High levels of anxiety are common among young people (Cummings et al., 2014), which represents an emerging public health concern (Johnson & Greenberg, 2013). Youth may be particularly vulnerable to the onset of anxiety difficulties during adolescence, due to marked physiological and psychological changes and exposure to a greater number of novel social and environmental stressors (Costello et al., 2003). It is estimated that around one third of adolescents aged between 13 and 18 years suffer from an anxiety disorder (Merikangas et al., 2010).
