Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Assessment of motives of enrollment in a trial and patient's attitude to RCT based on elaborated questionnaires for both groups
Time Frame: on enrollment

The specially designed questionnaire for the study group includes 9 questions. Based on the data obtained, we will be able to draw conclusions about the motives for participating in RCTs, the level of trust towards a doctor, and adherence to treatment after the end of the RCT.

The questionnaire for the control group includes 8 questions with 3 possible answers as well. Based on the data obtained, we will determine the level of patient awareness of RCTs and the willingness to participate in the trial in the future. This questionnaire is exploratory, each question is considered individually, which allows us to make a more detailed analysis of various aspects of our study.
