Depressive symptom profile in Parkinson's disease: a comparison with depression in elderly patients without Parkinson's disease.

OBJECTIVE: Depression is a common neuropsychiatric syndrome in Parkinson's disease (PD), and may be etiologically related to the neurochemical changes accompanying this disease. It is still unclear whether the disturbances of neurotransmitter activities lead to a specific profile of depressive symptoms, that is characteristic for PD and differs from that in depressed patients without PD. METHOD: We compared the individual depressive symptoms of 145 non-demented depressed patients with PD and 100 depressed patients without PD by comparing item scores on the Montgomery-Asberg Depression Rating Scale by way of MANCOVA. RESULTS: The severity of depression and the level of cognitive functioning in depressed PD patients were comparable with that of depressed control subjects. However, patients with PD showed significant less reported sadness, less anhedonia, less feelings of guilt and, slightly less loss of energy, but more concentration problems than depressed control subjects. CONCLUSION: The profile of depressive symptoms in PD differs from that in depressed subjects without PD. This finding is important for the conceptualisation and clinical diagnosis of depression in PD.

Public belief systems about the helpfulness of interventions for depression: associations with history of depression and professional help-seeking.

BACKGROUND: Previous research has found that there are major differences between public and professional beliefs about the helpfulness of interventions for depression. The public appear to be guided by general belief systems about the helpfulness of medical, psychological and lifestyle interventions rather than by specific knowledge about what interventions are effective for depression. The present paper examines the effect that experiencing depression and receiving treatment might have on these beliefs. METHOD: The study involved a postal survey of 3109 adults from a region of New South Wales, Australia. Respondents were presented with a vignette describing a person with depression. They were asked to rate the likely helpfulness of various types of professional and non-professional help and of pharmacological and non-pharmacological interventions for the person described in the vignette. Respondents also completed the Goldberg Depression Scale and were asked whether they had ever had an episode of depression and whether they had seen a counsellor or a doctor for it at the time. Structural equation modelling was used to investigate the associations of history of depression and professional help-seeking with belief systems. RESULTS: A three-factor model was found to fit the helpfulness ratings, with factors reflecting beliefs in medical, psychological and lifestyle interventions. People who had sought help for depression were less likely to believe in the helpfulness of lifestyle interventions and more likely to believe in medical interventions. As well as these general associations with belief systems, having sought help for depression had a number of specific associations with beliefs. Controlling for general belief systems, those who had sought help were more likely to rate antidepressants, holidays, massage and new recreational pursuits as helpful, and were less likely to rate ECT and family as helpful. Those who had a history of depression but had not sought help were more likely to rate counselling as helpful, and less likely to rate family as helpful. Those with current depressive symptoms were less likely to rate telephone counselling, family and friends as helpful. CONCLUSION: Having sought help for depression is associated with general belief systems about the helpfulness of lifestyle and medical interventions and also has some associations with specific beliefs that may reflect experiences with treatment (e.g. the helpfulness of antidepressants). Those currently depressed or with a history of depression are less likely to regard family as helpful, possibly due to poorer social support. Generally speaking, having sought help is associated with beliefs closer to those of professionals.

EEG findings in depressive pseudodementia and dementia with secondary depression.

We report EEG findings in 33 elderly patients with mixed symptoms of depression and dementia, followed longitudinally to confirm diagnosis. Two groups of patients, dementia with depressive features (mixed-DEM, group I, n = 23) and patients with depressive pseudodementia (mixed-DEP, group II, n = 10), were defined. In addition, we also included, for comparison purposes, 35 patients with probable AD without depressive features (group III), 23 patients with major depression without cognitive impairment (group IV), and 61 healthy elderly controls (group V). We found significant group differences on waking EEGs between those mixed patients who did well after treatment for depression (depressive pseudodementia) compared to patients having dementia with secondary depression. The differences paralleled those between the 'pure' groups of demented and depressed patients. In patients with either depression or depressive pseudodementia, the EEG was usually normal or showed only mild abnormalities. In contrast, the majority of patients with either dementia or dementia with secondary depression had abnormal EEGs, with approximately one-third having moderate (or severe) abnormalities. Although the EEG was usually normal or only mildly abnormal in patients with pseudodementia or depression, these groups (II and IV) did show a significant slowing of the dominant posterior rhythm compared to controls. They also had a higher percentage of generalized abnormal EEGs than controls and this difference was significant between group IV (depression) and controls.

