Risky music listening, permanent tinnitus and depression, anxiety, thoughts about suicide and adverse general health.

OBJECTIVE: To estimate the extent to which exposure to music through earphones or headphones with MP3 players or at discotheques and pop/rock concerts exceeded current occupational safety standards for noise exposure, to examine the extent to which temporary and permanent hearing-related symptoms were reported, and to examine whether the experience of permanent symptoms was associated with adverse perceived general and mental health, symptoms of depression, and thoughts about suicide. METHODS: A total of 943 students in Dutch inner-city senior-secondary vocational schools completed questionnaires about their sociodemographics, music listening behaviors and health. Multiple logistic regression analyses were used to examine associations. RESULTS: About 60% exceeded safety standards for occupational noise exposure; about one third as a result of listening to MP3 players. About 10% of the participants experienced permanent hearing-related symptoms. Temporary hearing symptoms that occurred after using an MP3 player or going to a discotheque or pop/rock concert were associated with exposure to high-volume music. However, compared to participants not experiencing permanent hearing-related symptoms, those experiencing permanent symptoms were less often exposed to high volume music. Furthermore, they reported at least two times more often symptoms of depression, thoughts about suicide and adverse self-assessed general and mental health. CONCLUSIONS: Risky music-listening behaviors continue up to at least the age of 25 years. Permanent hearing-related symptoms are associated with people's health and wellbeing. Participants experiencing such symptoms appeared to have changed their behavior to be less risky. In order to induce behavior change before permanent and irreversible hearing-related symptoms occur, preventive measurements concerning hearing health are needed.

Cyber and traditional bullying victimization as a risk factor for mental health problems and suicidal ideation in adolescents.

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 because early-onset mental health problems may pose a risk for the development of psychiatric disorders in adulthood.

Associations between parent-adolescent attachment relationship quality, negative life events and mental health.

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.

Risky music-listening behaviors and associated health-risk behaviors.

OBJECTIVE: To examine, among adolescents and emerging adults attending inner-city lower education, associations between risky music-listening behaviors (from MP3 players and in discotheques and at pop concerts) and more traditional health-risk behaviors: substance use (cigarettes, alcohol, cannabis, and hard drugs) and unsafe sexual intercourse. METHODS: A total of 944 students in Dutch inner-city senior-secondary vocational schools completed questionnaires about their music-listening and traditional health-risk behaviors. Multiple logistic regression analyses were used to examine associations between music-listening and traditional health-risk behaviors. RESULTS: Risky MP3-player listeners used cannabis more often during the past 4 weeks. Students exposed to risky sound levels during discotheque and pop concert attendance used cannabis less often during the past 4 weeks, were more often binge drinkers, and reported inconsistent condom use during sexual intercourse. CONCLUSIONS: The coexistence of risky music-listening behaviors with other health-risk behaviors provides evidence in support of the integration of risky music-listening behaviors within research on and programs aimed at reducing more traditional health-risk behaviors, such as substance abuse and unsafe sexual intercourse.

Confirmatory factor analysis and factorial invariance analysis of the adolescent self-report Strengths and Difficulties Questionnaire: how important are method effects and minor factors?

OBJECTIVES. This study examined the factor structure of the self-report Strengths and Difficulties Questionnaire, paying special attention to the number of factors and to negative effects of reverse-worded items and minor factors within the subscales on model fit. Furthermore, factorial invariance across gender, age, level of education, and ethnicity was investigated. DESIGN. Data were obtained from the Youth Health Monitor Rotterdam, a community-based health surveillance system. METHODS. The sample consisted of 11,881 pupils of 11-16 years old. Next to the original five-factor model, a factor model with the number of factors based on parallel analysis and scree test was investigated. Confirmatory factor analysis for ordered-categorical measures was applied to examine the goodness-of-fit and factorial invariance of the factor models. RESULTS. After allowing reverse-worded items to cross-load on the prosocial behaviour factor and adding error correlations, a good fit to the data was found for the original five-factor model (emotional symptoms, conduct problems, hyperactivity-inattention, peer problems, prosocial behaviour) and a model with four factors (emotional symptoms and peer problems, conduct problems, hyperactivity-inattention, prosocial behaviour). Factorial invariance across gender, age, level of education, and ethnicity was found for the final five- and four-factor model, except for the prosocial factor of the four-factor model that showed partial invariance across gender. Conclusions. While support was found for both models, the final five-factor model is theoretically more plausible and gained additional support as the original scales emotional problems and peer problems showed different relations with gender, educational level, and ethnicity.

Suicidal behavior and ethnicity of young females in Rotterdam, The Netherlands: rates and risk factors.

