Measuring attachment security directly: A suggested extension to the two-factor adult attachment construct

This study investigated a three-dimensional model of attachment based on the Relationship Questionnaire (Bartholomew & Horowitz, 1991) and the Relationship Scales Questionnaire (RSQ-R; Griffin & Bartholomew, 1994) in three different samples (n=254, n=129, n=168). Confirmatory factor analysis suggested a three-dimensional model to have better fit than a two dimensional one. The three factors were named Secure/Insecure, Avoidant/Dismissive, and Preoccupied/Anxious. Data from other tests supported the model as a viable alternative to a two-dimensional one. The model was discussed from the view that security/insecurity should be included in a complete measurement model of attachment.
