Developing brief scales for use in clinical practice: the reliability and validity of single-item self-report measures of depression symptom severity, psychosocial impairment due to depression, and quality of life.

OBJECTIVE: Reliable, valid, user-friendly measurement is necessary to successfully implement an outcomes evaluation program in clinical practice. Self-report questionnaires, which generally correlate highly with clinician ratings, are a cost-effective assessment option. However, even self-administered questionnaires can be burdensome to patients because many are lengthy. Consequently, we developed and determined the reliability and validity of ultra-brief, single-item assessments of 3 domains important to consider when treating depressed patients: symptom severity, psychosocial functioning, and quality of life. METHOD: In the first study (conducted June 1997 to March 2002), 1278 psychiatric outpatients with various DSM-IV diagnoses completed single-item assessments of psychosocial functioning and quality of life as well as more detailed measures of these constructs. In the second study (conducted August 2003 to July 2004), 562 psychiatric outpatients who were in ongoing treatment for a DSM-IV major depressive episode completed a depression symptom scale and a measure of global severity of depression. RESULTS: The test-retest reliability of the psychosocial functioning and quality-of-life items was high. The single-item measures of symptom severity, psychosocial functioning, and quality of life were significantly correlated with the total scores and individual item scores of longer measures of the same constructs (p < .001). The single-item measures significantly discriminated between depressed patients in full remission, in partial remission, and in a current depressive episode (p < .001). CONCLUSION: These studies provide evidence of the reliability and validity of single-item measures of symptom severity, psychosocial functioning, and quality of life. Very brief measures, such as the ones described in the present report, are not burdensome for patients to complete and can be easily incorporated into a busy clinical practice in order to collect data on treatment effectiveness.

Major depressive disorder and depressive symptomatology as predictors of husband to wife physical aggression.

This study investigated the association between a husband's depressive symptomatology and the frequency of physical aggression toward his wife, as well as a husband's Major Depressive Disorder (MDD) and the frequency of physical aggression toward his wife. We assessed physically aggressive men who volunteered for treatment with their wives (N = 89). Almost one third had moderate levels of depressive symptomatology (Beck Depression Inventory [BDI > or = 14]), but only 11% met criteria for MDD (based on a structured interview [SCID]). Although the rate of MDD was not absolutely high, it was higher than that reported in a community sample (i.e., 3%). A significant relationship between increased depressive symptomatology and frequency of physical aggression was found, but the association was most likely accounted for by self-reported anger. Related contextual factors including marital discord and psychological aggression are addressed. Theoretical and treatment implications are discussed, including the severity of the treatment population (volunteer vs. court mandated), and severity of the depression (symptomatology vs. clinical diagnosis).

[Diagnosis of depressive disorder and so-called exhaustion depression. Self-esteem--a central concept].

Depressive disorders can be recognized by the loss of self-esteem; this contrasts with mourning and neurasthenic reactions, in which self-esteem remains intact. Just as depression can result from the gradual reduction and eventual loss of self-esteem, mourning and neurasthenic reactions can evolve into true depressive states. "Exhaustion depression", a new diagnostic category connected to "burnout" situations, should be applied only when criteria for depressive disorder are fulfilled, including loss of self-esteem. When these criteria are lacking we should refer only to an exhaustion state provoked by stress. Neurotic mechanisms may represent a special class of relevant stress factors, but are not seen in manifest neurasthenic reactions and exhaustion depression.

Prediction of recurrence in recurrent depression and the influence of consecutive episodes on vulnerability for depression: a 2-year prospective study.

OBJECTIVE: Depression is a recurring disease. Identifying risk factors for recurrence is essential. The purpose of this study was to identify factors predictive of recurrence and to examine whether previous depressive episodes influence vulnerability for subsequent depression in a sample of remitted recurrently depressed patients. METHOD: Recurrence was examined prospectively using the Structured Clinical Interview for DSM-IV Axis I Disorders in 172 euthymic patients with recurrent depression (DSM-IV) recruited from February 2000 through September 2000. Illness-related characteristics, coping, and stress (life events and daily hassles) were examined as predictors. RESULTS: Risk factors for recurrence were a high number of previous episodes, more residual depressive symptomatology and psychopathology, and more daily hassles. Factors with both an increasing and decreasing pathogenic effect with increasing episode number were detected. CONCLUSION: We found some support for dynamic vulnerability models that posit a change of vulnerability with consecutive episodes. Preventive interventions should be considered in patients with multiple recurrences, focusing on residual symptomatology and specific coping styles.

[Masked depression and paucisymptomatic depression (author's transl)].

