Carl Rogers's Congruence and Incongruence: Authenticity and Psychological Change

Research figure: Carl Rogers · Written by Artificial Sapiens

Carl Rogers used congruence to describe the integration of experience, awareness, and self-understanding. Incongruence arises when significant lived experience is excluded from, distorted within, or inconsistently represented by a person's conscious self-concept. In psychotherapy, Rogers also used congruence for a related but distinguishable quality of the therapist: genuineness or internal integration in the therapeutic relationship. These two applications belong to a coherent theory of psychological change, yet they occupy different positions in its explanation. Client incongruence is a proposed condition associated with vulnerability and distress; therapist congruence is a proposed relationship condition facilitating clients' increasing openness to experience. The concepts emerged in a historical theory and have subsequently been investigated with instruments and research designs of varying strength. Rogers, 1957; Rogers, 1959; Kolden et al., 2018.

What Congruence Means in Rogers's Psychology

Congruence is a relationship among different aspects of psychological functioning. Rogers's most influential definition concerns whether experiences available to the person are accurately symbolized in awareness and incorporated into the self-concept. An individual who acknowledges anger, fear, attachment, uncertainty, affection, and conflicting wishes as part of what they are experiencing can understand and respond to those experiences with greater integration. Congruence does not demand emotional serenity or an idealized personality. A person may be congruent while anxious, ambivalent, grieving, or uncertain, because the issue is the accurate recognition and accommodation of experience rather than the pleasantness of its content. Rogers, 1959.

The word also has an interpersonal application. When Rogers described a therapist as congruent, he meant that the therapist was personally present and aware of the feelings and attitudes occurring within the relationship. This capacity gives integrity to the interaction. A therapist who experiences concern, confusion, tenderness, or frustration must first register the feeling accurately and then exercise judgment about whether, when, and how it should affect communication. Genuineness therefore includes a disciplined relationship between awareness and expression. It is compatible with restraint and professional boundaries. Rogers, 1957; Kolden et al., 2011.

The two senses converge on a broader proposition: psychological functioning becomes more flexible when experience can be acknowledged and represented with less distortion. Nevertheless, evidence for one form of congruence does not automatically establish every claim about the other. A measure of a therapist's genuineness cannot, by itself, determine whether a client's self-structure has become more integrated.

Incongruence: The Discrepancy Between Self and Experience

In Rogers's personality theory, the self is an organized configuration of perceptions and values that a person recognizes as related to “me.” Experiences arrive continuously through bodily states, emotions, sensations, relationships, and action. Some readily fit the established self-concept; others challenge it. Incongruence refers to a discrepancy between the experienced life of the individual and the self-picture used to interpret that life. Rogers's mature 1959 statement explicitly distinguished these constructs and their functional relationships. Rogers, 1959.

Consider someone whose self-description is “I never feel angry toward people I love.” Irritation toward a close friend threatens this description. The person may reinterpret anger as fatigue, dismiss it as irrelevant, blame another circumstance, or experience discomfort without recognizing its source. Such examples are illustrations of Rogers's theoretical process, not diagnoses or empirical demonstrations of unconscious mental mechanisms in any particular individual. Incongruence can also arise where a person admires a socially rewarded identity but experiences contrary needs or values that feel difficult to acknowledge.

Rogers associated substantial incongruence with vulnerability to threat and anxiety. A new experience may call an established self-definition into question. The individual can then defend the existing self-organization by denying or distorting aspects of the experience. Anxiety is understandable in this model because accurate awareness might require a revision of identity, attachment expectations, or the conditions on which self-regard has depended. The formulation is a proposed process linking identity organization to emotion, not a general diagnostic account of anxiety disorders. Rogers, 1951; Rogers, 1959.

Awareness, Symbolization, and Defense

In Rogers's terminology, symbolization is the process by which experience is represented in awareness. Accurate symbolization allows a person to recognize a felt response as belonging to their own experience. Distorted symbolization assigns it a meaning that makes it fit a prior self-concept; denial keeps it outside conscious recognition as a self-experience. The theory concerns the organization of experience and meanings, and its vocabulary reflects the phenomenological and clinical intellectual setting in which Rogers worked. Rogers, 1959.

A defensive interpretation may provide immediate continuity to identity while limiting the person's ability to learn from present circumstances. Rogers envisaged constructive change as increased capacity to symbolize previously threatening material and reorganize the self-concept accordingly. This is a developmental conception of psychological integration rather than a command to disclose every thought or revise every deeply held commitment. Awareness can coexist with deliberation about privacy, safety, cultural obligations, and moral responsibility.

