Background and problem of interest
The peripartum period, i.e. the period during pregnancy and in the first half year postpartum, is a critical period for the mother and child. Although the incidence of suicide among women during pregnancy and after giving birth is lower than that of women who have not given birth, suicide still remains one of the most common leading causes of maternal death after delivery. Studies have shown that the risk of maternal suicide is higher when women experience peripartum depression or anxiety. But less is known about the prevalence of suicidal ideations, suicidal plans, and suicide attempts in the clinical population of women with peripartum psychiatric problems. Also, risk factors for suicide or suicide attempts in this specific population are not yet defined. This information is important to guide clinicians in their decision making.

Study goal
In the current study we will examine the prevalence of suicidal ideation and suicidal behavior among women with psychiatric problems during pregnancy and the postpartum period.

Specific research question

• What is the prevalence of suicidal ideation and behavior in the peripartum period for women with perinatal psychiatric problems?
• What are risk factors for suicidal ideation and behavior in the peripartum period for women with perinatal psychiatric problems?
• What is the prognosis of women with suicidal ideation and behavior in the peripartum period?

Study design (methods, materials)
The research project is part of the IMPROP ‘Improving psychiatric health care with the use of patient information collected in medical files’ research project.

This is a retrospective cohort study with data collected through routine clinical care from the medical files of patients that were treated at the out- and inpatient clinics of the department of psychiatrie at the Erasmus MC. The department of psychiatry is a teriary psychiatric center specialized in pregnancy-related psychiatric disorders.
Data will be collected on psychiatric diagnosis and symptoms, duration and type of treatment/care, psychopharmacological medication use, psychiatric and somatic comorbidity, physical health, pregnancy related information (obstetric and neonatal information and complications related to psychopharmacology of psychiatric disorder), information on intoxications and socioeconomic information.

Expected results
The main study endpoints are answers to the research questions described above, described in a master thesis.

Background and problem of interest
Neurologic side effects known as extrapyramidal symptoms are prominent with antipsychotic medications. Principal manifestations include dystonias, akathisia and parkinsonism. These side effects are highly distressing. Prevention would be the best management strategy. However, we currently lack information to adequately predict the occurrence of these side effects.

Study goal
The goal of this research project find patient and pharmacological characteristics related to the occurrence of extrapyramidal symptoms associated with use of antipsychotic medications.

Specific research question

• What is the prevalence of extrapyramidal symptoms?
• What patient characteristics are related with extrapyramidal symptoms?
• What pharmacological (dose, duration of use, type of antipsychotic) characteristics are related with extrapyramidal symptoms?

Contents/objective
Bipolar disorder is a chronic and severe condition characterized by manic/hypomanic, mixed, and depressive episodes. It is not only an illness of younger adults, but also of the elderly. (Oosterfink, Nolen & Kok, 2014) . Because of the severity of the symptoms, treatment is very important. Lithium is a well-known mood stabilizer for maintenance and acute treatment of bipolar disorder. In younger adults the lithium level for maintenance treatment is between 0.6 -0.8 mmol/l. These limits are controversial in the elderly. For example Sajatovic and Blow (2007) state in their influential book: “To reduce potential side effects and toxicities, clinicians should target moderate plasma concentration ranges 0.4-0.8 mmol/l; however higher concentrations may be necessary.” The authors did not mention if these levels are for maintenance or acute treatment. A literature search revealed a lack of studies comparing these lower with more conventional serum levels. Therefore, in this study our aim is to compare the effectivity of lithium in the range < 0.6 mmol/l with ≥ 0.6 mmol/l.

Our hospital has medical records of 400 elderly patients with a bipolar disorder, using lithium in the past 4 years. The student is expected to collect data about lithium efficacy from the EPD (electronic patient record) and specify his/her question based on a literature study. The student is also expected to write a research report and provide a verbal presentation of the findings at the department of Psychiatry. To get a good understanding of the pathology that is found in the clinic, it is possible to participate in an outpatient or inpatient clinic with a focus on bipolar patients.