All depressive syndromes include physical as well as psychological features. Physical symptoms in major "endogenous" depression are well known. In other forms, called masked depressions, various physical disorders are the patients main complaint and may be misleading. Localized pain and paresthesia are common. Behaviour disorders may mask depression in adolescents. Mood disturbances (loss of interest, anhedonia) as well as the personal and family histories, should be precisely assessed in order to establish diagnosis. Masked depression is not a minor form of depressive syndrome and antidepressant drugs should be used in correct doses over a sufficient period of time.

Adrenergic receptor sensitivity in depression. Effects of clonidine in depressed patients and healthy subjects.

Several recent investigations have raised the possibility that the sensitivity of alpha 2-adrenergic receptor may be of etiologic importance in depression. To assess whether abnormalities in presynaptic alpha 2-adrenergic receptor exist in depressed patients not taking drugs, the effects of an alpha 2 agonist, clonidine, on plasma 3-methoxy-4-hydroxyphenelethyleneglycol (MHPG) and on blood pressure (BP) were evaluated in 15 depressed patients and 12 healthy controls of similar age. The ability of clonidine to increase growth hormone (GH) secretion was also assessed. The effect of clonidine on plasma MHPG and BP was not different between the depressed patients and controls. However, the GH response to clonidine was blunted in the depressed patients. These results suggest that in depression (1) the sensitivity of the presynaptic alpha 2-adrenergic receptor is not abnormal, and (2) the sensitivity of postsynaptic adrenergic receptors may be decreased.

Growth hormone secretion in prepubertal children with major depression. I. Final report on response to insulin-induced hypoglycemia during a depressive episode.

Insulin tolerance tests (ITTs) were carried out on 46 drug-free prepubertal children with severe emotional disorders. Thirteen met unmodified Research Diagnostic Criteria for major depressive disorder, definite endogenous subtype, 17 met the criteria for nonendogenous major depressive disorder, and 16 fit DSM-III criteria for nondepressed neurotic disorders. The group with endogenous depression had significant hyposecretion of growth hormone (GH) in this test when compared with the other groups. Since GH hyposecretion in response to ITT has been found in most studies to be associated with endogenous major depression in adults, the data support the validity of the diagnosis of prepubertal endogenous major depressive disorder and the hypothesis of similarity or identity of prepubertal and adult major depressive disorders.

Growth hormone secretion in prepubertal children with major depression. III. Response to insulin-induced hypoglycemia after recovery from a depressive episode and in a drug-free state.

Insulin tolerance tests (ITTs) were performed after at least four months of sustained recovery from an episode of a major depressive disorder in 18 drug-free prepubertal children. Eleven had a definite endogenous subtype; seven did not. Sixteen children with nondepressed neurotic disorders made up a control group. The children with past endogenous depression continued to have significant hyposecretion of growth hormone (GH) in this test when compared with the other groups. Illness-recovery correlations were highly significant for the major depressive group as a whole. Paired comparisons of both depressive groups were not significantly different from illness to recovery. We conclude that prepubertal children with endogenous major depression continue to have hyposecretion of GH in response to ITTs in a recovered state and that this neuroendocrine marker is state independent. A GH hyporesponse to ITT may be a true marker of a past episode or of trait for endogenous major depressive disorder in prepuberty.

Depression and immunity. Lymphocyte function in ambulatory depressed patients, hospitalized schizophrenic patients, and patients hospitalized for herniorrhaphy.

Mitogen-induced lymphocyte stimulation responses in ambulatory patients with major depressive disorder did not differ from those of matched controls. Lymphocyte responses in hospitalized schizophrenic patients and in patients hospitalized for elective herniorrhaphy similarly did not differ from responses of controls. The number of peripheral-blood T cells was decreased among the ambulatory depressed patients but not in the schizophrenic patients. These findings, together with previously reported decreased lymphocyte function in hospitalized depressed patients, suggest that decreased lymphocyte function is associated specifically with depression and not related to hospital effects or nonspecifically to other psychiatric disorders. The results also suggest that altered immunity in depression may be related to severity of depressive symptoms.

Course of depressive symptoms over follow-up. Findings from the National Institute of Mental Health Treatment of Depression Collaborative Research Program.

