Reference Tool — Not an Assessment

Attachment Styles & Disorders

Purpose: a practical, evidence-informed reference separating attachment theory, attachment patterns, adult attachment dimensions, attachment difficulties, and the two recognised attachment disorders (RAD and DSED).

Important: attachment patterns are not psychiatric diagnoses. School behaviour alone cannot establish an attachment disorder. RAD/DSED require a specific developmental and caregiving history and specialist clinical assessment.

The core idea: attachment is a built-in safety system. Under stress, a child looks for a safe haven — "can I come to you and become settled?" — and once safety is restored, a secure base — "can I move away, learn and explore while trusting you remain available?" How a child answers those two questions, especially under stress, is what the patterns below describe.

Secure

"I can need you without losing myself."

Reference tool — informs practice, does not diagnose or label.

iWhat it is

Core strategy: Uses the relationship flexibly. Internal expectation: "When I need you, you will probably help; once I am settled I can get on with things."
Help seeking: Can seek support when needed without needing to remain permanently dependent.
Comfort: Usually able to accept appropriate reassurance and use the relationship to settle.
Exploration: Can move away from the attachment figure and engage in learning, play, peers, novelty, and independent activity when sufficiently safe.
Separation/reunion: May show distress at separation, but reunion generally helps regulate and restore engagement.
Rupture/repair: Can tolerate ordinary relational friction and reconnect after correction, conflict, or disappointment.
Developmental direction: Repeated co-regulation gradually contributes to greater self-regulation and flexible independence.

@What it can look like at school

Teacher correctionBrief upset; accepts repair; returns to task.

Adult offers helpUses it if needed.

Trusted staff absentAdjusts with information/support.

Relationship conflictCan tolerate rupture and reconnect.

Adult attention elsewhereUsually tolerates ordinary divided attention.

Emotional vulnerabilityCan disclose and accept support.

✓What helps — keep doing this

Turn up when expected — predictability reduces the need to monitor whether support will be available.
Keep mood relatively stable and readable.
Set limits without humiliation.
Don't withdraw warmth after behaviour — conflict doesn't have to equal abandonment.
Tolerate anger without retaliating; follow through; repair after rupture.
Return the student to independence rather than becoming a permanent regulator.

!Keep in mind

Secure does not mean: obedient, never anxious, never dysregulated, always affectionate, always independent, or raised in a perfect family.

Avoidant

"Needing you does not feel reliably useful, so I turn the signal down."

Reference tool — informs practice, does not diagnose or label.

iWhat it is

Comfort seeking: Does not readily seek comfort; turns away; rejects offers of help — visible dependency may have been ineffective, uncomfortable, or discouraged, so the child minimises attachment signalling.
Presentation: Appears unusually self-contained, independent, indifferent, or "fine" after distress. Low visible distress does not automatically equal low internal activation.
Emotion: Minimises hurt, shuts down discussion, becomes irritated by nurturing language, says "I don't care" or "leave me alone" — deactivation reduces the interpersonal exposure of needing someone.
Rupture: May withdraw, cut the adult off, act indifferent, or avoid repair — distance is used to regain control and reduce dependency.
School risk: Adults may conclude "he does not care" or "she does not need support" — the behaviour may reflect reduced signalling rather than absence of need.

@What it can look like at school

Teacher correction"Don't care"; disengages; distances from adult.

Adult offers helpRejects or minimises need.

Trusted staff absentMay look indifferent or become more self-contained.

Relationship conflictWithdraws, cuts adult off, acts unaffected.

Adult attention elsewhereMay detach further or pretend not to care.

Emotional vulnerabilityMinimises, conceals, changes topic or becomes irritable.

✓What helps

Don't withdraw the relationship after behaviour — let conflict be survivable without demanding a display of need.
Notice distress without invading; offer access without forcing emotional exposure.
Follow through and stay predictable — the offer of help stays open even when it's turned down.
Tolerate the "I don't care" without escalating; respect the self-reliance while leaving the door open.
Watch for help sought indirectly or only after escalation, rather than assuming no need exists.

