  • Research Question:
    • Is early preventive intervention effective in enhancing parental sensitivity and infant attachment security, and if so, what type of intervention is most successful?
  • Hypotheses:
    • Early interventions are effective (with a larger effect on Emotional AvailabilityEmotional Availability
      The Emotional Availability Scale (Biringen, 2008) measures 6 behavioral aspects on a 1-7 likert-scale:


      Sensitivity (Ainsworth)
      than on attachment security)
    • Type and moment of the intervention matter (most effective: early interventions with a behavioral focus and a small amount of sessions)
  • Method:
    • Meta analysis that looked at 70 intervention studies related to sensitivity, AttachmentAttachment
      , or both
    • all studies had the goal to increase positive parental behavior
  • Results:
    • Which interventions were most effective on motherly sensitivity (ea)
      • Interventions that focused solely on sensitivity and started after the first 6 months
      • with video feedback, less than 16 sessions, no personal contact
      • demographic data had largely no effect
    • Which interventions were most effective attachment security
      • same, but without video feedback
    • Are shorter/behavioral interventions better for problematic families?
      • Yes, long and varied performed worse
      • However! High exclusion rate in control group (maybe do some kind of intervention in both)
    • ==Interventions that increase sensitivity also have a positive effect on attachmentattachment
      security in early childhood (causal relationship)==.
  • Interpretation:
    • Aim for interventions with clear focus and medium amount of session
    • Aim for behavioral interventions that are aimed at motherly sensitivity
