Show moreIntroduction: Physical and verbal violence toward staff or other detained individuals is a reoccurring problem within correctional facilities. Screening for violence risk within the prison setting could provide a valuable first step in the prevention of institutional violence. The brief and compact Risk Screener Violence (RS-V) has shown to be an efficient new method for assessing concerns regarding post-release violent offending for incarcerated persons. This study aimed to find out whether the RS-V is also able to predict future violent and aggressive incidents during imprisonment.Methods: The predictive validity of the RS-V for future violent and aggressive incidents during a follow-up time of 4 months within prison was analyzed, using a file-based design. Violent incidents toward staff and other inmates (physical violence and violent threats), other aggressive incidents (aggression toward objects and verbal disruptive behavior), and both categories combined, were included as outcome measures based on disciplinary reports.Results: The RS-V showed medium to large predictive values for both violent and aggressive behavior during prison stay. In particular, good predictive values of the RS-V were found for violence toward prison staff.Discussion: This study shows that, besides post-release violent recidivism, the RS-V is able to accurately predict future violent and aggressive incidents during prison stay. By correctly differentiating between low concern and high concern individuals, the RS-V aims to contribute to more personalized interventions and risk management and, subsequently, to improved prison safety. Future studies using prospective prison practice data are needed to further support the validity of the RS-V regarding institutional violence. Show less

Show moreParental socialization refers to the process through which parents transmit values and beliefs to their children. During this process, children learn to understand the world and shape their social functioning. The impact of parental socialization can vary across different cultures. My research focuses on family interactions within Chinese cultures, emphasizing the importance of cultural nuances when examining the role of parental behaviors in children's social development. The study utilized samples of Chinese children and their parents, employing various research methods, including observations, interviews, and questionnaires. The findings indicated that Chinese mothers' psychological control had a relatively minor negative effect on children's emotion regulation and social anxiety. Additionally, the research revealed racism and colorism among Chinese children, which were associated with mothers' color-evasive socialization behaviors. Chinese mothers did not avoid talking about racial appearance and cultural background, which contrasts with studies in White Western populations where most White mothers showed color evasion. Chinese mothers’ acknowledgement of shared culture predicted children’s positive attitudes towards their own racial ingroup with a darker skin tone. My research underscores the unique features of Chinese culture that play a pivotal role in shaping the nature and consequences of parental socialization on children's social functioning. It highlights that Western theories related to parenting and color-evasive socialization may need adaptation when applied to non-Western cultural contexts. Show less

Show moreIt is estimated that up to 25% of all children growing up worldwide experience child maltreatment, making it a global emergency with substantial individual and public health consequences. This chapter addresses one of the most societally pervasive consequences of child maltreatment which is known as the "cycle of victimization." This concept depicts the increased risk of maltreated individuals to victimize others later in life, both within and outside the family environment. To understand the architecture of this victimization cycle, the chapter further sheds light on neurocognitive mechanisms aiding different forms of victimization and the buffering role of social support that could help break the cycle of victimization. Advancing our understanding of these complex and interrelated mechanisms will ultimately facilitate the design and implementation of more targeted early treatments and (preventive) interventions and support a move toward a safer society.

Show moreDe huidige studie had als doel om te onderzoeken of 1) de schoolinterventie Rots en Water (r&w) effectief was in het verbeteren van competenties en voorkomen van problemen in het intra- en interpersoonlijkdomein van leerlingen op het voorbereidend middelbaar beroepsonderwijs (vmbo), en of 2) interventie-effecten veranderden naarmate er meer mensen betrokken waren bij de interventie (kernteam van leerkrachten, het hele schoolteam, het hele schoolteam en ouders). We hebben een gerandomiseerdegecontroleerde studie uitgevoerd onder brugklassers (N = 1299; Mleeftijd = 12,38; 54 % jongens) die vier keer digitale vragenlijsten hebben ingevuld. De resultaten lieten zien dat r&w een aantal interventie-specifieke uitkomsten (zelfcontrole en emotionele zelfregulatie), uitkomsten in het intrapersoonlijk domein(psychologisch welzijn, seksuele autonomie en internaliserend gedrag) en in het interpersoonlijk domein (agressie) verbeterde, maar uitsluitend wanneer een kernteam van leerkrachten betrokken was bij de implementatie van de interventie. De (gematigde) interventie-effecten waren het grootste in het eerste jaar van de tweejarige interventie. Deze resultaten laten zien dat r&w positieve effecten kan bewerkstelligen bij vmbo-leerlingen wanneer deze geïmplementeerd wordt door een kernteam. Het lijkt dus waardevol voorscholen om te investeren in interventies met een leerstijl die aansluit bij die van de doelgroep, met een hoge kwaliteit van implementatie en een beperkt aantal betrokken personen.

Show moreBackground Engagement with smartphone‑based interventions stimulates adherence and improves the likelihood of gaining benefits from intervention content. Research often relies on system usage data to capture engagement. However, to what extent usage data reflect engagement is still an open empirical question. We studied how usage data relate to engagement, and how both relate to intervention outcomes. Methods We drew data from a randomized controlled trial (RCT) (N = 86) evaluating a smartphone‑based intervention that aims to stimulate future self‑identification (i.e., future self vividness, valence, relatedness). General app engagement and feature‑specific engagement were retrospectively measured. Usage data (i.e., duration, number of logins, number of days used, exposure to intervention content) were unobtrusively registered. Results Engagement and usage data were not correlated. Multiple linear regression analyses revealed that general app engagement predicted future self vividness (p = .042) and relatedness (p = .004). Furthermore, engagement with several specific features also predicted aspects of future self‑identification (p = .005 – .032). For usage data, the number of logins predicted future self vividness (p = .042) and exposure to intervention content predicted future self valence (p = .002). Conclusions Usage data did not reflect engagement and the latter was the better predictor of intervention outcomes. Thus, the relation between usage data and engagement is likely to be intervention‑specific and the unqualified use of the former as an indicator of the latter may result in measurement error. We provide recommendations on how to capture engagement and app use in more valid ways. Show less

