When applied to the school setting, interventions are only two 90-min group sessions facilitated by a trained facilitator and co-facilitator, with a minimum of 1 week between sessions [60, 61, 62•, 63•]. Youth with similar personality profiles are grouped together to complete personality-specific interventions targeting their most salient personality profile. In more clinically oriented settings, such as psychiatry clinics or special education institutions, where youth might suffer from more severe learning difficulties or psychiatric comorbidity, interventions can be broken down into multiple briefer intervention sessions, which can be delivered in a group or individual format, depending on the individual needs of the client. In addition, a very novel treatment delivery approach [44, 64] recruited participants living with anxiety disorders from the community and simply mailed treatment manuals to their homes. Intervention sessions were conducted individually with the assistance of a coach who is available to participants by telephone or email.
