Firstly, what is Cognitive Behavioural Therapy, or CBT? Imagine it as a set of mental "tools" to help people understand and alter their thought processes, thereby affecting their behaviours and emotions. Now, this therapy can happen in two main ways: as an individual session (just you and the therapist) or as a group session (you, some other people, and the therapist).

• It's cheaper: More people attending means the cost is divided, so everyone pays less. Think of it like going to a concert – a ticket for a group is often cheaper per person than a single ticket.

• The therapist gets more info: Observing clients interact within a group can provide the therapist with more insight. It's like a teacher observing a group project; they get a broader understanding of each student's behaviour and interaction style.

• Seeing others improve can motivate: Just like how seeing a friend ace a test may push you to study harder, observing others improve in group therapy can encourage individuals to work on their issues.

• Opportunity to test new behaviours: With a group, one can test-drive new behaviours and get immediate feedback, much like trying out a new dance move at a party and seeing people's reactions.

• Some people may not feel comfortable in a group: Just as some of us freeze up when asked to speak in public, some people might find it hard to express themselves openly in a group therapy setting.
• Possible negative group dynamics: If the group isn't well managed, it can potentially be harmful, similar to how a poorly led group project can become chaotic or counterproductive.
