“…Many of the screened studies (Charlier and De Fraine, 2012;Allsop and Jessel, 2015;Cózar-Gutiérrez and Sáez-López, 2016;Meletiou-Mavrotheris and Prodromou, 2016;Marques and Pombo, 2019;Sousa and Costa, 2020;Kelleci and Aksoy, 2021;Pflaumer et al, 2021;Mystakidis and Christopoulos, 2022) included very small samples (<100 participants), and most of the studies presented a cross-sectional design. Only four studies (Cózar-Gutiérrez and Sáez-López, 2016;Sousa and Costa, 2020;Gordillo et al, 2021;Pflaumer et al, 2021) included a pre-and post-test research design. Measures were generally both quantitative (self-report questionnaires) and qualitative (open-ended questions, interviews, focus groups); however, the statistical analyses performed were, in most cases, item analyses (descriptive statistics reported in terms of means, frequencies, and percentages) and content analysis for the qualitative explorations.…”