Verbal memory performance of patients with a first depressive episode and patients with unipolar and bipolar recurrent depression.

Depression is usually associated with episodic memory impairment. The main clinical features of depression associated with that memory impairment are not clearly defined. The main goal of that study was to assess the role of the diagnostic subtypes and the number of depressive episodes on the memory performance of acute unipolar (UP) and bipolar (BP) depressed patients.Twenty-three patients with a first major depressive episode (FE), 28 patients meeting DSM-IV criteria for UP recurrent depression (UR) and 18 BP patients with recurrent depression were compared with 88 healthy subjects on a verbal episodic memory task. Patients suffering from a first depressive episode did not show verbal memory impairment as compared to normal controls. Unlike FE patients, UR and BP patients exhibited verbal memory deficits with impaired free recall and normal cued recall and recognition. The memory deficits of the UR and BP patients was present in the first free recall trial. Depressed patients improved their memory performance across the three trials of the task at the same rate than normal controls. Our results suggest that the number of depressive episodes has a negative influence on verbal memory performance of acute depressed patients. The effects of the repetition of the depressive episodes are not modulated by the subtypes of depression and may reflect sensitization to the cognitive impact of depression associated with increasing prefrontal dysfunction.

Identification, course, and treatment of depression after admission for a cardiac condition: rationale and patient characteristics for the Identifying Depression As a Comorbid Condition (IDACC) project.

BACKGROUND: Given the prevalence of cardiovascular disease and the high rates of depression among cardiac patients, there is a need to develop practical ways to identify this population and provide pragmatic general-practitioner-based interventions for managing depression as a comorbid condition. METHOD: The Identifying Depression As a Comorbid Condition (IDACC) study employed a hybrid design, incorporating a randomized controlled trial nested within a prospective cohort study. IDACC screened for depression in patients hospitalized in South Australia for a range of cardiac conditions, with outcome measures monitored for 12 months after discharge. The subgroup identified as depressed was entered into the nested IDACC trial, which tests the hypothesis that identifying depression and offering an evidence-based intervention to general practitioners, incorporating multidisciplinary telephone case conferencing, will reduce levels of depression, improve quality of life, and reduce associated economic costs. RESULTS: At baseline, 46.3% of 1455 participants screened were classified as depression cases on the basis of their score on the Center for Epidemiological Studies Depression Scale (> or =16) or the Hospital Anxiety and Depression Scale (> or =8). Elevated scores were associated with being younger, female, divorced or separated, not employed, living alone, having a lower level of education, and having poorer health and quality of life. Nearly one fifth (19.4%) of participants had Center for Epidemiological Studies Depression Scale scores >27, which is indicative of major depression. CONCLUSIONS: This project confirms, in an Australian setting, the high prevalence of depressive symptoms among hospitalized cardiac patients. Follow-up over 12 months will enhance understanding of the natural history of depression in cardiac patients, while the nested trial will inform on effectiveness of an intervention involving tailored advice and support to general practitioners.

Screening for depression in pregnancy: characteristics of the Beck Depression Inventory.

OBJECTIVE: To determine the test characteristics of a self-report questionnaire, the Beck Depression Inventory, when used as a screening test for depression in a population of ambulatory pregnant women. METHODS: One hundred five pregnant women completed the Beck Depression Inventory and underwent a structured interview using the National Institute of Mental Health Diagnostic Interview Schedule-version III. Current depression was diagnosed according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders-III-R. A receiver operating characteristic curve was constructed for the Beck Depression Inventory score as a predictor of current depression. A table of sensitivities, specificities, predictive values, and likelihood ratios was created for various cutoff values. RESULTS: For the 105 women enrolled, the median Beck Depression Inventory score was 8.0. Twelve women (11%) were diagnosed with current depression and had a median Beck Depression Inventory score of 25.5, compared with those without current depression, who had a median score of 8.0 (P = .001). The area under the receiver operating characteristic curve was 0.9940. Using a cutoff range of greater than 16, the sensitivity of the Beck Depression Inventory to detect current depression was 0.83, the specificity was 0.89, the positive predictive value was 0.50, and the negative predictive value was 0.98. CONCLUSIONS: The Beck Depression Inventory can serve as a rapid screening test for depression during pregnancy. A higher cutoff value is required for pregnant women than is customarily used outside of pregnancy.

