Aims:
1. To solicit, curate and preserve data from attachment and parenting intervention research with families, where socioemotional development and parenting and sensitivity have been measured (e.g. variables with pertinence to attachment).
2. To facilitate and conduct Individual Participant Data metaanalysis of the collected data.
3. To contribute to knowledge of the efficacy of parenting interventions where attachment or attachment-relevant assessments such as parental sensitivity have been used as an outcome measure.
4. To contribute to better specified knowledge of mechanisms of change (e.g. sensitivity) and moderators (e.g. child age, temperament) of the efficacy of interventions, in dialogue with theory, e.g. differential susceptibility theory.
