The ACT "hexaflex" describes six core psychological processes that ACT aims to cultivate. What are they?

A: Acceptance, Defusion, Contact with the present moment, Self-as-context, Values, and Committed action

B: Mindfulness, Acceptance, Compassion, Defusion, Emotion regulation, and Values clarification

C: Distress tolerance, Emotion regulation, Mindfulness, Interpersonal effectiveness, Acceptance, and Commitment

D: Validation, Commitment, Flexibility, Acceptance, Compassion, and Exposure

Correct: Acceptance, Defusion, Contact with the present moment, Self-as-context, Values, and Committed action

The ACT hexaflex (Hayes et al., 1999) names six interrelated psychological processes targeted in ACT: (1) Acceptance — willingness to have difficult thoughts and feelings without fighting them; (2) Cognitive defusion — creating distance from thoughts, seeing them as mental events rather than truths; (3) Contact with the present moment — mindful attention to the here-and-now rather than past or future; (4) Self-as-context (the observing self) — experiencing oneself as the stable context that contains thoughts and feelings, not as those contents; (5) Values — clarifying what matters most to the person; (6) Committed action — taking values-consistent action even in the presence of difficult private events. Together these six processes promote "psychological flexibility" — the ability to behave effectively in the service of values regardless of internal states.

ACT proposes that many psychological problems arise from "psychological inflexibility." What is the ACT concept of "experiential avoidance" and how does it maintain psychological problems?

A: Experiential avoidance is the tendency to avoid external feared situations; it maintains anxiety by preventing extinction learning

B: Experiential avoidance is the attempt to suppress, avoid, or escape from unwanted private experiences (thoughts, feelings, memories, bodily sensations) — which paradoxically increases their frequency, salience, and behavioural control, narrowing the person's life as more and more is avoided

C: Experiential avoidance is the use of CBT techniques to avoid engaging with emotional material, maintaining a cognitive rather than experiential therapy stance

D: Experiential avoidance refers to the avoidance of new experiences in general, driven by anxiety about the unknown

Correct: Experiential avoidance is the attempt to suppress, avoid, or escape from unwanted private experiences (thoughts, feelings, memories, bodily sensations) — which paradoxically increases their frequency, salience, and behavioural control, narrowing the person's life as more and more is avoided

Experiential avoidance is one of ACT's core concepts: the attempt to alter the form, frequency, or context of private events (thoughts, feelings, sensations, memories, urges) even when doing so causes harm. The problem is that attempted suppression tends to increase the intrusiveness of the avoided experience (ironic rebound effects, as demonstrated by Wegner's "don't think of a white bear" studies), and that organising behaviour around avoidance of internal states progressively narrows life — the person gives up more and more valued activities to avoid difficult feelings. ACT aims to replace experiential avoidance with acceptance (willingness to have these experiences) and values-based committed action.

DBT for borderline personality disorder has four core skills modules. What are they and what function does each serve?

A: Mindfulness (awareness), Distress tolerance (survival skills), Emotion regulation (changing emotions), Interpersonal effectiveness (relationship skills)

B: Acceptance (of self), Commitment (to change), Validation (from others), Exposure (to avoided emotions)

C: Cognitive restructuring, Behavioural activation, Thought records, Problem-solving

D: Schema awareness, Mode work, Reparenting, Chair work

Correct: Mindfulness (awareness), Distress tolerance (survival skills), Emotion regulation (changing emotions), Interpersonal effectiveness (relationship skills)

DBT's four skills modules are: (1) Core mindfulness — the foundation of all DBT; skills for observing, describing, and participating in the present moment without judgment; the "wise mind" synthesis of rational and emotional mind; (2) Distress tolerance — crisis survival skills (TIPP, ACCEPTS, self-soothe, IMPROVE) for enduring acute emotional crises without making things worse; radical acceptance; (3) Emotion regulation — understanding emotions, reducing vulnerability, increasing positive emotions, changing emotions through opposite action; (4) Interpersonal effectiveness — skills for maintaining relationships while asserting needs and preserving self-respect (DEAR MAN, GIVE, FAST). DBT combines individual therapy, group skills training, phone coaching, and therapist consultation team.

DBT was specifically designed for borderline personality disorder (BPD). Which Linehan theory explains why standard CBT was often experienced as invalidating by people with BPD?

