World Journal of Advanced Research and Reviews, 2023, 18(01), 149–156 Publication history: Received on 22 February 2023; revised on 01 April 2023; accepted on 04 April 2023 Article DOI: https://doi.org/10.30574/wjarr.2023.18.1.0534 Abstract The aim of this study was to adapt and validate the Adult Attachment Interview (AAI), relying on content validity of the AAI, using discourse analysis and test-retest reliability as proposed in the literature. We hypothesized that participants with the same attachment style would use similar semantic systems, and that people who belong to different categories of attachment would use divergent semantic systems. Overall, 20 participants volunteered to take part in this research. The interviews were transcripted, coded and classified following the AAI protocol instructions, relying on the classification and coding system manual. We created a textual corpus composed of the interview transcripts. Each interview was analyzed manually. Of the 20 interviews, 35% were classified as secure attachment style, 50% a dismissing style, 15% and a preoccupied style. The reliability of the AAI classifications was quite high (75%).Results confirmed the relationship between attachment category and representations, In particular, the secure participants tend to be metacognitive, distinguished by a coherent mind and transcript, while dismissive participants exhibited to idealization, passivity of thought and inability to recall, and preoccupied participants prone to an incoherence of mind and transcript, due to their indulgence in talking about the memories of the past, which are still present with all their emotional charge.

Introduction Bowlby's [1] attachment theory was crucial in defining and comprehending the aspects of attachment that children develop toward a primary caregiver and keep throughout their lives. Individuals differ in their attachment categories. Traditionally, attachment categories were categorized as secure or insecure. Individuals who have experienced a secure attachment have an internal working model that allows them to perceive themselves and others positively, whereas those who have experienced an insecure attachment have an internal working model that allows them to perceive themselves and others negatively, which influences their ability to discover their self-efficacy and the world around them [2]. The AAI is a semi-structured clinical interview in which the subject reveals the most important childhood events that currently influencing his adult life [3]. This interview focuses on the adult's state of mind while narrating different childhood events because the interview accentuates how the interviewee speaks about his experience rather than the experience or event itself. The interviewee, for example, can talk comfortably about a difficult previous event during childhood without being moved or invoking those feelings, whereas another may talk differently about the same event as if he is still etched in that stage, whereas yet another may present a kind of dismissing or denying toward these events, by idealizing his parents, or may express some difficulties remembering important acts.
