1. WHAT IS THE "THIRD WAVE"?

1.1 Hayes' Three Waves of Behaviour Therapy

Steven Hayes (2004) proposed a taxonomy of behaviour therapy's evolution:

First Wave — Classical Behaviourism (1950s-1970s). Rooted in Pavlov, Skinner, and Wolpe. Therapy meant modifying observable behaviour through conditioning: systematic desensitisation, token economies, exposure and response prevention. Internal experience was either irrelevant or inaccessible. The therapist was a technician applying learning principles.

Second Wave — Cognitive Revolution (1970s-1990s). Beck, Ellis, and Meichenbaum brought internal cognitions centre stage. Dysfunctional thoughts cause emotional disturbance; therapy means identifying and changing distorted cognitions. Cognitive restructuring, thought records, Socratic questioning, and guided discovery became the core methods. The therapist was a scientist helping the patient test hypotheses.

Third Wave — Contextual and Process-Based Approaches (1990s-present). Rather than changing the content of thoughts, third-wave therapies change the relationship to thoughts. Key features:

• Acceptance over control — emotions and thoughts are not enemies to be eliminated but experiences to be observed and tolerated
• Mindfulness — present-moment, nonjudgmental awareness as a core skill, not just a technique
• Values and meaning — behaviour is guided by personal values, not just symptom reduction
• Therapeutic relationship as active ingredient — not merely the vehicle for delivering techniques but itself a mechanism of change
• Metacognition — stepping back to observe one's own thinking processes rather than engaging with thought content
• Dialectics — holding opposing truths simultaneously; synthesis rather than linear logic
• Contextual sensitivity — behaviour understood in its context, not as inherently "dysfunctional"

2. DIALECTICAL BEHAVIOR THERAPY (DBT)

2.1 The Biosocial Model

DBT explains chronic emotional dysregulation through a transactional model:

Biological vulnerability — three features:

• High emotional sensitivity — emotions triggered easily and by subtle cues
• High emotional reactivity — intense emotional responses once triggered
• Slow return to baseline — emotional arousal persists for hours, not minutes

Invalidating environment — consistently communicates that internal experiences are wrong, inappropriate, or an overreaction. Three types:

1. Punishing or dismissing valid emotional expression ("Stop crying, there's nothing to cry about")
2. Intermittently reinforcing only extreme emotional displays (shapes escalation)
3. Oversimplifying solutions ("Just say no," "Just try harder")

The transaction between biological vulnerability and environmental invalidation produces: emotional dysregulation, self-invalidation, behavioural dysregulation (impulsivity/avoidance), interpersonal dysregulation, and identity confusion.

2.2 Dialectical Philosophy

DBT is grounded in three principles of dialectical philosophy:

1. Interrelatedness — everything is connected; a change in one part of the system affects all other parts
2. Polarity — reality is composed of opposing forces (thesis and antithesis); truth lies in the synthesis
3. Continuous change — the only constant is change; both patient and therapist are always evolving

The fundamental dialectic in DBT: acceptance and change. The patient is doing the best they can AND needs to do better. The therapist validates the patient's suffering AND pushes for new behaviour. Acceptance without change is stagnation. Change without acceptance is invalidation.

2.3 Four Treatment Modes

Mode	Function	Setting
Individual therapy	Motivational; applies skills to specific problems; processes diary card; follows target hierarchy	Weekly, 1 hour
Skills group	Skills acquisition and strengthening; teaching new capabilities	Weekly, 2-2.5 hours
Phone coaching	Skills generalisation to real-life crises; brief, skill-focused calls	As needed, between sessions
Consultation team	Therapy for the therapists; prevents burnout, maintains fidelity; treats therapists' own dialectical dilemmas	Weekly, 1-2 hours

2.4 Target Hierarchy

The target hierarchy governs what is addressed in individual therapy sessions, in strict order:

Stage 1 Individual Therapy Target Hierarchy:

1. Life-threatening behaviours — suicidal ideation, self-harm, homicidal ideation
2. Therapy-interfering behaviours — missed sessions, non-compliance, therapist burnout
3. Quality-of-life-interfering behaviours — substance use, housing instability, eating disorders, interpersonal chaos
4. Increasing behavioural skills — generalising skills from group to daily life

Stage 1 Skills Training Target Hierarchy:

