| Abstract: | Several studies have shown that the symptoms of grief are different from symptoms of depression among bereaved family members. This study is an attempt to replicate this finding among advanced cancer patients and examine clinical correlates of patient grief and depression. Analyses were conducted on data from interviews with 123 advanced cancer patients. Grief was measured using symptoms from the patient version of the Inventory of Complicated Grief-Revised (ICG-R) and symptoms of depression were assessed using the Structured Clinical Interview for DSM-IV (SCID). A factor analysis revealed that symptoms of patient grief formed a coherent factor that was distinct from a depression factor. Patient grief "caseness" (defined as being in the top 10% of the distribution of grief scores), but not major depressive disorder, was uniquely associated with the wish to die (odds ratio [OR] 10.13 [0.1.08-95.06]). Both depression and grief were significantly associated with mental health service use (OR 16.07 [1.68, 153.77] vs. 4.82; CI = [1.09, 21.41]) and negative religious coping (OR 1.36 [1.06, 1.73] vs. 1.25 [1.05, 1.49]); neither was associated with terminal illness acknowledgement.

They have also shown that independent of symptoms of depression, severe and prolonged symptoms of grief are associated with mental and physical impairments such as an elevated risk of suicidal ideation and attempts, hypertension, cardiac events, functional impairments, hospitalization, adverse health behaviors, and reduced quality of life (Horowitz et al., [<reflink idref="bib20" id="ref8">20</reflink>]; Latham &amp; Prigerson, [<reflink idref="bib28" id="ref9">28</reflink>]; Ogrodniczuk et al., [<reflink idref="bib30" id="ref10">30</reflink>]; Ott, [<reflink idref="bib31" id="ref11">31</reflink>]; Prigerson et al., [<reflink idref="bib39" id="ref12">39</reflink>]; Prigerson et al., [<reflink idref="bib37" id="ref13">37</reflink>]; Prigerson et al., [<reflink idref="bib36" id="ref14">36</reflink>]; Prigerson et al., [<reflink idref="bib41" id="ref15">41</reflink>]; Simon et al., [<reflink idref="bib47" id="ref16">47</reflink>]). Prolonged grief can be distinguished from normal grief by the severity and duration of symptoms and the marked distress and disability with which symptoms of prolonged grief disorder (PGD), but not normal manifestations of grief, are associated (Prigerson et al., [<reflink idref="bib38" id="ref17">38</reflink>]; Prigerson &amp; Jacobs, [<reflink idref="bib40" id="ref18">40</reflink>]; Prigerson, Vanderwerker, &amp; Maciejewski, [<reflink idref="bib42" id="ref19">42</reflink>]). Consensus criteria for PGD in bereaved individuals have been proposed for the <emph>Diagnostic and Statistical Manual of Mental Disorders</emph>, 5th edition (<emph>DSM-V</emph>; Prigerson et al., [<reflink idref="bib42" id="ref20">42</reflink>]), but these symptom criteria have not been evaluated in patients with terminal illness. Patients who are dying cope with multiple losses including the loss of health, independence, function, role, and the future loss of relationships, all of which may be sources of grief. We sought to determine whether grief over such losses formed a cluster of symptoms distinguishable from those of depression.</p> <p>The diagnosis of depression in advanced cancer patients is often difficult to distinguish from grief and other forms of mental distress, as well as from symptoms associated with physical illness (Green &amp; Austin, [<reflink idref="bib17" id="ref21">17</reflink>]) and its treatment (Besisik, Kocabey, &amp; Caliskan, [<reflink idref="bib2" id="ref22">2</reflink>]; Geinitz et al., [<reflink idref="bib16" id="ref23">16</reflink>]; Ito et al., [<reflink idref="bib21" id="ref24">21</reflink>]). For example, the neurovegetative symptoms of depression (poor appetite, loss of energy, difficulty sleeping, and diminished concentration) can be confused with the symptoms of terminal illness. Similarly, withdrawal from persons other than close family is often thought of as a symptom of depression, but in the setting of terminal illness, this behavior can be a normal part of the grieving process (Block, [<reflink idref="bib3" id="ref25">3</reflink>]). Although grief shares some additional characteristics