Confronting fear using exposure and response prevention for anorexia nervosa: A randomized controlled pilot study.
OBJECTIVE Anorexia nervosa ( AN ) is a severe illness with high rates of relapse . Exposure and Response Prevention for AN ( AN-EXRP ) is a new approach that specifically addresses maladaptive eating behavior by targeting eating-related fear and anxiety . The aim of this study was to evaluate AN-EXRP as an adjunctive strategy to improve eating behavior during weight restoration , at a pivotal moment when treatment goals shift toward relapse prevention . METHOD A r and omized controlled trial was conducted to compare AN-EXRP with a comparison condition , Cognitive Remediation Therapy ( CRT ) .  Hospitalized patients with AN ( n = 32 ) who had achieved weight restoration to a BMI > 18.5 kg/m(2 ) received 12 sessions of either AN-EXRP or CRT . Outcome was assessed by change in caloric intake in an objective assessment of eating behavior . RESULTS The average test meal caloric intake of participants who received AN-EXRP increased from 352 ± 263 kcal at baseline to 401 ± 215 kcal post-treatment , while that of participants who received CRT decreased from 501 ± 232 kcal at baseline to 424 ± 221 kcal post-treatment [ t(28 ) = 2.5 , p = .02 ] . Improvement in intake was significantly associated with improvement in eating-related anxiety ( Spearman 's ρ = 0.40 , p = .03 ) . DISCUSSION These data demonstrate that AN-EXRP , compared to a credible comparison intervention , is associated with better caloric intake in a laboratory meal over time in AN . Additional studies are required to determine whether incorporation of these techniques into a longer treatment program leads to enduring and clinical ly significant change
