For this purpose, before starting the study, a sequence of letters a and b (so that both are equal) is created through randomization.com, according to the sample size. After the start of the study, each participant who met the entry requirements will receive a number based on the time of entry into the study and will receive intervention a or b from a pre-prepared sequence list, Blinding description: The people in charge of the initial and final evaluations as well as the people in charge of data analysis are not aware of the category of participants. Depending on the nature of the study, researchers and participants will be aware of the type of categorization. N/A Multiple Sclerosis.

The therapist then teaches the general problem-solving strategies (goal, plan, execution, check) and how to use field-specific strategies to design and execute the plan and achieve the intended goal. Then, for example, an experimental goal is selected and the general and specific strategies of the field for that goal are practiced with the authorities. From the third session onwards, work on the selected goals of the clients begins. The client plans for its own purposes. The therapist, as an active observer, guides the client through guided discovery, if, given his or her expertise, the program is likely to pose a risk to the client or contain items that make it impossible to reach the target. Guides.
