What is an Assistant Psychologist?
An Assistant Psychologist (AP) is an employee who holds at least a bachelor’s degree in psychology and assists higher-ranking psychologists, typically in clinical environments. APs cannot work on their own and are under supervision. They help with the biopsychosocial assessments that guide the formulation of treatment plans, which often involve data collection, preliminary interviews, and administrative tasks.
What is a Clinical Psychologist?
A Clinical Psychologist is an autonomous mental health practitioner who specialises in the assessment, diagnosis, and treatment of individuals with emotional and behavioural concerns. They have completed a Doctorate in Clinical Psychology (DClinPsy) and are registered with the Health and Care Professions Council (HCPC) in the UK. Using evidence-based practices, clinical psychologists provide therapies like CBT, various forms of psychodynamic therapy, and many others.
