While genetic factors are important, the environment, particularly parental influence, also plays a significant role in the development of childhood overweight, as children of overweight parents are more often overweight. Parents pass on their genetic predispositions but also their learned eating behaviors to their children. This thesis explores how three different parental feeding styles moderate the intergenerational transmission of BMI between mothers and children: Restriction, Pressure to Eat, and Responsiveness to Child Fullness Cues. Participants were recruited through the Baby's First Bites project and were visited repeatedly at home. This study included 205 mother-child dyads, and children were assessed aged 36 months. Responsiveness to Child Fullness Cues and Pressure to Eat were assessed through observations, while Restriction was measured using the Infant Feeding Style Questionnaire. Both mothers and children were weighed at home and their BMIs were calculated using their height and age. The moderation analysis revealed a significant relationship between maternal and child BMI. Pressure to Eat acted as a negative moderator, with high levels of Pressure to Eat weakening the BMI relation between mothers and children. When analyzing the effect of gender, the full model was not significant for boys. However, for girls, Pressure to Eat remained a significant negative moderator, with high levels of Pressure to Eat weakening the BMI relation between mothers and children . These findings suggest that maternal BMI is a significant predictor of BMI in 36-month-old girls but not in boys, and that maternal Pressure to Eat moderates this relation. Intervention programs should consider these gender differences. However, due to the cross-sectional nature of this study, causal relationships cannot be inferred.Show less

Preventative measures are crucial in reducing these disorders' incidence and negative outcomes. However, preliminary research on the mechanisms behind anxiety prevention programs is limited. This longitudinal study aimed to investigate a program designed to prevent anxiety development by targeting parents of behaviorally inhibited children, as they are at risk for anxiety. The research question was: What is the moderating effect of the gender of the child and the age of the parent in the mediating relationship of parental anxiety on the effectiveness of the Cool Little Kids (CLK) intervention on child anxiety post-intervention, compared to pre-intervention? A total of 76 parents and their inhibited children aged three to six years were included in this study. The study employed a randomized controlled trial (RCT) design to assign them to either the CLK parenting training or a book with general parenting tips. Child anxiety was measured using a condensed version of the Diagnostic Infant and Preschool Assessment (DIPA) interview administered to the parent, and parental anxiety was assessed using the State-Trate Anxiety Inventory (STAI) questionnaire. A moderated mediation analysis was conducted for separation anxiety, specific phobias, and social anxiety using the PROCESS plug-in for SPSS. The findings indicated that none of the moderated mediation models nor the individual pathways were significant. All hypotheses were rejected. No significant difference in child anxiety was found pre- to post-intervention in both the CLK intervention and active control condition, and parental anxiety does not mediate this relationship. Child gender and parental age did not significantly moderate the link between child and parental anxiety. Despite excelling in among others its preventive system-oriented approach and credibility, this study has several limitations that warrant further research to firmly conclude the role of parental anxiety in CLK’s effectiveness on child anxiety. Recommendations include employing a larger and more diverse sample and experimenting with different scoring methods for the DIPA interview.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

Research shows mixed results regarding executive functioning (EF) deficiencies in adolescent Anorexia Nervosa (AN), contrasting with established EF impairments in adult AN patients. This study aimed to assess EF and its association with Body Mass Index (BMI) in adolescent girls with first-onset AN. Method. 79 AN patients were compared to 75 matched healthy controls (HC), all females aged 12-22. EF was assessed using the Central Coherence Index (CCI) of the Rey Complex Figure Test (RCFT) and the Behavior Rating Inventory of Executive Functioning (BRIEF). Standardized BMI scores (BMI-SDS) were used to determine the influence of BMI on EF. Measurements were taken at baseline (T1) and one-year follow-up (T2). Results. Total EF scores showed no differences between AN and HC at baseline or follow-up. Compared to HC, AN patients had significantly worse scores on the BRIEF subscales Flexibility (p < .001; p < .001), Emotion Regulation (p < .001; p = .006), and Initiative (p < .001; p = .006), and significantly better scores on Orderliness and Neatness (p = .002; p < .001). P-values represent T1 and T2 respectively. At baseline, AN patients scored significantly higher on the RCFT CCI (p = .009). There was no significant relation between BMI-SDS and EF. Conclusions. Compared to HC, AN patients had normal EF scores with mild weaknesses in set- shifting, emotion regulation, and initiating skills, and strengths in orderliness and neatness. Changes in EF were unaffected by BMI-SDS. This study enhances understanding of EF in adolescent AN patients, which can aid the development of treatment programs.Show less

