What Works for Whom in School-Based Anti-bullying Interventions? An Individual Participant Data Meta-analysis.

The prevalence of bullying worldwide is high (UNESCO, 2018). Over the past decades, many anti-bullying interventions have been developed to remediate this problem. However, we lack insight into for whom these interventions work and what individual intervention components drive the total intervention effects.

Does affirming children's autonomy and prosocial intentions help? A microtrial into intervention component effects to improve psychosocial behavior.

Prior research has related children's prosocial behavior to overall well-being, and stimulating prosocial behavior is the aim of many social-emotional skills interventions. This study assessed if affirming children's autonomy stimulates their psychosocial behavior. We conducted a three-arm microtrial with four repeated measures to assess if a social-emotional skills intervention with an autonomy affirmation component had an additive effect on children's behavior as compared to a "regular" intervention focused exclusively on teaching social-emotional skills and a no-treatment control condition.

Effects of Implementing Multiple Components in a School-Wide Antibullying Program: A Randomized Controlled Trial in Elementary Schools.

This study investigates the effectiveness of the PRIMA antibullying program for elementary education using a cluster-randomized trial with two experimental conditions (with and without student lessons) and a control group. Students of 31 schools participated in the study (N = 3,135; M  = 10 years). Multilevel regression analyses demonstrated positive effects of the program on peer-reported victimization and reinforcing behavior.

Effective Components of Social Skills Training Programs for Children and Adolescents in Nonclinical Samples: A Multilevel Meta-analysis.

Social skills training (SST) programs for nonclinical children and adolescents are known to have positive effects on social skills, but it remains unclear how distinct training components are related to program effects. This multilevel meta-analysis examines how psychoeducation (i.e.

[Young people with Down syndrome: independence and social functioning].

Objective: To determine the level of independence and social functioning in young people with Down syndrome.

Design: Cross-sectional study.

Method: Via the Dutch Down Syndrome Foundation (Stichting Downsyndroom), we asked parents of children with Down syndrome born in 1992, 1993 or 1994 to complete a written questionnaire about their child.

Facilitators and barriers to the successful implementation of a protocol to detect child abuse based on parental characteristics.

To determine the critical facilitating and impeding factors underlying successful implementation of a method to detect child abuse based on parental rather than child characteristics known as the Hague Protocol. The original implementation region of the protocol (The Hague) was compared to a new implementation region (Friesland), using analysis of referrals, focus group interviews (n=6) at the Emergency departments (ED) and at the Reporting Centers for Child abuse and Neglect (RCCAN) as well as questionnaires (n=76) at the EDs. Implementation of the Hague Protocol substantially increased the number of referrals to the RCCAN in both regions.

Mainstream and special school attendance among a Dutch cohort of children with Down Syndrome.

Object: To determine the level of mainstream education in a nationwide cohort of adolescents with Down Syndrome (DS), and to find characteristics related to mainstream or special school attendance.

Method: Dutch children with DS born in 1992, 1993 or 1994, were assessed when 16-19 years old. Parents scored school enrolment between the age of 4-18 years, general characteristics and the levels of intellectual disability using the Dutch Social Competence Rating Scale.

Practical and social skills of 16-19-year-olds with Down syndrome: independence still far away.

Survival of children with Down syndrome (DS) has improved considerably, but insight into their level of daily functioning upon entering adulthood is lacking. We collected cross-sectional data from a Dutch nationwide cohort of 322 DS adolescents aged 16-19 (response 62.8%) to assess the degree to which they master various practical and social skills, using the Dutch Social competence rating scale and the Children's Social Behavior Questionnaire.

Problem behavior of individuals with Down syndrome in a nationwide cohort assessed in late adolescence.

Objective: To assess problem behavior in adolescents with Down syndrome and examine the association with sex and severity of intellectual disability.

Study Design: Cross-sectional data of a Dutch nationwide cohort of Down syndrome children aged 16-19 years were collected using a written parental questionnaire. Problem behavior was measured using the Child Behavior Checklist and compared with normative data.

[Reasons for having oneself vaccinated against HPV: implications for the future provision of information].

Objective: To examine which factors determined the participation in HPV vaccination programme in 2009 and 2010.

Design: Retrospective cross-sectional study.

Method: Random samples of Dutch girls who had been invited for the HPV vaccination programme in 2009 and 2010, as well as their mothers, were drawn from an Internet panel.

Determinants of HPV vaccination intentions among Dutch girls and their mothers: a cross-sectional study.

Background: The Dutch government recently added universal Human Papilloma Virus (HPV) vaccination for 12-year-old girls to the existing national immunization program. The participation rate for the initial catch-up campaign for girls aged 13 to 16 years in 2009 was lower (47%) than expected (70%). To inform future HPV information campaigns, this paper examines the social and psychological determinants of the HPV vaccination intentions of girls aged 13 to 16 years and their mothers who were targeted by the Dutch catch-up campaign of 2009.

Significant impact of recurrent respiratory tract infections in children with Down syndrome.

Objective: Parents and health professionals believe that recurrent respiratory tract infections (RRTI) have a large impact on children with Down syndrome (DS). We studied the relation between parent-reported RRTI and development, behaviour and health-related quality of life (HRQoL) in 8-year-old children with DS.

Method: During a 3-year period, 325 children with DS were recruited for inclusion in this observational study.

Development, problem behavior, and quality of life in a population based sample of eight-year-old children with Down syndrome.

Objective: Children with Down syndrome (DS) have delayed psychomotor development. We investigated levels of development, problem behavior, and Health-Related Quality of Life (HRQoL) in a population sample of Dutch eight-year-old children with DS. Developmental outcomes were compared with normative data of eight-year-old children from the general population.

Reliability and validity of the Spanish version of the TAPQOL: a health-related quality of life (HRQOL) instrument for 1- to 5-year-old children.

Objectives: To evaluate the reliability, and construct validity of the Spanish version of the TNO-AZL preschool children quality of life (TAPQOL).

Do bullied children get ill, or do ill children get bullied? A prospective cohort study on the relationship between bullying and health-related symptoms.

Objectives: A number of studies have shown that victimization from bullying behavior is associated with substantial adverse effects on physical and psychological health, but it is unclear which comes first, the victimization or the health-related symptoms. In our present study, we investigated whether victimization precedes psychosomatic and psychosocial symptoms or whether these symptoms precede victimization.

Design: Six-month cohort study with baseline measurements taken in the fall of 1999 and follow-up measurements in the spring of 2000.
