Phase 1 Open Trial of Attention and Interpretation Modification (AIM) for Anxiety Disorders in Primary Care

The primary goals of our 3-year, 2-phase project are to develop AIM for primary care linkage and assess its feasibility and acceptability. This protocol description only pertains to Part A (treatment development) and B (open trial).

As it is essential that AIM is eventually implementable in practice settings, we integrate implementation methods in our early development work. We will develop AIM to meet an existing need (low-intensity anxiety disorder treatment), ensure that it fits our local setting, and identify eventual implementation barriers and facilitators via an open pilot trial. We will strive to develop and pilot AIM in a manner that is perceived as compatible with existing practices, simple to use, advantageous relative to existing practice, and beneficial. In order to conduct ongoing evaluation, a team of "end users," including Primary Care Physicians (PCPs), nurses, patients and practice leaders at the Family Care Center (FCC) of Memorial Hospital of Rhode Island, our study site, and at other sites in Rhode Island and Massachusetts, will participate on an Advisory Panel (AP).

Part A: develop AIM including a: 1) personalization computer program that will create an idiographic stimulus set for each participant to be used in the treatment; 2) self-administered, personalized, Cognitive Bias Modification treatment; and 3) protocol for primary care linked delivery.

Part B: an open trial of AIM comprising 3 iterations of 6 patients each. After each iteration, our study team and the AP will review data on feasibility and acceptability of AIM and delivery methods, and make revisions as needed. 8 primary care patients with primary Generalized Anxiety Disorder, Social Anxiety Disorder, and/or Panic Disorder (with or without Agoraphobia) will be enrolled, in 3 iterations. Full assessments will occur pre- and post-treatment. Weekly measures of anxiety and depression will be collected, as will feedback from patients and PCPs about the research and delivery procedures. At the end of the 1st iteration (n=6), the research team and AP will discuss and compare our actual data to the target outcomes. Target outcomes were chosen on face validity, clinical experience, and, when available, relevant literature (e.g., efficacy target based on previous trials and what we deemed clinically meaningful change for low-intensity treatment). Deviations from target outcomes will prompt investigation and discussion, and possible revision of AIM or of research procedures. After revision, we will recruit 6 new patients for the 2nd iteration. At the end of this iteration, the team and AP will review data and make changes as needed. We will repeat this process in the 3rd iteration (n=6).

Part C will include a randomized controlled trial of the final protocol.
