Note: Early Adolescence = ages 9-14 (dummy coded: 1 in “Age Group 1” and 0 in “Age Group 2”), Late Adolescence = ages 15-19 (dummy coded: 0 in “Age Group 1” and “Age Group 2”); Young Adulthood = ages 20-23 (dummy coded: 0 in “Age Group 1” and 1 in “Age Group 2”). Since mixed linear modeling provides unstandardized estimates of predictor effects, the continuous 2D:4D variable was standardized prior to analysis to allow for the interpretation of unstandardized coefficients as standardized coefficients and to ease interpretation of effect sizes. Race/ethnicity was included as a covariate in these analyses but its effects were non-significant (all p's > .05).
