The impact of loneliness and social relationship dissatisfaction on clinical and functional outcomes in Dutch mental health service users.

The relationship between reduced social connectedness and mental health outcomes is increasingly acknowledged. Yet, relatively little is known about how two crucial subjective aspects of social disconnectedness - loneliness and social relationship dissatisfaction (SRD) - are related to clinical and functional recovery. This cohort study aimed to investigate the associations of loneliness and SRD with various mental health outcomes among 15,512 outpatients from a Dutch mental health service.
