This study assessed the impact of different forms of child abuse (physical, emotional, sexual) on depressive symptoms in patients with MDD and a recent history of victimization, and whether gender moderates this relationship. Additionally, it investigates whether Internet Emotion Regulation Training (iERT) as an addition to Treatment as Usual (TAU) can reduce emotion regulation difficulties and depressive symptoms in the same population. 153 patients filled in questionnaires and the hypotheses were tested by a hierarchical regression analysis and two repeated measure ANOVAs. Regarding the first research question, a significant association was found between depression and physical- and emotional child abuse, but not sexual abuse. This effect was not moderated by gender. Regarding the second research question, no significant effect was found of adding iERT to TAU on either emotion regulation difficulties or depressive symptoms.Show less

Parental factors related to sensitive parenting are depression and parental self-efficacy. The aim of this study was to explore the relationship between depression and sensitive parenting, and whether parental self-efficacy mediates this association. Participants were 17 Dutch mothers and 4 Dutch fathers of children aged 3-5 years. Parents played 5-10 minutes with their child during two measurement moments, while the researcher was present through a Microsoft Teams connection. A video of the playing was recorded. In between the two measurement moments, parents completed the Center for Epidemiologic Studies Depression-questionnaire (CES-D) and the Me as a Parent-questionnaire (MaaP). Afterwards, the video recordings were encoded according to the Ainsworth sensitivity scale. Only the relation between depression and sensitivity was significant, where depression was positively related to sensitivity. There was no indication found for a mediational role of parental self-efficacy in the relation between depression and sensitivity. Explanatory theories, limitations and practical implications were discussed. Future research will have to show which other factors can explain these unexpected findings.Show less

The People’s Action Party (PAP), which has been in constant rule for over 65 years, has sought to maintain their hegemony and “protect the country” by actively limiting citizens' influence over politics and policies, mainly through the development of legal frameworks repressing dissent across different parts of society. By using theories on contentious politics, state repression, and the political opportunity structure, as well as a qualitative content analysis of Singapore’s laws on dissent, this thesis addresses the following research question: What are the strategies employed by the Singaporean government to repress and prevent dissent, and how do these strategies impact the political opportunity structure for contentious politics? Summarizing the findings, this thesis concludes that the state has built an extensive framework of restrictive laws covering all forms of society, rather than explicitly focusing on certain aspects, which has caused opportunities for dissenting citizens to employ methods of contentious political action to achieve their aims of influencing state policies to be exceptionally limited.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

Onderzoek heeft aangetoond dat mensen regelmatig niet optimaal reageren op een terugval. Ondanks veel studies naar self-efficacy en doeloriëntaties bij setbacks, ontbreekt het begrip van hoe deze factoren elkaar beïnvloeden in het specifieke geval van de drie deelconstructen van self-efficacy: taak self-efficacy, onderhoud self-efficacy en herstel self-efficacy. Dit onderzoek onderzocht de invloed van approach- en avoidance-doelen op deze deelconstructen bij mensen die een setback hebben ervaren. Met behulp van een online vragenlijst over gedragsdoelen op het gebied van voeding, alcohol, nicotine, fysieke activiteit, schermtijd, gelduitgave en tijd voor hobby’s of ontspanning, zijn de participanten gevraagd naar hun gedragsdoelen en de setbacks die zij hebben ervaren. De respondenten (N=152) waren tussen de 17-30 jaar en streefden minstens een van deze gedragsdoelen na. Drie afzonderlijke t-testen vergeleken de deelconstructen van self-efficacy tussen approach- en avoidance-doelen. Resultaten toonden aan dat deelnemers met een approach-doel een hogere taak en onderhoud self-efficacy hadden na een setback dan degenen met een avoidance-doel. Herstel self-efficacy werd niet beïnvloed door doeloriëntatie en had een lagere correlatie met taak en onderhoud self-efficacy. De relatie tussen doeloriëntatie en de deelconstructen van self-efficacy bleek daarmee niet eenduidig. Mogelijke verklaringen voor deze bevindingen kunnen liggen bij individuele verschillen en andere psychologische mechanismen die niet zijn onderzocht in deze studie. Deze bevindingen kunnen worden gebruikt voor het ontwikkelen van effectievere interventies. Daarnaast benadrukken deze bevindingen het belang van verder onderzoek naar de afzonderlijke deelconstructen van self-efficacy en hun relatie bij setbacks.Show less

