There is considerable interest in the various ethical problems associated with undertaking health and social science research. Participants in such research are often considered vulnerable because of their health status, social position, or dependence on others for health and welfare services. Researchers and ethics committees pay scrupulous attention to the identification and amelioration of risks to participants. Rarely are the benefits to participants of engaging in research highlighted or drawn to the attention of potential participants. Such potential benefits need to be considered by researchers and reviewers when considering the balance of benefits and harms associated with research projects. In this paper, we particularly consider the psychotherapeutic benefits of participation in research. © 2012 The Authors International Journal of Mental Health Nursing © 2012 Australian College of Mental Health Nurses Inc.