Longitudinal investigation of depression outcomes in primary care in six countries: the LIDO study. Functional status, health service use and treatment of people with depressive symptoms.

BACKGROUND: Screening surveys of depressive symptoms were conducted among primary care patients at six sites in different countries. The LIDO Study was designed to assess quality of life and economic correlates of depression and its treatment in culturally diverse primary health care settings. This paper describes: (1) the association between depressive symptoms and functional status, global health-related quality of life (QoL), and use of general health services across different cultural settings; and (2) among subjects with depressive symptoms, the factors associated with recent treatment for depression. METHODS: Subjects aged 18 to 75 were recruited from participating primary care facilities in Be'er Sheva (Israel), Porto Alegre (Brazil), Melbourne (Australia), Barcelona (Spain), St Petersburg (Russian Federation) and Seattle (USA). Depressive symptoms were measured using the CES-D. Also administered were the SF-12, global questions on QoL, selected demographic and social measures, and questions on recent treatment for depression, use of health care services, and lost workdays. RESULTS: A total of 18,489 patients were screened, of whom 37% overall (range 24-55%) scored > or = 16 on the CES-D and 28% (range 17-42%) scored > or = 20. Overall, 13% reported current treatment for depression (range 4 to 23%). Patients with higher depressive symptom scores had worse health, functional status, QoL, and greater use of health services across all sites. Among those with a CES-D score > or = 16, subjects reporting treatment for depression were more likely than those reporting no treatment to be dissatisfied with their health (except in St Petersburg), and to have higher depressive symptom scores. CONCLUSIONS: Higher depressive symptom scores in primary care patients were consistently associated with poorer health, functional status and QoL, and increased health care use, but not with demographic variables. The likelihood of treatment for depression was associated with perceptions of health, as well as severity of the depression.

The relationship between social support, depression and treatment for depression in people with multiple sclerosis.

BACKGROUND: Studies have been fairly consistent in finding a relationship between social support and depression. However, little is known about the relationship between depression and social support in the context of treatment for depression. This study examined the effects of treatment for depression on social support among patients with multiple sclerosis (MS). METHOD: Sixty-three moderately depressed MS patients received 16 weeks of cognitive behaviour therapy (CBT), supportive expressive group psychotherapy (SEGP) or sertraline. Depression was measured using the Beck Depression Inventory and social support was measured using Arizona Social Support Interview Schedule. RESULTS: Treatment for depression was associated with significant increases in perceived social support, utilized social support and satisfaction with support, as well as reduction in need for emotional support. There were no significant changes in structural support or need for physical support. There were also no differences in change in social support across treatments. All changes in social support were fully explained by depression. Improvements in utilized social support and satisfaction with social support were fully mediated by improvements in depression. Baseline depression predicted improvements in perceived support and need for emotional support. CONCLUSIONS: These findings suggest that improvements in social support among MS patients during treatment for depression can be explained by depression. However, different domains of social support may be differentially sensitive to changes in depression.

Depression and depressive symptoms in rheumatoid arthritis patients: an analysis of their occurrence and determinants.

The objectives were to determine the differences in depressive symptoms and depression between rheumatoid arthritis (RA) and osteoarthritis (OA) patients, and to analyse the contribution of sociodemographic and clinical variables to depression in RA patients. The responses of 60 Egyptian RA patients and 40 patients with OA of the knees to the Symptom Checklist-90-R Depression subscale were compared. The proportions of patients from both groups confirmed by a psychiatric interview to be clinically depressed according to the DSM-III-R criteria were also compared. The contributions of sociodemographic and disease variables to depressive symptoms and clinical depression in RA patients were explored by multiple linear and logistic regression, respectively. RA patients showed significantly higher depression scores than OA patients (P = 0.001). The difference was unaffected by controlling for the effects of age, sex, disease duration and the sociodemographic covariates. A depressive disorder was clinically confirmed in 23% of RA patients and 10% of OA patients. The erythrocyte sedimentation rate (ESR), being unmarried and an urban residence were significant predictors of depressive symptoms (P < 0.05), while being unmarried (P < 0.05, OR = 2.1) and HAQ disability (P < 0.01, OR = 3.8) were significant predictors of clinical depression in RA patients. RA patients have significantly more depressive symptoms and tend to be more clinically depressed than OA patients. The contribution of some sociodemographic and clinical variables to depression in RA patients was modest, albeit significant.

Depression spectrum disease versus pure depressive disease. Clinical, personality, and course differences.

