The Amsterdam post-booking diversion program; a new program for mentally disordered suspects
Interrater Reliability of the Psychological Mindedness Assessment Procedure, Extended (Dutch) Version, in a Clinical Patient Population
The Psychological Mindedness Assessment Procedure, Extended Dutch Version (PMAP-plus), was developed to assess psychological mindedness in mental health care. Psychological Mindedness represents the ability to understand self and others through mental representations of internal psychodynamic states. In patients, deficits in psychological mindedness capacity can cause problems in self- and interpersonal functioning. This brief report describes in…

Treatment of patients with anorexia nervosa and comorbid post-traumatic stress disorder; where do we stand? A systematic scoping review
The findings of this review identify a dearth of treatment research on knowledge of concurrent trauma-focused treatments for patients with anorexia nervosa. Refraining patients with anorexia nervosa from trauma-focused treatment may not be warranted
Norms and T-scores for screeners of alcohol use, depression and anxiety in the population of Suriname
The appropriateness of these cut-offs and the value of converting raw scores into T-scores are discussed. Cut-off values help with screening and early detection of those who are likely to have a common mental health disorder and may require treatment. Conversion of raw scores to a common metric in this study facilitates the interpretation of questionnaire results for clinicians and can improve health care provision through measurement-based care
The effectiveness of an additive informal social network intervention for forensic psychiatric outpatients
This is the first RCT examining the effectiveness of an additive informal social network intervention in forensic psychiatric outpatients. Although no improvements were found on mental wellbeing, the additive intervention was effective in reducing hospitalization and criminal behavior. The findings suggest that forensic outpatient treatment can be optimized by collaborating with informal care initiatives aimed at improving social networks within …
A survey of depression and anxiety disorders in urban and rural Suriname
A high depression rate has been found in both areas, especially among young females. In addition, a high treatment gap is noted which insinuates that more therapeutic strategies are required to tackle depression and anxiety in Suriname
Police Encounters, Agitation, Diagnosis, and Employment Predict Psychiatric Hospitalisation of Intensive Home Treatment Patients During a Psychiatric Crisis
Objective: This study aims to determine factors associated with psychiatric hospitalisation of patients treated for an acute psychiatric crisis who had access to intensive home treatment (IHT). Methods: This study was performed using data from a randomised controlled trial. Interviews, digital health records and eight internationally validated questionnaires were used to collect data from patients on the verge of an acute psychiatric crisis enrol…
The Temporal Associations of Therapeutic Alliance and Manual Adherence With Depressive Symptom Change in Cognitive Behavioral Therapy for Adult Outpatient Major Depression
Background: The therapeutic alliance is considered an important causal agent of psychotherapy efficacy. However, studies in cognitive behavioral therapy (CBT) for depression have suggested that alliance might be more of a consequence rather than a cause of depressive symptom change, while adherence to CBT specific techniques was found to be associated with subsequent depression change. We aimed to add to this body of literature by assessing the t…
Clinical Efficacy and Cost-Effectiveness of Imagery Rescripting Only Compared to Imagery Rescripting and Schema Therapy in Adult Patients With PTSD and Comorbid Cluster C Personality Disorder
Background: Posttraumatic stress disorder (PTSD) is a serious and relatively common mental disorder causing a high burden of suffering. Whereas evidence-based treatments are available, dropout and non-response rates remain high. PTSD and Cluster C personality disorders (avoidant, dependent or obsessive-compulsive personality disorder; CPD) are highly comorbid and there is evidence for suboptimal treatment effects in this subgroup of patients. An …
Dying Too Soon
Aims: We aimed to identify baseline predictors of mortality in patients with a severe mental illness (SMI) over a 6-year period and to describe mortality rates as standardised mortality ratios (SMRs). We hypothesised that cardiovascular diseases, older age, cigarette smoking, more severe psychiatric symptoms and more severe psychotropic side effects, and alcohol or drug use were independent risk factors for mortality. Method: Medical examinations…
The impact of affective symptoms on personal recovery of patients with severe mental illness
BACKGROUND: Clinical recovery is often defined as remission of symptoms. Personal recovery is described as growing beyond the catastrophic effects of mental illness, sometimes despite ongoing symptoms. AIMS: To examine the relationship between the severity of clinical symptom domains and personal recovery in patients with severe mental illness (SMI). METHODS: Symptom severity and personal recovery of 105 outpatients with SMI at Mentrum, part of A…
