Parameter estimates (path coefficients) of additive genetic (A) and non-shared environmental (E) influences from bivariate biometric model-fitting of liability for disordered gambling as defined by the DSM-IV (DSM-IV DG) and South Oaks Gambling Screen (SOGS) in which the estimates for men and women were constrained to be equal. (Proportions of variation in risk for DSM-IV DG and SOGS attributable to each factor can be obtained by squaring the path coefficient). 95% confidence intervals are in parentheses
