Het beïnvloedt beslissingen, gedragingen en het draagt ook bij aan de ontwikkeling en het in stand houden van welbevinden. Echter kan te veel of ambigue informatie ook ongewenste effecten teweegbrengen, zoals verhoogde angst en stress. Het is daarom van belang dat zowel het verwerven als het verstrekken van informatie zo adaptief mogelijk genavigeerd kan worden. Vooral voor een populatie die al te maken heeft met verhoogde aanwezigheid van stressoren en angst zoals mensen met een laag sociaaleconomische status. Door middel van een online vragenlijst waarbij informatie-zoekend gedrag, sociaaleconomische status en angst onderzocht werden, bleek de sociaaleconomische status geen effect te hebben op informatie-zoekend gedrag, en was er ook geen significante moderatie van angst. De resultaten suggereren dat de sociaaleconomische status en het persoonlijkheidskenmerk angst geen invloed hebben op informatie-zoekend gedrag. Mogelijke verklaringen kunnen onder andere zijn dat het construct van sociaaleconomische status niet uitputtend is gemeten. En dat angst de relatie alleen modereert wanneer grote veranderingen plaatsvinden en niet met meer geleidelijke veranderingen, wat in lijn is met eerder onderzoek. Dit onderzoek draagt bij aan de inzichtelijkheid van de verschillende dimensies die onderdeel zijn van sociaaleconomische status, informatie-zoekend gedrag en angst.Show less

Digital storybooks can lead to a child being read to more often since they don’t rely on an available adult to read aloud. This study investigated whether the teacher’s attitudes toward printed and digital storybooks correlated with their class's frequency of logging into Bereslim, an interactive digital storybook platform for children aged 3 to 7 years old. The study also examined whether the number of children in a class at risk of developing language problems correlates with the frequency of logins to Bereslim. Additionally, it investigated whether teacher’s attitude toward printed storybooks could predict the amount of Bereslim logins. Lastly, the study explored whether the teacher's age impacted their attitude toward reading digital storybooks and the frequency of logins. In this research 8 teachers from 6 schools and 1 daycare participated, completing an online questionnaire about their attitudes toward reading aloud with print and digital storybooks. Log data was also utilized, containing information about the frequency of logins into Bereslim in each class. No significant results were found regarding teachers' attitudes toward print and digital storybooks and the frequency of logging into Bereslim in their class. There was no significant correlation between the number of children in the class who are at-risk of developing a language problem and the teachers' attitude toward print storybooks. Neither teachers' age nor their attitudes toward digital storybooks significantly predicted login frequency. It's possible that the sample was too small to produce significant effects. To increase the usage of Bereslim in class, providing teachers with more information about the platform and opportunities to gain experience with digital storybooks could be beneficial. A lack of experience with digital storybooks prevents teachers from using them.Show less

The study investigated: (1) if there is an AB to or from itch; (2) whether this differs between people with chronic itch and healthy controls; (3) and if there is a possible AB/stress association. This is because understanding ABs to/from itch further elucidates the experience of patients with chronic itch and possible future clinical applications. Furthermore, an explorative analysis compared two tasks measuring AB, namely the Posner cueing and dot-probe task. The two tasks, alongside a stress-questionnaire, were administered online to the participants (N=70). A (frequentist and Bayesian) RM ANOVA was done for the main analysis, and a within- subjects t-test for the explorative task-comparison. Given that the task-comparison found the two tasks differing significantly (p = 0.01 d = -0.31), the results of the two tasks were interpreted separately. Overall, indications of AB being biased away from itch stimuli was found. When the AB was contrasted between participant group (people with and without chronic itch), the Posner cueing task found no significant difference (p = 0.68, ηp 2 = 0.003) whereas the dot-probe task found an AB away from itch-stimuli in patients with chronic itch (p = 0.02, ηp 2 = 0.077). Similar pattern unfolded with the stress-association: the Posner cueing task finding that AB did not significantly differ with stress (p = 0.23, ηp 2 = 0.021). The dot-probe task did find that they significantly differed (p = 0.01, ηp 2 = 0.091) where with higher stress, the AB switched to being an AB towards itch stimuli. The discrepancy between the two tasks aligns with expectations considering that the tasks were found inequivalent - highlighting one of the strengths of this study being that the two tasks were compared. Altogether this points towards differences in what the two tasks tap into, and that the attention of people with chronic itch is biased as a function of stress. Summarizing, AB to itch differed between the two groups and was associated with stress when using dot-probe task, which did not apply to the Posner cueing task.Show less

