Infant crying problems and symptoms of sleeping problems predict attachment disorganization at 18 months

Area of Science:

• Developmental psychology
• Infant behavior
• Attachment theory

Background:

• Infant crying and sleep disturbances are common challenges for parents.
• Understanding early infant behaviors is crucial for assessing developmental trajectories.
• Maternal factors like sensitivity and depressive symptoms can influence infant outcomes.

Purpose of the Study:

• To investigate the longitudinal associations between infant crying, sleep problems, and attachment.
• To explore the moderating roles of maternal sensitivity and depressive symptoms.
• To determine if early infant distress predicts later attachment patterns.

Main Methods:

• Longitudinal study design with 105 healthy infants.
• Parental interviews assessed infant crying and sleep problems at 3 and 18 months.
• Maternal sensitivity observed; attachment assessed using the Strange Situation procedure at 18 months.

Main Results:

• No significant links were found between infant crying/sleep problems and organized attachment (secure, avoidant, resistant).
• Significant associations emerged between infant crying/sleep problems at 3 and 18 months and disorganized attachment.
• Early crying and sleep issues (at 3 months) predicted later disorganized attachment.

Conclusions:

• Infant crying and sleep problems, particularly when present early, may serve as indicators of disrupted infant-caretaker relationship coherence.
• Disorganized attachment is specifically associated with persistent infant crying and sleep disturbances.
• Early identification of these issues could inform interventions to support infant-parent relationships.
