Introduction

Most experienced clinicians have encountered moments in therapy that feel oddly familiar, repetitive, or emotionally charged in ways that seem to exceed the immediate clinical material. A therapist may notice themselves feeling unusually helpless, pressured, criticised, or over-responsible in a session – only to later recognise similar dynamics in the client’s broader relational world. In supervision, these same patterns may quietly reappear, shaping how the therapist speaks, feels, or seeks reassurance (Bernard & Goodyear, 2019).

These experiences are often described under the umbrella of parallel process: the phenomenon whereby relational dynamics from the client’s internal or external world are unconsciously replicated within the therapeutic relationship, and sometimes again within supervision. While the concept is well established within psychodynamic psychotherapy, it continues to evoke mixed reactions. For some clinicians, parallel process feels like a powerful source of clinical information. For others, it can feel exposing, destabilising, or even professionally threatening.

This article explores parallel process as a relational phenomenon rather than a therapist error. By examining its theoretical origins, clinical manifestations, and ethical implications, we consider how parallel process can function both as a blessing and a limitation in psychotherapy. Finally, we focus on how therapists can work with parallel process in ways that serve the client’s therapeutic aims while also supporting the clinician’s reflective capacity and professional growth.

What Is parallel process?

Parallel process refers to the unconscious replication of relational patterns across different therapeutic contexts. Most commonly, it describes the way dynamics from the client–therapist relationship are mirrored in the therapist–supervisor relationship (Searles, 1955; Bernard & Goodyear, 2019). More broadly, it can be understood as the repetition of similar emotional positions, roles, or tensions across interconnected relational systems.

Within psychotherapy, parallel process is not limited to overt behavioural imitation. It often operates at an affective level, shaping emotional tone, expectations, and unspoken assumptions. A client who experiences others as controlling, for example, may evoke feelings of constraint or compliance in the therapist. These same feelings may then surface in supervision, influencing how the therapist presents the case or responds to guidance.

Importantly, parallel process is not a deliberate enactment. It arises through unconscious communication and relational attunement, reflecting the human tendency to organise experience through familiar emotional patterns. When recognised and reflected upon, it can offer a valuable window into the client’s internal world and relational history.

Historical and theoretical origins

The concept of parallel process emerged within psychoanalytic and psychodynamic traditions, particularly in the context of supervision. Early formulations are often attributed to Harold Searles, who observed that supervisors could become emotionally positioned in ways that mirrored the therapist’s relationship with the patient (Searles, 1955).

Michael Balint and colleagues further contributed to this understanding by emphasising how relational patterns are communicated implicitly and enacted rather than verbally articulated. From this perspective, parallel process reflects attempts to convey aspects of experience that have not yet been symbolised or integrated (Balint, 1968).

Subsequent psychodynamic theorists linked parallel process to broader concepts such as transference, countertransference, and projective identification (Ogden, 1979). Contemporary relational and intersubjective approaches have refined the concept further, emphasising that parallel process does not reside solely within the client or therapist, but emerges within the relational field itself (Mitchell, 2000).

How parallel process manifests in the therapy room

Parallel process often announces itself subtly, through shifts in the therapist’s internal experience rather than through dramatic clinical events. Therapists may notice recurring emotional states – such as boredom, urgency, confusion, or self-doubt – that feel disproportionate to the session’s content.

Other signs include feeling pulled into particular roles, such as rescuer, authority figure, or appeaser, or experiencing pressure to act in ways that deviate from one’s usual clinical stance. The therapist may find themselves thinking, I’m doing everything and it’s never enough, or Whatever I say will be wrong, echoing themes present in the client’s life.

These experiences are not inherently problematic. However, when parallel process remains unrecognised, it can narrow therapeutic flexibility. The therapist may begin to respond reactively rather than reflectively, reinforcing the very patterns the therapy aims to transform.

