Data were collected from 65 pre-service teachers who completed measures of connectedness, perspective-taking difficulty, and emotional exhaustion. Correlation analysis revealed weak, non-significant relationships among the variables and regression analyses indicated that connectedness was not a significant predictor of perspective-taking efforts. Additionally, emotional exhaustion did not moderate the relationship between connectedness and perspective-taking. The findings highlight the need for professional development programs aimed at enhancing teacher-student relationships and equipping teachers with strategies to manage emotional exhaustion and strengthen perspective-taking, contributing to a more positive and effective educational environment.Show less

About 1 in 650-1000 children are born with an extra X or Y chromosome. These common chromosomal abnormalities, including XXY/Klinefelter syndrome, XXX/Trisomy X and XYY syndrome, affect both physical development and behaviour. There is an increased risk of behavioural problems, including autism spectrum disorder (ASD) symptoms, in children with SCT (Rijn, 2019; Tartaglia et al., 2010; Urbanus, 2022). Despite these findings, there has been limited research on the variations in ASD characteristics in children with SCT and possible protective and risk factors. Therefore, this study aims to better understand the characteristics of ASD in children with SCT, identify possible protective and risk factors related to parenting skills for this group, and ultimately optimise support measures, early detection and appropriate interventions for this specific genetic population. For this purpose, the following research question was formulated; Is there a difference in the level of ASD characteristics in children with SCT 3-7 years compared to peers? And to what extent do the parenting skills (mentalisation and sensitivity) of parents with children aged 3-7 years with SCT correlate with the level of autism spectrum disorder (ASD) characteristics of this specific population? Data for this study is selected from a larger quantitative study conducted by Leiden University and the TRIXY Centre of Expertise. Children with SCT and their parents were recruited through support groups and clinical genetics departments in hospitals in the Netherlands, Belgium and the US. The control group was recruited from nurseries, public locations and primary schools. The study includes 145 children aged between 3 and 7 years, with 71 participants in control group and 74 participants in the SCT group. This study showed that a significant difference was found in the level of autism traits between children with SCT and children without SCT. Children with SCT scored significantly higher on every autism trait that was tested. In addition, no correlation was found between parenting skills; sensitivity and mentalisation and the level of autism traits in children with SCT. Based on this, a dimensional approach, rather than a binary criterion, is recommended as this could help detect subtle variations and gradations in ASD symptoms earlier, enabling early diagnosis. In addition, this research outcome implies that other factors such as biological, neurological and other environmental factors may have a greater influence on the level of ASD characteristics in children with SCT. More research needs to be done on this to say this with great certainty. This study is limited by no distinguish between different types of sex chromosome trisomy, which may limit the generalisability of the results. In addition, the study included children aged 3-7 years, but at this stage children develop rapidly, and ASD traits may manifest differently depending on age, which may limit the generalisability of the results to any age between 3 and 7 years. Besides these limitations, the study also has many strengths, such as contributing to increasing scientific knowledge about ASD traits in children with SCT, early detection of these and possible risk and protective factors.Show less

Enhancing the self-regulation of energy intake, the ability to respond to one's own hunger or satiety signals, can reduce the risk of obesity (DiSantis et al., 2011). Promoting the self-regulation of energy intake as early as possible in development is therefore crucial. The present study examined the relation between maternal sensitivity in different contexts (during free play and during meals) at 18 months and the child's self-regulation of energy intake at 24 months. The sample consisted of 103 mother-child dyads (41.7% boys), obtained from the longitudinal study "Baby's first bites” (Van der Veek et al., 2019). Maternal sensitivity was measured using “the Ainsworth Maternal Sensitivity Scale” (Ainsworth et al., 1974). The self- regulation of energy intake was assessed using an “Eating in Absence of Hunger” paradigm (Schultink et al., 2021). First, no significant relation was found between maternal sensitivity during free play at 18 months and self-regulation of energy intake at 24 months. Second, maternal sensitivity during mealtime at 18 months was not related to self-regulation of energy intake at 24 months. Finally, maternal sensitivity during free play and during mealtime at 18 months did not make a unique contribution to the child's self-regulation of energy intake at 24 months. This study contributed to the emerging research area of parenting practices and the self-regulation of energy intake. Based on the current research, it cannot be stated that maternal sensitivity contributes to the child's self-regulation of energy intake. Therefore, it is not yet clear how parents can best contribute to good self-regulation of energy intake. Follow-up research is needed.Show less

