Journal article (peer-reviewed)abstract
- This study examined friendship (de-)selection processes in early adolescence. Pubertal development was examined as a potential moderator. It was expected that pubertal development would be associated with an increased tendency for adolescents to select their friends based on their similarities in externalizing behavior engagement (i.e., delinquency, alcohol use, and tobacco use). Data were used from the first three waves of the SNARE (Social Network Analysis of Risk behaviorin Early adolescence) study (N= 1144; 50 % boys;Mage=12.7; SD= 0.47), including students who entered the first year of secondary school. The hypothesis was tested using Stochastic Actor-Based Modeling in SIENA. While taking the network structure into account, and controlling for peer influence effects, the results supported this hypothesis. Early adolescents with higher pubertal development were as likely as their peers to select friends based on similarity in externalizing behavior and especially likely to remain friends with peers who had a similar level of externalizing behavior, andthus break friendship ties with dissimilar friends in this respect. As early adolescents are actively engaged in reorganizing their social context, adolescents with a higher pubertal development are especially likely to lose friendships with peers who do not engage in externalizing behavior, thus losing an important source of adaptive social control (i.e.,friends who do not engage in externalizing behavior).

The role of self-control and early adolescents’ friendships in the development of externalizing behavior : The SNARE study
- 2016
-
In: Journal of Youth and Adolescence. - : Springer-Verlag New York. - 0047-2891 .- 1573-6601. ; 45:9, s. 1800-1811
-
Journal article (peer-reviewed)abstract
- This social network study investigated themoderating role of self-control in the association betweenfriendship and the development of externalizing behavior: Antisocial behavior, alcohol use, tobacco use. Previous studies have shown inconsistent findings, and did not control for possible friendship network or selection effects. We tested two complementary hypotheses: (1) That early adolescents with low self-control develop externalizing behavior regardless of their friends’ behavior, or (2) as aresult of being influenced by their friends’ externalizing behavior to a greater extent. Hypotheses were investigated using data from the SNARE (Social Network Analysis of Risk behavior in Early adolescence) study (N = 1144,50 % boys, Mage 12.7, SD = 0.47). We controlled for selection effects and the network structure, using a data analysis package called SIENA. The main findings indicate that personal low self-control and friends’ externalizing behaviors both predict early adolescents’ increasing externalizing behaviors, but they do so independently. Therefore, interventions should focus on all early adolescents’with a lower self-control, rather than focus on those adolescents with a lower self-control who also have friendswho engage in externalizing behavior.

Don't Worry! Parental Worries, Alcohol-Specific Parenting and Adolescents' Drinking
- 2013
-
In: Cognitive Therapy and Research. - : Springer Science and Business Media LLC. - 0147-5916 .- 1573-2819. ; 37:5, s. 1079-1088
-
Journal article (peer-reviewed)abstract
- In the present study precursors (risk behavior, parental self-efficacy and parental awareness) of parental worries about their child's behavior during adolescence (12-16 years) were examined. To this end, a new measure of parental worries about the child's involvement in risk behavior is developed. Second, the effect of parental worries on adolescents' alcohol use was tested and third whether ineffective alcohol-specific parenting mediated this effect. Longitudinal data including four waves from 703 parent-adolescent (M age = 12.2 years, SD = 0.5) dyads were used to conduct latent path and growth analysis in Mplus. Results showed that parental awareness, confidence in the effectiveness of their parenting practices and adolescent risk behavior at age 12 related to higher levels of worries in parents. Furthermore, more parental worries predicted an increase in adolescents' drinking (slope), yet worries did not predict the amount of drinking at age 12 (intercept). In addition, parental worries predicted less restrictive rule setting and a lower quality of communication. This ineffective parenting accounted for the effect of parental worries on adolescent alcohol use. In conclusion, this study demonstrated that worries about risk behavior of their child uniquely contribute to higher drinking rates due to less effective parenting. These findings implicate that alcohol interventions should provide parents with effective leads to tackle the drinking behavior in their children (e.g. strict rules about alcohol).