Contents/objective
The MPU study group is recruiting two master students who are interested in doing their research internship about a feasibility study on a new quality standard on hospital psychiatry.
An estimated 25-40% of the medically ill patients admitted to a hospital have a co-morbid psychiatric disorder. Numerous studies now demonstrate that patients who have both general medical and psychiatric disorders, have greater morbidity associated with their medical illness, increased health care service use, and worse functional outcomes.
In order to improve care for patients with concurrent medical and psychiatric disorders, we are currently developing a quality standard on hospital psychiatry. The quality standard covers both outpatient care, care delivered by psychiatric consultation-liaison services and care in Medical Psychiatric Units.

From April – June 2016 we will test the feasibility of the new quality standard including the indicators in four hospitals: OLVG and VUMC (both in Amsterdam), Rijnstate (Arnhem) and the Erasmus MC. Your master research preferably starts with preparation and planning in January 2016, from April –June data will be collected at the four locations and in July-August you will analyze the data and write your thesis.
Your research can answer questions on acceptability, implementation or effects of the quality standard and the indicators. We will discuss the specific appropriate research question with each student.
You will get insight in hospital psychiatry in different teaching hospitals and will work together with a variety of care professionals. If you are an enthusiast future colleague interested in clinical research and healthcare organization, please sent your motivation letter and CV to mpu.studygroup@erasmusmc.nl.
Requirements: master student in medicine, health sciences, health policy or healthcare management, fluent Dutch speaking and weekdays OV card.

Background and problem of interest
Although we do not know the exact functions of sleep, sleep plays an important role in restorative processes for the brain. Sleep helps important cognitive functions for every-day functioning, such as attention, memory, and emotion (1). Because of the numerous ways sleep impacts our brain, sleep problems and mental health problems often go hand in hand. The direction of this association is still to be demonstrated. Is it that sleep problems increase the risk of mental health problems, or is it the other way around (2)? Given observations of behavioural problems affecting sleep, and from sleep problems leading to behavioural problems it is most likely that the associations are bidirectional or circular in nature (2). Research is indicating that the amount of sleep has decreased over the last decades, in particular among adolescents (3), what further increases the importance of this research area.

Study goal
The goal of this research project is to further unravel the association between sleep and psychopathology.

Specific research question

• What is the association between sleep and psychotic experiences in adolescents?
• What is the association between sleep and suicidality in adolescents?
• What is the association between sleep and academic achievement?
• What is the relationship between gaming and screentime and sleep?
• How does perceived sleep and chronotype correlates with sleep measured using actigraphy?
• How does the COVID-19 pandemic influence sleep parameters?

Study design (methods, materials)
The research project is part of the iBerry (Investigating Behavioral and Emotional Risk in Rotterdam Youth) Study, a prospective longitudinal cohort study (N=1022). The overall goal of the iBerry Study is to investigate (determinants for) the transition of having non-specific symptoms in adolescence to the development of full-blown psychiatric disorders later in life. Adolescents that participate in the iBerry Study come from the Greater Rotterdam region (the Netherlands), in which both rural and urban places are represented. Every 2-3 years the adolescent and his/her parents are invited to the iBerry research center for follow-up measurements, for a total period of 10 years. The baseline assessment was completed mid-2019, follow-up measurements have started in the beginning of 2019.

The assessments include psychiatric interviews, physical measurements, neuropsychological tests and questionnaires. Amongst these are (either measured from the adolescent, parent or both):

• Sleep and Activity research: actigraphy device (physical activity intensity and sleep/wake measurements), sleep and exercise diary, questionnaires
• Demographic questionnaires
• Psychiatric interview for DSM diagnoses
• Psychiatric symptoms questionnaires: e.g. Youth Self Report (YSR), Child Behavior Checklist (CBCL), Brief Symptom Inventory (BSI)
• Questionnaire about substance use
• IQ: Snijders-Oomen Niet-verbale intelligentietests (SON-R)
• Questionnaires about social media use and gaming (IAT/VAT)

Expected results
We expect to learn more about determinants of sleep problems. Furthermore, we expect sleep problems to be associated with several forms of psychopathology. In addition, poor sleep is likely to be related to decreased academic achievement.

Background and problem of interest
Internet Gaming Disorder (IGD) is tentatively incorporated in the fifth edition of the Diagnostic and Statistical Manual of mental disorders (DSM-5). Proposed as a behavioral addiction, IGD shares many similarities in both physical and psychosocial manifestations with substance use disorder.
Online gaming has greatly increased in popularity in recent years, prevalences of gaming disorders in western countries are estimated at 1-10%. The etiology, the course and the consequences of IGD, however, are not well-understood at this time. IGD does, therefore, appears to be an area in which additional research is clearly needed.

