An experiment was done in which patients suffering from the same disease were divided into two groups, one treated by a young doctor, taking ordinary packaged drugs, and the other treated by a famous expert, taking “special drugs” – in fact, the same drug in a different package. As a result, the patients in the expert treatment group worked quickly and the treatment effect was significantly better than that of the non-expert group. This is often referred to as the “suggestion effect” in psychology. In the experiment, what really worked was not the “experts”, “special drugs”, luxury packaging and a series of gimmicks, but the trust in the doctor and the drug that the patients built up in the process. It is this trust that gives the patient confidence in the treatment, thus stimulating a good neurophysiological response and a benign development of the disease. This experiment not only demonstrates the tremendous energy induced by positive suggestion, but also vividly illustrates what it means to be a “believer in medicine”. As doctors, we are inevitably questioned. In our daily communication, we often hear our colleagues lament that the most difficult part of being a doctor is not to treat, but to make patients believe in the treatment. I feel the same way, as a psychologist, it is even more difficult to win the trust of patients. In the past eight years of practice, I have encountered many challenges in my clinical work. From the initial embarrassment to the current comfortable response, it has been a long process, from which I deeply appreciate that, in the face of patients’ questions, self-confidence is the most powerful weapon for doctors. Not long ago, I received a male patient in his fifties, he was well-dressed and dignified, once he entered, he looked at me with distrustful eyes, and then slowly spoke: “Originally I wanted to go to a hospital psychology department, I heard that there is a male doctor there, his age is about the same as mine, and it is more appropriate to communicate. But he’s not here today, and I’m in a hurry, so I’ll go here first.” The implication is that I don’t like to be seen by a young female doctor like you, and that I will change doctors at any time. Experience told me that this was a difficult patient to deal with, who held a strong suspicion of doctors and needed double the enthusiasm to dispel that wariness. I first affirmed the planned nature of his work and implied that changing plans was not always a bad thing, and then asked him to talk about the situation. He spared no words about his problems and reluctantly underwent a psychological examination. When I told him he needed anti-anxiety medication and psychotherapy, he looked at me skeptically and was noncommittal. I explained the condition, explained the advantages and disadvantages, and emphasized, “You can go to another doctor without seeing me, but you must receive treatment.” Perhaps my sincerity impressed him, and he came the next day as promised. But just before he took his seat, he threw out these words: “I hesitated for a long time before coming here today, and I hesitated for three reasons: first, our age difference is more than 20 years, and my experience is richer than yours, which you cannot experience; second, I have a successful career and strong assets, and I hope I won’t hurt you by saying this – -the content of my life is unimaginable and incomprehensible to your class; third, I have no good feeling for women, and it is difficult to push the conversation.” I must admit that despite being able to respond with confidence, I still felt uncomfortable with such a challenge. Doctors are human beings with a need to be respected and a sensitive sense of self-esteem, and in the face of questioning, they can feel more or less frustrated, frustrated, embarrassed and angry. However, doctors are not ordinary people, we are responsible for treating patients and saving lives, so we cannot gamble, we cannot be capricious, and we cannot indulge in our emotions and inaction. I replied calmly, “The fact that you came despite all your worries shows that you trust me, and I want to thank you. As for life experience and assets, you do outshine me, but these two things don’t seem to solve your problems, do they? I have psychological expertise and therapeutic techniques, which you don’t have and which you need most right now.” He nodded slightly. Next, I turned the tables and enlightened him, “You say you don’t have a good feeling about women, and I’m curious to know how you got that impression? Do you think your way of thinking is a bit extreme if you generalize the whole with individual phenomena?” He gazed at me, seemed to be deep in thought, and then, gradually, opened up to me. The rest of the consultation went very well, and he nodded understandingly at times and smiled happily at others, the real pleasure of being accepted and understood. At the end of the counseling session, he was so happy that he decided to persuade his lover to come to marriage counseling with him. I knew that I had diffused his doubts with my confidence. Age, gender, education, experience …… patients can question us for all kinds of reasons, but we must keep in mind that we have what they do not have, and that is the professional knowledge and therapeutic skills, which is the fundamental condition for them to seek help from us, and the advantage we should try our best to show. In the face of doubt, we must put aside negative emotions such as frustration and irritation and let the patient see our ability and feel our calmness, so that they can devote themselves to treatment. When trust is established, the experimental effect mentioned at the beginning of this article will be presented. As a result, the patient gains the most from the treatment, and the doctor gains a mature mind and a charismatic personality – assets that will benefit us for the rest of our lives.