Clinical vignette: The quiet pressure to get it right

Elena, a psychologist with a primarily CBT background, is working with Mark, a 42-year-old client referred for persistent anxiety and work-related stress. Mark presents as conscientious and self-critical, arriving to sessions with detailed notes and a clear expectation that therapy should be efficient and productive. He often asks Elena whether she thinks he is “doing therapy properly.”

Over time, Elena notices a subtle shift in herself. Before sessions, she feels an unexpected sense of pressure to prepare extensively. During sessions, she becomes unusually careful with her wording and finds herself offering reassurance more quickly than she normally would. When Mark appears dissatisfied, she leaves sessions feeling vaguely inadequate, despite objectively following evidence-based protocols.

In supervision, Elena realises that she has begun to mirror Mark’s internal stance: the belief that mistakes are costly and that approval must be earned through performance. This recognition reframes her discomfort. Rather than indicating clinical failure, her experience provides a felt sense of how Mark relates to himself and others. With this awareness, Elena slows the pace of sessions and begins gently naming the anxiety that arises around “getting it right,” allowing Mark to explore this pattern in real time rather than solely through cognitive restructuring.

Parallel process as clinical information

When approached with curiosity, parallel process can serve as a rich source of clinical data. It offers experiential insight into how the client relates to others and how others may experience the client in close relationships (Gelso & Hayes, 2007).

Rather than relying solely on narrative accounts, the therapist gains access to felt knowledge: what it is like to occupy a particular emotional position in relation to the client. This information can deepen formulation, guide timing and pacing, and inform interventions that address relational patterns as they are lived rather than merely described.

From this perspective, parallel process is not an obstacle to therapy but a communicative channel. It reveals aspects of the client’s relational world that may not yet be available to conscious reflection, making it particularly relevant in work with complex trauma, attachment disturbances, and entrenched interpersonal difficulties (Schore, 2012).

When parallel process becomes limiting or risky

Despite its potential value, parallel process also carries risks. Unexamined enactments can compromise therapeutic boundaries, blur roles, or place undue emotional burden on the therapist. In some cases, therapists may feel trapped in repetitive cycles of over-functioning, self-criticism, or emotional withdrawal.

Parallel process can also complicate supervision if it leads to defensiveness, compliance, or avoidance. When supervisors and supervisees are both caught in mirrored dynamics, opportunities for reflection may be reduced rather than enhanced.

Ethically, the key concern is not the presence of parallel process but the absence of reflective awareness. Without sufficient support, therapists may struggle to disentangle their own vulnerabilities from those evoked by the client, increasing the risk of burnout or therapeutic impasse. When such processes remain unexamined, they may constrain therapeutic flexibility and contribute to therapist strain (Gelso & Hayes, 2007; Bernard & Goodyear, 2019).

Clinical vignette: When mirroring narrows the work

James, an early-career therapist, is seeing a client who frequently expresses dissatisfaction with previous professionals. In sessions, the client oscillates between idealising James and subtly questioning his competence. James responds by working harder – lengthening sessions, offering additional resources, and second-guessing his clinical decisions.

Over several weeks, James begins to feel resentful and depleted. In supervision, he presents the case defensively, emphasising how much he is doing for the client while minimising his own frustration. The supervisory conversation becomes strained, with James seeking reassurance rather than reflection.

Only when the supervisor names the pressure in the room – “It feels as though we’re both being asked to prove something here”– does the parallel process become visible. This moment allows James to recognise how the client’s relational pattern has been replicated across both therapy and supervision. With this insight, he is able to re-establish clearer boundaries and approach the client’s dissatisfaction as meaningful clinical material rather than a personal indictment.

Working with parallel process for client and therapist growth

The clinical task is not to eliminate parallel process, but to work with it thoughtfully and ethically. This begins with cultivating awareness of one’s own emotional responses and treating them as signals rather than verdicts.

Supervision plays a central role in this process. By exploring emotional reactions, relational pulls, and moments of discomfort, therapists can transform parallel process from an unconscious enactment into a source of shared understanding. This reflective stance allows therapists to respond more flexibly in the therapy room, modelling curiosity and emotional regulation.