Comparative Effect of Collaborative Care, Pain Medication, and Duloxetine in the Treatment of Major Depressive Disorder and Comorbid (Sub)Chronic Pain
In MDD and pain, patient's compliance and placebo effects are more important in attaining effect than choice of one of the treatments. Active pain management with COX inhibitors and pregabalin as alternatives to tramadol or other opiates might provide an attractive alternative to the current WHO pain ladder as it avoids opiate prescription as much as possible. The generalizability is limited due to the small sample size. Larger studies are needed
Social inclusion and relationship satisfaction of patients with a severe mental illness
BACKGROUND: Research suggests that patients with a severe mental illness (SMI) are among the most social excluded in society. However, comparisons of social network composition and relationship satisfaction between SMI patients and a control group are rare. AIMS: Our aim was to compare differences in size, satisfaction and composition of the social network between patients with SMI and a control group. Potential sociodemographic and clinical risk…
Changing patient perspectives after compulsory admission and the risk of re-admission during 5 years of follow-up
OBJECTIVE: Given increasing numbers of compulsory admissions, it is important to assess patient risk profiles and identify factors that are appropriate for intervention. METHODS: A sample of 116 patients who were compulsorily admitted was studied. Socio-demographic and clinical characteristics were recorded. Patients were interviewed twice using the Verona Service Satisfaction Scale and the Birchwood Insight Scale. Changes in insight and satisfac…
Measuring shame regulation
Shame is a powerful self-conscious emotion that can interfere with healthy psychological functioning. We examined the validity of the Compass of Shame Scale (CoSS), a self-report measure designed to assess shame regulation styles. In this paper, the construct validity of the Dutch version and two newly developed subscales of the CoSS were investigated in a survey of 324 adolescents. The results confirmed that the Dutch version and the two new sub…
The influence of acculturation on mental health and specialized mental healthcare for non-western migrants
BACKGROUND: The level of acculturation of migrants varies and is associated with variations in mental health. However, this association is complex and may differ among migrant groups. AIM: The aim of this study is to explore the association between acculturation, mental health and treatment effect. METHODS: In a longitudinal cohort study of patients treated in specialized mental health facilities, different dimensions of acculturation (skills, so…
Patient perspectives and the risk of compulsory admission
OBJECTIVE: Compulsory admission to a psychiatric hospital is associated with a three- to fourfold increase in the risk of another compulsory admission. Given the rising numbers of civil detentions in The Netherlands and other European countries, it is important to understand the mechanism behind this association. Our aim is to study the links between opinions about prior psychiatric treatment, insight, service engagement and the risk of (new) civ…
Are long-term psychiatric patients causing more crisis consultations outside office hours in mental health care
BACKGROUND: As well as an improvement in community services, the de-institutionalization of patients receiving long-term psychiatric care can lead to marginally staffed mental health services, more homelessness, rising admission rates and more people in prison cells. It is assumed that an imbalance between community and hospital care for chronic patients puts pressure on crisis services. AIMS: In this study, the central question is whether patien…
Psychometric Properties of the Dutch Version of the Self-Sufficiency Matrix (SSM-D)
Factors associated with higher risks of emergency compulsory admission for immigrants
OBJECTIVE: Specific ethnic groups appear to be disproportionally represented in emergency compulsory admissions. This may be due to a parallel higher risk of psychopathology, but different pathways to care in patients from ethnic minorities may also be an explanatory factor. In this article we concentrate on the influence of ethnic background, pathways to psychiatric emergency services and the amount of past psychiatric treatment as predictors of…
Comorbidity of anxiety and depressive disorders
Background: Overlap of depressive and anxiety symptoms is supposedly more common in non-Western populations. This can lead to diagnostic uncertainity and undertreatment. Aims: The aim of this study was to assess cross-cultural differences regarding the comorbidity of anxiety and depressive disorders in a comparative population study. Methods: In a random urban population sample, stratified for descent, in Amsterdam, the Netherlands, diagnostic in…
