OBJECTIVE Women with a history of bipolar disorder, postpartum psychosis, or both are at high risk for postpartum relapse. The aim of this meta-analysis was to estimate the risk of postpartum relapse in these three patient groups. METHOD A systematic literature search was conducted in all public medical electronic databases, adhering to the PRISMA guidelines. Studies were included if they reported postpartum relapse in patients diagnosed with bipolar disorder and/or a history of postpartum psychosis or mania according to DSM or ICD criteria or the Research Diagnostic Criteria. RESULTS Thirty-seven articles describing 5,700 deliveries in 4,023 patients were included in the quantitative analyses. The overall postpartum relapse risk was 35% (95% CI=29, 41). Patients with bipolar disorder were significantly less likely to experience severe episodes postpartum (17%, 95% CI=13, 21) than patients with a history of postpartum psychosis (29%, 95% CI=20, 41). Insufficient information was available to determine relapse rates for patients with bipolar disorder and a history of postpartum episodes. In women with bipolar disorder, postpartum relapse rates were significantly higher among those who were medication free during pregnancy (66%, 95% CI=57, 75) than those who used prophylactic medication (23%, 95% CI=14, 37). CONCLUSIONS One-third of women at high risk experience a postpartum relapse. In women with bipolar disorder, continuation of prophylactic medication during pregnancy appears highly protective for maintaining mood stability postpartum. In women with a history of isolated postpartum psychosis, initiation of prophylaxis immediately after delivery offers the opportunity to minimize the risk of relapse while avoiding in utero medication exposure.

Background War has serious and prolonged mental health consequences. It is argued that post-emergency mental health interventions should not only focus on psychological factors but also address the social environment. No controlled trials of such interventions exist. We studied the effect on mental health of a large scale psychosocial intervention primarily aimed at social bonding in post-genocide Rwanda. The programme is implemented at population level without diagnostic criteria for participation. It is open to any person older than 15 years, and enables participation of over 1500 individuals per year. We postulated that the mental health of programme participants would improve significantly relative to non-participants. Methods and Findings We used a prospective quasi-experimental study design with measurement points pre and post intervention and at 8 months follow-up. 100 adults from both sexes in the experimental condition entered the study; follow-up measurements were taken from 81. We selected a control group of 100 respondents with similar age, sex and symptom score distribution from a random community sample in the same region; of these, 73 completed the study. Mental health was assessed by use of the Self Reporting Questionnaire (SRQ-20), a twenty item instrument to detect common mental disorders in primary health care settings. Mean SRQ-20 scores decreased by 2.3 points in the experimental group and 0.8 in the control group (p = 0.033). Women in the experimental group scoring above cut-off at baseline improved with 4.8 points to below cut-off (p<0.001). Men scoring above cut-off at baseline showed a similar trend which was statistically non-significant. No adverse events were observed. Conclusions A large scale psychosocial intervention primarily aimed at social bonding caused a lasting improvement of mental health in survivors of mass violence in Rwanda. This approach may have a similar positive effect in other post-conflict settings. Trial Registration Nederlands Trial Register 1120

BackgroundThis study took place to enable the measurement of the effects on mental health of a psychosocial intervention in Rwanda. It aimed to establish the capacities of the Self-Reporting Questionnaire (SRQ-20) to screen for mental disorder and to assess symptom change over time in a Rwandan community setting.MethodsThe SRQ-20 was translated into Kinyarwanda in a process of forward and back-translation. SRQ-20 data were collected in a Rwandan setting on 418 respondents; a random subsample of 230 respondents was assessed a second time with a three month time interval. Internal reliability was tested using Cronbachs alpha. The optimal cut-off point was determined by calculating Receiver Operating Curves, using semi-structured clinical interviews as standard in a random subsample of 99 respondents. Subsequently, predictive value, likelihood ratio, and interrater agreement were calculated. The factor structure of the SRQ-20 was determined through exploratory factor analysis. Factorial invariance over time was tested in a multigroup confirmatory factor analysis.ResultsThe reliability of the SRQ-20 in women (α = 0.85) and men (α = 0.81) could be considered good. The instrument performed moderately well in detecting common mental disorders, with an area under the curve (AUC) of 0.76 for women and 0.74 for men. Cut-off scores were different for women (10) and men (8). Factor analysis yielded five factors, explaining 38% of the total variance. The factor structure proved to be time invariant.ConclusionsThe SRQ-20 can be used as a screener to detect mental disorder in a Rwandan community setting, but cut-off scores need to be adjusted for women and men separately. The instrument also shows longitudinal factorial invariance, which is an important prerequisite for assessing changes in symptom severity. This is a significant finding as in non-western post-conflict settings the relevance of diagnostic categories is questionable. The use of the SRQ-20 can be considered an alternative option for measuring the effect of a psychosocial intervention on mental health.Trial registrationNederlands Trial Register NTR1120.

