The Adult Attachment Scale (AAS) was officially developed in 1990 but built on the earlier work of Hazen & Shaver (1987) and Levy & Davis (1988). The scale was developed by decomposing the original three prototypical descriptions (Hazen & Shaver, 1987) into a series of 18 items.
The scale consists of 18 items scored on a 5 point likert-type scale. It measures adult attachment styles named “Secure”, “Anxious” and “Avoidant”, defined as:
• Secure = high scores on Close and Depend subscales, low score on Anxiety subscale
• Anxious = high score on Anxiety subscale, moderate scores on Close and Depend subscales
• Avoidant = low scores on Close, Depend, and Anxiety subscales
Aligning theoretical framework, gathering articles, synthesizing gaps, articulating a clear methodology and data plan, and writing about the theoretical and practical implications of your research are part of our comprehensive dissertation editing services.
The 18 items that compromise the measure are as follows:
Note: (S)= Secure, (Av)= Avoidant, (Ax)= Anxious/Ambivalent

Reliability and Validity
Collins & Read (1990) reported Cronbach’s alpha coefficients of .69 for Close, .75 for Depend, and .72 for Anxiety. Test-retest correlations for a 2-month period were .68 for Close, .71 for Depend, and .52 for Anxiety.
