This study explored counsellors' experiences with online therapy during the COVID-19 crisis, which presented an opportunity to examine how counsellors evaluated the drawbacks, benefits, and appropriateness of online therapy. Data collected through surveys from 114 professional counsellors, school counsellors, addiction counsellors, clinical social workers, and marriage and family therapists in the United States were analysed. Results indicated the level of preparation for online therapy varied. The process was heavily impacted by technical functionality and perceived as more effective face-to-face. Counsellors found clients disengaged and distracted rather than comfortable and open. The effectiveness of online therapy was more strongly associated with client characteristics and treatment approaches than with diagnoses and treatment goals. Interpretations, clinical implications, and further research recommendations are provided.
