Reassessing the validity of the attachment Q ‐sort: An updated meta‐analysis
This study corroborates the previous finding that the observer AQS is a valid measure of infant attachment, especially after long periods of observation. The self‐report version showed significantly weaker discriminant and predictive validity.
Highlights
The aim of the study was to update the 2004 meta‐analysis assessing the validity of the attachment Q‐Sort (AQS).
This study broadly replicated the findings of the previous meta-analysis, showing that the observer AQS is a valid measure of attachment.
Caution should be shown in using the self-report AQS due to its comparatively weaker predictive and discriminate validity.
