The goal of the Supportive Parenting Intervention is to prevent and/or decrease parenting stress and provide a sense of empowerment to parents with a newborn child. We evaluated the effectiveness of the Supportive Parenting Intervention in terms of parenting skills, social support, self-sufficiency, resilience, and child psychosocial health. A controlled trial with pre- and post-intervention testing was conducted in the setting of community pediatrics among parents at risk for developing parenting stress. The 177 parents in the control group received care-as-usual, whereas the 124 parents in the intervention group received s

OBJECTIVES: To determine the feasibility, concurrent validity and discriminatory power of the instrument for Identification of Parents At Risk for child Abuse and Neglect (IPARAN) among Dutch parents with a newborn child.SETTING: Community paediatrics.PARTICIPANTS: Data from a contr

Background: School absenteeism, including medical absenteeism, is associated with early school dropout and may result in physical, mental, social and work-related problems in later life. Especially at intermediate vocational education schools, high rates of medical absenteeism are found. In 2012 the Dutch intervention 'Medical Advice for Sick-reported Students' (MASS), previously developed for pre-vocational secondary education, was adjusted for intermediate vocational education schools. The aim of the study outlined in this paper is to evaluate the effectiveness of the MASS intervention at intermediate vocational education schools in terms of reducing students' medical absenteeism and early dropping out of school. Additionally, the extent to which biopsychosocial and other factors moderate the effectiveness of the intervention will be assessed. Methods: A controlled before-and-after study will be conducted within Intermediate Vocational Education schools. Schools are allocated to be an intervention or control school based on whether the schools have implemented the MASS intervention (intervention schools) or not (control schools). Intervention schools apply the MASS intervention consisting of active support for students with medical absenteeism provided by the school including a consultation with the Youth Health Care (YHC) professional if needed. Control schools provide care as usual. Data will be collected by questionnaires among students in both groups meeting the criteria for extensive medical absenteeism (i.e. 'reported sick four times in 12 school weeks or for more than six consecutive school days' at baseline and at 6 months follow-up). Additionally, in the intervention group a questionnaire is completed after each consultation with a YHC professional, by both the student and the YHC professional. Primary outcome measures are duration and cumulative incidence of absenteeism and academic performances. Secondary outcome measures are biopsychosocial outcomes of

Objectives: To assess the prospective associations of physical activity behaviors and screen time with early sexual intercourse initiation (i.e., before 15 years) in a large sample of adolescents. Methods: We used two waves of data from the Rotterdam Youth Monitor, a longitudinal study conducted in the Netherlands. The analysis sample consisted of 2,141 adolescents aged 12 to 14 years (mean age at baseline = 12.2 years, SD = 0.43). Physical activity (e.g., sports outside school), screen time (e.g., computer use), and early sexual intercourse initiation were assessed by means of self-report questionnaires. Logistic regression models were tested to assess the associations of physical activity behaviors and screen time (separately and simultaneously) with early sexual intercourse initiation, controlling for confounders (i.e., socio-demographics and substan

Background Self-esteem and life satisfaction are important aspects of positive mental health in young people, and both are socially distributed. However, the majority of evidence is based on socioeconomic characteristics of the family. As children enter adolescence and gain independence, perceptions of their own social position are likely to influence mental health. Design and objectives Using data on 11-year-olds from the UK Millennium Cohort Study, we investigated associations of both family income and young adolescents' perception of their social position with self-esteem and life satisfaction. We hypothesised that there would be differences in the impact of perceived social position on positive mental health when

__Background:__ In the Netherlands, 15 % of all families with children under the age of 13 years deal with significant parenting problems. Severe parenting problems may lead to adverse physical, cognitive, and psychosocial outcomes for children, both in the short and long run. The intervention Supportive Parenting (in Dutch: "Stevig Ouderschap") is a preventive program, which aims to reduce the risk of (developing) parenting problems among parents at risk of these problems. The intervention consists of six additional home visits by a Youth Health Care nurse during the first 18 months after childbirth and is focusing on the following elements of parental empowerment: activating social networks, increasing parenting skills and supporting parent(s)/caregiver(s) in getting grip on their own life. __Methods and design:__ A controlled trial is performed in two regions in the Netherlands. An intervention group receives the intervention Supportive Parenting, and a control group rece