with depression such as an association with somatic distress, there are some important differences. Freud had postulated that self-esteem, self-loathing and suicidality would be associated with depression but not grief (Freud, 1917/1989), whereas we find identity confusion and decrements in one's perceived self-worth are symptoms of PGD (Prigerson et al., [<reflink idref="bib42" id="ref26">42</reflink>]) and that post-loss grief is a strong predictor of suicidality (Latham &amp; Prigerson, [<reflink idref="bib28" id="ref27">28</reflink>]; Szanto et al., [<reflink idref="bib49" id="ref28">49</reflink>]). The aim of this study was to examine the distinction between depressive and grief symptoms in terminally ill cancer patients.</p> <p>The gold standard for diagnosing depression at the end of life is the clinical interview (Koenig, Cohen, Blazer, Meador, &amp; Westlund, [<reflink idref="bib26" id="ref29">26</reflink>]). However, since the usual diagnostic features of depression do not apply, experts suggest assessing for alternative clinical indicators such as hopelessness, helplessness, intractable pain, excessive somatic preoccupation, disproportionate disability, poor cooperation or refusal of treatment, and hopelessness or aversion on the part of the clinician (Block, [<reflink idref="bib3" id="ref30">3</reflink>]). Endicott has recommended that the <emph>DSM-IV</emph> major depressive disorder (MDD) criteria be modified so that neurovegetative symptoms of depression are substituted with psychological symptoms (Endicott, [<reflink idref="bib13" id="ref31">13</reflink>]).</p> <p>As cancer patients approach the end of life, the relief of mental suffering assumes heightened importance as a goal of cancer care. Providing appropriate treatment for psychological distress rests on clarity about diagnosis, thus differentiating symptoms of depression from those of grief will enhance efforts to provide specialized care. In this study, we set out to determine whether symptoms of grief are distinct from those of MDD in a cohort of advanced cancer patients who had metastatic disease and had not responded to first-line chemotherapy and who would die a median of 4 months from the baseline assessment.</p> <hd id="AN0048207671-2">Method</hd> <p></p> <hd id="AN0048207671-3">Sample</hd> <p>Patients were recruited from August 1, 2002, to April 25, 2007, as part of an ongoing multi-site longitudinal investigation (MH63892, CA106370) of advanced cancer patients and their primary, informal (unpaid) caregivers called the Coping with Cancer (CWC) study. Participating sites included the Yale Cancer Center (New Haven, CT), the Veterans Affairs Connecticut Healthcare System Comprehensive Cancer Clinics (West Haven, CT), Memorial Sloan-Kettering Cancer Center (New York, NY), Simmons Comprehensive Cancer Center (Dallas, TX), and the Parkland Hospital Palliative Care Service (Dallas, TX). Approval was obtained from the human subjects committees of all participating centers; all enrolled patients provided written informed consent. Inclusion criteria were (a) diagnosis of advanced cancer (presence of distant metastases and failure of first-line chemotherapy); (b) diagnosis at a participating site; (c) age greater than 20 years; (d) identified unpaid, informal caregiver; and (e) adequate stamina to complete the interview. Patient–caregiver dyads in which either the patient or caregiver met criteria for dementia or delirium (by neuro-behavioral cognitive status exam) or did not speak either English or Spanish were excluded. Potentially eligible patients were identified by oncology staff at each site. Research staff approached each identified patient to offer participation in the study. Once the patient's written informed consent was obtained, medical records and clinicians were consulted to confirm eligibility.</p> <p>The most common reasons for nonparticipation included "not interested" (<emph>n</emph> = 113), "caregiver refuses" (<emph>n</emph> = 33), and "too upset" (<emph>n</emph> = 27). Non-participants reported more distress (<emph>M</emph> = 2.84; <emph>SD</emph> = 1.31) than participants (<emph>M</emph> = 2.42; <emph>SD</emph> = 1.27; <emph>t</emph> = 3.92, <emph>df</emph> = 652, <emph>p</emph> value &lt;.0001) on a 5-point Likert scale whose extremes ranged from 1 (<emph>minimal/nonexistent</emph>) to 5 (<emph>distraught</emph>). They did not differ significantly from participants by age, gender, race, or education.