If you’ve ever looked up a mental health concern, you’ve probably seen the letters DSM. It stands for the Diagnostic and Statistical Manual of Mental Disorders, the reference book clinicians use to name and describe mental health conditions. The current edition is DSM-5. It gives us a common language so psychologists, GPs, psychiatrists and insurers understand what we’re talking about.
That’s the straightforward bit. The rest needs care and context.
Why a psychologist may use the DSM
In psychological practice, DSM terms help with three practical jobs.
First, they let us communicate clearly with your GP or psychiatrist. If a psychologist writes “major depressive disorder, moderate, with anxious distress,” other clinicians know the cluster of symptoms we’re dealing with and maybe how severe they are.
Second, the DSM can support access to care. Many systems (referrals, rebates, care plans) still expect a diagnostic label. Using DSM language can unlock Medicare items and coordinated treatment. It’s a key that opens a door; it’s not the whole house.
Third, it can guide treatment planning. Some psychologists may work on the basis of focusing on each diagnosis research about common patterns and what tends to help. That research is their starting map. Others may take a “transdiagnostic” and individual (“idiopathic”) approach These aspects of behaviour include frequency, rate, duration, latency, topography, locus, and intensity or force.
From there, we adapt to you—your history, culture, relationships, work, strengths, and goals.
Why I don’t treat the DSM like a rulebook
Diagnostic labels are imperfect. They compress a complex human story into a short phrase. That’s useful for paperwork and professional shorthand, but it can miss meaning and context. Psychiatrist Allen Frances, who led a previous DSM task force, famously cautioned clinicians to treat the DSM as “a guide, not a bible.” That line lands with me. It’s one of the reasons I combine DSM language with a collaborative formulation: a plain-English account of what’s happening, why it makes sense, and what we can do about it.
The DSM also reflects its time and place. It has grown and changed alongside the medical model, the influence of insurers, and the realities of health systems. Therapists have mixed feelings about that. In two studies by Jonathan Raskin, most clinicians said they used DSM-5 largely because they felt they had to, while many also supported developing alternatives. I get that tension. I work in it daily.
How we’ll talk about diagnosis in session
Here’s what you can expect with me:
- We decide together. If a diagnosis is useful—for care planning, rebates, or shared understanding—we’ll use it. If a description and formulation serve you better, we’ll foreground those. We can do both.
- Labels are tentative, not identity statements. Diagnoses change as life changes. If new information emerges, the label should shift to fit the story, not the other way around.
- Functioning matters. A label describes a pattern; it does not measure how you’re coping, your values, or your quality of life. We’ll examine the domains of your life: recreation/leisure; work/career; intimate relationships; parenting; education/learning
community life/environment/nature; friends/social life; spirituality; family of origin; and
health/physical self-care. We’ll also ask about sleep, energy, concentration, relationships, safety, and day-to-day functioning because those are the levers that we can move together.
Culture and power count. Symptoms happen in a context—workplace pressures, family roles, migration stress, discrimination, trauma, housing insecurity. We nameexamine those factors explicitly so treatment targets the drivers, not just the smoke from the fire.
- Clear benefits, clear risks. We’ll discuss how a label might help (shared language, access to care) and how it might hinder (stigma, over-identification). You get a say in that balance.
Where the DSM helps, and where it can mislead
The DSM helps when we need a consistent definition. For example, in adult ADHD assessment, where criteria sharpen the difference between a lifelong attention profile and a short-term stress response. It helps in anxiety disorders where structured exposure or skills training have strong evidence. It also helps us coordinate care across multiple clinicians.
It misleads when complexity is flattened. Two people may meet criteria for the same depression diagnosis for very different reasons: grief, chronic pain, isolation, perfectionism, burnout, or moral injury at work. The same label, different mechanisms. Treatment should follow the mechanism, not only the name.
What sits alongside the DSM in my toolkit
I draw on a few complementary perspectives.
- Formulation first. We’ll
writedevelop a simple, shared explanation: howproblemsyour individual experience developed, what keeps them going, and what will help. This blends biology, psychology, relationships, culture and environment. - Process-based thinking. Rather than chasing labels, we target processes like avoidance, unhelpful perfectionism, rumination (“stuck thinking”), unhelpful focus on the past or future, identifying yourself in unhelpful ways, frustrated or unclear values, ineffective action, or interpersonal patterns. This lines up with where research is heading and keeps therapy practical.
- Alternatives, not replacements.
I keep an eye on recent developments, engaging in ongoing professional development to keep on “the cutting edge”, then translate what’s useful into the best everyday care for you.
What this means for you
You won’t be reduced to a code. You’ll be treated as a person with a history, values and aims. We’ll use DSM language when it serves you, especially for coordinated care and rebates, and we’ll refuse it when it gets in the way. We’ll prefer plain speech, clear goals and measurable changes in your daily life. If a diagnosis feels heavy or doesn’t fit, say so. We can re-frame it together.
You may like or accept labels because they make your experience feel recognised. If you don’t, we can keep our focus on the work: sleeping better, worrying less, feeling steadier, repairing relationships, returning to study or work, or whatever “better” looks like for you.
I’m accountable to the science, to Australian standards of practice, and to you. The DSM is part of that picture. It doesn’t define it. Our job is to understand what’s happening, choose well-supported strategies, and keep adjusting based on your feedback and results. That’s how we make psychological language useful, by making sure it serves you – to become the person you want to be, live the life you want to live in accordance with what really matters to you.
