According to the 2024 ICF Coaching Snapshot, an astonishing 85% of coaching professionals report that clients are asking for help with mental wellbeing. This marks a significant shift in the coaching landscape, with business and career issues being the most commonly stated reasons for clients' poor mental wellbeing and subsequent requests for coaching support.

This is not a trend that coaches can afford to ignore. It is not a trend that can be navigated by simply being a good listener. It requires genuine mental health literacy — a structured understanding of what mental health is, how it changes over time, what early warning signs look like, and crucially, where the boundary between coaching and clinical care lies.
This blog draws on current research and evidence to explore the mental health dimension of coaching work, and to offer a practical framework for coaches who want to support their clients well — and responsibly.
Mental Health Is Not a Binary State
One of the most important shifts in contemporary mental health understanding is the recognition that mental health is not simply something you have or do not have. It exists on a continuum, and every person moves along it across their lifetime in response to circumstances, stress, relationships, and environment.
Mental health, like physical health, exists on a continuum. It is a dynamic changing state that can deteriorate or improve given the right set of circumstances. Mental health concerns, if identified and treated early, have the potential to be temporary and reversible. Canada.ca
The two continua model of mental illness and mental health holds that both are related but distinct dimensions. Mental illness and mental health are not simply opposite ends of the same scale — one continuum indicates the presence or absence of mental health, the other the presence or absence of mental illness. The absence of mental illness is a minimal outcome from a psychological perspective. PubMed Central
For coaches, this framing has significant practical implications. A client who appears to be functioning well — meeting goals, performing at work, maintaining relationships — may simultaneously be struggling internally in ways that are not yet visible. The coaching space, when it is psychologically safe and properly structured, is often where those struggles first surface.
The mental health continuum typically moves through stages of thriving, struggling, and overwhelmed — a dynamic range where individuals can move between stages in response to life events, stress levels, and personal circumstances. Onemedicinewellness
Understanding where a client currently sits on that continuum — and being attentive to movement along it — is a foundational skill for any coach working at depth.
The Coach's Role: Clearly Defined, Genuinely Important
There is an important and often misunderstood distinction between what a coach does and what a therapist or clinician does. Getting this distinction right is not a matter of professional gatekeeping — it is a matter of client safety and ethical practice.
A coach facilitates reflection and behaviour change. They provide a safe, non-judgmental space. They support wellbeing and perspective-taking. They work with present and future goals. A therapist diagnoses and treats mental health conditions, explores trauma and past experience, and provides specialised clinical interventions.
Although therapy and coaching are distinct areas of specialism, there is a significant grey area where clients' needs could be addressed by both therapists and coaches. However, for clients presenting specific mental health challenges — including severe anxiety, signs of depression, drug addictions, or personality disorders — the more appropriate route is therapy. British Psychological Society
The distinction matters — but it should not lead coaches to treat mental health as something entirely outside their remit. The idea that coaching functions only with a 'mentally healthy' client does not hold up to scrutiny. Mental health cannot be defined as a simple 'have or have not', and coaching inevitably takes place with people who are somewhere on a continuum of psychological functioning rather than at a fixed point of optimal health. Brookes University
The practical question for any coach encountering emotional or psychological content is not simply "is this person well enough for coaching?" but rather "what does this person need right now, and is coaching the right vehicle for it?"
Why Mental Health Literacy Matters in Coaching
There are five specific reasons why mental health literacy directly improves coaching outcomes.
It builds the coach's confidence. A coach who understands the basics of mental health — the continuum, the warning signs, the difference between distress and clinical disorder — approaches emotionally complex sessions with more composure and clarity rather than anxiety or avoidance.
It improves the quality of the conversation. When a coach can name what they are noticing — gently and without clinical presumption — clients feel seen in a way that accelerates trust and deepens the work.
It helps coaches recognise when referral is appropriate. Over the past 12 months, 44% of coach practitioners stated that they had referred one or more of their clients to a medical professional or therapist. Globally, there is an upward shift in these referrals. International Coaching Federation This is a sign of a maturing profession, not a failure of coaching.
It reduces stigma. When mental health is normalised within the coaching conversation — treated as part of human experience rather than as a separate clinical concern — clients are more likely to disclose what is actually happening for them.
It strengthens psychological safety. Psychological safety — the ability to speak up about ideas and concerns free from interpersonal risk — is foundational to the kind of environment where difficult things can be explored honestly. International Journal of Mental Health Systems Coaches who understand this and create it deliberately produce better outcomes.
Recognising Early Warning Signs
One of the most valuable skills a coach can develop is the ability to notice early signs that a client may be struggling — before those signs become a crisis, and before the client is ready to name them directly.
These signs tend to cluster into three categories.
Verbal cues include statements of being stuck or unable to keep up, negative or hopeless framing of situations that would previously have been approached with optimism, difficulty articulating goals clearly, and expressions of feeling overwhelmed without being able to identify why.
Behavioural cues include withdrawal from sessions, cancellations without clear reason, reduced engagement or follow-through that is out of character, and noticeable irritability or changes in energy during sessions.
Emotional cues include tearfulness, flat affect, heightened emotional sensitivity, and emotional swings that seem disproportionate to the content being discussed.
None of these signals, taken in isolation, constitutes a clinical concern. But a pattern of them — particularly one that represents a change from the client's usual presentation — warrants gentle acknowledgement, direct but compassionate attention, and potentially a conversation about whether additional support would be helpful.