Therefore, it is crucial to investigate the factors influencing these decisions. Previous research indicates that these decisions are not always made correctly and exhibit substantial variability. This study utilizes the Decision Making Ecology Model to analyse the influence of risk assessment tools and work experience on these decisions. Data were collected through a questionnaire and a case file study. The analyses show that the use of risk assessment tools has a significant impact on the decisions made. Work experience did not have a significant direct influence, but the use of risk assessment tools indirectly affected work experience, which in turn had a small effect on the final decisions.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

Rejection sensitivity is an aspect of social anxiety disorder which is especially prevalent in adolescents. SAD has a significant relationship with social feedback learning rate and this study aims to go a step further and research whether rejection sensitivity is a leading factor in this relationship. Participants fill in the Liebowitz Social Anxiety Scale as well as the Children’s Rejection Sensitivity Questionnaire. Afterwards they will do a speech task which includes a public speaking section and is judged by confederate judges who will rate them on their performance. The participants rate themselves before and after the feedback from the judges. The difference between individual’s rating before and after the feedback will be measured and this will form the basis of our data for analysis. During the analysis a correlational relationship will be analyzed between rejection sensitivity, its sub measures and social feedback learning rate. The hypothesis of the study is that individuals with higher rejection sensitivity score will have higher negative social feedback learning rates. Results show no significant relationship between the variables.Show less

The relationships between social anxiety, audience perception, and expressiveness are considered to play a role in the development of those problems, since they cause intense distress or even avoidance of social or performance situations. Effective treatment options are therefore important to prevent further problems. This study examined the relationship between social anxiety, audience perception, and expressiveness, and the feasibility of blended care. To examine this, 43 participants followed a 12 week blended care intervention consisting of psychoeducation, social skills training, cognitive restructuring techniques, exposure tasks, assertiveness training, and homework assignments. In addition, the Social Anxiety Scale for Adolescents, the Audience Perception Questionnaire, and the Speech Performance Observation Scale for Youth were administered before and after treatment. A mediation analysis was done to study whether audience perception mediated the relationship between social anxiety and expressiveness. To test whether blended care was feasible in reducing symptoms of social anxiety, and increase audience perception and expressiveness, multiple paired samples t-tests were performed. No significant relationships were found between social anxiety and audience perception (β = -.054, p = .40), between social anxiety and expressiveness (β = .005, p =.37), and between audience perception and expressiveness (β = -.009, p =.75). Logically, the whole mediation model was also not significant (β = .005, p =.45). Results from the paired samples t-tests showed significant differences for social anxiety (t(29) = 2.66, p = .013), lowering the mean scores from 56.8 to 50.6, and audience perception (t(28) = -4.00, p < .001), increasing the mean scores from -3.2 to -0,8. No significant differences were found for expressiveness (t(13) = .10, p = .92). The results show no relationships between social anxiety, audience perception, and expressiveness, which could be explained by the unfamiliarity of the concept of expressiveness, a different mediator that has influence on these variables, having a small sample size, or participants’ level of education. Further research is needed on both, to gain more insight in relationships affecting social anxiety in adolescents. The results did show the feasibility of blended care in reducing social anxiety and increasing audience perception. Using blended care is encouraged to provide more and better care to adolescents.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

Empathic concern is associated with pro-social behaviours, whereas personal distress is linked to avoidant behaviours. However little research has been done in a parental sample. This study explores whether empathic concern might mediate the relationship between parental anxiety and parental bonding. Parental bonding is the expected behavioural outcome of empathy and encompasses supportive parenting behaviours. Using data from the RE-PAIR study, a mediation analysis via regression was conducted. The sample consisted of 143 parents and their (adolescent) child. The parental bonding was measured through a questionnaire that the child had to fill in about their parents after the reminiscence task (REM). The REM was conducted in the lab, the task entailed that the child had to talk about an emotional event. Results showed that there was no mediating effect, though anxiety did seem to correlate significantly with empathic concern (β = 0.20, p = 0.01). There was no correlation found between anxiety and parental bonding or between empathic concern and parental bonding. This suggests that higher empathic concern does not necessarily translate into perceived supportive parenting behaviours. This may indicate issues in the communication of expressing empathy. Perhaps, family therapies or a training focusing on emotional communication could be beneficial. Future research could focus on conducting multiple lab measures in order to take out more situational variables.Show less

