Predicting hospital discharge status for patients with schizophrenia, schizoaffective disorder, borderline personality disorder, and unipolar affective disorder

The empiric literature reports few distinctive features among patients discharged against medical advice (AMA) or absent without leave and regularly discharged inpatients. Interactive relationships between predictors of discharge status and diagnosis have not been studied, however. This study used discriminant function analyses to test for predictors of discharge with medical advice, AMA, and by transfer for inpatients with schizophrenia (N = 132), schizoaffective disorder (N = 61), borderline personality disorder (N = 69), and unipolar affective disorder (N = 42) from a follow-up study. Results showed that indexes of chronic psychosis predicted transfer for all diagnoses. Angry, impulsive behavior and unstable relationships predicted AMA discharge in all but the unipolar patients. For the latter, being married was most powerfully associated with AMA status.     

Outcome of schizoaffective disorder at two long-term follow-ups: comparisons with outcome of schizophrenia and affective disorders

OBJECTIVE: This research assessed whether the outcome of schizoaffective disorder is more similar to that of schizophrenia or that of affective disorders. METHOD: The authors conducted a prospective follow-up study of 101 schizoaffective, schizophrenic, bipolar manic, and depressed patients assessed at three times: during hospitalization and 2 and 4-5 years later. The follow-up test battery involved detailed assessment of social functioning, work performance, symptoms, posthospital treatment, and rehospitalization. RESULTS: Outcome for schizoaffective patients 4-5 years after hospitalization differed significantly from that for patients with unipolar depression. However, the differences between schizoaffective and bipolar manic patients were more equivocal. Unlike the patients with bipolar disorder, only a limited number of patients with schizoaffective disorder showed complete recovery in all areas throughout the year preceding the 2-year follow-up and the year preceding the 4- to 5-year follow-up. The differences in outcome between schizoaffective and schizophrenic patients were also mixed. These two groups showed some similarities in outcome, but there were fewer schizoaffective than schizophrenic patients with uniformly poor outcome in all areas. CONCLUSIONS: Overall, schizoaffective patients showed some similarities to both schizophrenic and bipolar manic patients. Schizoaffective patients had somewhat better overall posthospital functioning than patients with schizophrenia, somewhat poorer functioning than bipolar manic patients, and significantly poorer functioning than patients with unipolar depression. The data suggest that when mood-incongruent, schizophrenic-like psychotic symptoms are present in the acute phase, they predict considerable difficulty in outcome, even when affective syndromes are also present, as in schizoaffective disorder. It is likely that schizoaffective disorder is not just a simple variety of affective disorder.     

Implications of long-term outcome research for the management of patients with borderline personality disorder

Fifteen- and 27-year follow-up studies of patients with borderline personality disorder show that most of them no longer meet full criteria for the disorder by age 40, and that even more show improvement by age 50. The mechanisms behind remission could include maturation, social learning, and the avoidance of conflictual intimacy. Affective instability is slower to change than impulsivity. Suicide rates in patients with this disorder are close to 10%, with most completions occurring late in the course of illness; early mortality from all causes exceeds 18%. All of these findings have clinical implications. Although treatment effects must be assessed in the context of naturalistic improvement, therapy can hasten remission.     

Long-term course and outcome in unipolar affective and schizoaffective psychoses

ABSTRACT– Of 301 first-time admitted patients with delusional psychoses, 50 met DSM-III criteria for major depressive disorder (MDD), 33 schizoaffective disorder, depressive type (SADD), and 94 schizophrenia. At personal follow-up after 3–39 (mean 22) years, the SADD group was recorded in between on course and outcome variables, but closer to MDD. The findings in MDD and SADD were respectively: remission 66% vs. 42%, personality disorders 14% vs. 12%, anxiety disorder or alcohol abuse 2% vs. 6%, psychosis 18% vs. 36% (with bipolar development in 2% vs. 6%, paranoid disorder 2% vs. 3%, schizophrenia 4% vs. 3%). Chronic psychosis was recorded in 10% vs. 27%. No significant outcome difference was found between early onset MDD and SADD cases and those who fell ill at a higher age. The assumption that antidepressants may induce mania could not be confirmed. Normal premorbid personality seemed to predict a favourable course.     

