Inventory of Experiences in Close Relationships (YIYE-II)

Inventory of Experiences in Close Relationships-II (IEII): The scale was developed by Fraley and Shaver (2000) and its validity and reliability study in Turkey was conducted by Selçuk et al. The scale has a total of 36 items in a seven-point Likert-type scale, 18 of which are in the anxiety and 18 in the avoidance sub-factor. The score obtained from each subscale ranges between 18 and 126 and it is said that the higher the score obtained from the scale, the higher the avoidant attachment or attachment anxiety. While the Cronbach's alpha coefficient of the avoidance subscale is 0.90, the Cronbach's alpha coefficient of the anxiety subscale is 0.86. The test-retest reliability coefficients for the avoidance and anxiety dimensions of the scale are 0.81 and 0.82, respectively.

The increase in the scores obtained from the scale is interpreted as individuals experiencing anxiety in their relationships and avoiding others.

Participants who completed the scale can be evaluated in terms of anxiety and avoidance dimensions, as well as on the basis of the Quadruple Attachment Model proposed by Bartholomew and Horowitz (1991). Sümer (2006) also suggested that categorical measurements can be taken from the scale by cluster analysis and classifications can be made on the basis of the Quadruple Attachment Model. Accordingly, secure attachment style was defined at low levels of anxiety and avoidance, while fearful attachment style, which is at the opposite pole, was defined at high levels of both dimensions (anxiety and avoidance). The obsessive attachment style was defined with a combination of high levels of anxiety and low levels of avoidance, and the indifferent attachment style was defined with a combination of low levels of anxiety and high levels of avoidance.

According to the quadruple attachment model:

Secure attachment: low levels of anxiety and avoidance
