“…Nine studies (Altshuler et al, 2007; Depp et al, 2012b; Dickerson et al, 2004; Dickerson et al, 2010; Gilbert et al, 2010; Mora, Portella, Forcada, Vieta, & Mur, 2013; Mur, Portella, Martínez-Arán, Pifarre, & Vieta, 2008; Mur, Portella, Martínez-Arán, Pifarre, & Vieta, 2009; Ryan et al, 2013) measured occupational functioning by categorising participants into groups based on their employment status. Of these studies, the most common method involved creating a ‘working vs not working’ dichotomy (Altshuler et al, 2007; Depp et al, 2012b; Dickerson et al, 2010; Gilbert et al, 2010; Mur et al, 2009; Ryan et al, 2013).…”
