Subclaims¶

q3 i? Negative life events in fall predicted perceived stress in spring (β=0.12, p=0.05), which predicted self-control decreases from fall to summer (β=−0.12, p=0.001). → Duckworth 2013

q3 · i? · associational · r2

Structural equation model (N=464) with staggered assessments: life events in fall 2010, Perceived Stress Scale in spring 2011, self-control in summer 2011; latent variable adjusted for the scale's low reliability (α=0.53). Model fit: χ2(29)=40.31, p=0.079; CFI=0.98; RMSEA=0.03.

"negative life events assessed retrospectively in the fall predicted perceived stress in the spring (β= 0.12, p= 0.05), which subsequently predicted rank-order decreases in self-control from fall to summer, β=− 0.12, p= 0.001"
