Bereavement-related depression is excluded from a diagnosis of major depressive episode (MDE) in DSM-IV, unless the syndrome is prolonged or complicated. The objective of this study is to assess the validity of the bereavement exclusion by comparing characteristics of bereavement-related episodes that are excluded from a diagnosis and bereavement-related episodes that qualify for a diagnosis (complicated bereavement) to MDE.
We used data from 2 waves of the National Epidemiologic Survey on Alcohol and Related Conditions (n = 43,093) to compare bereavement-excluded depression and complicated bereavement to MDE with respect to indicators of preexisting risk for psychopathology (antecedent indicators) and indicators of disorder severity measured at baseline and at the study's 3-year follow-up interview (consequent indicators). The primary outcome measure was the Alcohol Use Disorder and Associated Disabilities Interview Schedule-IV.
Compared to individuals with MDE, individuals with bereavement-excluded depression had lower risks of preexisting psychiatric disorders (eg, 0.44 lower odds of social phobia, P = .006), fewer depressive episodes (recurrence rate 0.37 times lower, P < .001), less psychosocial impairment (P < .001), a 0.18 times lower odds of seeking treatment (P < .001), and a lower risk of psychiatric disorders during a 3-year follow-up period. Unexpectedly, this same pattern of differences was observed between individuals with complicated bereavement and MDE.
Despite the presence of a clinically significant depressive episode, bereavement-excluded depression is in many ways less indicative of psychopathology than MDE. However, complicated bereavement was more similar to bereavement-excluded depression than to MDE. We therefore question whether the DSM-IV criteria validly distinguish between nondisordered loss reactions (bereavement-excluded depression), pathological loss reactions (complicated bereavement), and nonloss-related MDE.
在 DSM-IV 中,丧亲相关的抑郁被排除在重性抑郁发作(MDE)的诊断之外,除非综合征持续时间长或复杂。本研究的目的是通过比较符合和不符合丧亲诊断的丧亲相关发作的特征,评估丧亲排除标准的有效性,并将其与 MDE 进行比较。
我们使用了全国酒精相关情况和流行病学调查(n=43093)的 2 个波次的数据,比较了丧亲排除性抑郁和复杂丧亲与 MDE 之间的风险指标(先前存在的精神病理学风险指标和基线及研究 3 年随访时的严重程度指标)。主要结局指标是酒精使用障碍和相关障碍访谈调查 IV 版。
与 MDE 患者相比,丧亲排除性抑郁患者先前存在的精神障碍风险较低(例如,社交恐怖症的可能性低 0.44,P=0.006),抑郁发作次数较少(复发率低 0.37 倍,P<0.001),社会心理功能损害较轻(P<0.001),寻求治疗的可能性低 0.18 倍(P<0.001),在 3 年随访期间患精神障碍的风险较低。出乎意料的是,复杂丧亲与 MDE 患者之间也存在同样的差异模式。
尽管存在临床显著的抑郁发作,但丧亲排除性抑郁在许多方面都不如 MDE 更能提示精神病理学。然而,复杂丧亲与丧亲排除性抑郁更相似,而与 MDE 不相似。因此,我们质疑 DSM-IV 标准是否能有效地将无失调性丧失反应(丧亲排除性抑郁)、病理性丧失反应(复杂丧亲)和非丧失相关的 MDE 区分开来。