1. Decrease behaviours likely to destroy therapy
2. Increase skills acquisition, strengthening, and generalisation

2.5 Stage Model (Stages 1-4)

Stage	Focus	Goal
Pretreatment	Orientation, assessment, commitment	Informed consent; mutual agreement to proceed
Stage 1	Behavioural stabilisation	Attain basic capacities — safety, control
Stage 2	Emotional processing	Reduce post-traumatic stress; exposure for trauma
Stage 3	Ordinary life problems	Increase self-respect; pursue individual goals
Stage 4	Completeness	Capacity for sustained joy; spiritual fulfilment

2.9 Chain Analysis and Solution Analysis

Chain analysis is a detailed behavioural assessment of the sequence leading to a problem behaviour:

1. Identify the problem behaviour (specific, observable)
2. Identify the prompting event (what set it off)
3. Identify vulnerability factors (what made you susceptible today)
4. Map the chain: event → thought → emotion → body sensation → action urge → behaviour, link by link
5. Identify consequences (reinforcers maintaining the behaviour)

Solution analysis follows immediately:

1. At each link in the chain, identify which skill could have interrupted the sequence
2. Develop a prevention plan for vulnerability factors
3. Commit to specific skill use if the chain begins again

2.10 Diary Card

The diary card is a weekly self-monitoring tool completed daily. It tracks:

• Suicidal urges (0-5 scale)
• Self-harm urges and acts
• Misery (0-5)
• Substance use
• Emotions experienced
• Skills used (checkboxes for each skill)
• Custom targets (personalised)

The diary card is reviewed at the start of every individual therapy session. It determines which targets are addressed according to the target hierarchy.

3. SCHEMA THERAPY (ST)

3.1 The 18 Early Maladaptive Schemas and 5 Domains

Early Maladaptive Schemas (EMSs) are broad, pervasive patterns of memories, emotions, cognitions, and bodily sensations regarding oneself and relationships, developed in childhood when core emotional needs go unmet, and repeated throughout life. Behaviour is NOT part of the schema itself — it is a coping response.

Five core emotional needs:

1. Secure attachment to others
2. Autonomy and competence
3. Freedom to express valid needs and emotions
4. Spontaneity and play
5. Realistic limits and self-control

Full 18 EMSs Table

Domain	#	Schema	Core Belief	Typical Origins
I. Disconnection & Rejection	1	Abandonment/Instability	"People I love will leave me or be unpredictable"	Unstable, unpredictable parent; early loss
2	Mistrust/Abuse	"Others will hurt, exploit, or betray me"	Physical, sexual, emotional abuse; exploitation
3	Emotional Deprivation	"My emotional needs will never be met"	Cold, unaffectionate parents; three subtypes: nurturance, empathy, protection
4	Defectiveness/Shame	"I am fundamentally flawed and unlovable"	Critical, rejecting parents; compared to siblings
5	Social Isolation/Alienation	"I don't belong; I am different from everyone"	Family different from surroundings; not fitting in
II. Impaired Autonomy & Performance	6	Dependence/Incompetence	"I cannot handle life without help"	Overprotective parents who did everything for child
7	Vulnerability to Harm/Illness	"Catastrophe is imminent and I cannot prevent it"	Anxious parent who modelled catastrophising
8	Enmeshment/Undeveloped Self	"I have no identity apart from significant others"	Enmeshed family; parent who lived through child
9	Failure	"I am stupid, inept, and will always fail"	Parents who criticised achievement; unrecognised ADHD
III. Impaired Limits	10	Entitlement/Grandiosity	"I am superior; rules don't apply to me"	Permissive, overindulgent parents; OR overcompensation for deprivation
11	Insufficient Self-Control	"I cannot tolerate frustration or control impulses"	Lack of discipline or structure in childhood
IV. Other-Directedness	12	Subjugation	"I must submit or others will punish/abandon me"	Domineering, controlling parent
13	Self-Sacrifice	"I must meet others' needs at my own expense"	Weak, needy, or ill parent; parentified child
14	Approval-Seeking	"I need others' approval to feel worthy"	Parents valued status over emotional needs
V. Overvigilance & Inhibition	15	Negativity/Pessimism	"Things will go wrong; I must be prepared for the worst"	Pessimistic, worried parent; repeated losses
16	Emotional Inhibition	"I must suppress my emotions to avoid disapproval"	Family discouraged emotional expression
17	Unrelenting Standards	"I must be perfect to avoid criticism"	Parents who set impossibly high standards
18	Punitiveness	"Mistakes deserve harsh punishment"	Punitive, unforgiving parents

3.2 Schema Modes

Modes are moment-to-moment emotional states and coping responses. While schemas are traits, modes are states. Modes are more directly accessible and targetable in session.