Platelet MAO activity and long-term outcome in schizophrenia and schizoaffective disorder

Several years after MAO activity determination, 36 patients with schizophrenia or schizoaffective disorder were contacted for assessment of their outcome. Patients who had had low platelet MAO activity had significantly better social adjustment and fewer schizophrenic symptoms at follow-up.     

Interference control commonalities in patients with schizophrenia,bipolar disorder,and borderline personality disorder

Background: Whereas deficits in executive functioning have been widely reported in schizophrenia and, somewhat less, in bipolar disorder, few studies have addressed this issue in people diagnosed with borderline personality disorder. Importantly, no studies to date have compared the ability to cope with interfering information in all three groups of patients. Impairment in executive control has been associated with reduced daily functioning. Method: The sample included 20 patients diagnosed with schizophrenia, 19 with bipolar disorder, 20 with borderline personality disorder, and 19 demographically matched healthy volunteers. Participants were administered two different experimental tasks to assess the ability to exert control over interference arisen from semantic memory or from distracting perceptual information. Results: The three groups of patients showed similar impairment in solving interference from semantic memory compared to controls. However, no psychiatric group showed impairment in controlling interference from distracting perceptual information relative to controls. Conclusions: Our study shows, for the first time, that schizophrenia, bipolar disorder, and borderline personality disorder entail a common impairment in exerting control over interference arisen from memory but intact control over perceptual interference. These findings reinforce the idea that similar cognitive functioning may underlie severe mental disorders sharing poor global functioning but with different patterns of symptomatology.     

Predicting outcome for borderline personality disorder

The purpose of this study is to identify variables predictive of the psychosocial outcomes of borderline patients 2 years following an acute psychiatric hospitalization. Of the initial 88 inpatients scoring positive for the Diagnostic Interview for Borderlines (DIB), 65 (73.8%) were reinterviewed, 14 (15.9%) refused, five (5.7%) were unable to be located, and four (4.6%) suicided. The dropouts (n = 19) were significantly more likely to be single, separated, or divorced, to be male, and to be diagnosed as having co-existing antisocial personality disorder than the followed-up probands (n = 69). In terms of global functioning, over the 2-year follow-up period, 61 (87.7%) of the 69 probands were judged to be functioning normally less than 50% of the follow-up interval. Using logistic regression, two variables, initial impulse action scores and poor premorbid functioning, predicted poor versus good outcome. This study supports the literature, which indicates that the early course of borderline personality disorder (BPD) is stormy. Impulsivity and poor premorbid functioning may be predictive of poor short-term outcome in borderline patients.     

Predictors of 2-year outcome for patients with borderline personality disorder

OBJECTIVE: The primary purpose of this report was to investigate whether characteristics of subjects with borderline personality disorder observed at baseline can predict variations in outcome at the 2-year follow-up. METHOD: Hypothesized predictor variables were selected from prior studies. The patients (N=160) were recruited from the four clinical sites of the Collaborative Longitudinal Personality Disorders Study. Patients were assessed at baseline and at 6, 12, and 24 months with the Structured Clinical Interview for DSM-IV Axis I Disorders; the Diagnostic Interview for DSM-IV Personality Disorders, a modified version of that instrument; the Longitudinal Interval Follow-Up Evaluation; and the Childhood Experiences Questionnaire-Revised. Univariate Pearson's correlation coefficients were calculated on the primary predictor variables, and with two forward stepwise regression models, outcome was assessed with global functioning and number of borderline personality disorder criteria. RESULTS: The authors' most significant results confirm prior findings that more severe baseline psychopathology (i.e., higher levels of borderline personality disorder criteria and functional disability) and a history of childhood trauma predict a poor outcome. A new finding suggests that the quality of current relationships of patients with borderline personality disorder have prognostic significance. CONCLUSIONS: Clinicians can estimate 2-year prognosis for patients with borderline personality disorder by evaluating level of severity of psychopathology, childhood trauma, and current relationships.     