The key principle is that noticing is not diagnosing. A coach who says "I've noticed you seem to be carrying something heavier than usual this week — would it help to explore that?" is practising good coaching. A coach who says "I think you may be depressed" is working outside their scope.
Opening Space Safely for Mental Health Topics
How a coach opens space for emotional and psychological content is as important as whether they open it. The approach must be non-judgmental, non-presumptuous, and centred entirely on the client's own experience.
Some language approaches that work well in practice:
Invite reflection rather than assume: "How have you been feeling lately — not just about the goals, but generally?" creates an opening without presumption.
Name what you are noticing gently: "I'm sensing there might be something weighing on you beyond what we've been working on. Is that something you'd like to bring in?" signals attentiveness without overstepping.
Allow the client to set the pace. Not every client who is struggling will want to explore it in a coaching conversation, and that is their right. Creating the opening is the coach's responsibility. Whether to step through it belongs entirely to the client.
Reinforce confidentiality and psychological safety explicitly, particularly when the conversation moves into more sensitive territory. Clients need to know not just intellectually but experientially that what they share will be held with care.
Language That Builds Trust and Reduces Stigma
The specific language a coach uses when mental health enters the conversation has a significant effect on whether the client feels safe to continue or closes down.
Person-first language — speaking of someone as "a person experiencing anxiety" rather than "an anxious person" — separates the human being from the experience and signals that the coach sees them as more than their current struggle.
Validating language normalises the experience without minimising it. "It makes complete sense that you're feeling this way" communicates understanding without judgment. "Many people feel overwhelmed during periods like this" reduces the isolation that often accompanies distress without invalidating the client's specific experience.
Avoiding diagnostic terms and clinical labels is not about being evasive — it is about staying within the coaching role. A coach is not qualified to diagnose. Using diagnostic language suggests a clinical assessment has been made when it has not, and can either alarm the client or, conversely, give unwarranted reassurance about the nature of what they are experiencing.
Open, compassionate questions — "What is this feeling showing up as for you?" — keep the exploration in the client's frame of reference rather than the coach's interpretation of it.
Practical Tools for Mental Health-Aware Coaching
Coaches do not need therapeutic qualifications to support client wellbeing effectively within their scope. There are several evidence-informed approaches that sit squarely within the coaching role.
Strength-spotlighting involves deliberately identifying and naming a client's existing capabilities, particularly when they are struggling to see them. Exploring past instances where the client navigated difficulty successfully builds the evidence base for resilience in the present.
Values alignment is particularly powerful during periods of stress or overwhelm. Clarifying what matters most to the client, and using those values as anchors for decision-making and priority-setting, provides both clarity and a sense of grounding when external circumstances feel chaotic.
Wellbeing scaling — using a simple 1-10 scale to assess current emotional state at the start of a session — serves multiple purposes. It creates a shared language for emotional experience. It allows the coach to track changes over time. And it gives the client a moment of structured self-reflection that can surface awareness they may not have had before the session began.
These tools are not therapeutic interventions. They are coaching-appropriate strategies that support mental wellbeing, build resilience, and contribute to a coaching relationship that the client experiences as genuinely supportive rather than purely task-focused.
When to Refer
Knowing when to refer a client to a mental health professional is one of the most important competencies a coach can develop. Both new and experienced coaches can find themselves willing to work beyond their capabilities. Working with people who experience mental health difficulties may be appropriate for coaches who have a background in counselling, but coaches without such training may find it difficult to identify the limits of their abilities. Brookes University
Clear indicators that referral should be considered include persistent and intense negative emotions that do not shift over multiple sessions, significant impairment in the client's ability to function in daily life or work, expressions of hopelessness that go beyond normal frustration, any indication of risk to the client themselves or others, and situations where the client's distress is clearly rooted in clinical-level trauma, disorder, or crisis.
Referral is not a failure of the coaching relationship. It is an act of professional responsibility and genuine care. A coach who refers a client at the right moment — warmly, clearly, and with a follow-up conversation to ensure continuity — demonstrates exactly the kind of professional maturity that strengthens rather than undermines trust.
Professional coaching bodies' guidelines have evolved to address increasing mental health challenges, with recent updates specifically calling out the rise of coaching being used for mental health support. Most critically, risk-based red flags requiring immediate attention include potential self-harm, significant distress, disconnection from reality, and inability to maintain coherent conversations. The presence of multiple indicators, particularly when considering their duration, frequency, and intensity, should prompt coaches to initiate referral. Philosophyofcoaching
The Ethical Foundation
Everything discussed in this blog rests on an ethical foundation. Mental health literacy in coaching is not simply about competence — it is about responsibility.
Coaches who engage with the psychological dimension of their clients' lives carry a duty of care that extends beyond the achievement of stated goals. Maintaining clear professional boundaries, operating within scope, knowing when to refer, holding confidentiality rigorously, and continuing to develop their own self-awareness and supervision practice are not optional extras. They are the ethical bedrock of high-quality coaching work.
At Summers Performance Management, this dimension of coaching is treated with the seriousness it deserves. Performance and mental health are not separate conversations. They are deeply interconnected — and supporting a client's mental wellbeing, within appropriate professional boundaries, is inseparable from supporting their performance.