</p> <p>Of the 998 contacted patients, 810 were eligible for inclusion into the study. Of these, 123 (12.3%) had complete information on a modified version of the rater-administered Inventory of Complicated Grief—Revised (ICG–R; Prigerson &amp; Jacobs, [<reflink idref="bib40" id="ref32">40</reflink>]), the refinements of which were added later in the course of the study. Compared to the other study participants, the 123 particpants included in the analyses were younger (<emph>M</emph> = 56.1, <emph>SD</emph> = 11.90 vs. <emph>M</emph> = 59.0, <emph>SD</emph> = 12.40; <emph>t</emph> = 2.35, <emph>df</emph> = 591, <emph>p</emph> = 0.02); had fewer years of formal education (<emph>M</emph> = 12.1, <emph>SD</emph> = 4.13 vs. <emph>M</emph> = 13.1, <emph>SD</emph> = 4.11 years; <emph>t</emph> = 2.38, <emph>df</emph> = 591, <emph>p</emph> = 0.02); and were less likely to be White (59.35% vs. 72.25%; <emph>df</emph> = 1, χ<sups>2</sups> statistic = 7.67, <emph>p</emph> = 0.006). However, they did not differ from the remaining participants in gender or rates of MDD.</p> <hd id="AN0048207671-4">Measures</hd> <p>The ICG–R is used for the diagnosis of Complicated Grief in bereaved particpants, now called PGD (Prigerson et al., [<reflink idref="bib42" id="ref33">42</reflink>]), and consists of 25 symptom criteria assessed at 0–12 months post-loss. Prior work using Item Response Theory (IRT) and Differential Item Functioning analysis (DIF; Prigerson et al., [<reflink idref="bib42" id="ref34">42</reflink>]) suggests that 13 of the 25 items are biased or contribute little information compared to the most informative symptoms. These items (Prigerson et al., [<reflink idref="bib42" id="ref35">42</reflink>]) and the symptom duration criterion were eliminated given the multiple losses and difficulty in dating the index loss in the context of terminal cancer. The 12 unbiased, informative ICG–R symptoms were modified so that the loss referred to the patient's illness (i.e., loss of health and normal function) rather than the surviving caregiver's grief.

complete information on the items from the SCID Axis 1 Modules for MDD (Keller et al., [<reflink idref="bib24" id="ref36">24</reflink>]) and Endicott criteria for MDD (Endicott, [<reflink idref="bib13" id="ref37">13</reflink>]). The SCID has high test–retest reliability for these lifetime diagnoses, with an overall weighted Kappa of 0.68 (Williams et al., [<reflink idref="bib50" id="ref38">50</reflink>]). The Endicott criteria substitute biologic depressive symptoms likely to be confounded with cancer with four cognitive and emotional symptoms items. Using the Endicott criteria, weight loss was substituted with depressed appearance, insomnia was substituted with social withdrawal or decreased talkativeness, loss of energy was substituted with brooding, self-pity, or pessimism, and poor concentration was substituted with lack of reactivity/can't be cheered up.</p> <p>Other clinical correlates were examined because of their expected association with patient emotional distress. The Yale Evaluation of Suicidality scale was used to measure patient wish to live and wish to die. This scale has been found to be a useful measure of suicidality in bereaved participants (Ogrodniczuk et al., [<reflink idref="bib30" id="ref39">30</reflink>]). Religious coping, assessed with Pargament's Brief RCope (BRC) has shown to account for significant unique variance in measures of adjustment (stress-related growth, religious outcome, physical health, mental health, and emotional distress) after controlling for the effects of demographics and global religious measures (Koenig, Pargament, &amp; Nielsen, [<reflink idref="bib27" id="ref40">27</reflink>]; Pargament et al., [<reflink idref="bib33" id="ref41">33</reflink>]; Pargament, Koenig, &amp; Perez, [<reflink idref="bib32" id="ref42">32</reflink>]). We hypothesized that patients with lower levels of religious coping would have higher grief scores. We also hypothesized that higher grief scores would be correlated with terminal illness acknowledgement. Terminal illness acknowledgment was assessed by a question that asks patients to define their health status as "relatively healthy," "seriously ill but not terminal," or "seriously ill and terminal" whereby only those who endorse the latter are considered to acknowledge their terminal illness (Prigerson, [<reflink idref="bib35" id="ref43">35</reflink>]; Ray et al., [<reflink idref="bib43" id="ref44">43</reflink>]). Mental health service use was assessed with the question, "Have you accessed any type of mental health intervention to help you adjust to your illness since you were diagnosed with cancer?"