Preventing Heavy Alcohol Use in Adolescents (PAS) : Cluster Randomized Trial of a Parent and Student Intervention offered Separately and Simultaneously
- 2009
-
In: Addiction. - : Wiley-Blackwell. - 0965-2140 .- 1360-0443. ; 104:10, s. 1669-1678
-
Journal article (peer-reviewed)abstract
- Aims: To evaluate the effectiveness of two preventive interventions to reduce heavy drinking in first- and second-year high school students.Design and setting: Cluster randomized controlled trial using four conditions for comparing two active interventions with a control group from 152 classes of 19 high schools in the Netherlands.Participants: A total of 3490 first-year high school students (mean 12.68 years, SD = 0.51) and their parents.Intervention conditions: (i) Parent intervention (modelled on the Swedish Örebro Prevention Program) aimed at encouraging parental rule-setting concerning their children's alcohol consumption; (ii) student intervention consisting of four digital lessons based on the principles of the theory of planned behaviour and social cognitive theory; (iii) interventions 1 and 2 combined; and (iv) the regular curriculum as control condition.Main outcome measures: Incidence of (heavy) weekly alcohol use and frequency of monthly drinking at 10 and 22 months after baseline measurement.Findings: A total of 2937 students were eligible for analyses in this study. At first follow-up, only the combined student–parent intervention showed substantial and statistically significant effects on heavy weekly drinking, weekly drinking and frequency of drinking. At second follow-up these results were replicated, except for the effects of the combined intervention on heavy weekly drinking. These findings were consistent across intention-to-treat and completers-only analyses.Conclusions: Results suggest that adolescents as well as their parents should be targeted in order to delay the onset of drinking, preferably prior to onset of weekly drinking.

Populaire jongeren zetten een norm voor vriendschappen en agressie inde klas
- 2017
-
In: Kind en Adolescent. - : Springer. - 0167-2436 .- 1876-5998. ; 38, s. 212-232
-
Journal article (peer-reviewed)abstract
- In deze studie onderzoeken wij of agressieve peer-normen, meer specifiek populariteitsnormen en descriptieve normen, een versterkende rol spelen in de mate waarin jongeren hun vrienden uitkiezen op basis van agressief gedrag en in de mate waarin jongeren door hun vrienden worden beïnvloed in agressie (N=1.134 eerstejaars leerlingen van middelbare school; leeftijd M=12,66 jaar). Zoals verwacht kwam uit longitudinale sociale-netwerkanalyses met peer-nominatie data naar voren dat vooral populaire jongeren in de klas een norm kunnen zetten voor de ontwikkeling van vriendschappen en agressie. In klassen met agressieve populaire jongeren blijken jongeren hun vrienden te selecteren op basis van gelijkheid in agressie, terwijl dit niet gebeurt in klassen met niet agressieve populaire jongeren. Daarnaast is de vriendschapsinvloed op agressie significant groter in klassen met agressieve populaire jongeren. Descriptieve normen spelen geen rol in vriendschapsprocessen omtrent agressie. Blijkbaar wordt agressie enkel en alleen als een belangrijk, waardevol kenmerk voor vriendschapsprocessen gezien als zij geassocieerd is met populariteit in de klas.

The Role of Prosocial and Aggressive Popularity Norm Combinations in Prosocial and Aggressive Friendship Processes’
- 2020
-
In: Journal of Youth and Adolescence. - : Springer-Verlag New York. - 0047-2891 .- 1573-6601. ; 49:3, s. 645-663
-
Journal article (peer-reviewed)abstract
- Prior work has shown that popular peers can set a powerful norm for the valence and salience of aggression in adolescent classrooms, which enhances aggressive friendship processes (selection, maintenance, influence). It is unknown, however, whether popular peers also set a norm for prosocial behavior that can buffer against aggressive friendship processes and stimulate prosocial friendship processes. This study examined the role of prosocial and aggressive popularity norm combinations in prosocial and aggressive friendship processes. Three waves of peer-nominated data were collected in the first- and second year of secondary school (N = 1816 students; 81 classrooms; Mage = 13.06; 50.5% girl). Longitudinal social network analyses indicate that prosocial popularity norms have most power to affect both prosocial and aggressive friendship processes when aggressive popularity norms are non-present. In prosocial classrooms (low aggressive and high prosocial popularity norms), friendship maintenance based on prosocial behavior is enhanced, whereas aggressive friendship processes are largely mitigated. Instead, when aggressive popularity norms are equally strong as prosocial norms (mixed classrooms) or even stronger than prosocial norms (aggressive classrooms), aggression is more important for friendship processes than prosocial behavior. These findings show that the prosocial behavior of popular peers may only buffer against aggressive friendship processes and stimulate prosocial friendship processes if these popular peers (or other popular peers in the classroom) abstain from aggression.

