Background:
During the pandemic, a randomized controlled trial (RCT) of Mindfulness-Based Stress Reduction (MBSR) versus the antidepressant, escitalopram (ESC) added a second phase using a synchronous, videoconference (VC) format for both interventions, enabling randomized and naturalistic comparisons. The original in-person RCT demonstrated non-inferiority of MBSR to ESC. In the second phase, we hypothesized that MBSR-VC would be non-inferior to ESC-VC, and that MBSR-VC would be non-inferior to in-person MBSR (MBSR-IN).
Methods:
Adults with anxiety disorders were recruited for a 3-center RCT. Primary (Clinical Global Impression of Severity: CGIS) and secondary outcomes (satisfaction, other measures for anxiety subtypes) were compared between MBSR-IN vs MBSR-VC, ESC-IN vs ESC-VC and MBSR-VC vs ESC-VC.
Results:
MBSR-VC (n = 100) and ESC-VC (n = 102) did not significantly differ in mean CGI-S change at endpoint (1.39 vs 1.51, p = 0.17) but non-inferiority of MBSR-VC was not supported. MBSR did not vary by delivery format (VC: 1.3 vs. IN: 1.3, p = 0.77) and MBSR-VC's non-inferiority to MBSR-IN was demonstrated within the pre-specified margin of -0.40 (95 % CI: -0.34 to 0.25). ESC-IN and ESC-VC were not significantly different in CGI-S change in unadjusted comparisons (1.4 vs 1.5, p = 0.53), but the average CGI-S at endpoint was significantly lower in the ESC-VC group in a multivariable longitudinal model. Other findings included in-person treatments having a greater impact on social anxiety compared to their VC version, ESC-VC having higher satisfaction ratings and a greater impact on panic symptoms than MBSR-VC.
Conclusions:
Remotely delivered MBSR demonstrated comparable effectiveness to in-person MBSR for anxiety disorders, providing support for this delivery approach. Social anxiety symptoms improved more with in-person care.