Conditions of Worth and the Development of Incongruence

Rogers proposed that the need for positive regard can become entangled with conditions of worth: learned rules about which feelings, needs, or forms of behavior make a person acceptable. When acceptance appears conditional on being cheerful, compliant, successful, self-sufficient, or otherwise approved, an individual may come to evaluate experience according to those external conditions. This is one pathway through which a self-concept can become increasingly selective. Rogers's 1959 theory connected conditions of worth, self-regard, distorted awareness, and vulnerability. Rogers, 1959.

The theoretical connection deserves careful interpretation. Social expectations can also support cooperation, ethical development, and self-regulation. The central question is how rigidly a person must reject awareness of genuine experience to preserve a valued identity. Later empirical questions include which family, cultural, and interpersonal environments intensify this pattern, how it changes across development, and whether acceptance-oriented therapy modifies it.

Historical Development: From Client-Centered Therapy to the 1959 Theory

Rogers's ideas emerged through clinical work and research rather than a single moment of invention. His early development of nondirective and client-centered counseling shifted emphasis toward clients' subjective frames of reference, their capacity to explore their own experience, and the quality of the therapeutic relationship. His 1942 book, Counseling and Psychotherapy, helped present the nondirective approach; the 1951 Client-Centered Therapy elaborated a more explicit psychology of the self, adjustment, threat, and defensive processes. The later terminology of congruence gained precision as his broader theoretical framework developed. Rogers, 1951; Cain and Murphy, 2026.

At the University of Chicago, Rogers and collaborators combined recorded treatment material with coordinated studies of psychotherapy process and personality change. The 1954 volume edited by Rogers and Rosalind Dymond documented this collective research program. Its historical contribution includes attempts to move claims about the self from clinical interpretation toward observable changes and comparative measurement. The book's research contributions should be credited to the participants and chapter authors, while Dymond's substantive role as coeditor and investigator is retained. Rogers and Dymond, 1954.

Rogers's 1957 paper, “The Necessary and Sufficient Conditions of Therapeutic Personality Change,” organized the psychotherapy proposition into six explicitly formulated conditions. His 1959 chapter, “A Theory of Therapy, Personality, and Interpersonal Relationships, as Developed in the Client-Centered Framework,” provided a much more extensive systematic account of constructs, development, behavior, and therapeutic change. Reading the two texts together clarifies the difference between the practical relationship claim and the theoretical explanation of client incongruence. Rogers, 1957; Rogers, 1959.

The vocabulary continued to circulate across humanistic psychology, counseling, education, and later experiential therapies. Subsequent developments introduced their own techniques and research programs. Congruence in present-day integrative practice may retain Rogerian inspiration while being operationalized differently. The history therefore requires attribution by publication, research group, and theoretical lineage rather than treating every later use of “authenticity” as an unchanged Rogers construct. Cain and Murphy, 2026.

The Two Clinical Positions of Congruence

Client Incongruence as a Condition of Vulnerability

Condition two in Rogers's 1957 formulation places the client in a state of incongruence associated with vulnerability or anxiety. The premise is that significant psychological change concerns someone for whom the existing organization of experience is creating difficulty. The term “client” was deliberately part of his therapeutic language, and the condition is best interpreted within the full theory rather than as an independent psychiatric criterion. A client can experience distress for biological, social, traumatic, economic, and situational reasons that require explanations and treatment approaches beyond the Rogers model. Rogers, 1957.

Therapist Congruence as a Relationship Condition

Condition three concerns the therapist being congruent or integrated within the therapeutic relationship. A therapist needs access to their genuine responses in order to participate without a pervasive professional façade. This requirement is not an invitation to center the encounter on the therapist's personal life. The client remains the primary focus of the work, and communication must serve that client's understanding and safety. Professional congruence involves recognizing feelings, considering their relevance, and deciding whether any disclosure or clarification advances treatment. Rogers, 1957; Kolden et al., 2018.

A practitioner may feel uncertain about an interpretation and express that uncertainty in a measured way. Another may notice a strong urge to reassure and choose to explore the client's experience instead. Both examples illustrate awareness guiding therapeutic judgment. By contrast, bluntly revealing an unprocessed reaction may burden the client. Emotional candor becomes therapeutically meaningful through timing, responsiveness, and boundaries.

