Part 1 of this blog Jan. 23 concluded that by 1978, Dr. Mary Ainsworth’s estimate for U.S. babies was that (A) 23% were Avoidant insecure (avoid parents); (B) only 69% were Securely Attached; and (C) 8% were Ambivalent insecure (unhappy and indecisive). [FN1, 11]
By 1988, her Strange Situation study had been done with 2,000 infant-parent pairs in 32 studies in 8 countries. By 1999 it had been done globally with 6,282 infant-parent pairs. Some countries varied, but worldwide results averaged out the same as Ainsworth’s 1978 original. [FN1, 9, 11]
In 1973 Mary Main [above] became Ainsworth’s grad student at Johns Hopkins in Baltimore, working on the Strange Situation experiments from the start. After her doctorate, Main moved to Berkeley, to see if Ainsworth’s Kampala and Baltimore findings would replicate.[FN8] In 1978 she ran a Strange Situation study of 189 Bay Area infant-parent pairs and made the same findings. [FN10]
But by 1979 Dr. Main was making her own discoveries—out of concern about the parents. “In none of Ainsworth’s original observations was the possibility considered that some mothers… could also be frightening,” Main notes. “For my dissertation at Johns Hopkins, I watched 50 children in the Strange Situation… Using Ainsworth’s three-part classification (secure, avoidant and ambivalent), I found at least five infants could not be classified.” Ainsworth was concerned, too; in fact, she’d left some babies in her Secure set only since they didn’t fit her other two sets. [FN8]
By 1982, Main decided to “extend attachment theory to include the import of infant exposure to anomalous fear-arousing parental behaviors… The mother is the haven of safety that must be approached in times of danger. However, when the infant’s biological haven of safety has simultaneously become a source of fright, the infant is placed in an irresolvable and disorganizing approach-flight paradox,” she said. [FN8]
Soon after 1982, Main and Ainsworth agreed that 14-15% of babies actually belong in a new, fourth category: (D) Insecure Disorganized. Their mothers were so frightening that the babies couldn’t develop any consistent response at all. These infants “exhibited a diverse array of inexplicable or overtly conflicted behaviors in the parent’s presence” including “disorganization, disorientation, and confusion.” This includes crying loudly then suddenly freezing; ignoring the parent to rock on hands and knees; moving away; raising hand to mouth in fear; or even swiping at the parent’s face. They seemed vulnerable to dissociation. [FN11, 8]
This finding that a whopping 15% of average U.S. babies are so insecure they’re almost incoherent was so shocking, it was checked for years and not used as a formal 4th category until after 1990 (the delay confused many scholars during 1982-1990). [FN12] But the number held. Worse, among children of American adolescent mothers the rate is over 31%, and is over 25% in many Third World nations. [FN13]
And: to remove the 14-15% of disorganized babies from Ainsworth’s original 69% Secure, reduced the Secure set to only 54-55%. What was up with parents that 45-46% of their kids couldn’t manage secure attachment? If so, Main would have four categories: Avoidant 23%, Ambivalent 8%, Disorganized, 14-15%, Secure 54-55%. [FN1, 11]
By 1982 Main had seen enough to begin developing the Adult Attachment Interview (AAI). She’d seen plenty of disorganized babies – that meant a lot of scary parents. She needed a way to document the behavior of parents. [FN14] (Right: Dr. Main receives the Bowlby-Ainsworth Attachment Award, 2009.)
The AAI was designed to document the level of secure, loving attachment the parents had, during their own childhoods with the babies’ grandparents. Parents were asked “both to described their attachment-related childhood experiences – especially their early relations with parents – and to evaluate the influence of these experiences on their development and current functioning.”
Parents were studied not just on facts they gave, but on how coherent a narrative they could produce quickly. That’s easy for folks who had a secure childhood, but difficult for folks who did not. The AAI questions are designed to “surprise the unconscious” to yield information about the “state of mind with regard to attachment” that might not otherwise show up. Each AAI was taped and transcribed verbatim. Then transcripts were classified by specific patterns by independent trained specialists. [FN15, 10]
In 1983 Main also created the “Berkeley Longitudinal Study” to take the Bay Area infant-parent pairs in her 1978 Strange Situation, and study them for a generation. In 1978, the babies were 12-18 months old; Main and her team re-studied these pairs when the kids reached age 6 in 1983, and studied the kids again when they reached 19 in 1996. [FN8]. In 1983 Main and her team gave three completely different tests to the Bay Area pairs:
— 1. The six year olds were again studied with their parents in the Strange Situation (as in 1978 when they were infants).
