“…Stress was most frequently measured with a version of the perceived stress scale [98] (PSS) [46,49,[54][55][56][57]67,68,71,72,74,77,81,87,88,90]. Less frequently measured mental health-related outcomes were psychological distress (n = 4) [69,71,75,78], test anxiety (n = 2) [75,78], and negative affect (n = 1) [85]. Well-being or positive mental health was primarily measured through mental well-being (n = 8) [62,65,66,69,72,77,80,84], most commonly utilising the Warwick-Edinburgh mental well-being scale [99] (WEMWBS) [62,65,69,77,84].…”