By taking the student’s perspective, the teacher should be able to understand the student better and react more responsively. Through this the teacher experiences more positive interactions with the student which contribute to developing and maintaining a positive student-teacher relationship. It is suggested that teachers’ sense of self- efficacy could play a role in the relationship between student-perspective taking and the student- teacher relationship. Therefore, the current study researches the relationship that is described above, and the potential role the teacher’s self-efficacy plays within this. The sample consisted of 133 Dutch regular primary school teachers. Results showed a significant relationship between student-perspective taking and the student-teacher relationship when teachers take the student’s perspective on the level of articulation. The relationship with taking the student’s perspective on the level of positioning, is non-significant. Regarding the role of teachers’ self-efficacy within this relationship, the results show that there is no mediating role. Meanwhile, a significant, positive relationship has been found between the teacher’s self-efficacy and the student-teacher relationship. The findings of this study can be used in developing and shaping interventions for teachers for developing, improving and maintaining positive student-teacher relationships.Show less

Additionally, it focused on optimal integration of mental health care into gender-affirming care according to TGD individuals. Both were within the framework of an ongoing investigation at the Zaans Medical Centre. The quantitative data analysis consisted of intake questionnaire data of twenty-five TGD individuals, variables were derived from sections of the intake questionnaire. For the qualitative data analysis, seven semi-structured interviews were held with TGD individuals. The characteristics of TGD individuals consisted of self-reported psychological distress and well-being. Their relationship to requested mental health care intensity was studied through Spearman rank order correlations. The demographics included age, educational level, ethnicity, employment status, experienced income, and gender assigned at birth. Their association with requesting mental health care was explored through chi-square tests. A thematic analysis with semantic approach was performed to analyse the data. No significant correlations were found between demographic variables and mental health care requests at admission. The correlation between self-reported psychological distress and mental health care intensity was χ2 = -.003, p = .987, for self-reported psychological well-being and mental health care intensity χ2 = -.001, p = .997. Thematic analysis of interview data yielded three overarching themes: motives for seeking mental health care, recommendations for integrating mental health services into gender-affirming care, and desirable attributes of mental health care providers. Reasons for refraining from or seeking mental health care included experiencing psychological distress or good psychological well-being, experiences due to gender dysphoria, acceptance of themselves, and experienced lack of support. Suggestions for optimal mental health care integration were better and more provision of (mental) health care and travel distance to mental health care. Qualities of the ideal mental health care professional were having certain character traits such as being accepting and being specialized in TGD. Overall, this research emphasizes the importance of knowledgeability and empathetic and inclusive qualities in mental health care professionals in the treatment of TGD individuals suggesting its importance over mental health care professionals’ gender identity.Show less

Understanding the factors that influence vegetable intake is vital for promoting healthy development in children, as unhealthy eating habits can increase the risk of diseases like cardiovascular conditions, cancer, and diabetes. A cross-sectional study was conducted with a sample of 256 mother-child dyads (age children M = 4,68, SD = 0,42). Participants were recruited through email lists and child health centers in four Dutch provinces, targeting mothers about to introduce solid foods to their 4-6 month-old infants The data in this study was collected from the same sample of children, but when they were 24 months old. Information about the variables was gathered using multiple questionnaires: Compl-Eat, Meals in Our Household, CFPQ, and CEBQ-T. Results show that less picky children consume significantly more vegetables on average than picky children, with an average difference of 38.64 grams. However, no significant effects were found for parental encouragement or the frequency of family meals at the table on vegetable intake. Possible explanations for the lack of significant results include the skewed data distribution and potential social desirability bias in parental reporting. Future research should aim to precisely define and measure 'encouragement' and 'meals at the table', considering factors like frequency, method, and context. This will lead to the development of more precise measurement tools, improving the accuracy and reliability of findings. These insights are crucial for developing effective interventions to promote vegetable consumption in children and improve their overall health.Show less

