be greater in younger than in older patients, and may differ between men and women. None of the studies examined to what extent the different aspects of social relationships have unique or overlapping predictive values for depression course. It is the aim of the present study to examine the differential predictive values of social network characteristics, social support and loneliness for the course of depressive disorder, and to test whether these predictive associations are modified by gender or age.

Two naturalistic cohort studies with the same design and overlapping instruments were combined to obtain a study sample of 1474 patients with a major depressive disorder, of whom 1181 (80.1%) could be studied over a 2-year period. Social relational variables were assessed at baseline. Two aspects of depression course were studied: remission at 2-year follow-up and change in depression severity over the follow-up period. By means of logistic regression and random coefficient analysis, the individual and combined predictive values of the different social relational variables for depression course were studied, controlling for potential confounders and checking for effect modification by age (below 60 v. 60 years or older) and gender.

Multiple aspects of the social network, social support and loneliness were related to depression course, independent of potential confounders – including depression severity – but when combined, their predictive values were found to overlap to a large extent. Only the social network characteristic of living in a larger household, the social support characteristic of few negative experiences with the support from a partner or close friend, and limited feelings of loneliness proved to have unique predictive value for a favourable course of depression. Little evidence was found for effect modification by gender or age.

If depressed persons experience difficulties in their social relationships, this may impede their recovery. Special attention for interpersonal problems, social isolation and feelings of loneliness seems warranted in depression treatment and relapse prevention. It will be of great interest to test whether social relational interventions can contribute to better recovery and relapse prevention of depressive disorder.
