“…Participants completed a battery of self‐report measures, including the ED‐15 (Tatham et al, ), and the EDE‐Q (Fairburn & Beglin, ) for the evaluation of the concurrent validity, as well as collateral measures of depression and psychosocial impairment to evaluate the convergent validity of the ED‐15 scales/factors.…”

“…The Eating Disorder‐15 (ED‐15; Tatham et al, ) is a recently developed brief self‐report measure of eating attitudes and disordered eating behaviours specially designed to assess therapeutic progress and outcomes on a weekly basis. Its original version proved to be of clinical utility as a complementary and psychometrically robust measure able to track changes during therapy.…”

“…Its original version proved to be of clinical utility as a complementary and psychometrically robust measure able to track changes during therapy. Moreover, the ED‐15 has the potential to inform clinicians on eating‐related cognitive and behavioural symptoms changes in patients with ED, in a timesaving fashion (Tatham et al, ).…”

Objective The purpose of the current study was to explore the factor structure and psychometric properties of the Portuguese version of the Eating Disorder‐15 (ED‐15), as well as to establish cutoff scores and normative data for the Portuguese version. Methods Participants from a nonclinical sample (N = 860) and an eating disorders clinical sample (N = 260) were invited to complete a set of questionnaires, including the Portuguese version of the ED‐15. Results The first‐order two‐factor structure originally proposed by the ED‐15 authors was endorsed through a confirmatory factor analysis (χ2/df = 2.610; standardized root‐mean‐square residual = 0.0325; root‐mean‐square error of approximation = 0.079; Tucker–Lewis index/goodness‐of‐fit index/incremental fit index > 0.95). Items revealed adequate construct validity (λ = .54–.90; R2 = .29–.81). The ED‐15 revealed excellent internal consistency (α = .91) and temporal stability (intraclass correlation coefficient = .92; 95% CI [.84–.95]). Normative data for the ED‐15 were provided. The ED‐15 demonstrated acceptable concurrent and convergent validity. Receiver operating characteristic analysis revealed that the ED‐15 total score accurately discriminates between participants with and without an eating disorder (area under de curve = .80; SE = .017; p ≤ .001; 95% CI [.766–.834]). A cutoff score for clinical significance and a reliable change index were computed. Conclusions The Portuguese version of the ED‐15 is a reliable and valid measure of eating psychopathology and symptoms, whenever a brief measure is needed, as in session‐by‐session assessment of therapy progress and outcome.

“….4 | ED-15(Tatham et al, 2015) The ED-15 was designed to be reactive to changes in eating pathology over a shorter time period than the EDE-Q and other measures. The original version included items that address: weight/shape concerns, eating concerns, and a single item that measures fear of uncontrollable weight gain when one eats (this last item loads equally on both of the other scales, so is not included in either of them).…”

The Committed Action Questionnaire is an instrument developed to measure committed action, an adaptive psychological process. The main goal in the current study was to confirm the factorial structure of the Portuguese version of the CAQ-8 in a transdiagnostic clinical sample of participants diagnosed with an eating disorder (ED). Participants were 102 female outpatients (M age = 28.1, SD = 10.6; M BMI = 20.0, SD = 5.5) recruited from a clinical setting specialized in the treatment of ED. Confirmatory factor analysis (CFA) was used to confirm the CAQ-8's factorial structure. Both first-and second-order models revealed adequate goodnessof-fit indices (e.g. χ 2 /df = 1.545, p = .06; SRMR = 0.049; RMSEA = 0.073; CFI/TLI > 0.95). A moderation model revealed that the conditional effect of weight, shape and eating concerns on experiential avoidance was significantly moderated by increased levels of committed action, F(3, 97) = 23.79, p < .001, accounting for 42% of the final variance. The present study supports the usefulness of the CAQ-8 as a measure of levels of committed action with patients diagnosed with an ED.
