Design outcomes

Primary

MeasureTime frame
Socioemotional functioning in 18-month-old infants of parents with or without SMI operationalised as visual social attention (%initial look; %attention) obtained via eye tracking.

Secondary

MeasureTime frame
Exploration of differences between offspring from parents with vs. without SMI, using follow-up questionnaires, blood/saliva and hair samples to measure: • parent-child dynamics (over time) • child temperament (over time) • child socioemotional development • PGR scores for SMI • Hair cortisol levels And explore the role of these factors in social-emotional functioning as measured by eye-tracking (i.e., primary endpoint).