Study goal
The present study aims to map the determinants, course and sequelae of Internet Gaming disorder (IGD) among adolescents.

Specific research question

• What are the important risk factors for the development of IGD?
• What is the natural course of IGD and what are risk factors for persistence of IGD?
• To what extend is IGD comorbid to other mental health disorders, in particular anxiety, depression and attention-deficit hyperactivity disorder?
• What is the association between IGD and academic achievement?

Study design (methods, materials)
The research project is inbedded in the iBerry (Investigating Behavioral and Emotional Risk in Rotterdam Youth) Study, a prospective longitudinal cohort study (N=1022).

Expected results
The current project helps to fill in the gaps of knowledge on Internet Gaming Disorder.
This information is warranted to help create screening and intervention strategies for clinicians, policy makers and educators.

Background and problem of interest
Psychotic-like experiences, such as hallucinations and delusions, are common in children and adolescents. Population-based studies report prevalence rates ranging from 5 to 35%, with a median prevalence of psychotic-like experiences in adolescence of 7,5% (1). Although these experiences are common, psychotic-like experiences at this age are a risk factor for both psychotic and non-psychotic psychiatric disorders, and suicide attempts (2-4). Furthermore, adolescent psychotic-like experiences are associated with adverse social, educational and occupational outcomes in young adulthood (5). Given the unfavorable outcomes associated with psychotic-like experiences in adolescence it is important to recognize those at risk for psychotic-like experiences as early as possible for intervention purposes.

Study goal
The goal of this research project is to better understand psychotic-like experiences in adolescents and how they are associated with emotional and behavioral problems and psychiatric disorders.

Specific research question

• What risk factors are associated with psychotic-like experiences in adolescents? (e.g. major life events, socio demographic characteristics, family characteristics, IQ)
• What is the relationship between psychotic-like experiences and (subclinical) internalizing symptoms or disorders in adolescents? (e.g. depressive symptoms, anxiety)
• What is the relationship between psychotic-like experiences and (subclinical) externalizing symptoms or disorders in adolescents? (e.g. conduct problems, substance use)

Study design (methods, materials)
The research project is part of the iBerry (Investigating Behavioral and Emotional Risk in Rotterdam Youth) Study, a prospective longitudinal cohort study (N=1022) (6). The overall goal of the iBerry Study is to investigate (determinants for) the transition of having non-specific symptoms in adolescence to the development of full-blown psychiatric disorders later in life. Adolescents that participate in the iBerry Study come from the Greater Rotterdam region (the Netherlands), in which both rural and urban places are represented. Every 2-3 years the adolescent and his/her parents are invited to the iBerry research center for follow-up measurements, for a total period of 10 years. The baseline assessment was completed mid-2019, follow-up measurements have started in the beginning of 2019.

The assessments include psychiatric interviews, physical measurements, neuropsychological tests and questionnaires. Amongst these are (either measured from the adolescent, parent or both):

• Demographic questionnaires
• Psychotic-like experiences (PQ-16)
• Psychiatric interview for DSM diagnoses
• Psychiatric symptoms questionnaires: e.g. Youth Self Report (YSR), Child Behavior Checklist (CBCL), Brief Symptom Inventory (BSI)
• Questionnaire about substance use
• IQ: Snijders-Oomen Niet-verbale intelligentietests (SON-R)
• Interview on major life events and traumatic experiences

Expected results
We expect that psychotic-like experiences are associated with more emotional and behavioral problems. The problems occur both before and after the psychotic-like experiences. Furthermore, we expect that adolescents that report psychotic-like experiences more often meet the criteria for psychiatric diagnoses. Psychotic-like experience are proposed as an import risk factor for both psychiatric disorders and adverse outcomes in adolescents.

