AB  - OBJECTIVE: We examined the etiology of two disordered eating characteristics. 
      METHOD: Participants included 1,470 female adolescent and young adult twins and 
      their female nontwin siblings. Phenotypic factor analyses of a seven-item eating 
      pathology screening tool yielded two factors: weight and shape concerns and 
      behaviors (WSCB) and binge eating (BE). Univariate and bivariate extended twin 
      analyses (including cotwins and nontwin siblings) were used to estimate the 
      magnitude of genetic and environmental influences on these characteristics. 
      RESULTS: Analyses indicated that individual differences in WSCB and BE could be 
      explained by additive genetic influences (a(2) = 0.43 (95% CI: 0.33-0.52) and 0.49 
      (95% CI: 0.36-0.58), respectively), with the remaining variance due to nonshared 
      environmental influences. The genetic correlation between WSCB and BE was 
      estimated at 0.64; the nonshared environmental correlation was estimated at 0.27. 
      DISCUSSION: These results corroborate previous findings on genetic and 
      environmental influences on disordered eating characteristics and suggest that 
      findings can be extended to nontwin populations.