De verwachte stijgende prevalentie van ouderdomsziektes door vergrijzing levert een behoefte aan een oplossing voor de hoge werkdruk bij zorgpersoneel en single item vragen verminderen werklast bij zorgpersoneel en patiënt. Het doel van dit onderzoek was om te onderzoeken of ervaren functioneren en ervaren gezondheid twee verschillende constructen zijn. De hypothese was dat dit twee verschillende constructen zouden zijn. Deze zouden naast elkaar uitgevraagd kunnen worden in gezondheidsmonitors en gezondheidsevaluatielijsten in de zorg om aanvullende informatie te geven over kwaliteit van leven en welzijn van een patiënt. Uit verschillende bestaande gezondheidsmonitors is een vragenlijst samengesteld. Hieraan zijn items over demografische kenmerken en de ervaren gezondheid en zelf ontworpen ervaren functioneren vraag toegevoegd. De vragenlijst bestond uit 47 vragen en is verspreid via sociale media. De dataset bestond uit 281 respondenten, waarvan 42,3 % man, 55,9% vrouw en 1,1% non-binair. 65,5% van de respondenten had geen ervaring met een langdurige ziekte, 22,8 % met één langdurige ziekte en 11,7% met twee of meer langdurige ziekten. De correlaties tussen drie van vijf items van de EQ-5D5L (mobiliteit, pijn/ongemak en angst/somberheid) en ervaren functioneren waren significant verschillend met de correlaties tussen de items en de ervaren gezondheid vraag. Ook de EQ-VAS correleerde significant verschillend. Hoewel ervaren functioneren en ervaren gezondheid niet significant verschillend correleerden op elk item van de EQ-5D5L, reageerden ze niet identiek. Dit kan een aanwijzing zijn dat ervaren functioneren en ervaren gezondheid twee verschillende constructen zijn. Er is meer onderzoek nodig naar de domeinen waarop ervaren functioneren en ervaren gezondheid wel dan niet verschillen.Show less

Echter is het effectief vormgeven van woordenschatonderwijs aan deze doelgroep een uitdaging voor basisscholen. Dit onderzoek richt zich op het identificeren van effectieve strategieën voor het geven van woordenschatonderwijs aan NT2-leerlingen in kleuterklassen alsmede onderzoek naar het gebruik van deze strategieën op een specifieke basisschool. Middels een literatuurstudie zijn er drie principes vastgesteld die bijdragen aan effectief woordenschatonderwijs: 1. Integreer de moedertaal in het onderwijs, 2. Verhoog de hoeveelheid verbale interactiemomenten 3. Werk met directe instructiemomenten. Uit semi-gestructureerde interviews met vijf werknemers van een basisschool die zich met het kleuteronderwijs bezighouden blijkt het volgende. Als eerste heeft de school de integratie van de eerste taal in haar onderwijs nog niet in grote mate geïmplementeerd. Daarnaast blijkt dat leerkrachten actief didactische impulsen geven om interactie tussen leerlingen te bevorderen. Ten slotte wordt vastgesteld dat de school bekend is met het concept van directe instructiemomenten, maar dat er niet altijd voldoende tijd beschikbaar is om dit toe te passen. Deze bevindingen bieden inzichten voor leerkrachten en ondersteunend personeel om woordenschat effectiever te implementeren voor NT2-leerlingen in kleuterklassen.Show less

