To protect their children from these dangers, parents might implement rules or restrictions of phone use for their teenagers. These restrictions can keep them away from risky apps or reduce their time online. However, it is unknown if these restrictions result in less encounters of dangerous situations. This study focusses specifically on exposure to sexual content online. The aim of this study is to find out if there is a relation between phone restrictions someone might have had while growing up and exposure to sexual online content. Participants were asked to anonymously fill in an online questionnaire about their online experiences and possible phone restrictions. Using this data, an ordinal regression analysis was used to examine the relation between the presence of phone restrictions and the exposure to sexual content online. In addition, this study looks if there is a relation between what type of restriction someone might have had and the type of online exposure to sexual content: unwanted exposure and wanted exposure for the participant. The results of this study have found no significant effect, implying there is no relationship between the presence of phone restrictions and exposure to online sexual content. Furthermore, no evidence was found to indicate a relationship between the type of restrictions and wanted exposure to online sexual content. Only a significant, positive relationship was found between a limited screen time and wanted exposure to online sexual content.Show less

At ‘de Jeugdbeschermingstafel’, an assessment is conducted to determine the necessity of conducting a counsil investigation (‘raadsonderzoek’). It was examined whether this decision-making differs between families with a high or low socioeconomic status who are going through a complex divorce. The main question of study was: ‘To what extent is a complex divorce related to a custody investigation, and is this relationship moderated by the socioeconomic status of parents?’ To investigate this question a correlational research design was used. For this study, various research requests from ‘de Jeugdbeschermingstafel’ across the Netherlands were investigated. These research requests had been anonymized, read and coded. Seventy-one requests of investigations have been utilized. The distribution between complex divorce and non-complex divorce cases, as well as between socio-economic disadvantage and no socio-economic disadvantage could be improved. It was expected that a counseling investigation would be chosen more often for families going through complex divorce than for families without complex divorces, particularly in cases of high socioeconomic status, as these divorces tend to be more prolonged. Results showed that ‘de Jeugdbeschermingstafel’ does not indicate custody investigation more often for families with complex divorces, than it does in families without complex divorces. Furthermore, this relationship is not moderated by the socioeconomic status of families. However, due to the use of a small sample, this conclusion may be challenging to generalize to the broader population.Show less

Traumatic Brain Injury (TBI) is one of the most common forms of Acquired Brain Injury (ABI), and has a high incidence rate across the world. Following TBI, many patients experience cognitive complaints, as well as physical complaints about their health. Their general wellbeing can also be an issue. Fortunately, for most patients these complaints typically improve over time. This study investigates patients’ memory, concentration, energy, as well as general wellbeing, over time. Methods. Patients received questionnaires about their health and wellbeing every three months following hospital release, with the main goal to track their health and wellbeing after TBI. That data was used for this research. Energy, concentration, and memory were all measured by one question in the questionnaire. General wellbeing was measured by taking the average ratings of all questions on the questionnaire. Analyses were done with three and six questionnaires over time, using repeated measures ANOVAs. Descriptive statistics were used from the first questionnaire. Results. This study found that while patients rated all these measures on average positively, they still did not feel the same as before the injury, and most experienced hindrances in daily life. When looking at the ANOVAs with three questionnaires, there was a significant improvement on concentration, energy, as well as general wellbeing over time. For all of these, most improvement took place between the first and the second questionnaires. Memory did not change significantly over time. None of the ANOVAs with six questionnaires had any significant changes over time. Conclusion. This study shows that patients may suffer from long-lasting effects of TBI. It questions whether more should be done for these patients following hospital release, to alleviate symptoms. This study has limitations concerning selection bias and drop out.Show less

