ATTACHMENT
Synthesis
How important is it?
Attachment is the emotional bond of infant to parent or caregiver. It is described as a pattern of
emotional and behavioural interaction that develops over time, especially in contexts where
infants express a need for attention, comfort, support or security. Parental sensitivity, defined as
the ability to perceive, interpret and react promptly and appropriately to their infant’s signals and
needs, influences the quality of the attachment relationship. According to Bowlby’s attachment
theory, the relationship developed with primary caregivers is the most influential in children’s
lives. A secure relationship not only fosters positive developmental outcomes over time, but also
influences the quality of future relationships with peers and partners.
Secure parent-child relationships help children to regulate their emotion in stressful situations and
explore their environment with confidence. Secure attachment also fosters children’s cognitive,
emotional and language development. Furthermore, children who are securely attached are
predisposed to display positive social behaviours (e.g., empathy and cooperative behaviours)
helping them to develop future positive relationships. On the other hand, insecure and
disorganized attachment put children at increasing risk of problem behaviours and
psychopathologies. Examples include preschool and school-aged aggression, depression, and
socioemotional maladjustment.
What do we know?
Attachment is thought to develop in four phases:

Parent-child attachment relationships are typically assessed with the Strange Situation Procedure,
in which infants’ reactions to being reunited with one of their primary caregivers following a brief
separation are examined. From these interactions, patterns of attachment relationships are
determined. Infants who actively seek proximity with their parents on reunion and communicate
their distress are securely attached. In contrast, infants who avoid their parents or remain
inconsolable on reunion are usually insecurely attached. Some infants display a disorganized
attachment style, characterized by contradictory behaviours toward parents (e.g., strong
avoidance with strong contact-seeking, distress or anger).
Sensitive parenting in the early years plays a key role in the emergence of secure attachments.
For example, parental support, acceptance of the child and sensitive behaviours during joint play
foster a secure attachment. In contrast, domestic violence, frightening, insensitive or neglectful
caregiving or maltreatment are important predictors in the development of attachment insecurity
and disorganization. Changes in parental acceptance or disruption of the family can alter
attachment pathways in either direction, temporarily or permanently.
Studies suggest that day care may have indirect effects on the attachment relationship,
contingent on many factors, such as the social context (familial, cultural, societal) in which day
care is experienced. Indeed, its influence on attachment security has been found to vary across
countries (e.g., Australia, Israel, United States). Its impact is also a function of the quality, type,
timing and quantity of care provided. Although high-quality day care may buffer the negative
effect of parental insensitivity in some cases, the security of child-parent attachment is primarily
guided by the sensitivity of maternal care.
The critical dependence of a child’s adaptive development on the supportive environment
provided by the parent takes on particular importance when considering the millions of families
worldwide that have been forcibly displaced from their homes. These conditions and unusual
levels of stress leave parents with few psychological or physical resources to provide developing

when separated from them; and
4. Infants enter a goal-corrected partnership where they negotiate with caregivers.

children with the environment they need.
What can be done?
Considering the life-long consequences of child-parent relationship quality during the early years,
prevention and intervention programs designed to promote secure attachment are of crucial
importance. That said, there are important factors to take into consideration when implementing
those programs, including their content, duration, behavioural focus and the populations targeted
(at-risk vs. low-risk populations).
The most effective interventions for enhancing attachment security appear to be those targeting
parental sensitivity. Goals usually include building a warm relationship and coaching the parent on
age-appropriate responses to the child’s attachment signals. Several programs use video
feedback to help parents become aware of their interactional style and the needs of their children.
For best results, interventions should be of short duration and implemented when the child is six
months or older. However, for families with multiple problems, longer-term and broader support in
coping with daily hassles may be needed to enable them to focus on sensitivity. As well, an
exclusive focus on parental sensitivity may be neither sufficient nor effective in preventing
disorganized attachment. As such, sustained and intensive home-based interventions are
recommended to reduce disorganized attachment, and should emphasize decreasing or
eliminating atypical caregiver behaviours (e.g., frightening behaviours).
Training in attachment theory and observation is also key for practitioners, and may lead to more
successful assessments and interventions with maltreating parents. For example, the CARE,
Montreal’s Community of practice on Attachment and Relational intervention, offers professionals
monthly group supervision to promote and ensure continuous training.
Finally, it is important to ensure that families at developmental risk, including single mothers, are
provided with the social and financial resources necessary to provide their children with a
supportive environment during infancy. Services provided during this developmental period would
help to prevent the long-term developmental trajectories associated with child psychopathology.
