Temporal course of symptoms and social functioning in relapsing schizophrenics: a 6-year follow-up

As a part of the Copenhagen High Risk project, a 6 year follow-up of relapses after first hospitalisation of 67 schizophrenic women was performed. Four dimensions of psychopathology were examined: positive symptoms, negative symptoms, formal thought disorder and depressive symptoms. Each symptom group was its own best predictor over time. Only depressive symptoms diminished significantly at a relapse 6 years after first hospitalisation. Broadly defined subtyping of schizophrenia into paranoid and non-paranoid, retained stability over a 6 year period. It is concluded that there is a stability of psychopathology across onset episodes and relapses.     

Partial remission in major depression: a two-phase, 12-month prospective study

We conducted an interview-based survey to predict the clinical course of major depressive disorder during a follow-up period of 12 months. Altogether 86 patients were investigated. A SCID I interview for DSM-III-R axis-I diagnosis was conducted at baseline and a SCID II interview for personality disorders at the 6-month follow-up. Beck Depression Inventory scores indicated the level of depression and were compiled at baseline and at 6 and 12 months. A BDI score between 9 and 14 was considered to indicate partial remission, and score of 0-8 indicated remission. At the 6-month assessment 33% of the patients had remission, 20% were in partial remission, and 47% were in the depressive phase. Older age, personality disorder, and alexithymia were associated with poor response at 6 months. At 12 months 37% had remission, 28% were in partial remission, and 35% were still in the depressive phase. Treatment at the early stage should be effective enough to achieve remission. If the response is not satisfactory within 6 months, a renewed search should be conducted for factors hindering recovery. Comorbid personality disorder is the main factor predicting a poor short-term response in major depressive disorder.     

A 3-year follow-up study of psychosocial functioning and general symptoms in settled refugees

OBJECTIVE: Few community studies have addressed the longitudinal course of post-traumatic stress disorder (PTSD) in traumatized refugees in early resettlement. This longitudinal study investigated changes from the first (T1) to the second interview (T2), 3 years later. The relationship between traumatic exposures and psychosocial factors/psychological symptom load were examined. METHOD: Local health professionals performed the interviews, using rating scales and a structured questionnaire. A total of 240 (52%) refugees attended. RESULTS: Unchanged Hopkins Symptom Checklist-25 and increase in Harvard Trauma Questionnaire and post-traumatic stress symptoms-16 between T1 and T2 were found, indicating the severity and chronicity of problems. Mean post-traumatic stress score was 15% above cut-off. Severe life-threatening trauma and present life in exile with unemployment and unresolved family reunion were risk factors. CONCLUSION: Early diagnostic interview should be followed by targeted approach. Pinpointing those in need of specialist services is essential. An interdisciplinary approach is necessary in this work.     

Alexithymia and depression: A 1-year follow-up study in outpatients with major depression

Objective: To examine the changes in alexithymic features and depressive and other psychological distress symptoms during a 1-year follow-up among patients with major depression. Methods: The study population comprised 120 outpatients suffering from major depression. Diagnosis was made with Structured Clinical Interview (SCID-I) for DSM-III-R. The severity of depression was evaluated with the 17-item Hamilton Rating Scale for Depression (HAM-D), and self-reported depression with the Beck Depression Inventory (BDI-21). Alexithymic features were assessed with the Twenty-Item Toronto Alexithymia Scale (TAS-20). Self-reported psychological distress symptoms were evaluated with the Brief Symptom Inventory (BSI). Results: Measures of depression and distress were significantly lower at the follow-up than at the baseline, while the total TAS-20 scores did not change significantly during the follow-up. A closer examination revealed that various TAS-20 factors behaved differently. Changes in Factors 1 and 2 were associated with changes in mood, whereas those in Factor 3 were not. Additionally, recovery from depression was associated with decrease in alexithymic features. Conclusion: Difficulties in identifying and in describing feelings are associated with changes in mood, while externally oriented thinking is not.     

