Attachment, the relationship between caregiver and child, is a crucial factor in an infant’s ability to develop healthy relationships. Research has identified different types of attachment relationships. These are known as attachment 'patterns' or 'styles'. The main types of attachment patterns are 'secure' 'insecure anxious' 'insecure avoidant' and 'disorganised'. There are also two different attachment disorders. A disorganised attachment pattern and attachment disorders have been found to predict psychiatric illness, anxiety disorders and depression in later life.
