Music interventions are used for stress reduction in a variety of settings because of the positive effects of music listening on both physiological arousal (e.g., heart rate, blood pressure, and hormonal levels) and psychological stress experiences (e.g., restlessness, anxiety, and nervousness). To summarize the growing body of empirical research, two multilevel meta-analyses of 104 RCTs, containing 327 effect sizes and 9,617 participants, were performed to assess the strength of the effects of music interventions on both physiological and psychological stress-related outcomes, and to test the potential moderators of the intervention effects. Results showed that music interventions had an overall significant effect on stress reduction in both physiological (d = .380) and psychological (d = .545) outcomes. Further, moderator analyses showed that the type of outcome assessment moderated the effects of music interventions on stress-related outcomes. Larger effects were found on heart rate (d = .456), compared to blood pressure (d = .343) and hormone levels (d = .349). Implications for stress-reducing music interventions are discussed.
The Short-Term Assessment of Risk and Treatability: Adolescent Version (START:AV) is a risk assessment instrument for adolescents that estimates the risk of multiple adverse outcomes. Prior research into its predictive validity is limited to a handful of studies conducted with the START:AV pilot version and often by the instrument’s developers. The present study examines the START:AV’s field validity in a secure youth care sample in the Netherlands. Using a prospective design, we investigated whether the total scores, lifetime history, and the final risk judgments of 106 START:AVs predicted inpatient incidents during a 4-month follow-up. Final risk judgments and lifetime history predicted multiple adverse outcomes, including physical aggression, institutional violations, substance use, self-injury, and victimization. The predictive validity of the total scores was significant only for physical aggression and institutional violations. Hence, the short-term predictive validity of the START:AV for inpatient incidents in a residential youth care setting was partially demonstrated and the START:AV final risk judgments can be used to guide treatment planning and decision-making regarding furlough or discharge in this setting.

De vraag rijst dan hoe daar in de crisiscommunicatie en het crisismanagement effectief mee om te gaan. Uit literatuuronderzoek en een analyse van een viertal Nederlandse casus blijkt dat, hoewel sommige officiële instanties nog steeds verrast kunnen worden door de snelle stroom van berichten en de effecten die dat met zich meebrengt, er al veel is geleerd over het omgaan met en benutten van sociale media in crisissituaties. Professionals dealing with crises are more or less forced to a next level of crisis communication and crisis management. This is because of the influence of social media. Messages on Twitter, Facebook and other social media can have a significant impact on the course of developments during a crisis. Sometimes in a positive way, when help is mobilized quickly and people can be informed almost instantly. On other occasions the impact is more negative, when for instance rumors lead to false accusations or threats. In the past several years, crisis management authorities have built up more experience with the use and application of social media and monitoring tools. There are still cases where officials and professionals are taken by surprise because of the shift stream of messages and their impact on public opinion and crisis control. But also lessons have been learned, e.g. in terms of online and offline reactions, cooperation with the public, and rumor control. This article gives an overview of research results in literature and summarizes the outcomes of a case study research project