</p> <p>An exploratory factor analysis was performed to examine the number of underlying constructs that exist with the proposed patient items for PGD and the <emph>DSM-IV</emph> depression items for MDD. Once the scree plot identified the number of main factors, the analyses were rerun to determine the factor loadings when the analyses were restricted to the main factors. Fisher's exact test was used because of the small cells in the analysis of the association between patient grief "caseness" and depression defined by the SCID axis 1 Modules for MDD and the Endicott substitution criteria for depressive disorder. Logistic regression analyses regressed binary outcomes (MDD, PGD "caseness") on clinical correlates, controlling for demographic variables of patients' age, gender, education and race. Patient grief "caseness" was determined by dichotomizing a summary grief symptom severity score at the top 10% of scores. Ten percent was chosen to be comparable to the prevalence of MDD in the full sample of the CWC, which is 7.41% (Kadan-Lottick, Vanderwerker, Block, Zhang, &amp; Prigerson, [<reflink idref="bib23" id="ref45">23</reflink>]), and because this percentile corresponds to the rate of PGD in community samples of the bereaved (Barry, Kasl, &amp; Prigerson, [<reflink idref="bib1" id="ref46">1</reflink>]).</p> <hd id="AN0048207671-5">Results</hd> <p>The factor analysis revealed two distinct symptom clusters: one, a depression cluster, comprised entirely of SCID MDD items, and the other a patient grief symptom cluster (Table 1). The eigenvalues for Factor 1 (MDD) and Factor 2 (patient grief symptoms) were 5.22 and 4.88, respectively, and 33.7% and 14.4% of the variances were explained by factor 1 (MDD) and factor 2 (patient grief symptoms), respectively. They were the only eigenvalues much greater than 1; Factor 3 resided at the elbow of the scree plot of the eigenvalues (see Figure 1) and no remaining factors account for a large amount of the variance in the data. The standardized Cronbach's α was 0.86 for the twelve patient grief symptoms; it was 0.90 for the MDD symptoms.</p> <p>Graph: FIGURE 1 Scree plot of factor analysis of PGD versus MDD.</p> <p>Patient grief appeared to be relatively distinct from MDD but there was overlap between the syndromes (Table 2). Eighty-three percent of the 6 patients with MDD met criteria for patient grief "caseness" but only 38% of the 13 patients with patient grief "caseness" (i.e., those in the upper 10% of the ICG–R distribution) met diagnostic criteria for MDD. In other words, nearly two-thirds of cases of patient grief would have been missed by sole reliance on diagnostic criteria for MDD. As expected, the Fisher's exact test showed a significant positive association between patient grief "caseness" and MDD (<emph>p</emph> &lt; 0.0001). When MDD was assessed using the Endicott criteria, the results were the same.</p> <p>TABLE 2 Patient Grief Disorder vs. Major Depression Disorder</p> <p> <ephtml> &lt;table&gt;&lt;thead valign="bottom"&gt;&lt;tr&gt;&lt;td /&gt;&lt;td&gt;Patient grief disorder&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td&gt;Major depression disorder&lt;/td&gt;&lt;td&gt;No&lt;/td&gt;&lt;td&gt;Yes&lt;/td&gt;&lt;td&gt;Total&lt;/td&gt;&lt;/tr&gt;&lt;/thead&gt;&lt;tbody&gt;&lt;tr&gt;&lt;td&gt;No&lt;/td&gt;&lt;td char="rpar" charoff="50"&gt;109 (88.6%)&lt;/td&gt;&lt;td char="rpar" charoff="50"&gt;8 (6.5%)&lt;/td&gt;&lt;td char="rpar" charoff="50"&gt;117 (95.1%)&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td /&gt;&lt;td char="rpar" charoff="50"&gt;(93.2%)&lt;/td&gt;&lt;td char="rpar" charoff="50"&gt;(6.8%)&lt;/td&gt;&lt;td /&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td /&gt;&lt;td char="rpar" charoff="50"&gt;(99.1%)&lt;/td&gt;&lt;td char="rpar" charoff="50"&gt;(61.5%)&lt;/td&gt;&lt;td /&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td&gt;Yes&lt;/td&gt;&lt;td char="rpar" charoff="50"&gt;1 (0.8%)&lt;/td&gt;&lt;td char="rpar" charoff="50"&gt;5 (4.1%)&lt;/td&gt;&lt;td char="rpar" charoff="50"&gt;6 (4.9%)&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td /&gt;&lt;td char="rpar" charoff="50"&gt;(16.7%)&lt;/td&gt;&lt;td char="rpar" charoff="50"&gt;(83.3%)&lt;/td&gt;&lt;td /&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td /&gt;&lt;td char="rpar" charoff="50"&gt;(0.9%)&lt;/td&gt;&lt;td char="rpar" charoff="50"&gt;(38.5%)&lt;/td&gt;&lt;td /&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td&gt;Total&lt;/td&gt;&lt;td char="rpar" charoff="50"&gt;110 (89.4%)&lt;/td&gt;&lt;td char="rpar" charoff="50"&gt;13 (10.6%)&lt;/td&gt;&lt;td char="rpar" charoff="50"&gt;123 (100.0%)&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td /&gt;&lt;/tr&gt;&lt;/tbody&gt;&lt;/table&gt; </ephtml> </p> <p>Patient grief "caseness," but not MDD, was uniquely associated with the wish to die (OR 10.13 [0.1.08–95.06]). Both depression and grief were significantly associated with mental health service use (OR Depression 16.07 [1.68, 153.77] vs. Grief 4.82 CI = [1.09, 21.41]) and negative religious coping (OR Depression 1.36 [1.06, 1.73] vs. Grief 1.25 [1.05, 1.49]); neither was associated with terminal illness acknowledgement.</p> <hd id="AN0048207671-6">Discussion</hd> <p>This study confirms that in patients with advanced cancer, a subset of patients have multiple symptoms of grief that are distinct from symptoms of depression and that, at syndromal (or "caseness") levels, are significantly associated with morbidity such as wish to die and mental health service use. Future research will be needed to distinguish a more intensified and pathological grieving process from normal grief, to determine criteria for a grief disorder among patients, and to determine which symptoms of grief are severe, distressing, and persistent enough to warrant treatment. However, the results of the factor analysis suggest that the underlying constructs and phenomenology of grief and depression are significantly different.</p> <p>Our study lacked data to assess the duration of the symptoms of grief. Therefore it is difficult to determine whether our symptom cluster of patient grief is a transient phenomenon and a part of a normal reaction to a terminal diagnosis or is a part of a prolonged and pathological grieving process. PGD is distinguished from normal grief in the literature on bereaved participants using duration (symptoms lasting longer than six months) and function (Prigerson et al., [<reflink idref="bib42" id="ref47">42</reflink>]). However, pathological grief has not been defined for terminally ill patients, and the criterion of duration is similarly difficult to define as the index event that triggers a grief reaction (e.g., a cancer diagnosis or discussion of a terminal prognosis) needs to be identified and the reaction to each examined for similarities and differences. Additionally, early in the course of their disease patients lose their health, later they lose function, independence, and control, and finally they confront losing life itself including the loss of significant relationships. There is a need for greater clarity as to what it is the patient is grieving.</p> <p>It is also difficult to apply the PGD criteria of duration to dying patients because, unlike the case of bereavement following death, there is often no index event marking the beginning of the loss of health. Whereas family members may engage in anticipatory grief prior to the death of a loved one, their period of bereavement is clearly delineated by the death of the patient. In contrast, terminally ill cancer patients have often learned their prognosis in steps, making it more difficult to define when the patient experiences the loss of health. For example, patients with early disease (stage 1, 2, or 3) may begin to grieve the loss of health, but may not see themselves as facing mortality. Similarly, patients given a 10% chance of cure may partially grieve thinking that they will not survive, yet not fully