Development and preliminary psychometric evaluation of the Tripartite Attachment Battery

McWilliams, Lachlan & Coveney, Ashley

Mikulincer and Shaver's (2007) model of attachment-system functioning and dynamics in adulthood provided the impetus for developing three self-report measures assessing adult attachment characteristics. These scales are collectively referred to as the Tripartite Attachment Battery (TAB). The Secure Attachment Scale assesses attachment insecurity-security along a single dimension. This is the first self-report measure designed to directly assess attachment security in adults in this manner. The Organized Insecurity Scale includes subscales assessing two specific forms of insecurity: attachment anxiety and attachment avoidance. Unlike other popular measures of adult attachment assessing these constructs, it also includes items that capture secondary attachment strategies related to anxiety (i.e., hyperactivation) and avoidance (i.e., deactivation). The Disorganized Attachment Scale is based on an earlier self-report measure. It captures a more severe form of attachment insecurity characterised by fear, confusion about relationships, and distrust. The process of developing items for these measures is briefly described and an initial psychometric evaluation of each measure is presented. These evaluations were aimed at: (a) assessing the internal consistency of each scale or subscale, and (b) identifying poor items that may need to be removed or modified. A small convenience sample (N = 53) was used. Each measure had a high level of internal consistency, with coefficient alphas ranging from .81 to .93. Recommendations regarding further revising and evaluating the measures included in the TAB are presented.