Background Although crime victimisation is as prevalent in psychiatric patients as crime perpetration (and possibly more so), few European figures for it are available. We therefore assessed its one-year prevalence and incident rates in Dutch severely mentally ill outpatients, and compared the results with victimisation rates in the general population. Method This multisite epidemiological survey included a random sample of 956 adult severely mentally ill outpatients. Data on victimisation were obtained using the victimisation scale of the Dutch Crime and Victimisation Survey, which assesses crime victimisation over the preceding 12 months. Comparison data were derived from the nationwide survey on safety and victimisation in the Netherlands. Prevalence and incident rates were weighted for sex, age, ethnicity and socioeconomic status, and compared with a general population sample matched by region (N = 38,227). Results In the past year, almost half of the severely mentally ill outpatients (47%) had been victim of a crime. After control for demographic differences, prevalence rates of overall and specific victimisation measures were significantly higher in severely mentally ill outpatients than in the general population. The relative rates were especially high for personal crimes such as violent threats (RR = 2.12, 95% CI: 1.72–2.61), physical assaults (RR = 4.85, 95% CI: 3.69–6.39) and sexual harassment and assaults (RR = 3.94, 95% CI: 3.05–5.09). In concordance, severely mentally ill outpatients reported almost 14 times more personal crime incidents than persons from the general population (IRR = 13.68, 95% CI: 12.85–14.56). Conclusion Crime victimisation is a serious problem in Dutch severely mentally ill outpatients. Mental-healthcare institutions and clinicians should become aware of their patients’ victimisation risk, and should implement structural measures to detect and prevent (re-)victimisation.

IMPORTANCE Compulsory admissions, defined as admissions against the will of the patient (according to local judicial procedures), have a strong effect on psychiatric patients. In several Western countries, the rate of such admissions is tending to rise. Its reduction is urgently needed. OBJECTIVE To establish which interventions effectively reduce compulsory admissions in adult psychiatric patients in outpatient settings. DATA SOURCES A systematic computerized literature search was performed using EMBASE, MEDLINE, Web of Science, PsycINFO, CINAHL, PubMed (not yet indexed for MEDLINE), Cochrane Central, and Google Scholar. Every database was searched from its inception until April 30, 2015. STUDY SELECTION Randomized clinical trials (RCTs) that studied any kind of intervention designed to reduce compulsory admission rates in adult psychiatric patients (age range, 18-65 years) in outpatient settings were eligible. Eligibility was independently assessed by 2 of us. DATA EXTRACTION AND SYNTHESIS Two of us independently extracted relevant data. The Cochrane Collaborations tool was used for assessing risk of bias. Overall risk reduction (random-effects estimate) was calculated in the following 4 subgroups of interventions: advance statements, community treatment orders, compliance enhancement, and integrated treatment. MAIN OUTCOMES AND MEASURES Relative risk (RR) was calculated on the basis of the number of patients who had been compulsorily admitted. RESULTS Our meta-analyses included 13 RCTs comprising 2970 psychiatric patients. The meta-analysis of the RCTs on advance statements showed a significant 23% (RR, 0.77; 95% CI, 0.60-0.98; I2 = 2.2%) (n = 1102) risk reduction in compulsory admissions. In contrast, the RCTs on community treatment orders (RR, 0.95; 95% CI, 0.81-1.10; I2 = 0.0%) (n = 742), compliance enhancement (RR, 0.52; 95% CI, 0.11-2.37; I2 = 55.7%) (n = 250), and integrated treatment (RR, 0.71; 95% CI, 0.49-1.02; I2 = 49.0%) (n = 876) showed no significant risk reduction in compulsory admissions. CONCLUSIONS AND RELEVANCE The meta-analysis of the RCTs on advance statements showed a statistically significant and clinically relevant 23% reduction in compulsory admissions in adult psychiatric patients, whereas the meta-analyses of the RCTs on community treatment orders, compliance enhancement, and integrated treatment showed no evidence of such a reduction. To date, only 13 RCTs have used compulsory admissions as their primary or secondary outcome measure. This demonstrates the need for more research in this field.