The Norms of Popular Peers Moderate Friendship Dynamics of Adolescent Aggression
- 2017
-
In: Child Development. - : John Wiley & Sons. - 0009-3920 .- 1467-8624. ; 88:4, s. 1265-1283
-
Journal article (peer-reviewed)abstract
- This study examined whether peer norms for aggression within the classroom impact friendship selection, maintenance, and socialization processes related to aggression across the 1st year of secondary school (N = 1,134 students from 51 classes, Mage = 12.66). As hypothesized, longitudinal social network analyses indicated that friendship selection and influence processes related to aggression depended on the popularity norm within the classroom (i.e., the class-level association between popularity and aggression) rather than the descriptive norm (aggregated average of aggressive behavior). Hence, only in classes where the valence of aggression is high (because it is positively associated with popularity), adolescents tend to select their friends based on similarity in aggression and adopt the aggressive behavior of their friends.

Journal article (peer-reviewed)abstract
- BACKGROUND: This article describes trends and stability over time in health complaints in adolescents from 2002 to 2010 and investigates associations between health complaints, behavioural and social contextual factors at individual level and economic factors at macro-level.METHODS: Comprising N = 510 876 11-, 13- and 15-year-old children and adolescents in Europe, North America and Israel, data came from three survey cycles of the international Health Behaviour in School-aged Children (HBSC) study. Age- and gender-adjusted trends in health complaints were examined in each country by means of linear regression. By using the country as the random effects variable, we tested to what extent individual and contextual variables were associated with health complaints.RESULTS: Significant associations are stronger for individual level determinants (e.g. being bullied, smoking) than for determinants at macro-level (e.g. GDP, Gini), as can be seen by the small effect sizes (less than 5% for different trends). Health complaints are fairly stable over time in most countries, and no clear international trend in health complaints can be observed between 2002 and 2010. The most prominent stable determinants were being female, being bullied, school pressure and smoking.CONCLUSION: Factors associated with health complaints are more related to the proximal environment than to distal macro-level factors. This points towards intensifying targeted interventions, (e.g. for bullying) and also targeting specific risk groups. The comparably small effect size at country-level indicates that country-level factors have an impact on health and should not be ignored.

Journal article (peer-reviewed)abstract
- BACKGROUND: Health complaints are a good indicator of an individual's psychosocial health and well-being. Studies have shown that children and adolescents report health complaints which can cause significant individual burden.METHODS: Using data from the international Health Behaviour in School-aged Children study, this article describes trends in multiple recurrent health complaints (MHC) in 35 countries among N = 237 136 fifteen-year-olds from 1994 to 2010. MHC was defined as the presence of two or more health complaints at least once a week. Logistic regression analysis was performed to evaluate trends across the five survey cycles for each country.RESULTS: Lowest prevalence throughout the period 1994-2010 was 16.9% in 1998 in Austria and highest in 2006 in Israel (54.7%). Overall, six different trend patterns could be identified: No linear or quadratic trend (9 countries), linear decrease (7 countries), linear increase (5 countries), U-shape (4 countries), inverted U-shape (6 countries) and unstable (4 countries).CONCLUSION: Trend analyses are valuable in providing hints about developments in populations as well as for benchmarking and evaluation purposes. The high variation in health complaints between the countries requires further investigation, but may also reflect the subjective nature of health complaints.

Journal article (peer-reviewed)abstract
- BACKGROUND: Previous research provides support for the existence of the psychopathy construct in youths. However, studies regarding the psychometric properties of psychopathy measures with ethnic minority youths are lacking.METHODS: In the present study, the three-factor structure of the Youth Psychopathic Traits Inventory (YPI) was examined for both native Dutch youth (N=158) and an ethnic minority group, Moroccans (N=141), in an incarcerated adolescent population in the Netherlands.RESULTS: Our results showed that the three-factor structure of the YPI is comparable across an ethnic majority and an ethnic minority group in an incarcerated sample in the Netherlands. Moreover, associations between psychopathic traits and mental health problems were similar for both ethnic groups.CONCLUSION: The results support the cross-ethnic generalizability of the three-factor model of psychopathy as measured through the Youth Psychopathic Traits Inventory.