— 2. The “sixes” were also individually (without parents) given a new Separation Anxiety Test (SAT): they were shown pictures of children being separated from their parents, then asked how they felt. This was taped, transcribed and sorted by Main’s student Nancy Kaplan into Ainsworth’s three sets: secure, avoidant and ambivalent. [FN16, 8]
— 3. The parents were given the AAI (without their kids). Responses were sorted into three set of adult attachment matching Ainsworth’s three 1978 categories of infant attachment: Secure-autonomous (matching infant Secure), Dismissing (infant Avoidant) and Preoccupied (infant Ambivalent). (Main’s new 4th category wasn’t in use until after 1990.) [FN 17, 8, 10]
Astonishing Results You’ve Never Heard
Dr Main’s first 1983 results were so astonishing that attachment researchers have been buzzing ever since. (Dr. Main and Dr. Erik Hesse, right.) Her results were also so important that it’s outrageous that your doctor never learned this in medical school; your therapist (and mine) never heard of this; you’ve never heard of it; and so you have to read about it here, since the media doesn’t report it. It’s hard to even find this story on the internet; I had to sleuth it out. Her results were:
First: the six year olds’ 1983 responses with parents in the Strange Situation correlated strongly to their 1978 responses in the Strange Situation as infants five years earlier. In 1978 the infants were Securely attached 69%; Avoidant 23%, and Ambivalent 8%. In 1983 the same kids at six were the same as they had been as infants, in the same percents. [FN7]
Second: the six year olds’ 1983 solo responses to the SAT photos also produced the same results and percentages.
Third: The parents’ 1983 solo responses to the Adult Attachment Interview correlated strongly with just how their own kids had behaved as infants, five full years earlier. The parents also turned out to be Secure-autonomous (matching infant “Secure”) 69%; Dismissing (matching infant “Avoidant”) 23%; and Preoccupied (matching infant “Ambivalent”) 8%.
Fourth: The match of the parents’1983 AAI security with how securely their babies behaved five years back in 1978, was at an unheard-of level. It correlated more than 70% of the time, in a field where a 20% correlation is highly significant. “A marked relation between a parent’s discussion of his/her own attachment history (AAI), and the offspring’s Strange Situation behavior 5 years previously, had been uncovered.” [FN8, 10]
Fifth: When the 1978 infants reached age 19 in 1996, they too were given the Adult Attachment Interview. Again results correlated strongly: the 19 year olds’ responses in the AAI in 1996, correlated precisely to their infant behavior in the Strange Situation in 1978, their behavior at six in 1983, and to their parents’ 1983 AAI responses.
That means the Strange Situation predicts an infant’s behavior for life, and the AAI proves it. [FN8, 10]
Sixth: When after 1990 Mary Main’s four categories were used, the results of all the tests were just as strongly correlated across Main’s four categories, as when data were sorted into only three sets. Main’s four categories did become Avoidant 23%, Ambivalent 8%, Disorganized, 14-15%, and Secure 54-55%. Whenever responses to the Strange Situation, SAT, and AAI were sorted into these four sets, the same percents were found. [FN1, 11]
By 2009, over 10,500 subjects globally had been given the AAI and the results continued to average out the same. [FN18]
“Researchers worldwide have replicated the relation originally uncovered in the Bay Area study between a parent’s status in the Adult Attachment Interview and an infant’s Strange Situation response to that same parent… The same average parent-to-child, secure/insecure match of 75% holds even when the interview is conducted before birth of the first child…
“Describing the strength of this relation across studies conducted several years ago, van I Jzendoorn (1995) calculated that it would take 1,087 further attempted replications, every one yielding insignificant results, to reduce the present relation between adult and infant attachment status to insignificance,” Main concluded.

