Fig 2. Structural equation model: Actor partner interdependence model with actor and partner GG genotypes predicting anxious attachment.

STD Standardized estimates. a = actor effect, b = partner effect. Letters indicate constrained paths. Also, in the model were associations between husbands’ and wives’ anxious attachment (B = 0.04; p = .57) and husbands’ and wives’ GG genotype (B = 0.03, p = .13). Model accounts for 3% of the variance in husbands’ and wives’ anxious attachment.