__Background:__ Self-sufficiency is the realisation of an acceptable level of functioning either by the person him/herself or through the adequate organisation of help from informal or formal care providers. Assessment of self-sufficiency for determining an individual's functional strengths and areas for improvement is increasingly being applied among adolescents in vocational education, a group considered vulnerable with high school dropout rates and often characterised by an accumulation of problems. This study examined the psychometric properties of two instruments, i.e. a self-report questionnaire assessing self-sufficiency and the Self-Sufficiency Matrix for professionals (SSM-D) conducted among adolescents in vocational education. __Methods:__ The self-report questionnaire used to assess self-sufficiency was completed by 581 adolescents. Professionals completed the SSM-D for 224 of the 581 adolescents. Furthermore, constructs related to the domains of self-sufficiency were assessed with self-report questionnaires and information about school absenteeism was monitored via the school registration system. __Results:__ For both self-report and professional-report ratings, the internal consistency was satisfactory (Cronbach'a > 0.70) and various minor to strong correlations were found between the domains of self-sufficiency and related constructs. For most of the domains, there was little or no agreement between professionals and adolescents. __Conclusions:__ Both the self-report questionnaire assessing self-sufficiency and the SSM-D applied in this study seem to possess adequate psychometric properties. The results indicated that adolescents and professionals provide different views of adolescents' self-sufficiency, which merits further study. In the meantime, we recommend assessment of adolescents' self-sufficiency by using both the self-report questionnaire and the SSM-D to get a comprehensive measure of adolescents' self-sufficiency.

__abstract__ A high percentage of adolescents suffer from mental health problems and many health-risk behaviors, such as excessive alcohol consumption, cigarette smoking, and drug (mis)use, are acquired during adolescence. These mental health problems and health-risk behaviors often persist into adulthood, thereby affecting not only current health but also health later in life. Given the adverse short and long term effects of adolescents’ mental health problems and health-risk behaviors, these problems and behaviors are major public health concerns. Insight in factors associated with mental health problems and risk behaviors is needed in order to develop strategies to identify adolescents at risk of these problems and behaviors, and to develop effective interventions to improve adolescents’ health and behaviors. Therefore, the first aim of this thesis was to examine factors associated with mental health problems and health-risk behaviors. The second aim was to evaluate three interventions aiming to identify adolescents’ at risk of mental health problems and health-risk behaviors, and to promote adolescents’ mental health and healthy behaviors. Third, the psychometric properties of the self-report questionnaire assessing self-sufficiency and the Dutch version of the Self-Sufficiency Matrix (SSM-D), both instruments to evaluate adolescent’s levels of self-sufficiency on various domains, were examined among adolescents attending senior vocational education.

BACKGROUND: Depressive symptoms and risk behaviours often do not occur in isolation among adolescents and young adults. In order to improve intervention programmes, more research is needed to elucidate the clustering of risk behaviours, the association with depressive symptoms, and demographic variables. Therefore, this study examined the clustering of risk behaviours, the association with depressive symptoms, and demographic variables among adolescents and young adults in vocational education. Furthermore, the prevalence of depressive symptoms and risk behaviours was examined.METHODS: This study included 584 students (mean age 18.3 years) attending vocational education in the Netherlands. Depressive symptoms and risk behaviours (binge drinking, cannabis use, smoking, delinquency and incurring debts) were assessed with self-report questionnaires. Truancy was monitored via the school registration system. Principal Components Analysis (PCA) was conducted to assess the factor structure of the risk behaviours (i.e. clustering). Linear regression analyses with a bootstrapping method were performed to assess the associations.RESULTS: Binge drinking was reported by 50.5% and cannabis use by 14.2% of the students (both in the past 4 weeks), whereas 37.7% reported currently being a smoker. More than 10% reported having been questioned at a police station in the past year. Furthermore, 82.2% had been truanting in the first two months of education, 21.0% reported having debts and 29.2% reported clinically-relevant depressive symptoms. The PCA indicated two clusters. The 'substance use' cluster consisted of the risk behaviours: binge drinking, cannabis use and smoking. The 'problem behaviours' cluster consisted of the risk behaviours: delinquency, truancy and incurring debts. Both clusters were associated with depressive symptoms. Various demographic variables were associated with both clusters.CONCLUSIONS: Risk behaviours formed two clusters, both of which were associated with

Background: In the Netherlands, 15 % of all families with children under the age of 13 years deal with significant parenting problems. Severe parenting problems may lead to adverse physical, cognitive, and psychosocial outcomes for children, both in the short and long run. The intervention Supportive Parenting (in Dutch: "Stevig Ouderschap") is a preventive program, which aims to reduce the risk of (developing) parenting problems among parents at risk of these problems. The intervention consists of six additional home visits by a Youth Health Care nurse during the first 18 months after childbirth and is focusing on the following elements of parental empowerment: activating social networks, increasing parenting skills and supporting parent(s)/caregiver(s) in getting grip on their own life. Methods and design: A controlled trial is performed in two regions in the Netherlands. An intervention group receives the intervention Supportive Parenting, and a control group receives 'care-as-usual'. Parents in both the intervention and control group fill out three questionnaires focusing on various elements of empowerment (social support, parenting skills, self-sufficiency and resilience), behavioral and emotional problems of the child. The effects of the intervention will be evaluated at child age 1-3 months (baseline) and child age 18 months by comparing the outcomes between the intervention group and the control group on the primary outcomes. Additionally, interviews and focus group interviews will be held to identify factors, which hinder or stimulate a wider implementation of the intervention Supportive Parenting. Discussion: It is hypothesized that parents at increased risk of parenting problems who receive the intervention Supportive Parenting during the first 18 months after childbirth, will have enhanced their social support networks and parenting skills, increased their self-sufficiency and strengthened resilience compared to at risk parents receiving careas- usual

