“…The existing studies have consistently highlighted supervisees' non-disclosure or partial concealment of potentially salient information (Hess et al, 2008;Ladany, Hill, Corbett, & Nutt, 1996;Mehr, Ladany, & Caskie, 2010;Webb & Wheeler, 1998;Yourman & Farber, 1996). A wide spectrum of the content of non-disclosures has been indicated, which has included clinical mistakes (Mehr et al, 2010;Walsh, Gillespie, Greer, & Eanes, 2002), issues related to the supervisory relationship (Hess et al, 2008;Ladany et al, 1996;Mehr et al, 2010;Reichelt et al, 2009), personal/countertransference reactions to clients (Hess et al, 2008;Mehr et al, 2010) and personal issues (Mehr et al, 2010). Given the significant content of these non-disclosures, this has important implications for supervision being able to effectively fulfil its clinical governance duties.…”