Individuals with a history of childhood maltreatment may have impairments in extinction learning processes, potentially affecting the efficacy of these therapies for this population. Investigation of this relationship between childhood trauma and extinction learning can better the development of effective therapeutic strategies for those with trauma histories.. The relationship between childhood maltreatment and extinction learning in healthy volunteers was investigated to explore whether individuals with a history of childhood maltreatment exhibit different patterns of threat extinction compared to those without exposure to maltreatment. Using a cross-sectional design, data was analyzed from healthy adult volunteers, combined from two studies (n= 73), those with and without exposure to childhood maltreatment, divided into two groups based on their Childhood Trauma Questionnaire (CTQ-SF) scores. Participants completed an extinction paradigm, during which skin conductance responses (SCR) and heart rate (HR) were measured. The results showed that CTQ-exposed participants exhibited heightened HR to CS+ and lower responses to CS- during extinction trials compared to non-exposed individuals, revealing distinct physiological reactions. There were no additional significant differences in SCR and HR extinction and re-extinction patterns between the maltreatment-exposed and non-exposed groups. These findings suggest that childhood maltreatment may not necessarily impair extinction learning in a healthy adult population. Further research with longitudinal designs and clinical populations is needed to further understand how maltreatment experiences may influence extinction processes.Show less

Data were collected using a scenario approach (N = 205) in an experimental study, which simulated a debt assistance setting in a municipality. The variables Status (low/high) and Warmth (low/high) were investigated in a betweensubjects design. Participants completed an online survey on perceived warmth, status, and locus of attribution of a help-seeker and indicated their willingness to help as well as the type of help. It was hypothesized that warmth perceptions of help-seekers would influence the likeliness to help, that status perceptions would influence the locus of attributions as well as the type of help and that the effect between status and type of help would be mediated by the locus of attributions. The study did not find support for these hypotheses. However, exploratory analyses revealed a significant positive effect of both Status and Warmth on perceived competence, and significant correlations between locus of attributions and likeliness to help, autonomy and dependency-oriented help, and emotions (admiration/envy/pity) and type of help. These findings underline the role of stereotypes and biases in influencing helping behavior, emphasizing the need for further investigations of helping mechanisms.Show less

This study focused on the role of friendships in feelings of loneliness in autistic students and their allistic peers. We aimed to examine the extent to which autistic and allistic students differ in the number of perceived, received, and reciprocal friendships, how these three types of friendships are related to feelings of loneliness in school, and how autistic and allistic (without ASD) students differ in this relation. Forty-one autistic students (92,7% male, M age = 10.17, SD = 1.0) were compared with 44 allistic students (43,2% male, M age = 11.14, SD = 1.0), both from special education schools. Participants completed the Children’s Loneliness Scale and provided names of their best friends (up to five names). Results indicated that autistic students did not have fewer perceived, received, and reciprocated friendships than their allistic peers, and did not differ in feelings of loneliness with their allistic peers. Also, the number of received and reciprocal friendships did not contribute to feelings of loneliness, but having more perceived friendships was associated with less feelings of loneliness, to the same extent in the two groups. In conclusion, the findings showed that autistic students can form friendships that fulfill their social needs when in a suitable environment, and the perception of having friends could be the most important for both groups to feel a sense of connectedness in school. Thus, for regular schools, it may be helpful to learn from special education schools to facilitate the best environment for all students to form and maintain friendships.Show less