I focus on marginalised groups whose experiences often diverge from mainstream perspectives. Through case studies such as the Minha Casa Minha Vida project in Brazil and Hyde Park in the United States, this thesis highlights how these communities infuse spaces with personal and collective memories, influencing their interactions with the environment. These studies suggest that standardised urban planning policies may overlook the lived realities of marginalised communities, leading to social sustainability initiatives that fall short of addressing their needs. By examining the complex social, historical, and economic factors that shape human-environment relations, the thesis proposes a reimagined approach to urban planning that could foster more inclusive, equitable and supportive urban spaces.Show less

Therefore, a deeper understanding of the underlying mechanisms may help improve the treatment. Inhibitory learning has been a recently developed approach, stating that new fear associations must be actively developed. One proposed strategy has been that of expectancy violation, in which threat expectancies are actively challenged during exposure. Actively experiencing a mismatch between expectancy and reality is supposed to benefit learning and thus improve exposure success, yet results have been mixed. The aim of this study was to expose the mechanisms of expectancy violation by analyzing the types of expectancies experienced by PTSD patients. Furthermore, the effects of the strength of these expectancies and the extent to which they change in strength during exposure on treatment success was tested. In a clinical assay, participants (N = 60) were randomized across two groups, which both received exposure therapy. The experimental group’s exposure treatment was designed to enhance expectancy violation. In both groups, PTSD symptoms were measured at baseline and follow- up, and threat expectancies were measured right before and right after exposure. Results showed that both threat expectancies and PTSD symptoms reduced significantly. However, baseline expectancy strength did not have a significant effect on the amount of PTSD symptom reduction, both in the total and the experimental group. Furthermore, the amount of expectancy change did not predict PTSD symptom reduction either. A full ranking of expectancy types was provided.Show less

Brooding rumination is a symptom and a risk factor for depression. The default mode network (DMN) is active during brooding rumination. Inadequate suppression of this network obstructs activation of the central executive network (CEN), essential for performing cognitively demanding tasks. While previous research linked DMN suppression to depression, this has not been investigated in a healthy population. This study examined potential gender differences in the time required to switch from the DMN to the CEN in a healthy sample. Additionally, it investigated whether switching time was positively related to brooding rumination and whether this relationship differed between genders. Lastly, it explored whether functional connectivity (FC) between the DMN and the subgenual anterior cingulate cortex (sgACC) was related to brooding rumination. Results indicated a faster DMN-CEN switch in men compared to women. No relationship was found between switching time and brooding rumination in either men or women. Lastly, brooding rumination showed no relationship with sgACC-DMN FC. This study proposes a slower DMN-CEN switch as a possible neural mechanism for higher rates of depression and relapse proneness in women compared to men. Moreover, it suggests that DMN suppression may not underlie brooding rumination as a risk factor for MDD. Researchers developing preventive measures for depression aimed at reducing brooding rumination may consider targeting other neural mechanisms than DMN suppression. Future research should explore these alternative neural mechanisms to support the development of preventive measures for the onset and relapse of depression.Show less

