Introduction: This study utilizes triadic data to examine the association between motherfather- adolescent concordance (agreement) and discordance (disagreement) on home environment factors (i.e., parental encouragement of dieting, family functioning) and adolescent unhealthy weight control behaviors and binge eating. Method: A subsample of adolescentmother- father triads (n = 833; adolescents ages 10-22) from two coordinated populationbased studies (EAT 2010 and F-EAT) were used. Poisson regression analysis was used to estimate the relative risks of each eating disordered behavior. Results: Triads were more concordant (range 9-42%) than discordant (range 4-24%). Triadic agreement that parents did not encourage dieting was associated with a lower risk of adolescent eating disordered behaviors in some triadic combinations. Additionally, triadic concordance on high family functioning was also associated with a lower risk of adolescent eating disordered behaviors among some triadic combinations. Discussion: Results suggest that triadic concordance on healthy home environment factors is associated with fewer adolescent disordered eating behaviors in some triads. Family based interventions may want to consider focusing on strategies to help move mother-father-adolescent triads closer on seeing the home environment more similarly. Future research is needed on triadic concordance/discordance and disordered eating behaviors to confirm study results and to inform the development of family based interventions.
