Online counseling, an intervention that has evolved alongside technological advancements and become integrated into individuals' lives, has gained even more popularity. At this point, it is essential to investigate the acceptance and usage of online counseling by mental health professionals. This research was conducted with 35 mental health professionals (psychologists and counsellors) who provide both online and face-to-face counseling. In the study, Q methodology was used to better understand the subjective thoughts, attitudes, and beliefs of participants to understand their behaviors regarding the acceptance and use of online counseling according to the UTAUT model. As a result of the research, it was found that factors related to the acceptance and usage of online counseling were grouped into two factors for mental health professionals. The research findings indicate that mental health professionals are grouped into two factors regarding factors related to the acceptance and utilization of online counseling. It has been observed that performance expectations and facilitating conditions influence the acceptance and utilization of online counseling for participants in Factor 1, while effort expectations and facilitating conditions influence the behavior of acceptance and utilization for participants in Factor 2. Additionally, it was found that mental health professionals in Factor 1 have a more positive attitude towards online counseling, whereas those in the second group prefer face-to-face counseling over online counseling.
