Not everyone wants to, or can, commit to long-term or on-going therapy. But that doesn't mean it isn't possible to have a good experience of therapy, where you can really think in detail about a specific issue that might be affecting you.
So what kind of things can be effectively worked on in short-term therapy? Here is a list of some of them:
Relationship difficulties or breakdown
Important life decisions, such as choices around work or a relationship
Response to life events - such as Brexit (and no, I am not joking here!)
How many sessions would be useful?
I would say that the minimum length would be 6 sessions, whereas the optimum length would be 12-16 sessions. With that length of time, we can really get to know a difficulty much better, make important changes and focus on attachment in greater depth.
What is involved in short-term therapy?
Essentially, short-term therapy is no different to long-term work, but tends to be more focused a specific area or difficulty, rather than developing organically. It might involve 'homework' between sessions. That might or might not involve tasks (like in CBT), but might include my asking you to become more aware of your thinking and responses to specific events or thoughts you have. Homework isn't a definite though - I would think about it with a client individually, and if it feels wrong for you, then I don't push it.