Background and problem of interest
A recent report from the Netherlands shows that one out of twelve Dutch households has registered problematic financial debts (Centraal Bureau voor de Statistiek, 2020). Having financial debts seems to elevate the risk for several common mental disorders (Meltzer, Bebbington, Brugha, Farrell, & Jenkins, 2013). Besides that, having mental health problems might lead to experiencing financial hardship, suggesting a vicious circle between financial problems and mental health (Kiely, Leach, Olesen, & Butterworth, 2015; Richardson, Elliott, Roberts, & Jansen, 2017). Furthermore, debt attitudes seem to be passed on from parents to children (Almenberg, Lusardi, Säve-Söderbergh, & Vestman, 2018). However, the exact relationship between debts and psychiatric symptoms still remains unclear, as well as factors that might predict the development of financial debts.

Most previous research focused on financial debts and mental health in adulthood. However, especially the transition into adulthood is an interesting period to learn more about the development of both problems and its possible interaction. During this period, adolescents become legally responsible for their own financial matters (Nibud, n.d.). Besides that, this is also a crucial phase for the development of psychiatric disorders (Kessler et al., 2005; Paus, Keshavan, & Giedd, 2008; Schulenberg, Sameroff, & Cicchetti, 2004).

Study goal
The goal of the research project is to examine how financial debts arise in adolescents and to analyze what the effects of poverty and financial debts are on the mental health and vice versa. In this way we hope to find starting points to develop policy and suitable care for adolescents who either develop psychiatric disorders, financial debts, or both.

Specific research question

• What is the relationship between financial debts and (subclinical) internalizing symptoms in adolescents? (e.g. depressive symptoms, anxiety)
• What is the relationship between financial debts and (subclinical) externalizing symptoms in adolescents? (e.g. conduct problems, substance use)
• What are predictors of financial debts in adolescents? (e.g. personality factors, IQ, social support, substance use, financial stress, decision-making abilities, family characteristics, socio demographic characteristics)
• How do financial debts and psychiatric disorders (co-)develop into early adulthood?

Study design (methods, materials)
The research project is part of the iBerry (Investigating Behavioral and Emotional Risk in Rotterdam Youth) Study, a prospective longitudinal cohort study (N=1022) (Grootendorst-van Mil et al, submitted). The overall goal of the iBerry Study is to investigate (determinants for) the transition of having non-specific symptoms in adolescence to the development of full-blown psychiatric disorders later in life. Adolescents that participate in the iBerry Study come from the Greater Rotterdam region (the Netherlands), in which both rural and urban places are represented. Every 2-3 years the adolescent and his/her parents are invited to the iBerry research centre for follow-up measurements, for a total period of 10 years. The baseline assessment was completed mid-2019, follow-up measurements have started since early 2019.

The assessments include psychiatric interviews, physical measurements, neuropsychological tests and questionnaires. Amongst these are (either measured by adolescent, parent or both):

• Demographic questionnaires
• Questionnaires about (family) income and financial debts
• Financial scarcity/stress: Psychological Inventory Financial Scarcity (PIFS)
• Psychiatric interview
• Psychiatric symptoms questionnaires: e.g. Youth Self Report (YSR), Child Behavior Checklist (CBCL), Brief Symptom Inventory (BSI)
• Questionnaire about substance use
• Self-Reported Early Delinquency scale (SRED)
• IQ: Snijders-Oomen Niet-verbale intelligentietests (SON-R)
• Decision making: Iowa gambling task (IGT)
• Social support: Multidimensional Scale of Perceived Social Support (MSPSS)
• Parental involvement: Supervision/Involvement Scale – revised

During the project we collaborate with the Nationaal Instituut voor Budgetvoorlichting (Nibud), an independent organization that investigates, informs and advises about household finances in the Netherlands.

Expected results
It is expected that financial debts have a positive relationship with both internalizing and externalizing symptoms in adolescents, and that this works as a vicious circle over time. Furthermore, it is expected that debts arise from the age of 18 and once they have developed, the total debt amount keeps increasing. Another expectation is that adolescents who develop debts, have parents who have financial problems as well. Other expected determinants for developing debts and co-occurring mental disorders are: IQ, living environment, educational level, social support, risk taking behavior and substance use.