The study used a 2x2 factorial design with 41 three-person groups (N = 123), who engaged in a structured negotiation task. Hypothesis 1 predicted that prosocial groups would achieve higher joint outcomes than pro-self groups, and results of an ANOVA supported this prediction. Hypotheses 2 and 3, predicting that structured communication, using headphones to manipulate turn-taking behaviour, would improve prosocial and reduce pro-self groups negotiation outcomes, respectively, were not supported by an ANOVA. This suggests that while prosocial motives significantly improve outcomes, structured communication alone does not. Future research should explore additional communication structuring methods and broader contexts to validate these findings.Show less

Confirmatory factor analysis found that a unidimensional structure of the SIAS, in which its three reverse- coded items were removed (S-SIAS), showed the best fit for both samples. Subsequently, this model was used in a hierarchical multi-group confirmatory factor analysis (MGCFA). The results of the MGCFA support the S-SIAS’ configural and metric invariance across these two countries. This is an indication of the S-SIAS being a unidimensional measure of social interaction anxiety in the USA and China. However, the results indicate the presence of only partial scalar invariance. Therefore, it is likely that individuals from these cultures interpret certain items of the SIAS differently, which complicates direct comparisons across these groups. What this implies for past and current research comparing individuals from these cultures, in terms of social anxiety, as well as implications for future research, are explored further.Show less

Sibling relationships are crucial, as they offer daily opportunities for children to develop social skills. The quality of sibling relationships can be influenced by various factors, including adverse childhood experiences (ACEs), which include 10 types of possible traumatic experiences among which child abuse, neglect and household dysfunction. ACEs can negatively impact a child's social and emotional development, posing risks to their ability to form and maintain relationships and having a possibly negative effect on their mental health later on in life. Current research often only considers biological siblings while the step-sibling relationship was the fastest-growing type of sibling relationship in families with divorced parents between 1997 and 2017. Therefore, the current study aimed to investigate the association between ACEs and the quality of the relationship among both biological and step-siblings who have experienced parental divorce. Hundred young adults between the ages of 18 and 25 completed a questionnaire in which they answered questions about their relationship with their siblings and their ACEs. Multiple regression analyses revealed that ACEs were similarly associated with a lower quality of the sibling relationships for both biological and stepsiblings. Specifically, emotional abuse by a parent during childhood and having a parent with alcohol and/or drug problems during childhood were linked to lower quality of the sibling relationship, while other childhood experiences examined were not related to relationship quality. These results highlight the significance of improving sibling relationship quality, as these relationships may buffer the adverse impacts of traumatic experiences. Adopting a family-focused approach could reduce these negative impacts, addressing the shadow of the past that these experiences may cast on sibling relationships.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

Daarnaast gaan mensen, ongeacht hun SES, meer op zoek naar positieve informatie dan naar negatieve informatie. In hoeverre SES minder informatiezoekend gedrag vertoont voor specifieke informatie is onduidelijk. In dit paper werd onderzocht of de SES variabelen inkomen en opleiding invloed hebben op informatiezoekend gedrag én of dit afhankelijk is van de valentie van de informatie, positief of negatief. Om deze hoofdeffecten en het interactie effect van SES en valentie te onderzoeken hebben de participanten (N = 130) een informatie zoektaak uitgevoerd, waarin de valentie (positief, negatief) van informatie werd gemanipuleerd en een vragenlijsten ingevuld over inkomen en opleiding. De resultaten toonden een hoofdeffect van valentie aan, waarbij participanten een hogere motivatie hadden voor positieve informatie in vergelijking met negatieve informatie. De hoofdeffecten van SES waren niet significant. De interactie tussen valentie en SES inkomen, en valentie en SES opleiding waren ook niet significant. Hieruit kan geconcludeerd worden dat de valentie van informatie invloed heeft op het informatiezoekend gedrag van mensen, maar dat SES geen invloed heeft op het informatiezoekend gedrag van mensen. Echter is er in dit onderzoek niet naar een breed scala aan SES variabelen gekeken, alleen naar inkomen en opleiding. In dit onderzoek is er alleen gekeken naar informatiezoekend gedrag in een financiële context, terwijl veel van het huidige bewijs in de medische context is gevonden.Show less