Partial remission in major depression: A two-phase, 12-month prospective study

The movements were examined in accordance with the Comprehensive Body Examination. The study objects were 99 persons: 17 pain syndrome patients (PSP group), 27 psychotic patients (PP group), 4 non-psychotic patients (NPP group), and a comparison group consisting of 51 students and staff members (SS group). On the basis of factor analysis three subscales were made: 1) Resistance to Passive Movements (RPM), with nine items, 2) Assistance to Passive Movements (APM), with six items, and 3) Motor Disturbances (MD), with three items. The internal consistency of the subscales was high (Chronbach's alpha, 0.81-0.96), and the intercorrelation low to moderate. The RPM subscale distinguished significantly between the SS group and both patient groups; the APM and MD subscales distinguished between the SS group and the PP group. The MD subscale also distinguished between patients taking drugs and those who did not, but there was no difference between patients without medication and the SS group.     

Functional status and return to work in people with major depression: a 3-year national follow-up study

Purpose

Major depressive disorder (MDD) affects a person’s function of daily activities, including work participation. Such functional impairments often persist even when other symptoms of MDD are remitted. Increasing evidence highlights the health-promoting effects of returning to work (RTW) in various diseases. However, limited data are available regarding the impact of return to work on functional recovery in MDD. We explored the association between RTW and functional improvements in people with MDD using a large nationally representative database and a 3-year follow-up.

Methods

Data of people with an MDD diagnosis were selected from the Taiwan Data Bank of Persons with disability for the period between July 11, 2012, and October 31, 2018. We included 4038 adults aged 18–64 years. The World Health Organization Disability Assessment Schedule 2.0 was used for functional assessment. The association between RTW and functional improvements was investigated using a multivariable regression analysis adjusted for confounding variables.

Results

Women aged ≥ 45 years with a lower education level were vulnerable to prolonged unemployment. RTW was significantly associated with better functional improvements in cognition, mobility, self-care, getting along, life activity, and participation than unemployment.

Conclusions

RTW was positively associated with functional improvements in patients with MDD. A referral system targeting re-employment may be suggested during MDD treatment, especially for individuals at risk of prolonged unemployment.

     

Long-lasting cognitive impairment in unipolar major depression: a 6-month follow-up study

The aim of the study was to investigate cognitive impairment in major depression both acutely and after 6 months. All patients were investigated within a neurocognitive experimental setting at two testing sessions: at inclusion and after 6 months. Automatic and effortful information processing was investigated with a visual search paradigm. Twenty-one patients with recurrent major depression according to DSM-IV and a Hamilton Depression Rating Scale score >18 were included in the study. Healthy subjects, matched for age and gender, were used as a control group. The results showed that the depressed patients performed equal to the control group on trials requiring automatic information processing at both sessions. However, the patients were impaired compared to the control group on trials requiring effortful information processing, also at both sessions. The depressed patients showed no improvement in cognitive performance from test 1 to test 2. The results indicate that the depressed patients had an impaired performance for effortful, but not automatic, visual search performance, and that the impairment remained after 6 months, despite significant improvement in their depression scores.     

Psychological functioning and quality of life following bone marrow transplantation: a 3-year follow-up study

OBJECTIVE: To assess changes in quality of life and psychological distress following bone marrow transplantation (BMT) and variables related to this change. METHODS: One hundred twenty-five consecutive patients who underwent bone marrow transplantation (BMT) at the Leiden University Medical Centre between 1987 and 1992 filled in questionnaires measuring quality of life, functional limitations, psychological distress, anxiety, depression, self-esteem, and health locus of control. Measurements were taken before the BMT; 1 month after discharge; and 6 months, 1 year, and 3 years after the BMT. RESULTS: Three years after BMT, a quarter of the patients continued to experience serious functional limitations. Thirteen percent of the patients scored >4 on the General Health Questionnaire (GHQ-12), a percentage comparable to general population prevalence. Quality of life was reported to be good to excellent by almost 90% of the patients at three years. Changes in quality of life could be explained entirely by changes in functional limitations and somatic symptoms. Changes in psychological distress were also related to these measures, and furthermore to baseline psychological functioning. CONCLUSION: Although patients were doing well three years after BMT, there was a group of patients needing help. In interventions special attention should be given to patients with ongoing psychological problems. Emphasis should be on coping with physical limitations.     

