Training cognitive flexibility in patients with anorexia nervosa: a pilot randomized controlled trial of cognitive remediation therapy.
OBJECTIVE Inefficient cognitive flexibility is considered a neurocognitive trait marker involved in the development and maintenance of anorexia nervosa ( AN ) .  Cognitive Remediation Therapy ( CRT ) is a specific treatment targeting this cognitive style . The aim of this study was to investigate the feasibility and efficacy ( by estimating the effect size ) of specifically tailored CRT for AN , compared to non-specific cognitive training . METHOD A prospect i ve , r and omized controlled , superiority pilot trial was conducted . Forty women with AN receiving treatment as usual ( TAU ) were r and omized to receive either CRT or non-specific neurocognitive therapy ( NNT ) as an add-on . Both conditions comprised 30 sessions of computer-assisted ( 21 sessions ) and face-to-face ( 9 sessions ) training over a 3-week period . CRT focused specifically on cognitive flexibility . NNT was comprised of tasks design ed to improve attention and memory . The primary outcome was performance on a neuropsychological post-treatment assessment of cognitive set-shifting . RESULTS Data available from 25 treatment completers were analyzed . Participants in the CRT condition outperformed participants in the NNT condition in cognitive set-shifting at the end of the treatment ( p = 0.027 ; between-groups effect size d = 0.62 ) . Participants in both conditions showed high treatment acceptance . DISCUSSION This study confirms the feasibility of CRT for AN , and provides a first estimate of the effect size that can be achieved using CRT for AN . Furthermore , the present findings corroborate that neurocognitive training for AN should be tailored to the specific cognitive inefficiencies of this patient group
