Mind-Mindedness as a Multidimensional Construct: Appropriate and Nonattuned Mind-Related Comments Independently Predict Infant-Mother Attachment in a Socially Diverse Sample

In a socially diverse sample of 206 infant–mother pairs, we investigated predictors of infants’ attachment security at 15 months, with a particular emphasis on mothers’ tendency to comment appropriately or in a non‐attuned manner on their 8‐month‐olds’ internal states (so‐called mind‐mindedness). Multinomial logistic regression analyses showed that higher scores for appropriate mind‐related comments and lower scores for non‐attuned mind‐related comments distinguished secure‐group mothers from their counterparts in the insecure‐avoidant, insecure‐resistant, and insecure‐disorganized groups. Higher scores for appropriate mind‐related comments and lower scores for non‐attuned mind‐related comments also independently predicted dichotomous organized/disorganized attachment. General maternal sensitivity predicted neither attachment security nor organization, although sensitivity was found to relate to dichotomous secure/insecure attachment specifically in the context of low socioeconomic status. The findings highlight how appropriate and non‐attuned mind‐related comments make independent contributions to attachment and suggest that mind‐mindedness is best characterized as a multidimensional construct.