Three-quarters of chronically depressed people have experienced childhood trauma. Depression, described as a disorder of impaired emotion regulation, is linked to various disordered eating behaviors. Emotional eating, overeating in response to negative affect, is viewed as a maladaptive emotion regulation strategy and may contribute to the creation, maintenance, or worsening of depressive symptoms. This study aimed to examine the association between childhood trauma and emotional eating in a large sample of adults with current or past depression. Given that women show higher prevalence in disordered eating, we tested for a moderation effect of gender. Additionally, we explored how separate subtypes of trauma are related to emotional eating. We used data from the Netherlands Study of Depression and Anxiety (NESDA), an ongoing naturalistic longitudinal cohort study. The sample consisted of 1,353 individuals (818 women, 355 men) aged 26-75 years (M = 51.30). To assess childhood trauma, depression, and emotional eating, we used the Comprehensive Trauma Interview, CIDI 2.1, and the Dutch Eating Behaviour Questionnaire. As hypothesized, childhood trauma was predictive of emotional eating. Although women showed higher levels of emotional eating, no moderation effect of gender was found. As the first study in the Netherlands to examine these relationships, the results highlight the importance of assessing childhood trauma in any psychopathology and emphasize the need to screen for emotional eating in the depressed population to better inform treatment options.Show less

In examining this relationship, researchers address what is referred to as the therapeutic alliance. Contemporary research established this alliance as an important common factor that has a significant effect on therapeutic outcomes. An alliance rupture is defined as a breakdown in agreement on therapeutic goals or tasks or of the therapeutic bond. Such ruptures are a near inevitable aspect of the therapeutic process. Distinct from existing meta-analyses which explored the relationship of rupture repairs on outcomes, the present research examines the effect that alliance ruptures themselves, identified through direct measures, have on therapeutic outcomes. Five studies were included in the meta-analysis (N = 366). A multilevel model was used to determine an aggregate effect size of ruptures on outcome across the included studies. In agreement with the paper’s hypothesis, the analysis showed a small but consistent positive relationship between ruptures and therapeutic outcomes where increased ruptures correlated with greater impairment in outcomes.Show less

Hashimoto’s thyroiditis patients may experience cognitive impairments such as memory problems, even after receiving LT4-monotherapy. This study investigates the memory performance of Hashimoto’s thyroiditis patients with residual symptoms after receiving LT4 monotherapy, utilizing participants from the T3-4 Hypo Trial. Memory performance was assessed using the Rey Auditory Verbal Learning Test (RAVLT) 15-Word Task and the data were compared to normative data from the Advanced Neuropsychological Diagnostics Infrastructure Norms (ANDI-Norms). Results indicate that Hashimoto’s thyroiditis patients do not significantly perform different to the general population. This study investigated whether age and sex are potential predictors of memory performance. These factors showed no significant results suggesting that they are not related to memory performance. However, this study does highlight limitations such as possible comorbidity, uneven distribution of sex and education levels that need consideration. Future research is advised to better understand the complex relationship between Hashimoto’s thyroiditis and cognitive function. This study contributes to the broader understanding of the relationship between cognitive function and Hashimoto’s thyroiditis and underscores the need for future research to develop effective and/or improve existing clinical management strategies.Show less