Background: To promote well-being and health behaviors among adolescents, 2 interventions were implemented at 12 secondary schools. Adolescents in the E-health4Uth group received Web-based tailored messages focused on their health behaviors and well-being. Adolescents in the E-health4Uth and consultation group received the same tailored messages, but were subsequently referred to a school nurse for a consultation if they were at risk of mental health problems. Objective: This study evaluated the effect of E-health4Uth and E-health4Uth and consultation on well-being (ie, mental health status and health-related quality of life) and health behaviors (ie, alcohol and drug use, smoking, safe sex). Methods: A cluster randomized controlled trial was conducted among third- and fourth-year secondary school students (mean age 15.9, SD 0.69). School classes (clusters) were randomly assigned to (1) E-health4Uth group, (2) E-health4Uth and consultation group, or (3) control group (ie, care as usual). Adolescents completed a questionnaire at baseline and at 4-month follow-up assessing alcohol consumption, smoking, drug use, condom use, mental health via the Strengths and Difficulties Questionnaire (SDQ) and the Youth Self Report (YSR; only measured at follow-up), and health-related quality of life. Multilevel logistic, ordinal, and linear regression analyses were used to reveal differences in health behavior and well-being between the intervention groups and the control group at follow-up. Subsequently, it was explored whether demographics moderated the effects. Results: Data from 1256 adolescents were analyzed. Compared to the control intervention, the E-health4Uth intervention, as a standalone intervention, showed minor positive results in health-related quality of life (B=2.79, 95% CI 0.72-4.87) and condom use during intercourse among adolescents of Dutch ethnicity (OR 3.59, 95% CI 1.71-7.55) not replicated in the E-health4Uth and consultation group. The E-health4Uth and consu

Background: Health promotion for adolescents is important in the prevention of mental health problems and health-risk behaviors. We implemented two interventions in a preventive youth health care setting. Adolescents in the E-health4Uth group received Web-based, tailored messages on their health behavior and well-being. Adolescents in the E-health4Uth and counseling group received the same tailored messages, but were subsequently referred to a school nurse for a consultation if they were at risk of mental health problems. Objective: This study evaluated the use and appreciation of these Web-based, tailored messages and additional consultation with a school nurse. Differences in use and appreciation according to demographics (ie, gender, level of education, and ethnicity) of the adolescents were also assessed. Methods: Two youth health care organizations participated in this study and conducted the interventions in 12 secondary schools. In total, 1702 adolescents participated; 533 in the E-health4Uth group, 554 in the E-health4Uth and counseling group, and 615 in the control group (ie, care as usual). Adolescents completed an evaluation questionnaire assessing the use and appreciation of the tailored messages immediately after receiving these messages and at a 4-month follow-up. After the consultation, adolescents and nurses completed an evaluation questionnaire on the use and appreciation of the consultation. Results: The majority of the adolescents (845/1034, 81.72%) indicated they had read the tailored messages. Most items on the use and appreciation of the tailored messages and the program were scored positive (overall satisfaction on a scale from 1, most-negative, to 10, most-positive: mean 6.70, SD 1.60). In general, adolescents in vocational training, girls, and adolescents of non-Dutch ethnicity, indicated they used the tailored messages more often and appreciated the content of the messages better than adolescents receiving preuniversity education, boys, and

Purpose: To examine whether traditional and cyber bullying victimization were associated with adolescent's mental health problems and suicidal ideation at two-year follow-up. Gender differences were explored to determine whether bullying affects boys and girls differently. Methods: A two-year longitudinal study was conducted among first-year secondary school students (N = 3181). Traditional and cyber bullying victimization were assessed at baseline, whereas mental health status and suicidal ideation were assessed at baseline and follow-up by means of self-report questionnaires. Logistic regression analyses were conducted to assess associations between these variables while controlling for baseline problems. Additionally, we tested whether gender differences in mental health and suicidal ideation were present for the two types of bullying. Results: There was a significant interaction between gender and traditional bullying victimization and between gender and cyber bullying victimization on mental health problems. Among boys, traditional and cyber bullying victimization were not related to mental health problems after controlling for baseline mental health. Among girls, both traditional and cyber bullying victimization were associated with mental health problems after controlling for baseline mental health. No significant interaction between gender and traditional or cyber bullying victimization on suicidal ideation was found. Traditional bullying victimization was associated with suicidal ideation, whereas cyber bullying victimization was not associated with suicidal ideation after controlling for baseline suicidal ideation. Conclusions: Traditional bullying victimization is associated with an increased risk of suicidal ideation, whereas traditional, as well as cyber bullying victimization is associated with an increased risk of mental health problems among girls. These findings stress the importance of programs aimed at reducing bullying behavior, especially becaus