Schema Modes Table (Young 2003 — 10 modes)

Category	Mode	Description
Child Modes	Vulnerable Child	Feels abandoned, abused, deprived, helpless, frightened
Angry Child	Enraged about unmet needs; vents without regard for consequences
Impulsive/Undisciplined Child	Acts impulsively; low frustration tolerance
Happy Child	Core needs met; spontaneous, content
Coping Modes	Compliant Surrenderer	Passive, subservient; submits to avoid conflict
Detached Protector	Emotionally withdrawn, numb; may use substances or fantasy
Overcompensator	Counterattacks; appears grandiose, aggressive, or controlling
Parent Modes	Punitive/Critical Parent	Punishes child for expressing needs; harsh self-criticism
Demanding Parent	Sets impossibly high expectations; pressures for perfection
Healthy Mode	Healthy Adult	Nurtures Vulnerable Child, limits Angry/Impulsive Child, battles maladaptive modes

Arntz/Bernstein Expanded Mode Model (18 modes)

Category	Mode	Key Affect/Function
Dysfunctional Child — Vulnerability	Lonely child	Empty, alone, unlovable
Abandoned/abused child	Fear, pain, defencelessness
Humiliated/inferior child	Shame, inferiority
Dependent child	Overwhelmed, regressive
Dysfunctional Child — Anger	Angry child	Frustrated, rebellious
Obstinate child	Passive resistance
Enraged child	Uncontrolled aggression
Dysfunctional Child — Discipline	Impulsive child	Selfish, no delay of gratification
Undisciplined child	Gives up, cannot tolerate boredom
Dysfunctional Parent	Punitive parent	Self-loathing, harsh criticism
Demanding parent	Excessive standards, pressure
Coping — Surrender	Compliant surrender	Passive, subservient, self-deprecating
Coping — Avoidance	Detached protector	Emotional shutdown, dissociation
Avoidant protector	Behavioural avoidance of situations
Angry protector	Wall of anger for distance
Detached self-soother	Addictive soothing/stimulation

Predator	Cold, ruthless elimination of threats
Healthy	Happy child	Core needs met, spontaneous
Healthy adult	Realistic, responsible, balanced

3.3 Three Coping Styles

Coping Style	Threat Response Analogue	Mechanism	Example (Abandonment Schema)
Surrender	Freeze	Gives in to the schema; behaves as if it were true	Selects uncommitted partners and stays
Avoidance	Flight	Avoids triggering situations, emotions, or thoughts	Avoids intimate relationships; drinks when alone
Overcompensation	Fight	Behaves as though the opposite of the schema were true	Clings, smothers; attacks partner for minor separations

3.4 Limited Reparenting

The defining therapeutic relationship model of Schema Therapy. The therapist provides, within appropriate boundaries, what the patient needed but did not receive from parents. This is not becoming a parent — it is a consistent relational stance calibrated to the patient's unmet needs:

• Abandonment → provide stability, consistency, reliability
• Emotional Deprivation → provide warmth, empathy, guidance
• Defectiveness → be accepting, nonjudgmental; welcome flaws
• Subjugation → be non-directive; invite choices
• Entitlement → set limits firmly; hold boundaries

3.5 Core Techniques

Cognitive techniques: Schema validity testing, reframing evidence, coping-style pros/cons, schema flash cards, schema diaries.

Experiential techniques:

• Imagery rescripting — patient accesses childhood memory via affect bridge; helping figure (therapist → third party → patient's healthy adult) enters scene and rescripts the experience. NOT exposure — patient contacts emotion but does not relive full trauma.
• Chair work — two-chair (coping mode exploration) or three-chair (parent mode reduction) dialogues. Therapist initially models Healthy Adult; patient gradually takes over.

Behavioural techniques: Pattern-breaking assignments, social skills training, exposure with response prevention (for coping modes), positive activity scheduling.

