Nearly 2.5 million persons die each year in the United States.¹ For the bereaved, these deaths may be among the most painful and disruptive events they will experience. In this article, we evaluate the growing body of research on complicated grief (CG)—which also has been called prolonged grief, chronic grief, traumatic grief, and pathological grief—with an emphasis on how to identify CG and distinguish it from other adaptive and maladaptive reactions to the loss of a loved one. In addition, we review empirical evidence on treating CG, including psychotherapy, pharmacotherapy, and combined treatment approaches.

The bereavement-specific syndrome we refer to as CG currently is being reviewed for possible inclusion in DSM-5 as an official diagnosis. At press time, proposals for DSM-5 included a bereavement-related adjustment disorder within the new Trauma- and Stressor-Related Disorders category, as well as a provisional diagnosis of CG entitled Persistent Complex Bereavement-Related Disorder, which, upon acceptance, would be listed in Section III.²

What is ‘normal’ grief?

Grief is highly variable across individuals and time and may range from an absence of distress to severe and persistent pain and anguish. There’s no simple definition of “normal grief.” However, as clinicians, it’s necessary to understand the range of usual reactions. We recommend 2 considerations when evaluating grief reactions.

First, be aware that grief encompasses a range of cognitions, emotions, and behaviors. It may range from a relative lack of painful thoughts and emotions to intense and disruptive sadness, loneliness, anger, guilt, intrusive thoughts, difficulty concentrating, preoccupation with loss, social withdrawal, and a sense of being overwhelmed by the loss and its consequences. In the months after a loss, bereaved individuals may look for the deceased in a crowd, speak to them, or even experience auditory or visual hallucinations of the deceased. Nonetheless, positive feelings such as relief, peace, and happiness also are common following a loss.³ Moreover, laughter and smiling when discussing a lost loved one predicts reductions in grief symptoms over time.⁴ Overall, grief research suggests that, far from proceeding along standard and uniform stages,⁵ grief is complex and comprises a broad spectrum of thoughts, feelings, and behaviors that vary within and among individuals.

Second, note that in the absence of complications, grief progresses. For those who experience elevated levels of distress, the pain and disruption of loss initially may feel overwhelming but will subside in intensity over time for most individuals.⁵ This is not to say that an individual will never again feel sadness or longing for the deceased; elements of grief are likely to remain. Although the trajectory of grief symptoms varies among individuals and may progress in fits and starts, over time grief becomes more intermittent, less interfering, and is balanced with a sense of interest and purpose in life.

What is CG?

As research on grief experiences has grown, there’s increasing recognition that a minority of bereaved individuals experience more extreme grief symptoms that cause substantial, persistent distress and impairment despite the passage of many months or years. Shear et al⁶ proposed a set of CG diagnostic criteria (Table) in which a cluster of symptoms of intense and persistent separation distress are defined as core symptoms. Similar to other psychiatric diagnoses, the symptoms must be associated with significant distress or impairment.

Proposed diagnostic criteria for complicated grief

Assessing CG symptoms

Among those with persistent elevated distress, a CG diagnosis must be considered in the context of the individual’s social and cultural environment, time since the loss, and duration of symptoms. The hallmark symptom of CG is separation distress with a focus of cognitive, behavioral, and emotional symptoms on the loss and its consequences. CG is associated with substantial distress, functional impairment, and an increased risk for suicide. See the Box for a case study.

Many individuals with CG remain undiagnosed and untreated for years despite high levels of distress and impairment and high risk for negative consequences such as suicide.⁷ Accordingly, there’s a need for greater CG screening. Clinically useful tools for assessing CG include a brief, 5-item dimensional screening assessment⁶ and the patient-rated Inventory of Complicated Grief.⁸

Distinguishing complicated and uncomplicated grief. Exhibiting CG symptoms in the first several months after a loss does not mean an individual has or will develop CG. Most bereaved adults report painful thoughts and emotions in the weeks and months following the loss, including distressed yearning, waves of intense grief, persistent and intrusive thoughts, images related to the death, somatic distress, and a feeling of being disconnected from others. For most individuals, the intensity of this response diminishes within 6 to 18 months after the loved one’s death.⁵ Although the optimal length of time to wait before establishing a diagnosis remains debatable, the earliest CG should be diagnosed is 6 months after a loss.

It’s common for grief to occasionally rise in intensity for days or weeks. This surge may occur many months or years after the loss, even in people who exhibited relatively little distress or impairment. In particular, anniversaries, holidays, or periods of stress may trigger increased grief intensity. However, these surges typically subside naturally within a short time. Accordingly, CG should be diagnosed only when symptoms persist for >1 month.

CG vs other post-loss disorders. CG, major depressive disorder (MDD), and posttraumatic stress disorder (PTSD) often are comorbid in bereaved adults. Simon et al⁹ found 72% of CG patients in a treatment- seeking sample reported a lifetime history of MDD and 53% reported a lifetime history of PTSD. However, CG can be distinguished from these disorders. In the same study, 25% of CG patients had no other axis I diagnosis.⁹ After accounting for comorbid disorders, researchers associated CG severity with work and social impairment. These findings provide clear evidence for the incremental validity of CG—ie, a CG diagnosis gives clinicians additional information that predicts impairment above and beyond other disorders. However, future research needs to further examine CG and its overlap and differentiation from MDD and PTSD.