A: Social learning theory — people with BPD modelled their therapist's critical stance

B: Biosocial theory — BPD arises from a biologically based emotional sensitivity transacting with an invalidating environment in development; standard CBT's focus on change was experienced as another invalidating message

C: Schema theory — BPD is driven by early maladaptive schemas that CBT cannot access

D: Attachment theory — BPD reflects disorganised attachment that CBT does not address

Correct: Biosocial theory — BPD arises from a biologically based emotional sensitivity transacting with an invalidating environment in development; standard CBT's focus on change was experienced as another invalidating message

Linehan's biosocial theory proposes that BPD results from the transaction between biological emotional sensitivity (high reactivity, slow return to baseline) and a pervasively invalidating environment (caregivers or culture that communicated that the person's emotional responses were wrong, bad, or excessive). When people with BPD encountered standard CBT — which focuses on identifying and changing "distorted" thoughts and "dysfunctional" behaviours — the change-focused message felt like another instance of being told their responses were wrong. DBT was designed to balance validation (communicating that the client's responses make sense given their history and biology) with change (pushing for new skills and behaviours), resolving this dialectical tension.

Mindfulness-Based Cognitive Therapy (MBCT) was developed primarily for which clinical population and what was the key finding that motivated it?

A: MBCT was developed for acute depression and showed large effects compared to antidepressants

B: MBCT was developed for people with recurrent depression (three or more previous episodes) to prevent relapse; the finding was that mindfulness disrupts depressive relapse by changing the person's relationship with depressive thoughts and moods rather than their content

C: MBCT was developed for generalised anxiety disorder to reduce chronic worry

D: MBCT was developed for chronic pain to increase pain tolerance through mindfulness of bodily sensations

Correct: MBCT was developed for people with recurrent depression (three or more previous episodes) to prevent relapse; the finding was that mindfulness disrupts depressive relapse by changing the person's relationship with depressive thoughts and moods rather than their content

MBCT was developed by Segal, Williams, and Teasdale (2002) specifically to prevent depressive relapse in people who had recovered from three or more episodes of major depression. The key theoretical insight was "differential activation": in recovered depressed patients, low-level sad mood reactivates the same negative thought patterns associated with depression — an association that does not occur in never-depressed people. MBCT trains participants to notice when this reactivation begins and respond with mindful, decentred awareness ("I am having the thought that I am worthless") rather than getting pulled into ruminative processing. Multiple RCTs show MBCT reduces relapse by approximately 40–50% in high-recurrence patients — now recommended in NICE guidelines as equivalent to maintenance antidepressants.

What is "decentring" (or "metacognitive awareness") in MBCT, and why is it considered the central mechanism of change?

A: Decentring means moving away from one's emotional centre of gravity toward a more rational stance

B: Decentring involves observing thoughts as mental events rather than facts — seeing a negative thought as "a thought arising in the mind" rather than "the truth about how things are" — shifting from being embedded in thought to observing thought

C: Decentring involves moving from a self-centred perspective to a more empathic, other-centred perspective

D: Decentring means physically centring oneself through breathing and posture before engaging with difficult thoughts

Correct: Decentring involves observing thoughts as mental events rather than facts — seeing a negative thought as "a thought arising in the mind" rather than "the truth about how things are" — shifting from being embedded in thought to observing thought

Decentring (Segal et al., 2002; also called "metacognitive awareness" or, in ACT terminology, "defusion") is the capacity to observe thoughts as transient mental events rather than direct readouts of reality. Instead of "I am worthless" (fusion — the thought is an experienced fact), the decentred stance is "I notice I am having the thought 'I am worthless'" — creating a witnessing perspective on mental activity. MBCT aims to cultivate decentring through mindfulness meditation practice: participants learn to observe thoughts arising and passing in awareness without being pulled into their content. Teasdale and colleagues showed that MBCT increased metacognitive awareness and that this increase mediated the reduction in depressive relapse.

Compassion-Focused Therapy (CFT) is based on an evolutionary model of emotional regulation systems. What are the three systems and how does CFT target them?

A: Fight, flight, and freeze — CFT targets the freeze response through graded exposure

B: Threat (protection, anxiety/anger), Drive (seeking, pleasure/motivation), and Soothing/affiliation (contentment, safeness, compassion) — CFT aims to downregulate the overactive threat system and activate the soothing system through compassionate mind training

C: Cortical, limbic, and brainstem systems — CFT uses mindfulness to balance cortical modulation of limbic threat responses

D: Attachment, exploration, and social engagement systems — CFT targets all three through compassionate imagery and relationship work

Correct: Threat (protection, anxiety/anger), Drive (seeking, pleasure/motivation), and Soothing/affiliation (contentment, safeness, compassion) — CFT aims to downregulate the overactive threat system and activate the soothing system through compassionate mind training

Gilbert's evolutionary model proposes three affect-regulation systems: (1) The Threat system — evolved to detect and respond to threat; associated with fear, anger, and disgust; fast-acting; (2) The Drive and resource-seeking system — evolved to motivate approach toward resources; associated with excitement, motivation, pleasure; (3) The Soothing/affiliation system — evolved in mammals to regulate distress through social connection and care; associated with contentment, warmth, safeness. Many clients with high shame and self-criticism have a hyperactive threat system, an unfulfilling drive system, and a poorly developed soothing system. CFT targets the soothing system through compassionate mind training: breathing exercises, compassionate imagery, compassionate letter writing, and developing a compassionate self.