3.6 Mode Model for BPD

Four core BPD modes:

1. Abandoned/abused child — intense abandonment fear, helplessness
2. Angry/impulsive child — rage at unfair treatment + impulsive need fulfilment
3. Punitive parent — extreme self-hatred (the signature BPD mode)
4. Detached protector — emotional shutdown, dissociation, substance use

Treatment: 2-3 years, starting at 2x/week. Phase 1 (up to 1 year): work with coping modes, build therapeutic relationship. Phase 2: imagery rescripting for trauma, chair dialogues against punitive parent. Phase 3: transfer healthy adult role, behavioural pattern-breaking.

4. ACCEPTANCE AND COMMITMENT THERAPY (ACT)

4.1 Theoretical Foundation

ACT (pronounced as one word, "act") is rooted in Relational Frame Theory (RFT), a post-Skinnerian account of human language and cognition. RFT proposes that human suffering is largely a product of language: the ability to relate events symbolically means we can re-experience pain through words alone ("remembering" a loss), create suffering about the future ("what if I fail"), and fuse with verbal rules that restrict our behaviour ("I'm not the kind of person who...").

The fundamental problem is not the content of thoughts but our relationship to them. Attempting to control or eliminate unwanted thoughts and feelings (experiential avoidance) is itself the pathological process. ACT targets not symptoms but psychological inflexibility — the rigid dominance of verbal processes over direct experience, leading to behaviour that is incongruent with values.

4.2 Psychological Flexibility and the Hexaflex

The goal of ACT is psychological flexibility: the ability to contact the present moment fully as a conscious human being, and to change or persist in behaviour in the service of chosen values. Six core processes, arranged in a "hexaflex" model, interact to produce flexibility:

Process	Inflexibility Pole	Flexibility Pole	Description
Acceptance	Experiential avoidance	Acceptance	Willingness to have unwanted internal experiences without trying to change, escape, or avoid them
Cognitive Defusion	Cognitive fusion	Defusion	Seeing thoughts as thoughts (mental events) rather than as literal truths; stepping back from thought content
Present Moment	Dominance of past/future	Present-moment awareness	Flexible, voluntary attention to the here-and-now; mindfulness
Self-as-Context	Attachment to conceptualised self	Self-as-context	The observing self — a stable perspective from which to notice changing thoughts, feelings, and roles; "the sky, not the weather"
Values	Lack of values clarity	Values	Chosen life directions that give meaning; not goals but ongoing directions
Committed Action	Inaction/impulsivity/avoidance	Committed action	Concrete behaviours in service of values; includes willingness to fail and try again

4.3 Key Techniques

Creative hopelessness: The therapist helps the patient recognise that all prior attempts to control or eliminate unwanted internal experiences have failed — not because the patient was bad at it, but because the control agenda itself is the problem. This is not nihilism; it creates openness to an alternative approach.

Defusion techniques: "I'm having the thought that I'm worthless" (not "I'm worthless"); thanking your mind for the thought; singing intrusive thoughts to a silly tune; saying the thought slowly until it becomes just sounds; "leaves on a stream" exercise.

Values clarification: Identifying what truly matters across life domains (relationships, work, health, play, spirituality). Values are not goals — they are directions. You never "achieve" a value; you move toward it.

Committed action: Specific, concrete, values-consistent behaviour patterns. Includes exposure exercises, skills building, and goal-setting — similar to traditional CBT behavioural activation but explicitly linked to values rather than mood improvement.

4.4 Evidence Base

Condition	Evidence Level	Key Finding
Chronic pain	Strong (multiple RCTs)	ACT superior to TAU and comparable to CBT; improvements in disability, pain interference
Depression	Moderate (RCTs)	ACT comparable to CBT; mediational analyses support flexibility as mechanism
Anxiety disorders	Moderate (RCTs)	ACT comparable to CBT; especially effective when experiential avoidance is prominent
Psychosis	Emerging (RCTs)	ACT reduces rehospitalisation and distress associated with hallucinations
Substance use	Emerging	ACT shows promise for smoking cessation and polysubstance use
Transdiagnostic	Growing	ACT increasingly used as a transdiagnostic intervention; flexibility is dimension, not diagnosis-specific

5. MINDFULNESS-BASED COGNITIVE THERAPY (MBCT)

5.1 Theoretical Foundation

MBCT was developed by Zindel Segal, Mark Williams, and John Teasdale specifically to prevent relapse in recurrent depression. It is not a general mindfulness programme — it has a precise theoretical rationale.

