Table 1.
Measure/Scale | Cut-off point | Psychometric properties |
---|---|---|
ANIS | ≥ 65 | Cronbach's α ranged from 0.80 to 0.90. In the three samples the ANIS total score correlated 0.41 to 0.51 with the 28- item General Health Questionnaire, and 0.15 to 0.26 with the percentage of ideal body weight [184] |
BEDS-7 | – | Cohen’s Kappa = 0.827 [185]. Sensitivity = 100%, specificity = 38.7% [186] |
DEBQ | – | Cronbach's α ranged from 0.80 to 0.95. All Pearson’s correlation coefficients assessing interrelationships between scales (for restrained, emotional, and external eating) were significant, indicating that the measures have a high internal consistency and factorial validity [187] |
EAT-26 | ≥ 20 | Cronbach's α = 0.90. EAT-26 correlates highly with the original EAT-40 scale (r = 0.98) |
EAT-40 | 30 | Cronbach's α = 0.94. Sensitivity = 35.3%, specificity = 88.8%, positive predictive value = 24.0%, and negative predictive value = 93.2% [182] |
EDDS | 16.5 |
Cronbach's α = 0.89. Anorexia nervosa: Sensitivity = 93%, specificity = 100%, positive predictive value = 93%, negative predictive value = 100% Bulimia nervosa: Sensitivity = 81%, specificity = 98%, positive predictive value = 97%, negative predictive value = 96% Binge-eating disorder: Sensitivity = 77%, specificity = 96%, positive predictive value = 95%, negative predictive value = 93% |
EDE-Q | ≥ 4 |
Cronbach's α for the global score = 0.90 Women diagnosed with eating disorders scored significantly higher on the EDE-Q than the control women (sensitivity = 0.83, specificity = 0.96, positive predictive value = 0.56) [188, 189] |
EDI | ≥ 50 | Cronbach's α ranged from 0.82 to 0.90. Sensitivity = 52.9%, specificity = 85.2%, positive predictive value = 26.4% |
EDS-5 | – | Cronbach's α ranged from 0.83 to 0.86. Sensitivity = 0.90 and specificity = 0.88 |
ORTO-11 | < 25 | Cronbach's α ranged between 0.74 and 0.83. Sensitivity = 75% and specificity = 84% [190] |
ORTO-15 | < 40 | Cronbach's α = 0.83. The ORTO-15 showed significant associations with eating psychopathology (EAT-26 and SR-YBC-EDS; range r = 0.64 – 0.29; p < 0.05) [191] |
Q-EDD | - | Cohen’s Kappa = 0.94. Sensitivity = 0.97, specificity = 0.98, positive predictive power = 0.94, and negative predictive power = 0.99 |
SCOFF | ≥ 2 | kappa statistic = 0.82. Sensitivity = 100%; specificity = 87.5%; and positive predictive value = 90.6% |
WCS | ≥ 52 | Cronbach's α = 0.65, 0.61, and 0.63 at ages 5, 7, and 9 years [192]. Skewness values for all items ranged from 0.02 to 0.95; and Kurtosis values ranged between -0.83 and -0.53 [193] |