!Keep in mind

Do not diagnose from behaviour: a student saying "fuck off, I do not need help" could be using an avoidant/deactivating strategy — or could be angry, embarrassed, autistic, anxious, traumatised, oppositional, protecting status, or simply responding to an adult they dislike.

Resistant / Ambivalent

"I cannot be sure you will remain available, so I need to keep the signal strong."

Reference tool — informs practice, does not diagnose or label.

iWhat it is

Reassurance: Repeated checking — "Are you angry?", "Do you still like me?", "Are you here tomorrow?" The signal stays high because adult availability isn't experienced as predictable enough.
Separation: High distress when an important adult leaves or becomes unavailable — maintaining proximity becomes a high-priority safety strategy.
Comfort: Seeks the adult but may not settle easily once available — the problem isn't gaining contact, it's uncertainty about whether it will continue.
Attention: Strong sensitivity to the adult helping somebody else; jealousy or repeated bids for attention.
Conflict: Can combine clinging, anger, protest and persistent attempts to repair — the signal is amplified, not deactivated.

@What it can look like at school

Teacher correctionRepeated checking: "Are you angry?"; pursues repair/reassurance.

Adult offers helpMay seek excessive involvement and have difficulty ending support.

Trusted staff absentHigh checking/distress; seeks substitute proximity or certainty about return.

Relationship conflictPursues reassurance, repair and confirmation.

Adult attention elsewhereCompetes for attention; monitors adult closely.

Emotional vulnerabilityMay intensify disclosure/reassurance needs.

✓What helps

Turn up when expected — predictability does more here than any single reassurance.
Follow through on what you say, every time; broken small promises cost more than they look like.
Keep mood relatively stable and readable, so the student isn't working to read which version of you has arrived.
Expect that reassurance may need repeating — it can settle the moment without settling the underlying uncertainty.

!Keep in mind

Core idea: reassurance may work briefly but fail to terminate the worry. The child may need another "dose" because availability still feels uncertain.

Disorganised

"I need safety from you, but approaching you does not reliably resolve the alarm."

Reference tool — informs practice, does not diagnose or label.

iWhat it is

Core pattern: Conflicted, contradictory, apprehensive, disoriented, or disrupted attachment behaviour when the attachment system is strongly activated.
May include: Approach followed by freezing, approach while averting, abrupt changes in direction, apprehension toward the caregiver, contradictory proximity-seeking and avoidance, or momentary disorientation.
Conceptually: The usual solution to alarm — approach the attachment figure — may itself become entangled with alarm, fear, helplessness, or unresolved threat.

?Potential contributors

Frightening or frightened caregiving: Can contribute, but is not the only pathway.
Maltreatment / severe unpredictability: Associated with elevated risk, but disorganisation is not proof that maltreatment occurred.
Caregiver dissociation or frightening behaviour: The caregiver can be both a source of potential comfort and alarm.
Domestic violence / frightening family context: May affect the attachment relationship directly or indirectly.
Fear for the caregiver: The child can become alarmed by perceived threat to the caregiver, not only from the caregiver.

@What it can look like at school

Teacher correctionApproach/attack/freeze/withdraw may appear contradictory or hard to organise.

Adult offers helpWants support but may react strongly, freeze, avoid, or reverse course when it arrives.

Trusted staff absentBehaviour may destabilise sharply or become contradictory.

Relationship conflictMay combine proximity seeking, hostility, avoidance, freezing or disorientation.

Adult attention elsewhereResponse can be highly variable/conflicted.

Emotional vulnerabilityMay become fragmented, contradictory or suddenly dysregulated.

✓What helps

Prioritise predictability and non-frightening consistency above all else.
Keep your own emotional regulation steady — a dysregulated adult response can add to the entanglement rather than resolve it.
Repair deliberately after any rupture rather than assuming it will settle on its own.
Expect the response to look contradictory in the moment; that unpredictability is the pattern, not a sign you're doing something wrong.

