At present, different services of psychological therapy courses online are being opened in profusion. Recently such ways of therapy have been only experiments of using new technologies in medical practice. But soon these experiments demonstrated great advantages and pretty high effectiveness of such methods of therapy in cases of different mental health disorders and also as a simple psychology therapy assistant online. In all cases the effectiveness of a new method was shown clearly. As a medical method in general psychological therapy online courses are still being examined. Usually such a psychological therapy online course is a sort of counseling through the internet. And although such a technique was developed not so long ago, there are already different misconceptions connected with a therapy online course. The question about whether they work or not and how effective they are is going to be answered further. The main misconception about the method is the overall efficiency of such methods. Many medical professionals still think that a therapy online course can not be really helpful and such a thing as online therapy is just impossible. But there are many different examples when patients benefit from therapy online courses. For some groups of people it is much easier to have a mental health medical help through the internet. Shy and introverted people prefer to keep such help private and the internet is probably the best instrument to achieve this goal. All these numerous examples prove the possibility of therapy online courses. And they are not only possible but also the internet gives several advantages that cannot be achieved in a real world. The internet communications are very flexible, so the patient can ask for a therapy online course anytime and from any part of the world. Another misconception about therapy online courses is caused by the limited knowledge of modern technologies. Many people and even doctors still believe that therapy online courses are only performed by e-mail. But, in fact, it is not true. There are many different opportunities to communicate that the internet provides with these days. In many cases a patient can be observed through electronic letters and this technique will still be effective. But there are also possibilities to have a therapy online course in the interactive way. Different sorts of audio and video conferences are widely spread. Web forums or message boards are also workable. A patient can look through all the available messages on forum to find similar questions and in many cases simple questions can be answered even without contacting the medical professional. By the way, chat is another method of therapy online course. If the number of participants in the chat room is limited, such a method works well as a therapeutic technique (of course, a medical professional is needed here with administrator rights for the chat room). Different experiments in this field revealed high effectiveness of chat rooms in treatment of different psychological conditions. All of the above-said explains the growing popularity of online therapy.