In a group of 191 women admitted to the University of Iowa Psychiatric Hospital for depression over a 45-year period and selected on the basis of alcoholism or antisocial personality, vs. depression, in a parent, 105 probands fit into the depression spectrum group (parental alcoholism or antisocial personality) and 86 into the pure depression group (parental depression). Few differences were found between the presenting clinical pictures (including precipitating factors) of the two groups; but depression spectrum patients and pure depressive patients showed study differences in the areas of personal problems and personality as well as course of illness. The depression spectrum patients were significantly less likely to have loss of interest in usual activities as a symptom at index admission. They were significantly more likely to have had a history of sexual problems, to have been divorced or separated before, to have been described as irritable, and to report having previously been depressed. They are nonetheless significantly more likely to recover completely and have no relapse of depression. The pure depression group were significantly more likely to have depressed sisters, and suicide was much more frequent in their ill parents. Thus, important personality and course differences separate depressive spectrum disease from pure depressive disease;

Comparative analysis of the performance of the Postpartum Depression Screening Scale with two other depression instruments.

BACKGROUND: Postpartum depression affects approximately 13% of mothers but up to 50% of all cases of this tragic illness can go undetected. OBJECTIVE: The purpose of this study was to compare the performance of a newly created instrument, the Postpartum Depression Screening Scale (PDSS), with the Edinburgh Postnatal Depression Scale (EPDS) and a general depression scale, the Beck Depression Inventory-II (BDI-II). METHOD: In this methodological design a total of 150 new mothers completed these three instruments in random order, followed immediately by a DSM-IV diagnostic interview. Using the LABROC I program, the areas under each of the instrument's Receiver Operator Characteristic (ROC) curves were compared to determine if they were significantly different. RESULTS: Eighteen (12%) of the women were diagnosed with major postpartum depression, 28 women (19%) with minor postpartum depression, and 104 women (69%) with no depression. Compared to the EPDS, the PDSS had a significantly larger area under the ROC curve when screening for major or minor postpartum depression. When using the published recommended cut-off scores for major depression for the three instruments, the PDSS achieved the highest combination of sensitivity, 94%, and specificity, 98%. When detecting women with major or minor postpartum depression, the PDSS again yielded the highest combination of sensitivity (91%) and specificity (72%) of the three instruments. The PDSS identified 17 (94%) of the women diagnosed with major postpartum depression, the EPDS identified 14 of these women (78%), and the BDI-II identified 10 of the 18 women (56%). CONCLUSION: If mothers identified as "most depressed" are substantially determined by the instrument used, the implications for both research and clinical practice are significant. Researchers and clinicians need to be aware of the differential sensitivity of depression instruments which, while supposedly measuring the same construct, are focused on different components of this mood disorder.

An observational analysis of behavior in depressed preschoolers: further validation of early-onset depression.

OBJECTIVE: To investigate whether higher levels of negative and lower levels of positive behaviors could be observed in a sample of depressed preschoolers. Support for the validity of preschool depression is now available; however, objective evidence of negative behaviors among depressed preschoolers is needed. METHOD: A structured observational parent-child interaction task was conducted. The behaviors of 152 preschoolers (ages 3.0-5.6) in three study groups (depressed, disruptive, and healthy) were examined with further analyses of depressed subgroups based on severity and comorbidity. RESULTS: Anhedonically depressed preschoolers emerged as demonstrating less enthusiasm, more avoidance, more noncompliance, and having a more negative overall experience than healthy controls. This more severe and proposed melancholic anhedonic subgroup also displayed less enthusiasm than nonanhedonically depressed preschoolers. Furthermore, the "pure" anhedonic depressed preschoolers without disruptive comorbidity emerged as the only depressed subgroup that was significantly distinguishable from healthy preschoolers. CONCLUSIONS: Findings provide the first objective evidence of more negative and fewer positive behaviors among depressed preschoolers. Notably, the finding that anhedonically depressed preschoolers demonstrated significantly less enthusiasm than those with nonanhedonic depression provides the first objective evidence of the manifestation of anhedonia, a key sign of preschool depression. The implications of the finding that the "pure" anhedonic depressed subgroup without disruptive comorbidity was most distinguishable from comparison groups are explored.

The community initiative on depression: report from a multiphase work site depression intervention.

