先前的研究表明,十个自然失去亲人的个体中有一个会发展为长期悲伤障碍(PGD)。关于非自然死亡后PGD的患病率知之甚少,比如事故,灾难,自杀,或者杀人.这项研究的目的是计算PGD的合并患病率,并确定其各种估计的可能原因。
在PsycINFO中进行了文献检索,OvidMedline,飞行员,Embase,WebofScience,和CINAHL。使用随机效应模型进行荟萃分析以计算PGD的合并患病率。采用多变量荟萃回归分析研究间的异质性。
25篇文章符合资格标准。随机效应汇总患病率为49%,95%CI[33.6,65.4]。独生子女的死亡,暴力杀戮和非西方研究地点与较高的PGD患病率相关。损失和自然灾害损失的时间较长与PGD患病率较低有关。
这些发现应谨慎解释,由于研究方法的异质性。
首次对不自然损失后的PGD进行荟萃分析,表明近一半的丧亲成年人经历过PGD。这说明了在受损失和创伤影响的个体中评估PGD的重要性。
Previous research has indicated that one out of ten naturally bereaved individuals develops prolonged grief disorder (
PGD). Less is known about the prevalence of
PGD following unnatural deaths, such as accidents, disasters, suicides, or homicides. The aim of this study was to compute the pooled prevalence of
PGD and to determine possible causes of its varied estimates.
A literature search was conducted in PsycINFO, Ovid Medline, PILOTS, Embase, Web of Science, and CINAHL. A meta-analysis using random effects models was performed to calculate the pooled prevalence rate of PGD. Multivariate meta-regression was used to explore heterogeneity among the studies.
Twenty-five articles met eligibility criteria. The random-effects pooled prevalence was 49%, 95% CI [33.6, 65.4]. Death of only child, violent killings and non-western study location were associated with a higher PGD prevalence. A longer time since loss and a loss in a natural disaster were associated with a lower PGD prevalence.
These findings should be interpreted with caution, because of the heterogeneity in study methodology.
This first meta-analysis of PGD following unnatural losses indicated that nearly half of the bereaved adults experienced
PGD. This illustrates the importance of assessing
PGD in individuals affected by loss and trauma.
