“…This means that in addition to KS patients, also NKS patients are at risk that their apparently "without cognitive complaints" appearance on self-report questionnaires can be easily overlooked or misinterpreted as a lack of motivation by the therapist (Rinn et al, 2002) leading towards under diagnosis or inadequate treatment (Horton et al, 2015;Thomson et al, 2012). Studies in different patient groups show that self-report is moderately correlated with performance tasks (Carone and Ben-Porath, 2014;Gervais et al, 2009), indicating that it is difficult to measure self-awareness impairment with self-report questionnaires only. Therefore, in addition to a heteroanamnesis, information on cognitive functioning is essential in the treatment of patient with chronic alcohol use.…”
