REBT and Mindfulness: A Brief History
Rational Emotive Behaviour Therapy (REBT) is a cognitive behavioural approach to psychotherapy developed by the American psychologist Albert Ellis (Ellis,
1957,
1962). Ellis created Rational Therapy (RT)—later renamed Rational Emotive Therapy (RET), then, from 1995, REBT—having become disillusioned with psychoanalytic methods in the Freudian tradition which he considered inefficient and untargeted (Ellis,
1995; Still & Dryden,
1998). Using the acronym REBT for all iterations of Ellis’ therapeutic approach, REBT was the first model of psychotherapy to describe how emotional disturbances result from dysfunctional thinking in response to adversity, and to specifically target the disputation and replacement of irrational beliefs with rational beliefs as a primary mechanism for positive emotional change (David et al.,
2005). REBT is considered by many to be the original form of Cognitive Behavioural Therapy (CBT), having been introduced chronologically prior to the preeminent Aaron T. Beck’s early work on cognitive factors in depression which was the precursor to his Cognitive Therapy (CT; Beck,
1963,
1964). Together, REBT and CT were the two pillars underpinning the ‘second wave’ of CBT whereby cognitive and behavioural approaches to psychological treatment became integrated (Thoma et al.,
2015).
REBT and CT share several fundamental similarities and, Ellis suggested, have become more similar over time (Ellis,
2003b). Crucially, both REBT and CT consider thinking, feeling, and behaving as “integrally and interactionally related” (Ellis,
2003b, p. 227). For the purposes of our commentary, particularly when discussions turn to the ‘third wave’ of CBT, it is important to note that REBT and CT are also distinctive approaches with key differences. A detailed assessment of these differences is beyond the scope of this commentary. However, in general terms, REBT is philosophical, humanistic, and largely transdiagnostic whereas CT is rooted in empiricism, scientific reality testing and is more closely tied to psychiatric diagnoses (Ellis,
2003b). REBT focuses on disputing deeply held irrational beliefs which include primary ‘must’ demands, and secondary beliefs relating to awfulizing, low frustration tolerance and self, other and world damning (Ellis & Dryden,
2007). REBT eschews disputing or reality testing higher order thinking processes, such as inferences and negative automatic thoughts, because Ellis considered replacing irrational beliefs with rational beliefs to be most crucial for lasting emotional, behavioural, and psychological change (Ellis & Dryden,
2007). In contrast, CT is primarily concerned with correcting faulty higher order thinking and the functionality of a client’s beliefs within their own value systems and life experiences rather than directly assessing their rationality against pre-ordained ideas (Padesky & Beck,
2003).
Although CT incorporates core belief, or schema, work within its framework, it typically addresses higher order thinking over or before such work. Crucially, CT does not actively incorporate philosophy into its therapeutic process in the way that REBT does (Ellis,
2005). What has become widely known as ‘traditional CBT’ arguably reflects Beck’s CT with integrated behavioural treatment aspects more so than it does Ellis’ REBT, for several reasons not least that it excludes REBT’s philosophic emphasis. As Ellis (
2005) put it, “traditional CBT is far from being the same as REBT” (p. 161). The third wave of CBT, which has risen to prominence in the past two decades, has seen the integration of mindfulness meditation and related practices with aspects of CT (as opposed to REBT) for the treatment of an array of psychological disorders including depression and anxiety (e.g., Segal et al.,
2002).
Western interest in mindfulness philosophy, and mindfulness-based meditation specifically, has grown rapidly in recent decades (Baminiwatta & Solangaarachchi,
2021). Secular mindfulness practice—distinct from mindfulness in the Buddhist tradition but retaining many of its components—has become incorporated into numerous Western psychological therapies (Öst,
2008), and popular apps offering guided mindfulness meditation continue to attract millions of subscribers (Perez,
2020). Mindfulness features prominently in many ancient Buddhist traditions including Theravada, Mahayana, and Vajrayana, but the roots of meditative mindfulness practice found in contemporary Western settings can largely be traced back to Tibetan Buddhism (Dredze,
2020). In Buddhist teachings, mindfulness is seen as one of the ways in which to cultivate self-knowledge and wisdom required to reach the goal of enlightenment, whereupon freedom from suffering is the ‘reward’ for letting go of unhealthy desires and attachments (Keng et al.,
2011).
Mindfulness is a multifaceted concept, and some have observed that this can give rise to confusion regarding what it encompasses (Baer,
2003; Roemer et al.,
2003). The word ‘mindfulness’, for example, is said to simultaneously represent a specific psychological trait, a mode or state of awareness and the practice of cultivating mindfulness itself through meditation (Siegel et al.,
2009). While the umbrella definitions of mindfulness cover a range of related sub-concepts, present moment awareness and non-judgemental acceptance are recognised universally as being central features of mindfulness, and meditation is the most common but not the only method of contemporary mindfulness practice (Baer,
2003; Kabat-Zinn,
1990).