Problematic behaviour is often caused by pain and places a heavy burden on both professional and family caregivers. Especially since family caregivers are often overlooked as a factor in care. This study therefore investigates the effectiveness of the STA OP! method (SOM), a stepwise approach to address problematic behaviour and pain in individuals with dementia, as well as how the efficacy of SOM is moderated by family involvement. The study, conducted within the CARED-4 project, utilizes a quasi-experimental longitudinal design with measurements at baseline, 3 months, and 6 months after implementing SOM. It included 84 residents with dementia from 10 Dutch nursing homes units paired with their family caregivers. Problematic behaviour was examined using the Neuropsychiatric Inventory Questionnaire (NPI-Q) and family involvement was examined through a tailored questionnaire. Analysis was performed with RM Anova for problematic behaviour and family involvement and a general linear model for the moderation of SOM by family involvement. Results indicated that SOM effectively reduces problematic behaviour overall (F(2,55) = 3.81, p = 0.028), after 3 months (Mean Difference = 5.47 SE= 1.97, p = 0.007), but not after 6 months (Mean Difference = 5.70 SE = 3.36, p = 0.095). Family involvement did not change overall (F(1.62,30) = 2.12, p = 0.138). Accordingly, family involvement did not moderate the impact of SOM on problematic behaviour (F(2) = 1.43, p = 0.243). Despite methodological challenges mainly due to missing data, the study takes a first step towards understanding how the effectiveness of SOM interacts with family involvement. So, although family involvement did not moderate a significant reduction in problematic behaviour, the efficacy of SOM has further been established.Show less

One way of improving students’ reading comprehension could be by providing feedback to students while they answer questions about a text. To use feedback efficiently in the future, it’s important to know how elaborate effective feedback should be. Considering this, the current study examined the relation between feedback and the use of reading strategies in general, and for the use of reading strategies while reading a text. Moreover, the relation between the amount of information provided in the feedback and the use of reading strategies was examined. Experimental data of 97 participants aged 10 and 11 years (52.6% boys, M = 10.45, SD = 0.52) was collected using questionnaires, namely the Metacognitive Awareness of Reading Strategies Inventory and the Task-Specific Strategy Self-Report. Participants were pre- and post-tested and had three intervention sessions. They were randomly assigned to a condition, namely no feedback, short feedback, or elaborate feedback. During the intervention sessions, participants had to read a text, and answer questions about the text. Depending on their condition, they either received feedback or not. If they did, the amount of information in the feedback differed. Every session ended with a questionnaire. Using SPSS, two repeated measures ANOVA were completed. According to the results, there was no relation between feedback and the use of reading strategies. Furthermore, no differences were found for the different amounts of information in feedback and the use of reading strategies. The biggest limitation of the current study was the lack of a motivational component in the used intervention. Therefore, future research should use motivation as part of the intervention to investigate if feedback could help in improving the use of reading strategies for youth aged 10 to 11.Show less

Although fatigue is the most common daytime symptom of insomnia, it is still largely unknown which underlying components are associated with fatigue in a broader population of insomnia patients. Previous literature stated that dysfunctional sleep-related beliefs (DSRB) and pre-sleep arousal (PSA) could explain the relationship between insomnia and fatigue. Additionally, subjective sleep characteristics, such as insomnia severity, number of nocturnal awakenings (NoA) and sleep efficiency might also be components of this relationship. This study aimed to investigate how these factors affect fatigue in a broad medical population with insomnia. It was hypothesized that more disturbed sleep-related psychological factors and subjective sleep characteristics were associated with increased fatigue. This cross-sectional study, derived from the ongoing TIMELAPSE study, consisted of 154 participants. Participants completed questionnaires assessing fatigue (Checklist Individual Strength-20), DSRB (Dysfunctional Beliefs and Attitudes about Sleep-16), PSA (Pre-Sleep Arousal Scale), and insomnia severity (Insomnia Severity Index). The Consensus Sleep Diary tracked NoA and sleep efficiency daily for one week. Two multiple regression analyses were performed to assess the relationship between sleep-related psychological factors (DSRB, PSA), subjective sleep characteristics (insomnia severity, NoA, sleep efficiency) and fatigue. Age, gender, and depression were included as controlling variables. Results showed that DSRB (β = .174, p = .027), PSA (β = -.160, p = .036), and insomnia severity (β = .243, p = .002) were factors associated with fatigue in insomnia patients. More severe DSRB and higher insomnia severity predicted elevated levels of fatigue. Contrary to expectations, PSA was negatively associated with fatigue. Lastly, NoA and sleep efficiency were not related to fatigue. This study uncovered connections between more severe DSRB, lower PSA, and higher insomnia severity that led to higher levels of fatigue. The current study suggests that improvements in DSRB and reducing insomnia severity may reduce fatigue of insomnia patients with long-term medical conditions. Sleep interventions should emphasize on challenging these DSRB. Future research is needed to examine the complex relationship between PSA and fatigue, as well as whether changes in DSRB during CBT-I treatment reduce fatigue symptoms in this population.Show less