!Keep in mind

Forensic warning: disorganised attachment cannot be treated as a diagnostic test for abuse or neglect. It does not establish why the pattern developed. It is not "the worst attachment style," proof of abuse, the same thing as RAD, a permanent personality type, or a conclusion you can draw from ordinary school behaviour without a formal assessment.

Reactive Attachment Disorder (RAD)

Something substantially more severe happened to selective attachment development, under conditions of extreme insufficient caregiving.

Reference tool — informs practice, does not diagnose or label.

iWhat it is

Core attachment behaviour: A consistent pattern of inhibited, emotionally withdrawn behaviour toward adult caregivers. The child rarely or minimally seeks comfort when distressed and rarely or minimally responds to comfort.
Social/emotional disturbance: May include minimal social/emotional responsiveness, limited positive affect, or episodes of unexplained irritability, sadness or fearfulness evident during non-threatening caregiver interactions.
Care history: A pattern of extreme insufficient care must be established and judged capable of accounting for the disturbance.
Developmental requirements: Developmental age of at least about 9 months; the disturbance must be evident before age 5.
Clinical meaning: A severe disturbance of selective attachment behaviour — not ordinary emotional withdrawal or an avoidant attachment strategy.

?What can cause it

Required etiological context: Extreme insufficient care / severe social neglect or deprivation, repeated changes of primary caregiver, or rearing contexts that severely limit selective attachment opportunities.

Feature	Avoidant attachment	RAD
Type	Classification / strategy	Psychiatric disorder
Comfort seeking	May minimise, delay or reject comfort	Rarely or minimally seeks comfort
Severe neglect required?	No	Yes — extreme insufficient care required
Prevalence	An insecure pattern; far more common	Uncommon and substantially more severe

✓What helps

Create or preserve stable, consistent caregiving relationships wherever possible.
Improve noticing and accurate interpretation of the child's cues rather than responding only to surface behaviour.
Reduce threatening, humiliating, unpredictable, coercive or dysregulated adult behaviour.
For older children/adolescents, integrate trauma treatment, emotion regulation, caregiver relationships, peer functioning, and school supports alongside any co-occurring conditions.
Refer for a full developmental, caregiving and clinical differential assessment — see how attachment is assessed.

!Keep in mind

Diagnostic gate: without the required history of extreme insufficient care, difficult relationships or social behaviour alone do not justify RAD/DSED.

Disinhibited Social Engagement Disorder (DSED)

Developmentally inappropriate, overly familiar behaviour toward unfamiliar adults — requires the same extreme-insufficient-care history as RAD.

Reference tool — informs practice, does not diagnose or label.

iWhat it is

Core social behaviour: A pattern of actively approaching and interacting with unfamiliar adults in a developmentally inappropriate, insufficiently selective way.
Possible manifestations: Reduced/absent reticence approaching unfamiliar adults; overly familiar verbal or physical behaviour; reduced checking back with the caregiver after venturing away; willingness to go off with an unfamiliar adult with little/no hesitation.
Not simply sociability: Being friendly, extroverted or comfortable with adults is not enough — the behaviour is developmentally inappropriate and boundary/selectivity is impaired.
Not simply ADHD: Social disinhibition must not be limited to impulsivity — the specific social pattern matters.
Clinical risk: Weak stranger boundaries and limited social selectivity can create significant safety and relational problems.

Situation	ADHD-consistent hypothesis	DSED-consistent hypothesis
Rapidly approaches a new adult	Novelty seeking + impulsive approach	Reduced normal reticence toward unfamiliar adults
Talks excessively, over-familiar	Impulsivity, poor turn-taking	Developmentally inappropriate familiarity, specifically with unfamiliar adults
Wanders / follows an adult	Distractibility may explain unsafe movement	Reduced checking-back; willing to leave with a stranger

Comorbidity is possible — the distinction matters more, not less, when both could be present.

✓What helps

Same caregiving-stability and non-frightening-caregiving principles as RAD — see treatment principles.
Plan around the clinical safety risk directly: weak stranger boundaries need active supervision, not just correction.
Rule out ADHD via a full cross-setting executive-function assessment before assuming DSED.
Refer for the same developmental + caregiving history work-up required for RAD.

