          Abstract

          Purpose

          Depression is highly prevalent in advanced cancer patients, but the diagnosis of depressive disorder in patients with advanced cancer is difficult. Screening instruments could facilitate diagnosing depressive disorder in patients with advanced cancer. The aim of this study was to determine the validity of the Beck Depression Inventory (BDI-II) and a single screening question as screening tools for depressive disorder in advanced cancer patients.

          Methods

          Patients with advanced metastatic disease, visiting the outpatient palliative care department, were asked to fill out a self-questionnaire containing the Beck Depression Inventory (BDI-II) and a single screening question “Are you feeling depressed?” The mood section of the PRIME-MD was used as a gold standard.

          Results

          Sixty-one patients with advanced metastatic disease were eligible to be included in the study. Complete data were obtained from 46 patients. The area under the curve of the receiver operating characteristics analysis of the BDI-II was 0.82. The optimal cut-off point of the BDI-II was 16 with a sensitivity of 90% and a specificity of 69%. The single screening question showed a sensitivity of 50% and a specificity of 94%.

          Conclusions

          The BDI-II seems an adequate screening tool for a depressive disorder in advanced cancer patients. The sensitivity of a single screening question is poor.

          On the validity of the Beck Depression Inventory. A review.

          The present review discusses validity aspects of the Beck Depression Inventory (BDI) on the basis of meta-analyses of studies on the psychometric properties. Shortcomings of the BDI are its high item difficulty, lack of representative norms, and thus doubtful objectivity of interpretation, controversial factorial validity, instability of scores over short time intervals (over the course of 1 day), and poor discriminant validity against anxiety. Advantages of the inventory are its high internal consistency, high content validity, validity in differentiating between depressed and nondepressed subjects, sensitivity to change, and international propagation. The present paper outlines agreements and contradictions between the various studies on the BDI and discusses the potential factors (composition of the subject sample, statistical procedures, point in time of measurement) accounting for the variance in their results. The Beck Depression Inventory (BDI) is world-wide among the most used self-rating scales for measuring depression. Since the test construction in 1961, the test has been employed in numerous (more than 2,000) empirical studies. The present review will only consider those investigations which are primarily concerned with the validity or the psychometric properties of the BDI. Since most studies are oriented along the criteria of the classical test theory, our review will discuss to what extent the BDI meets these criteria.

            Oncologists' recognition of depression in their patients with cancer.

            This study was performed as part of a large depression screening project in cancer patients to determine the degree of physician recognition of levels of depressive symptoms in cancer patients and to describe patient characteristics that influence the accuracy of physician perception of depressive symptoms. Twenty-five ambulatory oncology clinics affiliated with Community Cancer Care, Inc of Indiana enrolled and surveyed 1,109 subjects treated by 12 oncologists. Subjects completed the Zung Self-Rating Depression Scale (ZSDS) and physicians were asked to rate their patients' level of depressive symptoms, anxiety, and pain using numerical rating scales. Subjects' sex, age, primary tumor type, medications, primary caregiver, and disease stage at diagnosis were also recorded. Physician ratings of depression were significantly associated with their patients' levels of endorsement of depressive symptoms on the ZSDS. However, agreement between physicians and patients is most frequently clustered when patients report little or no depressive symptoms. While physician ratings are concordant with patient endorsement of no significant depressive symptomatology 79% of the time, they are only concordant 33% and 13% of the time in the mild-to-moderate/severe ranges, respectively. Physician ratings were most influenced by patient endorsement of frequent and obvious mood symptoms, ie, sadness, crying, and irritability. Physician ratings also appeared to be influenced by medical correlates of patients' level of depressive symptoms (functional status, stage of disease, and site of tumor). Additionally, patients whose depression was inaccurately classified reported significantly higher levels of pain and had higher levels of disability. Physicians' ratings of depression were most highly correlated with physicians' ratings of patients' anxiety and pain. Physicians' perceptions of depressive symptoms in their patients are correlated with patient's ratings, but there is a marked tendency to underestimate the level of depressive symptoms in patients who are more depressed. They are most influenced by symptoms such as crying and depressed mood, and medical factors that are useful, but not the most reliable, indicators of depression in this population. Physicians' ratings of their patients' distress symptoms seem to be global in nature--they are highly correlated with anxiety, pain, and global dysfunction. Physician assessment might be improved if they were instructed to assess and probe for the more reliable cognitive symptoms such as anhedonia, guilt, suicidal thinking, and hopelessness. Screening instruments and the use of brief follow-up interviews would help to identify patients who are depressed.

              Depression in cancer: new developments regarding diagnosis and treatment.

              Considerable data demonstrate the high prevalence of symptoms of depression in patients with a wide variety of neoplastic disorders. Moreover, the dire consequences of these depressive symptoms in cancer patients have been well documented. Recent conceptual developments in the potential contributing mechanisms include increasing appreciation of the possibility that behavioral alterations in cancer patients may represent a "sickness syndrome" that results from activation of the inflammatory cytokine network. This sickness syndrome, which has been well documented in patients and laboratory animals exposed to inflammatory cytokines, includes symptoms that overlap with those seen in major depression. Conceptualizing these symptoms as components of cytokine-mediated sickness behavior has several important, and potentially novel, implications, including 1) an expansion of the neurobehavioral symptoms that are relevant to diagnosis and treatment; and 2) an increased appreciation of the potential diagnostic utility of peripheral markers of inflammation, as well as cytokine-related neurocircuitry alterations as defined by brain imaging. Treatment implications focus on the pathways by which inflammatory cytokines influence behavior, including therapeutic targets such as the inflammatory cytokines themselves, corticotropin-releasing hormone, and monoaminergic neurotransmitters and their precursors. Finally, recent data suggest that aggressive treatment strategies initiated before inflammation-inducing cancer treatments might prevent behavioral alterations, including depression, before they occur.