Differential activation hypothesis (Teasdale, 1988): In remitted depression, low mood can reactivate the specific cognitive patterns (negative automatic thoughts, rumination, hopelessness) that were present during the depressive episode. This reactivation occurs through associative memory networks — the more episodes a person has had, the less mood provocation is required to trigger the full depressive cognitive package. After three or more episodes, relapse can be triggered by normal sadness.

Rumination as mechanism: Rumination (repetitive, self-focused, analytical thinking about causes and consequences of distress) maintains and deepens depressive episodes. MBCT targets rumination not by changing thought content but by changing the mode of processing: from "doing mode" (goal-directed, discrepancy-monitoring, analytical) to "being mode" (present-focused, accepting, experiential).

5.2 The 8-Session Structure

Session	Theme	Key Practices
1	Automatic pilot	Raisin exercise (mindful eating); body scan; recognising autopilot
2	Dealing with barriers	Body scan; thoughts and feelings exercise; identifying wandering mind
3	Mindfulness of the breath	Sitting meditation (breath focus); 3-minute breathing space; seeing/hearing exercise
4	Staying present	Sitting meditation (breath + body); recognising aversion; "thoughts are not facts"
5	Allowing/letting be	Sitting meditation (sounds, thoughts); exploring difficulty; working with aversion
6	Thoughts are not facts	Sitting meditation (choiceless awareness); moods and alternative viewpoints
7	How can I best take care of myself?	Links between activity and mood; nourishing vs. depleting activities; relapse signature; action plan
8	Using what has been learned	Review of course; body scan; maintaining practice; relapse prevention plan

The 3-Minute Breathing Space: The signature MBCT micro-practice, taught from Session 3 and used throughout.

• Minute 1: Awareness — "What is my experience right now?" (thoughts, feelings, body sensations)
• Minute 2: Gathering — Narrow attention to the breath
• Minute 3: Expanding — Expand awareness to the whole body and the present moment

5.3 Evidence Base

Study	Finding
Teasdale et al. (2000)	MBCT reduced relapse by 44% in patients with 3+ prior episodes vs. TAU; no benefit for 1-2 episodes
Ma & Teasdale (2004)	Replicated: MBCT halved relapse risk for 3+ episodes; specific to those with childhood adversity
Kuyken et al. (2008)	MBCT comparable to maintenance antidepressant medication for relapse prevention
Kuyken et al. (2015)	MINDFUL trial (RCT, n=424): MBCT with tapering antidepressants non-inferior to maintenance antidepressants over 24 months
NICE (2009, updated 2022)	MBCT recommended for recurrent depression (3+ episodes) as relapse prevention

6. COMPASSION-FOCUSED THERAPY (CFT)

6.1 Theoretical Foundation

CFT was developed by Paul Gilbert for patients with high shame and self-criticism — particularly those who can generate alternative thoughts cognitively but cannot feel reassured by them. Gilbert's key insight: understanding intellectually that you are not worthless does not reduce shame if the emotional system generating shame is not also addressed.

6.2 Three Emotion Regulation Systems

System	Function	Affect	Neurobiology	Pathology When Dominant
Threat/Protection	Detect and respond to danger	Anxiety, anger, disgust, shame	Amygdala, HPA axis, SNS	Anxiety disorders, PTSD, OCD, shame-based conditions
Drive/Resource-Seeking	Pursue goals, rewards, and resources	Excitement, anticipation, pleasure	Dopamine circuits, nucleus accumbens	Mania, addiction, narcissism, workaholism
Soothing/Affiliation	Calm, connect, feel safe	Contentment, safety, connection	Oxytocin, endorphins, vagal tone	Inadequately developed in high-shame patients

6.3 Compassionate Mind Training

CFT uses specific exercises to activate and strengthen the soothing/affiliation system:

• Compassionate imagery: Creating a detailed image of an ideal compassionate figure (wise, strong, warm, non-judgmental) and practising receiving compassion from this figure
• Compassionate self: Developing an inner compassionate voice — not just correcting distorted thoughts but speaking to oneself with warmth, understanding, and encouragement
• Compassion-focused exposure: Approaching feared situations while deliberately activating the soothing system rather than relying on threat-system coping
• Fears of compassion: Many patients actively resist self-compassion (fear of self-indulgence, grief about unmet needs, belief they do not deserve it). These fears are directly addressed as therapy targets

