“…In this study, a broad definition of disability including different types of disabilities and chronic conditions was used, thus constituting a relatively heterogeneous group of adolescents with disabilities. However, one argument for having this broad definition is that it seems to exist comorbidity between different disabilities and chronic conditions, and in turn with having different forms of learning disabilities (Blood et al, 2003; Kaczmarek et al, 2016; Pavlou & Gkampeta, 2011; Wassenberg et al, 2010). Nevertheless, some of the research presented in the introduction have been conducted with specific types of conditions (e.g., ADHD or diabetes), which may affect the comparability between our results and this type of research.…”
