A 12-item version of the Eating Attitudes Test (EAT-12) was constructed and applied at 1-year intervals in a non-referred cohort of 1193 adolescents in Norway aged 13-18 years. Eight percent of the girls scored beyond the chosen cut-off point of 9/10 the first time and 9% the second time. Factor analysis demonstrated 3 factors--dieting, bulimia and food preoccupation and oral control. Both the total scores on the EAT-12 and the 3 different factor scores showed a significant relationship between eating behaviour and smoking, level of alcohol consumption, alcohol intoxication, psychopathology and parental bonding.