A Process Linking the Relationship to Self-Reorganization

Rogers expected an empathic, accepting, and congruent relationship to reduce threat and permit the client to explore experiences previously difficult to integrate. As the person attends more closely to emotional and bodily experience, self-definitions may become more differentiated and flexible. Over time, the individual may respond to current realities with fewer identity-preserving distortions. This is the internal logic of the model. The precise causal sequence remains an empirical hypothesis: it requires measurement of therapist behavior, perceived relationship, client experience, and later outcome over time, rather than evidence of association at a single assessment. Rogers, 1959; Kolden et al., 2018.

Congruence Among the Six Conditions of Therapeutic Change

Rogers's 1957 statement proposed that enduring constructive personality change depends on a conjunction of conditions: psychological contact; a vulnerable or incongruent client; a congruent therapist; unconditional positive regard; empathic understanding; and at least some communication of the therapist's empathy and positive regard to the client. The theory is conjunctive: it is about how several interpersonal and psychological conditions operate together. A single condition removed from that framework cannot substitute for the whole proposition. Rogers, 1957.

The claim of necessity is stronger than a claim that genuineness is commonly helpful. It would imply that therapeutic personality change cannot occur in its absence. The claim of sufficiency is stronger still: it proposes that the stated combination is enough for therapeutic change. Establishing either claim would require carefully defined constructs, reliable measurement, evidence across diverse settings, and designs able to distinguish relationship qualities from expectancy, client resources, concurrent events, and treatment-specific techniques. Modern evidence does not settle these universal causal propositions. Hill, 2007.

Empathic understanding describes a therapist's responsive grasp of a client's internal world. Unconditional positive regard describes a nonpossessive accepting stance toward the person. Congruence describes integration and genuineness in the therapist's participation. All three can be present within the same exchange, and measures may overlap, but they are conceptually distinct. In particular, warmth alone does not demonstrate congruence, and expressing a sincere opinion does not by itself demonstrate empathy. Elliott et al., 2018; Kolden et al., 2018.

Psychological Change and the Question of Authenticity

In Rogers's account, change involves increasing openness to one's experience, revising rigid self-structures, and relying more effectively on experienced evaluation rather than external conditions of approval. “Authenticity” can be useful contemporary shorthand, but it carries additional meanings in moral philosophy, social psychology, and popular culture. The Rogerian construct should remain anchored in experience, awareness, self-concept, and therapeutic relationship rather than reduced to spontaneous self-expression. Rogers, 1959.

A person may genuinely recognize a difficult emotion without acting upon it. Recognition can broaden choice because thought and action become responsive to better information about the person's situation. Conversely, a behavior that feels spontaneous may still reflect habit, learned roles, impulsivity, or social pressure. Authenticity therefore requires an account of self-understanding and agency; momentary intensity of feeling is an unreliable standalone indicator.

Change Without a Perfectly Unified Self

Human experience is variable and context-sensitive. People occupy multiple roles, hold values that sometimes conflict, and revise self-understandings in response to life events. Rogers's “fully functioning” description was explicitly process-oriented: continued openness and movement mattered more than permanent arrival at an ideal endpoint. Congruence can accordingly be treated as a direction of increased integration rather than a binary classification into authentic and inauthentic people. Rogers, 1959; Cain and Murphy, 2026.

Interpersonal Safety and the Limits of Disclosure

Recognition of experience and disclosure of experience are different psychological acts. In some environments, describing every feeling is unsafe or culturally inappropriate. A person can be inwardly congruent while selectively communicating with others. Within psychotherapy, the clinician's responsibility includes managing the therapeutic frame, confidentiality, power differences, and risk. Genuineness is compatible with reflective silence, consultation, boundaries, and repair of relational misunderstandings. Modern discussions of therapeutic congruence emphasize its interpersonal sensitivity as well as self-awareness. Kolden et al., 2018.

From Clinical Constructs to Research Measurement

The scientific appeal of Rogers's program included the insistence that claims about change should be subjected to systematic observation. The Chicago research program used multiple perspectives and measures to study changes in self-perception and adjustment. Self–ideal comparisons and Q-sort procedures attempted to give observable expression to a client's organization of the self. The Q-sort method itself is associated with William Stephenson, and its appearance in Rogers's research does not transfer methodological authorship to Rogers. The 1954 studies belong to a network of researchers, including Rosalind Dymond, rather than to one investigator alone. Rogers and Dymond, 1954.