When handled well, parallel process supports not only client change but therapist development. It sharpens relational sensitivity, deepens tolerance for complexity, and reinforces the importance of ongoing reflective practice. In this sense, parallel process becomes less a curse and more a demanding but valuable companion in psychotherapeutic work, deepening both relational awareness and emotional tolerance (Gelso & Hayes, 2007; Mitchell, 2000).

Supervision vignette: Parallel process as a shared discovery

Sofia, an experienced psychotherapist, brings a long-term client to supervision, describing a persistent sense of stagnation. She reports feeling unusually passive in sessions, often waiting for the client to lead, while simultaneously feeling frustrated by the lack of progress.

As Sofia speaks, the supervisor notices a similar atmosphere emerging in the supervisory space: long pauses, careful language, and a mutual hesitation to take initiative. Rather than focusing immediately on technique, the supervisor draws attention to the process itself. “I’m noticing we’re both waiting,” he says. “I wonder if that’s familiar from the work with your client.”

This observation opens a new line of inquiry. Sofia realises that the client’s history of emotionally unavailable caregiving has shaped a relational style in which initiative feels dangerous. The parallel process has quietly reproduced this dynamic across therapy and supervision. Recognising it allows Sofia to experiment with gently naming moments of waiting and uncertainty in the therapy room, creating opportunities for new relational experience rather than continuing the unspoken stalemate.

Conclusion

Parallel process is an inevitable feature of relational work rather than a clinical failure. Its presence reflects the depth of emotional engagement inherent in psychotherapy and the ways human beings communicate relational experience beyond words.

By approaching parallel process with curiosity, humility, and adequate support, therapists can transform mirrored dynamics into meaningful clinical information. In doing so, they not only serve their clients more effectively but also engage in the ongoing relational learning that lies at the heart of psychotherapeutic practice.

Questions therapists often ask

Q: How do I know when I’m experiencing parallel process rather than just having a normal emotional reaction to a session?

A: The difference is usually in the pattern and intensity. You might notice recurring feelings – pressure, inadequacy, boredom, urgency – that seem disproportionate to the session content. Or you may find yourself pulled into a familiar role, like rescuer or appeaser, in a way that subtly shifts your usual stance. When your internal experience starts to echo themes central to the client’s relational world, that’s often a signal that something relational is being enacted rather than simply felt.

Q: What should I do in the moment if I realise I’m being pulled into a particular role?

A: First, slow down. Treat the feeling as data, not as a problem to fix. You don’t need to interpret it immediately. Regain your reflective stance – notice the urge to over-function, reassure, withdraw, or defend. Then consider whether gently naming the dynamic in real time might open space for exploration. The goal isn’t to correct yourself perfectly, but to shift from reacting automatically to responding with awareness.

Q: How can I use parallel process as clinical information without over-interpreting it?

A: Stay grounded in observable patterns. Ask yourself: does what I’m feeling mirror how the client describes relating to others – or to themselves? If your experience aligns with recurring themes in their life, it may offer a felt understanding of their relational style. Keep it tentative. Parallel process is a hypothesis generator, not a verdict. Supervision is where you test whether what you’re noticing deepens formulation or simply reflects your own material.

Q: When does parallel process become ethically concerning?

A: It becomes risky when it goes unexamined and starts shaping your behaviour in ways that narrow flexibility or blur boundaries. Over-extending sessions, working harder to earn approval, withdrawing emotionally, or seeking reassurance in supervision instead of reflection – these are signs the dynamic may be driving you. The ethical issue isn’t that mirroring occurs; it’s that without awareness, it can reinforce the client’s pattern and increase therapist strain or burnout.

Q: How can supervision be used more effectively to work with parallel process?

A: Bring your emotional experience into the room, not just your interventions. Describe moments of pressure, hesitation, defensiveness, or passivity. Pay attention to what’s happening between you and your supervisor – tone, pacing, atmosphere. When supervision shifts from problem-solving to noticing the relational field, parallel process often becomes visible. That shared noticing can loosen stuck dynamics and restore flexibility in the therapy room.
