title: Meta-analytic evidence for stability in attachments from infancy to early adulthood.
abstract: The present meta-analysis integrates results from 127 papers on attachment stability towards mothers and fathers, respectively, from infancy to early adulthood. More than twenty-one thousand attachments (n = 21,072) and 225 time intervals were explored, ranging from half a month to 29 years (348 months). An overall coefficient of r = .39 between times T1 and T2 was obtained, reflecting a medium-sized stability of attachment security. However, no significant stability was found in intervals larger than 15 years. Coefficients are higher for time intervals of less than two years compared to time spans of more than five years, if attachments were assessed beyond infancy using representational rather than behavioral measures and if normal middle class as opposed to at-risk samples were involved. Furthermore, securely attached children at risk were less likely to maintain attachment security whereas insecurely attached children at risk most likely maintained insecurity.
