Acceptability, Usability, and Insights Into Cybersickness Levels of a Novel Virtual Reality Environment for the Evaluation of Depressive Symptoms: Exploratory Observational Study

All analyses were carried out in R supplemented by R Studio (version 2023.12.1.402; R Foundation for Statistical Computing), except for the power calculation for which G*Power (version 3.1; Heinrich Heine University Düsseldorf) was used. Multiple packages were used to supplement analysis and visualization, these include but are not limited to: dplyr [41], vioplot [42], ggplot2 [43], psych [44], rstatix [45], ggeffects [46], ordinal [47], and VGAM [48].

Safety and Efficacy of Modular Digital Psychotherapy for Social Anxiety: Randomized Controlled Trial

Safety and Efficacy of Modular Digital Psychotherapy for Social Anxiety: Randomized Controlled Trial

On the basis of a G*Power analysis for the difference between the groups (2-tailed, 2-sided t test), with an estimated medium effect size (Cohen d) of 0.6, an α level of .05, and 80% power, the required sample size was 45 participants per group. Considering a 10% likelihood of participant dropout, we increased our target sample size to 50 participants per group. Sample sizes for RCT 2 were based on effect size estimates from RCT 1 (Cohen d of 0.47 after 4 weeks).
