This is a crucial shift: it repositions therapy as a site where the client’s suffering can be understood not only through the lens of pathology but also through the lens of social injury and relational deprivation. 1.3 AIM OF THE ARTICLE: DEFINITION, DIFFERENTIATION, PRINCIPLES, AND CLINICAL STRATEGIES This article proceeds from a central thesis: radical psychotherapy has re-emerged as a response to the widening gap between intrapsychic explanations of distress and the socio-structural realities that generate and sustain that distress. The aim is therefore fourfold. First, we clarify what radical psychotherapy is : not a unified school, but a family of approaches linked by a commitment to contextualized suffering, power-awareness, and ethically oriented healing. This includes traditions that have explicitly used “radical” to describe behavioral approaches, such as radical behavioral psychotherapy and its contemporary examples [6], along with functional analytic psychotherapy, which frames change through the analysis of behavior-in-relationship and integration across therapeutic models [7]. Radical behaviorism has also been explored as a conceptual lens that can widen psychotherapy’s explanatory power beyond mentalistic reductionism, emphasizing observable functions of behavior without erasing meaning [8]. These traditions matter here because they demonstrate that “radical” is not synonymous with “political”: it can also mean methodologically foundational, returning to first principles about how change occurs. Second, we differentiate radical psychotherapy from strictly individualistic clinical models. The differentiation is not an attack on established therapies, but a reframing: many standard techniques (e.g., exposure, cognitive restructuring, mindfulness, relational repair) can be deployed either in a decontextualized manner or within a radical frame that explicitly acknowledges power, oppression, and the moral ecology of suffering. The difference often lies less in the technique than in the interpretive and ethical container. Third, we articulate core principles: depathologizing language; reflexivity about power in the consulting room; the integration of social determinants into case formulation; and the repair of agency and dignity as therapeutic outcomes. Experiential and person- centered traditions contribute an important dimension here. The “radical impact of experiencing” on psychotherapy theory underscores that transformative change often occurs through crossings, moments where experience disrupts rigid theoretical boundaries and reorganizes what is possible for the self [9]. This resonates with radical therapy’s historical emphasis on affect, embodiment, and liberation from internalized oppression [10]. Fourth, we propose a set of clinical strategies consistent with a psychotherapist- scientist stance: strategies that are conceptually coherent, ethically defendable, and practically implementable. This includes power mapping, contextual case formulation, shame and internalized oppression work, and relational interventions that strengthen agency without collapsing therapy into activism. We also address typical objections, especially the worry that “radical” becomes ideological, by emphasizing that radical psychotherapy is, at its best, client-centered in an expanded sense: it centers not only the client’s inner world but also the reality of the client’s world.
