Hierarchical Regression Analyses: Mindfulness predicting RT difference scores

Variable	Beta	Partial Correlation
Model 1: Hand context
Step 1: R2 = .03, ΔF(2,82) = 1.11, ƒ2 = .026
Correctness	−.13	−.13
Depression	.08	.09
Step 2: R2 = .03, ΔF(1,81) = .04, f2 = .028
Correctness	−.13	−.13
Depression	.06	.05
Mindfulness	−.03	−.02
Model 2: Shoebox context
Step 1: R2 = .11, ΔF(2,82) = 5.19**, ƒ2 =.126
Correctness	−.32**	−.32
Depression	.06	.06
Step 2: R2 = .19, ΔF(1,81) = 7.61**, ƒ2 = .233
Correctness	−.35**	−.36
Depression	−.19	−.15
Mindfulness	−.37**	−.29

Note: N = 85. The dependent variable is the difference in RTs between negative and neutral trials calculated and entered separately for the hand and shoebox contexts; higher scores indicated a greater effect of stimulus valence on RTs. “Correctness” is the difference in correctness between negative and neutral trials, calculated and entered separately for hand and shoebox contexts; higher scores indicated a greater effect of stimulus valence on correctness. Depression was assessed using the QIDS-SR₁₆. Mindfulness is a composite scale derived from the sum of four FFMQ subscales (describing, acting with awareness, nonjudging, non-reacting).