To date, explanations for individual differences in peer evaluation sensitivity have not been thoroughly investigated. The present study examined whether a catastrophizing emotion regulation tendency and overprotective parenting could explain why some adolescents are more sensitive to negative peer evaluation than others. Sixty-four adolescents (mean age = 14.66; 49 females) took part in a Social Evaluative Learning through Feedback (SELF-) Profile task. Participants had to predict the valence of peer feedback in a 240-trial paradigm with four fictitious peers that differed in their probability of giving positive feedback. We hypothesized that through the mediating effect of catastrophizing, parental overprotection could predict the ratio of negative predictions of peer evaluations. We also expected that adolescents scoring higher on these self-reported concepts would have a higher ratio of negative predictions for the most negative vs. the most positive peer. Similarly, it was hypothesized that adolescents with higher catastrophizing and overprotection scores would expect more negative feedback in the SELF-Profile task beforehand and also estimate them to have been high afterward. Our results showed that total parental and paternal overprotection, but not maternal, predicted catastrophizing in adolescents. However, we did not find evidence for the hypothesized mediation models or associations between the self-reported concepts and the SELF-Profile pre- and post-ratings. Together, these findings suggest that parental overprotection and catastrophizing are related concepts but they are not sufficient in explaining negative biases in social reinforcement learning in adolescence.Show less

Tijdens een lesovergang gaat er vaak effectieve onderwijstijd verloren. Dit onderzoek had als doel te onderzoeken in hoeverre effectieve leerkrachtgedragingen voor een lesovergang worden toegepast in de praktijk. Ook zijn er verschillende soorten lesovergangen onderzocht op aanwezigheid van effectieve leerkrachtgedragingen. Om dit te onderzoeken heeft allereerst een literatuurstudie plaatsgevonden om effectieve leerkrachtgedragingen te identificeren. Deze leerkrachtgedragingen zijn verdeeld in twee categorieën namelijk ‘organisatie’ en ‘gedrag’. Vervolgens is er een observatielijst opgesteld. Aan de hand van deze observatielijst hebben er observaties plaatsgevonden op twee verschillende scholen. Er hebben 18 leerkrachten meegedaan aan dit onderzoek. Uit de resultaten blijkt, dat waar leerkrachten al effectieve strategieën gebruiken op het gebied van de organisatie van lesovergangen, ze meer variatie laten zien op het gebied van hun eigen handelen tijdens de lesovergangen. Leerkrachten hebben vaak een overzichtelijke plek in de klas en hebben vaak actieve supervisie. Leerkrachten reageren vaker op ongewenst gedrag dan op gewenst gedrag en leerkrachten zouden vaker gedragsverwachtingen moeten meegeven zodat leerlingen ook gewenst gedrag gaan vertonen. In de discussie wordt ingegaan op de rol van leerkrachtgedrag bij verschillende type lesovergangen.Show less

While many studies have been done on self-stigma, perceived stigma and on the impact of stigmatization on patients with psoriasis, few studies have focused on the extent and predictors of public stigma towards psoriasis. This cross-sectional study is the first study to date to focus on the extent of public stigma towards psoriasis in the Dutch population, as well as to examine the possible predictive value of four subscales of empathy as assessed by the Interpersonal Reactivity Index (IRI); perspective taking, PT; fantasy, FS; empathic concern, EC; and personal distress, PD. Respondents (N = 121) were asked to watch video vignettes, after which public stigma was measured with the Impact of Chronic Skin Disease on Daily Life (ISDL). A paired-samples t-test and multiple regression analysis were conducted. Results suggests that that there is public stigma towards psoriasis in the Dutch population (t(119) = -6.55, p < .001). A weak positive relation between personal distress (PD) and public stigma was found (B = .08, p = .04), while the other three empathy subscales (PT, FS and EC) were not found to be significant predictors for public stigma towards psoriasis (all p-values >.05). These results add to the theoretical knowledge about psoriasis and theory development and suggest that interventions against public stigma towards psoriasis might not focus on eliciting empathy, as other mechanisms would possibly be more beneficial in reducing public stigma. Future studies should replicate the study with other measurement instruments.Show less

