I think what cases a correlation to attachement style and well being in later life is a stability of a person's attachment. a person who experience secure attachement style is likely to feel more confidnent and comfortable with later relationships he/she will develop later in life, such as relationship with peers and romantic partners. the ones who experienced anxious/resistant or anxious/avoident attachment styles are likely to keep this manner later in life as well.
screenname: gee4jen I disagree because even if a person has bad experiences as a child does not mean that the person will not have productive relationships as an adult. There are cases in which an adult that was raised in a loving family had issues dealing with other people. An example would be criminals that grew up with the "prefect" life and still could not form healthy bonds with others in their adulthood.
