From: Attachment security, verbal ability, and inhibitory control in middle childhood

Step Inc. R2 F-change β t-value sr2
Step 1 .11 9.38***    
 Age    .23 3.02** .23
 Sex    − .23 − 3.08** − .23
Step 2 .02 3.77*

  1. The coefficients shown are those in the final model, while accounting for all other predictors. Child sex is coded: − 1 = girl; 1 = boy
  2. F-security = perceived attachment security with father
  3. p < .1; *p < .05; **p < .01; ***p < .001. Final model: R2 = .11; F(3, 156) = 7.57, p < .001
