Existing literature indicates that parent and child PTSD are associated with each other. The present study aimed to examine the relation between PTSD-symptoms from parents and PTSD-symptoms from their children and whether boys or girls would experience more PTSD-symptoms with a sample of Dutch families (N = 1017). Additionally, it was examined whether quality of life (QoL) would influence this relationship. Mothers, fathers and children completed a questionnaire on trauma symptoms. The same children did also complete a questionnaire on QoL. The PTSD-symptoms from parents and their children were significant related. Furthermore, was there no significant difference between boys or girls in experiencing PTSD-symptoms. The addition of QoL to the relation between PTSD-symptoms from parents and children did not generate a significant result either, the relation became not stronger or weaker. It is possible that there were no significant results due the fact that PTSD is a complex disorder. The relation between PTSD-symptoms from parents and their children is influenced by multiple factors and this may have an impact on the results. It would be beneficial if future research would examine these factors.Show less

Aan de hand van Sextus Empiricus worden we meegenomen in de zoektocht naar ataraxia. Ataraxia oftewel gemoedsrust, is een staat waarin men vrij is van zorgen en angsten. Volgens Sextus is het bereiken van gemoedsrust niet alleen een therapeutische vaardigheid, maar ook een manier van leven. Deze Pyrronistische manier van leven houdt in dat overtuigingen ten aanzien van non-evidente zaken worden opgeschort om zo gemoedsrust te bereiken. In dit onderzoek is onderzocht of de filosofie van het Pyrronisme ons kan helpen in ons dagelijks leven met onze angsten en stress. Om Pyrronisme te meten is er een vragenlijst opgesteld met non-evidente stellingen (NE-Q). Voor het meten van angst is de GAD-7 gebruikt en voor het meten van stress is de PSS gebruikt. De eerste hypothese was dat sterkere overtuigingen een negatieve relatie hebben met gemoedsrust. De tweede hypothese was dat de relatie tussen sterkere overtuigingen en gemoedsrust verzwakt wanneer men aan mindfulness doet. De hoofdrelatie was niet significant met zowel de GAD-7 als de PSS als afhankelijke variabele. Ook was de moderatieanalyse in beider gevallen niet significant. Wel bleek bij verdere visuele inspectie dat het doen van mindfulness leidde tot meer angst en stress, in tegenstelling tot wanneer men niet aan mindfulness deed. Dit onderzoek wijst uit dat de filosofische stroming van het Pyrronisme als psychotherapie niet toepasbaar is voor de behandeling van angsten en stress in de hedendaagse tijd. Ook kan geconcludeerd worden dat mindfulness de relatie tussen het hebben van sterkere overtuigingen en gemoedsrust niet beïnvloedt.Show less

All eighteen participants received three texts that fit their personal interests (high interest condition) and three texts that did not (low interest condition). After the participants read the texts, their reading comprehension was measured using two types of text questions. In addition, a measure of overall reading motivation was obtained. By differentiating between literal and bridging questions, the current study aimed to get insights into the underlying cognitive processes of reading comprehension. Repeated Measures ANOVA’ s did not show a significant effect of personal interest on reading comprehension, nor when using literal or bridging questions as outcome variables. There was neither an interaction-effect of overall reading motivation. The lack of significant results could be explained by a ceiling effect. An exploratory analysis showed significant chi-square relationship between personal interest and prior knowledge. Overall, we concluded that the study should be repeated with younger participants before final conclusions can be drawn. To get deeper understanding of the underlying cognitive processes, future research should also incorporate on-line measurements of reading comprehension. Abstract (Nederlands) Het voornaamste doel van de huidige studie was om de invloed van persoonlijke interesse op tekstbegrip te onderzoeken. Alle achttien participanten kregen drie teksten toegewezen over onderwerpen die bij hun persoonlijke voorkeur pasten (hoge interesse conditie) en drie onderwerpen die dat niet deden (lage interesse conditie). Na het lezen werd tekstbegrip met twee type tekstvragen gemeten en aanvullend werd een meting gedaan van de algemene leesmotivatie. Door onderscheid te maken tussen letterlijke en overbruggende tekstvragen werd voorzichtig beoogd inzicht te verkrijgen in onderliggende begripsprocessen. Repeated measures ANOVA ’s liet en geen significant effect zien van persoonlijke interesse op het tekstbegrip, ook niet met letterlijke- of overbruggende vragen als uitkomstvariabelen. Er was ook geen interactie-effect met algemene leesmotivatie. Het uitblijven van een effect zou verklaard kunnen worden door een plafondeffect. Met een exploratieve chi-kwadraattoets werd wel een significant resultaat gevonden wat suggereerde dat de mate van voorkennis samenhangt met persoonlijke interesse. Geconcludeerd werd dat de huidige studie zou moeten worden herhaald met jongere participanten voordat sluitende conclusies kunnen worden getrokken. Om dieper inzicht te verkrijgen in onderliggende begripsprocessen, zijn vervolgstudies nodig waarbij ook daadwerkelijk een meting tijdens het lezen wordt gedaan.Show less