Ethnic differences in the association between cardiovascular risk factors and psychological distress in a population study in the Netherlands
In this cross-sectional multi-ethnic adult population sample the majority of the investigated cardiovascular risk factors were not associated with psychological distress. The association of obesity with psychological distress varies by gender and ethnicity. Our findings indicate that the prevention of obesity and psychological distress calls for an integrated approach in native Dutch women, but not necessarily in Turkish-Dutch and Moroccan-Dutch …
Designs for Studying the Effectiveness of Long-Term Psychoanalytic Treatments
Long-Term Psychoanalytic Treatments (LTPT) include both long-term psychoanalytic psychotherapy (LTPP) and psychoanalysis (PsAn). Current opinion seems to be that there is some evidence for the effectiveness of LTPP, but none for that of PsAn. This may be due in part to researchers not balancing the level of evidence of randomized controlled studies (RCTs), cohort studies, and pre-post studies with patients’ acceptance of these various research de…
Acculturation and Psychological Distress Among Non-Western Muslim Migrants - a Population-Based Survey
Background: Political and social developments point at increasing marginalization of Muslim migrants, but little is known about its consequences for the mental health of this particular group. Aim: To explore the relationship between acculturation and psychological distress among first-generation Muslim migrants from Turkey and Morocco in the Netherlands. Methods: A cross-sectional study. Respondents were interviewed in their preferred language. …

Urbanisation and Psychiatric Admission Rates in the Netherlands
This article discusses the possible links between urbanisation, demographic variables and psychiatric admission rates. Inpatient psychiatric admission rates were determined for the 647 Dutch municipalities. Then urbanisation was deter mined using 'area address density', a unit of measurement developed by the Dutch Central Statistical Office. Five degrees of urbanisation are distinguished. Twenty- nine demographic variables which might have a theo…
Personality Disorders and Social Functioning in Depressed Patients
There is a high level of comorbidity of personality disorders with major depression. Patients who suffer from both depression and an axis II disorder are, in general, more severely ill and ill for longer periods. The presence of personality disorders also has a negative influence on the social functioning of depressed patients, and it has emerged that certain demographic characteristics are present to a significant extent. This article presents t…
Social deprivation and psychiatric service use for different diagnostic groups
Psychiatric disorders and urbanization in Germany
Psychiatric disorders are more prevalent among the inhabitants of more urbanized areas. probably because of environmental stressors
Uptake of health services for common mental disorders by first-generation Turkish and Moroccan migrants in the Netherlands
About half of the ethnic Dutch, Turkish and Moroccan population in Amsterdam with CMD contact mental health services. Since the primary purpose of specialised mental health services is to treat "cases", this study provides strong indications for equal access to specialised care for these ethnic groups. The purpose of primary care services is however to treat psychological distress, so that access appears to be lower among Moroccan migrants
The Amsterdam Studies of Acute Psychiatry - II (Asap-II)
The current study may provide a deeper understanding of the differences between psychiatric intensive care units that can be used to promote best practice and benchmarking procedures, and thus improve the standard of care
The current status of urban‐rural differences in psychiatric disorders
Peen J, Schoevers RA, Beekman AT, Dekker J. The current status of urban–rural differences in psychiatric disorders. Objective: Reviews of urban–rural differences in psychiatric disorders conclude that urban rates may be marginally higher and, specifically, somewhat higher for depression. However, pooled results are not available. Method: A meta‐analysis of urban–rural differences in prevalence was conducted on data taken from 20 population survey…
Crisis Intervention and Acute Psychiatry in Amsterdam, 20 Years of Change
Aim: There has been a striking increase in the number of compulsory admission proceedings in the Netherlands since 1992, to such an extent that treatment in Amsterdam’s psychiatric clinics is in danger of being dominated by coercive treatment. Our aim was to establish a picture of the changes in emergency psychiatry that have contributed to the increase in the number of acute compulsory admissions. Methods: A cohort ( N = 460) of psychiatric emer…
Victimization of patients with severe psychiatric disorders
The consequences of (re)victimization have barely been subjected to analysis, partially due to the lack of a comprehensive, conceptual model for victimization. This research project will contribute significantly to the scientific development of the conceptual model of victimization in chronic psychiatric patients