Distinguishing CG and MDD. Intense yearning or preoccupation with the deceased is a common symptom of CG but not MDD. In addition, CG symptoms possess intentionality. For example, emotional distress such as sadness and anger are prominent features of both CG and MDD. However, in CG, these symptoms are specific to the loss or circumstances of the loss, whereas in MDD they generally are more nebulous and generalized. Similarly, CG entails proximity seeking related to the deceased, and avoidance of reminders of the deceased, whereas MDD includes a more general social withdrawal and anhedonia.

Distinguishing CG and PTSD. CG and loss-related PTSD are distinguished by the predominant emotions and focus of concern associated with each disorder. The predominant emotion in PTSD is fear, whereas in CG it is sadness and longing. In PTSD, intrusive thoughts and memories associated with the trauma generally are associated with the event itself and produce an ongoing sense of threat.¹⁰ Avoidance in PTSD is intended to reduce this threat feeling. By contrast, in CG, intrusive memories focus on the deceased or the circumstances of the death, and avoidance is aimed at preventing painful reminders of the loss or its permanence. Importantly, both syndromes may be present.

Treating CG

When is treatment indicated? For years, bereavement theorists emphasized the need to work through emotions and memories related to the deceased with particular focus on negative material. However, evidence suggests that universal application of treatment to all bereaved individuals is unhelpful. In a recent meta-analysis, Neimeyer et al¹¹ found that the outcomes of grief therapy applied indiscriminately to all bereaved adults or all members of high-risk populations—such as parents whose child experienced a violent death—were no better than would be expected by the passage of time. In contrast, grief therapy applied only to those who develop elevated and persistent distress (eg, CG) led to greater and more enduring improvement in post-loss distress than was observed in control conditions.

These results suggest that most grieving individuals who do not meet criteria for CG (or other psychiatric disorders) will not require intervention. Those who do seek treatment for grief-related distress in the acute grief period should be assessed for bereavement-related depression, anxiety, and suicidality, and treated or referred to professional or community-based resources for support or counseling as clinically indicated.

Evidence for psychotherapy. For those who meet CG criteria, psychotherapy targeting the specific symptoms of CG is helpful. The evidence is strongest for CG treatment (CGT), a 16-session, manualized psychotherapy developed by M. Katherine Shear, MD.¹² CGT is based on an attachment model and cognitive-behavioral therapy (CBT) principles, and is informed by the dual-process theory proposed by Stroebe et al.¹³ According to this theory, natural healing following loss comprises 2 processes:

• a loss-oriented process in which the patient comes to terms with the loss, and
• a restoration-oriented process in which the patient reinvigorates a sense of purpose and meaning in life without the deceased.

CGT focuses on both processes. To address the former, it includes clinician-guided exercises in which the patient revisits the time of the death and planned activities in which the patient reengages with people, places, or thoughts that remind him or her of the deceased. CGT aims to allow the patient to gain an increased tolerance of the distressing thoughts and emotions associated with the loss so that these thoughts can be processed and the finality of the death and its circumstances can be accepted.

The restoration process is addressed by having patients generate and discuss personal goals and aspirations for the near and distant future, as well as scheduling pleasurable and rewarding events. This is accomplished by having patients imagine what they would want for themselves if their grief was less intense and planning concrete steps to take toward these goals. The restoration-oriented process is addressed concurrent with the loss-oriented process to encourage the oscillation between processes thought to be characteristic of a natural healing process following the loss of a loved one.

Other psychotherapy approaches (eg, support groups) may have a role for some individuals, and future research may suggest alternative approaches to CGT. To date, CGT is the most targeted evidence-based psychotherapy with randomized controlled data supporting its use in CG.

Pharmacotherapy for CG. Early research suggested that antidepressants—in particular tricyclics—may effectively reduce depressive symptoms in bereavement-related depression; their effect on CG symptoms, however, may not be as strong.¹⁴ Research on pharmacologic treatment that targets CG symptoms is developing. Because of the overlap between CG, PTSD, and MDD, researchers have hypothesized that antidepressants may be effective. Two open-label studies reported that the selective serotonin reuptake inhibitor (SSRI) escitalopram may be effective for CG.^15,16 Although a post-hoc comparison of paroxetine and nortriptyline¹⁷ showed significant reduction in CG and depressive symptoms with both agents, effects could not be separated from concomitant psychotherapy. Furthermore, an examination of naturalistic data on combining antidepressants with CGT suggested that antidepressants may improve outcomes for individuals receiving CGT.¹⁸ A multicenter, randomized controlled trial funded by the National Institute of Mental Health is examining the potential efficacy of citalopram, an SSRI, alone or in combination with CGT.¹⁹

The efficacy of benzodiazepines, which commonly are prescribed for bereaved individuals, has not been assessed in CG. However, recent research suggests they may not be useful for medically managing recent grief²⁰ and that their use in the aftermath of a loss may lead to long-term dependence in geriatric patients.²¹