Using an experimental between-subject design with online surveys, 225 UK-based participants were randomly assigned to control or gain-framed message conditions. The gain-framed message conditions included health-gain and work-performance-gain. Surprisingly, participants in the control group showed more detachment than those in the message conditions, challenging previous literature. Contrary to the expectations, the moderating effects of financial stress and message trust were not found. Despite limitations, such as a sample limited to the UK and the use of a questionnaire, the research contributes new insights into messaging effects on preventive behaviors. It underscores the importance of context and individual differences in message reception and behavior, and urges future research to consider the effectiveness of gain-framed messages in motivating people to adopt certain behavior.Show less

Dit onderzoek richt zich specifiek op het verkennen van de verschillen tussen twee vormen van AD, namelijk Early-Onset Alzheimer's Disease (EOAD) en Late-Onset Alzheimer's Disease (LOAD), met als doel het verbeteren van classificatiemodellen. We hebben vier classificatiemodellen ontworpen, elk gericht op specifieke hersengebieden die mogelijk atrofie vertonen, met Model 1 en 2 gericht op respectievelijk LOAD en EOAD, Model 3 als een gecombineerd model en Model 4 dat de algehele hersenatrofie omvat. Deze modellen zijn geanalyseerd aan de hand van Area Under the Curve (AUC) en zijn ontwikkeld met behulp van logistische regressie en LASSO om de meest relevante variabelen te selecteren. Onze bevindingen suggereren dat EOAD en LOAD verschillende neuropathologische patronen vertonen, waarbij EOAD mogelijk wordt gekenmerkt door specifiekere neuropathogenese patronen, terwijl LOAD meer uniforme hersenveranderingen vertoont. Model 3, dat specifieke hersengebieden combineerde, presteerde het beste bij het classificeren van beide groepen, terwijl Model 4, dat alle hersengebieden omvatte, een lagere classificatie-accuratesse vertoonde voor EOAD. Deze resultaten benadrukken dat AD patiënten geen homogene groep zijn en benadrukken het belang van gedifferentieerde diagnostische benaderingen om rekening te houden met de heterogeniteit binnen deze aandoening.Show less

Loneliness, conceptualized as a subjective feeling of social isolation is often found comorbid with apathy; one’s reduced motivation to put in effort for others’ benefit relative to one’s own benefit. Although all three variables demonstrate a relationship to one another, research remains scarce regarding their shared impact. However, findings show a positive influence of prosocial behaviors on social connections, consequently decreasing experiences of isolation as well as apathy. This investigation aims to uncover the potential mediating effect of prosocial behavior on the bidirectional relationship of loneliness and apathy. To fill the gap in the literature, assessing both models helps highlight intervention approaches aiming to effectively break the cycle – ultimately improving well-being. Higher levels of loneliness are expected to indicate higher levels of apathy, whereas prosocial behaviors may mediate and limit the negative affect. Ultimately, it is also expected higher levels of apathy lead to higher levels of loneliness, with prosocial behavior possibly mitigating this negative affect. 287 participants underwent a behavioral task assessing their prosocial tendencies, as well as questionnaires measuring their level of loneliness and apathy. Both mediation analyses revealed a significant total effect between the variables. This was indicative of a negligible mediating role of prosocial acts. These results underline the specific gaps left for future research, ranging from exploring the nuanced relationships and contextual factors involved affecting the constructs over time.Show less
