” Total scores

range from 24 to 120, with higher scores indicating greater disordered eating-related cognitions. Despite its original focus on clients with AN (Mizes, 1990), the MAC-R was found to be an adequate measure for assessing disordered eating cognitions endorsed by patients diagnosed with other eating disorders (Mizes et al.). In a previous study with clinical samples of various eating MI-773 mouse disorders (Mizes et al.), an alpha coefficient for the MAC-R was .90. Emotional eating was measured by the Emotional Eating Scale (EES; Arnow, Kenardy, & Agras, 1995). The EES is a 25-item self-report measure. Each item consists of an emotion term (i.e., “angry,”“lonely,”“irritated”). Using a 5-point scale ranging from 0 (no desire) to 4 (overwhelming urge), the individual rates the extent to which experiencing that emotion occasions eating behavior. Scores Selleckchem PD0325901 range from 0 to 44 on the EES anger subscale, 0 to 36 on the anxiety subscale, and 0 to 20 on the depression subscale, with greater scores suggesting greater emotional eating. Previous studies have revealed that the EES has adequate internal consistency in clinical samples with obesity, with Cronbach’s

alphas of .78, .78, and .72 for anger/frustration, anxiety, and depression subscales, respectively ( Arnow et al., 1995) and nonclinical samples with Cronbach’s alphas of ..87, .84, and .80 for the anger/frustration, anxiety, and depression subscales respectively ( Waller & Osman, 1998). Functional impairment due to disordered eating was measured by the Clinical Impairment Assessment 3.0 (CIA 3.0; Bohn et al., 2008). The CIA 3.0 is not a 16-item, self-report

measure designed to assess psychosocial impairment due to disordered eating features in the past 28 days (Bohn et al., 2008). Items are rated on a 4-point Likert-like scale, ranging from 0 (not at all) to 3 (a lot). A CIA 3.0 global score is calculated as a severity index, ranging from 0 to 48 with greater scores suggesting greater impairment. The CIA 3.0 has demonstrated high levels of internal consistency with a Cronbach’s alpha of .97 ( Bohn et al., 2008). Initial contact was made by telephone or electronic mail at which time the initial assessment was scheduled. All measures were completed during this initial session. Participants were asked to monitor binge eating for up to 3 weeks prior to treatment. Both participants then completed the 10-week ACT intervention. The second author served as the therapist for both participants. They completed the same measures administrated at pretreatment at mid-point. After completing the 10-week treatment portion of the study, participants were asked to monitor their binge eating for one additional week and complete the study measures again. They were again asked to monitor their target behaviors for 1 week and complete all measures at the 3-month follow-up. The manualized ACT protocol consisted of 10 weekly 50-minute individual therapy sessions.