OBJECTIVE: We sought to further understand depression, a common, disabling condition with considerable ramifications for the workplace, including higher costs, absenteeism, and reduced work performance. METHODS: A multidisciplinary health care coalition recently implemented a multiphase workplace depression initiative in Kansas City. We report results from its first phase, a 22-item, self-administered survey of depression knowledge and attitudes among employees of 13 large, local work sites. RESULTS: There were 6,399/38,945 respondents (16% response rate). Most respondents (>90%) appropriately recognized the signs and symptoms of depression. A minority (29%) would feel comfortable discussing depression with their supervisor. Sixty-two percent knew how to access company resources for depression care. CONCLUSIONS: Employees were knowledgeable about depression but were less aware of employee-assistance programs for depression care. These findings support increased attempts to raise the awareness of depression and promote of help-seeking behavior in the workplace. CLINICAL SIGNIFICANCE: Depression is a prevalent illness with risk for many deleterious outcomes if under-recognized or undertreated. Depression is a leading cause of work-related disability worldwide. Most people with depression are employed (an estimated 68%). Recognizing and initiating depression care in the workplace will facilitate depression treatment in clinical settings.

Do depressed older adults who attribute depression to "old age" believe it is important to seek care?

OBJECTIVE: To determine whether depressed older adults who attribute becoming depressed to "old age" rather than illness are more likely to believe it is not important to seek treatment for depression. DESIGN: Cross-sectional mailed survey. SETTING: Academically affiliated primary care physicians' network. PARTICIPANTS: Surveys were mailed to 588 patients age > or =65 years who were randomly identified from patient lists of 20 physicians. Surveys were returned by 429 patients (73%). Patients were eligible for this study if they scored > or =2 points on the 5-item Geriatric Depression Scale (n = 94) and were not missing key variables (final n = 90). MEASUREMENTS AND MAIN RESULTS: Of the 90 depressed patients, 48 (53%) believed that feeling depressed was very important to discuss with a doctor. In unadjusted analysis, older adults who did not believe it is very important to discuss feeling depressed with a doctor were more likely to attribute becoming depressed to aging (41% vs 17%; P =.012). In a logistic regression model adjusting for sociodemographic characteristics, number of impairments in basic and instrumental activities of daily living, medical comorbidity, and physical (PCS-12) and mental (MCS-12) component summary scores from the Medical Outcomes Study Short-Form-12, depressed older adults who attributed depression to aging had a 4.3 times greater odds than those who attributed depression to illness to not believe it is very important to discuss depression with a doctor (odds ratio [OR], 4.3; 95% confidence interval [CI], 1.3 to 14.5). CONCLUSIONS: Among older persons with depression, attributing feeling depressed to old age may be an important barrier to care seeking.

Screening for depression in chronic hemodialysis patients: comparison of the Beck Depression Inventory, primary nurse, and nephrology team.

Depression in patients with end-state renal disease (ESRD) is both underdiagnosed and treated, which may contribute to an increase in morbidity and mortality. Efforts aimed at screening, diagnosing, and treating depression could potentially modify outcomes in this population. The purpose of this study was to compare the prevalence of depression, as measured by the Beck Depression Inventory (BDI-II), the primary nurse, and nephrology team, among a cohort of patients receiving chronic hemodialysis (HD). A secondary objective was to identify patient variables associated with depression. Patients were screened for depression at the same time point, using the BDI-II, the primary nurse and the nephrology team. Depression was defined as a BDI-II score > or =14. Agreement between the BDI-II score, nurse, and nephrology team assessment of depression was compared using a kappa score and receiver-operating characteristic (ROC) curves were generated. One hundred and twenty-four of an eligible 154 patients completed the study. Depression as measured by a BDI-II> or =14, the nurse and the team was diagnosed in 38.7%, 41.9%, and 24.2% of patients, respectively. With the BDI-II as the gold standard, the nurses' diagnosis of depression had an agreement of 74.6% vs. only 24.2% agreement with the nephrology team. A previous history of malignancy was the only variable associated with the diagnosis of depression. Depression is common among patients on HD, supporting the need for a routine depression-screening program. The primary dialysis nurse is in a key position to identify patients with depression and should be considered as an integral part of the nephrology team.

Are depressive persons capable of describing changes in their reactions without being able to explain them? A proof of a cybernetic hypothesis of depression.

