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

Women in particular face heightened discrimination and sexual violence. Holding roughly half of the world’s biodiversity and 23% of global forests, Latin America plays a central role within this discussion (OECD 2023). The combination, then, of Latin America and Indigenous Peoples is paramount. This research embarks on the issue of climate change, and the resulting “Energy Transition”, starting with a broad lens and zooming into one specific and crucial component: the Indigenous world. Therein, Indigenous female positionality within the Energy Transition, and specifically the impacts that lithium mining have on them is discussed. This thesis aims to elucidate how green initiatives can have negative consequences, providing information which may be utilized to ensure that the transition does not “perpetuate the violations and abuses currently plaguing extractive and other fossil-fuel related projects” (United Nations, General Assembly 3, 2023). It does so by positing: “How have Indigenous women in Bolivia been impacted by the “Energy Transition”? The inspiring stories of empowered women that follow provide an insight into the resilience and determination that a historically overlooked societal group has, and continues to show in Bolivia. Key works of Decolonial Feminism and Colonialism are used throughout.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

We aimed to quantify the risk of comorbid disorders in SUD youth with ACE-history. Additionally, we aimed to examine relations between ACEs, overall household experience, and general distress. We used cross-sectional YIT-study data from interviews with Dutch youth (aged 16-22) upon SUD treatment entry for cannabis, alcohol, or stimulant use. We measured ACE-types experienced up until 15 years of age, past-year DSM-5 disorders, general distress (DASS-21), and overall household experience rating. Logistic regressions quantified relations between ACE sum score and anxiety, depressive, behavior, and any disorder. Higher ACE sum scores related to increased risks for a(n) anxiety (OR = 1.12, highest odds = 2.84; χ2(1) = 6.71, p < .010; Nagelkerke R2 = 0.2), depressive (OR = 1.21, highest odds = 5.43; χ2(1) = 18.11, p < .001; Nagelkerke R2 = 0.6), behavior (OR = 1.20, highest odds = 5.24; χ2(1) = 17.41, p < .001; Nagelkerke R2 = 0.6), and any (OR = 1.25, highest odds = 7.58; χ2(1) = 17.26, p < .001; Nagelkerke R2 = 0.7) disorder. Exploratory analyses revealed that frequency of parental fighting, being hit/abused, getting belittled, emotional neglect, physical neglect, insufficient household income, long parental sickness, and overall household experience positively related to DASS-21. In a hierarchical regression analysis with all ACEs and overall household experience, only emotional neglect related to DASS-21 (B = 3.68, t(373) = 2.41, p = .017). Overall household experience did not improve the model (F(12) = 3.51, p < .001; R2change < .001). In hierarchical regression analyses containing ACE sum score and overall household experience, overall household experience was not uniquely related to DASS-21 (t = -0.22, p = .824; R2change < .01). In conclusion, ACEs relate to comorbid disorders in SUD youth. Our exploratory research suggests that ACE frequency might influence this relation, while overall household experience does not further explain this relation. Further research should investigate which ACE measures (a.o., type, frequency) strongly relate to SUDs and psychopathology and examine improved treatment options.Show less

Het is een vorm van huiselijk geweld waar nog relatief weinig over bekend is. Daarom is de organisatie Enver bezig met het opstellen van een nieuw protocol voor het werken met deze problematiek. In dit adviesrapport staat beschreven wat de kennis over dwingende controle is binnen Enver en wat de behoeften zijn van medewerkers in het verbeteren van de kennis en de aanpak. Hierbij is gezocht in reeds bestaande literatuur naar de definitie, de mogelijke gevolgen en waarop gelet moet worden bij het signaleren van dwingende controle. Daarnaast is onderzocht welke kennis de medewerkers van Enver al hebben en waar eventuele behoeften liggen, door middel van een vragenlijst die is verspreid onder de medewerkers van Enver. Uit de resultaten van de literatuur komt naar voren dat er verschillende definities worden gehanteerd voor dwingende controle. De definitie van Stark (2007) is het meest passend. Hierin definieert Stark dwingende controle als een strategische reeks onderdrukkend gedrag die verder gaat dan fysiek geweld. Daarnaast zijn in het literatuuronderzoek ook resultaten gevonden over de signalering van dwingende controle. Hieruit is een helder dader- en slachtoffer profiel naar voren gekomen. Verder blijkt in de literatuur geen consensus te zijn over concrete richtlijnen van signalering van dwingende controle. Wel zijn twee recente gidsen (Instrumenten Voor Opsporing van Dwingende Controle, z.d.), een gespreksinstrument (DASH; Myhill & Hohl, 2019) en een training voor professionals gevonden (Geweldspatroon van Dwingende Controle in (Ex-)Partnerrelaties - het Verschil Tussen Wat Er Gebeurt op het Toneel en in de Coulissen | RINO Groep Utrecht, z.d). Als laatste is uit de literatuur gebleken dat er verschillende negatieve gevolgen zijn op persoonlijke en relationele vlakken voor partners. Ook kunnen er gevolgen zijn voor een kind. Uit het empirisch onderzoek blijkt dat, als er gekeken wordt naar de afdelingen, ‘gedragswetenschappers’ de hoogste score behalen en deze significant hoger scoren dan de ‘jeugdhulpverleners’. Verder is naar voren gekomen dat op het cluster gevolgen beter wordt gescoord dan op de clusters signaleren en gedragskenmerken. Wat betreft de behoeften blijkt dat medewerkers behoefte hebben aan duidelijke richtlijnen binnen de organisatie over hoe te handelen in het geval van dwingende controle. Het advies voor Enver is om richtlijnen op te stellen voor gepaste hulpverlening na signalering van dwingende controle en eventuele bijscholing voor afdelingen te overwegen.Show less

