“…In borderline personality disorder (PD), meta-analyses show that well-structured psychotherapies have a completion rate of about 63% to 75%, which means that a minimum of one in four patients dropped out of treatment before the full potential benefit of treatment was achieved (Barnicot et al, 2012;Barnicot, Katsakou, Marougka, & Priebe, 2011;McMurran, Huband, & Overton, 2010). Although treatment model or treatment setting did not explain differences in dropout in borderline PDs (Barnicot et al, 2011), commitment to change, the therapeutic relationship, and the trait impulsivity appeared to be predicting factors (Barnicot et al, 2012), as also a history of more suicide attempts (De Panfilis et al, 2011;McMurran et al, 2010;Wnuk et al, 2013). Nonetheless, outcomes strongly depend on the operational definitions of dropout, which are quite diverse (Barrett, Chua, Crits-Christoph, Gibbons, & Thompson, 2008;Charnas, Hilsenroth, Zodan, & Blais, 2010;Swift, Greenberg, Whipple, & Kominiak, 2012).…”
