Complicated grief: A systematic review of prevalence, diagnosis, risk and protective factors in the adult population of spain.

Abstract

The main objective of this research was to review the status of the psychopathological research of complicated grief in adult population of Spain, specifically the prevalence and risk factors. A systematic review of PsycINFO, PsycArticles, PTSDpubs, and PSICODOC databases identi-fied 12 studies in which, overall, 1.627 adults had been evaluated. The results of this review show that there is no consensus about the diagnosis of complicated grief, the use of detection instruments, or the risk and protective factors for complicated grief. The weighted mean prevalence based on 6 of the reviewed studies was 21.53%. Taking into account the type of grief measurement used, a prevalence of 7.67 – 10.68% was obtained in those studies that used diagnostic instruments, and 28.77% in those using symptomatic instruments. The results indicate that complicated grief is related to: a lower socioeconomic level and unfavorable work situation, the loss of a child or spouse, younger age of the deceased, previous psychological vulnerability, the use of psychotropic medication, and comorbidity with other disorders. Social support, palliative care, problem-centered coping strategies, the use of pleasant activities, and transcendence or spirituali-ty are shown as protective factors.