The interface between borderline personality disorder and affective disorder

The authors review the available literature on the interface between borderline personality disorder and affective disorder. Three competing hypotheses have been offered to explain the substantial overlap between these diagnostic categories; they postulate that borderline disorder arises from affective disorder, that affective disorder arises from borderline disorder, or that the two are independent and overlap coincidentally. None of these hypotheses satisfactorily explains the existing data. The authors propose a fourth hypothesis focusing on the multiple etiologies of the signs and symptoms used to diagnose both affective and borderline disorders and suggesting that some patients in the resulting heterogeneous population have symptom clusters that fit both syndromes.     

An outcome study of psychotherapy for patients with borderline personality disorder.

OBJECTIVE: This study evaluated the effectiveness of well-defined outpatient psychotherapy for patients with borderline personality disorder. METHOD: Thirty patients with borderline personality disorder diagnosed according to the DSM-III criteria were given twice weekly outpatient psychotherapy for 12 months by trainee therapists who were closely supervised. The treatment approach was based on a psychology of self (this term being used in its broad sense), and strong efforts were made to ensure that all therapists adhered to the treatment model. Outcome measures included frequency of use of drugs (both prescribed and illegal), number of visits to medical professionals, number of episodes of violence and self-harm, time away from work, number of hospital admissions, time spent as an inpatient, score on a self-report index of symptoms, and number of DSM-III criteria (weighted for frequency, severity, and duration) fulfilled. RESULTS: The subjects showed statistically significant improvement from the initial assessment to the end of the year of follow-up on every measure. Moreover, 30% of the subjects no longer fulfilled the DSM-III criteria for borderline personality disorder. This improvement had persisted 1 year after the cessation of therapy. CONCLUSIONS: The results suggest that a specific form of psychotherapy is of benefit for patients with borderline personality disorder.     

Psychopathological and social status of patients with affective, schizophrenic and schizoaffective disorders after long-term course

A total of 106 affective, 101 schizoaffective and 148 schizophrenic disorders were investigated after a long-term course of illness (mean follow-up period 25.1 years), employing narrow definitions and using reliable international instruments of evaluation. In addition, the social consequences of the illness were evaluated (upward and downward social and occupational drift, premature retirement and achievement of the expected social development). Considering all aspects of outcome, schizophrenic patients (narrow defined, slightly modified DSM-III criteria) had persistent alterations in several aspects of social life, communication and cognitive functions, in some cases to a very high degree. Although the outcome of affective disorders is not always favourable, it is significantly more favourable than that of schizophrenia. Schizoaffective disorders occupy a position between affective and schizophrenic disorders regarding outcome, but with more similarities to that of affective than to that of schizophrenic disorders.     

Discriminating characteristics of suicides. Chestnut Lodge follow-up sample including patients with affective disorder, schizophrenia and schizoaffective disorder

Diagnostic, demographic, and outcome profiles were compared between psychiatric inpatients and former inpatients who ultimately committed suicide and those who did not. Results showed that the suicide group contained a greater preponderance of males and patients suffering from schizoaffective disorder or unipolar depression, and comparatively fewer patients with borderline personality disorder. The suicide group also had histories or symptoms indicative of affective difficulties, and premorbidly had achieved a higher IQ and higher levels of socioeconomic functioning. They also demonstrated higher levels of psychopathology on admission and their post-hospitalization courses were characterized by lower levels of functioning. The risk of suicide thus appeared to be correlated to illness virulence and to the magnitude of the loss of healthy functioning.     