OBJECTIVE: Although Western Europe is becoming increasingly multicultural, ethnic minorities are scarcely included in studies of suicidology. We investigated the prevalence of non-fatal suicidal behavior and examined risk factors in non-western female immigrant adolescents compared to majority female adolescents in the city of Rotterdam, The Netherlands. DESIGN: We conducted logistic regression on a dataset that consisted of self-reported health and well-being questionnaires filled out by 4527 adolescents of Dutch, South Asian-Surinamese, Moroccan, and Turkish origin. We examined whether young females of specific ethnic groups had elevated risk for attempted suicide. Well-known risk factors in suicidology of social economic class, level of education, life events, abuse, and family context were investigated to verify whether these factors are beneficial to explaining ethnic differences in suicidal behavior. RESULTS; We found that rates of attempted suicide among Turkish and South Asian-Surinamese young women were higher than of Dutch females, while Moroccan females had lower rates than Dutch female adolescents. Physical and sexual abuse, and an impaired family environment, as well as parental psychopathology or parental substance abuse contributed to non-fatal suicidal behavior of females across ethnicities. However, these risk factors, as well as low social economic class and of level of education, did not fully explain the vulnerability of Turkish and South Asian-Surinamese females. CONCLUSION: Our findings underscored the need for developing suicide prevention for specific minority females in multicultural cities in Western Europe. Screening programs, which aim at preventing suicide attempts by young immigrant women should include risk factors in the family environment and relationship with the parents as well as physical and sexual abuse. However, the study also showed that the disproportionate risk of Turkish and South Asian-Surinamese females could not be understood by risk factors alone and transpired that the origins of ethnic disparities in suicidal behavior deserve further examination.

Comparison of web-based versus paper-and-pencil self-administered questionnaire: effects on health indicators in Dutch adolescents.

OBJECTIVE: The aim of this study is to investigate differences in responses related to (mental) health and behavior between two methods of data collection: web-based (web) and paper-and-pencil (p&p). STUDY DESIGN: Within each participating school all third-grade classes (mainly 14-15-year-old pupils) were randomly assigned to either the Internet condition (n=271) or the paper-and-pencil condition (n=261). PRINCIPAL FINDINGS: Significant but small differences were found for the strengths and difficulties subscales "emotional symptoms" (p&p>web) and "prosocial behavior" (p&p>web), and carrying a weapon (web>p&p). Perceived level of privacy and confidentiality did not differ between the two modes. CONCLUSIONS: The findings suggest that in a controlled school setting, web-based administration of health indicators yields almost the same results as paper-and-pencil administration. To generalize these findings, we recommend repeated studies in other populations and settings.

Feeling fat rather than being fat may be associated with psychological well-being in young dutch adolescents.

PURPOSE: To contribute to a further exploration of the association of psychosocial well-being with overweight and weight perception among young Dutch adolescents. METHODS: Data from the ongoing Rotterdam Youth Health Monitor were used from 1,923 9-10-year-olds and 3,841 12-13-year-olds. The association of mental health indicators with weight status based on self-report and measured height and weight was studied with logistic regression analyses in both age groups cross-sectionally. Additional longitudinal analyses were conducted among the 787 pupils for whom follow-up data were available. Interactions with gender and ethnic background were explored. Among the 12-13-year-olds, the role of weight perception was also studied. RESULTS: We found that 9-10-year-old obese boys scored more favourably on social anxiety than nonoverweight boys. Among 12-13-year-olds body weight perception, rather than self-reported or measured weight status was associated with mental health indicators. Mental health indicators at age 9-10 years did not predict self-reported weight status at age 12-13 or change in weight status between 9-10 and 12-13 years, nor did weight status at age 9-10 years predict later mental health indicators or change in these indicators. CONCLUSIONS: This study provides no evidence that overweight does coincide with less favorable psychological well-being in young adolescents. In 12-13-year-old adolescents, feeling overweight, rather than being overweight, appears to be important.

Design and evaluation protocol of "FATaintPHAT", a computer-tailored intervention to prevent excessive weight gain in adolescents.

BACKGROUND: Computer tailoring may be a promising technique for prevention of overweight in adolescents. However, very few well-developed, evidence-based computer-tailored interventions are available for this target group. We developed and evaluated a computer-tailored intervention for adolescents targeting energy balance-related behaviours: i.e. consumption of snacks, sugar-sweetened beverages, fruit, vegetables, and fibre, physical activity, and sedentary behaviours. This paper describes the planned development of a school-based computer-tailored intervention aimed at improving energy balance-related behaviours in order to prevent excessive weight gain in adolescents, and the protocol for evaluating this intervention. METHODS/DESIGN: Intervention development: Informed by the Precaution Adoption Process Model and the Theory of Planned Behaviour, the computer-tailored intervention provided feedback on personal behaviour and suggestions on how to modify it. The intervention (VETisnietVET translated as 'FATaintPHAT') has been developed for use in the first year of secondary school during eight lessons. Evaluation design: The intervention will be evaluated in a cluster-randomised trial including 20 schools with a 4-months and a 2-years follow-up. Outcome measures are BMI, waist circumference, energy balance-related behaviours, and potential determinants of these behaviours. Process measures are appreciation of and satisfaction with the program, exposure to the program's content, and implementation facilitators and barriers measured among students and teachers. DISCUSSION: This project resulted in a theory and evidence-based intervention that can be implemented in a school setting. A large-scale randomised controlled trial with a short and long-term follow-up will provide sound statements about the effectiveness of this computer-tailored intervention in adolescents.
