Written exposure therapy and app-delivered mindfulness-based meditation for PTSD and subthreshold PTSD in China: Design of a randomized controlled trial

Reducing intrusive memories and promoting posttraumatic growth with Traveler: A randomized controlled study

Over recent decades, serious games have become a promising intervention approach for addressing psychological problems by providing users with computerized, engaging, and interactive experiences. An innovative serious game, Traveler, has been developed specifically as an intervention tool for managing posttraumatic responses immediately after trauma. The game incorporates the principle of visuospatial interference, the core elements of Tetris, such as spatial displacement and mental rotation, and the critical phases of eye movement desensitization and reprocessing. To test the intervention efficacy and feasibility of Traveler, we conducted a randomized controlled trial involving 105 young adults. Participants were randomly assigned into three groups: a wait-list control group, a group undergoing five-session written exposure therapy, or a group engaging in one session of Traveler gameplay. Outcome measures included intrusive memories (i.e. vividness of traumatic images, disgust at traumatic images, flashback frequency, and flashback impact) and posttraumatic growth measured by the Posttraumatic Growth Inventory. Traveler significantly outperformed the control and written exposure therapy groups in reducing intrusive memories and enhancing posttraumatic growth, with effects persisting at a 30-day follow-up. Thus, Traveler offers a promising brief and early intervention technique for addressing posttraumatic responses. Yet, its clinical applicability requires further investigation.

Meditation Using a Mobile App Improves Surgery Trainee Performance: a simulation-based randomized controlled trial

PURPOSE

To primarily investigate: (1) whether a 10 min instant meditation practice using mobile app could enhance arthroscopy performance and (2) whether a 10-day app-based meditation could reduce short-term arthroscopic skills deterioration.

METHODS

Orthopedic residents with no previous experience in arthroscopy and meditation were randomly assigned to Groups A, B, and C. After initial standard competency-based arthroscopy training on the simulator on Day 1, a pretest was performed via simulator by all participants to assess their initial level of performance, then Groups A and B were required to practice app-based mindfulness meditation 10 min/day for 10 consecutive days, while Group C did nothing. On Day 11, all participants came back to perform a posttest. Prior to the posttest, the participants in Group A practiced app-based meditation (10 min) , whereas Groups B and C had no intervention.

RESULTS

43 participants were included and reached similar level of performance after initial training phase in Day1. In Day11, participants in Group A had statistically better instant arthroscopy performance than Group B, with higher total score (Mean Difference, 3.57; P<.001), less completion time (MD, -42.89s; P=.001), shorter camera (MD, -23.38cm; P<.001) and grasper (MD, -15.23cm; P=.002) path length and less cartilage injury (MD, -1.07%; P=.012). Participants in Group B had less skills deterioration than Group C, with better total score (MD, -5.42; P<.001), less completion time (MD, 51.96s; P=.002), camera path length (MD, 28.41cm; P=.007) and cartilage injury (MD, 1.19%; P=.038).

CONCLUSION

Meditation training using mobile app enhanced instant simulation-based arthroscopy performance and reduced short-term skills deterioration of orthopedic residents with no arthroscopy hands-on experience.

CLINICAL RELEVANCE

Meditation using mobile app for clinicians and educators should be incorporated into simulation-based arthroscopy curriculums and perhaps clinical settings to improve arthroscopy performance and mental health of orthopedic residents without any prior arthroscopy experience.
