259 mother-infant dyads participated in a study linking adult attachment styles to physiological arousal and maternal sensitivity. The data includes measurements from the Adult Attachment Interview during pregnancy and physiological data (RSA and SCL) and sensitivity ratings collected during the Still Face Procedure when infants were 6 months old. The dataset was authored by Esther Leerkes and is hosted on Harvard Dataverse.
Use Cases
- Modeling indirect effects of adult attachment states of mind on maternal sensitivity based on physiological pathways described in the study.
- Analyzing dynamic changes in respiratory sinus arrhythmia (RSA) and skin conductance level (SCL) across episodes of the Still Face Procedure.
- Investigating the relationship between dismissing states of mind and dampened physiological arousal during mother-infant challenges.
- Examining the association between dynamic variability in SCL and higher maternal sensitivity scores.
Strengths
- Data is based on a sample of 259 mother-infant dyads, providing a substantive cohort for analysis.
- Includes multi-method assessment combining interview-based attachment measures, physiological data (RSA, SCL), and behavioral sensitivity ratings.
- Longitudinal design with data collected during pregnancy and again when infants were 6 months old.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect temporal and demographic bias inherent to the specific study cohort.
