Technology is rapidly evolving, and mental health professionals are increasingly using technology in their clinical work. In reaction to this shift, it is important that research examines the ethical implications of online behaviors. The current study examined the online practices of graduate students in the mental health field and generated prediction models for online client searches and best practices in informed consent and online disclosure. The sample consisted of 316 graduate students in counseling, clinical, and school programs. Of those with clinical experience, a third had utilized the Internet to find information about their client. Progress in the participants' program, as measured by credits completed or in progress, and years of social networking experience were positively related to online client searches. The vast majority (over 80%) of individuals who conducted an online search did not obtain informed consent prior to the search. Curiosity was the most frequent reason given for conducting a client search. Previous professional discussions and belief that information online is private were not significant predictors of obtaining informed consent. The final analysis examined disclosure of client information and found that lower scores on ethical decision-making and years of social networking experience predicted online disclosure. This study is an important step in understanding the implications of the intersection of technology use, ethics, and clinical practice of graduate mental health professionals.