“The three ‘organized’ strategies (secure, avoidant and resistant) are assessed in the Strange Situation (SS), a 20-minute laboratory procedure where patterns of infant behaviour toward the caregiver following two brief separations are categorized… “Infants with secure attachment greet and/or approach the caregiver and may maintain contact but are able to return to play, which occurs in 55% of the general population… Infants with insecure-avoidant attachment fail to greet and/or approach, appear oblivious to their caregiver’s return… avoiding the caregiver, which occurs in 23% of the general population. Infants with insecure-resistant [ambivalent] attachment are extremely distressed by separations and cannot be soothed at reunions, displaying much distress and angry resistance to interactions with the caregiver, which occurs in 8% of the general population.” [This NIH article earlier reports that the remaining “approximately 15% suffer insecure ‘disorganized’ attachment,” citing their own footnote which states “In normal, middle class families, about 15% of infants develop disorganized attachment.” [23%+8%+15% = 46% not securely attached.]

FN5 Earned secure attachment occurs when we experience harmful parenting, so we start with insecure attachment, but find ways to “rise above” childhood trauma and “are now securely attached… What’s more important than what happened to us, is how we’ve made sense of our own childhood,” Dr. Dan Siegel says. “When we make sense of our past… we become free to construct a new future for ourselves and for how we parent our children. Research is clear: If we make sense of our lives, we free ourselves from the prison of the past.” (Source: video by Dr. Mary Main, Dr. Erik Hesse, Dr. Daniel J. Siegel, Dr. Marion Solomon: https://www.youtube.com/watch?v=YJTGbVc7EJY )
The question is: what ways? How do we “rise above” and “make sense” of our childhood trauma?
“Mindfulness has been shown to be effective in healing insecure attachment,” say Siegel’s recent writings. “The purpose of both psychotherapy and mindfulness practice is to provide this internalized secure base. Attunement, whether it is internal in mindfulness, or interpersonal in attachment, is what leads to a sense of secure base.” (The Mindful Therapist: A Clinician’s Guide to Mindsight and Neural Integration, W.W. Norton, 2010; Mindsight: The New Science of Personal Transformation, Random House, 2010).
“The regular exercise of mindful awareness seems to promote the same benefits–bodily and affective self-regulation, attuned communication with others, insight, empathy, and the like–that research has found to be associated with childhood histories of secure attachment,” Siegel wrote earlier. “ Mindfulness and secure attachment alike are capable of generating… the same invaluable psychological resource: an internalized secure base.” (Siegel, 2007, Wallin, 2007, p. 5-6).
In his 1999 book “The Developing Mind: How Relationships and the Brain interact to shape who we are,” (Guilford Press), Siegel defined “earned secure/autonomous attachment” as a pattern noticed by therapists doing the Adult Attachment Interview: “individuals whose experiences of childhood… [were] likely to produce insecure attachment (avoidant, ambivalent, or disorganized),” but their AAI interview responses instead show “a fluidity in their narratives and a flexibility in their reflective capacity, such that their present state of mind with respect to attachment is rated as secure/autonomous. These individuals often appear… to have had a significant emotional relationship with a close friend, romantic partner, or therapist, which allowed them to develop out of insecure…into a secure/autonomous AAI status.”

–Main’s summary of the Strange Situation in this document:
“Ainsworth structured the Strange Situation procedure to include three of Bowlby’s ‘natural clues to danger’ in eight episodes: 1. Introduction to the room. 2. Mother and infant are left alone in a toy-filled environment whose unfamiliarity supplies the first natural clue to danger. However, the mother’s presence is expected to provide the infant with security sufficient for exploration and/or play. 3. Providing a second clue to danger, a stranger joins the mother and infant. 4. The mother leaves the infant with the stranger, providing two combined clues to increased danger. 5. The mother returns, and the stranger departs…. Many infants initially seek proximity but then, reassured of their mothers’ nearness, resume play. 6. The mother leaves, and the infant remains entirely alone in the unfamiliar setting. Infant distress can be strong at this point, and this episode is often terminated rapidly. 7. The stranger, rather than the mother, enters the room. 8. The mother returns… By now, most infants are expected to be crying, and actively not only seeking proximity to mothers, but also… indicating a strong desire to be held… Nonetheless, they are expected to settle and renew interest in exploration and play by the end of this 3-minute period…
“Somewhat surprisingly, Ainsworth found that infant responses to separation and reunion in this procedure fell into three distinct, coherently organized patterns of attachment (“secure,” “insecure-avoidant,” and “insecure-ambivalent” (Ainsworth, Blehar, Waters, & Wall, 1978). … Given the length and complexity of this chapter, we suggest individuals divide reading to its three central parts (secure attachment, pp. 261–273; avoidant attachment, pp. 273–279; and disorganized attachment pp. 279–288).”