We studied the course of depressive symptoms during an 18-month naturalistic follow-up period for outpatients with Major Depressive Disorder treated in the National Institute of Mental Health Treatment of Depression Collaborative Research Program. The treatment phase consisted of 16 weeks of randomly assigned treatment with the following: cognitive behavior therapy, interpersonal therapy, imipramine hydrochloride plus clinical management (CM), or placebo plus CM. Follow-up assessments were conducted at 6, 12, and 18 months after treatment. Of all patients entering treatment and having follow-up data, the percent who recovered (8 weeks of minimal or no symptoms following the end of treatment) and remained well during follow-up (no Major Depressive Disorder relapse) did not differ significantly among the four treatments: 30% (14/46) for those in the cognitive behavior therapy group, 26% (14/53) for those in the interpersonal therapy group, 19% (9/48) for those in the imipramine plus CM group, and 20% (10/51) for those in the placebo plus CM group. Among patients who had recovered, rates of Major Depressive Disorder relapse were 36% (8/22) for those in the cognitive behavior therapy group, 33% (7/21) for those in the interpersonal therapy group, 50% (9/18) for those in the imipramine plus CM group, and 33% (5/15) for those in the placebo plus CM group. The major finding of this study is that 16 weeks of these specific forms of treatment is insufficient for most patients to achieve full recovery and lasting remission. Future research should be directed at improving success rates of initial and maintenance treatments for depression.

The relationship of demographic variables, antepartum depression, and stress to postpartum depression.

This study examined the contributions of demographic variables, antepartum depressive symptoms, and sources of stress to level of postpartum depression. The Beck Depression Inventory (BDI) and demographic data sheet were administered to 69 women during the eighth month of pregnancy. One month after delivery, subjects completed the post-delivery questionnaire and BDI. A stratified hierarchical regression analysis revealed that marital status, antepartum depressive symptoms, and difficulty of pregnancy predicted level of postpartum depression. Somatic stressors of pregnancy may trigger depressive symptoms that persist after childbirth, particularly in unmarried mothers.

Dissociation between synaptic depression and block of long-term depression induced by raising the temperature in rat hippocampal slices.

The influence of raising the bath temperature (39 degrees C) on synaptic transmission and neuronal plasticity was studied in the CA1 region of the rat hippocampus using an extracellular recording technique. Increasing the bath temperature from 32 to 39 degrees C resulted in a depression of field excitatory postsynaptic potential (fEPSP). Application of the selective A(1) receptor agonist, 2-chloro-adenosine (2-CADO, 1 microM) reduced the fEPSP and subsequently occluded the raised temperature-induced synaptic depression. On the other hand, the selective adenosine A(1) receptor antagonist 8-cyclopentyl-1, 3-dipropylxanthine (DPCPX) blocked depression of fEPSP produced by raising the temperature. These results suggest that raising temperature-induced synaptic depression is due to an alteration of extracellular adenosine concentration. Long-term depression (LTD) could be reliably induced by the standard low-frequency stimulation (LFS, 1 Hz for 15 min) protocol at 32 degrees C but not at 39 degrees C. The raised temperature-induced block of LTD was mimicked by 2-CADO. Unexpectedly, despite the presence of DPCPX, LFS still could not elicit LTD. NMDA receptor-mediated synaptic component (fEPSP(NMDA)) was decreased when increasing the temperature to 39 degrees C and DPCPX failed to reverse such a depression. The increase in the NMDA response in 0.1 mM Mg(++) compared with 1 mM Mg(++) was significantly greater at 32 degrees C than at 39 degrees C. These results suggest that, by increasing the sensitivity of Mg(++) block, an increase in temperature modulates NMDA responses and thereby inhibits the induction of LTD.

A comparison of self-reported function assessed before and after depression treatment among depressed geriatric inpatients.

The purpose of this study was to determine whether self-perception of function among depressed, geriatric psychiatry inpatients improved as their depression resolved. Sixty-four older adults diagnosed with major depression were asked to evaluate their function upon admission to an inpatient psychiatry unit, and then again 3 months post-discharge. Subjects' caregivers also rated the patients' function at admission and 3 months after being discharged. Self-perceptions of function improved over time, while caregivers' perceptions remained stable, suggesting that patients' perceptions of function is in part influenced by their depression. Further, correlations between patient and caregiver perceptions of function were higher at 3 months post discharge (when patients were not depressed) than they were at admission. The implication is that self-perceptions of function are more accurate when not depressed.

The validity of the Beck Depression Inventory as a screening and diagnostic instrument for depression in patients with Parkinson's disease.

PURPOSE: To evaluate the validity of the Beck Depression Inventory (BDI) as a screening and diagnostic scale for depression in Parkinson's disease (PD). PATIENTS AND METHODS: Fifty-three nondemented patients with PD were diagnosed according to a standardized protocol consisting of the depression module of the Structured Clinical Interview for DSM axis I disorders (SCID) and the BDI. A "receiver operating characteristics" (ROC) curve was obtained and the sensitivity, specificity, positive and negative predictive values (PPV and NPV, respectively) were calculated for different cut-off points of the BDI. RESULTS: Maximum discrimination was obtained with a cut-off score of 13/14. High sensitivity and NPV were obtained with cut-off scores of 8/9 or lower; a high specificity and PPV were obtained with cut-off scores of 16/17 or higher. The area under the ROC curve was 85.67%. CONCLUSION: A single cut-off score on the BDI to distinguish nondepressed from depressed patients with PD is not feasible. If one accepts the low specificity, then the BDI can be used as a valid screening instrument for depression in PD with a cut-off of 8/9. With a cut-off score of 16/17, it can be used as a diagnostic scale, at the cost of a low sensitivity. The use of diagnostic criteria for depression remains necessary.