Many people with autism spectrum disorder have difficulty regulating their emotions and often participate in harmful and suicidal behaviors to cope with these emotions. To date, there is not a form of therapy that fully addresses these problems in people with autism spectrum disorder. Dialectical behavior therapy does address this difficulty with emotion regulation and suicidal behavior, but is not yet implemented as an official intervention for people with autism spectrum disorder. In this study, nine participants received 42 weeks of inpatient dialectical behavior therapy. All participants have a history of suicidal thoughts and/or attempts and suffer from comorbid disorders, such as attention deficit hyperactivity disorder, post-traumatic stress disorder and depression. Assessments were done at baseline, start of pretreatment, start of inpatient treatment, end of inpatient treatment and at follow-up. The primary measured outcome was problem behavior, which was measured with daily diary cards. Primary problem behavior consisted of suicidal urges; secondary problem behavior consisted of self-harm, substance abuse or rumination. The secondary measured outcomes were coping styles, emotion regulation and quality of life, and these were measured with multiple questionnaires. At follow-up, four out of nine participants saw a significant reduction in suicidal urges (p < .001). Seven participants saw a significant reduction in secondary problem behavior (p < .001). The secondary measured outcomes were more variable with some significant improvement seen in coping styles, emotion-regulation and quality of life, but not for all participants (RCI > 1.96/RCI > -1.96). One participant dropped out after the end of inpatient treatment. In short, this study has found that dialectical behavioral therapy has potential as an effective treatment for people with autism spectrum disorder and emotion-regulation problems, but more studies are needed to fully substantiate this claim before it can be implemented as standard treatment.Show less

Through convenience sampling, participants’ demographic data, EMS score (YSQ-3), ACE score (ACE questionnaire), and presence of transdiagnostic somatic symptoms (DSM-5 Self-Rated Level 1 Cross-Cutting Symptom Measure) were measured. The total scores of subjugation and self-sacrifice, ACE, and transdiagnostic somatic symptoms were respectively summated, then analysed through mediation analysis. Participants were (N = 131) students of Leiden University from the age of 18 years old (M = 19, IQR = 2), comprising of 91.2% female and 8.8% male. Through the analysis, it was found that subjugation and self-sacrifice together significantly mediate the relationship between ACE and transdiagnostic somatic symptoms (b = .314, p = .003). The indirect effect was found to have mediated 55.6% (b = .175, p = .002) of the relationship. Moreover, exploratory analyses indicated that individually, subjugation and self-sacrifice also successfully mediated this relationship. This finding further strengthens the existing argument that following ACE, particular behavioral stress-response may lead to transdiagnostic somatic symptoms in later life. In this case, the schemas subjugation and self-sacrifice were found to be crucial in this relationship. Thus, providing a deeper look into the developmental trajectory of the ACE, EMS, and transdiagnostic domains and may aid clinicians in recognizing and targeting schemas related to transdiagnostic somatic symptoms.Show less

Uit eerder wetenschappelijk onderzoek komt naar voren dat een goede dosis zelfvertrouwen een positieve invloed heeft op het voorkomen van mentale problematiek. Maar welke sporten helpen daar exact bij? En hoe vaak dient men dan te sporten? Deze studie gaat in op deze vragen en focust daarbij op de sporten crossfit en tradionele krachttraining (TK). Om de hoeveelheid en soorten sport te meten is gebruik gemaakt van een demografische vragenlijst in combinatie met de Muscle-Strengthening Exercise Questionnaire (MESQ). Om het zelfvertrouwen van de respondent te meten is de Rosenberg Self-Esteem Scale (RSES) gebruikt. Dit onderzoek vindt geen significant verschil in het niveau van het zelfvertrouwen tussen jongvolwassenen die niet sporten, die aan TK doen en die aan crossfit doen. Dit kan als reden hebben dat crossfit en TK hetzelfde effect op het zelfvertrouwen hebben. Daarnaast vielen alle overige sporters in dit onderzoek onder niet-sporters wat niet representatief is voor de jongvolwassenen die niet sporten. Wel kan gesteld worden dat het gezond is voor de lichamelijke en geestelijke gezondheid om te bewegen en het zelfvertrouwen te vergoten. Gezien de geringe hoeveelheid crossfitters die deelnamen aan dit onderzoek kan geen constructief antwoord komen op de vraag welke sport meer effect heeft op het zelfvertrouwen. Vervolgonderzoek kan zich richten op een uitgebreider model van het zelfvertrouwen.Show less
