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

Implementation of digital behavioral health programs in primary care (PC) can improve access to care for patients in need.

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.

Adults aged 20-65 years with at least mild anxiety (GAD-7 ≥ 5) 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.

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 (β = -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.

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).

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.