grieve because of the chance of recovery. If arriving at a terminal diagnosis involves several steps, it is difficult to determine how long "normal" grief should last, and where pathological grief begins. In this context, the duration of symptoms seems less relevant than the intensity of symptoms and their impact on function. The associations of the grief symptoms in our study with a wish for death and mental health service use suggest that there is substantial distress and impairment associated with severe (but not necessarily prolonged) grief symptoms among patients. Future research on this topic should focus on distinguishing pathological grief from normal grief based on criteria other than duration such as the intensity of grief, disability, and decrements in ability to enjoy the time remaining.</p> <p>In the bereaved, the symptoms clusters and treatments of grief and depression are different, therefore this distinction may also be important in terminally ill patients. In the bereaved, antidepressant treatment alone (Jacobs, Nelson, &amp; Zisook, [<reflink idref="bib22" id="ref48">22</reflink>]) and with interpersonal psychotherapy are effective in reducing depressive symptoms, but relatively ineffective for symptoms of bereavement-related grief (Pasternak et al., [<reflink idref="bib34" id="ref49">34</reflink>]; Reynolds et al., [<reflink idref="bib44" id="ref50">44</reflink>]). In contrast, randomized, controlled trials of psychotherapy designed specifically for PGD have demonstrated efficacy for PGD symptoms (Boelen, de Keijser, van den Hout, &amp; van den Bout, [<reflink idref="bib4" id="ref51">4</reflink>]; Shear, Frank, Houck, &amp; Reynolds, [<reflink idref="bib46" id="ref52">46</reflink>]). Future studies are needed to determine whether treatments that ameliorate symptoms of grief in the bereaved work equally well to reduce patient grief. In addition, future work should assess if patients with high levels of grief derive particular benefit from psychotherapeutic interventions designed to address psychosocial and existential distress among the terminally ill such as Chochinov's Dignity Therapy (Chochinov et al., [<reflink idref="bib9" id="ref53">9</reflink>]) or Breitbart's meaning-centered group psychotherapy (Breitbart, [<reflink idref="bib7" id="ref54">7</reflink>]; Breitbart, Gibson, Poppito, &amp; Berg, [<reflink idref="bib8" id="ref55">8</reflink>]; Greenstein &amp; Breitbart, [<reflink idref="bib18" id="ref56">18</reflink>]). Similarly, the literature around traumatic loss and the reconstruction of meaning may offer guidance for how to assist grieving patients with the reconstruction of a meaningful narrative of self and world in the wake of ongoing loss (Neimeyer, van Dyke, &amp; Pennebaker, [<reflink idref="bib29" id="ref57">29</reflink>]).</p> <p>Aside from depression, another mood disorder discussed in the literature on mental distress among dying patients is demoralization. Demoralization has been defined on the basis of case reports (Clarke &amp; Kissane, [<reflink idref="bib10" id="ref58">10</reflink>]; de Figueiredo, [<reflink idref="bib12" id="ref59">12</reflink>]; Griffith &amp; Gaby, [<reflink idref="bib19" id="ref60">19</reflink>]; Shader, [<reflink idref="bib45" id="ref61">45</reflink>]; Slavney, [<reflink idref="bib48" id="ref62">48</reflink>]) and factor analysis (Clarke, Kissane, Trauer, &amp; Smith, [<reflink idref="bib11" id="ref63">11</reflink>]; Kissane et al., [<reflink idref="bib25" id="ref64">25</reflink>]), although a consensus definition has not been reached and the syndrome has not been accepted into the International Classification of Disease (ICD) or the <emph>DSM</emph> (Ganzini &amp; Prigerson, [<reflink idref="bib15" id="ref65">15</reflink>]). <emph>Demoralization</emph> is generally described as a syndrome of hopelessness, despair, and subjective incompetence in the setting of repeated perceived failures or inability to meet expectations (Clarke &amp; Kissane, [<reflink idref="bib10" id="ref66">10</reflink>]). Kissane (Kissane et al., [<reflink idref="bib25" id="ref67">25</reflink>]) used factor analysis to divide demoralization into five subscales: loss of meaning and purpose, dysphoria, disheartenment, helplessness, and sense of failure.