... The CSI has been used in several international studies focusing on different populations, such as adults (Amirkhan, 1990;Bijttebier & Vertommen, 1997;Clark et al., 1995;Gillespie et al., 2000;Huang et al., 2021;Togas & Alexias, 2018), university students (Chin, 2016;Glennon & MacLachlan, 2000;Kao & Craigie, 2013;Kostićet al., 2021;Ptacek et al., 1994;Utsey et al., 2000), patients (Okanli et al., 2017;Smorti et al., 2014;Welch & Austin, 2001;Yıldırım et al., 2018) and adolescents (Pace et al., 2021). In South African studies, the CSI has been used to measure coping in various populations, such as university students (Basson, 2021), adults (Malan et al., 2018;Möller et al., 2017;Myburgh-Jacobsz et al., 2022;Spangenberg & Theron, 1999;Wissing & Van Eeden, 2002), patients (Le Roux & Kagee, 2008), and incarcerated offenders (Duba, 2022;Duba & Jordaan, 2023;Jordaan, 2014;Jordaan & Hesselink, 2022;Jordaan et al., 2018;Langenhoven, 2023;Langenhoven et al., 2024;Pretorius, 2019;Pretorius et al., 2024;Rogers, 2019;Rogers et al., 2024). The South African studies that used the CSI to measure coping amongst incarcerated offenders only reported on the reliability (internal consistency) of the CSI and did not investigate the validity (construct validity) of the CSI within this target population. ...