Women who have suffered domestic violence have a high chance of developing trauma-related symptoms, which can affect their mental health and parenting skills. Often, these women’s children are at risk of developing externalizing behaviour, which can lead to violent and criminal behaviour in the future. This research aimed to study the relationship between trauma-related symptoms in mothers and externalizing behaviour of their children. The age at which mothers had their first child was used as a moderator. Data was collected within the research project Samen Stap Voor Stap Vooruit, by visiting women in their shelter. There were three visits per participant, each consisting of a set of questionnaires being taken and video recordings being made of the interaction between mother and child. Data from questionnaires of the first visit were used for this paper. After performing regression analyses with trauma-related symptoms and age of first becoming a mother as independent variables and children’s externalizing behaviour as dependent variable, no relation was found between these variables for the total model. However, there was a positive relation between the age at which a mother had her first child and the externalizing behaviour of the participating child. Children of mothers who were older at first conception were more likely to score higher on externalizing behaviour. The idea of social timing can possibly explain this, with older mothers perhaps having a smaller social safety net, more health issues, less energy, or having stayed longer in the abusive relationship. Further research about the possible relation between being a relatively older mother and externalizing problems in the children is encouraged, as current literature about this topic is slim.Show less

The aim of this research was to contribute to the necessary knowledge for preventive action in reducing the development of aggressive behavior. Currently, many trainings and interventions focus on dealing with aggressive behavior reactively. The literature discusses the origin of aggressive behavior and how it can be influenced by both biological and environmental factors. Increased insight into these factors might also allow for more preventive action. However, little is known about the risk factors that can influence the development of aggressive behavior, even though this knowledge is crucial for recognizing these signs and taking. Design. The data for this quantitative study comes from the Mother-Infant Neurodevelopment Study (MINDS). For the current study, 253 mother-child pairs participated. The participants completed several questionnaires for this study: the Cardiff Infant Contentiousness Scale (CICS), the Self-efficacy in the Nurturing Role Scale (SENR), and the Physical Aggression Scale for Early Childhood (PASEC). The questionnaires were about the precursors of aggressive behavior in the child, the mother's sense of parental competence, and the expression of aggressive behavior. Findings. To examine these factors, a multiple regression with interaction effects was conducted. Both the interaction effect and the individual factors were analyzed. It was found that there is no significant interaction effect. However, both the early signs of aggression and the sense of parental competence proved to be significant predictors separately for the development of aggressive behavior in the child. This suggests that if a child exhibits more early signs of aggressive behavior at a younger age (6 months old), the child is more likely to develop aggressive behavior at a later age (12 months). Additionally, this means that if a mother experiences a lower sense of parental competence when the child is younger (6 months old), it can also be a predictor for the development of aggressive behavior in the child. Conclusion. This study confirms that there are already risk factors visible at a young age that increase the likelihood of developing aggressive behavior. For this reason, it is essential to conduct more research on additional possible risk factors and how professionals in practice can identify these factors. Subsequently, interventions for these risk factors can also be explored to take preventive action in combating the development of aggressive behaviorShow less

Maternal depression is one of the most common mental disorders in The Netherlands. In earlier research, an association was found between maternal depression and disturbed development of empathy in their children. The main goal of this thesis is to examine the relation between maternal depressive symptoms and emotion regulation in mothers and infant empathy precursors. Methods. The current study is part of the longitudinal study 'Een Goed Begin’ by Leiden University. The sample consisted of 151 mother-child dyads, the mothers age varied between 17 and 27 years (M = 22.66 years, SD = 2.209). At 20 months post-partum, depressive symptoms were measured with the Beck Depression Inventory (Beck et al., 1996). Emotion regulation was measured with the Difficulties in Emotion Regulation Scale (Gratz & Roemer, 2004). (Precursors of) empathy in children was measured by the Pain Task (Young et al., 1999; Zahn-Waxler et al., 1992) at 30 months. Results. A significant, positive correlation between emotion regulation and depressive symptoms was found, as expected. There is no main effect of maternal depressive symptoms on precursors of empathy, as well as no main effect of maternal emotion regulation on empathy and no interaction effect between the three variables. Conclusion. The results of this study suggest a significant and positive correlation between depression and empathy, where more symptoms of depression correlated with more empathy, contrary to what was expected. In addition, a trend is found between depression and empathy. Therefore, more research regarding this topic is recommended. Improving the understanding of this relationship can lead to the development of a risk profile when mothers suffer from depressive symptoms and targeted interventions for empathy development.Show less