To prevent anxiety disorders in young behaviourally inhibited children a parent-focused prevention program called ‘Cool Little Kids’ has been developed. Previous research indicated that both parental engagement and parental anxiety can influence the effectiveness of such programs. Yet, research on the interplay between these factors is limited. Therefore, we investigated the mediating effect of engagement on the relationship between parental anxiety and the effectiveness of ‘Cool Little Kids’. The current study is part of the CLK research project performed by Leiden University. Participants were parents of behaviourally inhibited children between the ages of two and six (N = 42). Parents were interviewed before and after the training about the anxiety of the child, completed a questionnaire about their own anxiety, and were observed during the training to assess parental engagement. Mediation analyses were performed to investigate our hypotheses. No significant meditating effects between parental anxiety, parental engagement and the reduction of the child’s anxiety were found. However, results indicated that parental anxiety had a negative effect on the reduction of the child’s social anxiety. This suggests that CLK should possibly be adapted towards anxious parents of socially anxious children. Furthermore, parental engagement positively influenced the reduction of the child’s separation anxiety. This could be explained by the more central role of parents in separation anxiety but can also suggest that CLK is more suitable for reducing separation anxiety symptoms compared to symptoms of specific phobias and social anxiety and therefore needs adaptation. These results should be handled with care because the current study had several limitations, like a small sample, no control group and many analyses were performed without correction. So, extensive research is necessary to confirm our findings. In conclusion, our findings suggest that in general, parental anxiety and parental engagement do not influence the reduction of the child’s anxiety after CLK. Prevention programs such as CLK are essential to prevent anxiety disorders from occurring and therefore research is needed to improve the effectiveness of these programs.Show less

Een factor die van invloed is op de prestaties van leerlingen is de self-efficacy van de leerkracht. De mate van self-efficacy van een leerkracht hangt samen met het sociaal welbevinden van leerkrachten. In dit onderzoek werd het verband tussen sociaal welbevinden in werkrelaties en de mate van self-efficacy van leerkrachten in burgerschapsonderwijs bestudeerd. Dit werd gedaan door middel van vragenlijstonderzoek onder 59 leerkrachten. Leerkrachten rapporteerden in hoeverre zij zich in staat voelden verschillende burgerschapsonderwerpen te onderwijzen en in hoeverre zij sociaal welbevinden in werkrelaties ervaarden. Uit de analyses van het verband kwamen geen significante resultaten. Daarom kon niet geconcludeerd worden dat er een verband bestaat tussen sociaal welbevinden in werkrelaties en de mate van self-efficacy die leerkrachten ervaren bij burgerschapsonderwijs. Voor de praktijk betekent deze conclusie dat wellicht andere factoren, zoals kennis of motivatie, bekeken moeten worden om de self-efficacy van leerkrachten op het gebied van burgerschapsonderwijs en de burgerschapscompetenties van leerlingen te stimuleren. Meer onderzoek naar factoren die de kwaliteit van burgerschapsonderwijs kunnen bevorderen is nodig.Show less

Als eerst zijn er uit drie reviews van wetenschappelijk onderzoek naar begrijpend leesonderwijs zes elementen gehaald die van belang zijn bij het vormgeven van effectief begrijpend lezen binnen het basisonderwijs. Deze elementen zijn: woordenschat en achtergrondkennis, leesstrategieën, leesmotivatie, technisch lezen, rijke taalomgeving en interactie. Het doel van het onderzoek was om na te gaan hoe deze elementen vormgegeven konden voor PI de Brug. Na het opstellen van de elementen is er onder de werknemers van de school een vragenlijst uitgezet over hoe het begrijpend leesonderwijs binnen de school ervaren wordt. Op basis van de resultaten uit de vragenlijst en wat er bekend is in de literatuur zijn er specifieke adviezen opgezet voor de school. Uit de resultaten bleken woordenschat en achtergrondkennis, leesmotivatie en een rijke taalomgeving als meest belangrijk te worden gezien binnen de school. Technisch lezen en interactie kwamen als laagste uit de resultaten. Deze resultaten en de literatuur hebben geleid tot aanbevelingen voor het begrijpend leesonderwijs op PI de Brug. Aanbevelingen waren bijvoorbeeld om een methode met veel aandacht voor interactie te vermijden, en leesmotivatie en een rijke taalomgeving te stimuleren door veel verschillende tekstsoorten en -structuren aan te bieden.Show less

