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

Although digital tools can address the growing gap between healthcare supply and demand, their implementation is difficult, and personal factors can influence individuals’ intention to use such tools. Thus, this study explores the relationship between various personal factors, as self-reported by healthy individuals (N = 507) who are part of a brain research registry, and their intention to use and promote using digital tools in the context of brain health and dementia. According to the hypothesis formulated for the research, higher financial scarcity, lower educational attainment, and lower employment status predict lower intention to use and promote digital tools for brain health. The study examined four distinct digital tools: (1) MijnBreincoach (a prevention tool), (2) cCog (a diagnostic tool), (3) ADappt (a patient- orchestrated care tool), and Neurokeys (a prediction tool). It was found that Neurokeys exhibited the highest score for intention to use but the lowest score for intention to promote. In addition, medium and high educational attainment predicted higher behavioral intention to use MijnBreincoach, while the most beneficial (i.e., most secure, stable, and safe) employment status predicted higher intention to promote MijnBreincoach and cCog. In conclusion, it is important to recognize differences in intention to use and promote different types of digital tools across potential users and the influence of personal characteristics on the intention to use and promote digital tools for brain health. During the development of a digital tool, it is recommended to consider which target audience would derive the greatest benefit from it and tailor it accordingly.Show less

Participants were 127 adolescents aged between 10 and 14 years old who reported on their empathy, prosocial behavior, and self-perception of close friendships in three consecutive years, respectively. Simple mediation analyses revealed that cognitive and affective empathy did not have a significant positive effect on adolescents’ self-perception of close friendships two years later. Considering these findings, prosocial behavior was not found to be a mediator between adolescents’ cognitive or affective empathy and their self-perception of close friendships from late childhood to early adolescence. Moreover, cognitive and affective empathy did not significantly predict prosocial behavior one year later, whereas prosocial behavior did significantly predict the self-perception of adolescents’ close friendships one year later. These results underline the significance of developing tailored intervention programs targeting prosocial behavior to foster adolescents’ self-perception as close friends, a competence that is crucial during this developmental period considering the greater influence of peers.Show less

Op dat moment vindt er een terugval plaats, ook wel een setback genoemd. Na het ervaren van een setback wordt het moeilijker een gedragsdoel vol te houden. Deze studie onderzoekt waarom dit moeilijk wordt door de relatie tussen de ervaren setbacks tijdens het volgen van een dieet en maintenance self-efficacy te analyseren, met subjectief succes als mogelijke mediator. Met een online vragenlijst (N= 74) zijn de ervaren setbacks, maintenance self-efficacy en subjectief succes uitgevraagd. De vragenlijst had een cross-sectioneel, between-subjects design. De antwoorden op de vragenlijst zijn geanalyseerd met lineaire regressieanalyses en met een mediatie analyse. De resultaten lieten een significante negatieve relatie zien tussen de ervaren setbacks en maintenance self-efficacy. De relatie tussen de ervaren setbacks en subjectief succes was significant negatief, maar de relatie tussen subjectief succes en maintenance self-efficacy was niet significant. Echter, de resultaten lieten zien dat de ervaren setbacks weldegelijk negatief gerelateerd waren aan maintenance self-efficacy, en dat subjectief succes een negatieve mediërende rol in deze relatie kan hebben. Samengevat, de resultaten suggereren dat de ervaren setbacks kunnen zorgen voor een afname in maintenance self-efficacy en subjectief succes, wat weer zou kunnen leiden tot een toename in het ervaren van setbacks. Deze resultaten hebben gezorgd voor nieuwe inzichten, maar meer onderzoek is nodig naar andere mediërende factoren zoals recovery self-efficacy om het setback effect beter te kunnen begrijpen.Show less

To address this effectively, it’s important to understand to what extend factors such as academic stress, parental expectations and family well-being influence the development of anxiety and mood disorders. Relatively little is known about the anxiety and worry experienced by early adolescent children and the extent to which this is culture dependent. The present study sought insight in the worries of children aged 10-12 years from Western and non-Western cultural backgrounds. In addition, the extent to which internalizing symptoms are related to achievement anxiety, parental expectations and family well-being was examined. This was done by interviewing 74 Indian children (M = 10.92 ; SD = 0.75) and 69 Dutch (M = 11.17 ; SD = 0.92) children using the Cultural Formulation Interview. In addition, the amount of internalizing complaints and family welfare were determined using RCADS and FASIII. Results showed that children from India more often experienced achievement-oriented anxiety than Dutch children, and that this was associated with a greater amount of internalizing symptoms. The parental expectations that Indian children experienced were often achievement-oriented expectations regarding school or future profession, whereas the parental expectations of Dutch children were more often focused on being able to show responsibility for tasks. This might be explained by the values transmitted from parent to child within individualistic and collectivistic culture. Evidence exists that cultural values remain present when families from collectivist cultures move to a country with a more individualistic culture. It is therefore extremely important to be aware of these cross-cultural differences within mental health care, as well as education, when dealing with adolescents with anxiety and mood problems.Show less

