New online program aims to ease anxiety in cancer survivors

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age ≥ 18 * A diagnosis of cancer (except non-melanoma skin cancer) ≥ 12 months prior. * No active cancer therapy (excluding chemoprevention) in the past 4 months, and no further therapy planned. * Significant anxiety as evidenced by both of the following * Endorsement of the SCID ( Structured Clinical Interview for the DSM-5) Screener Items for Social Anxiety Disorder, Generalized Anxiety Disorder, Agoraphobia, Specific Phobia, or Illness Anxiety Disorder. * A score ≥ 6 on the Overall Anxiety Severity and Impairment Scale (OASIS). * Regular access to the internet. * Ability to read and write in English. Exclusion Criteria: * Significant symptoms of Panic Disorder in the prior month, including anticipatory anxiety of having a future panic attack or avoidance symptoms associated with panic attacks, as assessed by three SCID-5 items from the panic attack disorder module. * Significant symptoms of Obsessive Compulsive Disorder, as evidenced by any obsessions over the past 3 months, as assessed by three SCID items from the Obsessive Compulsive Disorder module. * Psychiatric hospitalizations or emergency room visits for psychiatric care in the prior 2 years. * In the next two months, intention to use or likelihood of using emergent or "rescue" anxiety medication (e.g., Ativan, Xanax, Valium) or self-prescribed substances (i.e., marijuana) at the onset of anxiety symptoms or when entering a situation where they expect to experience anxiety. * Any significant marijuana use which could impact anxiety symptoms, as evidenced by one of the following: * 4 days of marijuana use in any week in the last month * 20 milligrams of THC (Tetrahydrocannabinol) products in any week in the last month. * Participation in any CBT or ACT-based behavioral or education intervention for anxiety in the past 2 years. This includes in-person, asynchronous, and synchronous online anxiety programs, and therapy that includes these skills. This does not include independent use of any self-help materials (i.e., workbooks, books). * Any impairment (e.g., hearing, visual, cognitive) that interferes with the ability to complete all parts of the study independently.
