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

While sustainable diets are widely acknowledged for their ecological benefits, the interplay of social-emotional factors shaping such choices remained relatively underexplored. This study explored the interplay between guilt proneness, emotional support from best friends, and open- mindedness and their influence on young adults’ pro-environmental dietary choices. These variables were selected for their distinct impacts on decision-making processes and behavioural intentions, as guilt proneness motivates alignment with moral values, emotional support provides social reinforcement and validation, and open-mindedness encourages adoption of atypical diets. Plant-based diets involve (mostly) excluding meat including variations like flexitarian and pescetarian diets, while vegetarian diets exclude meat, and vegan diets exclude meat and animal-derived foods and products. The dietary choices in this study rank from the least to the most sustainable diet, being omnivores, plant-based, vegetarian, and ultimately, vegan. The cross-sectional design incorporated 213 individuals aged 17 to 26 from multiple genders and nationalities. The multiple stages assessment included a 45-minute online survey that employed specific tests to assess the factors. Dietary choice was assessed using the Dietarian Identity Questionnaire, guilt proneness using the Test of Self-Conscious Affect–3, emotional support from best friends using the Official short version of the Network Relationship Inventory, and open-mindedness using the Big Five Inventory-2. The multiple regression analyses indicated that guilt proneness, emotional support from best friend, open-mindedness, and the three-way interaction of these variables were non-significant predictors of dietary choice. These results diverged from initial hypotheses, emphasizing the need for exploration within different contexts and populations. The study's strengths included its cross-sectional design encompassing multiple nationalities and genders, and the thorough validation of statistical assumptions. However, the questionable to low reliability of some measures and the unequal gender distribution possibly affected the generalizability of the findings. Additional factors that may influence dietary choices among young adults, including cultural norms, socioeconomic status, anticipated pride, and peer influence, should be incorporated in future research. Interventions aimed at promoting pro- environmental dietary choices among young adults must adopt a holistic approach, considering individual, social, and environmental factors to facilitate long-term behaviour change.Show less

It is important that they get support to get financially back on track. However, they often refrain from seeking help, likely due to the shame associated with their financial situation (Keizer, 2016; Plantinga, 2019). This shame hinders their ability to adopt problem-focused coping strategies and consequently improve their financial circumstances (De Hooge et al., 2010). However, shame resilience shows a promising role in addressing this issue. It involves reducing feelings of entrapment, powerlessness, and isolation, thereby managing feelings of shame in a way so that enables people to effectively deal with their situation (Brown, 2006). This study investigates the effectiveness of shame resilience interventions in increasing communication between creditors and debtors. We conducted an experiment involving participants in debt and manipulated creditor letters to increase shame resilience. Results indicate that shame resilience interventions significantly increase willingness to contact creditors and improve the perceived trustworthiness of the company. These findings suggest that applying shame resilience interventions can assist people in taking the first step toward seeking help to address their debt.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

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
