Acceptance and commitment therapy (ACT) focuses on helping patients to behave more consistently with their own values and apply mindfulness and acceptance skills to their responses to uncontrollable experiences.
This article presents an overview of ACT, its evidence base and how general practitioners can apply ACT consistent practice in the primary care setting. It describes pathways for general practitioners to develop further expertise in the approach.
Acceptance and commitment therapy has been associated with improved outcomes in patients with chronic pain (comparable to cognitive behaviour therapy) and several studies suggest that it may be useful in patients with mild to moderate depression. Preliminary evidence of benefit has also been shown in the setting of obsessive-compulsive disorder, psychosis, smoking, tinnitus, epilepsy and emotionally disordered eating after gastric band surgery. Acceptance and commitment therapy starts with a discussion about what the patient wants and how they have tried to achieve these aims. Strategies previously used to avoid discomfort are discussed. Psychoeducation in ACT involves metaphors, stories and experiential exercises to demonstrate the uncontrollability and acceptability of much psychological experience. In its final phase, ACT resembles traditional behaviour therapy consisting of goal setting and graduated activity scheduling toward goals directed by values.
The therapy is less concerned with eliminating unwanted thoughts, emotions and sensations (often seen as the symptoms of psychiatric disorder) and more concerned with cultivating psychological flexibility: the ability to change behaviour depending on how useful to the patient’s life this behaviour is understood to be in the long term. The ACT model predicts people will be most effective when able to:2
Therapy is aimed at strengthening skills in these six overlapping and synergistic processes, collectively referred to as the ‘hexaflex’.2
Evidence for efficacy
Acceptance and commitment therapy was designed to be broadly applicable to a range of life difficulties, including those that do not fit into neat diagnostic categories. Over 50 randomised controlled trials have evaluated the benefits of ACT in the setting of various disorders. In patients with chronic pain it has been shown to be more effective than placebo or ‘treatment as usual’ and comparable to cognitive behaviour therapy.3 Several studies suggest that it may be useful in patients with mild to moderate depression.4 Improvements compared to placebo or treatment as usual has been shown in the setting of obsessive-compulsive disorder (OCD),5 psychosis,6 smoking,7 tinnitus,8 epilepsy9 and emotionally disordered eating after gastric band surgery.10 Preliminary evidence of benefit has been seen in nonclinical settings (eg. worksite stress,11 mental health stigma12 and weight loss13). However, there is room for methodological improvement in the studies undertaken, in particular by employing follow up periods of longer than 12 months and controlling for concomitant treatments. Importantly, meta-analyses of its application to a specific disorder, which are required for the National Health and Medical Research Council Level I evidence of efficacy, have yet to be conducted. However, in the opinion of the author, there is sufficient evidence to warrant the use of ACT as a psychological therapy, particularly if the patient has not responded satisfactorily to a first line cognitive behaviour therapy protocol and/or the treating therapist has greater expertise and experience in ACT than other protocols.
Acceptance and commitment therapy
Acceptance and commitment therapy typically starts with an assessment of what the patient wants. Emotional control goals (eg. ‘I just want to be happy’) are reframed as a means to a more valued life (eg. through asking, ‘And if you felt happier and more confident what would you be doing more of?’). Assessment includes identifying all the things the patient has done to try to achieve their aims and how well these have worked in the short and long term. Acceptance and commitment therapy therapists particularly seek to identify patterns of trying to control or avoid uncontrollable internal experiences, particularly those that disrupt valued living. These can range from obvious (eg. overt avoidance of difficult situations, substance use and oversleeping) to subtle (eg. ‘putting on a front’, ‘holding back’ or ‘not really listening’ during conversations). Motivation to change is ideally born from an appreciation that strategies used until now to reduce discomfort have come at the cost of the life one truly wants.
Psychoeducation in ACT consists of metaphors, stories and experiential exercises to illustrate the uncontrollability and acceptability of much psychological experience and reveal thoughts to be less powerful and limiting than usually regarded. For example, a patient might be taught to interact with a painful self belief (eg. ‘I’m a loser’) by saying the words out aloud, varying the speed, pitch or tone: treating the stimulus as a sound rather than responding to it literally. To illustrate the difference between struggling to suppress such a thought and accepting it, the thought might be written on a card that the therapist first pushes toward the patient while the patient pushes it back, then second, places on the patient’s lap, where the patient practises allowing contact with the thought. Self awareness can be developed by having the patient watch their thoughts and move their finger to indicate when thinking drifts into the past or present, instead of the ‘here and now’. Reasons a patient gives for being unable to change (eg. ‘I was abused’) might be framed as chapters in a book of which there are many, none more important than any other. As reasons for not changing come to mind throughout the day, the patient can label each as another chapter (eg. the ‘I never finished school’ story). Acceptance and commitment therapy encourages patients and therapists to continually develop new and varied strategies to treat thoughts as harmless and unimportant.