Postpartum psychosis is a severe disorder that warrants acute clinical intervention. Little is known, however, about what interventions are most effective. The authors present treatment response and remission outcomes at 9 months postpartum using a four-step algorithm in patients with first-onset psychosis or mania in the postpartum period. Treatment involved the structured sequential administration of benzodiazepines, antipsychotics, lithium, and ECT. The outcome of clinical remission was examined in 64 women consecutively admitted for postpartum psychosis. Remission was defined as the absence of psychotic, manic, and severe depressive symptoms for at least 1 week. Women who remitted on antipsychotic monotherapy were advised to continue this treatment as maintenance therapy, and women who required both antipsychotics and lithium to achieve remission were maintained on lithium monotherapy. Relapse was defined as the occurrence of any mood or psychotic episode fulfilling DSM-IV-TR criteria. Using this treatment algorithm, the authors observed that nearly all patients (98.4%) achieved complete remission within the first three steps. None of the patients required ECT. At 9 months postpartum, sustained remission was observed in 79.7%. Patients treated with lithium had a significantly lower rate of relapse compared with those treated with antipsychotic monotherapy. Multiparity and nonaffective psychosis were identified as risk factors for relapse. The authors conclude that a structured treatment algorithm with the sequential addition of benzodiazepines, antipsychotics, and lithium may result in high rates of remission in patients with first-onset postpartum psychosis and that lithium maintenance may be most beneficial for relapse prevention.

Objective To establish whether patients with a crisis plan had fewer voluntary or involuntary admissions, or fewer outpatient emergency visits, than patients without such a plan. Design Multicenter randomized controlled trial with two intervention conditions and one control condition. Participants Adult outpatients diagnosed with psychotic or bipolar disorder who had experienced at least one psychiatric crisis in the previous two years. Intervention Two types of advance statement were used: (1) a crisis plan formulated by the patient with the help of a patient advocate (Patient Advocate Crisis Plan: PACP); and (2) a crisis plan developed together with the clinician (Clinician-facilitated Crisis Plan: CCP). Outcome The percentages of patients admitted voluntarily or involuntarily (on an emergency basis or by court order), and the percentage who made outpatient emergency visits over an 18-month follow-up period. Results A total of 212 patients were included: 69 in the PACP condition, 70 in the CCP condition, and 73 in the control condition. No effects of the two interventions were found on the numbers of voluntary admissions, involuntary admissions and emergency visits. Regarding involuntary admissions, there was no significant effect on emergency admissions, which were 17% (12/69) in the PACP condition, 10% (7/70) in the CCP condition, and 19% (14/73) in the control condition. There was a significant effect on planned court-ordered admissions, with 16% (11/69) in the PACP condition, 10% (7/70) in the CCP condition, and 26% (19/73) in the control condition. Finally, the interventions had no effect on outpatient emergency visits, with 32% (22/69) in the PACP group, 31% (22/70) in the CCP group, and 34% (25/73) in the control group. Conclusions Crisis plans may be an effective intervention for reducing court-ordered admissions in patients with psychotic and bipolar disorders.

Psychometrics and Validity of the Dutch Experiences in Close Relationships–Revised (ECR–r) in an Outpatient Mental Health Sample

Cornelis G. Kooiman; Ellen R. Klaassens; J. Quintien van Heloma Lugt; Astrid M. Kamperman

The Experiences in Close Relationships–Revised (ECR–r) is a self-report instrument to assess adult attachment style that seems to have appropriate psychometric qualities. The ECR–r has been most widely studied in student and community samples. In this study we report factor structure, reliability, and construct validity of the Dutch translation of the ECR–r in an outpatient mental health sample (N = 262). The original factor structure could satisfactorily be replicated, the reliability of the ECR–r was also stable over time, and there was good evidence for its construct validity.

OBJECTIVE To examine sustainability of symptom outcomes of a 1-year phase-based trauma-focused, multimodal, and multicomponent group therapy in a day treatment program for posttraumatic stress disorder (PTSD) over an average period of 7 years. METHOD Iranian and Afghan patients (N = 69) were assessed with self-rated symptom checklists for PTSD, anxiety, and depression symptoms before (T1), after (T2), and up to 11 years upon completion of the treatment (T3). A series of mixed model regression analyses was applied to determine the course of the measured symptoms over time. RESULTS At T2, all symptoms were reduced, but PTSD symptoms showed the strongest reduction. The trend of symptom reduction continued up to 5 years posttreatment and was similar for all the examined symptoms. After 5 years, all symptoms started to worsen, but remained under baseline levels at T3. CONCLUSIONS The applied treatment appears to improve mental health of the studied sample on both the short and longer term.

Abstract Studies on group treatment of posttraumatic stress disorder (PTSD) in asylum seekers and refugees are scarce. The aim of this study was to evaluate the effectiveness of three different trauma-focused day-treatment group programs for treatment of PTSD in male asylum seekers and refugees. Three treatment groups (n = 56) and a waitlisted control group (n = 16) of help-seeking Iranian and Afghani patients were assessed with a set of self-rated symptom checklists for PTSD, anxiety, depression, and psychoticism 1 week before and 2 weeks after treatment. There are no indications that the 2 days’ group program with three nonverbal and two group psychotherapy sessions per week is less effective in reducing symptoms than the program with the same amount of sessions spread over 3 days per week. The trauma-focused day-treatment group seems a promising approach for treatment of PTSD among asylum seekers and refugees in industrialized settings.