ACP is generally accepted in Western countries and has a positive effect on end-of-life care for people with dementia. However, culture affects expectations and preferences regarding end-of-life care and decision making. This study compared the acceptability of and preference for two types of ACP interventions for patients with dementia in health care providers from the Netherlands, the US and Japan. One intervention focused on concrete treatment orders in which the patient makes specific decisions. The other focused on what the patient finds important in life, resulting in global goals of care. A total of 125 participants were assessed by means of a structured interview and a questionnaire. Participants found both types of ACP acceptable, in general and per country. A multinomial logistic regression analysis indicated no significant difference in acceptability of the concrete or the global ACP approach between countries when adjusted for age and gender. However, age was a significant predictor of acceptability of the concrete ACP approach (2 (2, 123) = 6.32, p = .042), with older participants being less likely to find it acceptable compared to not finding it acceptable (W(8) = 5.50, p = 0.019). Participants preferred the global ACP approach for patients with dementia. A multinomial logistic regression analysis indicated no significant differences in preference between countries when adjusted for age and gender in general. However, Dutch participants were less likely to prefer the global ACP approach (W(8) = 5.18, p = .023). The relationship between country and preference was not influenced by whether participants most strongly considered what the patient with dementia wants for themselves, what the patient’s family wants or what they as the health care provider want for their patient when making medical decisions. ACP is generally regarded as an acceptable form of care for patients with dementia by health care providers across countries. Future research could more specifically determine which cultural or demographic aspects affect health care providers’ views on different ACP approaches.Show less

However, the exploitation of this shared natural resource poses challenges in terms of sustainability and resource management. This thesis examines the governing framework of the International Seabed Authority (ISA) for the management of deep sea mining in the CCZ. The study draws upon the design principles for governing the commons proposed by Elinor Ostrom to analyze the policies and draft regulations of the ISA. By examining to what extent the policies and regulations of the ISA are aligned with Ostrom's principles, this research aims to evaluate the current governance framework for the management of the CCZ and its resources.Show less

Er werd onderzocht of academische hulpbronnen als buffer kunnen dienen binnen de relatie tussen academische eisen en spanningsklachten. Het onderzoek is gebaseerd op het Study demands-resources model, wat het Jobs demands-resources model toepast in academische context. Bij dit onderzoek werd er gekeken naar verschillende academische eisen: rolconflict, het tempo en de hoeveelheid werk en de mentale belasting. Voor academische hulpbronnen werd er gekeken naar autonomie, rolduidelijkheid en de relatie met de begeleiding. Het onderzoek is uitgevoerd door middel van een online vragenlijst onder universiteit studenten. Het was een cross-sectioneel onderzoek met 171 respondenten. Uit de resultaten is gebleken dat tempo en hoeveelheid werk zorgt voor meer spanningsklachten. Autonomie daarentegen vermindert spanningsklachten. Rolduidelijkheid heeft een buffer-effect op de relatie tussen tempo en hoeveelheid werk en spanningsklachten onder universitaire studenten. Verder is er gevonden dat een hoge score op relatie met de begeleiding een buffer-effect kan hebben op de relatie tussen mentale belasting en spanningsklachten. De uitkomsten van dit onderzoek bieden de mogelijkheid om in te spelen op academische eisen en academische hulpbronnen om vervolgens de spanningsklachten onder studenten te verminderen. Verder kan dit onderzoek een basis zijn voor uitgebreider onderzoek naar spanningsklachten onder studenten en de oorzaken van de spanningsklachten.Show less
