It is common knowledge that correlation does not imply causation. Though the independent variable is the type of attachment (and its security) and the dependant variable is the well-being of the child later on in life, it is not to say that one causes the other. The IV helps predict the DV but does not completely determine it, but there are other things that need to be considered. The type of environment and the experiences the child goes through plays a large part in determining their well-being later on in life. If the child is raised in a stable environment, this can help shape their well-being - their physical and emotional health later on. If they do not have any scarring experiences during childhood, they are more likely to grow up having good mental health and a healthy social life. These two factors play a large part inchild development and influence life later on.
I agree completely. The environment someone is placed in when they are growing up makes a great difference on the attachment type as well as their well-being later in life. Because of this, there is no causality proven in correlation given in the prompt. There are too many extraneous factors, including environment, that could be the cause. - CS
