What Is a Psychologist – and How Can They Help?

If you have ever been told “it might be helpful to speak to a psychologist”, you may have wondered what that actually means.

What does a psychologist do?

Is seeing a psychologist only for mental health difficulties?

Do I need a diagnosis?

And how is a psychologist different from a psychiatrist, therapist or counsellor?

These are very reasonable questions. Psychology covers a much wider range of areas than many people realise.

What is a psychologist?

A psychologist is a professional who has undertaken extensive training in understanding how people think, feel, behave, learn, communicate and relate to the world around them.

Psychologists are interested not simply in what someone is finding difficult, but in understanding why those difficulties might be happening.

This can involve considering many different aspects of a person's life, including their development, relationships, experiences, environment, learning, emotional wellbeing, sensory needs, physical health and neurodevelopment.

For children and young people, psychologists may also consider what is happening at home, at school and in other environments.

The aim is to build a fuller picture of the person rather than focusing on a single behaviour, symptom or diagnosis.

You don't have to be in crisis to see a psychologist

One common misconception is that you only see a psychologist when something is seriously wrong.

That isn't the case.

People speak to psychologists for many different reasons.

“I don't really understand why I find certain things so difficult.”

“My child is struggling, but we don't know why.”

“Something doesn't quite fit and I'd like to understand it better.”

“I wonder whether I might be autistic or have ADHD.”

“I already have a diagnosis, but I don't know what it actually means for me.”

Sometimes there is a clear difficulty. At other times, someone may simply want a better understanding of themselves, their child or their experiences.

What does a psychologist actually do?

There isn't one single type of psychology appointment.

Depending on the reason someone has come, a psychologist might spend time talking with the person, gathering their developmental history, exploring their experiences, completing psychological or cognitive assessments, using specialist assessment tools, speaking with family members or schools, or reviewing information from other professionals.

An important part of psychological work is formulation.

Formulation means bringing different pieces of information together to develop an understanding of what may be happening and why.

Rather than simply asking:

“How do we stop this behaviour?”

A psychologist might explore:

• What might this behaviour be communicating?
• When does this difficulty happen – and when doesn't it?
• What demands are being placed on this person?
• What experiences might have shaped the way they respond?
• What are their strengths?
• What could make things easier?

That understanding can then help guide practical recommendations and support.

Do psychologists diagnose?

Some psychologists are trained and experienced in undertaking diagnostic assessments, including assessments relating to neurodevelopmental differences such as autism and ADHD.

However, diagnosis is only one part of psychology.

Sometimes an assessment results in a diagnosis. Sometimes it doesn't.

Either way, psychological assessment can still provide valuable information about a person's strengths, needs and experiences.

A good assessment should therefore be about more than asking “Do I have this diagnosis?”

It can also help answer:

“Why might life feel harder for me in certain situations, and what might help?”

Psychologists, psychiatrists, counsellors and therapists – what's the difference?

There can be overlap between these professions, which understandably makes things confusing.

A psychiatrist is a medically qualified doctor who specialises in mental health and can prescribe medication.

A psychologist is trained in psychological assessment, formulation and psychological intervention. Depending on their professional training and area of practice, psychologists may work with mental health, neurodevelopment, trauma, learning, relationships, behaviour and many other aspects of human experience.

Counsellors and therapists provide different forms of therapeutic support and may have training in particular approaches or areas of difficulty.

The right professional depends on what you would like help understanding or changing.

Psychology isn't just about difficulties

Psychologists are interested in difficulties, but we are equally interested in strengths.

Understanding someone psychologically shouldn't mean producing a list of everything they struggle with.

It should also recognise what they are good at, what matters to them, how they have adapted, the strategies they have developed and the environments in which they thrive.

This is particularly important when working with neurodivergent people.

Being autistic or having ADHD, for example, should not automatically be viewed as something that needs to be fixed. A neuroaffirming psychological approach considers how an individual's way of thinking, processing and experiencing the world interacts with the environments around them.

Sometimes the most helpful change isn't changing the person.

It's changing what is happening around them.

What might seeing a psychologist help with?

People may seek psychological input for many reasons, including difficulties with emotions, behaviour, relationships, education, work, attention, organisation, sensory experiences, anxiety, trauma or significant life experiences.

Others may want to explore autism, ADHD, learning or cognitive differences, or simply understand patterns that have been present throughout their lives.

Parents may seek support because they can see that their child is struggling but aren't sure what sits underneath that struggle.

Adults may reach a point where they begin looking back across their lives and wondering:

“Why have I always found this harder than other people seem to?”

There doesn't always need to be a clear starting point.

Sometimes wanting to understand is enough.

Looking at the whole person

Perhaps one of the most important things psychology can offer is the opportunity to bring different pieces of someone's story together.

A person is more than a diagnosis.

A child is more than their behaviour at school.

And difficulties rarely exist completely independently of someone's experiences, relationships and environment.

Psychology gives us a framework for becoming curious about those different pieces and considering how they might fit together.

Ultimately, the goal isn't simply to give something a name.

It's to develop a better understanding of the person – and use that understanding to help identify what might make life easier, healthier and more manageable.