Als deze zelfregulatie niet tot stand komt, spreken we van zelfregulatie falen. Hierbij hoort ook het ervaren van een setback, een terugval in het naleven van een gedragsdoel. Om de kans op setbacks zo klein mogelijk te maken, moeten we begrijpen hoe individuen reageren op deze setbacks. In deze thesis wordt onderzoek gedaan naar het belang van gedragsdoelen en welke psychologische constructen invloed hebben of worden beïnvloed door het ervaren van een setback. Deze thesis onderzoekt daarnaast het verschil tussen approach-oriented en avoidoriented doelen in relatie tot subjectief succes bij gedragsverandering. Vanuit de literatuur werd verwacht dat doelen met betrekking tot fysieke gezondheid de belangrijkste gedragsdoelen waren. Daarnaast werd als hypothese gesteld dat approach-oriented doelen meer subjectief succes opleveren dan avoid-oriented doelen. Methoden. Met een steekproef van 167 participanten werden verschillende statistische analyses toegepast om antwoord te geven op de drie onderzoeksvragen. De resultaten duiden op een significant onderscheid tussen beide typen doelen, waarbij approach-oriented doelen aanzienlijk hogere gemiddelde scores op subjectief succes vertonen dan avoid-oriented doelen. In de context van de eerste onderzoeksvraag blijkt dat het verhogen of reguleren van wekelijkse sportactiviteiten het meest voorkomende doel is, terwijl het verhogen of reguleren van gezonde voeding het daaropvolgende meest gangbare doel is. De tweede onderzoeksvraag wijst op een algemene positieve perceptie van doelbereiking onder deelnemers, waarbij approach-oriented doelen, zoals het verhogen van gezonde voeding, meer succesvol lijken dan avoid-oriented doelen, zoals het reduceren van alcoholinname. Echter tonen de resultaten aan dat deelnemers die zich richten op het verhogen of reguleren van sportactiviteiten zich over het algemeen niet significant succesvoller voelen dan degenen die zich concentreren op het verhogen of reguleren van gezonde voeding, Conclusie. De bevindingen suggereren dat het streven naar gewenste resultaten een verhoogd gevoel van succes teweegbrengt in vergelijking met het vermijden van ongewenste resultaten. Dit impliceert praktische implicaties voor interventies gericht op gedragsverandering, waarbij een nadruk op approach-oriented doelen een effectieve strategie lijkt te zijn. Echter wijst dit onderzoek op enkele beperkingen, zoals een beperkte steekproefomvang en de mogelijkheid van vertekening door zelfrapportage. Toekomstig onderzoek zou baat hebben bij een representatievere steekproef en longitudinale ontwerpen om een dieper inzicht te verschaffen in deze dynamiek.Show less

Om de negatieve gevolgen van externaliserend gedrag te voorkomen, is het belangrijk om de mechanismen erachter beter te begrijpen. Het doel van dit onderzoek is om te kijken of deze relatie daadwerkelijk bestaat en of een laag zelfbeeld deze relatie versterkt. In een cross-sectioneel onderzoek met 80 kinderen en hun ouder(s), werden ouderlijke kritiek, het externaliseren van de kinderen en het zelfbeeld van de kinderen gemeten aan de hand van vragenlijsten en een interactietaak. De resultaten toonden dat er geen relatie is tussen kritiek van de ouders en externaliserend gedrag van het kind. Ook versterkte een laag zelfbeeld deze relatie niet. Het blijft echter nog de vraag op welke manier deze drie variabelen met elkaar in verband staan en of factoren zoals het geslacht van het kind of verschillen tussen de ouders hier iets mee te maken hebben. Onderzoek hiernaar zou meer duidelijkheid geven rondom dit vraagstuk.Show less