Measurement of depression in Mexican patients with rheumatoid arthritis: validity of the Beck Depression Inventory.

OBJECTIVE: To validate a Spanish version of the Beck Depression Inventory (BDI) in Mexican patients with rheumatoid arthritis (RA). METHODS: Thirty-five patients with RA seen in our outpatient clinic were included. A semistructured psychiatric interview was applied, and the following instruments were administered: the BDI, the Hospital Anxiety and Depression Scale (HAD), and the Health Assessment Questionnaire Disability Index. Diagnostic properties of the BDI for both full-length and smaller versions taking out somatic items were compared against a gold standard. The gold standard for comparison was the diagnosis of depression according to the Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised Criteria. RESULTS: Thirty-seven percent of RA patients had a diagnosis related to depression, most of which were major depression or dysthymia. The original BDI showed a high sensitivity (92%) and a high correlation with the HAD (r = 0.83). Exclusion of somatic items in modified versions of the BDI had a similar performance. CONCLUSIONS: The original BDI is a suitable instrument to detect depression in Mexican RA patients. Nevertheless, shorter versions without some of the somatic items also show an adequate performance.

The 15-item Geriatric Depression Scale (GDS-15) detects changes in depressive symptoms after a major negative life event. The Leiden 85-plus Study.

BACKGROUND: The 15-item Geriatric Depression Scale (GDS-15) is a widely used screening instrument for depressive symptoms in the elderly, but its ability to detect alterations in depressive symptoms over time has not been established. OBJECTIVE: To assess the change of the GDS-15 score after a major negative life event. METHODS: Within the Leiden 85-plus Study, we prospectively followed a population-based cohort of 599 subjects from 85 years onwards. The GDS-15 was applied annually to participants with a Mini-Mental State Examination (MMSE) score above 18 points. The change in GDS-15 score of 32 subjects who had lost their partner during follow-up was compared with a control group of 32 subjects who had not lost their partner, matched for age, sex, and initial GDS-15 score. RESULTS: At baseline, 241 subjects lived together with a partner. During a mean follow-up of 3.2 years, 55 participants (23%) lost their partner. Of those, 32 subjects completed the GDS-15 before and after the loss of their partner. All subjects reported the bereavement to be a major negative life event. The mean increase of the GDS-15 score after the death of a partner was 1.2 points (paired t-test, p = 0.013). This was significantly higher than the mean change of -0.06 points in the matched control group (independent t-test, p = 0.032), and independent of sex, level of education, pre-bereavement GDS-15 score, and time period since the loss of a partner. CONCLUSION: This study shows that the GDS-15 detects change in depressive symptoms after loss of a partner, a negative life event that is the most important risk factor for depression in the elderly. Therefore, it may be concluded that the GDS-15 has the ability to measure longitudinal alterations in depressive symptomatology.

Socioeconomic status, depression disparities, and financial strain: what lies behind the income-depression relationship?

Prior studies have consistently found the incidence and persistence of depression to be higher among persons with low incomes, but causal mechanisms for this relationship are not well understood. This study uses the National Longitudinal Survey of Youth 1979 cohort to test several hypotheses about the robustness of the depression-income relationship among adults. In regressions of depression symptoms on income and sociodemographic variables, income is significantly associated with depression. However, when controls for other economic variables are included, the effect of income is considerably reduced, and generally not significant. Employment status and the ratio of debts-to-assets are both highly significant for men and for women both above and below the median income. Fixed-effects estimates suggest that employment status and financial strain are causally related to depression, but income is not. Instrumental variable estimates suggest that financial strain may not lead to depression.

Course of depressive mood and psychomotor activation in endogenous depression.

The course of the depressive mood during depressive phases was measured by a self-rating mood scale and analyzed by various algorithms. Agitated, depressed patients often reveal a continuous decline in the depressive mood; retarded, depressed patients, on the other hand, often show brief and marked fluctuations in mood during remission. Although various effects occur due to treatment, especially differences between the effects of electroconvulsive therapy (ECT) and antidepressants, the described changes in mood appear to be predominantly due to psychomotor activation. The relationship between these courses of depression is discussed and interpreted on the basis of biochemical and psychopharmacologic findings.