In its final phase, ACT resembles traditional behavioural therapy consisting of goal setting and graduated activity scheduling toward goals directed by values. Values are made clear and vivid, often assisted with imagery exercises (eg. ‘Imagine witnessing your 80th birthday party and hearing the tributes of those who knew you. What would you like them to say?’). As individuals pursue goals, further unwanted emotions and thoughts emerge as apparent barriers, to which the acceptance and defusion skills previously introduced are then applied.
While mindfulness meditation (repetitive practice of prolonged attention to present moment sensation) is not incompatible with ACT, neither is it seen as essential. Instead, ACT coaches patients to adopt mindfulness as a quality or attitude with which any planned action is taken.
Applications and contraindications
Acceptance and commitment therapy may be practised either in a step-by-step, formalised way, or, more typically, in a flexible, principle driven way. Acceptance and commitment therapy may be offered as self help, individually or in group, as a brief intervention for high functioning patients or intensively over months for patients with chronic, highly comorbid presentations. Like any psychotherapy, ACT is not suitable for people whose cognitive functioning is impaired such that they have difficulty comprehending and generating answers to routine assessment questions or virtually no substantive memory of previous conversations. It is not appropriate for individuals who are floridly psychotic, intoxicated, require emergency medical treatment or have organic brain injury.
In many trials ACT has been used in conjunction with pharmacotherapy to good effect.5–7 Individuals should have stable type and dose of any antidepressant, mood stabiliser or antipsychotic medication before commencing ACT. The use of quick-acting benzodiazepines (eg. alprazolam or oxazepam) is incompatible with the ACT aim to reduce experiential avoidance. If individuals are using the equivalent of more than 15 mg diazepam, a controlled benzodiazepine reduction regimen is recommended and progress is unlikely to be satisfactory unless individuals are willing to work toward this. Acceptance and commitment therapy may assist with individuals coping with the discomfort of this reduction, although this has not been empirically evaluated.
ACT resources for the primary care clinician
See Resources for useful books, websites and a DVD. Simple strategies the clinician can employ include:
Take care not to reinforce societal messages that particular emotions or thoughts need to be eliminated before life enhancing actions can be taken.
Model acceptance of uncomfortable life experiences, including appropriate self disclosure.
Model defusing from ‘bossy’/’nagging’/’persuasive’ rules (directions from the mind): again, including appropriate self disclosure (eg. ‘My mind is always telling me to fit more patients in a day; if I let that thought dictate my behaviour I would work myself to death, because there are always more patients to see. Instead, I might thank my mind for the suggestion and proceed to work with my planned schedule’).
Use defused language when reflecting the patient’s psychological experience (eg. if the patient says, ‘I’m weak’, reflect, ‘You’re having the thought ‘I’m weak”).
Ask patients, ‘What’s the next step you could take to live more like the way you want to in the area of (relationships, work, recreation, health)’ and check their progress in that area the next time you see them.

Acceptance and commitment therapy was designed as a simple, yet powerful, set of transdiagnostic processes that have broad applicability to a range of life difficulties including those that do not fit into neat diagnostic categories. Its emphasis on the normality of human suffering, highlighting to clinicians the commonality of experience shared with patients, has created a training and research community characterised by compassion, supportiveness and creativity that rarely fails to touch and inspire those who become connected with the work.
Interested practitioners can attend introductory workshops, now regularly available in Australia. Acceptance and commitment therapy workshops emphasise experiential learning through practising mindfulness and acceptance of personally uncomfortable thoughts and emotions. Being trained in ACT has been shown to enhance psychotherapeutic outcomes even when the practitioner employs other therapeutic approaches,14 so experiencing the principles in action may help to facilitate ACT consistent interactions with patients, even without additional technique training. The Australian New Zealand chapter of the Association for Contextual Behavioural Science (see below) provides opportunities to further develop skills