Comorbid personality disorder predicts suicide after major depression: a 10-year follow-up

OBJECTIVE: To identify psychopathological predictors for suicide in a population of major depressed Diagnostic Statistical Manual-III (DSM-III) in-patients. METHOD: A total of 210 previous participants in multicentre antidepressant drug trials, carried out in a randomized double-blind design, were followed prospectively through a maximum of 10 years. Patients with a drug or alcohol abuse were excluded. The association between suicide and the pretreatment psychopathological profile was analysed using survival statistics. RESULTS: The suicide rate for non-melancholic depressed patients was significantly higher than for melancholic depressed patients. Comorbid personality disorder was independently associated with an increased suicide rate [relative hazard 3.41(CI: 1.15-10.10)]. CONCLUSION: The study indicates that the non-melancholic aspect of depression, and especially comorbid personality disorder, is associated with an increased suicidal vulnerability.     

Definitions of recovery and outcomes of major depression: results from a 10-year follow-up

Objective: Consensus operational definitions for symptomatic remission and recovery of a major depressive episode have been proposed but only irregularly followed. Method: We examined the predictive validity of different definitions of recovery in a multi‐center 10‐year follow‐up study of an inception cohort of untreated unipolar major depressive episodes (n = 95). Time to recovery and time to recurrence after recovery were estimated by Kaplan–Meier survival analyses for alternative definitions requiring 2, 4, 6 or 12 months of remission to declare recovery. Results: The median time to recovery was 3.0, 4.0, 4.0 and 12.0 months respectively. The index episode lasted longer than 24 months in 9.4%, 9.2%, 12.6% and 24.5%. The median time to subthreshold recurrence was 16.0, 32.0, 42.0 and 74.0 months. Conclusion: Either 4‐ or 6‐month duration of remission defined a change point before which the episode was continuous and after which the recurrence was reasonably unlikely.     

Repeated use of psychiatric emergency out-patient services among new patients: a 3-year follow-up study

The aim of this study was to examine repeated use of psychiatric emergency out-patient services during the second and third years after the first contact. A 1-year treated incidence cohort of 537 new patients was studied in the Department of Psychiatry in Oulu, Finland. Repeat users were defined as patients belonging to the upper 10th percentile of the emergency out-patient contacts. The median of emergency out-patient contacts among repeaters was 4. The repeaters constituted 8% of the cohort and they used 65% of the cohort's emergency contacts. They were more likely to be male and living alone, and they tended to have more serious diagnoses than non-repeaters. Having hospital admissions, planned out-patient contacts and repeated emergency out-patient contacts also during the first year of follow-up was associated with an increased probability of repeatedly using emergency services during the second and third years. Living alone and having hospital admissions during the follow-up period were associated with being a continuous repeat visitor during the whole follow-up period. It is concluded that the extended repeated use of emergency services is associated with inadequate social support and serious psychiatric problems.     

Verbal learning and memory in depression: a 9-year follow-up study

Memory impairment is often associated with depression. However, the literature is not uniform whether such impairment constitutes state and/or trait characteristics. One-hundred-and-twelve clinically depressed (CDs), previously depressed (PDs), and never depressed (NDs) subjects (T2 diagnostic status),were assessed with the California Verbal Learning Test (CVLT) at T1 and re-assessed 9 years later with the revised version, CVLT-II. At T1 no deficit in verbal memory between CDs and PDs compared to NDs was found, in which the majority of the subjects were younger adults. At follow-up the majority of CDs and PDs had suffered one or several recurrent depressive episodes. Repeated-measures analysis of variance showed, in particular and irrespective of group, a significant decline in recall measures over time. CDs, PDs and NDs showed the same pattern of verbal memory performance over time with the exception of Short Delayed Free Recall, in which CDs and PDs showed a significant decline in performance at follow-up compared to NDs. Likewise, subjects with recurrent depression performed comparable to subjects with a single episode over the course of follow-up. Our results suggest that individuals with mild to moderate unipolar depression may not be significantly affected by verbal memory impairments over the long-term course. The comparability of the versions of the CVLT is addressed.     