6. ACT Hexaflex Quick Card

Process	Inflexible Pole	Flexible Pole	In One Sentence
Acceptance	Experiential avoidance	Acceptance	Have unwanted experiences without trying to escape them
Defusion	Cognitive fusion	Defusion	See thoughts as thoughts, not as facts
Present Moment	Past/future dominance	Present awareness	Flexible attention to the here-and-now
Self-as-Context	Conceptualised self	Observing self	"I am the sky, not the weather"
Values	Lack of clarity	Chosen directions	What truly matters across life domains
Committed Action	Inaction/avoidance	Values-consistent action	Concrete behaviours serving values

Two overarching clusters:

• Mindfulness and acceptance: Acceptance + Defusion + Present Moment + Self-as-Context
• Commitment and change: Values + Committed Action

Key ACT techniques: Creative hopelessness, defusion exercises ("I'm having the thought that..."), values clarification, committed action patterns, "leaves on a stream" exercise.

Core distinction from CBT: ACT does not aim to change thought content. It aims to change the relationship to thoughts. Symptom reduction is a byproduct, not a goal.

7. MBCT Session Structure

Session	Theme	Key Practice
1	Automatic pilot	Raisin exercise; body scan
2	Dealing with barriers	Body scan; wandering mind
3	Mindfulness of breath	Sitting meditation; 3-minute breathing space
4	Staying present	Breath + body meditation; "thoughts are not facts"
5	Allowing/letting be	Sounds and thoughts meditation; working with aversion
6	Thoughts are not facts	Choiceless awareness; alternative viewpoints
7	Self-care	Nourishing vs. depleting activities; relapse signature; action plan
8	Maintaining practice	Review; body scan; relapse prevention plan

3-Minute Breathing Space:

• Minute 1: Awareness — "What is my experience right now?"
• Minute 2: Gathering — Narrow to breath
• Minute 3: Expanding — Whole body and present moment

Mechanism: Doing mode (discrepancy monitoring → rumination) → Being mode (present-focused acceptance)

Indication: Relapse prevention for recurrent depression (3+ episodes). NOT for acute depression. No benefit for 1-2 episodes.

10. Viva Questions

Q1. What distinguishes third-wave therapies from second-wave CBT?

Third-wave therapies change the patient's relationship to thoughts rather than the content of thoughts. They emphasise acceptance over control, incorporate mindfulness, attend to values and meaning, use the therapeutic relationship as an active change mechanism, and work at the metacognitive or process level. Second-wave CBT focuses on identifying and modifying distorted cognitions through logical analysis and behavioural experiments.

Q2. Describe the biosocial model in DBT.

Chronic emotional dysregulation arises from a transactional interaction between biological vulnerability (high sensitivity, high reactivity, slow return to baseline) and a pervasively invalidating environment (punishing emotions, reinforcing only extremes, oversimplifying solutions). The model is transactional — the child's sensitivity shapes the environment's response and vice versa, creating escalating cycles. The model is de-shaming: problems are not the patient's fault, but they are their responsibility.

Q3. What is the DBT target hierarchy and why does it matter?

In Stage 1 individual therapy: (1) life-threatening behaviours, (2) therapy-interfering behaviours, (3) quality-of-life-interfering behaviours, (4) increasing skills. The hierarchy is absolute — if suicidal behaviour occurred this week, it is addressed before everything else, regardless of what the patient wants to discuss. This prevents avoidance of lethal risk and ensures systematic progress.

Q4. Name all six DBT validation levels.

(1) Unbiased listening, (2) Accurate reflection, (3) Mind-reading (articulating unspoken experiences), (4) Validation by past history, (5) Validation by current context (the heart of DBT validation — normalising the response), (6) Radical genuineness (treating the person as a capable equal). Level 5 is the most important clinically; Level 6 is the highest and most challenging.

Q5. List the 5 schema domains and give one schema from each.