Examining the course and outcome of individuals diagnosed with schizophrenia and comorbid borderline personality disorder

This research examined the prevalence of comorbid borderline personality disorder (BPD) in a sample of schizophrenia inpatients, and then investigated the degree to which BPD comorbidity impacted symptom and functional outcomes after 1-year post-hospital discharge. A sample of 142 individuals with a diagnosis of schizophrenia (n = 100) or schizoaffective disorder (n = 42) from the MacArthur Violence Risk Assessment Study were administered the Structured Interview for DSM-III-R Personality (SIDP-R). Symptom and functional outcome data were gathered during hospitalization and at 1-year follow-up to analyze differences in symptom and functioning characteristics between those diagnosed with and without BPD. Results indicated that comorbid BPD was present in a non-trivial proportion (17.6%, n = 25) of the sample, based on SIDP-R assessment. Baseline analyses indicated that patients with BPD presented with modest elevations in the severity of overall psychiatric symptomatology, and higher levels of anxiety and depression, at hospitalization compared to non-BPD patients. At 1-year follow-up, results revealed that after adjusting for baseline differences, patients with schizophrenia and comorbid BPD showed significantly less improvement in psychiatric symptomatology, particularly hostility and suspiciousness, as well as global functioning, and were re-hospitalized at significantly higher rates than patients without BPD. Our findings indicate that the co-occurrence of schizophrenia and BPD is not infrequent and that BPD has a significant negative longitudinal impact on the course and outcome of patients with schizophrenia.     

Elements of affective instability associated with suicidal behaviour in patients with borderline personality disorder

OBJECTIVE: To identify elements of affective instability associated with an increased likelihood of impulsivity and then to determine whether these elements characterize patients with borderline personality disorder (BPD) and suicidal behaviour. METHOD: We prospectively followed 82 individuals with BPD and a history of recurrent suicidal behaviour who recorded their current mood states, impulsivity, suicide ideation, and environmental stressors (triggers) 6 times daily over 3 weeks. RESULTS: Our results suggested that mood amplitude was correlated with impulsivity and that 4 subgroups defined by mean scores on mood amplitude and negative mood intensity significantly differed in the number of suicidal behaviours reported in the last year. CONCLUSIONS: A subgroup of BPD patients appears to be at elevated risk for suicidal behaviour based on high mood amplitude and mean negative mood intensity. Clinicians might target this group for monitoring and interventions to reduce the likelihood of suicidal behaviour.     

Borderline personality disorder and unipolar affective disorder. Long-term effects of comorbidity

This study tracks the baseline clinical presentation and long-term course (average 15 years) of three patient groups defined largely by DSM-III from the Chestnut Lodge follow-up study: unipolar affective disorder (UNI, N = 22), borderline personality disorder (BPD, N = 55), and a comorbid cohort (UNI/BPD, N = 21). Comorbid BPD effects on UNI include earlier onset and absence of psychotic symptoms at baseline and more substance abuse and use of psychiatric treatment at follow-up. Comorbid UNI effects on BPD include better premorbid instrumental functioning, later onset at baseline, and a higher risk for suicide over the long term. Other noteworthy findings are a low rate of suicide (2%) among the noncomorbid BPD patients and a high rate of diagnostic instability (68%) among the noncomorbid UNI patients. Findings demonstrate a lack of syndromal stability within and among all three study groups and highlight the shortcomings of DSM-III for the investigation of comorbidity.     

A family study of psychotic symptomatology in schizophrenia,schizoaffective disorder,unipolar depression,and bipolar disorder

Summary An evaluation was made of schizophrenics (140), schizoaffectives (40), unipolar depressives (59), and bipolars (30), and their relatives who had a chart diagnosis of psychosis or depressive neurosis. The purpose was to determine whether the psychosis (delusions and hallucinations) was transmitted independently of the illness itself. If this were true, there would be an excess of pairs of probands and relatives both positive for psychosis and pairs of relatives and probands both negative for psychosis when compared to relatives and probands who were not concordant for the variable. This was found to be true in schizophrenia and schizoaffective disorder and is probably the result of the simple transmission of an illness which includes the presence of psychotic symptoms in the definition. Thus, this would be a manifestation of the genetic propensity in schizophrenia. For the affective disorders there was no evidence that psychotic probands were more likely than the nonpsychotic to have psychotic relatives. So far the reason why some patients have psychosis and others not in the affective disorders remains unexplained.