It is hypothesized that exercise of moderate and high intensity enhance creativity more effectively than exercise of lower intensity. The study also investigates if arousal, positive high-arousal affect, and negative high-arousal affect serve as intermediary variables in this relationship. Scarce previous research has suggested a relationship between exercise-intensity and creativity, but studies comparing different exercise-intensities on creativity and potential underlying mechanisms were lacking. To address this knowledge gap, this study compares different intensities, namely low-intensity (cycling at 55% of maximum heart rate), moderate-intensity (cycling at 70% of maximum heart rate), high-intensity (cycling at 85% of maximum heart rate) and a control group, on divergent creativity (i.e., number and uniqueness of creative ideas); And looks at affect and arousal as underlying mechanisms. Happy (positive), elated (positive), upset (negative), tense (negative) and stressed (negative) are used as indicators for high-arousal affect and feelings of wakefulness and alertness as indicators for arousal. Participants in this study completed two appointments, of which the first appointment consisted of a fitness test to measure participants’ maximum heart rate. During the second appointment, participants were randomly assigned to one of the four conditions and their affect and arousal were measured before and after the exercise or control task. Creativity was measured after the exercise or control task was completed. A Kruskal-Wallis Test showed that participants in the moderate-intensity and high-intensity exercise did not show higher creativity. Further, macro PROCESS model 4 revealed a significant effect of moderate-intensity and high-intensity exercise on arousal in comparison to low-intensity exercise and a significant effect of moderate-intensity exercise on positive high-arousal affect, in comparison to the control group. Other than this, the model revealed that none of the mediators significantly explained a relationship between exercise-intensity and creativity. This study thus suggests that exercise-intensity does not play a significant role in creativity enhancement, nor does arousal or high-arousal affect. However, future research is needed to confirm this for other modes of exercise, regular exercise instead of acute bouts of exercise and for different individual characteristics, such as age and gender.Show less

While TMS appears promising for stroke rehabilitation, there is variability in the level of improvement individuals exhibit. This variability may be attributed to oscillatory neurophysiology, which refers to the rhythmic electrical activity of the brain. Therefore, this study investigated phase-dependent changes in cortical excitability after TMS among stroke patients in affected and unaffected hemispheres. We investigated motor-evoked and TMS-evoked potentials at four phases of the ongoing motor cortical mu rhythm (trough, peak, rising, falling) in both hemispheres (affected, unaffected). Participants comprised N=11 chronic subcortical stroke patients (6 female, mean ± std age: 58 y ± 11.4) with affected lateralized upper-limb impairment. Four blocks of 150 TMS pulses were applied on each hemisphere, targeting the primary motor hotspot of the first dorsal interosseus muscle of the contralateral hand. Participants watched nature videos during stimulation to maintain consistent attention levels. Cortical excitability was assessed by analyzing motor-evoked potentials (MEP) and TMS-evoked potentials (TEP). Results showed that motor responses (measured through MEP amplitudes) were significantly larger at the trough and rising phase compared to the peak phase. No significant differences were observed between the affected and unaffected hemispheres. TEP components, the brain signals in response to TMS, did not exhibit significant phase-dependent changes. While our findings showed a nonsignificant effect of stroke severity, exploratory correlation analyses presented a positive association between higher remaining movement function and enhanced phase-dependent responses to TMS. The findings build upon previous research indicating phase-dependent changes in cortical excitability for MEPs but not for TEPs. The larger MEP amplitudes during trough and rising phases suggest that TMS can be more effective at specific points of cortical activity. Further exploration is needed to assess the efficacy of phase-specific TMS interventions in clinical settings, potentially through larger-scale clinical trials with longitudinal designs and comparative effectiveness studies, aiming to evaluate functional outcomes and determine their impact on motor recovery.Show less

Het huidige onderzoek bekijkt het effect van seksuele oriëntatie, gender en geslacht op de prestatie op een navigatietaak. Het onderzoek verspreidde een online vragenlijst met navigatietaak onder 216 deelnemers met een gemiddelde leeftijd van 27 jaar oud. 65 van de deelnemers waren van het mannelijke geslacht en 151 van het vrouwelijke geslacht. Hiervan waren 151 deelnemers heteroseksueel en 65 niet-heteroseksueel. Uit de resultaten van het onderzoek bleek dat seksuele oriëntatie, gender en geslacht geen effect hebben op de prestatie van mensen op een navigatietaak. Dit kan komen door de kleine individuele groepen binnen de niet-heteroseksuelen, waardoor er geen goede conclusie over de aparte groepen getrokken kan worden. Toekomstige onderzoeken zouden meer LHBTQIA+ organisaties kunnen betrekken bij het werven van deelnemers.Show less