Show moreWe developed and tested a smartphone-based intervention, FutureU, that aims to stimulate future-oriented thinking and behavior by strengthening the degree to which people identify with their future self. In order to examine the potential of this intervention prototype and opportunities for further optimization, we evaluated 1) the immediate and long-term efficacy of the intervention, and 2) intervention effects after each of three intervention modules. To this end, we conducted a randomized controlled pilot study among first-year university students (N = 176). Results showed a decrease in goal commitment immediately after the intervention. At 3-months follow-up, trends showed an increase in future orientation and in self-efficacy. During the intervention, there was a positive effect on vividness of the future self after the first module. Although there is scope for improvement, the findings highlight the potential of the intervention to increase people’s future-oriented thinking and behavior. Show less

Show moreThe current study explored individual and gendered differences in Black students’ motivation for learning mathematics using three key Situated Expectancy-Value Theory (SEVT) constructs (expectancies of success, interest, and importance). It also evaluated whether math motivational profiles in 6th grade or 10th grade predicted math achievement and STEM career aspirations in 10th grade among Black students while controlling for prior math achievement. Black students (n = 408, 55% female) attending schools in a metropolitan area of Tennessee, USA and mostly from families surviving economic marginalization completed surveys and math achievement assessments across middle and high school. Latent Profile Analysis identified three profiles of math motivation in 6th grade, including a profile of high motivation across constructs, and Black girls were less likely to be in the high motivational profile than Black boys. Profile membership in 6th grade predicted 10th grade math achievement. In contrast, math motivation profiles in 6th grade did not predict STEM career aspirations in 10th grade. Parallel analyses for concurrent relations in 10th grade were similar, except that there were no gender differences in profile prevalence. Overall, findings suggest that SEVT is useful for understanding motivation and academic performance among Black students when a person-centered analytic approach is used, but more work is needed to expand the theory to understand the development of Black students’ STEM career aspirations.

Show moreBelonging is a basic human need, with social isolation signaling a threat to biological fitness. Sensitivity to ostracism varies across individuals and the lifespan, peaking in adolescence. Government-imposed restrictions upon social interactions during COVID-19 may therefore be particularly detrimental to young people and those most sensitive to ostracism. Participants (N = 2367; 89.95% female, 11-100 years) from three countries with differing levels of government restrictions (Australia, UK, and USA) were surveyed thrice at three-month intervals (May 2020 - April 2021). Young people, and those living under the tightest government restrictions, reported the worst mental health, with these inequalities in mental health remaining constant throughout the study period. Further dissection of these results revealed that young people high on social rejection sensitivity reported the most mental health problems at the final assessment. These findings help account for the greater impact of enforced social isolation on young people's mental health, and open novel avenues for intervention. Show less

Show moreAbout 1 in 650-1000 children are born with a 47,XXY, 47,XXX or 47,XYY chromosomal pattern (i.e, sex chromosome trisomies, SCT). The presence of SCT is associated with an increased risk for neurodevelopmental difficulties across the life-span. Studying neurodevelopment in early childhood in children with SCT could signal deviations in development that serve as risk markers to guide clinical care. This thesis explored the development of self-regulation (emotion, cognition, and behavior) in SCT children and population-based controls, aged 1 to 7 years, who participated in the TRIXY Early Childhood Study. Behavioral symptoms were assessed through structured behavioral observation and parental questionnaires. Neurocognition was measured using performance tests and psychophysiological measures of arousal. Outcomes showed behavioral symptoms of psychopathology and neurocognitive vulnerabilities, already from an early age. Difficulties in self-regulation tended to become more pronounced with increasing age and were rather robust; independent of karyotype, pre/postnatal diagnosis, or intelligence-levels. A developmental neurocognitive perspective is key in increasing our knowledge of gene-brain-behavior pathways in SCT as well as advancing clinical care (diagnostics and treatment). Self-regulation amongst other neurocognitive functions may serve as a valuable target for early, tailor-made interventions to minimize the risk for psychopathology later in life and improving quality of life.

Show moreTeaching can be emotionally demanding. The current study investigated how teachers handle demanding situations in class, and how their behavioral and physiological reactions shape their emotions after the lesson. Interpersonal behaviors of 80 secondary school teachers were coded based on video recordings of one real-life lesson. During the lesson, heart rate and cardiac output were recorded continuously as indicator of relative challenge versus threat motivational states. Overall, teachers differed substantially in the number of demanding situations and how they changed their interpersonal behavior and physiological responses. Although teachers’ behavioral and physiological changes were not a straightforward predictor of their emotional outcomes, especially teachers with dispositional low agency or communion were at risk of less positive and more negative emotions.

Show moreDifferentiated instruction concerns adapting education to students’ needs. However, relatively little is known about how students experience the degree to which their teachers fulfill their individual educational needs. In the current study, the Differentiated Instruction from Students’ Perspective (DISP) questionnaire was developed and administered among 458 students of grade 4 to 6 of 22 primary school teachers in the Netherlands. The internal consistency of the DISP instrument was considered good. Students in general were moderately positive about the level of differentiation they experienced and few differences between DISP-ratings of students with varying mathematics achievement levels were identified. It is concluded that the DISP questionnaire is a suitable instrument to study students’ perspectives and can be used by researchers as well as by teachers who would like to gain insights in and improve their differentiation practice.