EMSs have been categorized into five broader schema domains. Transdiagnostic depressive symptoms entail depressive symptoms observed across various psychological disorders. We studied the relative contribution of the five EMS domains on transdiagnostic depressive symptoms in a cross-sectional within-subjects design. The sample consisted of students from Leiden University (N = 125) participating for course credit or monetary rewards, of which 91.2% were assigned the sex female at birth and 8.8% male (median age = 19, IQR = 2). Participants completed measures of the Young Schema Questionnaire 3 - short form (YSQ-S3) and the DSM-5 self-rated level 1 cross-cutting symptom measure – Adult (DSM-XC). Pearson correlations were inspected between each EMS domain and transdiagnostic depressive symptoms. A multiple regression analysis including the total scores of the five EMS domains as predictors was carried out. Individually, the EMS domains Disconnection & Rejection, Impaired Autonomy & Performance, Impaired Limits, Other-directedness, and Overvigilance & Inhibition were positively associated with transdiagnostic depressive symptoms (rs .451, .365, .289, .298, .345, p < .001), as hypothesized. The joint effect of the five EMS domains was positively associated with transdiagnostic depressive symptoms (Adj. R2 = .18, F(7, 117) = 4.88, p <.001). Interestingly, when holding the other domains constant, only the Disconnection & Rejection domain significantly predicted transdiagnostic depressive symptoms in the model (β = .44, 95% CI [.15, .74], p = .004). The domain groups the beliefs about expectations that one’s needs for security and stability will not be met predictably. Our findings suggest that each EMS domain is positively related to transdiagnostic depressive symptom severity in a university student population. The Disconnection & Rejection domain, relative to the other four domains, seems to uniquely contribute to transdiagnostic depressive symptoms. Future research could test whether identifying and changing the EMSs someone has in psychotherapy could reduce their transdiagnostic depressive symptoms across different psychological disorders. It remains a question if paying specific attention to the Disconnection & Rejection domain in psychotherapeutic treatment could improve the reduction of transdiagnostic depressive symptoms.Show less

Although the CAPS-5 was developed and validated in Western populations, many clinicians and researchers also use it to assess PTSD in non-Western refugee populations. In this study we investigated whether PTSD as assessed with the CAPS-5 has the same structure and meaning across trauma-exposed, treatment-seeking individuals with either a Dutch (i.e. Western) background or a non-Western refugee background. Method: We evaluated commonly accepted DSM-5 PTSD factor models and tested different levels of measurement invariance (configural and scalar invariance) in a clinical sample of non-Western refugee patients (N = 710) and Dutch patients (N = 1162) suffering from prolonged complaints of psychotrauma, using confirmatory factor analyses (CFA). Results: CFAs showed that the Hybrid model of PTSD fit the data best in the Dutch and non-Western refugee subsample, as well as in the combined sample, indicating that configural invariance was met. The model representing scalar invariance showed a worse fit compared to the model representing configural invariance, indicating that factor loadings and/or symptom severity differed between the subsamples. Further investigation showed that this result could mainly be attributed to non-Western refugee patients often manifesting higher scores on the CAPS-5 items than Dutch patients. Conclusions: Non-Western refugee patients showed a similar structure of DSM-5 PTSD symptoms as Dutch patients. Furthermore, the relative contribution of the majority of symptoms to its belonging symptom cluster was similar between non-Western refugee patients and Dutch patients. This meant that both groups understood these symptoms in the same way. However, non-Western refugee patients often manifested a higher symptom severity than Dutch patients.Show less

Higher levels of synchrony, or the level of correspondence in behavior between parents and their children, is related to better social and emotional developmental outcomes for the children. In total, 69 parents and their 12-months-old baby’s participated in an eye-tracking study, in which an animation was shown that depicted a situation, wherein a “baby figure” shows distress after it is separated from a “parent figure”. This so-called separation segment of the animation was followed by the so-called response segment, wherein either a reunion or further separation of the two characters was shown. Both the parental sensitivity during free-play and the relative fixation duration to the “parent figure” in regards to the “baby figure” were measured. Within this study, no relationship between parental sensitivity and the level of correspondence in monitoring strategies has been found. Moreover, there was no proof for the statement that overall the monitoring strategies of parents and their children correspond with each other while watching animations that depict a social interaction. The baby’s tend to look more at the “parent figure” than their parents do. The focus on the “parent figure” increased from the separation segment to the response segment, for both the parents and their baby’s, although this increase in fixation is bigger for the parents than for their baby’s. These results imply that further research into the possible precursors or influences on the correspondence of behaviors within parent-child dyads is necessary.Show less