Some scholars, including Albert Ellis, have noted similarities between the teachings of mindfulness and REBT, going so far as to suggest that they may have integrative potential (e.g., Ellis,
2005,
2006; Whitfield,
2006). This is perhaps not surprising, given the integrative potential of mindfulness and CT, which is arguably less philosophic than REBT, has already been indicated within third wave CBT approaches (e.g., Segal et al.,
2002). However, some authors have cautioned against the integration of mindfulness and CBT, of which REBT is one modality, on the grounds that mindfulness and the core principles of CBT are incompatible because the former takes a non-judgemental approach to thoughts while the latter includes cognitive restructuring, and that the concept of mindfulness outside of its Buddhist religious tradition lacks meaning (e.g., Harrington & Pickles,
2009). It is an interesting debate which acts as a backdrop to our critical commentary.
REBT and contemporary applications of mindfulness have followed broadly similar trajectories since their introduction to Western psychotherapy in the mid and late twentieth century respectively having both initially been conceived as clinically oriented psychotherapeutic interventions (Ellis,
1957,
1962; Kabat-Zinn,
1982) before extending into non-clinical and performance-related areas. The development of REBT, and to a large degree its success, has been driven by its founder Albert Ellis, for whom delivering, writing about, and teaching REBT was a life’s work. But if there is perhaps one area of weakness for REBT, as Ellis himself acknowledged, it is an evidence base that although not unconvincing, is not as deep as it might be given its longevity, and is certainly thinner than that of Beck’s CT (Neenan,
2001). Nevertheless, a recent meta-analysis of 84 REBT research studies in clinical, sub-clinical and non-clinical settings, conducted over the last 50 years, concluded that that REBT was “a sound psychological intervention” based on a medium overall effect size (
d = 0.58) for REBT compared to other interventions across outcomes at post-test (David et al.,
2018, p. 304).
The adoption of mindfulness-based interventions within secular Western clinical settings began with the work of Jon Kabat-Zinn who initially developed a Mindfulness-Based Stress Reduction (MBSR) programme for patients living with chronic pain (Kabat-Zinn,
1982). Kabat-Zinn’s work was the catalyst for the integration of mindfulness with elements of CT for the subsequent treatment of depression, anxiety, and borderline personality disorder, among other disorders, often referred to collectively as the third wave of CBT. Notable third wave CBT approaches include Mindfulness Based Cognitive Therapy (MBCT; Segal et al.,
2002), Acceptance and Commitment Therapy (ACT; Hayes et al.,
1999) and Dialectical Behaviour Therapy (DBT; Linehan,
1993). Since their introduction in the 1990’s, third wave approaches have become influential within the CBT movement and have been adopted alongside traditional CBT approaches within health systems such as the UK’s National Health Service (NHS; Tickell et al.,
2020). Findings from meta-analyses of randomised controlled trials (RCTs) generally support the efficacy of third wave CBT approaches across a range of clinical settings and disorder types (e.g., Kuyken et al.,
2016), although the methodological robustness of some RCTs have been questioned (see Öst,
2014).
In recent decades, researchers have come to consider that both REBT and mindfulness may have potential to enhance psychological performance within high performance settings. From the perspective of REBT, this potential is seen to reside in the benefit to high performing individuals of holding rational beliefs over irrational beliefs. From the perspective of mindfulness, cultivating a mindset of non-judgemental awareness of the present moment is hypothesised as being beneficial. Most REBT research within high performance settings has been undertaken within the context of sport, although even here the literature is in its infancy (see Turner,
2019). Encouraging outcomes from REBT have been observed across a range of sporting contexts including soccer (Turner et al.,
2014), Paralympic soccer (Wood et al.,
2018), archery (Wood et al.,
2017), cricket (Turner & Barker,
2013) and squash (Deen et al.,
2017). Beyond sport, there is a smaller but growing literature on REBT’s application in other high performance settings including business (e.g., Turner & Barker,
2015), emergency services personnel (Jones et al.,
2021; Wood et al.,
2021) and the military (Jarrett,
2013), but it is too early for firm conclusions regarding its efficacy in these areas.
The notion that mindfulness practice may enhance mental performance and improve goal-directed outcomes has been investigated in many of the same high-performance settings as REBT, namely sport (e.g., Bühlmayer et al.,
2017), business (e.g., Bostock et al.,
2019) and the military (e.g., Brewer,
2014). The early signs have been encouraging, particularly in sport and business where most of the research has been conducted (Bühlmayer et al.,
2017; Vonderlin et al.,
2020) but, as with REBT and performance, the literature remains in its formative years. A meta-analytic review of nine trials noted that mindfulness practice was linked with decreased psychological stress within sporting settings which the authors noted could lead athletes to more goal-oriented performance (Bühlmayer et al.,
2017). Similarly, a larger meta-analysis of 56 studies conducted by Vonderlin and colleagues (2020) identified that mindfulness-based programmes were effective in promoting the health and wellbeing of employees in various occupational settings including, but not limited to, business. Interest in mindfulness applied to high performance settings is growing rapidly, but there is a widely accepted need for more methodologically robust work—such as randomised controlled studies with active control groups—before firmer conclusions on efficacy can be drawn (Bühlmayer et al.,
2017).
In sum, REBT and mindfulness-based approaches have evolved similarly in that both are now being applied within high performance settings having been originally developed for the clinical treatment of psychological disorders. To date however, despite rare exceptions (e.g., Chenneville & St John Walsh,
2016; Chenneville et al.,
2017), there is a paucity of literature on ‘pure’ REBT (to distinguish between Ellis’ REBT and Beck’s CT) and mindfulness having been actively integrated within clinical or indeed high-performance settings.
