“…Across different modalities, the two most commonly used delivery formats are in-person, group-based programs and digital programs delivered via the internet (Conley et al, 2013; Davies et al, 2014; Farrer et al, 2013; Rith-Najarian et al, 2019). In-person group formats have demonstrated effectiveness in reducing symptoms of anxiety and depression and range from single-session workshops (e.g., Bentley et al, 2018; Danitz et al, 2016; Eustis et al, 2017) to multiple-session groups (e.g., Bettis et al, 2017; Dvořáková et al, 2017; Greeson et al, 2014; Kaya & Avci, 2016; Topper et al, 2017). Systematic reviews and meta-analyses of digital prevention programs report growing evidence to support the effectiveness of these programs in reducing symptoms of depression, anxiety, and stress, with slightly greater effect sizes among programs that target anxiety specifically (Davies et al, 2014; Farrer et al, 2013).…”
