Determinants of functional disability and social adjustment in major depressive disorder: a prospective study.

We examined prospectively factors influencing social and occupational disability and social adjustment among patients with major depressive disorder. The Vantaa Depression Study comprises a cohort of psychiatric inpatients and outpatients with major depressive disorder in the city of Vantaa, Finland. We prospectively interviewed 193 of 269 (72%) patients both 6 and 18 months after baseline. Axis I and II diagnoses were assessed via semistructured WHO Schedules for Clinical Assessment in Neuropsychiatry 2.0 and SCID-II interviews. Global disability and social and work adjustment were assessed. Patients' functional disability and social adjustment were alleviated concurrently with recovery from depression during the follow-up. The current level of functioning and social adjustment of a patient with depression was predicted by severity of depression, recurrence before baseline and during follow-up, lack of full remission, and time spent depressed. Comorbid psychiatric disorders, personality traits (neuroticism), and perceived social support had significant influence.

Prospective study of risk factors for attempted suicide among patients with DSM-IV major depressive disorder.

BACKGROUND: There are few prospective studies on risk factors for attempted suicide among psychiatric out- and in-patients with major depressive disorder. AIMS: To investigate risk factors for attempted suicide among psychiatric out- and in-patients with major depressive disorder in the city of Vantaa, Finland. METHOD: The Vantaa Depression Study included 269 patients with DSM-IV major depressive disorder diagnosed using semistructured interviews and followed up at 6- and 18-month interviews with a life chart. RESULTS: During the 18-month followup, 8% of the patients attempted suicide. The relative risk of an attempt was 2.50 during partial remission and 7.54 during a major depressive episode, compared with full remission (P 0.001). Numerous factors were associated with this risk, but lacking a partner, previous suicide attempts and total time spent in major depressive episodes were the most robust predictors. CONCLUSIONS: Suicide attempts among patients with major depressive disorder are strongly associated with the presence and severity of depressive symptoms and predicted by lack of partner, previous suicide attempts and time spent in depression. Reducing the time spent depressed is a credible preventive measure.

Functional and work disability in major depressive disorder.

We examined factors related to social and occupational disability, social adjustment, and work disability among patients with major depressive disorder (MDD), the dominant mental disorder causing functional and work disability. The Vantaa Depression Study comprises a cohort of 269 psychiatric inpatients and outpatients with MDD in the city of Vantaa, Finland. Axis I and II diagnoses were assessed via semistructured WHO Schedules for Clinical Assessment in Neuropsychiatry Version 2.0 and Structured Clinical Interview for DSM-III-R personality disorders interviews. Global disability, social and work adjustment, and being at work or on sick leave were assessed. The most important factors associated with level of social, functional, and work disability were severity and recurrence of depression, but older age and current Axis I and II comorbidity also significantly contributed. Of those employed, almost half (43%) were on sick leave. The most pervasive factors explaining level of functional and work disability among patients with MDD were severity and recurrence of depression. However, older age and comorbidity also contributed.

Continuity is the main challenge in treating major depressive disorder in psychiatric care.

OBJECTIVE: Several evidence-based treatment guidelines for major depressive disorder (MDD) have been published. However, little is known about how recommendations for treatment are adhered to by patients in current usual psychiatric practice. METHOD: The Vantaa Depression Study is a prospective, naturalistic cohort study of 269 psychiatric patients with a new episode of DSM-IV MDD who were interviewed with the Schedules for Clinical Assessment in Neuropsychiatry and Structured Clinical Interview for DSM-III-R Personality Disorders between February 1, 1997, and May 31, 1998, and again at 6 and 18 months. Treatments provided, as well as adherence to and attitudes toward both antidepressants and psychotherapeutic support/psychotherapy, were investigated among the 198 unipolar patients followed for 18 months. RESULTS: Most depression patients (88%) received antidepressants in the early acute phase, but about half (49%) terminated treatment prematurely. This premature termination was associated with worse outcome of major depressive episodes, and with negative attitudes, mainly explained by fear of dependence on or side effects of antidepressants. Nearly all patients (98%) received some psychosocial treatment in the acute phase; about one fifth (16%) had weekly psychotherapy during the follow-up. About a quarter of patients admitted nonadherence to ongoing treatments. CONCLUSION: Problems of psychiatric care seem most related to continuity of treatment. While adequate treatments are provided in the early acute phase, antidepressants are terminated too soon in about half of patients, often following their autonomous decisions. From a secondary and tertiary preventive point of view, improving continuity of treatment would appear a crucial task for improving the outcome of psychiatric patients with MDD.

Severity and comorbidity predict episode duration and recurrence of DSM-IV major depressive disorder.

BACKGROUND: Information on the naturalistic outcome of major depressive disorder (MDD) is important in developing rational clinical practices. The aim of this study was to determine the outcome of MDD in a modern secondary-level psychiatric setting and the influence of comorbidity plus psychosocial factors on the outcome of MDD. METHOD: The Vantaa Depression Study is a prospective, naturalistic cohort study of 269 secondary-level care psychiatric outpatients and inpatients diagnosed with a new episode of DSM-IV MDD. Patients were initially interviewed to determine the presence of MDD using the World Health Organization Schedule for Clinical Assessment in Neuropsychiatry and to assess Axis II diagnoses using the Structured Clinical Interview for DSM-III-R personality disorders between February 1, 1997, and May 31, 1998, and were interviewed again at 6 months and 18 months. The exact duration of the index episode and the timing of relapses/recurrences were examined using a life chart. RESULTS: The median length of time that patients met full criteria for a major depressive episode was 1.5 (95% CL = 1.3 to 1.7) months, and the median time to full remission was 8.1 (95% CL = 5.2 to 11.0) months after entry. During the follow-up, 38% of patients had a recurrence. Although numerous factors predict outcome of MDD to some extent, severity of depression and current comorbidity were the 2 most important predictors of longer episode duration and recurrence. CONCLUSION: The course of MDD in modern psychiatric settings remains unfavorable. Any estimates of duration of depressive episodes and rates of recurrence are likely to be dependent on the severity of depression and level of comorbidity. At least among a population of mostly outpatients with MDD in medium-term follow-up, severity of depression and comorbidity appear to be more useful predictors of recurrence than does the number of prior episodes. These factors should influence clinical decision-making regarding the need for maintenance therapy.