Avenues for discourse between governments and the public are provided through digital platforms. This is done with the intent of establishing a citizen-centric environment. In South Korea, succeeding democratization in the late 1970s and 1980s, citizens as integral to public administration came to the forefront in contemporary urban life. Seoul and Incheon represent two major smart cities, for which digital technologies are the foundation. In South Korea, swift developments in e-governance have consequently resulted in a research gap. To challenge this, the study considers the primary digital government platforms of Seoul and Incheon. Through a content analysis, the effectiveness of the platforms in building social capital and citizen-centricity is deduced. Then, the outcome is interpreted through a revised ladder of citizen participation. The results signify various opportunities and flaws in its e-governance. In Seoul, connectivity as a means of boosting civic empowerment is addressed effectively. Still, citizens are limited in the co-creation process of daily urban policies. In Incheon, basic elements of open data and communication are addressed. Yet, consequences of citizen’s input remain largely unaddressed. South Korean policy makers may therefore take note of these repercussions to establish a more effective and efficient digital platform apparatus.Show less

Empirical studies have demonstrated that the content of parental verbal information regarding social situations plays a crucial role in shaping children’s development of social fear. Specifically, verbal threat (versus safety) information by the parent regarding novel stimuli significantly influenced children’s reported fear of the social scenario. The current study aims to further investigate whether such verbal threat and safety messages affect children's reported fear in social situations. Additionally, the study explores the potential moderating influence of parental social anxiety on this relationship, as evidence suggests that socially anxious parents convey more negative information regarding novel stimuli, thereby amplifying children's fear beliefs. A total of 69 children (mean age = 11.92 years; 38 girls) received standardized threat and safety information regarding a stranger from their primary caregivers. Subsequently, children engaged in three social tasks with each stranger and reported their fear beliefs about the stranger at the end of the social tasks. Results indicate significantly higher fear beliefs among children who received threat information compared to safety information regarding the stranger. However, parental social anxiety did not moderate the effects of negative verbal information on children’s reported fear beliefs. These findings underscore the role of negative verbal information transmission in children's acquisition of social fears while highlighting the complexity of factors within social anxiety that could contribute to the intergenerational transmission of these fears.Show less

Dit wijst op de activatie van het parasympathische zenuwstelsel. Ademhalingsoefeningen blijken vooral effectief te zijn bij onder andere angststoornissen. Bij deze stoornissen ligt de hartslagvariabiliteit gemiddeld hoger dan in de gezonde populatie. Een groot deel van de mensen met een angststoornis zoekt geen hulp omdat ze een hoge mate van angst ervaren bij sociaal contact. Vooral jongeren blijken hier last van te hebben. Om toch deze groep te helpen, kunnen er behandelingstechnieken worden ingezet waarbij er geen sociaal contact nodig is. In deze studie is er onderzoek gedaan naar het effect van de ademhalingstechniek ‘slow breathing’ bij jongeren met sociale angst. Dit is onderzocht bij een subklinische populatie om te kijken of de ademhalingstechniek ook bij deze groep effectief is. De meeste onderzoeken zijn namelijk uitgevoerd bij de gezonde of klinische populatie. Om te kijken of de ademhalingsoefening effectief is, is tijdens een sociaal stressvolle taak de hartslagvariabiliteit gemeten. Uit de resultaten is gebleken dat slow breathing significant de hartslagvariabiliteit van de interventiegroep verlaagt. Ook is er een significant verschil gevonden in de hartslagvariabiliteit tussen de interventie- en controlegroep na het uitvoeren van de oefening. De ademhalingstechniek is dus effectief bij het op de korte termijn verlagen van de hartslagvariabiliteit bij jongeren met sociale angst. In vervolgonderzoek is het interessant om te kijken naar het langetermijn effect van de slow breathing oefening.Show less