Time zone change and major psychiatric morbidity: the results of a 6-year study in Jerusalem.

Psychiatric morbidity among foreign tourists is usually connected to external factors such as unfamiliar surroundings, language problems, and special religious experiences, as well as biological factors such as dyschronism of circadian rhythms. Long-range flights through several time zones are typically followed by symptoms of jet lag such as fatigue, severe sleep schedule disturbance, impairment of cognitive functions, and even mild depression. Jet lag is generally attributed to a conflict between external time cues and internal biological rhythms. This study examined the possible association between jet lag and psychiatric morbidity among long-distance travelers hospitalized in the Jerusalem Mental Health Center, Kfar Shaul Hospital between 1993 and 1998. This was a prospective open-label study. Patients (n = 152) were divided into two groups based on the number of time zones crossed in the flight to Israel: group I, seven time zones or more (n = 81); and group II, three time zones or less (n = 71). The direction of flight was mainly eastbound. After controlling the two groups for demographic and religious background, past psychiatric history, and diagnosis on admission (P > 0.1, Fisher's exact test), the possible association between jet lag and psychotic or major affective disorder was evaluated according to the following criteria: (1) absence of major mental problems before the flight or good remission of an existing disorder 1 year or more before flight; and (2) the appearance of psychotic or major affective syndromes during the first 7 days after landing. The number of first psychotic/major affective episodes in both groups presumed as associated with jet lag was found similar (P =.5), whereas the number of relapses conjoint with jet lag in the seven or more time zone group was significantly higher (P =.04). The results suggest that the dyschronism of circadian rhythms and jet lag possibly play a role in the exacerbation of major psychiatric disorders.     

Pretreatment clinical and psychosocial predictors of remission from depression after short-term psychodynamic psychotherapy and solution-focused therapy: a 1-year follow-up study

Abstract

The mutual importance of different predictors of remission was studied in 163 outpatients with depression receiving either short-term psychodynamic psychotherapy or solution-focused therapy. After a 1-year follow-up, the percentage of remission significantly varied between sociodemographic subgroups and was dependent on severity of symptoms, personality disorder, and psychosocial factors but not on psychiatric history, previous psychiatric treatment, or type of therapy received. Simultaneous study showed that the most significant predictors were sense of coherence (based on Sense of Coherence Scale [SOCS]), symptom severity (based on Symptom Checklist-90 [SCL-90] Global Severity Index [GSI]), and education. The relative risks of remission between the lowest and highest quartiles of SOCS and SCL-90 GSI were 0.06 and 0.22 (95% confidence intervals = 0.01–0.35 and 0.05–0.97), respectively. In conclusion, several background factors, especially sense of coherence, predict remission.     

Instability of symptoms in recurrent major depression: a prospective study

OBJECTIVE: Recurrent episodes of major depressive disorder are reported to have similar or stable characteristics across episodes. However, symptoms appear to be moderately stable only in consecutive depressive episodes or if episode severity is considered. The authors prospectively studied major depressive episodes occurring within 2 years to determine whether symptoms in the second episode could be predicted on the basis of symptoms in the first. METHOD: Inpatients (N=78) with major depressive disorder were rated with the Hamilton Depression Rating Scale during two separate episodes. Patients had a baseline assessment at index hospitalization and follow-up visits at 3, 12, and 24 months after discharge. Information regarding the presence of a major depressive episode, its duration, and its severity was documented. Baseline and follow-up data were analyzed by using Pearson correlations with and without adjustments for severity of depression. RESULTS: Subtype of depression appeared not to be stable. The most robust, although still weak, correlations across episodes were for anxiety and suicidal behavior. Only modest correlations were identified for a few depressive symptoms. CONCLUSIONS: The lack of robust consistency of symptoms or depressive subtype across episodes is striking given the requirement of five of nine predetermined symptoms for depression, increasing the chances of finding an association. These findings suggest that there is a superfamily of mood disorders with pleomorphic manifestations across major depressive episodes within individual patients with unipolar depression.
