Three regression models testing for mediation effects.
Independent variable | Beta | t | Sig. | ||
---|---|---|---|---|---|
Direct effects | Model 1 | AA | −0.185 | −1.715 | 0.088 |
Dependent Variable: CopingAve | DHA | 0.127 | 1.176 | 0.241 | |

Indirect (mediated) effects | Model 2 | AA | 0.326 | 3.085 | 0.002 |
Dependent Variable: CytokineAve | DHA | −0.169 | −1.601 | 0.111 | |
Model 3 | |||||
Dependent Variable: CopingAve | CytokineAve | −0.098 | −1.365 | 0.174 |
n = 194; composite score for CytokineAve and CopingAve computed by averaging across items in respective factors (unit-weighted); AA = red blood cell membrane phospholipid arachidonic acid, measured in micrograms per millilitre of blood (μg/mL); DHA = red blood cell membrane phospholipid docoxahexaenoic acid, measured in micrograms per millilitre of blood (μg/mL).
