From the author: Clients often ask questions about the sustainability of changes as a result of therapy that have already occurred. What does this stability depend on and what guarantees can therapy provide? This is discussed in this article. If there is no further growth, then decline is near. Seneca The moment when a problem ceases to be such for a person is surprising. Everyone reacts to such a moment completely differently. Someone happily fills their chest with the aroma of freedom, while others feel a strange emptiness - “how, is that all?” There are also those who doubt that the problem has really gone away. Their beliefs call into question the disappearance of a personality problem that has not gone away for many previous years. It is they who ask the question from the title of the article after the end of therapy: “Won’t my anxiety come back?” The question is actually somewhat provocative. I don’t want to use the word “manipulative,” although there are echoes of this. Because a manipulation question usually contains a presupposition, and if you start answering it, you automatically agree with this presupposition. This type of question is well known: “Have you finished drinking cognac in the morning?” Here the presupposition is that you drink cognac in the morning. In the question about anxiety, there is a presupposition of doubt that the problem will go away completely. The client still has doubts and fears that the symptoms of the problem will return even after it has gone away. It makes no sense to answer this question either “yes” or “no”. It is better now to continue working with the client’s remaining doubts than to let him go. A small doubt may only seem so, but is actually the tip of the iceberg of serious internal resistance to change. In my opinion, such questions are an indicator of the sustainability of therapy changes. More precisely, the absence of such questions is a guarantee of sustainability of changes. Changes as a result of therapy will be sustainable if they take into account the highest levels of change. We are talking about levels of beliefs, values, personal identity. For example, the client feels significant relief, but cannot believe that this has happened and the result will last. For me, this is a signal that not everything has been worked out at the level of beliefs. It may well turn out that there is hidden the belief “Changing yourself can only be achieved through hard work,” while positive changes as a result of therapy occurred quite quickly. Remnants of doubts may disappear on their own. To do this, the client needs a kind of “trial period”, during which he will make sure that everything is still good. This is an ideal option. In general, it is difficult to talk about guarantees in therapy. Rather, they are determined by how the client formulated his request. The movement towards the implementation of this request is a process associated with constant changes. They occur at every stage of therapy. It is not always possible to predict the scale of these changes: they can be barely noticeable, or they can be realized in the form of a sharp jump. The client develops and grows during therapy, learns new ways of responding to the world, changes his attitude towards himself, and masters effective methods of social adaptation. Moreover, this growth continues after the completion of all procedures and sessions. If the client expresses doubts about the sustainability of changes, this also indicates his low involvement in the therapy process. He formally went through all the stages, but was not imbued with the process of change, teaching himself new important life skills. In this case, there will be no growth as such, since the client was not initially aimed at it. To summarize what has been said, I would like to express my thought this way: changes as a result of therapy will be sustainable if a person is interested not only in solving the problem, but also in his future growth and development. If this growth ends when you leave the office from the last session, then there is a possibility that the changes will reverse later. The Roman Stoic expressed himself very clearly on this topic.
