and sensation seeking was estimated using maximum likelihood estimation with robust standard errors (MLR) and full information maximum likelihood (FIML) to estimate missing data. Mother-, father-, and adolescent-reported impulsivity loaded on an impulsivity factor and mother-, father-, and adolescent-reported sensation seeking on a sensation seeking factor. Within-reporter error covariances were estimated (e.g., error covariance between mother-reported impulsivity and sensation seeking, and so on). This model fit the data well: χ2(5) = 2.12, p 0.83; RMSEA = 0.00; CFI = 1.00; SRMR 0.01. Standardized factor loadings were significant (p < =0.001) and ranged from 0.52 to 0.71 for impulsivity and from 0.30 to 0.68 for sensation seeking. Within-reporter error covariances were significant (p < 0.001) and ranged from 0.43 to 0.55. The factors were correlated (r = 0.55, p < 0.001).
