Bereaved people suffer from loneliness and loneliness is associated with poor mental health. In this study, this topic is reviewed. An agenda is suggested for future research. Research that is theory-driven, addresses measurement consistency, correlates of loneliness in bereaved and non-bereaved, and treatment is necessary for prevention and intervention.

Objective
to examine the hypothesis that PTSD with delayed expression in some cases occur without subthreshold PTSD symptoms above background levels bridging the gap between the traumatic exposure(s) and the clinical diagnosis.

Objective: The Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, Text Revision includes prolonged grief disorder as a novel disorder. Prolonged grief disorder can be diagnosed when acute grief stays distressing and disabling, beyond 12 months following bereavement. Evidence indicates that elevated prolonged grief disorder symptoms in the first year of bereavement predict pervasive grief later in time; targeting early elevated grief may potentially prevent symptoms getting chronic.

Background: This study tested the hypotheses that (i) the relationship between a history of childhood abuse and severity of psychosis is mediated by loneliness; (ii) the relationship between loneliness and psychosis is mediated by within-person fluctuations in depressive and anxious feelings. Methods: Fifty-nine individuals with non-affective psychotic disorder rated the intensity of loneliness, positive symptoms, and depressive and anxious feelings during repeated moments in daily life (Experience Sampling Method).
