“…Online therapy can be defined as 'any type of professional therapeutic interaction that makes use of the Inter-net to connect qualified mental health professionals and their clients' (Rochlen et al, 2004). The efficacy of online therapy is supported by clinical trials in which it has been compared to waiting-list control groups (Klein & Richards, 2001;Lange et al, 2000;Lange, van de Ven, Schrieken, & Emmelkamp, 2001) and to traditional faceto-face therapies (Cohen & Kerr, 1999;Day & Schneider;2002), and it has been documented for a variety of clinical conditions including post-traumatic stress disorder (Poletti et al, 2020;Backhaus et al, 2012), anxiety disorders (Poletti et al, 2020), depression (de Bitencourt Machado et al, 2016), obsessive-compulsive disorder (Simpson, 2009), panic attacks and agoraphobia (Poletti et al, 2020), bulimia nervosa (Simpson, 2009, de Bitencourt Machado et al, 2016 and mixed diagnoses (Backhaus et al, 2012). Moreover, a number of studies have investigated various aspects of the therapeutic relationship in online therapy, such as therapeutic alliance (Cook & Doyle, 2002;Reynolds et al, 2013) and trust (Fletcher-Tomenius & Vossler, 2009), and have provided qualitative description of online therapy processes William et al, 2009).…”