Selective mutism shares similarities with social anxiety disorder. The cause of selective mutism is unknown, although several factors appear to be involved. The current study examined whether children with selective mutism have deficits in their inhibition and mental flexibility. Using parent questionnaires and a neurocognitive task for the children, inhibition in daily life, inhibition on a cognitive task, flexibility in daily life, flexibility on a cognitive task, and the social anxiety of both silent and non-silent children were assessed. A total of 33 children between four and six years old participated in the study, including 16 silent and 17 non-silent children. The results imply that inhibition and flexibility as behavioral characteristics are not the same constructs as inhibition and flexibility as cognitive functions but should be used to complement each other. Silent children were found to have more difficulty suppressing their responses on a cognitive task compared to the non-silent group. This difference was not observed for inhibition measured in daily life. It is suggested that silent children may struggle to suppress cognitive reactions for instance anxious thoughts in new situations while being capable of controlling impulses at a behavioral level. Additionally, silent children did not differ in their cognitive task-based mental flexibility from non-silent children, but they did differ in their mental flexibility in daily life. One explanation for this difference may be that environmental influences, such as stress, may prevent a child from effectively applying certain skills. Furthermore, in the present study of young children mental flexibility skills in daily life explained about a significant portion of the variance in social anxiety.Show less

Higher intake of vegetables appears to aid in preventing overweight. Since food preferences form before the age of 2, understanding factors influencing children's vegetable intake is crucial. Parental vegetable intake predicts children's vegetable intake, but research on the mother-child relationship in this context is limited, especially regarding young children under the age of 2. This study examines the relationship between maternal and child vegetable intake among children aged 11 to 14 months, exploring the potential moderating roles of maternal body mass index (BMI) and exclusive breastfeeding. Method: Data were drawn from the "Baby's First Bites" study, involving 240 mother-child pairs from the Netherlands, with 121 pairs included in this analysis. Children's vegetable intake was measured using Compl-eat, while mothers' vegetable intake was measured using the Food Frequency Questionnaires (FFQ). One multiple regression and two moderation analyses were conducted, with the mother's education level included as control variable. Results: Results indicated no significant association between maternal and child vegetable intake. Moderation analyses revealed that neither maternal BMI nor exclusive breastfeeding moderated this relationship. Even after accounting for the mothers' educational levels, the results remained unchanged. Discussion: These results are contrary to the hypotheses. Possible explanations for these findings include the young age of the children in this study, which may prevent them from applying modeling as a possible working mechanism between maternal and child vegetable intake. Also, methodological limitations such as the use of Compl-eat and the limited duration of exclusive breastfeeding could explain the lack of an observed association. Future research could investigate whether altering methodologies reveals a previously unnoticed association between mothers' and children's vegetable intake, and explore the underlying mechanisms of this relationship to clarify the effectiveness of increasing mothers' vegetable intake as a preventive measure against childhood overweight.Show less

Adolescents are vulnerable to developing SUD and as substance misuse has a neurodegenerative effect, it is important to understand the mechanics behind SUD in adolescents. This current study consisted of 334 adolescents with SUD, with the age ranging from 16 to 23 years old. Cannabis was the primary substance for which participants entered treatment (63.5%), followed by alcohol (17.7%) and cocaine (11.1%). The WHODAS-2.0 was used to measure Qo. To measure self-reported stress the DASS-21 was used, whereas hair cortisol concentration (HCC) was used to measure chronic stress. The YIT-Q was used to measure the ACEs and finally, the MATE-Y was used to measure the SUD severity. HCC is a proposed biomarker for chronic stress. As it is relatively new, HCC has not yet been investigated for adolescents with SUD. Two mediations were investigated, one with HCC as variable for stress, and one with self-reported stress. Study findings showed that the relationship between ACEs and QoL was fully mediated by self-reported stress, whereas no mediation was found for HCC. This indicates a difference in HCC and self-reports as a measure of stress and highlights the importance for continued research into HCC as biomarker for chronic stress. A recommendation for future research is to further investigate the usability of HCC as a biomarker for chronic stress, for example by continuing investigating HCC in adolescents with SUD, as current study was the first to do so. Additionally, it is recommended to repeat the mediation analysis in a broader population to investigate whether HCC does have a mediating role in other populations.Show less