!Keep in mind

Diagnostic gate: without the required history of extreme insufficient care, difficult relationships or social behaviour alone do not justify RAD/DSED.

Adult attachment: dimensions rather than boxes

Better read as two continuous dimensions — anxiety and avoidance — than four rigid personality boxes.

Reference tool — informs practice, does not diagnose or label.

iThe two dimensions

Dimension	Central concern	Higher levels often involve
Attachment anxiety	"Will you still be there for me?"	Fear of rejection/abandonment; monitoring relationship cues; reassurance seeking; hyperactivation when the relationship feels threatened.
Attachment avoidance	"Is relying on you safe or useful?"	Discomfort with dependency and vulnerability; emotional distancing; self-reliance; suppression/deactivation of attachment needs.

Combination	Shorthand label	Typical tendency
Low anxiety + low avoidance	Secure	Comfortable with closeness and autonomy.
High anxiety + low avoidance	Anxious / preoccupied	Strong proximity/reassurance seeking; hyperactivation.
Low anxiety + high avoidance	Dismissive-avoidant	Strong self-reliance; deactivation.
High anxiety + high avoidance	Fearful-avoidant	Wants closeness but expects danger/rejection; may oscillate.

iSelf-report vs the Adult Attachment Interview

Romantic/relationship self-report measures current anxiety/avoidance tendencies (secure, anxious/preoccupied, dismissive-avoidant, fearful-avoidant). The Adult Attachment Interview (AAI) instead evaluates an adult's state of mind through the coherence and organisation of discourse about attachment experiences (secure/autonomous, dismissing, preoccupied, unresolved/disorganised). Note: the source document's text describing exactly how these two systems differ was truncated at the page edge — the categories are not simply interchangeable between the two methods.

Common internet error: "Fearful-avoidant = adult disorganised attachment" is an oversimplification. Different methods operationalise different constructs.

iInsecurity is not a psychiatric disorder

Insecure attachment is common enough to be a normal variation in relationship organisation	Can be associated with increased vulnerability but is not itself a DSM diagnosis.
Attachment anxiety/avoidance can be high without mental disorder	A person may show strong tendencies without meeting criteria for any psychiatric condition.
Insecurity is statistically associated with some mental-health difficulties	Association ≠ insecurity causes every symptom, or psychiatric symptoms prove insecurity.
Clinical diagnosis requires disorder-specific criteria	Don't translate a descriptive attachment label directly into a psychiatric diagnosis.

Is it something else?

Why "attachment issues" is not enough on its own.

Reference tool — informs practice, does not diagnose or label.

Possible explanation	Why it can resemble attachment difficulty	What needs separating out
ADHD	Impulsivity, poor inhibition, intense social approach, emotional lability, repeated reassurance, conflict with adults.	Executive-function/impulsivity pattern vs relationship-specific safety/proximity organisation.
Autism	Differences in social reciprocity, eye contact, comfort-seeking expression, rigidity, sensory responses, social approach or withdrawal.	Neurodevelopmental social-communication/sensory profile vs attachment behaviour.
PTSD / trauma	Avoidance, hypervigilance, emotional numbing, dysregulation, mistrust, threat sensitivity.	Trauma symptom clusters and triggers vs organisation of attachment relationships.
Anxiety disorders	Clinginess, reassurance seeking, school refusal, separation concerns, checking.	Specific anxiety mechanisms vs attachment strategy.
Depression	Withdrawal, low positive affect, reduced social engagement, irritability.	Mood syndrome/course vs attachment disturbance.
Language / communication disorder	Difficulty expressing need, misunderstanding social cues, frustration around help.	Communication capacity vs unwillingness/inability to use attachment figure.
Intellectual / developmental disability	Immature social behaviour, dependency, poor stranger awareness, regulation difficulties.	Developmental level and adaptive function.
Conduct / oppositional patterns	Conflict, rejection of adults, control battles, hostility.	Reinforcement, coercive cycles, values, peer/status and behavioural functions vs attachment-specific mechanisms.
Placement/caregiver instability	Can create real relational disruption and mistrust.	Whether disorder criteria are met versus understandable adaptation to instability.