Self–ideal discrepancy measures a person's reported difference between how they describe themselves and how they would ideally like to be. It captures one operationalization of self-organization, but it is not identical to Rogers's core distinction between organismic experience and self-concept. Someone may show a large self–ideal gap while accurately acknowledging their present characteristics. Another may present a small gap despite defensively excluding important feelings from awareness. A scientifically adequate interpretation must say precisely what was measured and avoid sliding between related but different discrepancies.

The Barrett-Lennard Relationship Inventory brought another research tradition to therapist relationship qualities. G. T. Barrett-Lennard's 1962 investigation examined dimensions of therapist response and client perception, involving 42 clients and 21 therapists in its original sample. Its conceptual dependence on the Rogerian therapeutic-conditions framework does not make Barrett-Lennard's inventory Rogers's own invention. The study also illustrates how client-rated relationship qualities can be collected longitudinally, while limitations of small and nonrandom samples constrain causal inference. Barrett-Lennard, 1962.

Measurement of genuineness has involved client ratings, therapist self-report, observer judgments, and coding of interaction. These perspectives do not necessarily agree. A client may experience a therapist as genuine because the relationship feels understandable, while an observer may focus on verbal immediacy or emotional consistency. Self-ratings can be influenced by professional ideals or self-awareness itself. Reliability, validity, source of ratings, time of assessment, and theoretical orientation all affect interpretation. Kolden et al., 2011; Kolden et al., 2018.

What the Empirical Evidence Shows

Therapist Congruence and Outcome: The 2011 and 2018 Meta-Analyses

Kolden, Klein, Wang, and Austin's 2011 meta-analysis synthesized 16 studies involving 863 clients and reported a weighted association between therapist congruence/genuineness and improvement of r = .24, with a 95% confidence interval from .12 to .36. This was evidence for a positive relationship across the studies reviewed, subject to their designs and measurement limitations. Kolden et al., 2011.

The updated 2018 meta-analysis by Kolden, Wang, Austin, Chang, and Klein included 21 studies and 1,192 clients. Its aggregate correlation was r = .23 (95% CI [.13, .32]), corresponding to an estimated standardized effect d = .46 under the authors' transformation. This result supports a modest-to-moderate positive association between measured therapist congruence and treatment improvement. It does not mean that 23% of outcomes were caused by congruence, nor that authenticity alone produces change. The samples and operational definitions varied, and the researchers discussed patient contributions, diversity, and research limitations. Kolden et al., 2018.

The 2018 review updates the earlier evidence base and should not be counted as an independent replication with entirely separate participants. Meta-analytic sample size increases precision for the assembled observational relationships, but interpretation remains constrained by primary-study quality, possible common-method variance, and the degree to which the studies independently captured congruence rather than general alliance or perceived empathy.

Comparisons With Other Therapeutic Relationship Factors

Elliott, Bohart, Watson, and Murphy's 2018 review of therapist empathy included 82 independent samples and 6,138 clients; its aggregate association with outcome was r = .28, 95% CI [.23, .33]. This is a distinct relationship dimension, assessed in a broader body of studies. Comparing .28 with .23 does not establish the causal importance of empathy relative to congruence because samples, definitions, rater sources, and study designs differ. The meaningful finding is that multiple correlated aspects of therapeutic relationships show links to outcomes across approaches. Elliott et al., 2018; Kolden et al., 2018.

Three recurring questions remain central. First, does observed therapist congruence predict later change after controlling for earlier symptom improvement? Second, do clients who improve become more likely to rate their therapists as genuine? Third, can congruence be experimentally changed without simultaneously changing empathy, alliance, expectations, or therapist responsiveness? Associations cannot answer these questions on their own.

Outcome Studies of Person-Centered Experiential Therapy

The PRaCTICED pragmatic randomized noninferiority trial compared person-centred experiential therapy with cognitive behavioral therapy for moderate or severe depression in English psychological therapy services. It studied a contemporary manualized form of person-centered experiential treatment, not an experimental isolation of Rogers's 1957 congruence condition. Its outcomes therefore inform the evidence base for a later treatment family while leaving the specific causal status of therapist genuineness unresolved. Barkham et al., 2021.

