Instagram announced it was "running a test" on some users, a couple months after rumors first emerged that the photo-sharing platform was testing such a feature. Hiding the number of likes is designed to put "focus on the photos and videos you share, not how many likes they get"
This systematic review assessed the current evidence base of substance use prevention programs for Indigenous adolescents in the USA, Canada, Australia and New Zealand.
This study examined the secondary mental health outcomes of two contrasting alcohol prevention approaches, whereby one intervention targets common underlying personality risk for alcohol use and mental health problems (Preventure) and the other targets alcohol- and drug-related behaviours and cognitions (Climate Schools).
U.S. Surgeon General Vice Adm. Jerome M. Adams issued an advisory today stressing the importance of protecting children from a lifetime of nicotine addiction and associated health risks by immediately addressing the epidemic of youth e-cigarette use.
Several school-based prevention programmes have been developed and used to prevent, delay, or reduce substance misuse, and related problems among community samples of adolescents.
The Canadian Institute of Health Research has awarded the ProVenture project led by Dr Stéphane Potvin and Dr Patricia Conrod funding for five years. This longitudinal neuroimaging study aims to investigate the effects of cannabis on the development of psychosis in youth.
Going from an occasional user of marijuana to a weekly or daily user increases an adolescent’s risk of having recurrent psychotic-like experiences by 159%, according to a new Canadian study published today in the Journal of Child Psychology and Psychiatry. The study also reports effects of marijuana use on cognitive development and shows that the link between marijuana use and psychotic-like experiences is best explained by emerging symptoms of depression.
Thanks to an exemplary two million dollar donation by the RBC Royal Bank, CHU Sainte-Justine can now lay the foundation for its mental illness detection program in schools. Based on a model that has gotten good results in a number of countries, this innovative program will be rolled out in 30 high schools in Greater Montréal.
The stepped wedge cluster randomised trial is a novel research study design that is increasingly being used in the evaluation of service delivery type interventions. The design involves random and sequential crossover of clusters from control to intervention until all clusters are exposed.
Onset of alcohol use by 14 relative to 21 years of age strongly predicts elevated risk for severe alcohol use problems, with 27% versus 4% of individuals exhibiting alcohol dependence within 10 years of onset.
Previous work has revealed that interventions aiming to reduce adolescent binge drinking commonly focus on cognitive attitudes, but are insufficiently effective in changing binge-drinking intentions. The focus on these cognitive attitudes might be the reason for this insufficient success.
The large amount of vocational community college students that continue showing binge-drinking behavior might be an indication that interventions targeting this behavior have not been hugely successful. It might be that these interventions targeted beliefs that are less or not related with vocational community college binge-drinking behavior.
The opioid misuse and overdose crisis touches everyone in the United States. In 2016, we lost more than 115 Americans to opioid overdose deaths each day, devastating families and communities across the country. Preliminary numbers in 2017 show that this number continues to increase with more than 131 opioid overdose deaths each day.
Project aim. We will i) describe neural and cognitive functions implicated in adolescent onset depressive symptoms, and their involvement in transition to major depression and in treatment response, allowing to ii) provide novel cognitive and/or neural intervention components for at-risk adolescents, using a targeted and neurodevelopmentally-informed framework.
The authors sought to model the different trajectories of psychotic‐like experiences (PLE) during adolescence and to examine whether the longitudinal relationship between cannabis use and PLE is mediated by changes in cognitive development and/or change in anxiety or depression symptoms.