How attachment is assessed

Assessment

Reference tool — informs practice, does not diagnose or label.

Method / source	Typical use	What it can contribute
Strange Situation Procedure	Infant/toddler research/assessment under standardised separation-reunion conditions.	Classification of attachment behaviour in a specific caregiver relationship.
Attachment Q-Sort	Observation-based, often naturalistic.	Degree of secure-base behaviour across a broader behavioural sample.
Story-stem / narrative approaches	Children able to represent relationship scenarios symbolically.	Representations and expectations around attachment themes.
Child Attachment Interview	Middle childhood/adolescent, specialist/research contexts.	Attachment representations/state of mind.
Adult Attachment Interview	Adult state of mind regarding attachment.	Coherence/organisation of discourse about attachment experiences.
Developmental + caregiving history	Essential for suspected RAD/DSED.	Establishes severe neglect/deprivation, caregiver changes, institutional care, timing and developmental context.
Direct caregiver-child observation	Important in clinical evaluation.	How comfort seeking, response to comfort, selectivity, reciprocity and regulation function in vivo.
Cross-setting information	School, home, placement, childcare, clinicians.	Determines pervasiveness, context sensitivity and competing explanations.

iA RAD/DSED work-up should include

Developmental history — clarifies developmental level, onset and broader neurodevelopmental factors.
Caregiving / placement history — required to establish the etiological context.
Trauma and neglect history — documents severity, timing and nature of adverse caregiving.
Observation of the child-caregiver relationship — comfort seeking, comfort response, selectivity, regulation.
Social behaviour across settings — distinguishes a pervasive disorder from context-specific behaviour.
Autism / ADHD / developmental differential — prevents misattribution.
Mental-health differential — PTSD, anxiety, depression and other relevant syndromes.

Treatment & intervention principles

The goal is not to "make the child attach" — it's a safer, more usable caregiving relationship that lets attachment behaviour reorganise over time.

Reference tool — informs practice, does not diagnose or label.

Target	Evidence-informed direction
Caregiving stability	Create or preserve stable, consistent caregiving relationships wherever possible.
Caregiver sensitivity	Improve noticing and accurate interpretation of child cues rather than responding only to surface behaviour.
Responsiveness	Increase timely, developmentally appropriate responses to distress and bids for connection.
Non-frightening caregiving	Reduce threatening, humiliating, unpredictable, coercive or dysregulated adult behaviour.
Caregiver emotional regulation	Support adults to stay regulated enough to co-regulate the child and avoid escalating relational threat.
Positive behaviour management	Predictable boundaries and reinforcement, without treating attachment as an excuse to avoid expectations.
Relationship repair	Help conflict be followed by reconnection rather than permanent rupture.
Video-feedback interventions	Structured review of real caregiver-child interactions to build cue-noticing and responsiveness.
Older children / adolescents	Integrate trauma treatment, emotion regulation, caregiver relationships, peer functioning, school supports and co-occurring conditions.

Coercive "attachment therapy" warning

Safety warning

Reference tool — informs practice, does not diagnose or label.

Unsafe / unsupported practice	Why it is a problem
Forced holding / restraint intended to create attachment	Coercion does not establish safety and can intensify fear, helplessness and trauma.
"Rebirthing" techniques	No credible scientific basis; historically associated with severe harm and deaths.
Food / water manipulation to force dependency	Abusive, medically dangerous and conceptually inconsistent with secure caregiving.
Deliberately escalating distress so the child "breaks through"	Confuses submission/exhaustion with attachment and regulation.
Forcing eye contact, affection or emotional disclosure	Can violate autonomy and reinforce the idea that adults control access to safety.

Professional position: AACAP opposes coercive interventions marketed for attachment disorders. Evidence-based care focuses on stable, responsive, non-frightening caregiving — not forcing dependency.