Schema Therapy introduces the concept of "schema modes." What is a schema mode and why is it clinically important?

A: A schema mode is the degree to which a schema is activated — schemas can be fully active, partially active, or dormant

B: A schema mode is a current emotional state and associated coping behaviours — the "parts" of the person that are active at any given moment; mode work directly addresses the immediate emotional experience in session rather than the abstract schema

C: A schema mode is the interpersonal role the client adopts in relationships, determined by their attachment style

D: A schema mode is a structured protocol within Schema Therapy specifying which techniques to use at each phase of treatment

Correct: A schema mode is a current emotional state and associated coping behaviours — the "parts" of the person that are active at any given moment; mode work directly addresses the immediate emotional experience in session rather than the abstract schema

Schema modes were introduced by Young to handle clinical presentations — particularly personality disorders — where multiple schemas operate in rapid succession and where the emotional state shifts dramatically within and between sessions. A schema mode is defined as the current emotional state, associated cognitions, and coping behaviours that are dominant at a given moment. Key modes include: Child modes (Vulnerable Child, Angry Child, Undisciplined Child); Dysfunctional Coping modes (Compliant Surrenderer, Detached Protector, Overcompensator); Dysfunctional Parent modes (Punitive Parent, Demanding Parent); and the Healthy Adult mode (the therapeutic goal). Mode work — including chair work and imagery rescripting — directly engages these activated states rather than working at the level of abstract belief.

True or False: Third-wave CBT therapies (ACT, MBCT, DBT) share the view that attempting to directly challenge or change the content of negative automatic thoughts is the most effective route to psychological wellbeing.

Answer: False

This is the key distinction between second-wave CBT and third-wave approaches. Second-wave CBT (Beck's cognitive therapy, REBT) targets the content of thoughts — identifying distortions and generating rational alternatives. Third-wave therapies share the view that the relationship with thoughts is more important than their content, and that attempting to challenge or suppress unwanted thoughts can be counterproductive. ACT uses defusion and acceptance to change the person's relationship with thoughts without changing their content. MBCT uses mindfulness to observe thoughts as mental events rather than facts. DBT balances acceptance and change with mindfulness as a core skill. None of these therapies have abandoned behavioural techniques, but they have moved away from the direct disputation of thought content.

What evidence base supports the third-wave CBT therapies for clinical effectiveness?

A: Third-wave therapies have RCT support but only for personality disorders — no evidence base for anxiety or depression

B: Multiple RCTs and meta-analyses support ACT (anxiety, depression, chronic pain, psychosis), DBT (BPD, self-harm, suicidality), and MBCT (recurrent depression prevention) across diverse populations; effect sizes are broadly comparable to traditional CBT, and for specific populations (e.g., high-recurrence depression) some advantages have been found

C: Third-wave therapies have theoretical support but clinical trials have consistently failed to show effects larger than waitlist control

D: The evidence base consists primarily of case studies and expert consensus rather than RCTs

Correct: Multiple RCTs and meta-analyses support ACT (anxiety, depression, chronic pain, psychosis), DBT (BPD, self-harm, suicidality), and MBCT (recurrent depression prevention) across diverse populations; effect sizes are broadly comparable to traditional CBT, and for specific populations (e.g., high-recurrence depression) some advantages have been found

The third-wave therapies have substantial empirical support. DBT: Linehan's original RCT (1991) showed significant reductions in parasuicidal behaviour and hospitalisation in BPD; multiple replications and a growing evidence base for adolescents, eating disorders, and substance use. MBCT: Three large RCTs demonstrated roughly 40–50% reduction in depressive relapse for patients with ≥3 prior episodes; now recommended in NICE guidelines as equivalent to maintenance antidepressants. ACT: Meta-analyses show effects on anxiety, depression, chronic pain, OCD, psychosis, and workplace wellbeing; A-Tjak et al. (2015) meta-analysis of 39 RCTs showed significant effects vs control, generally comparable to traditional CBT. CFT and Schema Therapy have smaller but growing evidence bases.