Until today, little research has been done on the negative physical effects that the use of VR can cause in children aged 8-12 years. The aim of the research reported in this paper is to determine whether the use of VR causes negative physical symptoms in children and to what extent gender, level of fun of the VR task and degree of media use are influencing factors regarding such symptoms. In this study, 64 children aged 8-12 years participated. Before and after playing a short VR game, the children completed a questionnaire (CSSQ) measuring cybersickness symptoms. The results showed that children suffered some degree of cybersickness symptoms after playing a short VR game. Nevertheless, the number of children in the study suffering from cybersickness was very small. The factors of gender, degree of media use and level of fun of the VR game did not seem to influence the development of cybersickness symptoms. In follow-up studies, larger subgroups could be examined to determine more accurately at what age cybersickness symptoms are most prevalent.Show less

Shyness is a personality trait known to influence the memory and testimony of adult witnesses. However, the influence of shyness on testimonies has not yet been thoroughly investigated in the case of underage witnesses. The aim of this study was to investigate to what extent shyness of children is related to level of detail and accuracy of their statement during interrogation and whether these variables differed based on the type of recall during the interrogation. The sample consisted of eight to eleven year old children (mean age = 9.91 years, SD = 1.221). First, the children participated in a standardized online yoga lesson. A week later, the children participated in an online interview to talk about the yoga lesson. These interviews were transcribed and coded for level of detail and accuracy. The Emotionality, Activity, and Sociability Temperament Survey for Children (EAS), filled out by one of the parents, was used to measure the children’s shyness. Both Pearson correlations and repeated measures ANOVAs showed no significant relations between shyness and the level of detail and accuracy of children’s statements during an interrogation. No differences on the relations between shyness and the level of detail and accuracy were found between free recall versus cued recall. This suggests that shyness might not be the best predictor of the level of detail and accuracy of children’s statements and that shy children may be equally good witnesses as non-shy children. However, the sample in this study was too small (n = 11) to draw a firm conclusion and a replication study with a larger sample is necessary.Show less

Previous research has shown that child maltreatment not only can affect direct victims but also the children of parents who have experienced maltreatment. This study examines the relationship between mother’s experienced child maltreatment and their children’s behavioral problems, and investigates whether this relationship is moderated by maternal psychopathology. Based on previous research, it was hypothesized that a positive relationship would exist and that this relationship would be stronger for mothers with more psychopathology. The study focuses on mothers and their children residing in Dutch women’s shelters following domestic violence by the mother’s (ex-)partner. A sample of 29 mother-child dyads was recruited with the average age of mothers being 31.6 years (SD = 6.2 years) and of children being 3.2 years (SD = 1.5 years). The Childhood Trauma Questionnaire-Short Form (CTQ-SF) was used to measure mother’s experiences of child maltreatment in their childhood, with the Child Behavior Checklist (CBCL) children’s behavioral problems were evaluated and the Brief Symptom Inventory-18 (BSI-18) was used to assess maternal psychopathology. The results indicated no significant main effect of mother’s experienced child maltreatment on children’s behavioral problems, and no significant moderation effect of maternal psychopathology on this relationship. However, significant main effects were found for mother’s experienced child maltreatment on maternal psychopathology and for maternal psychopathology on children’s behavioral problems, suggesting a potential mediation effect. Possible explanations for not finding the expected main effect and moderation are a low statistical power due to the small sample size and resilience. Therefore, replication studies are warranted. This study enhances the understanding of the complex interplay between child maltreatment, maternal psychopathology, and children’s behavioral outcomes, emphasizing the need for systemic interventions.Show less

Groepen mensen die massaal bijeen kwamen om zich te verzetten tegen het structureel racisme dat afro-Amerikanen dagelijks meemaken. Verder zijn er internationaal ook veel demonstraties om het milieu te verbeteren, zoals schilderijen die worden besmeurd door klimaatactivisten. Deze protesten waren te zien op verschillende media’s en hebben een grote indruk achtergelaten. Racisme en milieuvervuiling zijn beide prominente problemen in de maatschappij en deze kunnen elkaar versterken. Dit is terug te zien bij milieuracisme. Bij milieuracisme wordt een bepaalde groep vanwege hun huidskleur meer benadeeld door milieuvervuiling dan witte mensen. Zwarte mensen hebben door structureel racisme al een grotere differentiële kwetsbaarheid. Dit betekent dat zij op de gebieden toegang tot middelen, politiek en bestuur, cultuur en kennis en informatie te kort komen vergeleken met witte mensen in hun omgeving.Show less
