Psychologist vs Psychotherapist
Scope of Practice
Psychologists
Because psychologists are regulated professionals, they have a clearly defined scope of practice.
They can:
Diagnose and treat mental health disorders
Conduct psychological assessments and tests
Engage in research and teaching
Advise on mental health policy
In some areas, psychologists work closely with psychiatrists and other healthcare professionals to provide comprehensive care.
Psychotherapists
Psychotherapists’ scope of practice is generally focused on the provision of therapy. They may:
Offer individual, group, family, or couples therapy
Use a range of therapeutic techniques to help clients manage issues such as anxiety, depression, trauma, and relationship difficulties
Refer clients to other professionals for assessment, diagnosis, or medication when needed
However, unless they are also psychologists or psychiatrists, psychotherapists typically do not
conduct psychological testing or formal diagnostics.
Approaches to Treatment
Psychologists
Psychologists often use evidence-based approaches in their practice, drawing from a wide array of therapeutic models. Some common approaches include:
Cognitive-Behavioural Therapy (CBT)
Dialectical Behaviour Therapy (DBT)
Psychoanalytic and Psychodynamic Therapy
Humanistic Therapy
Family Systems Therapy
Acceptance and Commitment Therapy (ACT)
Additionally, psychologists are uniquely qualified to select and interpret psychological tests, giving them a deeper understanding of a client’s underlying cognitive or emotional patterns.
Psychotherapists
Psychotherapists are trained to use one or more forms of psychotherapy, often depending on their area of specialisation. Their main focus is the therapeutic relationship and the process of talk therapy, which may include:
Cognitive-Behavioural Therapy (CBT)
Humanistic Therapy
Gestalt Therapy
Solution-Focused Brief Therapy
Mindfulness-Based Therapies
Interpersonal Therapy
Motivational interviewing
While some psychotherapists use integrative approaches, they may not have the training needed to conduct complex psychological assessments.
Regulation and Professional Bodies
Psychologists
Psychologists are generally regulated by national or regional boards, such as the Psychology Board of Australia or the American Psychological Association. These bodies set standards for education, ethics, and professional conduct.
Psychotherapists
Regulation for psychotherapists is more variable in Australia, there are professional bodies such as the Psychotherapy and Counselling Federation of Australia (PACFA) set standards and offer accreditation.
Which Professional Should You See?
Choosing between a psychologist and a psychotherapist depends on your needs:
If you are seeking psychological assessment, diagnosis, or need a formal report, a
psychologist is usually the best choice.
If you want support for personal growth, managing life transitions, or working through
emotional issues, a psychotherapist is very helpful.
If you are unsure, it is perfectly acceptable to reach out to either professional for an initial
consultation—they may refer you to the most appropriate practitioner.