(1) Disconnection & Rejection — e.g., Abandonment; (2) Impaired Autonomy & Performance — e.g., Dependence/Incompetence; (3) Impaired Limits — e.g., Entitlement; (4) Other-Directedness — e.g., Self-Sacrifice; (5) Overvigilance & Inhibition — e.g., Unrelenting Standards. Distribution: 5-4-2-3-4 schemas per domain.

Q6. Explain the difference between schemas and modes in Schema Therapy.

Schemas are traits — stable, pervasive patterns of memories, emotions, cognitions, and bodily sensations. Modes are states — the moment-to-moment emotional states and coping responses currently active. A patient may have the Abandonment schema as a trait but fluctuate between the Vulnerable Child mode, Detached Protector mode, and Angry Child mode depending on the situation. Modes are more directly accessible in session and more directly targetable.

Q7. What is imagery rescripting and how does it differ from exposure therapy?

In imagery rescripting, the patient accesses a childhood memory via an affect bridge, then a helping figure (therapist, third party, or patient's own healthy adult) enters the scene and changes the outcome — protecting the child, confronting the perpetrator, meeting unmet needs. Unlike exposure therapy, the patient does NOT relive the full trauma. They contact the emotion just enough to activate the memory, then the memory is actively rescripted. Arntz et al. (2007) showed IR was superior to imaginal exposure on guilt, shame, and anger in PTSD.

Q8. Describe the ACT hexaflex and its six processes.

The hexaflex represents six processes that interact to produce psychological flexibility: (1) Acceptance — willingness to have unwanted experiences, (2) Cognitive defusion — seeing thoughts as mental events rather than truths, (3) Present-moment awareness — flexible attention to the here-and-now, (4) Self-as-context — the observing self ("the sky, not the weather"), (5) Values — chosen life directions, (6) Committed action — concrete behaviours serving values. Two clusters: mindfulness/acceptance (processes 1-4) and commitment/change (processes 5-6).

Q9. Why does MBCT only work for patients with 3+ depressive episodes?

MBCT targets the differential activation cascade: in patients with 3+ episodes, mild dysphoria can reactivate the full depressive cognitive package (negative thoughts, rumination, hopelessness) through associative memory networks. After multiple episodes, the threshold for reactivation drops so low that normal sadness triggers relapse. MBCT trains patients to notice early warning signs and shift from "doing mode" (rumination) to "being mode" (acceptance). In patients with 1-2 episodes, relapse is driven more by life events than cognitive reactivation, so the mechanism MBCT targets is not yet established.

Q10. What are the three emotion regulation systems in CFT?

(1) Threat/Protection system — detects and responds to danger; produces anxiety, anger, shame; driven by amygdala and HPA axis. (2) Drive/Resource-seeking system — pursues goals and rewards; produces excitement, anticipation; driven by dopamine. (3) Soothing/Affiliation system — calms and connects; produces contentment, safety; driven by oxytocin and vagal tone. In patients with high shame, the soothing system is underdeveloped while the threat system is overactive. CFT builds the soothing system through compassionate imagery and compassionate mind training.

Q11. Compare the therapeutic relationship across DBT, ST, and ACT.

DBT: dialectical — the therapist balances validation (acceptance) with problem-solving (change); warm but also irreverent; consultation team prevents burnout. ST: limited reparenting — the therapist provides within boundaries what the patient needed from parents (warmth for deprivation, stability for abandonment, limits for entitlement) + empathic confrontation. ACT: the therapist models psychological flexibility; therapist willingness to be present with the patient's pain without trying to fix it; relationship is functional rather than corrective.

Q12. A patient with BPD is being considered for psychotherapy. Compare how DBT and Schema Therapy would each approach the case.

DBT: Biosocial formulation; Stage 1 targets (safety first); individual therapy + skills group + phone coaching + consult team; diary card; chain analysis for self-harm; TIPP for crisis; opposite action for shame; DEAR MAN for interpersonal needs; 1-year commitment. ST: Mode formulation (abandoned child, angry child, punitive parent, detached protector); limited reparenting to build trust (Phase 1, up to 1 year on coping modes); imagery rescripting for childhood trauma (Phase 2); chair work against punitive parent; transfer of healthy adult role (Phase 3); 2-3 years, 2x/week. Key difference: DBT prioritises behavioural stabilisation and skills; ST prioritises emotional processing and schema healing. In practice, DBT skills are often used as a "bridge" in early ST when self-harm or dissociation is present.
