Description of intervention features and clinical content of incorporated steps.

Component	Description
Therapy content
Intervention (OASIS)	Collection of 12 steps conceptually linked together to comprise a 12-week online intervention designed to alleviate social anxiety symptoms.
Steps	Steps are composed of interactive therapy modules, each covering a single therapeutic concept and requiring approximately 15 min to complete. In the pathway, all steps were designed to specifically target cognitions and behaviors associated with the maintenance of SAD symptomatology, as per the Clark and Wells model of SAD (20). In addition, three steps were designed to address relevant topics (e.g., intimate relations, self-acceptance, managing negative events) identified via feedback from four lived-experience focus groups. Finally, three steps also addressed clinical considerations specifically relevant to a FEP and SAD comorbid population (i.e., addressing shame, social rank cognitions, and paranoia), as identified in the literature (10–17).
Step content
Key Concepts	Accessible psycho-educational descriptions of therapeutic concepts and outlines based on the purpose of the particular step for the participants.
Comics	Twelve comics (one for each step), each comprising of between 20 to 24 story board panels focusing on a particular therapeutic theme and target related to the treatment of SAD.
Do Its	Unique behavioral experiments known as actions, where the young person can apply therapy content (e.g., reducing and dropping safety behaviors) to relevant real-world situations, to help foster adaptive coping strategies in participants. The ultimate goal of these actions is to increase practice and the generalization of skills to real-life situations by using context-specific, action-based recommendations (28). Actions were designed as two-tiered hierarchal behavioral experiments, that is, individuals had the option to choose a low-intensity entry-level option (option A) or a high-intensity, more challenging (option B) behavioral experiment. Providing individuals who experience SAD with hierarchal options is an important consideration, given the heterogeneity within anxiety disorders in general (30).
Talking Points	Questions are embedded within each of the steps to encourage users to discuss and share their own experiences regarding a specific topic, thereby integrating the social networking component of the intervention and prompting direct interaction.
