Purpose: Child sexual abuse (CSA) is one of the most serious public health problems among children and adolescents, owing to its widespread prevalence and serious health consequences. The present study aimed to assess the prevalence of, and characteristics and circumstances associated with, CSA. Methods: An epidemiological survey was conducted on a nationally representative sample of 6,787 ninthgrade students (15.5 ± .66 years of age) in Switzerland. Self-reported computer-assisted questionnaires were administered between September 2009 and May 2010. Various forms of sexual victimization were assessed using the newly developed Child Sexual Abuse Questionnaire. Results: Overall, 40.2% and 17.2% of girls and boys, respectively, reported having experienced at least one type of CSA event. Lifetime prevalence rates were 35.1% and 14.9%, respectively, for CSA without physical contact, 14.9% and 4.8% for CSA with physical contact without penetration, and 2.5% and .6% for CSA with penetration among girls and boys. The most frequently experienced event was sexual harassment via the Internet. More than half of female victims and more than 70% of male victims reported having been abused by juvenile perpetrators. Depending on the specific event, only 44.4%-58.4% of female victims and 5.8%-38% of male victims disclosed CSA, mostly to peers. Conclusions: The present study confirms the widespread prevalence of CSA. The high prevalence of CSA via the Internet and the frequent reports of juvenile perpetrators suggest emerging trends in CSA. Low disclosure rates, especially among male victims, and reluctance to disclose events to family members and officials may impede timely intervention.

Lifetime prevalence rates were 35.1% and 14.9% for 'CSA without physical contact'; 14.9% and 4.8% for 'CSA with physical contact without penetration'; and 2.5% and 0.6% for 'CSA with penetration' among girls and boys, respectively.

This paper reports findings on parental engagement in a community-based parent training intervention. As part of a randomized trial, 821 parents were offered group-based Triple P as a parenting skills prevention program. Program implementation was conducted by practitioners. The intervention was implemented between Waves 1 and 2 of a longitudinal study, with a participation rate of 69% and a retention rate of 96%. The study finds that a practitioner-led dissemination can achieve recruitment and completion rates that are similar to those reported in researcher-led trials. Second, the study found that different factors are associated with the various stages of the parental engagement process. Family-related organizational and timing obstacles to participation primarily influence the initial stages of parental involvement. The strength of neighborhood networks plays a considerable role at the participation and completion stages of parental engagement. The general course climate and the intensity of program exposure predict the utilization of the program several months after the delivery.

Background: As people become older, the biological process of aging leads to a decline in functional capabilities, which entails difficulties in the performance of daily tasks. Within the ''Active and Assisted Living Joint Programme'' a consortium from Spain, Germany, and Switzerland developed an interactive Exergame software for older adults to maintain their physical abilities and independence within the daily tasks. Subjects and Methods: An interventional study was conducted to validate the software. For 3 months, Swiss and Spanish seniors used the system at least three times a week for minimum half an hour in their homes. The physical condition in terms of maintaining or increasing strength, balance, safety, and mobility of the seniors was assessed by using the Berg Balance Scale and the Senior Fitness Test. In addition, the effect on independence within the activities of daily living was assessed by using the Canadian Occupational Performance Measure, the Performance Quality Rating Scale, and the Iconographical Falls Efficacy Scale. We used the EQ 5D to evaluate the ''quality of life.'' Results: Twenty-nine participants (male; n = 14; female; n = 15) completed the study. Scores of endurance (2 minutes step test; P = 0.01, g 2 = 0.3) increased significantly. Moderate effect sizes in quality of life (r = 0.3), lower body strength (g 2 = 0.08), and large effect sizes in endurance (g 2 = 0.3) were detected. A small effect was evaluated within the gait speed (r = 0.2), mobility in the lower body (r = 0.2), and the balance capabilities (r = 0.2). Conclusion:The results of this study lead us to the conclusion that physical training with activity-focused exergames that are related to the everyday tasks of older adults could help to maintain and improve the individual fitness status.