Life events, social support, and onset of major depressive episode in Finnish patients.

We investigated differences in life events and social support between subgroups of depressed patients and the distribution of life events in phases preceding or during depression. In the Vantaa Depression Study, 269 psychiatric patients with DSM-IV major depressive disorder were diagnosed with Schedule for Clinical Assessment in Neuropsychiatry, Version 2.0, and Structured Clinical Interview for DSM-III-R personality disorders (SCID-II). Life events during the 12 months preceding the interview were investigated with the Interview for Recent Life Events, and social support with the Interview Measure of Social Relationships and the Perceived Social Support Scale-Revised. Nearly all patients (91%) reported life events, on average 4.1 per preceding year. No major differences between sociodemographic or clinical subgroups were found; the frequency of events was somewhat greater among the younger subjects, whereas those with comorbid alcoholism or personality disorders perceived less social support. Although events were distributed evenly between the time preceding depression, the prodromal phase, and the index major depressive episode, two thirds of the patients attributed their depression to some event. Despite clinical and sociodemographic heterogeneity, patients with major depressive disorder are fairly homogeneous in terms of life events during the preceding year. Events do not cluster in any particular phase of the progression to an episode.

Suicidal ideation and attempts among psychiatric patients with major depressive disorder.

BACKGROUND: Few studies have investigated risk factors for suicidal ideation and attempts, or possible variations in them, among representative samples of psychiatric patients with major depressive disorder. METHOD: As part of the Vantaa Depression Study in Vantaa, Finland, 269 patients with DSM-IV major depressive disorder (MDD), diagnosed by interview using semistructured World Health Organization Schedules for Clinical Assessment in Neuropsychiatry, version 2.0, and Structured Clinical Interview for DSM-III-R Personality Disorders, were thoroughly investigated. Information was gathered on patients' levels of depression, anxiety, hopelessness, perceived social support, social and occupational functioning, and alcohol use. Suicidal behavior was assessed by interviews, including the Scale for Suicidal Ideation, and by information from psychiatric records. Data were gathered from Feb. 1, 1997, to May 31, 1998. RESULTS: During the current MDD episode, 58% of all patients had experienced suicidal ideation; among the 15% of the total who had attempted suicide, almost all (95%) had also had suicidal ideation. In nominal regression models predicting suicidal ideation, hopelessness, alcohol dependence or abuse, low level of social and occupational functioning, and poor perceived social support were found to be significant (p < .05) independent risk factors. High severity of depression and current alcohol dependence or abuse in particular, but also younger age and low level of social and occupational functioning, predicted suicide attempt. CONCLUSION: Suicidal ideation is prevalent and appears to be a precondition for suicide attempts among psychiatric patients with MDD. The risk factors for suicidal ideation and attempts locate in several clinical and psychosocial domains. While these risk factors largely overlap, the overall level of psychopathology of suicide attempters is higher compared with that in patients with ideation, and substance use disorders and severity of depression may be of particular importance in predicting suicide attempts.

Current comorbidity of psychiatric disorders among DSM-IV major depressive disorder patients in psychiatric care in the Vantaa Depression Study.

BACKGROUND: While numerous studies have documented the high comorbidity of major depressive disorder (MDD) with individual mental disorders, no published study has reported overall current comorbidity with all Axis I and II disorders among psychiatric patients with MDD, nor systematically investigated variations in current comorbidity by sociodemographic factors, inpatient versus outpatient status, and number of lifetime depressive episodes. METHOD: Psychiatric outpatients and inpatients in Vantaa, Finland, were prospectively screened for an episode of DSM-IV MDD, and 269 patients with a new episode of MDD were enrolled in the Vantaa Depression MDD Cohort Study. Axis I and II comorbidity was assessed via semistructured Schedules for Clinical Assessment in Neuropsychiatry, version 2.0, and Structured Clinical Interview for DSM-II-R personality disorders interviews. RESULTS: The great majority (79%) of patients with MDD suffered from 1 or more current comorbid mental disorders, including anxiety disorder (57%), alcohol use disorder (25%), and personality disorder (44%). Several anxiety disorders were associated with specific Axis II clusters, and panic disorder with agoraphobia was associated with inpatient status. The prevalence of personality disorders varied with inpatient versus outpatient status, number of lifetime depressive episodes, and type of residential area, and the prevalence of substance use disorders varied with gender and inpatient versus outpatient status. CONCLUSION: Most psychiatric patients with MDD have at least 1 current comorbid disorder. Comorbid disorders are associated not only with other comorbid disorders, but also with sociodemographic factors, inpatient versus outpatient status, and lifetime number of depressive episodes. The influence of these variations on current comorbidity patterns among MDD patients needs to be taken account of in treatment facilities.
