Longitudinal Bi-directional Effects of Disordered Eating, Depression and Anxiety.

OBJECTIVE

The present study aims to explore the potentially longitudinal bi-directional effects of disordered eating (DE) symptoms with depression and anxiety.

METHOD

Participants were 189 (49.5% male) adolescents from Melbourne, Australia. DE, depressive and anxiety symptoms were assessed at approximately 15, 16.5 and 18.5 years of age.

RESULTS

Analysis of longitudinal bi-directional effects assessed via cross-lagged models indicated that DE symptoms of eating and shape/weight concerns were risk factors for anxiety. Results also showed that depression was a risk factor for eating concerns.

CONCLUSION

Our findings provide preliminary evidence that preventative measures designed to target concerns about eating and shape/weight might be most efficacious in reducing the transmission of effects between symptoms of DE, depression and anxiety.