</p> <p>There is some overlap in our patient-grief scale and Kissane's concept of demoralization. Both grief and demoralization are characterized by symptoms of disillusionment such as a loss of meaning or disheartenment (emotional pain or sorrow on the patient grief scale), and sense of failure (confusion about role in life, significant reduction in ability to function on the patient grief scale). However, patient grief is different from demoralization in that grief also includes agitated psychological symptoms such as yearning, avoidance, and difficulty accepting one's illness and trusting others. And, whereas the definition of demoralization might include dysphoric feelings such as subjective incompetence and bitterness about one's illness, our grief symptoms of feeling shocked, dazed, and emotionally numb are more related to symptoms of traumatic distress than they are to symptoms of dysphoria.</p> <p>Even though the work of bereavement and the work of dying both involve processing significant interpersonal loss, they are fundamentally different, so the criteria for one may not apply well to the other. The work of bereavement involves an acceptance of the loved one's death followed by a reintegration into life. For the bereaved, symptoms of prolonged grief revolve around the deficiencies in acceptance (yearning, disbelief, bitterness) and withdrawal (decreased social functioning, difficulty trusting others, difficulty moving on with life, emotional numbness, or detachment from others). In contrast, the work of dying involves an acceptance of one's own death and ultimately a letting go of life. Grief symptoms such as confusion about one's role in life, decreased social functioning, difficulty concentrating, and detachment from others are not necessarily pathological and can all be normal parts of dying, where patients lose their abilities to function physically, cognitively, and emotionally and must adapt to new ways of living and relating to others. Future research should address how to distinguish the integrative, reinvestment work of grief related to bereavement from the disengaging and relinquishing work of grief related to dying. In addition, future work should explore common qualities of grief in the bereaved and the dying. For example, the process of grief for the bereaved may evoke growth-promoting qualities that eventually enable the bereaved to reengage and invest in life despite the loss. These growth-promoting qualities should be explored and defined both in the bereaved and the terminally ill, as they may have a significant impact on the experience of the terminally ill patients, and may either facilitate or inhibit growth at the end of life.</p> <hd id="AN0048207671-7">Acknowledgments</hd> <p>This research was supported in part by the following grants: MH56529 (HGP) from the National Institute of Mental Health and CA106370 (HGP) from the National Cancer Institute; a grant from the American Foundation for Suicide Prevention; and the Center for Psycho-oncology and Palliative Care Research, Dana-Farber Cancer Institute (HGP, BZ, PKM).</p> <ref id="AN0048207671-8"> <title> References </title> <blist> <bibl id="bib1" idref="ref46" type="bt">1</bibl> <bibtext> Barry, L.

This study is an attempt to replicate this finding among advanced cancer patients and examine clinical correlates of patient grief and depression. Analyses were conducted on data from interviews with 123 advanced cancer patients. Grief was measured using symptoms from the patient version of the Inventory of Complicated Grief-Revised (ICG-R) and symptoms of depression were assessed using the Structured Clinical Interview for DSM-IV (SCID). A factor analysis revealed that symptoms of patient grief formed a coherent factor that was distinct from a depression factor. Patient grief "caseness" (defined as being in the top 10% of the distribution of grief scores), but not major depressive disorder, was uniquely associated with the wish to die (odds ratio [OR] 10.13 [0.1.08-95.06]). Both depression and grief were significantly associated with mental health service use (OR 16.07 [1.68, 153.77] vs. 4.82; CI = [1.09, 21.41]) and negative religious coping (OR 1.36 [1.06, 1.73] vs. 1.25 [1.05, 1.49]); neither was associated with terminal illness acknowledgement.
