Hazan and Shaver (1987) researched the link between infant or childhood attachment types and adult relationships. They found that securely attached children, who had secure and close relationships with their parents, developed secure, stable and loving relationships with their adult partners. Insecure-avoidant children, who had cold and rejecting mothers, developed insecure adult relationships with high levels of jealousy and fear of rejection. This shows that childhood attachment styles correlate strongly with adult relationship styles, however the research is based on a self-report questionnaire with retrospective questions that try to explore childhood attachments through the participant’s own (biased) childhood memories.
