The suicide of a related person can often induce severe negative emotional reactions. The objective of this study was to explore the relationships between sociodemographic and diagnostic data of suicides and survivors’ emotions and to close this substantial gap. The main outcome of this study was that survivors’ severity of emotional disturbance was inversely correlated with age of suicides. In the multivariable approach, only age remained related to the majority of the assessed survivors’ emotions, whereas other characteristics, such as gender, presence of psychiatric disorder, or suicide method were not associated with survivors’ emotions. Age had a dominant impact on the relationship between suicides’ characteristics and survivors’ emotional reactions and supersedes the effect of most suicides’ characteristics including diagnoses.
