 Now, I am going to shed some light on research and multiple role relationships. Dependent relationships are characterized by a disparity in power and status between the researcher and research participants that compromises the ability of participant to provide free consent to participate or withdraw from a project they are already participating in. At times, our research participants are in such a situation that they cannot choose from their own free will whether they want to be a part of some research or not. For example, if a professor of psychology is going to conduct a research on students' classroom behavior and he tells his own classroom students that this is your assignment, that you have to be the part of this research for a three-month time period, they have to be the part of that research because their professor has given them this assignment and he is studying their behavior. So, the situation there is that they cannot withdraw from it. Multiple ethical obligations arise when the research participants are also current and previous clients of the researcher. Now, a mental health professional is doing his research and at the same time he is using his clients as participants in the research. So, for the previous or current clients, it is very difficult or challenging to withdraw yourself from that mental health professional. We have seen a lot of new herbal medicines in the research of neuropsychology. So, the practitioners of neurology or neuropsychology try different elements like Parkinson's or dementia. They also test the herbal medicines in different experiments to see if they are getting good results or not. And the participants, because they are being the clients, they cannot say yes or no. They have to take them. However, their participation could jeopardize the therapeutic services being rendered. But in this way, if a client is asked to withdraw from their research, when you take it as an experiment, then your therapeutic practice can basically disturb it because it is not considered a good thing. Problems typically arise when participants at the student or client feel obliged to participate or not to withdraw or are likely to have a reasonable belief that might experience this benefit even if the relatively minor by declining to participate or by withdraw. This situation becomes very intense when a student or a client feels that he is not getting any benefit from this research. However, if he refuses to participate in this, then he will be very upset because his teacher or therapist will be upset. So, this situation becomes very critical. Dependent relationship can be particularly impactful when working with vulnerable populations. Now, as we talked about the teacher-student relationship, we talked about the different role of the teacher-student relationship. We also talked about the therapist or client. There are different roles and relationships. So, dependent relationships become more impactful when we talk about vulnerable groups. Researchers should ensure that appropriate consents are obtained from any gatekeepers to participants. For example, school principal, parents, or legal guardians. That means that we should take every individual who is from a small to a large level in some research and that is a part of this research. We should take their informed consent, their permission, without thinking that their position is very small in our research. Then, dependent relationship should be definitely very impactful when working with vulnerable groups. Now, to avoid further unethical problems and current and previous clients should not be included into research unless needed benefits are likely or not otherwise available. We can only make our clients part of our research at that time when we are sure that we do not have any other population and this research will create a very high benefit and we should not stop it in any way and the unavailability of any other potential participants are to be seen for this research. So, some research on clients can be done by keeping ethical guidelines in front of them. Even here, care should be taken to present a sincere opportunity to decline the participation in research. If even your client is participating in your research, still he should have this privilege that he can say to withdraw from that research. Special safeguards such as participant advocate should be introduced when the power differential between the researcher and the potential participants is especially large. A situation where a relationship is developing that a therapist or a client is a research participant, an advocate should be there who supports the rights of the participant that if he wants to withdraw in a situation, he can get proper legal support and his mental health professional or therapist can never be disturbed by any position or can't stop his treatment or can't harm him in any other psychological way. So, when we talk about multiple roles in research, it is very important to see that if these roles are overlapped, then because of them, no potential dignity should be harmed and these roles should be proceed in very ethical manner.