Guideline recommendations are similarly treatment-, problem-, and population-specific. NICE guideline NG222 discusses psychological treatment choices for adult depression, including counseling delivered through empirically validated depression-focused protocols and shared decisions that take patient needs and preferences into account. Such recommendations cannot be converted into a universal prescription for Rogerian therapy or a diagnosis of incongruence. NICE, 2022.

Evidence Status

Established: Rogers's original publications place congruence and incongruence centrally in his account of self and psychotherapy; the published 2011 and 2018 syntheses document positive average associations between rated therapist genuineness and treatment outcomes. Established also is the historical fact of extensive efforts to operationalize relationship conditions and the self in psychotherapy research. Rogers, 1957; Kolden et al., 2018.

Supported with limits: Therapist congruence may contribute to a productive therapeutic relationship, but it is entangled with client characteristics, empathy, alliance, professional skill, and the timing of measurement. Limited: Evidence that a reduction in theoretical self–experience incongruence mediates outcome across populations and treatments remains more difficult to establish than evidence concerning global relationship ratings. Contested: The universal necessity and sufficiency of Rogers's complete six-condition proposition. Hill, 2007; Cain and Murphy, 2026.

Scientific Critiques and Alternative Explanations

Necessary, Sufficient, or Facilitative?

Clara E. Hill's 2007 response to the reprinted 1957 Rogers paper challenged the interpretation that the six conditions are universally necessary or sufficient. Hill considered them potentially facilitative and argued for a broader account of change involving expectations, corrective experiences, interpersonal behavior, and boundaries. Her article is a theoretical and clinical critique, not the final experimental refutation of each condition. It makes the evidential burden explicit: the strength of Rogers's formulation should be evaluated condition by condition and for the conjunction as a whole. Hill, 2007.

How Different Theories Explain the Same Experience

A gap between the person's preferred self-description and felt experience can also be analyzed through cognitive models of beliefs and appraisal, affect regulation, autobiographical memory, attachment, self-discrepancy, social identity, or behavior shaped by reinforcement. These approaches differ in their explanatory targets and experimental methods. Agreement that self-interpretation matters does not establish that the full Rogerian organismic theory is uniquely correct. Rogers's distinctive contribution lies in how he connected experiential awareness and self-organization to a hypothesized interpersonal process of therapeutic change.

The Problem of Circular Explanation

A theory risks circularity if incongruence is inferred whenever a person suffers and congruence is inferred whenever the person improves. Rigorous research requires indicators specified independently of the very outcomes they are intended to explain. For therapist genuineness, ratings made early in treatment and subsequent standardized outcomes offer a stronger sequence than contemporaneous retrospective global impressions. For client incongruence, repeated experience and self-concept assessments may be informative, but the indicators need demonstrated validity, sensitivity to change, and cross-cultural interpretability.

Cultural Variation and Professional Power

Terms such as “genuine,” “open,” and “expressive” may be interpreted differently across cultures and situations. A restrained communication style may express respect and careful listening rather than interpersonal distance; explicit emotional discussion may be helpful in one setting and intrusive in another. Cultural competence requires assessing how particular clients understand authentic engagement, relational safety, family commitments, and personal disclosure. The therapist's power and the client's vulnerability make consent, pacing, confidentiality, and responsiveness part of the ethical setting of congruence. Kolden et al., 2018; Cain and Murphy, 2026.

Gendlin's Reformulation and Research Attribution

Eugene T. Gendlin, collaborating historically within the broader Rogers research environment, independently developed a philosophical and experiential line of inquiry. His 1959 paper “The Concept of Congruence Reformulated in Terms of Experiencing” explicitly proposed a change of emphasis from the contents of awareness to the functioning of experiencing. The document is a primary source for Gendlin's own contribution; it must not be silently presented as an original Rogers formulation. The later Focusing approach also carries Gendlin's authorship. Gendlin, 1959.

Gendlin's intervention illuminates a conceptual tension in Rogers's original definition. If awareness and experience are treated as corresponding contents, researchers need some way to specify experience independently of awareness. If experiencing is an unfolding process, new meanings may emerge during reflection rather than simply being retrieved from a preexisting hidden inventory. This distinction affects the philosophy of emotion and the design of process research. Both lines belong in the historical discussion while preserving their separate intellectual owners.

The Chicago measurement tradition likewise required contributions from Rosalind Dymond and other investigators; Barrett-Lennard developed his own relationship inventory; William Stephenson is associated with the Q-methodological framework. Such distinctions make the history more accurate and help readers evaluate which original publication supports a specific claim. Rogers and Dymond, 1954; Barrett-Lennard, 1962.

