简要总结
In the phase 1 of the SPEAC project the specific aims are to: (1) establish the functionality, usability, and treatment fidelity of Lumen using iterative, user-centered design, development, and formative evaluation; and (2) demonstrate feasibility, acceptability, and target engagement in a 2-arm pilot RCT. The aim 1 focuses on developing a voice-enabled, artificial intelligence (AI) virtual agent, named Lumen, trained in Problem Solving Therapy (PST) via an iPad-based application. The development of Lumen will employ iterative user-centered design-evaluation cycles. After the functionality, usability and treatment fidelity of Lumen are established, in the aim 2, we will conduct a 2-arm randomized clinical trial (RCT, Study 1) to pilot test Lumen.
详细描述
60 participants with eligible depression and/or anxiety (n=60) will be randomized in a 2:1 ratio to the Lumen treatment arm (n=40) or the wait-list control arm (n=20).
Participants in both arms will receive encrypted study iPads.
Lumen treatment arm participants will receive encrypted study iPads to complete PST with Lumen (8 sessions, 4 weekly and then 4 biweekly, over 12 weeks) or be on a wait list. Participant permission will be obtained to record their PST sessions with Lumen, which will be independently rated by PST experts for fidelity. Lumen treatment arm participants will also complete the depressive and anxiety symptoms assessment questionnaires at the start of each PST session, and a participant survey of usability, user experience and therapeutic alliance at the end of each PST session.
Participants in both arms will complete measurements of neural target engagement and treatment outcomes at both baseline (0 week) and 16 weeks.
These assessments will include (1) functional magnetic resonance imaging (fMRI) 2) Surveys of PST (3) Surveys of patient-reported outcomes, such as depressive and anxiety symptoms, social functioning, and health-related quality of life. Participants also will complete naturalistic end-of-day assessments of mood, stress, appraisal, and coping for 7 days every 2 weeks (on weeks 0, 2, 4, 6, 8, 10, 12, 16) - that is, 8 time series.

结局指标
主要结局
Change in Activation of Left Amygdala From Baseline Functional Magnetic Resonance Scan at 16 Weeks
时间窗: Baseline, 16 weeks
Two neural targets defined a priori, specifically activation of the amygdala for nonconscious threat-related emotional reactivity and activation of the DLPFC for cognitive control will be assessed using fMRI. In the facial emotion viewing paradigm, facial expression stimuli are standardized black and white photographs of 8 identities (4 female, 4 male) with evoked expressions of threat-related emotions (fear, anger), sad-related emotions (sadness) and reward-related emotions (happiness), along with neutral. To assess amygdala activation for the negative affect circuit, our analysis focused on threatening faces only. Threat stimuli included a combination of fear and anger stimuli relative to neutral blocks. For the Go-NoGo paradigm, the 'Go' and 'NoGo' stimuli are presented for 500 ms each with an inter-stimulus interval of 750 ms. Higher score indicates higher activation of the amygdala and DLPFC.