Background and problem of interest
Non-suicidal self-injury refers to the deliberate destruction or alteration of bodily tissue in the absence of suicidal intent, e.g. cutting, burning oneself (1). It typically has its onset and peak in adolescence, with previously found prevalances as high as 20% (2). NSSI has been associated with many other psychiatric problems, like mood, anxiety and substance use disorders and is also one of the strongest predictors for future suicide attempts (3). The World Health Organization states that suicide is the second leading cause of death among persons aged 15-29 years (4). Woman are more likely to self-harm and undertake suicide attempts, but men die more often by suicide than women, probably because of a preference for highly lethal methods (5).
Both NSSI and suicidality are often accompanied by poor social, educational and occupational outcomes and might not resolve without treatment (6). Timely treatment may reduce chances of developing comorbid disorders and enhance treatment outcome. Identifying factors that increase vulnerability is thus essential for prevention and early intervention.

Study goal
The present study wishes to contribute to the understanding of the phenomenology, risk factors and the development of NSSI and suicidality in adolescents by fulfilling important knowledge gaps in the literature.

Specific research question

• What is the association between nonsuicidal self-injury and suicidality in adolescence?
• What risk factors are associated with nonsuicidal self-injury and suicidality in adolescence? (e.g. socio demographic characteristics, IQ, substance use, social support)
• What are the functions of nonsuicidal self-injury in adolescence? (e.g. self-punishment, sensation-seeking)
• What is the association between nonsuicidal self-injury, suicidality and internalizing and externalizing problems?
• What is the association between non suicidal self-injury, suicidality and having psychotic-like experiences?
• What is the association between nonsuicidal self-injury, suicidality and peer victimization?
• What is the association between nonsuicidal self-injury, suicidality and social media use?
• How do nonsuicidal self-harm and suicidality develop into adulthood?

• Suicidality: Vragenlijst Over Zelfdoding en Zelfbeschadiging (VOZZ)
• Demographic questionnaires

• Questionnaire on bullying
• Social support: Multidimensional Scale of Perceived Social Support (MSPSS)
• Interview on major life events and traumatic experiences
• Questionnaire on social media use
• General Assessment of Functioning Scale
• Child Outcome Rating Scale

Expected results
We expect that NSSI and suicidality are strongly associated. We expect that adolescents who report NSSI and/or suicidality report poorer outcomes on general functioning measures and more internalizing, externalizing problems and problematic substance use. Girls will report more NSSI than boys. We hypothesize that motivational background will vary for different types of NSSI and for boys and girls. Girls will more often report suicidal ideation and suicide attempts. Adolescents with a history of significant major life events and traumatic experiences will more often report NSSI or suicidal ideation.

Background and problem of interest
Recovery from psychosis is a construct that has gained increased attention over the past thirty years. Since the early nineties, patients and scientists have underlined the notion that recovery from a psychotic disorder can occur, even with symptoms being present (1-3). Subsequently, there has been increased attention for the multidimensional aspect of recovery in psychotic disorders such as schizophrenia (2). However, there is a large heterogeneity in definitions of recovery shown in the different long-term studies (4). This causes confusion amongst patients, clinicians and researchers, as it remains unclear how different factors may influence different forms of recovery (i.e. personal, functional, social and symptomatic). Therefore, the present study aims at finding determinants of personal recovery, and disentangling time-dependent relationships amongst four dimensions of recovery and its determinants over a ten-year period.

Study goal
This master thesis project will be part of the UP'S (ups and downs) cohort study, were we study recovery over time in people with psychotic disorders. We study the process of recovery, along with various determinants of which we know are of influence on the different forms of recovery and the disorder itself, such as sleep dysfunction, cardiovascular risk and drug-use. However, we do not know the exact effects of these determinants on symptomatology, executive functioning and other forms of recovery over time. It is hypothesized that physical health, drug-use and sleep dysfunction will worsen symptoms and have an incrementing effect on executive functioning over time. As a student, you will be part of this sub-study within the cohort.

Specific research question
Your master thesis’ topic can be about the following subjects:

• Personal recovery
• Executive functioning
• Attachment

If preferable, all subjects can be investigated over time.

Task description
Students will participate in every aspect of the study; informing participants, formulating hypotheses regarding above mentioned topics, collecting and analysing data, and subsequently writing a thesis using the acquired data. We expect students to examine their own research question within the UP’S cohort and present the results at the department of Psychiatry. Data collection consists of extensive interviews which are done every year for ten years. Recruitment of these patients, along with data collection, will be done in corporation of outreaching treatment teams. During the internship, students can therefore be partly working at the site of the teams.
