In addition, YP report high rates of suicidal ideation (16%). While suicidal behavior is a complex phenomenon with many factors and causes, the role of social media is becoming more prominent, especially for YP. Social media has been shown to be a source where YP can find support, but it's also a place where suicidal behavior is glorified or normalized, which can be triggering or harmful to other social media consumers.The #Chatsafe guidelines were developed by Orygen Australia to better equip young people to communicate safely about suicide on social media. These guidelines are supported by a social media campaign to make the content of the guidelines more accessible to them. The #Chatsafe intervention consists of both the guidelines and the social media campaign. A small-scale Australian feasibility study showed promising results in terms of the acceptance and safety of the campaign, and safety regarding communicating about suicide on social media platforms. Currently, in Australia it is tested to what extent these results hold up in a Randomized Controlled Trial (RCT) (Robinson et al., 2023).With funding from the Dutch National Agenda for Suicide Prevention, a contextualized replication study is conducted. The aim of this study is to determine whether the #Chatsafe intervention has an effect on the way in which Dutch YP communicate online about suicide., conditionsModule conditions: Suicide Prevention, conditions: Communication, conditions: Social Media, designModule studyType: INTERVENTIONAL, phases: NA, designInfo allocation: RANDOMIZED, interventionModel: PARALLEL, interventionModelDescription: Participants are randomized to the intervention or the control group using block randomization with varying block sizes (block sizes vary from 2 to 16). The distribution key will be 1:1. The randomization schedule is computer generated by a researcher who will not be part of the analysing researchers., primaryPurpose: PREVENTION, maskingInfo masking: SINGLE, maskingDescription: The research team will be kept blind to randomization. A safety procedure is drawn up in which a senior researcher is appointed who will be unblinded if absolutely necessary. Principally, this will not be needed, since the study psychologists are independently alerted when a subject wants to get in touch., whoMasked: INVESTIGATOR, enrollmentInfo count: 400, type: ESTIMATED, armsInterventionsModule interventions name: Social Media campaign, outcomesModule primaryOutcomes measure: Safe communication about suicide online, secondaryOutcomes measure: Confidence when communicating about suicide online, secondaryOutcomes measure: Willingness to intervene against suicide online, secondaryOutcomes measure: Self-efficacy online, secondaryOutcomes measure: Safety of the #ChatsafeNL materials, secondaryOutcomes measure: Acceptability of the #ChatsafeNL intervention, secondaryOutcomes measure: Safety of the #ChatsafeNL intervention, eligibilityModule sex: ALL, minimumAge: 16 Years, maximumAge: 25 Years, stdAges: CHILD, stdAges: ADULT, contactsLocationsModule locations facility: 113 Suicide Prevention, city: Amsterdam, state: Noord Holland, zip: 1105 BP, country: Netherlands, contacts name: Elke Elzinga, dr, role: CONTACT, phone: 020 3113883, email: e.elzinga@113.nl, contacts name: Saskia Mérelle, dr, role: CONTACT, phone: 020 3113883, email: s.merelle@113.nl, geoPoint lat: 52.37403, lon: 4.88969, hasResults: False
