Implementation of a Guided, Digital Cognitive Behavioral Program for Anxiety in Primary Care: Preliminary Findings of Engagement and Effectiveness

Background:Implementation of digital behavioral health programs in primary care (PC) can improve access to care for patients in need.Introduction:This study provides preliminary data on user engagement and anxiety symptom change among patients referred by their PC provider to a guided, mobile cognitive behavioral program, Lantern.Materials and Methods:Adults aged 20-65 years with at least mild anxiety (GAD-75) during routine clinical screening in two PC practices were offered Lantern. The primary outcome was self-reported anxiety collected at baseline and 2 months. Linear mixed effects modeling was used to examine anxiety symptom reduction from baseline to 2 months. Post hoc analyses evaluated how number of units completed, number of techniques practiced, and days of usage impacted symptom change.Results:Sixty-three participants signed up for Lantern and had both baseline and 2- month GAD-7. A mixed effects model adjusted for age, gender, medical complexity score, and physical health found a significant effect of time on GAD-7 (=-2.08, standard error=0.77, t(62)=-2.71, p=0.009). Post hoc analyses indicated that mean number of units, techniques, and usage days did not significantly impact GAD-7 change over 2 months. However, there was significantly greater improvement in anxiety in participants who completed at least three techniques.Discussion:Results benchmark to previous studies that have found statistically significant symptom change among participants after 4-9 weeks of face-to-face or Internet-based cognitive behavioral therapy (CBT).Conclusions:This study suggests that use of Lantern is associated with anxiety reduction and provides proof-of-concept for the dissemination and implementation of guided, CBT-based mobile behavioral health interventions in PC settings.
