The Adult Attachment Interview (AAI) is a clinical and research tool that offers reliable and valid assessment of adult attachment. It provides information on (1) an adult’s self-protective strategy, i.e., the way the speaker uses information to organise their behaviour when they feel endangered or believe their children to be endangered, (2) a possible set of unresolved traumatic experiences that distort the person’s behaviour without their being aware of it, (3) an over-riding distortion of the strategy such as depression, (4) a pattern of information processing, (5) an interpreted developmental history of the speaker, and, (6) the Level of Parental Reasoning (LPR, Crittenden, Lang, Claussen, & Partridge, 2000), i.e., how the parent thinks about making caregiving decisions for their children. The course offered is based on an expansion of the Bowlby-Ainsworth theory (Crittenden, 1995) and an extension of the Main and Goldwyn procedure (Main & Goldwyn, in press) as applied to the Adult Attachment Interview (George, Kaplan, & Main, 1986, 1996).
The Dynamic Maturational Model (DMM)
approach to the Adult Attachment Interview (AAI) is both a useful
research tool and also a potential guide for professionals working with
psychopathology. Trainees will learn not only new ways to conceptualise
disturbed development, but also ways to identify in adults’ distortions
of the mental processing of information, particularly information
relevant to disorders of feelings, thought, and behaviour. The
techniques for interpreting speech can be useful even if the
professional does not formally use the interview itself in practice. For
those interested in research applications, the 18-day training is
usually sufficient to establish reliability on the major classifications
The Dynamic-Maturational Model (DMM) method (Crittenden, 1999) for analysing Adult Attachment Interviews differs from the Main and Goldwyn method in several ways:
1. Intent: The intent of the Dynamic-Maturational method is to describe the self-protective strategies and patterns of mental processing of speakers; the intent of the Main and Goldwyn method is to predict infants’ patterns of attachment.
2. Outcome classifications: The set of outcome classifications is larger in the Dynamic-Maturational method and better suited to differentiating among individuals with psychological disorder than the set of classifications used by the Main and Goldwyn method.
3. Treatment of non-Ainsworth classifications: The Dynamic-Maturational method uses 6 compulsive Type A sub-patterns (A3-8) and 6 obsessive Type C sub-patterns (C3-8), plus a full array of combinations of these. In the Main and Goldwyn method, most non-normative individuals fall in three classifications (E3, U/E3, and “Cannot Classify”).
4. Patterns vs ratings: The Dynamic-Maturational method depends upon patterns within and among memory systems, whereas the Main and Goldwyn system depends upon ratings of constructs.
5. Functions vs defined meanings: The Dynamic-Maturational method uses the function of discourse markers to define meaning, whereas the Main and Goldwyn method assigns meanings to discourse markers.
6. Memory systems: The Dynamic-Maturational method systematically assesses 5 memory systems (procedural, imaged, semantic, episodic, and working) alongside connotative language, whereas the Main and Goldwyn method considers 3 (semantic, episodic, and working).
7. Modifiers: In the Dynamic-Maturational method, there are four modifiers (depressed, disorientated, reorganising, and unresolved with regard to trauma or loss), with 8 different forms of lack of resolution of trauma or loss (dismissed, displaced, vicarious, blocked, preoccupied, anticipated, imagined, and hinted); the Main and Goldwyn method has only preoccupied lack of resolution of loss or trauma.
8. Validity: Validity for the Main and Goldwyn method is primarily based on normative samples and prediction from mothers to infants, whereas the validity of the Dynamic-Maturational method is primarily based on clinical samples and differentiation among disorders.
The basic training addresses the patterns found in normative and out-patient treatment populations. It involves 18 days of full-time effort coding transcripts. The first 6 days cover most of the Ainsworth-based patterns that form the basis for the Main and Goldwyn system. The second 6 days cover most of the patterns in the dynamic-maturational approach, i.e., A3-6 and C3-6. The third 6 days cover the A/C and AC combinations and some of the modifiers of patterns, e.g., preoccupied and dismissed lack of resolution of trauma and loss, depression, and reorganisation.
Following the basic course members may take a fourth 8-day unit that covers very complex patterning, e.g., A7-8, C7-8, other forms of lack of resolution, disorientation, intrusions of forbidden negative affect, and expressed somatic symptoms. These constructs are relevant to the eating and personality disorders, psychoses, serious (forensic) cases of child protection, some parents of children with psychiatric or psychological disorders, and criminal behaviour.