Attachment vs trauma

Comparison

Reference tool — informs practice, does not diagnose or label.

Attachment	Trauma
Main question: "How is safety organised in important relationships?"	Main question: "What has the threat system learned from overwhelming or dangerous experience?"
Proximity, comfort, selective relationships, safe haven, secure base, separation, reunion, rupture, repair.	Threat memory, intrusion, avoidance, hyperarousal, negative beliefs/mood, dissociation, trauma-linked triggers.
Can be secure or insecure with or without a trauma disorder.	A person can meet criteria for PTSD while having secure attachment relationships.
Insecurity can occur without maltreatment or trauma.	Trauma can occur outside attachment relationships.
RAD/DSED require severe insufficient care; ordinary insecurity does not.	Trauma history alone does not establish RAD/DSED.

Avoid the blob: "Trauma/attachment" is often used as if it were one diagnosis. Keeping the constructs separate makes assessment and intervention more precise.

Attachment vs personality disorders

Comparison

Reference tool — informs practice, does not diagnose or label.

Internet shortcut	Why it is wrong
"Anxious attachment = borderline personality disorder"	Attachment anxiety is a relationship dimension. BPD is a clinical diagnosis requiring a broader enduring pattern of impairment and specific diagnostic criteria.
"Avoidant attachment = avoidant personality disorder"	Attachment avoidance concerns dependency/closeness regulation; avoidant personality disorder involves pervasive social inhibition, inadequacy and hypersensitivity to negative evaluation.
"Dismissive attachment = narcissism"	Self-reliance or emotional distancing does not establish narcissistic personality disorder.
"Disorganised attachment becomes a personality disorder"	Attachment insecurity can be one vulnerability factor among many; developmental outcomes are probabilistic and multifactorial.

Reading the room

Instead of asking "which attachment style does this student have?", watch what happens to relationship behaviour under stress.

Reference tool — informs practice, does not diagnose or label.

?Questions to ask yourself

Proximity: Under stress, do they move toward adults, away from adults, oscillate between both, or appear frozen/conflicted?
Help seeking: Can they ask directly? Do they refuse help? Do they create situations that force engagement? Do they seek help only after escalation?
Reassurance: Does reassurance settle the concern, or does it need to be repeated continuously?
Adult availability: What happens when the preferred adult works with somebody else, leaves the room, is absent, or changes routine?
Separation / transition: What happens at drop-off, transitions, relief staff, end of day, end of term, staff rotation or change of class?
Rupture / repair: What follows correction, a limit, perceived rejection, disappointment, or conflict — and can the student reconnect?
Dependency: Can the student tolerate needing help, or does dependency trigger shame, anger, avoidance or control?
Uncertainty / control: How do they respond when they can't read the adult's mood or intentions? Does interpersonal control increase when felt safety decreases?

✓Being a safety figure — what matters

Turn up when expected — predictability reduces the need to constantly monitor availability.
Keep mood relatively stable and readable.
Set limits without humiliation, and don't withdraw warmth after behaviour.
Tolerate anger without retaliating; follow through; notice distress without invading.
Return the student to independence rather than becoming a permanent regulator; repair after rupture.

iPrediction and the "vibe" a student gets

Past interactions shape what a student expects an adult to do next — the same words can land completely differently depending on that history. When you say "come over here, I want to help," the internal prediction might be "good — help," or it might be "I'm about to get embarrassed," "they're going to make me talk about feelings," "something bad is coming," "I'll owe them or lose control," or "finally — but now I need to make sure they don't leave."

Practical link: students read far more than literal words — voice, face, posture, proximity, timing, predictability, confidence, warmth, demand load and the adult's emotional state all shape the prediction of "what happens next."

!The self-reinforcing loop

A student's underlying need (connection, predictability, acceptance, safety) can lead to a protective strategy (insulting the adult, rejecting help, controlling the interaction, escalating reassurance-seeking, withdrawing). If the adult reacts by becoming defensive, punitive, avoidant or withdrawing contact, the student learns "adults leave/reject/humiliate/can't be trusted when I need them" — and approaches the next situation with even more of the same strategy.