Purpose: The aim of this study was to examine the association of negative life events and parent-adolescent attachment relationship quality with mental health problems and to explore an interaction between the parent-adolescent attachment relationship and one or multiple negative life events on the mental health of adolescents. Methods: A two-year longitudinal study was conducted among first-year secondary school students (N = 3181). The occurrence of life events and the quality of parent-adolescent attachment were assessed at baseline and mental health status at two-year follow-up by means of self-report questionnaires. Binary logistic regression analyses were conducted to assess associations between life events, parent-adolescent attachment and mental health problems. Relative Excess Risk due to Interaction techniques were used to determine the interaction effects on the additive scale. Results: Life events were related to mental health status, as was parent-adolescent attachment. The combined effect of an unfavourable parent-adolescent attachment with life events on mental health was larger than the sum of the two individual effects. Among adolescents with one life event or multiple life events, an unfavourable parent-adolescent attachment increased the risk of mental health problems at follow-up compared to the group without life events. Conclusion: Results supported an interaction effect between parent-adolescent attachment and negative life events on mental health. Especially adolescents with one or multiple life events and an unfavourable parent-adolescent attachment seems to be a vulnerable group for mental health problems. Implications for further research are discussed.

Background: About 15% of adolescents in the Netherlands have mental health problems and many also have health risk behaviours such as excessive alcohol consumption, cigarette smoking, use of drugs, and having unsafe sex. Mental health problems and health risk behaviours may have adverse effects on the short and longer term. Therefore, in the Netherlands there is a considerable support for an additional public health examination at age 15-16 years. The study evaluates the effect of two options for such an additional examination. Adolescents in the 'E-health4Uth' group receive internet-based tailored health messages on their health behaviour and well-being. Adolescents in the 'E-health4Uth + counselling' group receive the computer-tailored messages combined with personal counselling for adolescents at risk of mental health problems. Methods and design. A three-arm cluster randomised controlled trial will be conducted in the Netherlands among fourth-grade secondary school students. School classes are the unit of randomisation. Both intervention groups complete the computer-tailored program during one class session; the program focuses on nine topics related on health behaviour and well-being. For each topic a score is computed that can be compared with the Dutch health norms for adolescents. Based on the score, a message is presented that reflects the person's current behaviour or well-being, the Dutch health norm, and offers advise to change unhealthy behaviour or to talk to a person they trust. Adolescents in the 'E-health4Uth + counselling' group are also invited for an appointment to see the nurse when they are at risk of mental health problems. The control group receives 'care as usual'. The primary outcome measures are health behaviour (alcohol, drugs, smoking, safe sex) and mental health status. The secondary outcome measure is health-related quality of life. Data will be collected with a questionnaire at baseline and at 4-months follow-up. A process evaluation

Objective: One of the most unfavourable trends in the eating habits of secondary school students in the Netherlands, that contributes to weight gain, is the decrease in fruit and vegetable consumption. Before the effect of self-efficacy on fruit and vegetable consumption can be examined, reliable and valid instruments have to be developed. The purpose of this research was to develop and test a ‘fruit self-efficacy’ (FSE-)instrument and a ‘vegetable self-efficacy’ (GSE-)instrument for secondary school students in the Netherlands. The research question was: What is the reliability and validity of the FSE-instrument and GSE-instrument? Design: Research aimed at developing and testing instruments can be characterized as methodological research. Setting/Subjects: Secondary school students (11-19-years-old) in the Netherlands completed the two developed instruments during class hours (n=466). Fewer students participated in the second round (n=106). Results: First, the relevance of the twenty-two items of the two developed instruments was evaluated on two occasions by four experts. This procedure resulted in seventeen items for both instruments. Further analysis was based on the responses of the students. Factor analysis identified two unidimensional instruments. Cronbach's alpha for the FSE-instrument was 0.94 and for the GSE-instrument 0.95. The intra-class correlation coefficient between test and re-test of both instruments ranged between 0.33 and 0.84 (P<0.05), depending on the method of completing the instruments (in the classroom or on one’s own initiative) and the order of completing the instruments (started or ended with another instrument in the context of a similar study). The correlation between FSE and fruit consumption was 0.41 (P<0.01), and for GSE and vegetable consumption it was 0.32 (P<0.01). Conclusion: The two self-efficacy instruments are sufficiently reliable and valid to asses the FSE and GSE in secondary school students in the Netherlands. Additional