BACKGROUND: Many studies on the autobiographical memory and the explanation of reasons for success and failure proved that persons suffering from major depression tend to overgeneralize. This study examines the hypothesis that changes of reactions caused by a depressive disorder can be described by the affected persons but not explained. SAMPLE AND METHODS: Persons suffering from major depression and persons with posttraumatic stress disorder or disturbance of accommodation with depressive mood (= reactive form of a depressive disorder) were presented with a list of modalities (behaviour, emotional and physical reactions) characteristic for depression. They were asked to identify modalities applicable to them and to describe and explain them. Their responses were analysed using a content analysis and assigned to the categories description and explanation. RESULTS: Persons with a major depression tended to use explanations or evaluations rather than descriptions for their depression-related modalities. Those persons suffering from a reactive form of depressive disorder tended to prefer evaluations. CONCLUSION: These results support the assumption that states of depression cause general descriptions of depression-relevant behaviour. The specific characteristics that have been perceived confirm the general concepts, which however make the patient prone to the respective selective perceptions. Persons suffering from a reactive form of depressive mood cannot be assumed to have this tendency of self-affirmation. Their depressive state may be maintained by perseverating general pessimistic schemes. LIMITATIONS: It must however be conceded that it was not possible to control the physical comorbidity methodically and to take its effects into consideration, even though only persons without serious illnesses were included in the samples. This study did not verify whether other clinical groups, like patients suffering from anxiety, show the same patterns of explaining and describing their problems. It should furthermore be reviewed how other actions, e.g. positive ones, are represented by depressive persons.

Increased recognition of depression in primary care. Comparison between primary-care physician and ICD-10 diagnosis of depression.

BACKGROUND: Underrecognition and undertreatment of depression in primary care has been regarded as a major public health problem. In contrast, some studies found that among patients labeled as depressed by primary-care physicians (PCPs), a relevant proportion do not satisfy international diagnostic criteria for depression. The aims of this study are: (1) to assess disparity between PCP diagnosis and research diagnosis of depression; (2) to compare antidepressant treatment in concordant and discordant cases of depression. METHODS: Data are gathered from a national survey on depressive disorders in primary care, conducted with the collaboration of 191 PCPs. Three hundred and sixty-one PCP patients were evaluated, and their psychiatric diagnosis was established by the 'unaided' PCPs and by using a research interview for depression. RESULTS: PCPs recognized 79.4% of cases of depression and prescribed antidepressants to 40.9% of them. Yet, 45.0% of patients labeled as depressed by the PCPs were not cases of depression according to ICD-10 criteria; 26.9% of false-positive cases received an antidepressant. Globally, 35% of antidepressants for 'depression' were prescribed to false-positive cases. CONCLUSIONS: Underrecognition and undertreatment of depression in primary care seem to be less alarming. Conversely, PCP diagnoses of depression appear to be more inclusive than psychiatric diagnostic criteria. A possible consequence of this apparently more inclusive diagnostic threshold may be an excessive use of antidepressants. These changes require a corresponding change in research, toward efficacy and safety of the treatment of milder cases, and in education, toward the distinction between the management of mild and severe cases of depression.

Ten-year stability of depressive personality disorder in depressed outpatients.

OBJECTIVE: The purpose of this study was to examine the long-term stability of depressive personality disorder. METHOD: The subjects included 142 outpatients with axis I depressive disorders at study entry; 73 had depressive personality disorder. The patients were assessed by using semistructured diagnostic interviews at baseline and in four follow-up evaluations at 2.5-year intervals over 10.0 years. Follow-up data were available for 127 (89.4%) of the patients. RESULTS: The 10.0-year stability of the diagnoses of depressive personality disorder was fair, and the rate of depressive personality disorder declined over time. The dimensional score was moderately stable over 10.0 years. Growth curve analyses revealed a sharp decline in the level of depressive personality disorder traits between the baseline and 2.5-year assessments, followed by a gradual linear decrease. Reductions in depressive personality disorder traits were associated with remission of the axis I depressive disorders. Finally, depressive personality disorder at baseline predicted the trajectory of depressive symptoms over time in patients with dysthymic disorder. CONCLUSIONS: Depressive personality disorder is moderately stable, particularly when assessed with a dimensional approach. However, the diagnosis rate and traits of depressive personality disorder tend to decline over time. The degree of stability for depressive personality disorder is comparable to that for the axis II disorders in the main text of DSM-IV. Finally, depressive personality disorder has prognostic implications for the course of axis I mood disorders, such as dysthymic disorder.