Better language than "testing adults": the child's protective strategy may inadvertently create conditions that confirm the relationship prediction they already hold. This does not require conscious testing.

The big picture

Foundations

Reference tool — informs practice, does not diagnose or label.

iDo not mash these terms together

Term	Status	What it does NOT mean
Attachment pattern / classification	Research/developmental construct	A psychiatric diagnosis or a permanent personality type.
Adult attachment anxiety / avoidance	Dimensional relationship constructs	A personality disorder diagnosis.
Attachment difficulties	Broad descriptive term	Automatically RAD, DSED, abuse, or disorganised attachment.
RAD	Psychiatric disorder	The same as avoidant attachment.
DSED	Psychiatric disorder	The same as being outgoing, impulsive, or anxiously attached.

Bottom line: avoidant attachment, disorganised attachment, RAD and DSED are not points on one severity scale. They are different constructs.

iPatterns are not destiny

Attachment shows continuity but also meaningful change — relationships, environments, developmental capacities, stressors and new attachment figures can alter the pattern.
Longitudinal pathways are probabilistic, not deterministic.
Disorganisation can shift toward organised patterns as caregiving conditions improve.
Attachment is relational — expectations are learned and repeatedly updated through actual relational experience.

iWhat shapes attachment?

Influence	What the evidence suggests
Caregiver sensitivity / responsiveness	Availability, accurate cue-reading, non-frightening responses and effective co-regulation matter.
Child temperament	Can influence how behaviour is expressed, but associations with classification are generally modest.
Stress and adversity	Poverty, caregiver stress, illness, violence, instability and trauma can alter caregiving conditions and relational predictability.
Multiple caregivers / attachment network	Children can develop different patterns in different relationships; one supportive relationship can matter.
Intergenerational experience	Parents' own histories can influence caregiving, but transmission isn't automatic or deterministic.

iThe clean hierarchy

Level	Meaning	Examples
1. Attachment system	Human safety/proximity regulation system.	Activation under threat; safe haven; secure base.
2. Attachment relationship	The actual attachment bond with a particular caregiver.	Child-mother, child-father, child-foster carer.
3. Attachment pattern	How attachment behaviour is organised in that relationship.	Secure, avoidant, resistant/ambivalent, disorganised.
4. Attachment difficulties	Broad descriptive relationship/regulation difficulties.	Mistrust, high reassurance, withdrawal, rupture/repair problems.
5. Attachment disorders	Specific psychiatric diagnoses.	RAD and DSED only.

iFive-line memory model

Secure: "I can need you without losing myself."
Avoidant: "Needing you does not feel reliably useful, so I turn the signal down."
Anxious / resistant: "I cannot trust your availability, so I turn the signal up."
Disorganised: "I need safety from the relationship, but the relationship itself is tangled up with alarm."
RAD / DSED: "Something substantially more severe happened to selective attachment development under conditions of extreme insufficient caregiving."

Practice guardrails for schools and support staff

Practice guardrails

Reference tool — informs practice, does not diagnose or label.

Do	Do not
Describe observable behaviour: "seeks repeated reassurance after correction and struggles to return to task."	Write "has attachment issues" as though it explains the behaviour.
Track context: stressor, adult, separation, rupture, repair, help seeking, attention shift, transition.	Infer childhood abuse from disorganised-looking behaviour.
Use attachment language as a hypothesis about regulation and relationship prediction.	Diagnose RAD/DSED from classroom behaviour.
Consider neurodevelopment, trauma, anxiety, communication, learning history, sensory factors, demand load and relationship quality.	Treat attachment as the only explanatory framework.
Increase predictability, reliable follow-through, non-humiliating boundaries and repair.	Remove all boundaries in the name of "connection before correction."
Refer for appropriate clinical assessment when there is genuine concern about attachment disorder or severe neglect history.	Use online attachment quizzes or informal labels as diagnostic evidence.
