Diagnostic Process Therapists may ask clients questions about their daily lives, ask clients to fill out surveys, or talk with third parties such as parents and spouses to formulate an accurate diagnostic picture of the person. Diagnosis of mental illness is at least partially subjective.

Examples of different types of therapies used in counselling are acceptance and commitment therapy (ACT), cognitive behavioural therapy (CBT), mindfulness, couples counselling, and group therapies for grief, substance abuse or other issues.

Counselling is a form of 'talk therapy'. It is a process where an individual, couple or family meet with a trained professional counsellor to talk about issues and problems that they are facing in their lives. Professional counselling is confidential and non-judgmental.

Directive and non-directive counselling are the major types in counselling, with eclectic counselling being the third type.
