Hi there

Clinical psychology provides ideas and approaches to therapy that assist practitioners in addressing the psychological behaviours of clients or patients that they don't want to see and in fostering feelings of wellbeing, self-discovery, and personal growth. Clinical psychologists can conduct psychological examinations, identify mental, emotional, and behavioural abnormalities, and suggest appropriate treatments.

There are several short-term courses and certifications, including CBT, REBT, NLP, and others. All of these courses are about treatment.

Numerous online sites, such udemy and others, will give you short-term courses as well.