Clinical Implications and Responsible Interpretation

For a clinician, congruence offers a useful reflective question: Is my awareness of what is happening within this relationship sufficiently clear to respond responsibly? A therapist can check whether an intervention expresses an accurate and helpful understanding of the client's perspective, whether personal reactions are being processed appropriately, and whether professional habits are distancing the clinician from the encounter. These are possible applications of the theory within professional training and supervision; the right clinical response depends on patient needs, the care setting, and relevant practice standards. Kolden et al., 2018.

For clients, discussion of incongruence may offer a framework for reflecting on tensions among feelings, personal values, relationships, and the roles they feel obliged to maintain. Psychological difficulty can also follow trauma, neurological illness, mood disorders, structural adversity, unsafe relationships, medication effects, or many other pathways. A conceptual description of inner conflict cannot replace comprehensive clinical assessment where symptoms cause significant distress or impairment. Incongruence is a Rogerian theoretical construct, not a DSM or ICD diagnostic category.

Therapeutic disclosure requires especially careful judgment. A practitioner's statement about their immediate experience should be considered in relation to purpose, client preference, impact, risk, and professional boundaries. Therapeutic genuineness does not excuse coercion, hostility, abrupt self-disclosure, or exclusion of evidence-based interventions where these are clinically indicated. People deciding about care should receive information about the actual evidence for treatment options relevant to their condition and preferences. NICE, 2022.

Contemporary Interpretation of Rogers's Legacy

Rogers established congruence and incongruence as linked constructs spanning personality, lived experience, and psychotherapy process. His contribution is historically identifiable in texts from 1951 through 1959 and in the Chicago research program. Subsequent research has provided quantitative evidence that therapist genuineness relates to favorable outcomes. It has also exposed the need for more refined causal studies, careful distinctions among self–ideal discrepancy, self–experience integration, and relationship ratings, and culturally responsive operational definitions. Rogers, 1959; Kolden et al., 2018.

The 2026 second edition of David J. Cain and David Murphy's Person-Centered Psychotherapies places the wider contemporary family of approaches in a framework of theory, research, clinical mechanisms, and criticism. It provides a current synthesis for the field, while Rogers's historical propositions remain identifiable as their own primary-source claims. Studying congruence is scientifically most fruitful when the theoretical concept, the operational measure, the temporal pattern of change, and the relevant evidence strength are each explicitly stated. Cain and Murphy, 2026.

Frequently Asked Questions

What is the simplest definition of congruence in Carl Rogers's theory?

Congruence describes accurate integration of lived experience with awareness and self-understanding. In the therapist, it also names an internally genuine way of participating in the relationship. The two applications are related but have different roles in Rogers's therapy model. Rogers, 1957; Rogers, 1959.

What is an example of incongruence?

A person may consciously believe that they never feel resentment, while repeatedly experiencing resentment that they dismiss, mislabel, or find difficult to acknowledge. This illustrates a possible gap between a self-description and experience; it does not establish a diagnosis or prove that a hidden psychological process has occurred in a given individual.

Is incongruence the same as the difference between the real self and ideal self?

These formulations overlap but are not identical. Self–ideal discrepancy compares current and preferred self-descriptions. Rogers's self–experience incongruence concerns the fit between experience and conscious self-representation, including experiences not accurately symbolized in awareness. Measurement studies must identify which difference they have actually assessed.

Does being authentic mean expressing every emotion?

No. Awareness and communication are separate processes. Congruence in a therapeutic relationship requires thoughtful judgment about relevance, timing, client welfare, and boundaries. Unfiltered disclosure can conflict with professional responsibility. Kolden et al., 2018.

Does research show therapist genuineness improves therapy outcomes?

Meta-analytic research finds a positive association. The 2018 review reported r = .23 across 21 studies and 1,192 clients. That association supports the importance of genuineness while leaving open causal pathways, client contributions, and the universal necessity or sufficiency of the six conditions. Kolden et al., 2018; Hill, 2007.

Is congruence a mental health diagnosis or a therapy method by itself?

Congruence is a theoretical construct and a relationship quality, rather than a diagnosis. Therapist genuineness can occur within different psychotherapy approaches, and clinical treatment must be selected on the basis of the person's presentation, preferences, and evidence for the intervention. NICE, 2022.
