In one research study, 358 participants took part in a 5-week randomized controlled trial where they were split up into three groups. The first third of participants used eQuoo, the second third used a ‘Treatment as Usual’ CBT Journal application, and a third group was put on a waitlist and did not receive any intervention. Throughout the three weeks, all participants took the following questionnaires at three different time points – The Adult Resilience Scale, The Personal Growth Inventory Scale, the Psychological well-being: Positive Relations With Others Scale by Ryff and a 1 Item Anxiety Likert scale. Those in the eQuoo group showed statistically significant increases in metrics focused on wellbeing and significant decreases in anxiety, based on repeated measures. Participants also were seen to have increased resilience, personal growth, and positive relations with others. (Litvin, Silja, Maier, M.A., Lüttke, S., Saunders, R.
