Maternal sensitivity and child attachment security in a low SES Peruvian sample: longitudinal relationships.

We tested the generalizability of the sensitivity-security link in a sample of 35 preschooler-mother dyads from a low socioeconomic district in Lima, Peru. We first describe maternal sensitivity and attachment security at two timepoints during early childhood. Second, we investigated the stability of attachment security and maternal sensitivity over a time span of one year. Third, we tested the association between sensitivity and security at each timepoint. Finally, we investigated whether changes in maternal sensitivity predict changes in child security. The results indicated that sensitivity and security were lower than scores reported in the literature for middle-class samples. T2 maternal sensitivity scores were significantly higher than T1 sensitivity scores, and no significant differences were found between T1 and T2 security. Sensitivity and security were associated at both timepoints, after controlling for socio-demographic variables. One-tail test indicated that changes in maternal sensitivity were associated with changes in child security.
