Insights
Infants with cleft lip and palate (CLP) show secure attachment initially but develop more avoidance and deactivation over time, indicating potential vulnerabilities in parent-infant relationships and emotional development.
Area of Science:
- Developmental Psychology
- Pediatric Health
- Attachment Theory
Background:
- Cleft lip and palate (CLP) is a common perinatal condition affecting parent-infant bonding.
- Understanding the long-term impact of CLP on infant emotional development is crucial.
Purpose of the Study:
- To examine attachment quality changes in infants with CLP over time.
- To investigate the effects of CLP on parent-infant relationships and infant emotional development.
Main Methods:
- Prospective longitudinal study design.
- Strange Situation Paradigm (SSP) administered at 12 months.
- Attachment Story Completion Task (ASCT) administered at 4 years.
- Comparison between CLP infants (n=38) and healthy controls (n=17 at 12 months; n=32 and n=14 at 4 years, respectively).
Main Results:
- CLP infants displayed secure attachment (55%) similarly to controls at 12 months.
- CLP infants showed increased avoidance and less proximity seeking.
- At 4 years, CLP children exhibited more deactivation and less security than controls.
- Nearly 60% of CLP children with distal strategies at 12 months showed deactivation or disorganization by 4 years.
Conclusions:
- While CLP infants may appear securely attached early on, they exhibit subtle differences indicating future vulnerabilities.
- Attachment strategies in CLP infants evolve, with a significant shift towards deactivation or disorganization by age 4.
- Early subtle attachment differences in CLP infants predict later emotional and relational challenges.
Abstract:
This study examines the attachment quality and how this changed over time among infants who had cleft lip and palate (CLP), by conducting a prospective longitudinal study addressing the effects of this type of perinatal event on the parent-infant relationship and the emotional development of the infants. At 12 months of age, the Strange Situation Paradigm (SSP; M. Ainsworth, M.C. Blehar, E. Waters, & T. Wall, 1978) was administered to a sample of 38 CLP infants (born between 2003 and 2010) and 17 healthy controls. At 4 years of age, the Attachment Story Completion Task (ASCT; I. Bretherton, D. Ridgeway, & J. Cassidy, 1990) was administered to 32 individuals from the CLP sample and 14 from the control group. As reported in the literature, CLP infants display secure attachment behaviors as frequently as do control infants (55%). However, a more detailed analysis of the attachment scales revealed that CLP infants show more avoidance and less proximity seeking. In addition, a closer examination of the subcategories of attachment styles revealed that most CLP infants (71%) displayed distal attachment strategies such as the B1/B2 or A1/A2 subcategories. At 4 years old, CLP infants clearly displayed more deactivation and less security than did the control sample. Moreover, when detailing the evolution of attachment individually, almost 60% of the CLP children showing distal strategies at 12 months became deactivated or disorganized when they reached 4 years. Indeed, subtle differences in attachment behaviors at 12 months old-which can be considered marginally secure at that age-may reveal attachment vulnerabilities, which seem to be more apparent over the course of development.
